Effects of right and left hemisphere damage on performance of the "Right Hemisphere Communication Battery"

A Hebrew adaptation of Gardner and Brownell's (1986) "Right Hemisphere Communication Battery" (HRHCB) was administered to 27 right brain-damaged (RBD) patients, 31 left brain-damaged (LBD) patients, and 21 age-matched normal controls. Both patient groups showed deficits relative to controls and overall there was no difference between the two patient groups. A factor analysis of patients' scores on the HRHCB yielded two interpretable factors, a verbal and a nonverbal one. These factors were not lateralized. Performance of patients on the HRHCB correlated significantly and positively with performance on most tests of basic language functions, measured with a Hebrew adaptation of the "Western Aphasia Battery" (HWAB) and with other cognitive functions measured with standardized neuropsychological tests. There were stronger correlations of HRHCB with subtests of the HWAB in LBD patients and with nonlanguage cognitive tests in RBD patients. In the LBD group, HRHCB subtests' scores correlated negatively with lesion extent in frontal and temporal perisylvian regions. Such localization was not observed in RBD patients. The results argue against selective right hemisphere (RH) involvement in the RHCB, alleged to measure pragmatic aspects of language use, and show, instead, bilateral involvement. The results also argue against a modular organization of these functions of language use, especially in the RH.     

Neuronal changes in normal human aging and Alzheimer's disease

This article discusses age-related changes in brain weight, total number of cortical neurons, cortical dendrites, spine, and synapse density. The conclusion is that the present outlook is less grim than it was 30 years ago. Age-related reduction appears to be specific to brain region and cortical layer rather than a general feature. In addition, we describe a different pattern of changes that occur in Alzheimer's disease patients. This review concludes that the association cortices in particular are affected in aging and Alzheimer's disease and that the primary visual and somatosensory cortices are relatively spared.     

Groups to Resolve Conflicts Between Groups: Diplomacy with a Therapeutic Dimension

The group self, an individual's self-perception as a member of a group, is distinguished from the group's self, a personification of the group as a person with a self. The perceived group's self of an opposing other group is often a repository for attributes group members are not ready to recognize in their own group's self. Theoretically, the need for an adversarial other to hold one's own group's unwanted attributes—and thus to complete one's own group's self—contributes, however unconsciously, to the apparent intractability of intergroup disputes. In dealing with these issues, I compare intergroup conflict resolution (ICR) groups with therapy groups, on the one hand, and advocacy groups on the other. All of this sets the stage for a presentation of two ICR projects and their analysis in group-developmental terms.     

From agape to organs: religious difference between Japan and America in judging the ethics of transplant

This essay argues that Japan's resistance to the practice of transplanting organs from persons deemed "brain dead" may not be the result, as some claim, of that society's religions being not yet sufficiently expressive of love and altruism. The violence to the body necessary for the excision of transplantable organs seems to have been made acceptable to American Christians at a unique historical "window of opportunity" for acceptance of that new form of medical technology. Traditional reserve about corpse mutilation had weakened and, especially as presented by the theologian Joseph Fletcher, organ donation was touted as both expressive of agape and a way of "updating" Christianity via the ethics of Utilitarianism. Many Japanese, largely Buddhist and Confucian in their orientation, view these changed valorizations as neither necessary nor patently more ethical than those of their own traditions.     

The Late Life Reconstruction of Selfhood Analyzed in Peter Hall's Film She's Been Away

The film She's Been Away tells the story of an old woman who had been locked in a mental asylum while a teenager, for willfully violating repressive sexual codes. Sixty years later her ward is closed and she moves in with her nephew and his wife. Faced with what appears to be a hopeless situation, she manages to forge a sense of a meaningful closure to a misspent life. Through narrative, story structure, and characterization the film throws into focus coping mechanisms and ego strategies deployed by a triple disadvantaged person (woman, old, and mad) in her ascent to a reconstructed selfhood. As the protagonist ties both ends of her life, and faces the abyss in between she makes genuine adaptive use of so-called regressive, late-life development assets (available to a lesser degree to elderly people in normal life circumstances), primarily the abolition of linear time. Through this abolition she makes reminiscing an actual reality while still maintaining a functional separation between the real and the remembered. Her portrayal is a valuable document for gerontologists as it explores, through artistic imagination and intuition, the workings of an aging mind in search for a meaningful sense of closure.     

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.     

Traumatic Brain Injury as a Risk Factor for Alzheimer's Disease: A Review

Accumulating epidemiological evidence implicates traumatic brain injury as a pathogenic agent in the development of Alzheimer's disease (AD). Considering the increase in the prevalence of both traumatic brain injury and AD in recent times, the possibility that brain trauma may provoke the early development of AD has important implications for health service planning, preventative efforts, and medico-legal compensation settlements. This paper evaluates the plausibility of the proposed link between traumatic brain injury and AD, largely by way of exploring a theoretical perspective advanced by Satz (1993) and considering recent contributions from the epidemiological, neuropathological, and biochemical literature that are pertinent to this issue. The literature reviewed provides sufficient support and empirical vindication to give credence to the proposed association between these two neuropsychological entities at the statistical, theoretical, and biological level.     

Family-Based Therapy for Adolescent Drug Abuse: Knowns and Unknowns

Family-based therapy is one of the most thoroughly studied treatments for adolescent drug abuse. Considerable empirical support exists for the efficacy of family-based therapy in curtailing adolescent drug use and cooccurring behavior problems. This article extends knowledge of the effects of family-based therapy for adolescent drug abuse by reviewing 16 controlled trials and 4 therapy process studies from a treatment development perspective. We articulate knowns and unknowns regarding the outcomes of treatment as well as the components, processes, mechanisms, moderators, and boundaries of effective family-based therapy for adolescent drug abuse. The review highlights areas of progress and future research needs within the specialty of family-based therapy for adolescent drug abuse.     

Global Progress I: Empirical Evidence for ongoing Increase in Quality-of-life

This paper argues that both the relativist and the pessimist critiques of the idea of progress are inadequate. Progress is defined as increase in global quality of life (QOL). Such QOL is intrinsically subjective, but not relative. It can be reliably measured through life satisfaction-type questions. The World Database of Happiness provides extensive data on social, economic and psychological factors that correlate with overall QOL. They include wealth, health, security, knowledge, freedom and equality. Various statistical data suggest that all these QOL indicators have undergone significant improvements during the last half century, in most of the world. This gives strong support to the thesis that progress objectively occurs.
