History effects on induced and operant variability

Abstract

Two experiments evaluated history effects on induced and operant variability. College students typed
three-digit sequences on a computer keyboard. Sequence variability was induced (by no reinforcement or
variation- independent reinforcement) or reinforced (by variation- or repetition-dependent reinforcement).
Conditions with induced and operant variability were presented according to a reverse between-groups de-
sign. In Experiment 1, we examined transitions from the variation or repetition contingencies to no reinforce-
ment, and vice versa. In Experiment 2, the variation or repetition contingencies were followed or preceded
by variation-independent reinforcement. The results showed that (1) a history of no reinforcement impaired
operant variability learning; (2) induced variability levels were higher and lower after a history of reinforce-
ment for variation and repetition, respectively; (3) repetition was more easily disrupted by no reinforcement
and independent reinforcement than was variation; and (4) response variability and stability were a function
of past and current reinforcement conditions. These results indicate that reinforcement history influences both
induced and operant variability levels

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
