Flashcards in W19-L12: Introduction to cognition and emotion Deck (14):
1

Why Study cognition?

Inform diagnoses and to work out how to best work with the patient

2

Localisation of Function

function relationship is one to one

3

example of Lateralisation of function

Left hemisphere for language, right hemisphere for visuospatial

4

Shortcomings of Lateralisation of function

Oversimplification of complex phenomenon as its rare for ‘absolute’ specialisation and there are Individual differences

5

Luria's brain-behaviour theory

Three basic units of the CNS :
1. Regulation of arousal & muscle tone - brainstem and associated areas
2. Reception, integration, and analysis of sensory information
- posterior cortical regions
3. Planning, executing, and verifying behaviour
- frontal and prefrontal lobes

6

Luria's cortical zones

Primary zone for basic information, secondary zone is perception, tertiary zone is integration (only evident in humans)

7

Pluripotentiality

1. Each area of the brain operates in conjunction with other areas
2. No area is singly responsible for voluntary human behaviour
3. Each area may play a specific role in many
behaviours

8

Emotion

an inferred behavioural state

9

core emotions

Innate, anger, fear, sadness, disgust, happiness, (surprise)

10

Complex emotions

involve different combinations of core emotions

11

Klüver-Bucy syndrome

Behavioural syndrome from bilateral anterior temporal lobectomy. Includes tameness or loss of fear

12

Orbitofrontal cortex

Identification and expression of emotion

13

James Lange Theory

We experience emotion in response to physiological changes

14

Cannon Bard Theory

Can experience emotion without expressing it physically eg. in case of spinal cord lesions
