Psy 421 Ch 10.2 Flashcards
A discrimination training procedure in which the S+ and S- are presented one after the other in random sequence
Successive discrimination training
A discriminationtraining procedure in which the the S+ and S- are presented at the same time
Simultaneous dicrimination training
A discrimination training procedure in which the task is to select from two or more comparison stimuli the one that matches a sample
MTS discrimination training
A form of discrimination training in which the S- is introduced in very weak form and gradually strengthened. The usual result is that discrimination is achieved with few or no erros
Errorless Discrimination training
The finding that discrimination training proceeds more rapidly when different behaviors produce different reinforcers
Differential outcomes effect
The tendency for a behavior to occur in the presence of an S+ but not in the presence of an S-
Stimulus control
This theory is physiological. Believed that discrimination training produces physiological changes in the brain
Pavlov’s Theor of Generalization and discrimination
This theory proposed that the tendency to respond to any given stimulus was the result of the interaction of the increased and decreased tendencies to respond, as reflected in gradients of escitation and inhibition.
Spence’s Theory of Generalization and Discrimination
A generalization gradient showing an increased tendency to respond to the S+ or CS+ and stimuli resmebling them
Excitatory gradient
A gradient showing a decreased tendency to respond to the S- or CS- and stimuli resembling them
Inhibitory gradient
The tendency folllowing discrimination training for the peak of responding in a generalization gradient to shift away from the CS- or S-
Peak Shift
Refers to any class the members of which share one of more defining features
concept
What procedure did Pavlov employ to produce experimental neurosis
Discrimination training
