a reliable relation between behavior and an environmental variable

gradual unintended changes in how an intervention is implemented

a verbal operant evoked by a nonverbal stimulus and followed by generalized reinforcement

behavior mediated by a listener

reinforcing a behavior that cannot occur at the same time as problem behavior

adding an extra feature to make the correct stimulus stand out

time between a stimulus and the start of a response

a more salient stimulus interferes with learning about another

a single-case experimental design that verifies effects by reversing conditions

recording all instances of behavior

teaching a chain by starting with the first step

a verbal operant in which the form of the response has point-to-point correspondence but no formal similarity to a verbal stimulus

a single-case experimental design that demonstrates control by systematically changing performance criteria

the variable deliberately manipulated

shaping that changes a dimension of the same response form

repeated demonstration of the same effect

intermediate steps toward the final response

a schedule in which reinforcement is delivered for some, but not all, occurrences of behavior

teaching procedures designed to prevent learner errors

a verbal operant evoked by a verbal stimulus without point-to-point correspondence
