Psychology – Emotional Modelling Joy

Positive feedback, achieving instant peak, decreasing with time

Fear Negative, gradual peak, happening mostly in safe environments

Other feelings Success/failure, danger/safety, expectations, trust, surprise, disgust

and anticipation

Diversity Two individuals never have the same emotional response (they need

to be randomised)

Stereotypical animation Fear: rapid head motion, low posture, bulged eyes Happiness: smiling straightened body, slow and graceful movement

Behaviour Social Learning, relations, self-esteem and anxiety, Mood

modification, Tolerance, Withdrawal Academic performance and crime General Energy and arousal Cognitive model of aggression, Conflict Addiction Catharsis theory (experiencing depictions of violence in

media can reduce aggressive feelings) Cultivation & Stereotyped perception

Player Behaviour: Participants, design, material, procedure,

Decision trees- properties of player behavior, such as reading texts, viewing pictures, or click rates in the game; determine which player behavior corresponds to which class of learning outcome.
