Background: Response-contingent time-out has been shown to be an effective technique for enhancing fluency in people who stutter. However, the factors that determine individual responsiveness to time-out are not well understood. Aims: The study investigated the effectiveness of using response-contingent time-out to reduce stuttering frequency in…

The present study evaluated a new 30-day Web-based contingency management program for smoking abstinence with 4 daily-smoking adolescents. Participants made 3 daily video recordings of themselves giving breath carbon monoxide (CO) samples at home that were sent electronically to study personnel. Using a reversal design, participants could earn…

Four hundred thirty-two public sector therapists attended a workshop in contingency management (CM) and were interviewed monthly for the following 6 months to assess their adoption and initial implementation of CM to treat substance-abusing adolescent clients. Results showed that 58% (n = 131) of the practitioners with at least one…

Negative self-images are a maintaining factor in social phobia. A retrospective study (Hackmann, A., Clark, D.M., McManus, F. (2000). Recurrent images and early memories in social phobia. Behaviour Research and Therapy, 38, 601-610) suggested that the images may be linked to early memories of unpleasant social experiences. This preliminary study…

Schools in the UK looking for solutions to concerns about indiscipline have been enthused by the basic premise of restorative practice; the need to restore good relationships when there has been conflict or harm; and develop a school ethos, policies and procedures that reduce the possibilities of such conflict and harm arising. In 2004 the…

Recent demonstrations of "reconsolidation" suggest that memories can be modified when they are reactivated. Reconsolidation has been observed in human procedural memory and in implicit memory in infants. This study asks whether episodic memory undergoes reconsolidation. College students learned a list of objects on Day 1. On Day 2, they received a…

The authors argue that human sequential learning is often but not always characterized by a shift from stimulus- to plan-based action control. To diagnose this shift, they manipulated the frequency of 1st-order transitions in a repeated manual left-right sequence, assuming that performance is sensitive to frequency-induced biases under stimulus-…

Lists potential reinforcers that may be employed with various motivational tactics, and groups them into ten categories with specific examples of each. Most of these reinforcers may be used in manager-evaluated contingencies, with the exception of a few, which are listed because of their value in self-control tactics. (Author/VT)

The study evaluated methods for empirically identifying environmental determinants of aggressive and disruptive behavior in three developmentally delayed children. Sessions were designed to simulate contingencies maintaining aggression and disruption in the subjects' natural environments. Results showed variability between and within subjects. A…

Each instance of out-of-seat behavior of four hyperactive moderately/severely mentally retarded eight and nine year olds resulted in return to seat followed by 15-second physical restraint. Out-of-seat behavior of all four Ss increased during two implementations of the restraint contingency compared to levels during alternative baseline periods.…

Three punishment procedures--contingent applications of water mist, lemon juice, and vinegar--were evaluated as aversive treatment methods for a self-stimulatory behavior exhibited by a severely retarded 11-year-old male. The water mist procedure was as effective as lemon juice or vinegar, presented less physical threat to the client, and was…
