Castel and colleagues (Percept Psychophys 65(6):970–981, 2003) proposed that visuospatial working memory is needed to retain and update the irrelevant but attended location in an inhibition
of return (IOR) procedure. In a series of three experiments, we re-examined this hypothesis by loading visuospatial working
memory and manipulating the timing of encoding. When the visuospatial memory items were presented right after the cue, as
in Castel et al. (Percept Psychophys 65(6):970–981, 2003), we replicated the lack of IOR in the dual-task condition (Experiment 1). However, when we presented the visuospatial memory
items before the spatial cue, to control for retroactive interference in encoding, we found robust IOR effects (Experiment
2); the effect remained strong even when participants were prevented from using verbal labels to rehearse the memory material
(Experiment 3). We conclude that IOR does not seem to depend on retaining the position of the irrelevant cue in visuospatial
working memory. 相似文献

This paper deals with benchmark‐based portfolio choice for buy‐and‐hold strategies of investing. Multiple benchmarks for returns are considered, which is more realistic than taking a unique benchmark – a unique aspiration difficult to select in practice among the various aspirations for returns that the investor has in mind. Portfolio selection with multiple benchmarks leads to a multi‐objective problem, which is addressed by mean value – stochastic goal programming. In particular, two benchmarks are considered, which involves two goals. Weights for goals depend on investor's preferences and Arrow's absolute risk aversion coefficients. An efficient frontier of portfolios is obtained. Advantages of this stochastic method in our context are as follows: (i) Mean value‐stochastic goal programming relies on classical utility theory under uncertainty and Arrow's absolute risk aversion, which ensures soundness and strictness, and (ii) the numerical model is easily solved by using available software such as mean–variance software. Numerical results are tabulated and discussed. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

The present study examines whether daily recovery inhibiting and enhancing conditions predict day-levels of work-family conflict (WFC), work-family facilitation (WFF), exhaustion and vigor. Forty-nine individuals from various professional backgrounds in Spain provided questionnaire and daily survey measures over a period of five working days. Multilevel analyses showed that day-levels of work pressure and recovery after breaks at work significantly predicted WFC and exhaustion, and WFF and vigor, respectively. Moreover, daily fluctuations in expression of emotions had different effects depending on the expressed content (negative or positive) and the setting where it took place (work or home). Furthermore, additional analyses provided some evidence for a moderating role of expression of emotions at work on the relationship between recovery inhibiting and enhancing conditions and exhaustion. These findings reveal practical implications for individuals and organizations and suggest possible avenues for future research. 相似文献

The effects of power legitimacy on self-regulation during goal pursuit were examined. Study 1 focused on goal-setting and goal-striving. Specifically, it examined how much time legitimate and illegitimate powerless individuals needed to set goals, and how many means they generated to pursue these goals. Study 2 examined persistence in the face of difficulties. Consistently across these studies illegitimacy improved self-regulation in powerless individuals. Illegitimate powerless individuals behaved similarly as control participants. They took less time to decide on a course of action, used more flexible means to strive for goals, and persisted longer in the face of difficulties, compared to their legitimate counterparts. The implications of these findings are discussed. 相似文献

Perfectionism has been identified as a common concern among clients who seek counseling services. For more than 20 years, the Frost Multidimensional Perfectionism Scale (F-MPS) has been used extensively to measure the construct of individuals' perfectionism. The current study used reliability generalization to identify the average score reliability as well as variables explaining the variability of score reliability. Typical reliability across subscale scores ranged from .71 to.86 with the Doubt about Action subscale showing the least variability and the Organization subscale showing the most. In addition, sex, language, and standard deviation of the scale had statistically significant relations to reliability estimates. 相似文献

The Remote Associates Test is a well‐established measure, frequently used to assess individuals’ creative abilities, as a function of the ability to elicit remote associates. The nature of the involved associative processes is still poorly understood. This hampers a deeper understanding of the creative process, rendering it difficult to determine what factors are controlled for, when the RAT is employed. We report an experiment that sheds further light on the nature of the associative process by manipulating (a) the frequency with which a pair of items are associated as associative strength, and (b) the probability of reaching the answer given the strength and the spread. Experimental results indicate a clear and surprisingly separate influence of frequency and probability on accuracy and response times. Frequency and probability both are thus factors that need to be included in the modeling process and controlled for when using the RAT to assess creativity. 相似文献

Objective: To assess age-related changes in postural sway during sit-to-stand (STS) in typical children (TC) and children with mild cerebral palsy (CP). Methods: Thirty-five TC and 23 children with mild CP were allocated in four different age groups: 5–6, 7–9, 10–12, and 13–15 years; they all performed STS movements over a force plate. Anterior-posterior and medial-lateral amplitude of center of pressure (CoP) displacement, area and velocity of CoP sway were analyzed and compared between the age groups for TC and children with CP. Results: TC at 5 to 6 years of age showed higher values of anterior-posterior CoP displacement and Area of CoP sway than at 10–12 years, during the stabilization phase. There were no age-related changes for CP. Conclusion: TC change their postural sway during the last STS phase over the years, reducing their body sway. Children with CP did not show age-related changes in sway during STS, reflecting a distinct rhythm of postural control development in this population. 相似文献

According to general strain theory (GST), life stressors, or strains, lead to different types of negative emotions, some of which increase the likelihood of maladaptive coping. A considerable body of research testing GST focuses on anger and depression as manifestations of negative emotionality. Less research considers other types of negative emotions (e.g., anxiety and envy). The current study addresses this void in the literature through the use of surveys administered to a university-based sample. We also consider whether the effects of negative emotions vary by sex. The implications of our findings for theory, research, and mental health providers are discussed. 相似文献

In order to determine whether expenditures for mental health could be reduced and quality improved, Congress mandated that the Department of Defense conduct a demonstration project utilizing a wraparound mental health service system for child and adolescent military dependents. A longitudinal quasiexperimental design was used to evaluate the cost-effectiveness of the demonstration. The results showed that children in the Wraparound Group received more wraparound services than those in the treatment as usual (TAU) Comparison Group. These services included case management, in-home treatment, and other nontraditional services. The Demonstration also provided better continuity of care. Multiple methods were used to investigate the impact of wraparound. Both groups showed some improvement on some measures but there were no differences between the groups in functioning, symptoms, life satisfaction, positive functioning, or sentinel events. Regardless of which statistical model was used to estimate costs, the Demonstration was also more expensive. The higher level of expenditures for the Wraparound group was a result of some expensive traditional care and the addition of nontraditional services. Several possible explanations of these results are provided. 相似文献

In the context of addiction research, positive recovery outcomes are affected by the quality of people's social interactions and perhaps to an even greater extent, by the defining norms of the groups they identify with—that is, using versus recovery groups. Here, we examine the role of online supportive networks in the process of recovery from alcohol addiction. We analyse the relationship between negative and positive aspects of recovery capital (i.e., self‐stigma, and respectively, positive recovery identity and self‐efficacy) as they relate to well‐being outcomes among alcohol users in an online recovery support group. Based on a computerised linguistic analysis of the naturally occurring data extracted from an online recovery support group (i.e., 257 posts made by 237 group members), we found that self‐stigma negatively predicts self‐efficacy and well‐being, and social identification with a recovery identity mediates these relationships. Overall, these findings highlight that positive engagement with supportive recovery networks is central to an effective and sustainable recovery. 相似文献
