High cognitive effort has been frequently related to better indices of motor learning through the study of many different paradigms. However, automaticity presumably invokes minimal cognitive processing but has often been related to high-level motor performance, which suggests a paradox. The objective of this study was to approach this paradox by examining the viability of the use of different cognitive strategies during practice and performance which promote the benefits of high cognitive effort and automaticity. Members of the university community (14 men and 15 women) divided into 3 groups practiced a discrete precision task. All participants completed four sessions totaling 320 trials and were tested on retention and transfer seven days later. Findings suggest that it is indeed possible to benefit from both effortful and minimal cognitive processing strategies and that they should be used complementarily.  相似文献

We tested whether individual differences in a component of early conscience mediated relations between parental discipline and externalizing behavior problems in 238 3.5-year-olds. Parents contributed assessments of discipline practices and child moral regulation. Observations of children's behavioral restraint supplemented parental reports. Parents and teachers reported on child externalizing symptoms. Parental induction, warm responsiveness, and less frequent use of physical punishment generally were associated with higher levels of moral regulation and fewer externalizing problems. Moreover, moral regulation partially mediated relationships between discipline and externalizing symptoms, with the clearest case of mediation involving induction. However, relationships were found for boys only. Results support a mediation model wherein inductive and physical discipline may influence the expression of boys' externalizing behavior through effects on conscience. Finally, results suggest that different developmental processes may be associated with early externalizing problems in boys and girls, and confirm that fathers' reports contribute to our understanding of the origins of child externalizing problems.  相似文献

The current article is an analysis of the research represented in American Journal of Community Psychology (AJCP) from 1993 to 1998, including a comparison to two previously published analytic reviews by Lounsbury et al. (J. W. Lounsbury, D. S. Leader, E. P. Meares, & M. P. Cook, 1980) and Speer et al. (P. Speer, A. Dey, P. Griggs, C. Gibson, B. Lubin, & J. Hughey, 1992), respectively. Observed trends are examined with references to major epistemological frameworks and methods used to define community psychology. Four guiding principles were examined to determine the representation of the epistemological frameworks of the articles published in the journal. The frameworks include social action, human diversity and cultural relativity, person–environmental fit, and methodological procedures. The results document the transition of community psychology from its early beginnings to an independent field conducting research consistent with the values articulated at the Swampscott Conference. This paper also comments on how well, after three decades of publication, the journal has served as a vehicle for improving community life.  相似文献

This study explored the applicability of previous research (obtained with groups of college-educated women) about the subjective experience of aging in midlife to men and less-educated people. Two-hundred fifty-nine men and women who graduated from a public high school in 1955-1957 retrospectively assessed their feelings of identity certainty, confident power, generativity, and concern about aging for their 60s, 40s, and 20s. Participants reported higher levels of identity certainty, confident power, and concern about aging at each age, and a leveling off of generativity in their 60s. There were some gender and social class differences. Although men and women recalled the same trajectory of these feelings, men reported higher levels of identity certainty and confident power across age. Non-college-educated men recalled the highest levels of concern about aging across age. We discuss how these findings add to our understanding of the experience of aging in these domains.  相似文献

Does intentional car following capture visual attention to the extent that driving may be impaired? We tested fifteen participants on a rudimentary driving simulator. Participants were either instructed to follow a vehicle ahead through a simulated version of London, or were given verbal instructions on where to turn during the route. The presence or absence of pedestrians, and the simulated time of the drive (day or night) were varied across the trials. Eye movements were recorded along with behavioural measures including give-way violations, give-way accidents, and kerb impacts. The results revealed that intentional car following reduced the spread of search and increased fixation durations, with a dramatic increase in the time spent processing the vehicle ahead (controlled for exposure). The effects were most pronounced during nighttime drives. During the car-following trials participants were also less aware of pedestrians, produced more give-way violations, and were involved in more give-way accidents. The results draw attention to the problems encountered during car following, and we relate this to the cognitive demands placed on drivers, especially police drivers who often engage in intentional car following and pursuits.  相似文献

Patients with social phobia report experiencing negative images of themselves performing poorly when in feared social situations. The present study investigates whether such negative self-imagery (based on memory of past social situations) contaminates social interactions. High socially anxious volunteers participated in two conversations with another volunteer (conversational partner). During one conversation, the socially anxious volunteers held in mind a negative self-image, and during the other they held in mind a less negative (control) self-image. As predicted, when holding the negative image the socially anxious volunteers felt more anxious, reported using more safety behaviours, believed that they performed more poorly, and showed greater overestimation of how poorly they came across (relative to ratings by the conversational partner). Conversational partners rated the socially anxious volunteers' performance as poorer in the negative image condition. Furthermore, the conversation was contaminated since both groups of participants rated its quality as poorer in the negative image condition.  相似文献

Evolutionary psychologists argue that human nature contains many discrete psychological adaptations. Each adaptation is theorized to have been functional in humans' ancestral past, and empirical evidence that an attribute is an adaptation can come from showing it possesses complexity, efficiency, universality, and other features of special design. In this article, we present a tutorial review of the evidentiary forms that evolutionary psychologists commonly use to document the existence of human adaptations. We also present a heuristic framework for integrating and evaluating cross-disciplinary evidence of adaptation. Pregnancy sickness, incest avoidance, men's desires for multiple sex partners, and an easily learned fear of snakes are evaluated as possible human adaptations using this framework. We conclude that future research and teaching in evolutionary psychology would benefit from more fully utilizing cross-disciplinary frameworks to evaluate evidence of human adaptation.  相似文献

Confirmatory factor analysis was used to test the scale structure of the Addiction Severity Index (ASI) in a sample of 1,802 substance abusers (43% alcohol dependent) with a concurrent psychiatric disorder (46% with mood disorders). The fit of the original composite score model based on the work of P. L. McGahan, J. A. Griffith, R. Parente, and A. T. McLellan (1990) was compared with the evaluation indices (EIs) developed by A. I. Alterman et al. (1998). The 5-dimensional model based on the EIs was an overall better fit to the data. Internal consistency (Cronbach's alpha) for the EIs ranged from.66 (family domain) to.75 (legal domain). The 5 EIs were moderately correlated (rs =.42-.72) with the interviewer severity ratings from the ASI. Evaluation studies involving concurrent disordered substance abusers should use the EIs as summary measures of change.  相似文献
