Rorschach responses in healthy, community dwelling older adults

Five predicted relationships between age and intellectual level and 16 Rorschach variables were examined through a cross-sectional analysis of 47 healthy, community-dwelling elderly men and women. Subjects were compared by age and intellectual level using gender, level of medication, and scores on the Geriatric Depression Scale (GDS) and the Geriatric Social Readjustment Questionnaire (GSRQ) as covariates. Screening tests for psychiatric and physical illness, recent life events, and hearing and vision loss were administered. In contrast to prior research suggesting changes in Rorschach scores with differences in age and intellectual level, only one significant difference was found for these variables. The data suggest that age and intellectual level may contribute less to Rorschach responses than was previously thought.     

Delineating generalized anxiety: A preliminary investigation

The present study examined the nature of generalized anxiety, which was defined as the constellation of symptoms listed as diagnostic criteria for generalized anxiety disorder in DSM-III-R. Generalized anxiety was assessed by means of a questionnaire that was especially constructed for this study. Although multidimensional scaling of symptoms reported by a clinically anxious sample produced orthogonal anxiety and panic dimensions, many symptoms were common to both dimensions. Whereas worry was found to be the cardinal feature of generalized anxiety, respiratory symptoms were found to associate closely with panic. These dimensions were replicated in a student sample. It is argued that while generalized anxiety symptoms constitute a unique dimension in the field of anxiety disorders, both panic and generalized anxiety may be linked with a basic anxiety response system. The findings also indicated that worry associated more closely with generalized anxiety than did apprehensive expectations. The heuristic value of the findings are discussed in light of the issue relating to an anxiety-panic continuum.     

Prevalence,Detection and Correlates of PTSD in the Primary Care Setting: A Systematic Review

Research suggests that posttraumatic stress disorder (PTSD) is common, debilitating and frequently associated with comorbid health conditions, including poor functioning, and increased health care utilization. This article systematically reviewed the empirical literature on PTSD in primary care settings, focusing on prevalence, detection and correlates. Twenty-seven studies were identified for inclusion. Current PTSD prevalence in primary care patients ranged widely between 2 % to 39 %, with significant heterogeneity in estimates explained by samples with different levels of trauma exposure. Six studies found detection of PTSD by primary care physicians (PCPs) ranged from 0 % to 52 %. Studies examining associations between PTSD and sociodemographic variables yielded equivocal results. High comorbidity was reported between PTSD and other psychiatric disorders including depression and anxiety, and PTSD was associated with functional impairment or disability. Exposure to multiple types of trauma also raised the risk of PTSD. While some studies indicated that primary care patients with PTSD report higher levels of substance and alcohol abuse, somatic symptoms, pain, health complaints, and healthcare utilization, other studies did not find these associations. This review proposes that primary care settings are important for the early detection of PTSD, which can be improved through indicated screening and PCP education.     

The Challenger Disaster And The Revival Of Rhetoric In Organizational Life

Explanations of the cause of the Challenger disaster by the Presidential Commission and by communication scholars are flawed. These explanations are characterized by a common tendency to emphasize the technical and procedural aspects of organizational life at the expense of the cognitive and ethical. Rightly construed, the Challenger disaster illustrates both the need for a revived art of rhetoric and the importance of putting in place the political and social conditions that make this art efficacious in furthering cognitive understanding and ethical conduct.     

Optimistic Bias Among Cigarette Smokers1

Smokers, unlike other populations engaging in risky behavior, readily acknowledge that tobacco use increases their susceptibility to smoking-related illness. This study used data from the Adult Use of Tobacco Survey to demonstrate that smokers, while acknowledging increased risk for illness, still show evidence of an optimistic bias in their perception of the hazards of their usual brand of cigarette. Optimism was assessed, first, by grouping respondents by perceived cigarette hazards (higher, lower, or about the same as others), and, second, by comparing Federal Trade Comission (FTC)-calculated and respondent-estimated cigarette tar levels. An optimistic bias was observed in all assessments. Perceived cigarette risk was not related to desire to stop smoking, if an easy way to do so were available, nor was it related to the number of previous quit attempts lasting one week or longer.     

Programming in natural language: A descriptive analysis

This study investigated the utility of natural language in specifying procedures. Performance of programmers was compared with that of nonprogrammers on two types of problems: a “real-world” ordering task and a computer like database search task. Programmers performed better than nonprogrammers in general, although overall differences between the groups were greater for the real-world problem domain. Analyses of protocols suggest that an unconstrained natural language programming environment is presently infeasible. Although constraints imposed in the problem specification do appear to improve performance, they alone are not sufficient to produce efficient natural language programming. It is argued that programming requires general problem solving strategies and that at least some aspects of such strategies may be dependent upon the specific language in which they are implemented.     

REM need in adolescents as indicated by resistance to REM deprivation.

The hypothesis that adolescents have an exceptionally strong need for REM sleep was tested by measuring their resistance to REM deprivation. Ten adolescents (aged 16 to 17 yr.) were compared with 12 young adults (aged 25 to 27 yr.) in a standard REM deprivation procedure. The adolescents had to be awakened significantly more times than the young adults; this is consistent with the hypothesis that adolescents have a greater need for REM sleep.     

Effects of classroom bilingualism on task‐shifting,verbal memory,and word learning in children

We examined the effects of classroom bilingual experience in children on an array of cognitive skills. Monolingual English‐speaking children were compared with children who spoke English as the native language and who had been exposed to Spanish in the context of dual‐immersion schooling for an average of 2 years. The groups were compared on a measure of non‐linguistic task‐shifting; measures of verbal short‐term and working memory; and measures of word learning. The two groups of children did not differ on measures of non‐linguistic task‐shifting and verbal short‐term memory. However, the classroom‐exposure bilingual group outperformed the monolingual group on the measure of verbal working memory and a measure of word learning. Together, these findings indicate that while exposure to a second language in a classroom setting may not be sufficient to engender changes in cognitive control, it can facilitate verbal memory and verbal learning.
