Q

Theories of emotion

James- lange:

A

The stimulus causes arousal in the autonomic nervous system, this change causes the conscious feeling of being scared.

A

emotional experience and expression are parallel processes and have no direct causal relationship

“i feel afraid and i tremble”

3

All three things integrate to create emotion: - the perception of emotion stimulus, the activation of the ANS and SNS and the experience of emotion.
Appraisal.

Q

Phillip Bard

Sham rage

A

Cats whose cerebral hemispheres have been removed down to but not including the hypothalamus.

It is not elicited if the hypothalamus is removed too.

  • Bard concluded that the hypothalamus is critical in the expression of aggressive responses.
  • The function of the cortex is to inhibit and direct these responses.
5
Q

the limbic system

A

Is a collection of nuclei and tracts that borders the thalamus,

  • the amygdala
  • the mammillary bodies
  • the hippocampus
  • the fornix
  • the cortex of the cingulate gyrus
  • septum
  • olfractory bulb
  • hypothalamus
6
Q

what is Kluver Bucy syndrome ?

A

Bilateral lesions of the medial temporal lobes (including the amygdala).
No fear, increased sexual drive but towards inappropriate objects,

  • Monkeys who have their anterior temporal lobes removed most of the symptoms appear just from amygdala damage.
7
Q

what can be used to measure emotions

A

polygraph

8
Q

the facial feedback hypothesis

A

putting on a happy face does make you feel better.

9
Q

EMG

A

detects facial movements

genuine smile = Duchenne smile

10
Q

FEAR conditioning

A

The establishment of fear in a previously neutral stimulus

  • little albert
  • rats receive a tone and electric shock
11
Q

The medial geniculate nucleus (The relay nucleus of the thalamus)

A

lesions to this area will block fear conditioning of a tone

lesions to the auditory cortex does not

  • the pathway to the amygdala
12
Q

the amygdala

A

lesions to the amygdala block fear conditioning
the amygdala receives all input from sensory systems and significance is retained
it is a cluster of nuclei

  • The perception not the production of fear
13
Q

contextual fear conditioning

A

the context alone is enough to elicit a fear response

- involves the hippocampus

14
Q

Individual differences

- Differences between people

A

personalities could cause poeple to respond differently to emotions

15
Q

PAtient SM (Amygdala removed)

A

cant recognise the emotion of fear when presented with faces .

16
Q

Autism and emotions

A

could involve the amygdala because they have trouble recognising emotions

17
Q

Psychopaths

A

could have different amygdala because they have trouble recognising emotions

18
Q

hypothalamus

A

The expression of fear.
- the cortex inhibits and directs these responses

Sham rage

19
Q

the amgydala

A

the perception of fear.

Kluver bucy syndrome
