emotion pt2 Flashcards
how do we communicate emotions, 3
changes in posture, facial expressions
non verbal sounds
what did charles darwin say about emotional expressions
innate and biologically determined
what do cross cultural studies of emotion show and conclusion
people in new guniea tribe could recognise western emotional expressions
westerners could recognise tribesman facial expressions
conclusion- expression of emotions are unlearned as they’re same in other cultures that havent been exposed to each other
visually impaired study support for innate emotional expression
facial expressions of blind children are similar to those of sighted children
few diffs in emotional expressions of blind from birth, blind and non blind athletes at 2004 paralympics
emotion expression is innate and doesn’t require learning by imitation
how does emotion expression change in group situations
more pronounced
kraut and johnston study (group emotion expression)
small signs of happiness when alone
more likely to smile in social situations
jones et al study (infants smiling in front of others)
smiling increases in the presence of others from age of 10 months
tracy and robins study (is emotion recognition automatic)
pts could accurately recognise emotion of facial expressions even if only presented for brief time
more time to view images, classification of emotion showed little improvemnt
suggests we recognise other peoples facial expressions automatically, fast and accurately
in what instance is body language easier to recognise
when facial expression and body language is congruent
which hemisphere seems to play more of role in emotion recognition and support (george et al)
right
pts listened to sentences with emotional content, listened to meaning of words and tone of voice
found meaning of words- bilateral activation of prefrontal
tone of voice- right lateralised activation of prefrontal
what is the role of the amygdala in facial recognition of emotion
role in emotional responses and recognition, especially fear
amygdala is activated with scary stimuli, fearful faces and body postures of fear
activity is quicker than concious visual processing
what happens with amygdala lesions and emotion recognition
results in issues recognising emotion in facial expressions
fear is especially impaired
what is the simulationsit hypothesis
how imitation plays a role in emotional recognition
emotion recognition invloves simulation of emotion we are viewing
adolphs et al study (emotional recognition and imitation) and interpretation
pts with poorest facial emotion recognition had damage to RIGHT somatosensory cortex
interpretation when we see facial expression of an emotion, we unconciously imagine ourselves making the expression
2 evidence for simulationist hypothesis of emotion recognition
neuroimaging- brain regions activated when observing emotion are similar to regions activated when making emotional expressions
transcranial magnetic stimulation TMS- disruption to vidual areas and somatosensory areas imapaired peoples ability to recognise emotional expressions
