When a predictable change in behavior (D.V.) can be reliably produced by the systematic manipulation of some aspect of the persons environment (IV)

Experiments that show convincing changes in behaviour as result of the I.V. and not the result of uncontrolled/ unknown variables

Confounding Variables

Uncontrolled variables known as or suspected to exert an influence on the D.V.

Commonly refers to the degree to which a study's results are generalized to other subjects/ settings/ behaviors

Experimental question

A brief but specific statement of what the researcher wants to learn from conducting the experiment

Single Subject Research Design

Experiments in ABA; Experimental logic or reasoning for analyzing behaviour changes often employs the subject as her own control

Any aspect of the experimental setting (lighting/ temperature) that must be held constant to prevent unplanned environmental variation

Particular arrangement of conditions in a study so that meaningful comparisons of the effects of the presence, absence, or different values of the I.V. can be made

Steady/ Stable State of Responding

A pattern of responding that exhibits relatively little variation in its measured dimensional quantities over a period of time

Prediction, Verification, Replication

A condition of an experiment in which the I.V. is not present; basis for determining the effects of the I.V.

A data path that shows an increasing trend in the response measure over time

A data path that shows a decreasing trend in the response measure over time

The anticipated outcome of a presently unknown or future measurement

Accomplished by demonstrating that the prior level of baseline responding would have remained unchanged had the I.V. not been introduced

Repeating I.V. manipulations conducted previously in the study and obtaining similar outcomes

Analyzing Behaviour Change: Basic Assumptions + Strategies

Question	Answer
Experimental Control	When a predictable change in behavior (D.V.) can be reliably produced by the systematic manipulation of some aspect of the persons environment (IV)
Internal Validity	Experiments that show convincing changes in behaviour as result of the I.V. and not the result of uncontrolled/ unknown variables
Confounding Variables	Uncontrolled variables known as or suspected to exert an influence on the D.V.
External Validity	Commonly refers to the degree to which a study's results are generalized to other subjects/ settings/ behaviors
Experimental question	A brief but specific statement of what the researcher wants to learn from conducting the experiment
Single Subject Research Design	Experiments in ABA; Experimental logic or reasoning for analyzing behaviour changes often employs the subject as her own control
Extraneous Variables	Any aspect of the experimental setting (lighting/ temperature) that must be held constant to prevent unplanned environmental variation
Experimental Design	Particular arrangement of conditions in a study so that meaningful comparisons of the effects of the presence, absence, or different values of the I.V. can be made
Steady/ Stable State of Responding	A pattern of responding that exhibits relatively little variation in its measured dimensional quantities over a period of time
Baseline Logic	Prediction, Verification, Replication
Baseline	A condition of an experiment in which the I.V. is not present; basis for determining the effects of the I.V.
Ascending Baseline	A data path that shows an increasing trend in the response measure over time
Descending Baseline	A data path that shows a decreasing trend in the response measure over time
Prediction	The anticipated outcome of a presently unknown or future measurement
Verification	Accomplished by demonstrating that the prior level of baseline responding would have remained unchanged had the I.V. not been introduced
Replication	Repeating I.V. manipulations conducted previously in the study and obtaining similar outcomes
