Opening Skinner's Box: Great Psychological Experiments of the
Twentieth Century Lauren Slater
The Man Who Mistook His Wife for a Hat Oliver Sacks
Bad Science Ben Goldacre
Video and Podcast Recommendations
In Opening Skinner's Box, Lauren Slater sets out to
investigate the twentieth century through a series of ten
fascinating, witty and sometimes shocking accounts of its key
psychological experiments.
Dr. Oliver Sacks recounts the stories of patients struggling
to adapt to often bizarre worlds of neurological disorder.
Here are people who can no longer recognize everyday
objects or those they love; who are stricken with violent tics
or shout involuntary obscenities; who have been dismissed
as autistic, yet are gifted with uncanny artistic or
mathematical talents. If inconceivably strange, these brilliant
tales illuminate what it means to be human.
Here Ben Goldacre takes apart anyone who published bad /
misleading or dodgy science – this book will make you think
about everything the advertising industry tries to sell you by
making it sound ‘sciency’.

Activity 1: Is Psychology a Science?
1. Read this online article: https://www.simplypsychology.org/science-psychology.html
2. Read and annotate the following essay.
3. Define key-terms that you are unfamiliar with as you read through the essays.
4. Consider whether psychology should be classed as a science.
5. Write half an A4 page stating whether you consider psychology to be a
science. Make sure you justify your position.
Discuss arguments for psychology as a science
One argument for psychology being a science is that it uses deductive and
inductive methods. Philosophers would make observations and then produce
general statements about the world called ‘natural laws’. Popper (1959) suggested
that this form of gaining knowledge could never be used to demonstrate the truth
of knowledge. Knowledge could be verified, but never falsified. Popper’s principle
of falsification leads to the process of deductive science. The outcome of
experiments allows the research to accept or reject the null hypothesis and thus
accept or refine the theory that generated the hypothesis. This process of gaining
knowledge is called deduction, reasoning from the general to the particular.
One argument against Popper’s principle of falsification comes from Kuhn (1962)
who argued that the logical view of science (induction or deduction) did not
actually represent how science evolves. He claimed scientists generally collect
data that fits with the accepted assumptions of that science. Thus, scientists seek to
find confirming instances of their hypotheses rather than disconfirming them. This
supports the ‘publication bias’, where research supports a popular position is more
likely to be published (Dickersin, 1990).
A second argument to justify psychology as a science is that it uses scientific
methods. From this perspective, psychology can be considered a science, because
scientific methods are the preferred method of investigation. The laboratory
experiment has become the most dominant mode of investigation in psychology,
offering the psychologist the opportunities for control and prediction that are absent
in less ‘scientific’ methods. For example, Peterson and Peterson carried out a lab
based study where they had an IV and DV and were able to predict that the
duration of STM is less than 30 seconds. Plomin compared blood samples of super
bright pps with the blood of average pps. He found more of the super brights had
the gene IGF2R than the average pps (IV = IGF2R or not, DV = IQ). This work supports
the genetic argument and is scientific, tightly controlled, objective and reliable. This
again suggests that Psychology can be a science.
One weakness of using the scientific methods is that they lack validity. Psychologists
may use the scientific method but research has been criticised for lacking internal
and external validity. One major criticism of internal validity is because of demand
characteristics operating in the study. Demand characteristics create predictable
responses from the participants so that they don’t behave normally.
Asch’s study and Milgram’s study have been criticised for having low internal
validity. Asch’s participants must have been affected by the task and thus did not
believe it to be real. Also, Asch’s study involved conformity on a relative trivial topic
(length of lines) and this may not tell us much about conformity in other settings (low
ecological validity). Moreover, Orne and Holland criticised Milgram’s research and
said that his participants were responding to demand characteristics, as individuals
so not receive and electric shock for spelling a word incorrectly.
A second argument for psychology as a science is that Psychology embraces
explanations at different levels ranging from the physical to the sociological. One
could make a lesser claim that at least some levels of psychology are scientific, such
as research into the neurobiology of dreaming or the biochemical explanations of
schizophrenia.
