week2-judging actions of others Flashcards
what is kinematics
kinematics is “style” of movement: speed, acceleration, jerk
Kinematics suggest intention = cite describe one study
Soriano et al 2019 - people can infer intention of drinking from a bottle based on their kinematics before the bottle is grabbed.
Kinematics change according to emotional states study
Roether et al 2009 - participants correctly recognised anger in fast point light walkers and sadness to slow gait in those walkers
2 Studies suggesting a biased view of others emotional states based on their kinematics
People that tend to walk faster judged angry stimuli as less angry compared to slow walkers - Edey et al 2017
People level of confidence influences how confident they judge another person based on their kinematics = people with faster kinematics may judge others as less confident since fast movement is typically associated with greater confidence = Patel et al 2012
Individual differences that can influence kinematics
autism = problem with theory of mind (baron Cohen 1985) and different kinematics (cook 2013) = suggest a link between reading emotions/social skills and kinematics.
which neural network is involved in observing actions describe with one ref, and cite another study supporting the associative learning view for this
same regions are activated during observing and performing actions = the mirror neuron system in VENTRAL PREMOTOR CORTEX = Locoboni et al 1999
Press et al 2012 = this is seen even when observing and performing actions involving random stimuli/non-human thus does not support evolutionary claim = social experience more important
Quiro-Ramirez 2015
Cultural factors influence emotion inferences in others = europeans are better at detecting emotions of europeans vs asian .
What cortical regions are involved when people observe unexpected actions and what does it suggest
Medial Prefrontal cortex is activated when people observe a person performing unexpected action with no activation of motor region = suggest that MPC is involved in inferring intentions = Brass et al 2007
What can we conclude overall abt the neural networks at play
There seem to be a social brain involved in inferring intentions/internal states in MPC and during this motor areas are less distinctly involved but does not mean they are not involved at all. - gallhager & frith 2003.
