TB4 Lecture 1; Emotion and the Brain quiz

1. When patient SM was asked to rate intensity of emotions in facial expressions what were the findings?

Patient SM could not categorise fear
Patient SM could not categorise anger
Abnormal ratings of fear emotions, some other emotions (e.g anger) were not normal either but fear the worst affected
The emotions of fear, disgust and anger produced abnormal rating

Each emotion is a discrete, independent entity; with the innate basic emotions being fear, sad, anger, surprise, disgust, happiness.
Each emotion is a point represented on a 2D space dfined by the X axis of arousal (low-high) and valence (positive-negative emotions) E.g happy may share the same x as afraid but with differing valence (y)
Each emotion has an assigned physiological response, e.g happiness --> smiling = an increase in dopamine.
The amount of arousal corresponds to which emotion from the innate selection of fear, sad, happy, anger, surprise, digust

Related to valence, there is more eye-blink when feeling fear, and less with happiness. Much faster than SCR.
Related to valence, there is less eye-blink when feeling fear, and more with happiness. Much slower than SCR.

Neurotypical pps don't generally think about 'risky' or 'safe' decisions when making moves
Neurotypical pps even before explicit knowledge of risky moves tend to choose 'safer' decks. Use gut instincts to guide their choices
Neurotypical pps even before explicit knowledge of risky moves tend to choose more risky decks as they can appropriately calculate the outcome. Use gut instincts to guide their choices
Lesions to pre-frontal cortex made participant choose safer decisions

Dimensional; 6 basic emotions seem to be shared cross culturally, pps selected the model with the correct affect for the emotion
Dimensional; Rats responded in the same way to 6 basic emotion related stimuli e.g surprise = all showed the same physiological startle response
Categorical; 6 basic emotions seem to be shared cross culturally, pps selected the model with the correct affect for the emotion
Categorical; Rats responded in the same way to 6 basic emotion related stimuli e.g surprise = all showed the same physiological startle response
