|
Method of constant stimuli |
Many stimuli, ranging from rarely to almost always perceivable, are presented one at a time |
|
|
Method of limits |
The magnitude of a single stimulus or the difference between two stimuli is varied incrementally until the participant responds differently |
|
|
Method of adjustment |
Similar to the method of limits, but the participant controls the stimulus directly |
|
|
Method of estimation |
The participant assigns values according to perceived magnitudes of the stimuli |
|
|
Cross Modality matching |
The participant matches the intensity of a sensation in one sensory modality with the intensity of a sensation in another |
|
|
Signal detection theory |
A psychophysical theory that quantifies the response of an observer to the presentation of a signal in the presence of noise. |
|
|
Sensitivity |
A value that defines the ease with which an observer can tell the difference between the presence and absence of a stimulus or the difference between stimulus 1 and stimulus 2 |
|
|
d' |
how discriminable the two signals are (the difference between the means) |
|
|
Doctrine of specific nerve energies |
A doctrine formulated by Johannes Müller (1801–1858) stating that the nature of a sensation depends on which sensory fibers are stimulated, not on how the fibers are stimulated |
|
|
Light |
a narrow band of radiation that can be conceptualized as a wave or stream of photons |
