A-B design - Answer A research design consisting of a baseline and a treatment phase.
Affirmation of the consequent - Answer The three-step form of reasoning that begins with a
true antecedent-consequent statement and proceeds as follows: (1) if A is true, then B is true;
(2) B is found to be true; (3) therefore, A is true.
Ascending baseline - Answer A data path that shows an increasing trend in the response
measure over time.
Baseline - Answer The condition or phase in which no treatment is implemented.
Baseline Logic - Answer A term sometimes used to refer to the experimental reasoning
inherent in single-subject experimental designs that entails three elements: prediction,
verification, and replication.
Confounding variable - Answer An uncontrolled factor known or suspected to exert influence
on the dependent variable.
Descending baseline - Answer A data path that shows a decreasing trend in the response
measure over time.
Experimental control - Answer The outcome of an experiment that demonstrates convincingly
a functional relation, or the extent to which a researcher maintains precise control of the
independent variable by presenting it, withdrawing it, and/or varying its value.
Experimental question - Answer A statement of what the researcher seeks to learn by
conducting the experiment.
External validity - Answer The degree to which a study's findings are generalizable to other
subjects, settings, or behavior.
Extraneous variable - Answer Any aspect of the experimental setting, such as lighting or
temperature, which must be held constant to prevent unplanned environmental variation.
