Extinction of classically conditioned fear, like its acquisition, is active learning, but little is known about its molecular mechanisms. We recently reported that temporal massing of conditional stimulus (CS) presentations improves extinction memory acquisition, and suggested that temporal spacing was less effective because individual CS…

In speech perception, children give particular patterns of weight to different acoustic cues (their cue weighting). These patterns appear to change with increased linguistic experience. Previous speech perception research has found a positive correlation between more analytical cue weighting strategies and the ability to consciously think about…

Problem behavior is a primary barrier to successful community inclusion for people with developmental disabilities and therefore a major priority for intervention efforts. Recently, researchers and clinicians have begun to focus on the systematic assessment of a broad range of contextual variables that purportedly affect problem behavior. In the…

In this article, we describe a pilot study that investigated the effectiveness of group cognitive behavioral therapy (CBT) for auditory hallucinations. Eleven inpatients with either chronic schizophrenia or schizoaffective disorder participated in 2 CBT groups of differing treatment duration (i.e., 7 versus 20 sessions). The results showed that…

We investigated the nature of graphic formulas in 5-, 7-, and 9-year-old children when they were asked to draw a house and a television in a free condition, and then to draw from photographs of these objects. Assuming that the frequency of occurrence of a feature in children's drawings reflects its semantic weight, we studied the relations between…

Fifteen children diagnosed with specific language impairment (SLI) and 15 typically developing (TD) children were tested for identification performance on 2 synthetic speech continual varying in formant transition durations (FTDs). One continuum varied from /ba/ to /wa/, and the other varied from /da/ to /ja/. Various d'-related measures from…

Previous research has suggested that children with specific language impairments (SLI) have deficits in basic speech perception abilities, and this may be an underlying source of their linguistic deficits. These findings have come from studies in which perception of synthetic versions of meaningless syllables was typically examined in tasks with…

The present study investigated the transfer of induced happy and sad mood functions through equivalence relations. Sixteen subjects participated in a combined equivalence and mood induction procedure. In Phase 1, all subjects were trained in 2 conditional discriminations using a matching-to-sample format (i.e., A1-B1, A2-B2, A1-C1, A2-C2). In…

This qualitative study provides student perceptions of interactive whiteboard (IWB) use in a secondary biology classroom. The use of the IWB was alternated with the overhead on an ABAB and BABA design in two classrooms. The study was based on semi-structured interviews of thirty-six individuals, representing a sample of rural, high school…

Systemic functional linguistics (SFL) was the foundation for this study that explored the effect of science text and image integration on grade 9 students' reading comprehension. Two texts in Chinese on the moon phase with different print and image integration were compared--a traditional textbook (TT) used in Taiwanese junior high schools and a…

Findings from two studies of 42 children with profound developmental delays (26 males and 15 females) using systematic and intense response-contingent learning opportunities interventions are reported. Response-contingent learning games were used to promote the participants' use of behavior that either produced environmental consequences or…

Functional analyses of problem behavior for 4 young boys with developmental delays showed that problem behaviors were maintained by both negative and positive reinforcement. Functional communication training was conducted with one set of training stimuli in which the child's mother presented a work task in the family living room. Pretreatment…

The purpose of this study was to investigate the critical attributes of mathematical software designed for children between the ages of four and seven. This study sought to offer guidelines that will assist software designers in the design of developmentally appropriate educational software. In addition, teachers and parents may benefit from this…

This article describes a participatory action research (PAR) project conducted in a large urban, co-educational secondary school. The project focused on two senior pupils with autism spectrum disorder (ASD) who, seemingly as a result of feeling stressed or anxious, displayed behaviours that inhibited communication. Using questionnaires,…

The effects of three classes of reinforcing stimuli were compared across three students with profound intellectual disabilities. A multielement design with no baseline and final "best treatments" phase was used to measure the frequency of single-switch activations by each student across treatments. The three interventions were Treatment A, adapted…
