lecture 9- social neuroscience

Question 1

petzel et al 2024 found what

Answer 1

majoirty of pts agreed to wokring for an equality university but when using IAT most had a neutral IAT but one condition

Question 2

what is social neuroscience

Answer 2

using the brain to measure social behavioural processes- allows for measuirng processes before and after

Question 3

what is transcranial magnetic stimulation

Answer 3

non-invasive technique, strong meagnetic coil that slows down electrons and deactivates the cortex. can only do like a global reduction in an area

Question 4

sellaro et al- used what techniques

Answer 4

tDCS and IAT- increased activation means IAt scores go down and less bias equals more self-control.

Question 5

what is magnetic resonance imaging

Answer 5

scans the radio frequencey by hydrogen atoms when they are subjected to a strong magnetic field.

Question 6

cunningham et al used mri to…

Answer 6

when faced with a black face their is an increase in amygdala activation

Question 7

how do outgroups dehumanise ingroup

Answer 7

outgroups are not believed to share basic physical features that characterise the ingroup.

Question 8

what is the ascent-dehuminsation scale

Answer 8

rate social groups from monkesy to humans.

Question 9

what is the limitations of using the ascent-dehuminsation scale as a measure

Answer 9

susceptible to social desirability

Question 10

what is the FFA

Answer 10

fusiform face area- located in termporal lobe, processes facial information

Question 11

dehuminsation severs what bonds

Answer 11

empatehtic bonds people feel for others which truggers indifference and inattention to pain

Question 12

what do we need to engage in order to gain isnight into someones life

Answer 12

the FFA

Question 13

what is an eeg

Answer 13

electroencephalogram- records combined actovoty usign electrodes- good temporal resultion but poor spatial resolution

Question 14

what 4 waves does an eeg measure

Answer 14

delta, alapha, theta and beta

Question 15

what did an eeg find in the difference of motivation

Answer 15

left lobe- greater activity for approach, right lobe- greater activity for avoidance.

Question 16

schiemle et al 2016 foudn what when you approach

Answer 16

your more motivated- use resources to seek things that make you happy.

Question 17

what is an erp

Answer 17

distinct wave patterns within the EEG over time including the perception of stimuli or response to it.

Question 18

what is an error-related negativity?

Answer 18

self deflection that occurs after giving a response, peaks after you realsie you made a mistake

Question 19

what does an ERN mean during an IAT

Answer 19

high in IMS and low in EMS- experience an ERN when they make an error allocating black individuals.

Question 20

petzel et al 2022 found people were less likely to monitor errors…

Answer 20

between black-tool associations by making them tired

Question 21

what is the n170

Answer 21

in depth processing informed by the fusiform area. pitcher et al 2011- found higher amplitude for faces compared with chairs.

Question 22

senholzi and Ito 2013- looked at the n170 duirng…

Answer 22

looked at white or black faces told to either look at them as an indeitiy or category.

Question 23

findings of senholzi and ito 2013’s study

Answer 23

for identity similar amplitude for white and black faces, but when categorising by race higher amplitude for white faces

Question 24

focusing on identity… focusing on category…

Answer 24

promote empathy… promote bias

Question 25

david amodio suggested the top down modulation of the n170 may be…

Answer 25

due to strategic shifts in early attention- identify someone is balck which shifts n170 early on

Question 26

what is the sympathetic-adrenal medullary axis

Answer 26

activates sympathetic nervous system- short term coping mechanism for stress.

Question 27

what is the HPA axis?

Answer 27

release cortisol over the day, we need it to get out of bed.

Question 28

doerr et al 2015- found that under exam conditions HPA axis…

Answer 28

awaken cortisol levels peak in eaxm gives you more resources for stress- constant exams eventually burnout

Question 29

why is high heart rate variability good?

Answer 29

fexible and responsive cardiovascular system, better overall health but low HRV indicate stress

Question 30

what is the battle between SAM axis and vagus nerve

Answer 30

vagus nerve slows things down whilst SAM speed things up when stress hits

Question 31

HRV is importnat because…

Answer 31

shows how good you can regulate emotions- if you can manage fluctuations you can handle stress better and recover more quickly.