A criticism of this approach is that Kuhn claimed that the paradigm was the key
feature of any science – what characterises any science is a shared set of
assumptions and a shared methodology. If psychology consists of different levels or
kinds of explanation, some of which are more scientific than others, then it cannot
claim to have a paradigm. Thus, while some levels of psychology are scientific,
psychology as a whole cannot claim to be a science. On the other hand, we might
equally point to Rose’s view that biology was a number of different paradigms.
In contrast, arguments against psychology as a science is that it is deterministic. The
basis of the scientific approach is that behaviour is predictable: there are cause and
effect relationships which can be discovered and these explain human behaviour.
However, the determinist view raises difficulties over freewill and moral responsibility,
which might lead us to reject the scientific approach as a way to investigate human
behaviour.
A counterargument to this is that science is not deterministic. There are methods to
incorporate free will into determinism. E.g., Heather (1976) came up with the idea
of liberal determinism, the view that behaviour is determined to the extent that
people act consistently with their character. It is easier to reconcile this view of
determinism with the idea of free will, because the liberal view allows for choice
(free will) within a range of options (determinism). OR Soft determinism by James,
which suggested mental activities are subject to freewill whereas physical states are
determined.
A second argument against psychology as a science is that it is reductionist. To
carry out a scientific test, we must be able to observe whatever it is we are
investigating. This may seem a straightforward requirement, but it is not always so.
E.g., there are many events such as fear and motivation that we cannot observe
directly. Instead, we observe something else that we feel represents the thing we
are really interested in. For example, we may choose to define or operationalise
fear in terms of some psychological change (e.g., pupil dilation), or motivation in
terms of questionnaire response.
A weakness of this argument is that there can sometimes be a problem with
operational definitions. The consequence of this is that psychologists often explore
the relationship between two things (e.g., fear and motivation) without ever being
able to measure either of these directly. Instead, our observations are always one
step removed from the phenomena (e.g., fear) that we are really interested in
studying. The result is that psychologists end up measuring something different from
their intended phenomena and reach false conclusions.
A final weakness is that psychology is not objective. Any subjective experiences
such as opinions or experimenter expectations are excluded from the investigation.
In this way, we can be sure that the results are not distorted because of the
subjectivity of the investigator. There are many difficulties with objectivity, e.g.,
observer bias – when the researcher observed behaviour, such observations are
affected by the observer’s expectations. Interviewer bias and experimenter bias
lead to changes in participant’s behaviour as a consequence of the researcher’s
expectations.
However, Heisenberg’s uncertainty principle is derived from the observation that the
simple act of measuring a sub-atomic particle changes the behaviour of that
particle. Thus, true objectivity can only be an ideal of scientific research. The
concept of science as being objective is also challenged by those who point out
that science is as much a social activity as a mechanical application of correct
procedures (Jones and Elcock, 2001). The work of scientists is affected by prevailing
social attitudes and the day-to-day activities of scientists are affected by everyday
concerns.
Activity 1 Student Work: Is Psychology a Science?

psychology to be a science. Remember to justify your
position.
Activity 2: Who was Wundt and how did he contribute to
Psychology?
Use the information below, and any independent research you wish to conduct, to
write half an A4 page explaining Wundt’s contributions to psychology.
Wilhelm Wundt opened the Institute for Experimental Psychology at the
University of Leipzig in Germany in 1879. This was the first laboratory
dedicated to psychology, and its opening is usually thought of as the
beginning of modern psychology. Indeed, Wundt is often regarded as
the father of psychology.
Wundt was important because he separated
psychology from philosophy by analysing the
workings of the mind in a more structured way, with
the emphasis being on objective measurement and
control.
This laboratory became a focus for those with a serious interest in
psychology, first for German philosophers and psychology students,
then for American and British students as well. All subsequent
psychological laboratories were closely modelled in their early years
on the Wundt model.
Wundt's background was in physiology, and this was reflected in the topics with which
the Institute was concerned, such as the study of reaction times and sensory processes
and attention. For example, participants would be exposed to a standard stimulus (e.g.
a light or the sound of a metronome) and asked to report their sensations.
