We investigated the role of attention in pairing superimposed visual features. When moving dots alternate in color and in motion direction, reports of the perceived color and motion reveal an asynchrony: the most accurate reports occur when the motion change precedes the associated color change by approximately 100ms [Moutoussis, K., & Zeki, S. (1997). A direct demonstration of perceptual asynchrony in vision. Proceedings of the Royal Society of London B, 264, 393-399]. This feature binding asynchrony was probed by manipulating endogenous and exogenous attention. First, endogenous attention was manipulated by changing which feature dimension observers were instructed to attend to first. This yielded little effect on the asynchrony. Second, exogenous attention was manipulated by briefly presenting a ring around the target, cueing the report of the color and motion seen within the ring. This reduced or eliminated the apparent latency difference between color and motion. Accuracy was best predicted by timing of each feature relative to the cue rather than the timing of the two features relative to each other, suggesting independent attentional access to the two features with an exogenous attention cue. The timing of attentional cueing affected feature pairing reports as much as the timing of the features themselves.  相似文献

This study examined how children's insecure internal representations of interparental and parent-child relationships served as explanatory mechanisms in multiple pathways linking interparental conflict and parent emotional unavailability with the emotional and classroom engagement difficulties the children had in their adjustment to school. With their parents, 229 kindergarten children (127 girls and 102 boys, mean age = 6.0 years, SD = .50, at Wave 1) participated in this multimethod, 3-year longitudinal investigation. Findings revealed that children's insecure representations of the interparental relationship were a significant intervening mechanism in associations between observational ratings of interparental conflict and child and teacher reports on children's emotional and classroom difficulties in school over a 2-year period. Moreover, increased parental emotional unavailability accompanying high levels of interparental conflict was associated with children's insecure representations of the parent-child relationship and children's difficulties in classroom engagement at school entry. The findings highlight the importance of understanding the intrinsic processes that contribute to difficulties with stage-salient tasks for children who are experiencing interparental discord.  相似文献

Pack behavior     
We analyze a sequential decision model, where every decision maker has her own preferences over actions. Some actions have positive Externalities if a large enough population has previously chosen them, and those Externalities may lead a decision-maker to ignore her own preferred actions to benefit from those Externalities. We give a fairly general sufficient condition such that, on almost every equilibrium path, every decision maker eventually prefers to benefit from group Externalities. We show that this situation, called pack behavior, is observationally equivalent to a herd behavior, but it is triggered by positive Externalities generated by group decision, instead of standard belief-based decisions. We also show that this notion is not ex-ante Pareto-efficient in general.  相似文献

The objective was to examine the social conditions under which subjects could attribute trait adjectives to an unknown person, the paradigm of impression-formation at zero acquaintance. The situation on which the subject had to base his judgement was a 90-sec. film clip with sound of an individual reading a weather forecast. Analysis showed traits were attributed more quickly and consistently when instructions stipulated subject should evaluate the social utility of an individual (evaluator-recruiter type instructions) rather than describe personality (psychologist-type instructions). Traits were attributed more rapidly, with more consistency and greater certainty. Interpretation of results, which generally corroborate other research, is that the judgement of another person based on a first impression is an evaluation of the social utility of that person.  相似文献

The potential for applicant response distortion on personality measures remains a major concern in high‐stakes testing situations. Many approaches to understanding response distortion are too transparent (e.g., instructed faking studies) – or are too subtle (e.g., correlations with social desirability measures as indices of faking). Recent research reveals more promising approaches in two methods: using forced‐choice (FC) personality test items and warning against faking. The present study examined effects of these two methods on criterion‐related validity and test‐taker reactions. Results supported incremental validity for an FC and Likert‐scale measure in warning and no‐warning conditions, above and beyond cognitive ability. No clear differences emerged between the FC vs Likert measures or warning vs no‐warning conditions in terms of validity. However, some evidence suggested that FC measures and warnings may produce negative test‐taker reactions. We conclude with implications for implementation in selection settings.  相似文献

This study empirically synthesizes and evaluates studies that have examined the relation between vocationally relevant domains of self-efficacy and interests. We conducted a meta-analytic review of 60 empirical independent samples (N=39,154) in which relations between self-efficacy and interests had been examined. Fifty-three of these samples (N=37,829) included parallel measures of the constructs. Relations between parallel measures of Holland’s RIASEC themes, the specific dimensions of art, math, science and math/science combined, and traditionally female and male occupations are also presented. Results demonstrated that self-efficacy and interests are independent constructs that correlate moderately. Differences by sex, measure, and age group are noted. Future directions for research regarding links between self-efficacy and interests are discussed.  相似文献

This study provides a preliminary analysis of how the techniques of fluency training can be combined with systematic concept instruction to improve the learning of complex verbal concepts. Fluency techniques, which require the learner to respond accurately at high rates, have typically focused on definition learning when teaching concepts. Instructional psychologists, however, recommend multiple exemplar training for conceptual instruction. To examine this issue, 41 undergraduate students completed a computer-based instructional module on logical fallacies. Participants were assigned to one of four groups, with the modules for each group differing only in the type of practice provided—either fluency or practice with either examples or definitions. Examination of posttest scores revealed significantly higher scores for participants in the examples groups than those in the definitions groups, but low experimental power prevented a clear conclusion to be drawn about differences between the fluency and practice groups. Implications of results and several methodological issues relevant to this area of research are discussed.  相似文献

This study aimed at examining the ways in which different athletes may combine the use of several coping strategies and at testing whether perceived goal attainment, affective states, and experience of control would differ across distinctive profiles of coping. A sample of 151 French-Canadian athletes out of 200 who were approached by a research assistant completed l’Inventaire des Strat gies de Coping en Comp tition Sportive (Gaudreau & Blondin, 2002a), the PANAS ( Watson, Clark, & Tellegen, 1988), and a series of items measuring experience of control and perceived goal attainment. Results of a cluster analysis indicated that athletes could be classified in four groups according to their in-competition use of coping strategies. After controlling for athletes’ self-referenced goal attainment, their experience of control, positive affective state, and anger-dejection state differed significantly (p<0.008) across the four profiles of coping. Athletes who have used high level of task-oriented coping in combination with low level of disengagement-oriented coping reported better goal and psychological adjustment than athletes who have used high level of disengagement-oriented coping in combination with low level of task-oriented coping. Overall, these findings suggested that research should move from coping strategies to coping profiles in order to provide a deeper understanding of how different individuals cope with stress.  相似文献

The stem cell controversy raises a fundamental question for humankind. Does science have a right to pursue knowledge whatever the cost? Our Enlightenment culture says yes. However, human history and literature are sending warning signals. Ethical issues impact the “knowledge for its own sake” imperative, and must be addressed.  相似文献

This study assessed the effects of various predictor variables on dimensions of functioning within alcoholic families. Participants were 173 college student volunteers from alcoholic families who completed a measure of family functioning, demographic questions, and questions related to experiences in their families of origin. Child abuse, spousal violence, parental divorce, length of time living with an alcoholic parent, parental marital status, and parental availability and predictability significantly affected family functioning, whereas frequency of parental drinking did not. Results suggest that quality of parental interactions with children is more important for functioning in alcoholic families than frequency of parental drinking.  相似文献
