Psychology / Unit 5 Psych 0515 short lesson, about 20 seconds
Stimulus Discrimination
Captions available
The idea
Stimulus discrimination is responding to the conditioned stimulus and not to similar stimuli that were never paired.
In practice
A dog trained with only one tone followed by food stops responding to the neighboring tones.
Where people slip
Discrimination requires the similar stimuli to occur without the unconditioned stimulus. Absence of pairing is the teacher.
