Q

Introverts have ____ levels of activity in the ARAS, causing them to seek ____ _______ of stimulation.
Extraverts have _____ levels of activity in the ARAS, causing them to seek situations with ____ stimulation

A

Introverts - over-active ARAS - causing them to seek low levels of stimulation

Q

Wright et al found extraversion was ___________ correlated with cortical thickness in pre-frontal regions, suggesting what for the PEN theory?

A

extraversion negatively correlated with cortical thickness in pre frontal regions
not necessarily supporting PEN theory of ARAS activation

24
Q

Other than the lack of support for regions Eysenck identified in the PEN theory, were three other issues with Wright et al (2006) structural MRI study?

A

small sample size
reliability of measures
gender distribution

Q

Describe Grays RST theory - what is personality?

differences in personality due to extents to which people respond to rewards and punishment
different people have different reactivity to stimuli and situations

26
Q

People who are more sensitive to rewards learn faster with ______ stimuli, and people more sensitive to punishments learn faster with ______ stimuli

A

Reward-sensitive people learn faster with pleasant stimuli
