Signal detection theory holds that detection of a stimulus depends on
- A
Absolute threshold values alone, regardless of motivation or expectation states
- Bcheck_circle
Both sensory factors AND decision criteria (motivation, expectations)
- C
Sensory receptor sensitivity and stimulus intensity only, with no other factors
- D
Random chance and statistical noise in the perceptual decision-making process
Explanation
Different observers have different "criterion" levels — same signal, different responses.
