Q

What is threshold in psychophysics? (S&P Cognitive)

A

Change from one perception to another

17
Q

What is absolute threshold in psychophysics? (S&P Cognitive)

A

Smallest stimulus intensity needed for detection

18
Q

What is differential threshold in psychophysics? (S&P Cognitive)

A

Smallest difference between 2 stimuli that can be detected

19
Q

What two ways can thresholds be measured in psychophysics? (S&P Cognitive)

A

1) Method of adjustment

2) Forced choice procedure

20
Q

What is method of adjustment in psychophysics? (S&P Cognitive)

A

Gradually change intensity of stimulus until it can no longer be detected

21
Q

What is forced choice procedure in psychophysics? (S&P Cognitive)

A
  • Give two options and ask which one holds the stimulus

- Change intensity on trails

22
Q

What is introspection? (S&P Cognitive)

A

The observation of ones own mental and emotional processes
