Q

Why is the study of cognition important for practice?

A

Can inform diagnoses

Can help us to determine how best to work with patients, based on their abilities

Q

What is it important to remember when considering localisation and lateralisation of function?

A

It is rare for ‘absolute’ specialisation to occur, and that individual differences exist

Q

Briefly describe Luria’s brain-behaviour theory?

A

There are three basic units of the CNS, each specialised for different funtions

Q

What are the three basic units of the CNS described by Luria?

A

Brainstem and associated areas
Posterior cortical regions
Frontal and prefrontal lobes

20
Q

Which functions did Luria associate with each of the three units of the CNS?

A

Brainstem and associated areas: regulation of arousal and muscle tone
Posterior cortical regions: reception, integration, and analysis of sensory information
Frontal and prefrontal lobes: planning, executing and verifying behaviour

21
Q

Describe Luria’s cortical zones?

A

Three divisions (primary, secondary and tertiary zones) in the anterior and posterior cortical regions

22
Q

What is the problem with Luria’s brain-behaviour theory?

A

Some cognitive domains do not have one-to-one structural relationships;m need to think of systems or networks for each cognitive domain

23
Q

Describe Luria’s principles of functional systems, or ‘pluripotentiality’?

A
  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
24
Q

Describe Darwin’s early ideas about emotions?

A

Basic emotions have adaptive significance

Humans share emotional states with animals

25
Define emotion?
SEVERAL DEFINITIONS: Inferred behavioural state - conscious, subjective, internal feeling Psychophysiological state - incorporates conscious feelings - physiological arousal - cognitive component
26
What are the core emotions?
``` Anger Fear Sadness Disgust Happiness (Surprise) ```
27
What are the important characteristics of core emotions?
Culturally universal Innate Involve 'old brain' structures
28
How do complex emotions arise?
Different combinations of core emotions
29
Which emotions are most frequently used in research and why?
Fear and sadness They are easy to elicit and study They correlate with anxiety and depression
30
Which neural systems are involved with emotion?
Limbic system
31
What is the limbic system composed of?
``` Hippocampus Cingulate gyrus Hypothalamus Amygdala Septal area Nucleus accumbens Orbitofrontal cortex ```
32
When does Kluver-Bucy syndrome arise?
Damage to anterior temporal lobe, in particular the amygdala
33
Describe the presentation of Kluver-Bucy syndrome?
Tameness | Loss of fear
34
What does Kluver-Bucy syndrome indicate about the function of the amygdala?
Involved in implicit emotional learning
35
What is the function of the orbitofrontal cortex?
Identification and expression of emotion
36
What do lesions to the orbitofrontal cortex result in?
Reduced facial expression and affect
37
Describe the laterality effect of orbitofrontal cortex lesions?
Right lesions worse than left lesions
38
Describe the findings about OFC in patients with affect disorders?
Reduced OFC volume
39
Describe the link between the hippocampus and affective disorders?
Volume reduction in depression
40
Describe the James Lange Theory of cognition and emotion?
We experience emotion in response to physiological changes
41
Describe the Cannon Bard Theory of emotion?
We can experience emotion without expressing it physically | Physiologic changes are not unique to specific emotions
42
What is the core of the primacy debate?
Is cognition essential to experiencing an affective response? ie. does emotion precede cognition or vice-versa?
43
Describe Lazarus' idea of cognitive appraisal and emotions?
'What you bring to a situation will impact the outcome' Cognitive processing is integral to emotional states, and cognitive appraisal directly impacts the physiological stress response Cognitive appraisal can influence the type of emotional response
44
Describe the idea behind psychological interventions for mental health disorders?
Cognitive appraisal: change they way you think > change the way you feel Reduce physiological response and tackle cognitive underpinnings
45
What is cognitive appraisal?
Personal interpretation of a situation
