Violent death in the West: suicide and homicide in New Mexico, 1958-1987

We examined New Mexico vital statistics data for suicides and homicides among the state's Hispanics, Native Americans, and non-Hispanic whites collected from 1958 to 1987. We found high age-adjusted rates for both suicides and homicides among Hispanic and Native American males, in comparison with rates for non-Hispanic white males. Suicide rates among Native American women were comparatively low, contrasting with their high homicide rates. Homicide rates for males in all three ethnic groups increased substantially over the 30-year study period. We conclude that death from violent causes, both suicide and homicide, is a major public health problem in New Mexico, and disproportionately affects minority males.     

School psychologists' services in special education programs

Reviews school psychologists' services in special education programs. Fifty-eight credentialed school psychologists in 10 school districts were interviewed individually about background and training, professional duties, favored clinical techniques, and opinions and recommendations for improved services. According to self-reports, the bulk of time was devoted to activities directly related to assessment of pupils with little involvement in research, in-service training, or other clinical activities. Professional association memberships were primarily local. Assessment techniques tended to be limited to a few standardized tests. Overall findings support sample psychologists' expressed concerns as to need for changes in preservice and in-service training.     

Difficulties in assessing depressive-like reactions to chronic severe external stress as exemplified by spouse caregivers of Alzheimer patients

Problems in making differential diagnoses and severity ratings of depressive-like reactions in chronically, heavily stressed persons are described. These assessment concerns are especially pertinent to older persons. The assessment concern discussed relates to difficulties in determining the extent to which stress reactions are inevitable consequences of stressor demands versus excessive pathological reactions versus natural manifestations of aging. The newly revised criteria of the Diagnostic and Statistical Manual of Mental Disorders, 3rd edition (DSM-III-R) and its associated structured interviews do not lessen the difficulties described. However, they reflect progress in specifying the amount of cross-sectional and longitudinal consistency required before maladaptive behaviours meet diagnostic and/or severity criteria as pathological indicators. Stressor level is important among the criteria for the less severe DSM-III-R depression-related disorders, but the specific response demands of the stressors are ignored. By contrast, biomedical factors are consistently given significant weight. To clarify these matters, the five DSM-III-R diagnostic axes, depressive diagnostic criteria, and associated structured interviews for eliciting relevant data are reviewed.     

The influence of context and UCS intensity on the UCS preexposure effect in a flavor aversion paradigm

Three studies were conducted to evaluate the influence of environmental context and UCS preexposure intensity on the acquisition of a flavor aversion. In the first study, rats were exposed to two UCS-alone presentations at one of three dose levels of LiCl. The rats were given the two UCS preexposures in one of two contexts (familiar or novel). Following the UCS-alone treatment, all of the subjects received two pairings of sucrose and LiCl (1.25 meq) in the familiar context. Animals receiving UCS preexposures in the same context as used during conditioning consumed significantly more sucrose than did saline control animals. In contrast, the influence of prior UCS preexposure was not evident when UCS preexposure was experienced in a context different from that experienced during conditioning. In Experiment 2, all animal received UCS preexposure and conditioning in the novel room. Animals received either two or four preexposures at 0, 1.25, or 3.75 meq dose of LiCl. Two UCS preexposures at 3.75 meq dose produced a stronger UCS preexposure effect than did the 1.25 meq dose. Animals in Experiment 3 received two exposures to either 0-, 1.25-, or 3.75-meq LiCl in one of two contexts, followed by conditioning with the 1.25-meq LiCl dose in the same context as preexposure. Greater UCS interference occurred in animals preexposed to LiCl in the novel rather than familiar environment, with no specific dose effects in either context. These observations are discussed in terms of context blocking and generalization decrement models of the UCS preexposure effect.     

Psychosocial Predictors of Change in Cigarette Smoking

Over a period of 6 months, factors related to change in cigarette smoking were investigated in a group of 250 adult outpatients, all of whom smoked at the time of enrollment in the study. Among the variables tested were demographic, social, and situational factors, beliefs about the health effects of smoking and difficulty of quitting, and intentions regarding future smoking. Information was gathered at baseline and the first and sixth months by means of telephone interviews. Relative to smoking at 6 months, intention, education, and professional advice made independent contributions to cessation. The processes of quitting were examined in more detail. Attempting to quit was related to intention, professional advice, level of smoking, and social cues to smoke. Among those who tried to stop, difficulty with urges to smoke, and education affected success versus failure. Earlier success related to less anxiety and tension, and to less difficulty in not smoking when in negative situations. The findings suggest that a complex set of social and cognitive factors affect change in smoking behavior, and that somewhat different factors are operative at different stages.     

Semantic context effects in visual word recognition: An analysis of semantic strategies

Using a procedure that isolates the facilitatory and interfering effects of a semantic context, the present study examines two distinct patterns of context effects. One pattern shows a dominance of facilitation for target words in a related context, and the other pattern shows a dominance of interference for target words in an unrelated context. The controlling factor seems to be the overall characteristics of the stimulus list. For materials that include semantic relationships that are consistent in the strength of the relationships, facilitation dominance obtains. For materials that include a wide range of semantic relationship strengths, interference dominance results. These two patterns of facilitation and interference are attributed to two semantic strategies available to subjects for using context information. The explication of the strategies includes a theoretical treatment of the present data.
