Perceptual load is a key determinant of distraction by task-irrelevant stimuli (e.g., Lavie, N. (2005). Distracted and confused?: Selective attention under load. Trends in Cognitive Sciences, 9, 75-82). Here we establish the role of perceptual load in determining an internal form of distraction by task-unrelated thoughts (TUTs or “mind-wandering”).Four experiments demonstrated reduced frequency of TUTs with high compared to low perceptual load in a visual-search task. Alternative accounts in terms of increased demands on responses, verbal working memory or motivation were ruled out and clear effects of load were found for unintentional TUTs. Individual differences in load effects on internal (TUTs) and external (response-competition) distractors were correlated. These results suggest that exhausting attentional capacity in task-relevant processing under high perceptual load can reduce processing of task-irrelevant information from external and internal sources alike.  相似文献

This study tested whether the aging of executive functioning is linked to the decline in planning performance. Participants were divided into three groups: group 1 composed of 15 adults with a mean age of 22.7 years, group 2 composed of 15 adults with a mean age of 68.1 years and group 3 composed of 16 adults with a mean age of 78.75 years. Each participant took tests for shifting, inhibition, updating and processing speed. Planning was evaluated by the Tower of Hanoi task with 3 and 4 disks. Analyses of variance showed a main age effect on the many executive functioning and planning measures assessed. Analyses of regression indicated that combined processing speed and shifting accounted for 58.33% of performance on the 3-disk version, while processing speed accounted for only 36.86% of performance on the 4-disk version. These results are discussed in relation to two levels of the planning process: formulation and execution.  相似文献

This study examines the role of individual team members' positive mood and perceived team feedback for their team-directed learning behaviour. Results obtained in a sample of 186 members from 27 work teams showed that positive mood was positively associated with team-directed learning behaviour if individual members perceived that the feedback they received was based on the performance of the team as a whole, but not if they perceived such team feedback to be lacking. Moreover, teams were found to be more innovative to the extent that their members, on average, engaged in team-directed learning behaviour to a greater extent. These results offer new insights into the micro-foundations of team learning. Our findings explicate why the contributions of individual members to their team's learning may differ and suggest that, if managed effectively, members' positive mood may be an important resource in facilitating team learning.  相似文献

This paper reconciles the inconsistent findings on the interactive effect of interactional justice and social comparison information on outcome evaluation. We distinguish two different effects of interactional justice and examine outcome uncertainty as a qualifying factor. Three hundred and fifty-seven undergraduates participated in a scenario experiment. It is found that, due to the functional quality effect, interactional justice significantly influences outcome evaluation, regardless of the social comparison information that is available, in situations of low outcome uncertainty. However, due to the fair process effect, interactional justice, as with procedural justice, interacts with social comparison information to influence outcome evaluation in situations of high outcome uncertainty. Implications for comparison referents and social comparison motives in social justice research are discussed.  相似文献

Perhaps the most challenging and creative aspect of clinical testing is the clinical inference process, the sequential steps the examiner takes in transforming the raw test data into a clinically relevant testing report. Unfortunately, this part of the testing process has received little attention in the testing literature. In this article, the specific steps in the inferential process are outlined. In addition, the ways in which theory enter into the inferential process are also discussed.  相似文献

Traditional Rorschach theory has consistently overlooked the linguistic aspect of the response process. Most conceptualizations focus on the perceptual and cognitive aspects of the process, never examining the subject's need to find a linguistic representation for the inner, perceptual process. This review examines the traditional formulations and suggests that new research from information-processing, neuropsychological, and dual-coding memory theory paradigms offer new possibilities for Rorschach research that would incorporate an appreciation of the unique cognitive demand of the test--the linking of percept with language.  相似文献

Abstract

We report five studies which compared two theories linking surprise to causal attribution. According to the attributional model, surprise is frequently caused by luck attributions, whereas according to the expectancy-disconfirmation model, surprise is caused by expectancy disconfirmation and stimulates causal thinking. Studies 1 to 3 focused on the question of whether surprise is caused by luck attributions or by unexpectedness. In Studies 1 and 2, subjects had to recall success or failure experiences characterised by a particular attribution (Study 1) or by low versus high surprisingness (Study 2), whereas in Study 3, unexpectedness and luck versus skill attributions were independently manipulated within a realistic setting. The main dependent variables were unexpectedness (Studies 1 and 2), degree of surprise (Studies 1 and 3), and causal attributions (Study 2). The results strongly suggest that surprise is caused by expectancy disconfirmation, whereas luck attributions are neither sufficient nor necessary for surprise. Studies 4 and 5 addressed the question of whether surprise stimulates attributional thinking, again using a remembered-incidents technique. The findings of the previous studies were replicated, and it was confirmed that surprising outcomes elicit more attributional search than unsurprising ones. Additional results from Study 5 suggest that causal thinking is also stimulated by outcomes that are both negative and important.  相似文献

