Studies on iconic memory demonstrate that rich information from a visual scene quickly becomes unavailable with the passage of time. The decay rate of iconic memory refers to the dynamics of memory availability. The present study investigated the iconic memory decay of different stimulus attributes that comprised an object. Specifically, in Experiment 1, participants were presented with eight coloured numbers (e.g., red 4) and required to remember only one attribute, either colour or number, over different blocks of trials. The participants then reported the cued attribute in which the cue Stimulus Onset Asynchrony (SOA) from the memory array onset was varied (0, 100, 200, 300, 500, and 1000?ms). We found that numerical information became unavailable more quickly than colour information, despite the fact that the memory accuracies at 0 and 1000?ms SOAs were comparable between the two attributes. In Experiment 2, we replicated the finding that a numerical representation was lost more quickly than a colour representation when visual masks followed the target stimulus. These results suggest that the various visual attributes comprising an object are lost over time at different rates in iconic memory. We discuss this finding in relation to how perceptual representation is transferred to the capacity-limited visual working memory. 相似文献

Are Decisions Made by Group Representatives More Risk Averse? The Effect of Sense of Responsibility

We tested the hypothesis that a sense of responsibility drives group representatives' decisions to be more risk averse compared with decisions made by individuals. The hypothesis was supported when the monetary considerations (i.e., payoff inequality and the magnitude effect) were controlled for in the potential gain domain as well as in the potential loss domain. Evidence showed that this is because the group representatives were concerned about how they would view themselves (e.g., guilt and self‐blame) and also how they would be viewed by others (i.e., to avoid being blamed and looked down upon by others). This study provided new insights into understanding group representatives' decision making under risk. Copyright © 2017 John Wiley & Sons, Ltd. 相似文献

We assessed the vocational personality of 104 graduate students in school counseling, mental health counseling, and school psychology programs using Holland's ( 1997 ) theory of personality and career choice. The correlational findings confirmed the importance of vocational personality traits in relation to the academic performance of graduate students. Among the Self‐Directed Search–Revised vocational personality types, the Investigative type emerged as a consistent predictor of performance on all sections of the Graduate Record Examination. The participants from 3 graduate programs predominantly identified Social as their primary vocational personality type, with variability in the secondary and tertiary code positions. The student group with the highest degree of congruence, defined as the degree of fit between one's personality and the environment, had the highest graduate grade point average, indicating the relationship between the degree of congruence and achievement. Theoretical and practical implications of the findings are discussed. 相似文献

Causally related concepts like “virus” and “epidemic” and general associatively related concepts like “ring” and “emerald” are represented and accessed separately. The Evoked Response Potential (ERP) procedure was used to examine the representations of causal judgment and associative judgment in semantic memory. Participants were required to remember a task cue (causal or associative) presented at the beginning of each trial, and assess whether the relationship between subsequently presented words matched the initial task cue. The ERP data showed that an N400 effect (250–450 ms) was more negative for unrelated words than for all related words. Furthermore, the N400 effect elicited by causal relations was more positive than for associative relations in causal cue condition, whereas no significant difference was found in the associative cue condition. The centrally distributed late ERP component (650–750 ms) elicited by the causal cue condition was more positive than for the associative cue condition. These results suggested that the processing of causal judgment and associative judgment in semantic memory recruited different degrees of attentional and executive resources. 相似文献

The Asymptotic Classification Theory of Cognitive Diagnosis (Chiu et al., 2009, Psychometrika, 74, 633–665) determined the conditions that cognitive diagnosis models must satisfy so that the correct assignment of examinees to proficiency classes is guaranteed when non‐parametric classification methods are used. These conditions have only been proven for the Deterministic Input Noisy Output AND gate model. For other cognitive diagnosis models, no theoretical legitimization exists for using non‐parametric classification techniques for assigning examinees to proficiency classes. The specific statistical properties of different cognitive diagnosis models require tailored proofs of the conditions of the Asymptotic Classification Theory of Cognitive Diagnosis for each individual model – a tedious undertaking in light of the numerous models presented in the literature. In this paper a different way is presented to address this task. The unified mathematical framework of general cognitive diagnosis models is used as a theoretical basis for a general proof that under mild regularity conditions any cognitive diagnosis model is covered by the Asymptotic Classification Theory of Cognitive Diagnosis. 相似文献

In this study, we examined the hypothesis that semantic judgment tasks share overlapping processes if they require processing on common dimensions but not if they require processing on orthogonal dimensions in semantic space (Osgood, Suci, & Tannenbaum, 1957). We tested the hypothesis with the implicit association test (IATl Greenwald, McGhee, & Schwartz, 1998) in three experiments. Consistent with the hypothesis, IAT effects (costs in reaction time because of incompatible response mapping between associated judgment tasks) occurred consistently when judgment tasks tapped into common semantic dimensions, whereas no IAT effect appeared when judgment tasks entailed processing on orthogonal semantic dimensions. 相似文献

In an experiment with 80 participants in China, protagonists with opposing views in organizations that valued collectivism, compared to individualism, were found to develop cooperative goals, were confident that they could work, sought to understand, and demonstrated that they understood the opposing arguments, accepted these arguments as reasonable, and combined positions to create an integrated decision. The inductions comparing participants who valued harmony as a goal or a technique in which they pretended to agree were only partially effective and did not yield significant differences on conflict dynamics and outcomes. Findings challenge traditional theorizing that collectivistic values lead to conflict avoidance, and support recent arguments that strong, cooperative relationships promote the productive discussion of opposing views in decision making. 相似文献

This essay explores the history of studies in analytical philosophy in China since the beginning of the last century, by dividing
into three phases. It shows that, in these phases, analytic philosophy was always at a disadvantage in confronting serious
challenges coming from both Chinese traditional philosophy and modern philosophical trends. The authors argue that Chinese
philosophers have both done preliminary studies and offered their own analyses of various problems as well as some new applications
of analytic philosophy especially in the latest period. Meanwhile, Chinese traditional philosophy was always trying to adjust
its cultural mentality in the struggle with analytic philosophy, and accommodated in its own way the rationalistic spirit
and scientific method represented in analytic philosophy. 相似文献
