Exam 6: Generalization and Discrimination Learning

Suppose researchers train a rat to press a bar when a 1,000 Hz tone sounds and that you train the same rat to NOT press the bar when a 1,200 Hz tone sounds.Finally,they test for generalization using the following sounds: (a)900 Hz, (b)1,000 Hz, (c)1,100 Hz,and (d)1,200 Hz.Draw a graph showing the excitatory and inhibitory gradients and the summation curve showing the peak shift.

Lesions of the hippocampal region lead to:

If we lesion the primary auditory cortex of a cat,the generalization gradient:

In a ______ representation,nodes or neurons responding to physically similar stimuli are near each other.

Draw a generalization gradient that would occur for a yellow light before discrimination training.On the same graph,draw a generalization gradient that would occur for a yellow light after discrimination training.

If we use a red light and a blue light as our stimuli in a negative patterning task,we would reward responding:

Describe an example of discrimination (as it relates to the study of learning)in your everyday life.

Sienna learned that many vegetables tend to be green in color.When she later learned in school that vegetables are healthy,she inferred that foods that are green are healthy.That she made this inference is an example of:

Freda once became sick after eating pepperoni pizza.Based on the idea of a generalization gradient,which of the following foods would she be MOST likely to avoid in the future?

Explain how stereotyping is related to the concept of generalization.

Which of the following is seen in people with schizophrenia?

Which of the following findings confirms Gluck and Myers's prediction regarding the role of the hippocampus in generalization?

The transfer of past learning to new situations and problems is known as:

Discrete-component representations provide a good description of:

Larry is visiting his grandmother and cooking dinner for her.Since his grandmother has a different model of microwave oven than his,Larry has learned that he needs to push a different sequence of buttons on his grandmother's microwave oven when he wants to use it for cooking.This is an example of:

Martha studied hard for her math test,and found that she learned some study habits that helped her study for her physics test.This is an example of:

If we train a discrete-component model to respond to a blue light,how will it respond to a blue-green light?

Describe how you could use discrimination training to teach a rat to distinguish between a red light and a green light.

In the peak shift effect,discrimination training results in a maximum response to:

_______ representations use a unique node to represent each individual stimulus.
