Classroom behavior and children with mental retardation: Comparison of children with and without ADHD

Thirty-four children (ages 6–12 years) with moderate to borderline mental retardation were studied in a laboratory classroom setting to determine whether children identified as having attention deficit hyperactivity disorder on the basis of Conners Questionnaires differed in classroom behavior. Half of the children scored 15 or greater on both the Parent and Teacher Conners; the remaining children scored 11 or less. All were participants in a Saturday Education Program serving children with mental retardation. Direct observation of the laboratory classroom documented significant differences between groups on measures of on-task behavior and fidgetiness, especially during situations where little direct teacher feedback or supervision was available. Saturday Education Program staff, while blind as to group designation, rated the two groups as differing significantly on all scales of two standardized behavior problem checklists. Checklists by parents and teachers appear to be valid measures of classroom behavior of children with moderate to borderline mental retardation.This research was supported by a grant to the first author from the National Institutes of Child Health and Human Development, U.S. Department of Health and Human Services, grant No. 1R29HD26186-01A1.

The role of the hospital in the evolution of elite cultures of medicine

Rosenberg argues that a culture of medicine articulates a unique medical vision reflecting scientific ideologies and perceptions, professional values and rewards, career patterns, and the work context of each generation of physicians (Rosenberg, 1987, p. 7) It might be more accurate, however, to recognize multiple cultures of medicine. This papers traces American hospitals' contributions to three specific aspects of certain elite cultures of medicine. Its first section introduces and explores these aspects transhistorically. They are: a stratified paradigm of the physician-patient relationship, the equation of competence with specialization, and a pattern within a stratified model of medicine called the “Lone Ranger syndrome.” A brief historical profile subsequently highlights changes in the structure and function of American hospitals in the 19th century. The three remaining sections chart the ebb and flow of the prominence and power of these specific aspects of elite cultures of medicine across three historical periods: the late 19th century, 1910–1930, and the post World War II era.     

Development of an institutional policy on artificial hydration and nutrition

The issues involved in deciding whether to use artificial methods of delivering hydration and nutrition are often very difficult for patients, families, and health care providers. Once private and personal matters, these decisions now frequently involve the judicial system. Five years ago, Hospice of Washington recognized the need for a written policy and wrote the one published here. Its goal is to respect individual preferences and family concerns while addressing the nutrition and hydration needs of dying patients. The policy sets parameters on the issue, provides basic information, and encourages crafting the most fitting resolution to each situation.     

TEILHARD'S TWO ENERGIES

Abstract. Resolution of the entropy‐evolution problem was a significant issue for Pierre Teilhard de Chardin throughout his scientific career. Although never truly satisfied with his solution, he proposed that all energy must be psychic and contain two components. Tangential energy is related to physical energy. Radial energy in some way accounts for increasing complexity and consciousness in evolution. Analysis of developments in thermodynamics, statistical mechanics, and information theory show that Gibbs free energy contains both calorimetric and noetic components, thus validating Teilhard's intuition.     

Gender-moderated dorsolateral prefrontal reductions in 22q11.2 Deletion Syndrome: implications for risk for schizophrenia.

To investigate the impact of the microdeletion on morphology of the prefrontal cortex in 22q11.2 Deletion Syndrome (22q11.2 DS), high-resolution, anatomic magnetic resonance imaging was performed on 19 children and adolescents with 22q11.2 DS (11 females, 8 males) and 18 unaffected controls (10 females, 8 males). Tissue volumes of the dorsolateral, dorsomedial, orbitolateral, and orbitomedial prefrontal cortex were measured. Tasks of executive function and working memory were administered to investigate the association between anatomy and function. Whole brain volume and frontal lobe tissue volume were preserved in girls but reduced in boys with 22q11.2 DS relative to age-matched controls. Dorsolateral prefrontal cortex (DLPFC) volumes were reduced in participants with 22q11.2 DS, although the gender-by-diagnosis effect found for frontal lobe was not as robust for DLPFC. DLPFC volumes were associated with performance on tasks of planning and emotional facial recognition. Longitudinal studies are needed to clarify whether gender differences in frontal lobe and DLPFC persist with development, and whether the volumes of the DLPFC are associated with eventual deterioration in adaptive/psychosocial function that may presage the onset of schizophrenia, for which individuals with 22q11.2 DS are at a disproportionately high risk.     

Stereotype content of people with acquired brain injury: Warm but incompetent

Since stereotypes about people with acquired brain injury (ABI) can lead to prejudice, studying these stereotypes is highly important. In two studies, we examined these stereotypes both on idiosyncratic dimensions and on the two dimensions of the Stereotype Content Model. Participants completed a specific questionnaire about ABI and warmth and competence questionnaires regarding people with ABI and other social groups. Specific stereotypes about ABI were found to be underpinned by dimensions of “cognitive impairments and ADL limitations,” “catastrophic outcomes,” and “personal and interpersonal development.” Within the model, people with ABI were seen as being warm but incompetent. The ambivalent ABI stereotype could elicit prejudicial attitudes that may impede rehabilitation.
