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

adding an extra feature to make the correct stimulus stand out

intermediate steps toward the final response

time between a stimulus and the start of a response

the variable deliberately manipulated

gradual unintended changes in how an intervention is implemented

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

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

teaching procedures designed to prevent learner errors

repeated demonstration of the same effect

shaping that changes a dimension of the same response form

teaching a chain by starting with the first step

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

a more salient stimulus interferes with learning about another

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 verifies effects by reversing conditions

behavior mediated by a listener

a reliable relation between behavior and an environmental variable

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

recording all instances of behavior
