Applied Behavior Analysis Analyzing Behavior Change
This set explains analyzing behavior change in ABA, focusing on stable state responding—consistent behavior over time—and the steady state strategy, which controls extraneous variables to observe reliable behavioral patterns before introducing new conditions.
Stable state responding
a pattern of responding that exhibits relatively little variation in its measured dimensional quantities over a period of time.
Key Terms
Stable state responding
a pattern of responding that exhibits relatively little variation in its measured dimensional quantities over a period of time.
steady state strategy

Baseline
control condition and does not necessarily mean the absence of instruction or treatment.
stable baseline
data show no evidence of an upward or downward trend and all of the measures fall within a small range of values.
variable baseline
data points do not consistently fall within a narrow range of values
prediction
the anticipated outcome of a unknown or future measurement.

Stable state responding | a pattern of responding that exhibits relatively little variation in its measured dimensional quantities over a period of time. |
steady state strategy | repeatedly exposing a subject to a given condition while trying to eliminate or control any extraneous variables on the BX, and obtaining a stable pattern of responding before introducing the next condition. |
Baseline | control condition and does not necessarily mean the absence of instruction or treatment. |
stable baseline | data show no evidence of an upward or downward trend and all of the measures fall within a small range of values. |
variable baseline | data points do not consistently fall within a narrow range of values |
prediction | the anticipated outcome of a unknown or future measurement. |
affirmation of the consequent | the predictive power of a steady state responding enables the BX analyst to employ a kind of inductive logic |
practice effects | improvements in performance resulting from repeated opportunities to emit the BX. |
verification | accomplished by demonstrating that prior level of baseline responding would have remained unchanged had the IV not been introduced |
replication | repeating independent variable manipulations conducted previously in the study and obtaining similar outcomes. |
external validity | the degree in which a study’s findings have generality to other subjects, settings and/or behavior. |
A-B design | a 2 phase experimental design consisting a pre-treatment baseline condition (A) followed by a treatment condition (B) |
experimental control | achieved when a predictable change in BX can be reliably produced by the systematic manipulation of some person’s environment |
internal validity | experiments that show convincingly that changes in BX area function of the independent variable and are not the result of uncontrolled or unknown variables. |
confounding variables | uncontrolled variables known or suspected to exert and influence on the dependent variable |
experimental question | a brief but specific statement of what the researcher thats to learn from conducting the experiment |
single subject design | experimental logical or reasoning for analyzing BX changes often employs the subject as her own control |
extraneous variables | aspect of the environment that the experimenter must control |
experimental design | particular arrangement of conditions in a study so that meaningful comparisons of the effects of the presence, absence of different values of the IV can be made |
parametric analysis | seeks to discover the differential effects of range of values of the independent variable |
baseline logice | entails three elements- prediction, verification, replication |
