Why is a real psychometric function not a step function?
Detection of Stimulus is always subject to chance
Detection of Stimulus is always subject to noise
It is already a step function
Detection of Stimulus is always subject to Criterion
More false alarms means
Lax criterion
Strict criterion
Larger the d' the
Easier to detect signal
Harder to detect signal
d' is calculated by
z-score of hits - z-score of misses
z-score of hits - z-score of false alarms
z-score of hits - z-score of correct rejections
z-score of correct rejections - z-score of misses
If a d' = 0
The curves are far apart no longer touching
The curves are overlapping
How do you calculate Specificity
Hits divided by all presents
Hits divided by all absents
Correct rejections divided by all presents
Correct rejections divided by all absents
This is described by tongue position "up-down / front-back"
