The effect of personality variables in the prediction of the execution of different prospective memory tasks in the laboratory

The study of prospective memory (ProM), the remembering of the delayed execution of intentions, has been growing in recent years, and we know quite a bit about the cognitive variables that affect it. But the performance of a task depends on personality variables as well as on cognitive ones, and the role of personality variables in ProM has only been partially studied, the results being less conclusive. We sought to address two main objectives: (1) to quantify the joint influence of cognitive and personality variables on three ProM tasks in the laboratory (two based on events and the other on time), and (2) to identify the personality profiles of those who perform well in these three ProM tasks as opposed to those who do not. The cognitive and personality variables were evaluated with two sessions of 157 participants. The 16 PF-5 was applied (Cattell, Cattell & Cattell, 1993) and other cognitive variables were measured. With the data obtained, we ran several regression analyses to determine how some cognitive variables (sustained attention, verbal fluency, interference, retrospective memory, selective attention) and personality factors (tested using the 16 PF-5) can help to explain the variance in the performance of prospective memory tasks. Our results show that the contribution of personality predictor variables is moderate and smaller than that of the cognitive variables for predicting the execution of ProM tasks in the laboratory. Furthermore the intervention of the personality variables differs depending on the ProM tasks used. Global self-control and rule-consciousness were the personality variables that contributed the most in the prediction of the scores in the ProM tasks that were used.     

A Work-Life Identity Model of Well-Being: Towards a Research Agenda Linking Quality-of-Work-Life (QWL) Programs with Quality of Life (QOL)

QWL is conceptualized in terms of the interface between employee role identities and work resources. QWL programs serve to enhance QOL by (1) providing appropriate work resources to meet the expectations of employee role identities, (2) reducing role conflict in work and non-work life, (3) enhancing multiple role identities, (4) reducing role demands, (5) reducing stress related to work and non-work role identities, and (6) increasing the value of the role identity. We describe a variety of QWL programs related to work life (decentralized organization structures, teamwork, parallel structures, ethical corporate mission and culture, the organization work schedule, etc.) and non-work life (work at home, flextime, compressed work week, part-time work arrangements, job sharing, etc.) and show how they serve to enhance QOL using the language of work-life identity. Doing so helps develop a research agenda based on the work-life identify model.

The work-related flow inventory: Construction and initial validation of the WOLF

The WOrk-reLated Flow inventory (WOLF) measures flow at work, defined as a short-term peak experience characterized by absorption, work enjoyment, and intrinsic work motivation. Results of Study 1 among 7 samples of employees (total N = 1346) from different occupational groups offer support for the factorial validity and reliability of the WOLF. Study 2 examined the validity of the WOLF in more detail among some of the samples. Positive correlations between a general flow index and the three flow dimensions confirm the convergent validity of the WOLF. In addition, the findings of Study 2 provide evidence for the construct and predictive validity of the WOLF using five job characteristics as predictors of flow, and other-ratings of performance as outcomes.     

Interactive effects of work group and organizational identification on job satisfaction and extra-role behavior

Past research has focused on the differential relationships of organizational and work group identification with attitudes and behavior. However, no systematic effort has been undertaken yet to explore interactive effects between these foci of identification. We predicted that in cases of positive overlap of identifications (i.e. high work group and organizational identification) identifications are more strongly associated with employee job satisfaction and extra-role behavior than when only one of the identifications is high—that is, the one identification augments the influence of the other. These hypotheses were tested and supported with data from two samples of bank employees (N = 358) and travel agency employees (N = 308).     

When earning is beneficial for learning: The relation of employment and leisure activities to academic outcomes

The present study investigates the joint effect of the quantity and quality of out-of-school activities (i.e., employment and leisure) on academic outcomes (i.e., well-being, study attitude, and academic performance) among 230 undergraduates. A series of hierarchical regression analyses show that spending too much time in both employment and leisure activities has negative relations with undergraduates’ academic outcomes. Work-study interference fully mediated the effect of time engagement in student employment on students’ reported well-being. These findings support a conflict perspective on multiple role engagement. However, results also show positive effects of activities depending on job demand and autonomy and level of autonomous motivation to engage in these activities. We conclude that out-of-school activities can be beneficial for students’ academic outcomes and preparation for the labor market when perceived as relevant for their academic study and performed in a balanced, autonomous way.     