Wundt's aim was to record thoughts and sensations, and to analyze them into
their constituent elements, in much the same way as chemist analyses
chemical compounds, in order to get at the underlying structure. The school
of psychology founded by Wundt is known as voluntarism, the processing
of organizing the mind.
During his academic career Wundt trained 186 graduate students (116
in psychology). This is significant as it helped disseminate his work.
Indeed, parts of Wundt's theory were developed and promoted by his
one-time student, Edward Titchener, who described his system as Structuralism,
or the analysis of the basic elements that constitute the mind.
Wundt wanted to study the structure of the human mind (using introspection).Wundt
believed in reductionism. That is he believed consciousness could be broken down (or
reduced) to its basic elements without sacrificing any of the properties of the whole.
Wundt argued that conscious mental states could be scientifically studied using
introspection. Wundt’s introspection was not a causal affair but a highly practiced form
of self-examination. He trained psychology students to make observations that were
biased by personal interpretation or previous experience, and used the results to
develop a theory of conscious thought.
Highly trained assistants would be given a stimulus such as a ticking metronome and
would reflect on the experience. They would report what the stimulus made them think
and feel. The same stimulus, physical surroundings and instructions were given to each
person.
Wundt's method of introspection did not
remain a fundamental tool of psychological
experimentation past the early 1920's. His
greatest contribution was to show that
psychology could be a valid experimental
science.
Therefore, one way Wundt contributed to the
development of psychology was to do his
research in carefully controlled conditions, i.e. experimental methods. This encouraged
other researchers such as the behaviourists to follow the same experimental approach
and be more scientific. However, today psychologists (e.g. Skinner) argue that
introspection was not really scientific even if the methods used to introspect
were. Skinner claims the results of introspection are subjective and cannot be verified
because only observable behaviour can be objectively measured.
Wundt concentrated on three areas of mental functioning; thoughts, images and
feelings. These are the basic areas studied today in cognitive psychology. This means
that the study of perceptual processes can be traced back to Wundt. Wundt’s work
stimulated interest in cognitive psychology.
On the basis of his work, and the influence it had on psychologists who were to follow
him, Wundt can be regarded as the founder of experimental psychology, so securing
his place in the history of psychology.

contribute to Psychology? Write half an A4 page.

Calculations example of Wilcoxon Signed Ranks Test
Psychologists were interested in knowing whether a group of students’ ability to
memorise words was because of the ear that they used to hear the words during
listening tasks. In order to investigate this, participants were individually presented
with an audio recording of a list of words. These were randomly presented to the left
or right ear. Participants gave two sets of scores – words remembered correctly from
the left ear and words remember correctly from the right ear. When the mean and
standard deviation were calculated, it was found that the data was positively
skewed which suggested that the data was not normally distributed. As a result, a
Wilcoxon’s was used to examine the difference between each ear and to see if the
difference did not occur by chance.
Based on the information from the scenario above. Give three reasons
why Wilcoxon’s test was used (contextualise your answer).

Activity 4: How can we influence behaviour?
1. Watch the following tutorial on behaviourism. https://www.youtube.com/watch?v=xz56R0tBAvI
2. Read the abstract from Epstein et al., 2016 below and explain how
behaviourism (and reinforcement in particular) could explain
these findings.
Epstein et al., 2016
Abstract: One way to increase choice of healthy over unhealthy behaviours is to
increase the cost of less healthy alternatives or reduce the cost of healthier
alternatives. The influence of price on purchases of healthy and unhealthy foods
was evaluated in two laboratory experiments. In Experiment 1, thirty-two 10- to 12-
year-old youth were given $5.00 and allowed to purchase multiple portions of a
healthy food (fruit or vegetable) and a less healthy food (higher-fat snack). The price
of one type of food varied from $0.50 to $2.50, while the price of the other type was
held at $1.00. Increasing the price of a type of food reduced purchases of that type
of food, but did not lead to substitution with the alternative type of food. In
Experiment 2, twenty 10- to 14-year-old youth were given $1.00, $3.00, and $5.00 to
purchase healthy and unhealthy foods. The price of each food was raised and
lowered by 25% and 50%. Raising the price of healthy or unhealthy foods resulted in
decreased purchases of those foods, and income available interacted with price
to predict the pattern of substitution of alternative foods. These results show the
potential for controlled laboratory studies of price and food purchases, and show
that the substitution of healthier for unhealthy food is related to available money.

