PSYCH 230 - EXAM 1 (UIUC)method of adjustment (observer adjusts)
participant controls the level of stimulus, adjusting stimulus to reach a threshold
or match something
sensitivity
no sensitivity: can't hear anything
moderate sensitivity: some difference (shower on, phone just outside bathroom
with door open)
high sensitivity: no mistakes, you can hear it perfectly
magnitude estimation
participants judge and assign numerical estimates to perceived stregnth of a
stimulus
stevens' power law
a principle being the perceived magnitude of a stimulus describing the
relationship between intensity of the actual stimulus and a constant raised to an
exponent
Catch trials and their use
,to detect no false reporting in a trial, presenting no stimulus to see how
participant responds
Signal Detection theory
intensity of the stimuli and the individual's psychological and physical state
contributing to whether they can detect the stimuli or not
Criterion
point at which you respond to a signla or don't
d-prime
how different the signal (shower) is from the noise (ringtone)
ex: d-prime is low when there is little difference in sound of shower and ringtone,
d-prime is high when ringtone is dog barking to sound of shower
changes in criterion
shift to left= value smaller and the observer will respond that the signal is present
more of the time (more false alarms)
shift to right= value is larger and the observer will be less likely to respond that
the signal was present (more correct rejections)
Touch
sense of touch includes a variety of sensations
, thermoreceptors
sensory receptors that signla information about temperature
mechanoreceptors

and itch)
