Discriminative Stimuli

Front 1

Concept Formation

Back 1

A complex example of stimulus control that requires stimulus generalization within a class of stimuli and discrimination between classes of stimuli.

Front 2

Antecedent Stimulus Class

Back 2

A set of stimuli that share a common relationship; all will evoke the same operant or respondent behavior (e.g., the color red).

Front 3

Feature Stimulus Class

Back 3

A set of stimuli that share common topographical structure or common spatial arrangements.

Front 4

Arbitrary Stimulus Class

Back 4

Set of stimuli that evoke the same response but do not share a common stimulus feature.

Front 5

Matching-to-Sample

Back 5

A procedure for investigating conditional relations and stimulus equivalence.

Front 6

Stimulus Equivalence

Back 6

The emergence of accurate responding to untrained and non-reinforced stimulus-stimulus relations following the reinforcement of responses to some stimulus-stimulus responses (reflexivity [A=A], symmetry [if A=B, then B=A], and transitivity [A=C, C=A from A=B and B=C]).

Factors Affecting Development of Stimulus Control

Back 7

1. Preattending Skills
2. Stimulus Salience
3. Masking and Overshadowing

Front 8

Masking

Back 8

Though one stimulus has acquired stimulus control over behavior, a competing stimulus can block evocative function of that stimulus.

Front 9

Overshadowing

Back 9

The presence of one stimulus condition interferes with the acquisition of stimulus control by another stimulus.

Front 10

Reducing the influence of masking and overshadowing

Back 10

1. Rearranging the physical environment.
2. Making instructional stimuli appropriately intense.
3. Consistently reinforcing behavior in the presence of the instructionally relevant stimuli.

Front 11

Three Major Forms of Response Prompts

Back 11

1. Verbal Instructions
2. Modeling
3. Physical Guidance

Front 12

Stimulus Prompts

Back 12

1. Movement Cue
2. Position Cue
3. Redundancy Cue

Front 13

Transferring Stimulus Control from Response Prompts to Naturally Existing Stimuli

Back 13

1. Most-to-Least Prompts
2. Graduated Guidance
3. Least-to-Most Prompts
4. Time Delay (constant and progressive)

Front 14

Transfer of Stimulus Control Using Control Shaping

Back 14

1. Stimulus Fading
2. Stimulus Shape Transformations

Front 15

Stimulus Fading

Back 15

Highlighting a physical dimension (e.g., color, size, position) of a stimulus to increase the likelihood of a correct response.

Front 16

Stimulus Shape Transformation (Stimulus Shaping)

Back 16

Uses an initial stimulus shape that will prompt a correct response. The shape is then gradually changed to form the natural stimulus, while maintaining the correct responding.