Explain how behaviourism (and reinforcement in particular) could
explain these findings.
Activity 5: How can we explain depression?
1. Read the information below on schemas (part of the cognitive approach) and
depression.
2. Conduct independent research online.
3. Explain how negative self-schemas may account for how an individual
develops depression.
A schema is a cognitive framework or concept that helps organize and interpret
information. Schemas can be useful because they allow us to take shortcuts in
interpreting the vast amount of information that is available in our environment.
However, these mental frameworks also cause us to exclude pertinent information
to focus instead only on things that confirm our pre-existing beliefs and ideas.
Schemas can contribute to stereotypes and make it difficult to retain new
information that does not conform to our established ideas about the world.
Schemas: A Historical Background
The use of schemas as a basic concept was first used by a British psychologist named
Frederic Bartlett as part of his learning theory. Bartlett's theory suggested that our
understanding of the world is formed by a network of abstract mental structures.
Theorist Jean Piaget introduced the term schema, and its use was popularized
through his work. According to his theory of cognitive development, children go
through a series of stages of intellectual growth.
In Piaget's theory, a schema is both the category of knowledge as well as the
process of acquiring that knowledge. He believed that people are constantly
adapting to the environment as they take in new information and learn new things.
As experiences happen and new information is presented, new schemas are
developed and old schemas are changed or modified.
Schema Examples
For example, a young child may first develop a schema for a horse. She knows that
a horse is large, has hair, four legs, and a tail. When the little girl encounters a cow
for the first time, she might initially call it a horse.
After all, it fits in with her schema for the characteristics of a horse; it is a large animal
that has hair, four legs, and a tail. Once she is told that this is a different animal called
a cow, she will modify her existing schema for a horse and create a new schema
for a cow.
Now, let's imagine that this girl encounters a miniature horse for the first time and
mistakenly identifies it as a dog.
Her parents explain to her that the animal is actually a very small type of horse, so
the little girl must at this time modify her existing schema for horses. She now realizes
that while some horses are very large animals, others can be very small. Through her
new experiences, her existing schemas are modified and new information is learned.
While Piaget focused on childhood development, schemas are something that all
people possess and continue to form and change throughout life. Object schemas
are just one type of schema that focuses on what an inanimate object is and how
it works. For example, most people in industrialized nations have a schema for what
a car is. Your overall schema for a car might include subcategories for different types
of automobiles such as a compact car, sedan, or sports car.
Other types of schemas that people often possess include:
Person schemas are focused on specific individuals. For example, your schema
for your friend might include information about her appearance, her behaviours,
her personality, and her preferences.
Social schemas include general knowledge about how people behave in
certain social situations.
Self-schemas are focused on your knowledge about yourself. This can include
both what you know about your current self as well as ideas about your idealized
or future self.
Event schemas are focused on patterns of behaviour that should be followed for
certain events. This acts much like a script informing you of what you should do,
how you should act, and what you should say in a particular situation.
What Is Depression?
Depression is a common and serious medical illness that negatively affects how you
feel, the way you think and how you act. Fortunately, it is also treatable. Depression
causes feelings of sadness and/or a loss of interest in activities once enjoyed. It can
lead to a variety of emotional and physical problems and can decrease a person’s
ability to function at work and at home.
Depression symptoms can vary from mild to severe and can include:
o Feeling sad or having a depressed mood
o Loss of interest or pleasure in activities once enjoyed
o Changes in appetite — weight loss or gain unrelated to dieting
o Trouble sleeping or sleeping too much
o Loss of energy or increased fatigue
o Increase in purposeless physical activity (e.g., hand-wringing or pacing) or
slowed movements and speech (actions observable by others)
o Feeling worthless or guilty
o Difficulty thinking, concentrating or making decisions
o Thoughts of death or suicide
Activity 5 Student Work: Explain how negative self-
schemas may account for how an individual develops
depression. Include any independent research you
completed.
