One mildly and two borderline mentally retarded children (10 to 12 years old) were treated for spelling deficits using either overcorrection or overcorrection plus reinforcement. Overcorrection with reinforcement proved to be more effective than overcorrection alone for two of the three children. (Author)

Both the directions and the directions plus reinforcement groups increased subjects' time on the task during the experimental phases. When extrinsic reinforcement and directions were removed, they maintained intrinsically motivated behaviors at levels significantly above levels observed during the baseline phase and significantly higher than the…

It is through the selection of responses that are to serve as the organism's guests that many of the organism's characteristics and outcomes are determined. (MS)

This study assessed the adequacy of Gewirtz's interpretation of vicarious reinforcement and examined the development of responsiveness to vicarious reinforcement in an experiment in which 98 children (21/2-5 years) performed a discrimination problem while being exposed to a model who was either rewarded or punished on each trial.

Describes installation of a hybrid chilled water/ice thermal storage plant for the Lucile Erwin Middle School in Loveland, Colorado, which has saved more than $18,000 in energy costs annually. (EV)

Describes how the Brevard County School District in Florida teamed with companies EPRI and Florida Power and Light to implement a dual-path, low temperature air-distribution system used in conjunction with thermal energy storage. (EV)

Five male preschool children were studied to determine the extent to which the generalized motor imitation model applies to vocal imitation. The use of a reinforced-imitation condition produced a systematic increase in verbal matching responses among three of the five children, which is consistent with previous studies. (SW)

Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments were designed to determine whether consummatory behavior is similarly affected by downshifts of equal proportions. Within…

The authors comment on B. Gawronski and G. V. Bodenhausen's (2006; see record 2006-10465-003) associative-propositional evaluation model of implicit and explicit attitudes by examining the claims that (a) truth value is attached to propositions but not to associations; (b) pattern activation is qualitatively different from syllogistic structure of…

In Experiment 1, 12 senior citizens from the community were trained with 18 sets of conditional discriminations. Training included 2-, 3-, and 4-choice matching-to-sample (MTS) configurations in linear series (LS), many-to-one (MTO), and one-to-many (OTM) training structures. Training structure order was counterbalanced across participants. The…
