This paper identifies four attentional processes that increase efficiency and accuracy in repeated lexicographic tasks using an instructed strategy approach. We propose a framework to decompose attentional effort used to make a decision into four components: Orientation, Wrong Target, Duration, and Repetition. Orientation assesses attention to decision rules and the location of relevant information. Wrong Target measures wasted effort on unneeded information. Duration gauges time spent on each piece of needed information. Repetition measures the number of views on each relevant item. Greater Orientation is associated with lower effort in other components and increased accuracy. Repetition is most variable across individuals but generates the greatest improvement with practice. Duration is less affected by the other components and shows minimal improvement with experience. Finally, Wrong Target is similarly resistant to practice, but it is the only component strongly and positively associated with making errors. 相似文献

People can rehearse to-be-remembered locations either overtly, using eye movements, or covertly, using only shifts of spatial attention. The present study examined whether the effectiveness of these two strategies depends on environmental support for rehearsal. In Experiment 1, when environmental support (i.e., the array of possible locations) was present and participants could engage in overt rehearsal during retention intervals, longer intervals resulted in larger spans, whereas in Experiment 2, when support was present but participants could only engage in covert rehearsal, longer intervals resulted in smaller spans. When environmental support was absent, however, longer retention intervals resulted in smaller memory spans regardless of which rehearsal strategies were available. In Experiment 3, analyses of participants’ eye movements revealed that the presence of support increased participants’ fixations of to-be-remembered target locations more than fixations of non-targets, and that this was associated with better memory performance. Further, although the total time fixating targets increased, individual target fixations were actually briefer. Taken together, the present findings suggest that in the presence of environmental support, overt rehearsal is more effective than covert rehearsal at maintaining to-be-remembered locations in working memory, and that having more time for overt rehearsal can actually increase visuospatial memory spans. 相似文献

Lips (2012) deconstructs the standard methodological approaches to understanding the gender wage gap and shows that issues of gender pervade nearly every assumption of these models. In this commentary, we call attention to paradigmatic assumptions and theoretical approaches of the three most relevant social-science disciplines that deal with a parallel issue—occupational sex segregation—to demonstrate that scientific progress is facilitated by transparency in our disciplinary approaches to addressing gender disparities. Accordingly, the neoclassical economic approach to occupational sex segregation posits, among other things, self-selection in the development of human capital, such as choice of college major, as well as women’s tradeoffs in marriage vs. work-related capital as the drivers of occupational disparities. Progressive sociological approaches, such as feminist and Marxist sociology eschew these “supply-side” explanations in favor of examining “demand-side” explanations, particularly social forces that shape both employers’ beliefs about desirable worker attributes as well as the institutional structures that are created to support these views. Psychological approaches tend to address both supply-side (e.g., vocational preferences) and demand-side (e.g., stereotypes and bias) explanations. The aim of this commentary is to elucidate the paradigmatic approaches that each of the major social-science disciplines takes in understanding gender inequity issues in order to advance integrated research on these important social topics. 相似文献

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n?=?107; mean age?=?73.95?±?8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β?=?0.41; p?=?0.005) and EPI (β?=?0.44; p?=?0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β?=?–0.08; p?=?0.57) or EPI (β?=?0.23; p?=?0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers. 相似文献

Relationships between dispositional optimism and pessimism and the course of HIV infection, determined by changes in viral load and CD4 counts, were studied in a longitudinal cohort of 412 patients on antiretroviral therapy (ART). Multiple regression analyses controlling for baseline levels of disease status, ethnicity, and depressive symptoms demonstrated that higher pessimism at baseline was associated with higher viral load at follow-up (average of 18 months later). Optimism at baseline had a curvilinear relationship with CD4 counts at follow-up. Moderate levels of optimism at baseline predicted the highest CD4 counts at follow-up. Although optimism and pessimism were associated with specific health behaviors (e.g., ART adherence, cigarette use, drug use, dietary practices), none of these behaviors mediated the optimism/pessimism effects. The biologic and behavioral mediators of associations of personality variables with the course of treated HIV infection deserve continued investigation. 相似文献

Previous research indicated that a relationship existed between production of the Rorschach M response and inhibition of motor activity. The present study investigated this relationship under conditions which approximated those involved in the normal process of impulse control. Volunteer college students were used as subjects. Ss who engaged in a response inhibition task subsequently produced significantly more M responses than did Ss who had engaged in a noninhibitory task. This supported the hypothesis that M is an indication of the tendency to deal with impulses through fantasy. 相似文献

Underage drinking continues to be an important public health problem and a challenge to the substance abuse prevention field. Community-based interventions designed to more rigorously control underage access to alcohol through retailer education and greater enforcement of underage drinking laws have been advocated as potentially effective strategies to help address this problem, but studies designed to evaluate such interventions are sparse. To address this issue we conducted a randomized trial involving 36 communities to test the combined effectiveness of five interrelated intervention components designed to reduce underage access to alcohol. The intervention was found to be effective in reducing the likelihood that retail clerks would sell alcohol to underage-looking buyers, but did not reduce underage drinking or the perceived availability of alcohol among high school students. Post hoc analyses, however, revealed significant associations between the level of underage drinking law enforcement in the intervention communities and reductions in both 30-day use of alcohol and binge drinking. The findings highlight the difficulty in reducing youth drinking even when efforts to curtail retail access are successful. Study findings also suggest that high intensity implementation of underage drinking law enforcement can reduce underage drinking. Any such effects of enhanced enforcement on underage drinking appear to be more directly attributable to an increase in perceived likelihood of enforcement and the resultant perceived inconveniences and/or sanctions to potential drinkers, than to a reduction in access to alcohol per se. 相似文献

Three mirror tracing experiments were conducted to investigate the connection between perception and motor behavior. In the first experiment, some subjects traced a hex-maze, other subjects traced a hex-maze after observing a model trace, others traced a hex-maze after reading instructions on mirror images, and others traced a hex-maze after having observed a model and heard the instructions. There were no significant differences between the groups' error scores, but their time scores differed significantly, although not always in the predicted direction. In Experiment 2, the subjects were to trace selected letters of the alphabet. Error scores for the second experiment did not differ much from those for the first experiment. In Experiment 3, the experimenter gave each subject commands for the correct directions of movement, using the subject's body as a frame of reference. There was little improvement in motor performance. These results suggest that the visual information presented in the mirror captured the subjects' attention and blocked their motor tracing program. 相似文献

Abstract A number of studies have been reported recently evaluating the effects of one or another form of intervention based on Adlerian principles (Freeman, 1975; Croake and Burness, 1976; Berrett, 1975; McKay, 1976; see also McDonough, 1976, for a review of other studies). Unfortunately, there are a number of problems in attempting to draw any general conclusions from these studies. First, a number of different types of Adlerian-based programs have been included, such as mother study groups, undefined parent study groups, and so on. Second, many of the studies were uncontrolled so that statements regarding the causes of any changes cannot be inferred. Third, many of the studies did not utilize adequate measures of child behavior (positive changes in which are an important goal of Adlerian family education programs), and instead relied on changes in parent attitudes. 相似文献

Misuse of alcohol and drugs is widespread in modern society with the associated emotional and physical tolls on individuals, couples, and families. Yet, many therapists do not assess nor address substance misuse when clients do not identify it as a presenting problem. This article presents an overview of the literature on key aspects of couples and substance use and makes important clinical recommendations for mental health professionals who work with couples that struggle with substance use. 相似文献