Answer the above question in the space below.
Activity 6: How does our brain and nervous system
influence behaviour?
1. Read the below information on the biological approach to psychology.
2. Read this outline and evaluation of Brain Plasticity and Functional Recovery (a
very current and interesting area of Biopsychology that you’ll learn about at
A level):
https://www.tutor2u.net/psychology/reference/biopsychology-plasticity-
and-functional-recovery
3. Conduct independent research into studies that use brain scanning
techniques (such as fMRI and EEGs) to observe brain activity and behaviour.
4. What are the strengths and weaknesses of explaining human behaviour from
a biological perspective? Outline and explain two advantages and two
disadvantages of using this approach to explain human behaviour.
What assumptions do biopsychologists make?
Psychologists from the biological approach assume that behaviour and experiences
are caused by activity in the nervous system of the body. The things that people
think and feel, say and do are caused, one way or another, by electrochemical
events occurring within and between the neurones that make up their nervous
system, particular those in the brain. Many biopsychologists also agree that
because the development of the brain is determined (at least partly) by the genes
a person inherits, that behaviour may be influenced by genetic factors.
Furthermore, because the genes we inherit are the result of evolution, many
biopsychologists think that behavioural and psychological characteristics may have
evolutionary explanations.
How do biopsychologists explain human behaviour?
Biological psychologists explain behaviour by trying to relate it to the
functioning of the brain and nervous system. The brain can be subdivided
into many different areas and structures and biopsychological explanations
often focus on which brain areas are responsible for which types of thinking
or behaviour and how they connect with other functions and brain areas. For
example, biopsychologists believe that language in humans is governed by
two areas of the cerebral cortex, Broca’s area, which controls the production
of speech and Wernicke’s area, which controls the comprehension of
speech. These ‘speech centres’ are connected to a variety of other brain
areas including those involved in thinking and in auditory working memory.
Other biopsychologists focus more on the role of genetic influences in
particular types of behaviour. For example, it is widely believed by
biopsychologists that schizophrenia, a psychological disorder involving a
range of symptoms including hallucinations, delusions and disorganized
thinking and speech, is at least partly the result of inheriting a faulty gene or
genes. These genes are thought to influence the development of the nervous
system, making it vulnerable to malfunctioning in certain ways that produce
the symptoms of the disorder.
Biopsychologists believe that chemical processes in the brain can be an
important influence on behaviour. The brain relies on a large number of
chemicals (called neurotransmitters and hormones) to send signals between
neurones. Too much or too little of any of these chemicals can result in over-
or under-activity in various parts of the brain, which results in changes to
thinking, feeling and behaviour. For example, some researchers have shown
how behaviour can be affected by altered levels of sex hormones. Increased
testosterone leads to increased risk-taking, whereas increased oxytocin leads
to increased nurturing and social responsiveness.
How to evaluate studies
Generalisabiliy - basically, can the findings of the study be generalised to the
general population? Here are some questions to consider when writing about this…
where was this study conducted and can it be generalised to other countries?
how large was the sample size?
how many males and females took part in the study?
were the participants of varied ages?
Reliability - if the study were to be repeated, how likely is it that you’d get the same
results?
how much control did the researcher have over the experiment?
was is it a lab, field or natural experiment?
were there any extraneous variables?
were these allowed to develop into confounding variables?
Applications - how can a study be used to support theories?
does it provide evidence for a specific theory?
can the information be used to explain a real life phenomenon?
Validity - how likely is it that the independent variable influenced the dependent
variable? (Alternatively, you can look at ecological validity, which refers to how
closely the study resembles real life - personally I find this easier.)
what other variables were present?
(was it a lab, field or natural experiment?)
(are the activities carried out in the experiment something the participants
would do in their everyday lives?)
(how familiar were the participants with the environment the study was
conducted in?)
