Divergent thinking in Alzheimer's and frontotemporal dementia

Twenty-three patients with mild dementia of the Alzheimer's type (DAT) or frontotemporal type (DFT) and age- and education-matched control subjects were administered tests of complex fluency involving divergent thinking and tests of letter, category, and figural fluency. The tests of complex fluency discriminated the dementia patients from control subjects more strongly than did the other fluency tests. The results suggest that divergent thinking as assessed by complex fluency tests is a cognitive domain that is impaired early in the course of dementia. The sensitivity of complex fluency tests compared to that of letter, category, and figural fluency tests may be related to greater demands for conceptualization in relating stimulus attributes to function and greater demands for flexible thinking during self-directed search processes.     

Automatic activation of categorical and abstract analogical relations in analogical reasoning

We examined activation of concepts during analogical reasoning. Subjects made either analogical judgments or categorical judgments about four-word sets. After each four-word set, they named the ink color of a single word in a modified Stroop task. Words that referred to category relations were primed (as indicated by longer response times on Stroop color naming) subsequent to analogical judgments and categorical judgments. This finding suggests that activation of category concepts plays a fundamental role in analogical thinking. When colored words referred to analogical relations, priming occurred subsequent to analogical judgments, but not to categorical judgments, even though identical four-word stimuli were used for both types of judgments. This finding lends empirical support to the hypothesis that, when people comprehend the analogy between two items, they activate an abstract analogical relation that is distinct from the specific content items that compose the analogy.     

An ethics of expertise based on informed consent

Ethicists widely accept the notion that scientists have moral responsibilities to benefit society at large. The dissemination of scientific information to the public and its political representatives is central to many of the ways in which scientists serve society. Unfortunately, the task of providing information can often give rise to moral quandaries when scientific experts participate in politically charged debates over issues that are fraught with uncertainty. This paper develops a theoretical framework for an “ethics of expertise” (EOE) based on the notion that scientists have responsibilities to provide information in a way that promotes autonomous decision-making on the part of the public and its representatives. Moreover, insofar as the principle of informed consent has developed in biomedical ethics as a way for physicians to promote autonomous decision-making on the part of their patients, this paper suggests that the informed-consent concept may suggest a set of criteria and guidelines that can help scientists to fulfill their similar ethical responsibilities to the public. In order to illustrate how the resulting EOE could provide practical guidance for scientific experts, the paper examines a case study involving the dissemination of information about the low-dose biological effects of toxic chemicals and carcinogens.     

Tests of multiplicative models in psychology: a case study using the unified theory of implicit attitudes, stereotypes, self-esteem, and self-concept

Theories that posit multiplicative relationships between variables are common in psychology. A. G. Greenwald et al. recently presented a theory that explicated relationships between group identification, group attitudes, and self-esteem. Their theory posits a multiplicative relationship between concepts when predicting a criterion variable. Greenwald et al. suggested analytic strategies to test their multiplicative model that researchers might assume are appropriate for testing multiplicative models more generally. The theory and analytic strategies of Greenwald et al. are used as a case study to show the strong measurement assumptions that underlie certain tests of multiplicative models. It is shown that the approach used by Greenwald et al. can lead to declarations of theoretical support when the theory is wrong as well as rejection of the theory when the theory is correct. A simple strategy for testing multiplicative models that makes weaker measurement assumptions than the strategy proposed by Greenwald et al. is suggested and discussed.     

A national survey of hospital directors' views about the importance of various chaplain roles: differences among disciplines and types of hospitals

A national random sample of hospital directors was asked to rate the importance of seven categories of chaplain roles and functions: 246 nursing directors, 267 social services directors, 307 medical directors, and 611 pastoral care directors. All four groups rated end-of-life care, prayer, and emotional support as being between very important and extremely important. Other roles, including consultation, advocacy, community outreach, and religious services and rituals were rated significantly less important. Significant differences were found across disciplines and hospital settings (general, psychiatric, etc.). Medical directors rated most chaplain roles lower than other directors did, and directors in psychiatric hospitals rated all roles, except religious services/rituals, lower than their counterparts in other types of hospitals. The importance that directors accorded to all the chaplain roles examined was also influenced by their own spirituality and religiosity, as well as the religious affiliation of their institution.     

