1
New cards

Behaviour are context dependent. What does this mean?

Behaviour is valuable only at the right time and appropriate situation

2
New cards

Successful behaviour change depends on

teaching/learning when and where a behaviour is appropriate

3
New cards

Antecedent

Events or interactions that happen before the behaviour occurs

4
New cards

Behaviour

behaviour or sequence which has occurred

5
New cards

Consequence

events or interactions which happen after the behaviour

6
New cards

operant behaviour always influenced by

Environment, including people, places, objects, etc

7
New cards

Stimulus Control

degree of correlation between a stimulus and subsequent response

8
New cards

Good or Effective stimulus control

High correlation between presentation of stimulus and likelihood of the response occurring

9
New cards

SD – Discriminative Stimulus

Response has been reinforced only in the presence of a particular stimulus, Cue that a particular response will pay off

10
New cards

SΔ - Extinction Stimulus

Response has been extinguished only in the presence of a particular stimulus, Cue that a particular response will not pay off

11
New cards

A stimulus may be simultaneously an SD for one response and an SΔ for another. Example?

Teacher is a discriminative Stimulus for raising their hand, but also a extinction stimulus because kids do not act out, speak out, ect

12
New cards

Stimulus Discrimination

Process by which we learn to emit a specific behaviour in the presence of some stimuli and not in the presence of other stimuli

13
New cards

Operant Stimulus Discrimination Training:

Procedure of reinforcing a response in the presence of an SD and extinguishing that response in the presence of an S∆

New cards

Stimulus Generalization

Responding the same way to a different stimulus

31
New cards

Unlearned stimulus generalization due to considerable physical similarity

Likely to perform a behaviour in a new situation if that situation is very similar to situation when behaviour was learned (e.g., D2L, Blackboard, Moodle, Canvas)

32
New cards

Learned stimulus generalization involving minimal physical similarity

Have to learn the stimulus class, or concept

33
New cards

Common-element stimulus class

Set of stimuli, all of which have some physical characteristic in common

34
New cards

Conceptual behaviour

emitting appropriate behaviour to all members of a common-element stimulus class, but not those that don't belong to the class

35
New cards

Contingency

if-then arrangement (press button on water fountain then water will come)

36
New cards

Two-term contingency

Behaviour-consequence

37
New cards

Three-term contingency

As and Cs of a B (explains what cues in the environment influence the behaviour)

38
New cards

Contingency shaped behaviour

developed through trial and error

39
New cards

Rule-governed behaviour

controlled by statement of a rule

40
New cards

Fading

Gradual change over successive trials of an antecedent stimulus that controls a response so that the response eventually occurs to a partially changed or completely new stimulus

Process of slowly removing prompts after behaviour is established

41
New cards

Dimension

any characteristic of the stimulus that can be measured on some continuum (loud to soft, heavy pressure to no pressure)

42
New cards

Fading occurs along

dimensions of stimuli

43
New cards

Prompt

a supplemental antecedent stimulus provided to increase the likelihood that a desired behaviour will occur, but that is not the final target stimulus to control that behaviour (physical, gestural, modeling and verbal)

44
New cards

Extra-stimulus prompts

something that is added (adding a sticky note or a parent pointing to a fork when asking a child to pass them the fork)

45
New cards

Within-stimulus prompts

alterations to the SD or S∆ to make them more noticeable and easier to discriminate
