ABSTRACT: An analysis of 90 cases of criminal homicide followed by suicide in North Carolina, 1972 to 1977. Homicidal victim-offender relationships were investigated in regard to age, sex, race and whether victim and offender were member of the same family, friends, acquaintances, or strangers. These results were compared with victim-offender relationships in 994 criminal homicide cases in North Carolina in which offenders did not commit suicide. Married white males over 30 years were much more involved in homicide-suicide than they were in homicide alone. In these homicide-suicide cases, the victim was usually the spouse. Except for marital status, characteristics of homicide offenders who killed themselves resembled those of suicide-only individuals much more than those of homicide-only offenders. In the homicide-suicide cases, the killing of someone in close relationship to the offender, often a wife, appeared to be part of the evolving process of suicide. This clearly has implications for intervention into marital strife and also for immediate treatment of homicide offenders who kill spouses and other family members. 相似文献
A perspective on the controversy over the effects of early childhood intervention is provided. Gray, Ramsey, and Klaus' book is reviewed. The results of the study are commented upon, and implications for the continuing controversy about the effects of early childhood intervention are suggested. 相似文献
The traditional view of cerebral lateralization of various cognitive functions has been challenged by results from recent experimental and clinical studies. Evidence has been gathered to suggest that a seemingly unitized cognitive function can be further broken down into various processing subcomponents which are distributed across the two hemispheres. For instance, according to such a more complex conceptualization of cerebral lateralization, language is seen not as a unitary ability, but rather as a collection of syntactic, semantic, and prosodic components, with each lateralized in particular manners. In much the same way, the present study attempts to examine the cerebral lateralization patterns of the seemingly unitary visual perception process. In a visual half-field experiment, 20 normal subjects were asked to make same/different judgments to laterally presented arrays of stimuli of the same type as previously studied by Treisman and her colleagues in experiments attempting to separate the preattentive and attentive stages of visual perception. Hemispheric differences were obtained only in tasks requiring attentive processing (i.e., Treisman's glueing). Results indicate a local attentional strategy for the left hemisphere and a global attentional strategy for the right hemisphere. 相似文献
Background and Objectives: Chronically stressed individuals report deficits spanning cognitive and emotional functioning. However, limitations to clinical populations and measures of stress have impeded the generalisability and scope of results. This study investigated whether chronic stress predicted cognitive and emotional functioning, and whether these relationships differed between males and females, in a large representative sample of healthy participants.
Design: Cross-sectional study.
Method: 1883 healthy adults sampled from the Brain Resource International Database reported stress using the 21-item Depression Anxiety Stress Scales. Participants then completed a cognitive and emotional assessment battery (IntegNeuro), as well as questionnaires related to sleep, emotional functioning, and self-regulation.
Results: In contrast to previously reported results, chronic stress did not predict cognitive functioning. However, higher stress predicted a greater negativity bias and poorer social skills, confirming previous research identifying these links.
Conclusions: Cognitive deficits related to stress are absent in healthy participants when stress is measured using the 21-items Depression Anxiety Stress Scales. Identifying how chronic stress is associated with aspects of emotional functioning can lead to personalized interventions for individuals to better manage the negative outcomes resulting from stress. 相似文献