The aim of this study was to highlight the underlying process responsible for the age-related deficit in recollection. Through two experiments using the Remember-Know-Guess procedure (Gardiner, J. M., & Richardson-Klavehn, A. [2000]. Remembering and knowing. In The Oxford handbook of memory (pp. 229–244). New York, NY: Oxford University Press) in recognition, we manipulated the opportunity to update bindings between target items and their encoding context, in young and older adults. In the first experiment we impaired the binding updating process during the encoding of items, while in the second we supported this process. The results indicated that the “Remember” responses in the younger group were specifically reduced by the impairment of the binding updating process (Exp. 1), suggesting that this ability is useful for them to encode a specific episode. Conversely, only the “Remember” responses in the older group were improved in accuracy by supporting the binding updating process (Exp. 2), suggesting that their weakness in this ability is the source of their failure to improve the accuracy of their memories. The overall results support the hypothesis that the age-related decline in episodic memory is partly due to a greater vulnerability to interference on bindings, impairing the ability to update content-context bindings as and when events occur.  相似文献

Children can express thoughts in gesture that they do not express in speech--they produce gesture-speech mismatches. Moreover, children who produce mismatches on a given task are particularly ready to learn that task. Gesture, then, is a tool that researchers can use to predict who will profit from instruction. But is gesture also useful to adults who must decide how to instruct a particular child? We asked 8 adults to instruct 38 third- and fourth-grade children individually in a math problem. We found that the adults offered more variable instruction to children who produced mismatches than to children who produced no mismatches--more different types of instructional strategies and more instructions that contained two different strategies, one in speech and the other in gesture. The children thus appeared to be shaping their own learning environments just by moving their hands. Gesture not only reflects a child's understanding but can play a role in eliciting input that could shape that understanding. As such, it may be part of the mechanism of cognitive change.  相似文献

ABSTRACT

In order to bridge the psychological and physical divide between different groups, researchers have harnessed the positive elements of the Internet to improve intergroup contact. One new and effective Internet strategy is Electronic- or E-contact. Unlike other contact approaches, E-contact is an experimental intergroup intervention that uniquely accommodates Allport’s contact theory and recategorisation processes, to create a structured, cooperative, synchronous and goal-directed online text interaction between members from different groups. E-contact has been found to successfully improve intergroup relations between Catholics and Protestants in Northern Ireland and Muslims and Catholics in Australia; and reduce bias against lesbian women and gay men, people with schizophrenia, Indigenous Australians, and transgender individuals. This paper discusses the unique engineering and advantages of E-contact interventions in comparison to existing contact strategies, identifies the theories that guide E-contact interventions, provides meta-analytic evidence of its effects, and discusses the strengths, limitations and future directions for E-contact research.  相似文献

The present studies examined the mediating role of self-regulatory mechanisms in the relationship between goal motivation and goal progress in the Self-Concordance Model. First, a systematic review, using meta-analytical path analysis, supported the mediating role of effort and action planning in the positive association between autonomous goal motivation and goal progress. Second, results from two additional empirical studies, using structural equation modeling, lent credence to the mediating role of coping in the relationship between goal motivation and goal progress of university students. Autonomous goal motivation was positively associated with task-oriented coping, which predicted greater goal progress during midterm exams (Study 1, N=702) and at the end of the semester in a different sample (Study 2, N=167). Controlled goal motivation was associated with greater disengagement-oriented coping (Study 1 and Study 2) and lesser use of task-oriented coping (Study 2), which reduced goal progress. These results held up after controlling for perceived stress (Study 2). Our findings highlight the importance of coping in the "inception-to-attainment" goal process because autonomous goal motivation indirectly rather than directly predicts goal progress of university students through their usage of task-oriented coping.  相似文献

The purpose of this study was to investigate the relationship between goal specificity and task performance, with specificity operationalized as a continuous quantitative variable reflecting the range of performance levels individuals chose as their personal goals. It was hypothesized that, controlling for goal difficulty, specific personal goals would be associated with higher levels of task performance. It was also hypothesized that task strategy would mediate the relationship between goal specificity and performance and that specific goals would be associated with smaller goal-performance discrepancies. The results from a sample of 162 college students working on an eye-hand coordination task supported the hypothesis concerning goal-performance discrepancies. They hypotheses regarding task strategy and the relationship between goal specificity and performance were supported only on the second of two trials.  相似文献
