- Discrimination
- Stimulus generalization is when an animal learns
to make the same response to similar stimuli
- A discrimination is when an animal learns to make
a differential response to two or more stimuli
- In the case below, two generalization gradients
are shown. The solid line indicates responses to a
single stimulus and to other similar stimuli
- Note that the training stimulus is where the
highest level of response takes place
- As one goes in either direction away from the
training stimulus response level is less
- Peak Shift
- In the peak shift example (see dotted line), two
stimuli are used.
- One stimulus is associated with reward (the
SD)the other (the SD) with no reward
- Notice how the point of maximum response is now
shifted AWAY from the SD
- Also notice how the generalization gradient is
steeper in this case
