Visual attribute modulates the time course of iconic memory decay

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.     

Enhancing Social Entrepreneurial Intentions through Entrepreneurial Creativity: A Comparative Study Between Taiwan and Hong Kong

Attention toward social entrepreneurship has increased worldwide, particularly within younger generations. Based on the identified model of social entrepreneurial intentions, this study proposed a multiple mediation framework to examine the mediating role of entrepreneurial creativity for university students. It also compared the differences between Taiwanese (N = 311) and Hong Kong students (N = 311). Through a survey using both online and offline channels, the results of Study 1 confirmed the factor structures of the 3 scales, involving 5 antecedents of social entrepreneurial intention (i.e., empathy, moral obligation, self-efficacy, perceived social support, and prior experience with social problems), 2 factors of entrepreneurial creativity (i.e., originality and usefulness), and 2 factors of social entrepreneurial intention (i.e. conviction and preparation). The results of Study 2 supported the proposed multiple mediation model across regions. Prior experience with social problems, perceived social support, and originality were identified as the 3 most influential factors affecting the social entrepreneurial intentions of university students. The major differences between Taiwan and Hong Kong involved prior experience, empathy, self-efficacy, perceived social support, and usefulness.     

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.     

Benefits of team participative decision making and its potential to affect individual creativity

How does team participative decision‐making affect individual creative performance? Building on team climate theory (Anderson & West, 1998; West 1990, 2002; West & Sacramento, 2012), this study investigates the indirect effect of team participative decision making on employee creativity through individual perception of cognition team diversity and psychological safety. Results from 256 supervisor–subordinate dyads in 45 teams show that team participative decision making is positively associated with cognitive team diversity and psychological safety. For the mediating effects, team participative decision‐making climate is positively indirectly related to creative performance via psychological safety but not via cognitive team diversity. Theoretical and practical implications are discussed.     

Vocational Personality Traits in Counselor Education and School Psychology Students

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.     

Electrophysiological difference between the representations of causal judgment and associative judgment in semantic memory

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.     

Burger or yogurt? Indulgent consumption in impression management contexts

We conducted three studies to investigate indulgent choice in settings with and without impression management by public–private manipulation with evaluation. Study 1 showed that the participants were less indulgent under public scrutiny due to the employment of impression management. Study 2 focused on the impression management context to test the moderate effect of self‐consciousness in two impression managed contexts. Study 3 focused on context without impression management to test the moderate effects of self‐awareness on choices. We found that depending on differences in primed personality, individuals tended to make choices other than those they favoured privately when anticipating that others might form impressions of them based on the decisions made. The findings of all three studies support our basic prediction that people are less indulgent under impression management and suggest that people tend to manage their impression by eating healthier (less indulgently) in public.     

A general proof of consistency of heuristic classification for cognitive diagnosis models

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.