Coordinating cognition: the costs and benefits of shared gaze during collaborative search

Collaboration has its benefits, but coordination has its costs. We explored the potential for remotely located pairs of people to collaborate during visual search, using shared gaze and speech. Pairs of searchers wearing eyetrackers jointly performed an O-in-Qs search task alone, or in one of three collaboration conditions: shared gaze (with one searcher seeing a gaze-cursor indicating where the other was looking, and vice versa), shared-voice (by speaking to each other), and shared-gaze-plus-voice (by using both gaze-cursors and speech). Although collaborating pairs performed better than solitary searchers, search in the shared gaze condition was best of all: twice as fast and efficient as solitary search. People can successfully communicate and coordinate their searching labor using shared gaze alone. Strikingly, shared gaze search was even faster than shared-gaze-plus-voice search; speaking incurred substantial coordination costs. We conclude that shared gaze affords a highly efficient method of coordinating parallel activity in a time-critical spatial task.     

Role of endpoints and closures in feature search1

Abstract: The present study intended to examine the role of endpoints and of closures, the two most frequently referred to features, in a feature‐search paradigm. Two experiments were conducted with a rigorous stimulus control using random lined figures of different levels of complexity. The experiments gave almost identical results: there was no search asymmetry between the two features, smaller latencies were obtained in the presence of a feature as a target rather than in its absence, and the latencies were smaller for the displays having a background consisting of closures rather than for those having a background of endpoints. The results were more comprehensively explained by the high contrast between an endpoint as a target and closures as a background, rather than the conspicuity of an endpoint as a target. The possibility for closures to group into a homogeneous ground was discussed.     

Frames of reference for the light-from-above prior in visual search and shape judgements

Faced with highly complex and ambiguous visual input, human observers must rely on prior knowledge and assumptions to efficiently determine the structure of their surroundings. One of these assumptions is the 'light-from-above' prior. In the absence of explicit light-source information, the visual system assumes that the light-source is roughly overhead. A simple, low-cost strategy would place this 'light-from-above' prior in a retinal frame of reference. A more complex, but optimal strategy would be to assume that the light-source is gravitationally up, and compensate for observer orientation. Evidence to support one or other strategy from psychophysics and neurophysiology has been mixed. This paper pits the gravitational and retinal frames against each other in two different visual tasks that relate to the light-from-above prior. In the first task, observers had to report the presence or absence of a target where distractors and target were defined purely by shading. In the second task, observers made explicit shape judgements of similar stimuli. The orientation of the stimuli varied across trials and the observer's head was fixed at 0, +/-45 or +/-60 degrees . In both tasks the retinal frame of reference dominated. Visual search behaviour with shape-from-shading stimuli (SFS) was modulated purely by stimulus orientation relative to the retina. However, the gravitational frame of reference had a significant effect on shape judgements, with a 30% correction for observer orientation. In other words, shading information is processed quite differently depending on the demands of the current task. When a 'quick and dirty' representation is required to drive fast, efficient search, that is what the visual system provides. In contrast, when the task is to explicitly estimate shape, extra processing to compensate for head orientation precedes the perceptual judgment. These results are consistent with current neurophysiological data on SFS if we re-frame compensation for observer orientation as a cue-combination problem.     

《公羊传》“以义解经”的意图探析

一般史家眼中的《春秋》是一部简单的历史著作,可公羊家视阈中的《春秋》却是蕴涵“微言大义”的经学宝典。《公羊传》“以义解经”,以为“义”之所在可从作者意图、文本意图和读者意图来窥探。一方面《公羊传》有还原倾向,旨在探求作者意图和文本意图,表现为尊圣宗经原道;另一方面又有生成倾向,多“非常异义可怪之论”,旨在阐述自己的政治、历史、道德理想。
