It has often been suggested that Gestalt-like visual grouping processes may operate preattentively, but Mack and Rock (1998) suggested that no visual grouping takes place under “inattention.” We introduced a new method to assess this. While participants performed a demanding change-detection task on a small matrix at fixation, task-irrelevant background elements were arranged by color similarity into columns, rows, or pseudorandomly. Independent of any change in the target matrix, background grouping could also change or remain the same on each trial. This influenced accuracy of change judgments for the central task, even though background grouping or its change usually could not be explicitly reported when probed with surprise questions as in Mack and Rock. This suggests that visual grouping may arise implicitly under inattention and provides a new method for testing the boundaries of this processing. Here we extended the initial result to changes in background grouping remote from the target and to those occurring across an intervening saccade. 相似文献

In this essay I articulate and defend a thesis about the nature of morality called “the embodiment thesis”. The embodiment
thesis states that moral values underdetermine the obligations and entitlements of individual persons, and that actual social
institutions must embody morality by specifying these moral relations. I begin by presenting two thought experiments that
elucidate and motivate the embodiment thesis. I then proceed by distinguishing the embodiment thesis from a Rawlsian doctrine
about the nature of justice, from the doctrine of moral relativism, and from solutions to the coordination problem of rational
choice theory. 相似文献

Throughout evolutionary history, intergroup competition has been an influential part of social life. Although the topic has received substantial empirical attention among social psychologists, the majority of that work has focused on how ingroup and outgroup members regard one another. Only recently have researchers begun examining how intergroup rivalry changes that way that ingroup members perceive and relate to one another. New findings suggest that a variety of within‐group processes are influenced by the presence of a rival outgroup. In general, altruistic cooperation and prosocial motives increase among ingroup members when their group competes against another. The relationship between leaders and followers also shifts in response to intergroup rivalry: rather than wielding their power for selfish purposes, leaders prioritize the needs of their group. On the flip side, followers’ choice of leader changes, preferring males during times of intergroup competition but females in the absence of competition. Given the substantial impact of intergroup competition on ingroup processes, future research should continue to deepen the field’s knowledge of this topic. Additionally, the scope of research should be broadened to capture the effect of intergroup competition on ingroup dynamics, such as performance and group outcomes. 相似文献

Gronlund ( 2005 ) proposed that one factor leading to a sequential line-up advantage could be the greater likelihood of recollecting distinctive information about a perpetrator when using a sequential line-up. Since then questions have been raised about the robustness of the sequential advantage and the possible moderating role of line-up fairness and suspect position. We manipulated these factors as well as suspect/target distinctiveness in two experiments. A sequential advantage occurred only after encoding a distinctive target, both for biased line-ups (Experiment 1) and fair line-ups (Experiment 2). Remember-Know results were consistent with the greater use of a recall-to-reject strategy in target-absent sequential line-ups. This provided support for the first process-based explanation of the sequential line-up advantage. No consistent position effects were found, but this might be due to the line-up recognition paradigm used, in which each participant viewed a line-up for each of several targets. Theory-based explorations of eyewitness identification are necessary to continue to delineate the underpinnings of the sequential line-up advantage. 相似文献

Relations among conceptual knowledge, procedural knowledge, and procedural flexibility in two samples differing in prior knowledge 总被引:1,自引:0,他引:1
Competence in many domains rests on children developing conceptual and procedural knowledge, as well as procedural flexibility. However, research on the developmental relations between these different types of knowledge has yielded unclear results, in part because little attention has been paid to the validity of the measures or to the effects of prior knowledge on the relations. To overcome these problems, we modeled the three constructs in the domain of equation solving as latent factors and tested (a) whether the predictive relations between conceptual and procedural knowledge were bidirectional, (b) whether these interrelations were moderated by prior knowledge, and (c) how both constructs contributed to procedural flexibility. We analyzed data from 2 measurement points each from two samples (Ns = 228 and 304) of middle school students who differed in prior knowledge. Conceptual and procedural knowledge had stable bidirectional relations that were not moderated by prior knowledge. Both kinds of knowledge contributed independently to procedural flexibility. The results demonstrate how changes in complex knowledge structures contribute to competence development. 相似文献

This study examined organizational levers that impact work-family experiences, participant health, and subsequent turnover. Using a sample of 179 women returning to full-time work 4 months after childbirth, we examined the associations of 3 job resources (job security, skill discretion, and schedule control) with work-to-family enrichment and the associations of 2 job demands (psychological requirements and nonstandard work schedules) with work-to-family conflict. Further, we considered subsequent impact of work-to-family conflict and enrichment on women's health (physical and mental health) 8 months after women returned to work and the impact of health on voluntary turnover 12 months after women returned to work. Having a nonstandard work schedule was directly and positively related to conflict, whereas schedule control buffered the effect of psychological requirements on conflict. Skill discretion and job security, both job resources, directly and positively related to enrichment. Work-to-family conflict was negatively related to both physical and mental health, but work-to-family enrichment positively predicted only physical health. Physical health and mental health both negatively influenced turnover. We discuss implications and opportunities for future research. 相似文献

As faces become familiar, recognition becomes easier but the style of processing also changes. Here, twenty-one typically developing (TD) children and twenty-one children with autism spectrum disorder (ASD) were familiarised with 6 identities over 3 days. Next, they completed a 4-alternative forced-choice matching test in which targets were the 6 familiarised faces and 6 unfamiliar faces. The TD group showed a significant advantage for familiarised faces when matching whole faces and both internal and external facial regions. The ASD group showed similar familiarisation effects for whole and external faces, but not for internal regions. The ASD group was also impaired at matching eyes and mouths of familiarised faces. Results suggest the process of acquiring familiarity with faces differs from ASD and TD children. 相似文献