Ethics - did the researches stick to the ethical guidelines?
did participants give informed consent?
could participants be at risk of psychological harm as a result of the
experiment?
were participants deceived during the study?
Example of how to evaluate the biological approach:
The methods used by the biological approach give its studies a high degree
of reliability, validity and scientific credibility, which is enhanced by its focus
on objectively observable phenomena rather than subjective experiences.
An objection to the biological approach would be its use of animal models
as a basis for understanding human behaviour: given that each animal’s
nervous system reflects its unique evolutionary niche and history, it might not
be possible to draw clear conclusions about human behaviour from studies of
other animals.
Outline and explain two advantages and two disadvantages of using this
approach to explain human behaviour.
Activity 7: Is behaviour influenced by our nature or our
nurture?
1. Watch the following Ted talk ‘human nature and the blank slate’ by Steven
Pinker and write notes on the influence that nature and nurture have on
behaviour.
https://www.ted.com/talks/steven_pinker_chalks_it_up_to_the_blank_slate
2. Read the information on the nature/nurture debate below.
3. Conduct independent research into at least two behaviours (i.e aggression,
schizophrenia etc.) that are mainly due to nature and two behaviours that are
predominately influenced by nurture.
The nature versus nurture debate is one of the oldest philosophical issues within
psychology. So what exactly is it all about?
Nature refers to all of the genes and hereditary factors that influence who we
are—from our physical appearance to our personality characteristics.
Nurture refers to all the environmental variables that impact who we are,
including our early childhood experiences, how we were raised, our social
relationships, and our surrounding culture.
Even today, different branches of psychology often take a one versus the other
approach. For example, biological psychology tends to stress the importance of
genetics and biological influences. Behaviourism, on the other hand, focuses on the
impact that the environment has on behaviour.
In the past, debates over the relative contributions of nature versus nurture often
took a very one-sided approach, with one side arguing that nature played the most
important role and the other side suggesting that it was nurture that was the most
significant. Today, most experts recognize that both factors play a critical role. Not
only that, they also realize that nature and nurture interact in important ways all
throughout life.
A Closer Look at the Nature vs. Nurture Debate
Empiricists take the position that all or most behaviours and characteristics result
from learning. Behaviourism is a good example of a theory rooted in empiricism. The
behaviourists believe that all actions and behaviours are the results of conditioning.
Theorists such as John B. Watson believed that people could be trained to do and
become anything, regardless of their genetic background.
Examples of Nature vs. Nurture
For example, when a person achieves tremendous academic success, did they do
so because they are genetically predisposed to be successful or is it a result of an
enriched environment? If a man abuses his wife and kids, is it because he was born
with violent tendencies or is it something he learned by observing his own parent's
behaviour?
One example of an empiricist theory within psychology is Albert Bandura's social
learning theory. According to the theory, people learn by observing the behaviour
of others. In his famous Bobo doll experiment, Bandura demonstrated that children
could learn aggressive behaviours simply by observing another person acting
aggressively.
Even today, research in psychology often tends to emphasize one influence over
the other. In biopsychology, for example, researchers conduct studies exploring how
neurotransmitters influence behaviour, which emphasizes the nature side of the
debate. In social psychology, researchers might conduct studies looking at how
things such as peer pressure and social media influence behaviours, stressing the
importance of nurture.
How Nature and Nurture Interact
What researchers do know is that the interaction between heredity and
environment is often the most important factor of all.
In psychopathology, many psychologists argue that both a genetic predisposition
and an appropriate environmental trigger are required for a psychological disorder
to develop; this is set out in the diathesis-stress model. The diathesis is the biological
vulnerability such as being born with a gene that predisposes you to develop a
disorder. However, the disorder will only develop if there is an environmental
‘stressor’ to trigger it. Evidence to support the diathesis-stress model comes from the
Finnish Adoption Study, which compared 155 adopted children whose biological
mothers had schizophrenia, with a matched group of children with no family history
of schizophrenia. The researchers also assessed the quality of parenting through
questionnaires and interviews. They found that the group with schizophrenic mothers
had a 10% rate of schizophrenia, but they also discovered that all of the reported
cases of schizophrenia occurred in families rated as ‘disturbed’. When the family
environment was rated as ‘healthy’, even in the high-risk sample (mother with
schizophrenia), the occurrence of schizophrenia was well below the general
population rates. However, the environment was not the sole cause, as the low-risk
children from ‘disturbed’ families did not develop schizophrenia – so the
environment alone was not enough to trigger the disorder. This research provides
strong evidence that schizophrenia is best explained by looking at an interaction
between genetic inheritance and environmental triggers, in this case, family
environment.
