Question 1

HYP

Answer 1

if amyg really processes threat auto then should precess regardless of attentional focus - so long as cue in periphery

Question 2

pessoa exp 1

METHOD

Answer 2

contrast facial exp when focus of attention vs when irrelevant to focal task

binary choice task: face m/f? or lines same length? - presented together

Question 3

RESULTS

Answer 3

91% correct for faces
64% correct for lines
- sufficiently attending

response of right amyg (v) (processing) hightened to neg valence face
response of left (D) amyg to both pos and neg valence
- ONLY WHEN ATTEND

below threshold when attend to task lines

– when not attending - there is NO amyg response to threat faces (OPPOSES WHALEN)

Question 4

eval of pessoa exp 1

Answer 4

using BOLD mri response
blood flow - slower than neuronal activity
**ICMS
may be that the fast, rapid neural response not detected in blood because differential to explicit processes - inhibited before explicit

Question 5

definition issue of automaticity

Answer 5

psych: without awareness, has to be mandatory (no matter what)

PESSOA: processing not auto because not mandatory - not activated across all task paradigms

Question 6

whalen replication

Answer 6

backwards masking

found robust amg at 67ms (explicit) but not 33ms (implicit)

Question 7

szszpanowski and pessoa

individual differences

Answer 7

found some individuals can detect at an above chance level to the fear faces presented at 17ms

differences in sensitivity to detect
- whalen may be driven by these? - bias in sample
