It is disputed whether onsets capture spatial attention either in a purely stimulus-driven fashion or only when they are contingent on one's attentional set. According to the latter assumption, interference from irrelevant onsets may result from nonspatial filtering costs. In the present study, we used inhibition of return (IOR) as a marker for spatial attention. IOR occurs mainly for locations that attention has visited before. Participants searched for a red object among white objects. An attentional set for redness was demonstrated by a spatial validity effect of red cues on response times. However, a stronger validity effect was found for irrelevant white onsets, which slowed responses when the onset contained a distractor, but speeded them when the onset contained a target. Most importantly, this onset benefit for targets turned into a deficit at longer SOAs, indicating IOR. We conclude that onset distractors capture spatial attention regardless of the observer's attentional set. 相似文献

ABSTRACTThis cross-sectional field study examines the influence of employee and spousal characteristics on employees’ career-related motivations in dual ladder systems. We go beyond “constraints-based” explanations of spousal influence and focus on the degree to which the spouse has aspirations for the focal employee’s career – referred to as spousal career aspirations. Using a dyadic study design, we tested a model that specifies the influence of both partners’ career salience and materialism on an employee’s motivation for a particular career path: as manager or technical specialist. According to survey responses from a matched sample of 207 employees and their spouses, the spouse’s career salience and materialism (the latter only for women) were associated with higher levels of spousal career aspirations. In turn, those employees whose spouses aspired for them to have a career were less motivated to obtain a specialist position. Employees’ own career salience was positively associated with their motivation for a managerial position and, in combination with high levels of spousal career aspirations, pulled employees away from a career on the technical ladder. Our results shed light on the family-relatedness of career decisions and have notable implications for dual ladder organizations. 相似文献

Abstract The question of whether one should use subjective rather than “objective” assessments of job characteristics is still the subject of a vigorous discussion in analytical studies of jobs and in job design. In nursing work situations, too, the attention of managers and researchers for such studies is growing. In this article the results of a study are presented in which a comparison is made between two kinds of assessments: job characteristics as judged by task performers (nurses) and job characteristics as judged by non-task performers (nursing management). Differences and agreements between mean scores as well as between correlations with dependent variables like job satisfaction were analysed. Most agreement seems to be on the ratings of “complexity and difficulty”, “work pressure”, and “promotion and growth opportunities”. As to “feedback and clarity”, “autonomy”, and “patient caring opportunities”, differences between the ratings have been found. It appears that a larger number of correlations between the nurse-rated job characteristics and the reaction variables is found to be statistically significant than between the management-rated job characteristics and the reaction variables. Social, organizational, and methodological reasons for the observed differences are put forward. 相似文献

Since their discovery in the early 1990s, mirror neurons have been proposed to be related to many social‐communicative abilities, such as imitation. However, research into the early manifestations of the putative neural mirroring system and its role in early social development is still inconclusive. In the current EEG study, mu suppression, generally thought to reflect activity in neural mirroring systems was investigated in 18‐ to 30‐month‐olds during the observation of object manipulations as well as mimicked actions. EEG power data recorded from frontal, central, and parietal electrodes were analysed. As predicted, based on previous research, mu wave suppression was found over central electrodes during action observation and execution. In addition, a similar suppression was found during the observation of intransitive, mimicked hand movements. To a lesser extent, the results also showed mu suppression at parietal electrode sites, over all three conditions. Mu wave suppression during the observation of hand movements and during the execution of actions was significantly correlated with quality of imitation, but not with age or language level. 相似文献

The role of counselling and psychotherapy services in relation to the needs of economically disadvantaged individuals has been largely neglected in the recent research literature. Although a small number of theoretical papers and case analyses have been published, there is an absence of studies that examine the effectiveness of counselling with this client group. The present paper reports on a naturalistic outcome study of the effectiveness of time-limited counselling (seven sessions) with low-income clients. Analysis of pre-counselling, postcounselling and follow-up measures of mental health and problem ratings indicated levels of change equivalent to those achieved in controlled studies of counselling and psychotherapy with other client groups. Factors influencing the effectiveness of counselling included gender and employment status. Qualitative client reports suggested that the main benefits experienced by clients were in the areas of self-understanding and self-belief. For illustrative purposes, data from low-income clients are compared with results from employee counselling clients receiving a similar service. The implications of these findings for further research are discussed. 相似文献

