Autistic children's blood pressure, heart rate, peripheral blood flow (PBF), and peripheral vascular resistance (PVR) were measured during three types of tasks (reaction time, social interaction, at rest). Disturbances in filtering environmental stimulation and modulating response to novelty may be part of the basic pathology of autism apparent…

Research among rank and file members of the Osher Lifelong Learning Institute in Portland, Maine was conducted to investigate the perceived benefits of participation in a peer-governed and taught elder learning program. Interviews were conducted with 45 long-term members of the program by 6 focus groups. Benefits were reported in 4 categories:…

The study of subliminal perception in normal and brain lesioned subjects has long been of interest to scholars studying the neural mechanisms behind conscious vision. Using brief durations and a developed methodology of introspective reporting, we present an experiment with visual stimuli that gives rise to little or no subliminal perception under…

Recent studies using lesion, infusion, and unit-recording techniques suggest that the infralimbic (IL) subregion of medial prefrontal cortex (mPFC) is necessary for the inhibition of conditioned fear following extinction. Brief microstimulation of IL paired with conditioned tones, designed to mimic neuronal tone responses, reduces the expression…

This study compares the effect of an acceptance-based protocol (ACT) and a cognitive control-based (CONT) protocol on three measures of pain coping: tolerance, self-report, and believability. Specific methodological controls were employed to further isolate the role of the value of participating in a pain task, compared to previous investigations…

Undergraduate research programs are becoming more prevalent, but research on the processes and outcomes is limited and deals largely with perceptions of student learning gains. This paper adds to the literature by describing undergraduate research activities from the student perspective. A phenomenological approach was used to analyze journals…

This study investigated if a relationship existed between student achievement in 10th grade Missouri Assessment Program mathematics and 11th grade communication arts scores in 2007 and high school leadership team perceptions of the extent to which they demonstrated leadership practices. The secondary purpose was to compare perceptional…

Upon stimulation, areas of the brain associated with specific cognitive processing tasks may undergo observable physiological changes, and measures of such changes have been used to create brain maps for visualization of stimulated areas in task-related brain "activation" studies. These perturbations usually continue throughout the period of the…

Neurogranin (Ng), a PKC substrate, is abundantly expressed in brain regions important for cognitive functions. Deletion of Ng caused severe deficits in spatial learning and LTP in the hippocampal CA1 region of mice. These Ng-/- mice also exhibit deficits in the amplification of their hippocampal signaling pathways critical for learning and memory.…

Purpose: To compare the effects of conventional amplification (CA) and digital frequency compression (DFC) amplification on the speech recognition abilities of candidates for a partial-insertion cochlear implant, that is, candidates for combined electric and acoustic stimulation (EAS). Method: The participants were 6 patients whose audiometric…

Aims: The human immunodeficiency virus (HIV) potentially causes a significant encephalopathy and resultant developmental delay in infected children. The aim of this study was to determine whether a home-based intervention programme could have an impact on the neurodevelopmental status of children infected with HIV. Method: A longitudinal,…

The purposes of the present study were to examine associations between risk factors and the cognitive performance from one to three years of age of children living in poverty, and to investigate the protective and/or promotive effects of EHS on children's cognitive skill performance. Analyses were conducted using data from the Early Head Start…

Cultures differ with respect to parenting strategies already during infancy. Distal parenting, i.e., face-to-face context and object stimulation, is prevalent in urban educated middle-class families of Western cultures; proximal parenting, i.e., body contact and body stimulation, is prevalent in rural, low-educated farmer families. Parents from…

Single pulse transcranial magnetic stimulation (TMS) was applied to the hand area of the left primary motor cortex or, as a control, to the vertex (STIMULATION: TMS[subscript M1] vs. TMS[subscript vertex]) while right-handed volunteers silently read verbs related to hand actions. We examined three different tasks and time points for stimulation…
