Q

What is the James-Lange theory of emotion?

A

Stimuli elicit physiological responses and behaviours.
Feedback from the organs and muscles involved organises how we feel emotion (the greater the physiological response, the greater the emotion)

Q

When looking at veterans with spinal injuries, what did Hohman (1966) find?

A

Decreased experiences of feeling anger, sexual excitement, fear and ‘overall feelings’. The more extensive the disruption, the greater the decrease in emotional feelings. Data supports* the view that disruption of the autonomic
nervous system causes changes in experienced emotional feelings

Q

What us the Schachter-Singer theory of emotion?

A

suggests that emotional experiences are based on two factors
(1) physiological arousal
(2) cognitive label.
One of the first theories to bring in a cognitive component, e.g., cognitive appraisal, setting the direction for many future models of emotion

Q

Findings of the study that put people in different irritating situations an with/without norepinephrine to see how they felt

A

Participants interprets physical sensations either as emotional arousal and joins in with euphoric or angry behaviours, OR interprets them as side effects and does not engage

CONCLUSION: Emotions are the result of the interaction between physiological arousal and cognitive interpretation.

Q

What do people with anxiety show in brain activity with mood regulation networkd?

A
  • recruited regulatory network less than participants without mood/anxiety conditions
  • increased activation in areas associated with emotional experience and areas that help compensate for emotions
  • problems in regulating the downregulation of negative emotions and downregulation and upregulation of positive emotions

Q

How do SSRIs help depression/anxiety?

A

24
Q

ow does the process model of emotion approach emotional regulation?

A

treats each step in the emotion generative process as a potential target for emotion regulation

25
Q

d: emotional awareness

A

The ability to identify your own and other people’s emotions

26
Q

d: emotional contagion

A

fast automatic responses to emotional expressions in another person - the precursor to affective empathy

27
Q

d: empathy

A

feeling and experiencing what another person is feeling

28
Q

d: affective empathy

A

Feeling what another person is feeling through recognition, being sensitive and having an appropriate affective response

29
Q

d: cognitive empathy

A

Recognizing and understanding that another person is feeling something different to what you are feeling

30
Q

d: parallel responses to emotion

A

where the observer shares the target’s emotions/feelings

31
Q

d: reactive responses to emotion

A

where we have our own, independent reaction to another’s emotions

32
Q

Difference between parallel and reactive responses to emotion

A

Parallel empathy refers to mere replication of another’s affective state, whereas reactive empathy exhibits greater cognitive awareness and may lead to incongruent emotional responses

33
Q

d: sympathy

A

the awareness and sensitivity to others emotions without feeling the same thing as them

34
Q

Which areas of the brain are responsible for what types of empathy?

A

cognitive/effective empathy - ventromedial prefrontal cortex (vmPFC) supramarginal gyrus and anterior dorsal medial frontal gyrus
emotional/parallel/affective empathy - inferior frontal gyrus or posterior dorsal medial frontal gyrus

35
Q

d: prosocial motivation

A

The intention to respond compassionately to another person’s distress

36
Q

what are the sex differences in empathy?

A

Significant sex differences for all components of affective empathy, small differences between sexes evident in cognitive empathy. Women showed greater empathy

37
Q

what differences are there in the congenitally and non-congenitally blind athletes compared to sighted athletes in emotional expression?

A

very few differences - suggests that emotion expression is innate and does not require learning by imitation.

38
Q

within speech recognition, are positive/negative emotions universal or cultural?

A

Negative emotions have vocalisations that can be recognised across cultures, but positive emotions are communicated with culture- specific signals

39
Q

are facial expressions innate or culture-specific?

A

Facial expressions of emotion are culture specific, refuting the hypothesis that human emotion is universally represented by the same set of six distinct facial expression signals

40
Q

What part of the brain helps in emotion recognition in other’s FACES?

A

right somatosensory cortex

41
Q

what does imitation have to do with emotional recognition?

A

When we see a facial expression of an emotion, we unconsciously imagine ourselves making that expression

42
Q

What is the simulationist hypothesis of emotional recognition?

A

Emotion recognition involves simulation of emotion that we are viewing

43
Q

What parts of the brain help with emotion recognition?

A

left-hemisphere (mainly) of the amygdala and and anterior insula across emotions, but category specific lateralization of the vmPFC

44
Q

Which sides of the Fusiform Face Area/Occipital Face Area do each sex use for face processing?

A

right-sided asymmetry of the bioelectrical activity in males and a bilateral (both) or left-sided activity in females in regions such as Fusiform Face Area, Occipital Face Area or
facial expression processing

45
Q

How does emotion recognition develop with age?

A

Different emotion recognitions develop at different speeds & vocal emotional recognition takes longer

46
Q

How does oxytocin affect emotional recognition of those with antisocial personality disorder?

A

Improvement of the recognition of fearful and happy facial expressions by oxytocin in young adults with ASPD.

47
Q

Are men better at reading, just visual, just vocal or visual and vocal emotional cues?

A

Recognition accuracy was significantly higher in the audio- visual than in the auditory or visual modality

48
Q

How does testosterone influence emotional recognition?

A

A positive association between testosterone and recognition accuracy

49
Q

How does cortisol influence emotional recognition?

A

low cortisol showed better reaction times to emotion and accuracy at recognition

50
Q

d: Alexithymia

A

the inability to recognize or describe one’s own emotions.

51
Q

does alexithymia affect the ability of someone to recognise other’s emotions?

A

The data seem to support the idea that recognising emotions and feelings of other people relies on the ability to identify and recognise correctly one’s own feelings

52
Q

How is the input to the ventromedial prefrontal cortex significant in emotional responses/recognition?

A
  • receives information about what is going on in the environment and what is being planned in the rest of the frontal lobe such as:
  • Thalamus
  • Temporal cortex
  • Ventral tegmental area
  • Olfactory system
  • amygdala
53
Q

How is the output to the ventromedial prefrontal cortex significant in emotional responses/recognition?

A

Outputs affect a variety of behaviours/physiological responses, including emotions organised by the amygdala and other areas such as:
* Cingulate cortex
* hippocampal formation
* temporal cortex
* lateral hypothalamus
* amygdala

54
Q

what happens to behaviour and decision making if there’s damage to the vmPFC?

A

serious impairments of behavioural control and
decision making, associated with emotional/social personality changes

55
Q

which area of the brain is used during moral decision making?

A

vmPFC & temporoparietal junction (TPJ)

56
Q

How do types of dementia (behavioural variant frontotemporal dementia bvFTD vs Alzheimer’s disease vs control) respond to the train moral dilemma?

A

The bvFTD participants were more willing to push a man in order to stop a trolley from killing five other people, than

The bvFTD participants showed less conflict when responding to moral dilemmas, whereas the AD and HC groups expressed distress

57
Q

which area of the brain does behavioural variant
frontotemporal dementia effect?

A

frontal lobe
