Forty-two parents of children with autistic disorder, 15 children with autistic disorder, 17 siblings of children with autistic disorder, and 12 unrelated normal controls were studied for binding characteristics of their immunoglobulins. Results did not support the hypothesis that two specific autoantibodies are characteristic of autism.…

Advances in the genetics and cell biology of muscle development are discussed. In-vitro analysis of the renaturation, polymerization, and three-dimensional structure of the purified proteins involved is described. (CW)

Appreciation of the effect of reduced access to meaningful sounds due to hearing loss can help gerontologists understand clients' response behaviors that seem off target or out of place. Gerontologists should have the ability to assess the need for changes in communication patterns in order to assist older adults with quality of life issues. (SK)

Investigated the role of physiological self-regulation (cardiac vagal tone) in information processing (habituation) in infants. Found that decreases in vagal tone consistently related to habituation efficiency at 2 and 5 months. Within- and between- age suppression of vagal tone predicted accumulated looking time (ALT), but ALT did not predict…

Presents the results of an annual survey of Physiology Departments (n=101) that elicited information about faculty salary, overall department budgets, and space allocations for research. Data is displayed using extensive charts and graphs. (DDR)

This study examined effects of manipulating lung volume on phonatory and articulatory kinematic behavior during sentence production in ten healthy adults. Significant differences at different lung volume levels were found for sound pressure level, fundamental frequency, semitone standard deviation, and upper and lower lip displacements and peak…

Introduces an educational game in pulmonary physiology developed for first-year medical students based loosely on the popular television game show, Who Wants to Be A Millionaire. Aims to provide students with an educational tool by which to review material previously presented in the class. (Author/YDS)

Materials and Resources: The Unfair Hearing Test audiocassette tape, audiocassette tape player, a sheet of paper with three columns numbered from 1-10, and writing utensils. Grade Level 3-12. May be adapted for college-level and preservice educators. Objectives: After participating in the Unfair Hearing Test exercise, students will be able to: 1.…

To determine the effect of asymmetrical signal degradation on binaural speech recognition, 28 children and 14 adults were administered a sentence recognition task amidst multitalker babble. There were 3 listening conditions: (a) monaural, with mild degradation in 1 ear; (b) binaural, with mild degradation in both ears (symmetric degradation); and…

The discipline of neuroscience draws from the fields of neurology, psychology, physiology and biology, but is best understood in the wider world as brain science. Of particular interest for education is the development of techniques for imaging the brain as it performs different cognitive functions. Cognitive neuroimaging has already led to…

This article presents an overview of the normal anatomy and physiology of the pediatric larynx, followed by some examples of pediatric voice disorders that were chosen to exemplify the alterations to the laryngeal anatomy and the subsequent modifications to laryngeal function. Vocal fold nodules are primarily reviewed due to their high incidence…

In speech research, it is often desirable to assess quantitatively the variability of a set of speech movement trajectories. This problem is studied here using synthetic trajectories, which consist of a common pattern and terms representing amplitude and phase variability. The results show that a technique for temporal alignment of the records…

The misconceptions regarding the nature of ATP hydrolysis and bond breaking are discussed. The students' knowledge in this area is quantitatively measured by a survey of over 600 biochemistry and physiology students.

This article addresses five commonly stated misperceptions concerning the effects of minimal hearing loss on the education of children. Helping educators and other professionals recognize these and other possible misperceptions is the first step in appropriately educating children with minimal hearing loss. Making educators and other professionals…

This paper discusses the current fashion for brain-based learning, in which value-laden claims about learning are grounded in neurophysiology. It argues that brain science cannot have the authority about learning that some seek to give it. It goes on to discuss whether the claim that brain science is relevant to learning involves a category…
