VERSION!!
Psychophysics - CORRECT ANSWER-the study of the relationship
between the physical variables of environmental events/objects and the
sensation and perception that they elicit
cross-modality - CORRECT ANSWER-Integration between senses, ex:
how vision affects hearing
Objective tests (definition and examples) - CORRECT ANSWER-factual
tests regarding what a listener can hear
,- ex: detection, discrimination, recognition
Subjective tests (definition and examples) - CORRECT ANSWER-tests that
are more personal to the listener, what they do hear
- ex: sensory scaling, matching
Detection task - CORRECT ANSWER-change from stimulus to no stimulus
Discrimination task - CORRECT ANSWER-telling the difference between
two stimuli
absolute threshold - CORRECT ANSWER-The stimulus amplitude that an
observer can barely detect
difference threshold - CORRECT ANSWER-The minimum change from a
constant stimulus parameter value that produces a noticeable perceptual
difference
, Method of Constant Stimuli - CORRECT ANSWER-Test is looking to
determine the thresholds for signal detection in noise
- A set of signal levels are selected. The signal level varies randomly from
trial to trial, while the noise level is fixed. In each trial, the listener indicates
if he or she detects the signal (yes or no).
psychometric function - CORRECT ANSWER-Relate a measure of
listener's performance (e.g., percent of time that a stimulus is detected) to a
measure of the stimulus (e.g., stimulus intensity level).
How is threshold in a psychometric function determined - CORRECT
ANSWER-chosen by the experimenter, usually 50%
response bias - CORRECT ANSWER-anything in a survey design that
influences responses, ex expectations, difference in instructions, tendency
to over- or under-respond
hit, miss, false alarm, correct rejection - CORRECT ANSWER-hit = saying
yes when stimulus is present
