Q

What kind of response do we see with potential?

SCRrecovery half time/rise time
17
Q

List 3 potential metrics

A

SPL

18
Q

What are four sensitive areas when considering EDA response to a stimulus?

If you want to measure the effect of one, the others have to be controlled.

A

novelty
emotional content
intensity
significance

If you want to measure the effect of one, the others have to be controlled.

19
Q

Fixed vs. variable signal schedules: which one showed lower phasic and tonic skin conductance?

A

Variable

20
Q

Labile have ____
Stabiles have _____

They reckon stabiles have lower ______

A

Labiles: high SPRs
Stabiles: low SPRs

They reckon stabiles have lower resting sympathetic tone.

21
Q

Labiles have more ___, ___ and ___ and faster reaction times.

A

SPR, SCR, SCL

22
Q

Based on sympathetic activity - sympathetic arousal is associated with increase/decrease in SC?

A

Increase

23
Q

T or F

Negative affective stimuli increases SCR, but positive or neutral stimuli have no effect.

A

True.

24
Q

Shorter SCL recovery half time is associated with…

A

… goal orientedness AND being in the middle of a goal oriented activity.

25
Q

High SPRs before a signal are better or worse for detection?

A

Better.

26
Q

Low SPRs in the 18s before a signal is better or worse for signal detection?

A

Better.

27
Q

SPRs relating to signal detection - we’re talking on the order of seconds/minutes/hours surrounding the signal?

A

about 18s

28
Q

What’s the difference between SCR magnitude and frequency when it comes to vigilance?

A

frequency: better detection
magnitude: fewer errors

29
Q

SCR frequency or magnitude: which is a better indicator of attention level?

A

MAGNITUDE.

higher magnitude = higher accuracy.

30
Q

How do we tell if the face of a Russian mobster is familiar to Donald Trump or not?

A

Higher SCRs will show on his skin.

31
Q

What famous phenomenon was illuminated with EDA to do with face recognition?

A

PROSOPAGNOSIA people showed EDA to familiar people’s faces even through they didn’t consciously recognise them.
Visual memory is still intact to the autonomic system.
“Autonomic discrimination without awareness”.

32
Q

Why is EDA a good measure for understanding conditioning responses?

A

Because something like HR depends on cognitive processing.

EDA reflects autonomic responses that don’t depend on conscious recognition and appraisal.
