The relation between reinforcer magnitude and timing behavior was studied using a peak procedure. Four rats received multiple consecutive sessions with both low and high levels of brain stimulation reward (BSR). Rats paused longer and had later start times during sessions when their responses were reinforced with low-magnitude BSR. When estimated…

The representation of time and space are closely linked in the cognitive system. Optokinetic stimulation modulates spatial attention in healthy subjects and patients with spatial neglect. In order to evaluate whether optokinetic stimulation could influence time perception, a group of healthy subjects performed "time-comparison" tasks of sub- and…

The notion of general cognitive ability (or "intelligence") is explored and why the time might now be ripe for educators to re-consider the power offered by a general intellectual capacity which is itself amenable to educational influence. We review existing knowledge concerning general intelligence, including the cohabitation of general and…

Although advances in diffusion tensor imaging have enabled us to better study the anatomy of the inferior longitudinal fasciculus (ILF), its function remains poorly understood. Recently, it was suggested that the subcortical network subserving the language semantics could be constituted, in parallel with the inferior occipitofrontal fasciculus, by…

A program was recently developed to promote adaptive responses and upright head position in students with multiple disabilities through the use of microswitch clusters (i.e., combinations of two microswitches). The five students exposed to the program showed a significant increase in adaptive responses performed with head upright. The first…

The purpose of this study was to examine the relationships between transformational leadership in college classrooms (i.e., charisma, individualized consideration, intellectual stimulation), student learning outcomes (i.e., cognitive learning, affective learning, state motivation, communication satisfaction), student participation, and student…

Study Design: A systematic review of the literature. Objectives: To describe which environmental factors have an impact on community participation of persons with an intellectual disability. Methods: A systematic literature search was conducted for the period of 1996-2006 in Pubmed, CINAHL and PSYCINFO. Search terms were derived from the…

Article examined research that related stimulation to creativity. (Author/RK)

The purpose of this study was to determine whether antisocial preadolescent children display more stimulation seeking than normals or neurotics in a situation intentionally designed to be boring. (Author)

Alternative reinforcement strategies on a differential reinforcement of low rates of behavior schedule resulted in significant reduction of self-stimulatory behavior of 9- and 11-year-old autistic boys. Efforts were made to match the sensory consequences derived from the reinforcement to those presumed to be maintaining the self-stimulatory…

Performance of hyperactive and control elementary children (total N=70) on a noncolored search task was compared with a color stimulation version. It was concluded that performance on search-attentional tasks is normalized for hyperactive Ss, by added color, but that gains wear off more rapidly for hyperactive Ss. (CL)

Results of a study involving six autistic children (3-10 years old) indicated that self-stimulation occurred significantly more often with unfamiliar than with familiar therapists. There was a significant and negative correlation between the occurrence of self-stimulation and correct responding. (Author/CL)

Discusses research showing that material people learn when in a high arousal state and material they learn when in a normal arousal state is subsequently best recalled when they are in a similar arousal state. Speculates that this effect may partially underlie mood cuing, mood-related material from memory. (EKN)

The nature of eye-pressing as a visual stimulation mannerism in children with severely impaired eyesight is examined, and a possible physiological explanation (that self-stimulation occurs when the demand of the brain for meaningful visual information is not met) is offered. (CL)

Over 60 studies using behavioral strategies to suppress sterotypic responding in handicapped individuals were reviewed to identify populations studied, behavior observed, interventions employed, and relative effectiveness of interventions used alone or in combinations. Discussion center on relative effectiveness of interventions and their…
