Flashcards in chapter 17 Deck (18):
1

stimulus control

Behaviors occur more often in the presence of an SD than its absence
-occurs when the rate, latency, duration or amplitude of a response is altered in the presence of an antecedent stimulus

2

stimulus generalization

stimuli that share similar physical properties evoke a response like the orginial stimulus

3

stimulus generalization gradient

graphically depicts the degree of stimulus generalization and discrimination by showing the extent to which responses reinforced in one stimulus condition are emitted in the presence of untrained stimuli

4

stimulus discrimination training

requires one bx and two antecedent stimulus conditions. responses are reinforced in the presence of one stimulus condition, SD, and not the other S-delta

5

concept formation

complex example of stimulus control that requires both stimulus generalization with a class of stimulus discrimination between classes of stimulus

6

antecedent stimulus class

set of stimuli that share a common relationship. all will evoke the same operant response class or elicit the same respondent BX

7

arbitrary stimulus class

stimuli that evoke the same response but do not share a common stimulus feature
(they do not share physical form or relational relationships

8

feature stimulus class

stimulus class that share common physical or common relative relations

9

stimulus eviquivance

emergence of accurate responding to untrained and non reinforced stimulus-stimulus relations. following reinforcement of responses to some stimulus-stimulus relations.

10

reflexilty

occurs when the absence of training and reinforcement a response will select a stimulus that is matched to itself
A=A

11

symmetry

occurs with reversibility of the sample stimulus and comparison stimulus
if A=b then B=A

12

Transitivity

an untrained stimulus-stimulus relation that emerges as a product of training 2 other stimulus-stimulus relations
A=B and B=C, so A=C

13

response prompts

operate directly on the response
-verbal instructions
-modeling
-physical guidance

14

Stimulus prompts

operate directly on the antecedent task stimuli to cue a correct response in conjunction with an SD
use movement, position and redundancy

15

Transfer of stimulus control
from response prompts to naturally occurring stimuli

-most to least prompts
-gradual guidance
-least to most prompts
-time delay

16

Transfer of stimulus control using stimulus control shaping

-stimulus fading
-stimulus shape transformations

17

stimulus delta

a stimulus in the presence of which a given behavior has not produced reinforcement in past

18

matching to sample

a procedure for investigating conditional relations and stimulus equivalence. Trail begins with the participant making a response that presents or reveals the sample stimulus, next the sample stimulus may or may not be removed and 2 or more comparison stimuli are presented. participant selects comparison stimuli. Responses that comparison match sample are reinforced.