Compassion fatigue and burnout among Rabbis working as chaplains

Compassion Fatigue, Compassion Satisfaction, and Burnout were studied in a convenience sample of 66 male and female Rabbis who work as chaplains and attended the annual conference of the National Association of Jewish Chaplains (NAJC) in 2002. Although Compassion Fatigue and Burnout were low among the survey participants, both measures were significantly higher among the women in the sample. Compassion Fatigue was also higher among chaplains who were divorced, and it increased with the number of hours per week the chaplains spent working with trauma victims or their families (r = .25, p<.05). Hierarchical multiple regression was performed to determine the influence of six professional and five personal variables on each of the three dependent variables. Four professional variables accounted for 19.5% of the variation and three personal variables accounted for 20.3% of the variation in Compassion Fatigue. Attempts to predict Burnout and Compassion Satisfaction were far less successful. Burnout was predicted by only two variables (i.e. age and years as a Rabbi), which accounted for just 18.4% of the variance in Burnout scores. Age was the only variable found to have a significant effect on Compassion Satisfaction, and its effect was positive. The implications of the findings are discussed.     

Violence and minority youth: the effects of risk and asset factors on fighting among African American children and adolescents

This cross-sectional study examined risk and asset factors thought to be associated with fighting among a sample of 1,642 African American children and adolescents in a central Alabama school district. Results show that poor grades, parental abuse, and gang affiliation were significant risk factors associated with higher frequency of fighting. Results also show that parental monitoring and being happy at school were associated with lower frequency of fighting, suggesting the importance of continued support for outreach to parents and further efforts to reduce or eliminate the community factors that promote proliferation of gangs. Programs, either for an entire community or a school system within a community, must be sensitive to the specific risks, assets, and outcomes of that environment so that prevention and intervention are sensitive to cultural, environmental, and demographic distinctions in target populations.     

Proactive personality and the successful job search: a field investigation with college graduates

The current article tests a model of proactive personality and job search success with a sample of 180 graduating college students. Using structural equation modeling, the authors tested a theoretical model that specified the relations among proactive personality, job search self-efficacy, job search behaviors, job search effort, and job search outcomes. Job seekers were surveyed at 2 separate points in time, once 3-4 months prior to graduation and once 2-3 months following graduation. The results suggest that proactive personality (a) significantly influenced the success of college graduates' job search, (b) was partially mediated through job search self-efficacy and job search behavior, and (c) was independent of self-esteem and conscientiousness. The findings are discussed in terms of their general implications for understanding the nature of the process through which distal personality factors, such as proactive personality, affect the nature and success of an individual's job search.     

Verbal coding and the storage of form-position associations in visual-spatial short-term memory

Short-term memory for form-position associations was assessed using an object relocation task. Participants attempted to remember the positions of either three or five Japanese Kanji characters, presented on a computer monitor. Following a short blank interval, participants were presented with 2 alternative Kanji, only 1 of which was present in the initial stimulus, and the set of locations occupied in the initial stimulus. They attempted to select the correct item and relocate it back to its original position. The proportion of correct item selections showed effects of both articulatory suppression and memory load. In contrast, the conditional probability of location given a correct item selection showed an effect of load but no effect of suppression. These results are consistent with the proposal that access to visual memory is aided by verbal recoding, but that there is no verbal contribution to memory for the association between form and position.     

Beyond the optimal contact strategy: a reality check for the contact hypothesis

The contact hypothesis proposes that interaction between members of different groups reduces intergroup prejudice if--and only if--certain optimal conditions are present. For over 50 years, research using this framework has explored the boundary conditions for ideal contact and has guided interventions to promote desegregation. Although supporting the contact hypothesis in principle, the authors critique some research practices that have come to dominate the field: (a) the prioritizing of the study of interactions occurring under rarefied conditions, (b) the reformulation of lay understandings of contact in terms of a generic typology of ideal dimensions, and (c) the use of shifts in personal prejudice as the primary measure of outcome. The authors argue that these practices have limited the contact hypothesis both as an explanation of the intergroup dynamics of desegregation and as a framework for promoting social psychological change. In so arguing, the authors look toward a complementary program of research on contact and desegregation.
