Topic Eighteen - Signal Detection Flashcards
(7 cards)
1
Q
What is response bias and the influence of criterion?
A
2
Q
How does signal detection theory provide a method for separating response bias from sensitivity?
A
3
Q
Can signal detection theory be applied to situations outside of psychoacoustics? If so, what are they?
A
- Yes
For example:
- Medical diagnostics
- Juries
- Screening donated blood for HIV
4
Q
What is internal response?
A
The internal response is the subjective internal value that an observer uses to decide whether a stimulus is present or absent.
5
Q
What is external noise?
A
6
Q
What are probability of occurrence curves?
A
A graph (typically bell-shaped) showing how often different levels of internal response occur under each stimulus condition.
7
Q
What are receiver operating characteristic curves and the discriminatory index?
A
- A receiver operating characteristic is a graph that separates the sensitivity and response bias
