Term
|
Definition
| a design to identify the active elements of a treatment conditions, the relative contributions of different variables in a treatment package, and/or the necessary and sufficient components of an intervention, compare levels of responding across successive phases in which the intervention is implemented with 1+ components left out |
|
|
Term
|
Definition
| an experiment in which the researcher attempts to duplicate exactly the conditions of an earlier experiment |
|
|
Term
|
Definition
| prevents the subject and the observer(s) from detecting the presence or absences of the treatment variable, used to eliminate confounding of results by expectations, differential treatment by others, and observer bias |
|
|
Term
|
Definition
| The extent to which procedures in all phases and conditions of an experiment, including baseline, are implemented correctly. |
|
|
Term
|
Definition
| (a) repeating conditions within an experiment to determine the reliability of effects and increase internal validity, (b) repeating whole experiments to determine the generality of findings of previous experiments to other subjects, settings, and/or behaviors |
|
|
Term
|
Definition
| An experiment in which the researcher purposefully varies one or more aspects of an earlier experiment |
|
|
Term
|
Definition
| An undesirable situation in which the independent variable of an experiment is applied differently during later stages than it was at the outset of the study. |
|
|
Term
|
Definition
| The extent to which the independent variable is applied exactly as planned and described and no other unplanned variables are administered inadvertently along with the planned treatment. |
|
|
Term
|
Definition
| An error that occurs when a researcher concludes that the independent variable had an effect on the dependent variable, when no such relation exists; a false positive. |
|
|
Term
|
Definition
| An error that occurs when a researcher concludes that the independent variable had no effect on the dependent variable, when in truth it did; a false negative. |
|
|
Term
|
Definition
| A procedure that prevents a subject from detecting the presence or absence of the treatment variable. To the subject, the placebo condition appears the same as the treatment condition (e.g., a placebo pill contains an inert substance but looks, feels, and tastes exactly lie a pill that contains the treatment drug). (See double blind control.) |
|
|
Term
|
Definition
The extent to which the experimenter controls all relevant variables in a given experiment.
a researchers ability to reliably produce a specified behavior change by manipulating an independent variable.
The primary means of assessing the degree of ______ _______ is through the attainment of steady state responding. |
|
|
Term
|
Definition
uncontrolled factors known or suspected to have exerted influence on the dependent variable.
Confounding variables that are uncontrolled are likely causes of variability in a study Repeated measurement both controls for and detects this variability. |
|
|
Term
|
Definition
changes that take place in a subject over the course of the experiment.
Control for maturation by using alternating treatment designs or multiple introduction and withdrawals of the independent variable
A potential confounding variable. |
