We investigated whether postextinction administration of methylene blue (MB) could enhance retention of an extinguished conditioned response. MB is a redox compound that at low doses elevates cytochrome oxidase activity, thereby improving brain energy production. Saline or MB (4 mg/kg intraperitoneally) were administered to rats for 5 d following…

Three experiments show latent (or incidental) learning of salt-cue relationships using a conditioned cue-preference paradigm. Rats drank a salt solution while confined in one compartment and water in an adjacent, distinct compartment on alternate days. When given access to the two compartments with no solutions present, sodium-deprived rats…

The objective of this study was to compare enhanced access to geriatric assessment and case management to usual home care service provision for the frail elderly. This was a demonstration project, with randomized allocation to control or intervention groups of frail elderly persons who had been referred to the Home Care service in Winnipeg. Of the…

The objectives of the study are to assess the impact of a community-based bicycle-helmet program aimed at children aged 5-12 years (about 140,000). A quasi-experimental design, including a control group, was used. Sex- and age-group-based changes in the risk of bicycle-related head injury leading to hospitalisation were measured, using rate…

This study evaluated an intervention for building undergraduates' technological literacies for higher education in support of use of the learning management system and desktop applications. Self-efficacy scores between a control group and a treatment group were compared. Relationships between scores and demographic/experiential variables were also…

The purpose of this study was to investigate the effects of retroactive and focused self-monitoring, actualized by videotaping, on children's theater performance. In Experiment 1, 20 students in a theater performance program were randomly assigned to either a control or a self-monitoring condition, and their weekly rehearsals were videotaped. Only…

Aim: To evaluate the effectiveness of a multiservice intervention designed to move substance-abusing women on welfare to sobriety and self-sufficiency by addressing their substance abuse, domestic violence, employment, and basic needs. Design: A field evaluation with repeated measures at 6 and 12 months on an intent-to-treat sample of 529 women…

This study examines the use of a cooperative physical games program "The Game Factory" on social behaviour among children. Children are required to work together towards positive collective outcomes. A pretest-intervention-posttest design is used. Parents and teachers assessed 90 Australian primary school children in two experimental…

Purpose: To study the performance of final year medical students, at the end of module assessments, following exposure to a web-based tutorial programme designed to facilitate critical thinking and logical reasoning. Method: Multimedia enhanced web-based tutorials based on patient oriented problems, designed to develop higher cognitive skills in…

Objective: To describe the effects of a controlled family-based health education/counseling intervention on health behaviors of children with a familial history of cardiovascular diseases (FH-CVDs). Methods: The intervention group (IG, n=432) received 5 counseling sessions. The control groups 1 (CG1, n=200) and 2 (CG2, n=423) received no…

Teacher education students who participated in a Multicultural Relationship Enhancement program showed significant improvement in empathic listening and expressive speaking in conflictual multicultural situations. No significant difference was found between participants and a wait-list control group on a measure of prejudice. (Contains 1 figure…

Although reattribution training has been shown to be very useful in improving learning, researchers disagree on what mediates the effects. As to the possible mediating factors, the prominent theories suggest factors such as expectations, notions of intelligence, self-efficacy or anxiety. However, this article proposes an alternative mediating…

The purpose of this study was to investigate the effects of multiple intelligences (MI) teaching approach on 8th Grade students' achievement in and attitudes toward science. This study used a pretest-posttest control group experimental design. While the experimental group (n=30) was taught a unit on acids and bases using MI teaching approach, the…

Language delay and impairment are salient features of autism. More specifically, there is evidence of atypical semantic organization in autism, but the functional brain correlates are not well understood. The current study used functional MRI to examine activation associated with semantic category decision. Ten high-functioning men with autism…

This paper presents the methodology and main results of a longitudinal study in Greece that explored the learning and psychosocial difficulties of immigrant pupils, as compared with those of their Greek classmates. The "Teacher-Child Rating Scale" (T-CRS) and "Child Rating Scale" (CRS) were used as instruments to measure the…