Activity 7 Student Work: Include details of your
research findings in the space below.
Activity 8: Are we more than our atoms?
1. Watch the TED TALK - are you more than your atoms?
https://www.youtube.com/watch?v=fbU9l46Lz7c
2. Read through the information on holism and reductionism.
3. If psychology is considered a science, is psychology inherently reductionist
or holistic? Write half an A4 page justifying your answer.
1. Reductionism & Levels of Explanation: Reductionism is the belief that human
behaviour can be explained by breaking it down into simpler component parts.
Those who take a reductionist position believe that the best way to understand
behaviour is to look closely at the parts that make up our systems, and then use the
simplest explanations to understand how they work. Reductionism is based on the
scientific assumption of parsimony: the idea that complex phenomena should be
explained in the simplest terms possible. Parsimony is similar to the idea of Occam’s
Razor, which was established by William of Ockham in the 14th century. Like
parsimony, this theory states that one should not make unnecessary assumptions
and that the answer to a problem is often the simplest.
2. Holism: Holism comes from the Greek word ‘holos’, which means ‘all’, ‘whole’ or
‘entire’ and is the idea that human behaviour should be viewed as a whole
integrated experience, and not as separate parts. Gestalt psychology adopts a
holistic approach to perception: when we perceive something in the real world, we
do so as a whole rather than as a collection of bits and pieces. What we see only
makes sense when we consider the whole image, rather than the individual
elements that make up our vision. Consequently, some cognitive psychologists also
take a holistic approach. For example, within the area of perception, visual illusions
demonstrate that humans perceive more than the sum of the sensations on the
retina. (If you examine the image on the right, what you will instantly perceive is the
outline of a cube. However, there is in fact no cube in the image and your mind has
created a cube due to the position and configuration of the black shapes).
Activity 8 Student Work: If psychology is considered a
science, is psychology inherently reductionist or
holistic? Write half an A4 page justifying your answer.
Activity 9: Understanding the idiographic versus the
nomothetic approach
1. Read the definitions for the idiographic approach and the nomothetic
approach.
2. Read the evaluations given and decide whether each paragraph has
followed the PEEL structure (Point, Evidence, Explanation and Link).
3. For the evaluation paragraphs that have not followed this structure, re-write
the evaluation paragraph so that it follows the PEEL structure.
1. The Idiographic Approach:
The term ‘idiographic’ comes from the Greek word ‘idios’, which means ‘own’ or
‘private’. Psychologists who take an idiographic approach focus on the individual
and emphasise the unique personal experience of human nature. This means they
favour qualitative research methods, such as the case study, unstructured interviews
and thematic analysis which allow an in-depth insight into individual behaviour. The
idiographic approach does not seek to formulate laws or generalise results to others.
2. The Nomothetic Approach:
The term ‘nomothetic’ comes from the Greek word ‘nomos’ which means ‘law’.
Psychologists who take a nomothetic approach are concerned with establishing
general laws, based on the study of large groups of people, and the use of statistical
(quantitative) techniques to analyse data. This means that experiments,
correlations, psychometric testing and other quantitative methods are favoured
among nomothetic researchers.
Evaluation paragraph example of PEEL structure
Point: There are numerous strengths of taking an idiographic approach, and
a case study method is a powerful tool for evaluating psychological theories.
Evidence: The case of Patient KF (Shallice and Warrington, 1970) exposed a
limitation of the Multi-Store Model of Memory, by providing evidence that our
STM comprises of at least two components (auditory and visual memory) and
not one, as stipulated by Atkinson and Shiffrin.