ABSTRACT The present paper investigates the effects of age, sex, and cognitive factors on temporal-order perception. Nine temporal-order tasks were employed using two and four stimuli presented in the auditory and visual modalities. Significantly increased temporal-order thresholds (TOT) in the elderly were found for almost all tasks, while sex differences were only observed for two tasks. Multiple regression analyses show that the performance on most temporal-order tasks can be predicted by cognitive factors, such as speed of fluid reasoning, short-term memory, and attention. However, age was a significant predictor of TOT in three tasks using visual stimuli. We conclude (1) that age-related differences can often be attributed to cognitive factors involved in temporal-order perception, and (2) that the concept of temporal-order perception is more complex than implied by the current models. 相似文献

Performing an intended action when it needs to be withheld, for example, when temporarily prescribed medication is incompatible with the other medication, is referred to as commission errors of prospective memory (PM). While recent research indicates that older adults are especially prone to commission errors for finished intentions, there is a lack of research on the effects of aging on commission errors for still active intentions. The present research investigates conditions which might contribute to older adults’ propensity to perform planned intentions under inappropriate conditions. Specifically, disproportionally higher rates of commission errors for still active intentions were observed in older than in younger adults with both salient (Experiment 1) and non-salient (Experiment 2) target cues. Practicing the PM task in Experiment 2, however, helped execution of the intended action in terms of higher PM performance at faster ongoing-task response times but did not increase the rate of commission errors. The results have important implications for the understanding of older adults’ PM commission errors and the processes involved in these errors. 相似文献

The aim of this study was to do a first phase screening of psychometric properties of various scales measuring facets of psychological well-being so as to address further questions in the FORT 1 project (FORT 1 = Clarifying the nature of psychological strengths). All scales (except one) were developed in a Western context, and measure facets of cognitive, affective, conative, social, and spiritual psychological well-being. As it could not be assumed that scales are valid in South African contexts, a broad screening of their psychometric properties was necessary before specific questions could be adressed. A convenience sample (N=514) including white (n=384) and black (n=130) students and adults from the North West Province and Gauteng areas completed all questionnaires. Psychometric properties of scales varied from acceptable to unacceptable for use in a specific subgroup. 相似文献

Previously, social and cognitive abilities of dogs have been studied within behavioral experiments, but the neural processing underlying the cognitive events remains to be clarified. Here, we employed completely non-invasive scalp-electroencephalography in studying the neural correlates of the visual cognition of dogs. We measured visual event-related potentials (ERPs) of eight dogs while they observed images of dog and human faces presented on a computer screen. The dogs were trained to lie still with positive operant conditioning, and they were neither mechanically restrained nor sedated during the measurements. The ERPs corresponding to early visual processing of dogs were detectable at 75–100 ms from the stimulus onset in individual dogs, and the group-level data of the 8 dogs differed significantly from zero bilaterally at around 75 ms at the most posterior sensors. Additionally, we detected differences between the responses to human and dog faces in the posterior sensors at 75–100 ms and in the anterior sensors at 350–400 ms. To our knowledge, this is the first illustration of completely non-invasively measured visual brain responses both in individual dogs and within a group-level study, using ecologically valid visual stimuli. The results of the present study validate the feasibility of non-invasive ERP measurements in studies with dogs, and the study is expected to pave the way for further neurocognitive studies in dogs. 相似文献

Part 1 of this paper examined some of the ways in which individual therapy, by assisting in the development of a more cohesive sense of self in the individual, inevitably has an impact on the individual's relationships, especially their relationship with a partner. This paper approaches the topic of the significance of ‘the self’ in the couple relationship from an alternative direction. It focuses on the significance of ‘the self’ for couples therapy, and argues that couples therapy may sometimes need to include therapeutic work with one partner to facilitate change in the relationship. In both parts of the paper, a conceptualization of the couple relationship as ‘a transitional space’ is central. 相似文献
