The psychology of christian prayer: a review ofempirical research

This paper presents, discusses and evaluates empirical studies concerned with Christian prayer. These studies are classified within four main areas. The first area concerns what is known about the practice of prayer from empirical surveys and demonstrates that a much higher proportion of people pray privately than attend public places of worship. The second area concerns what is known about changing patterns of prayer during childhood and adolescence and argues that these changes need to be interpreted within the context of both developmental and social psychology. The third area concerns the subjective effects of prayer, beginning with Galton's early observations concerning the comparative longevity of the clergy (who are regarded as praying people) and including more recent studies of the psychological correlates of self-reported prayer, like personal well-being and purpose in life. It is concluded that, while such studies may demonstrate the beneficial nature of prayer, they cannot demonstrate the causal efficacy of prayer. The fourth area concerns the objective effects of prayer, beginning with Galton's early observations concerning the absence of comparative longevity among royalty (who are regarded as prayed for people) and including more recent studies of the growth correlates of prayer for pot plants. It is concluded that such studies currently provide contradictory evidence. It is recommended that further research in the field needs both to observe the strict criteria of objective empirical research and to be alert to theological nuances regarding the actual claims made for the efficacy of prayer within the community of believers.     

Contextualizing social identity in considerations of what it means to be a nurse

This paper describes research which provide the context for a discussion of how social representations can circumscribe identity possibilities and render feasible certain groups evaluations. Specifically, a research approach is advocated in which Social Identity and Social Representation Theory are integrated within single complementary paradigm, (Breakwell, 1993). A brief but critical examination of both theoretical traditions is ofered as the backdrop to this. A case study is described as a means of illustrating the unique potential of the integrated paradigm to predict and explain the meaning of social identity and the evaluations it affords. An investigation is then described involving 178 nurses ranging from Trainee to Charge Nurse status. Nurses were invited to use Q-sorts to describe the meaning of their group membership. As predicted from having identified the types of social representation of nurses available, two diferent identity orientations emerged: a communal-interpersonal (Patient Centred) and instrumental-intergroup (Professional Distinctiveness). The communal-interpersonal identity orientation was most typical of the lower status trainee nurses and also female nurses. In turn, higher status nurses and also male nurses, articulated a primarily instrumental-intergroup identity orientation. The evaluations signalled by group membership were also predictable from the identity orientations exhibited.     

Occupational conditions and workers' sense of community: Variations by gender and race

The literature is reviewed to define a sense of community in the workplace and to identify factors that may foster it. A model is developed and estimated with survey data from a culturally diverse sample of men and women performing lower-level jobs at a medium-sized manufacturing firm. Results of regression analyses are reported that correct for sample selection bias resulting from the lower response rates of minority workers. Findings suggest that well-designed jobs and supportive workplace relationships and policies are important in explaining workers' sense of community, defined as workers' perceptions of mutual commitment between employee and employer. Informal sources of support play a larger role in explaining men's sense of community, while formal sources of support are more important in explaining women's sense of community. Findings further suggest that African American workers, especially women, have a difficult time experiencing a sense of community at work. The authors thank the employees of Fel-Pro for their participation in this study and Melissa Roderick, Michael Sosin, and anonymous reviewers for their thoughtful comments. This research was funded by the Fel-Pro/Mecklenberger Foundation and the Lois and Samuel Silberman Fund.     

Evaluation of a “mental effort” hypothesis for correlations between cortical metabolism and intelligence

Previous research indicates that low scores on the Raven's Advanced Progressive Matrices (RAPM) test are associated with increased cortical glucose utilization during problem solving. We hypothesized that previous results may reflect the neurophysiological consequences of patterns of effort requirements; that is, high-effort expenditure from lower aptitude participants (for whom the problems are hard) and low-effort expenditure from higher aptitude participants (for whom the problems are easy). In this experiment, positron emission tomography (PET) data were gathered on participants (N = 28) who solved easy and hard problems that were tailored to the participants' own ability levels, thereby eliminating aptitude group differences in effort requirements. Contrary to previous results, high aptitude was associated with high cortical glucose use. Average aptitude participants showed diminished glucose use in the hard condition. A significant Group X Condition X Hemisphere Effect was also noted, with greater right hemisphere activation in the hard condition for the high-aptitude group. These results demonstrate that the relation of cerebral glucose use and cognitive ability is sensitive to participant and task selection.     

Gender and computer-mediated communication

A case study analyzed employees' attitudes toward, and experiences with, an intraorganizational electronic mail system. Results revealed that females perceived e-mail to be easier to use, more efficient, and more effective than males. They also gave higher ratings of appropriateness for using e-mail to transmit certain types of messages. Females (particularly managers) were more likely than their male counterparts to rely on co-workers to learn how to use e-mail. More females used the computer system for word processing, while more males and whites (who comprised 82.2% of the sample) had off-site connections to the computer system. No other distinctions were found regarding race—ethnicity. Implications for future research are discussed.The author is grateful to Karen Tracy, Robert Craig, and anonymous reviewers for their insights and suggestions.     

Gender and patterns of sexual risk taking in college students

The role that gender plays in influencing the prevalence and patterns of sexual risk taking was examined in 245 college students from two samples (about 60% of whom were White, 20% Asian, 10% Black, and 6% Hispanic). The sexual experiences of these students were analyzed for potential risk associated with type of partners or sexual practices. Consistent with previous findings, males engaged in more risk taking behaviors relevant to partner choice (e.g., more partners and more casual knowledge of partners) and sexual practices (e.g., lower levels of contraceptive use) than females. Gender differences in patterns of risk taking were also found: For females, potentially risky behavior in the partner domain was negatively related to risky behavior in the sexual practice domain, whereas for males, the domains were positively related. The results suggested that males engaged in greater risk taking across many domains, while females compensate for risk in one domain by lower risk in another.

Neuropsychological Features of Progressive Supranuclear Palsy

Progressive supranuclear palsy (PSP) is the epitome of a subcortical dementia process. Due to its relative rarity, there is only a small literature on the neuropsychological consequences of PSP. The findings to date demonstrate that PSP patients have dramatically slowed information processing and motor execution, rapid forgetting, problems in orienting attentional resources, and difficulty in planning and shifting conceptual sets. The pattern and severity of these deficits are unique to PSP and suggest that the study of PSP patients can provide a special insight into brain-behavior relations.