Explanation: Consequently, a single case study can generate further research
into a particular phenomenon (e.g. memory), which contributes to the
development of new theories that further our understanding of human
behaviour.
Link: Therefore it is evident that taking an idiographic approach can enhance
the understanding of certain psychological fields and thus its use should be
encouraged within the psychological community.
Evaluation paragraphs - Read the evaluations paragraphs and decide whether
each paragraph has followed the PEEL structure (Point, Evidence, Explanation and
Link). For the evaluation paragraphs that have not followed this structure, re-write
the evaluation paragraph so that it follows the PEEL structure.
While case studies can highlight a flaw in psychological theories and prompt
further research, the case study method and other qualitative methods are
extremely time-consuming. Freud’s case study of Little Hans consists of almost
150 pages of verbatim quotes from Little Hans’ father, as well as detailed
descriptions of the events in Little Hans’ life. Freud did go on to create universal
theories of personality development during childhood; however, these were
based on limited and unrepresentative case studies that many psychologists
would discredit.
As nomothetic approach is viewed as scientific, it is useful for predicting and
controlling behaviour. For example, biological psychologists take a
nomothetic approach when explaining obsessive-compulsive disorder (OCD)
and claim that OCD is caused by higher levels of dopamine and lower levels
of serotonin. Drug therapies such as SSRIs are developed on the basis of
nomothetic research and work by redressing a biological imbalance (Soomro
et al., 2009). SSRIs are used to treat OCD and increase the availability and
uptake of serotonin, thus reducing the anxiety associated with OCD, which
helps to improve the lives of people suffering from this condition.
Holt (1967) argues that the ideographic/nomothetic distinction is a false
distinction. Many approaches in psychology take advantage of both
approaches and therefore the two approaches can be viewed as
complementary rather than contradictory. For example, while cognitive
psychologists typically take a nomothetic approach and create general laws
of cognitive processes (e.g. the Working Memory Model), they also take
advantage of the idiographic approach when using case studies to provide
evidence for a particular theory (e.g. Patient KF, Shallice and Warrington,
1970). In reality, many research studies make use of both approaches, and it
could be argued that the distinction between idiographic and nomothetic is
meaningless and that psychologists should employ both methods depending
on the nature of the research question.
Activity 9 Student Work: For the evaluation paragraphs
that have not followed this structure, re-write the
evaluation paragraph so that it follows the PEEL
structure. Use the space below.
Activity 10: Should we be carrying out ‘socially sensitive’
research?
3. Read through the information on socially sensitive research.
4. Some psychological research is considered socially sensitive, research one
socially sensitive study published within the last 20 years (you can select any
study as long as it links to psychology).
5. Write half an A4 page explaining why your chosen study is considered socially
sensitive and explain whether you think that the knowledge gained from that
study justifies it being carried out.
Socially Sensitive Research Sieber and Stanley (1988) used the term social sensitivity
to describe studies where there are potential social consequences for the
participants or the group of people represented by the research. Sieber and Stanley
(1988) identified four aspects in the scientific research process that raise ethical
implications in socially sensitive research:
1. The Research Question: The researcher must consider their research question
carefully. Asking questions like ‘Are there racial differences in IQ?’ or ‘Is intelligence
inherited?’ may be damaging to members of a particular group.
2. The Methodology Used: The researcher needs to consider the treatment of the
participants and their right to confidentiality and anonymity. For example, if
someone admits to committing a crime, or to having unprotected sex if they are HIV
positive, should the researcher maintain confidentiality?
3. The Institutional Context: The researcher should be mindful of how the data is
going to be used and consider who is funding the research. If the research is funded
by a private institution or organisation, why are they funding the research and how
do they intend to use the findings?
4. Interpretation and Application of Findings: Finally, the researcher needs to
consider how their findings might be interpreted and applied in the real-world.
Could their data or results be used to inform policy?
Activity 10 Student Work: Write half an A4 page
explaining why your chosen study is considered
socially sensitive and explain whether you think that
the knowledge gained from that study justifies it being
carried out.
