The collaborative encoding deficit is attenuated with specific warnings

Individuals learning together do so less effectively than individuals learning alone, an effect known as the collaborative encoding deficit. In the present studies we examined whether providing participants with a warning about the collaborative encoding deficit would increase their encoding task performance, and reduce subsequent memory deficits. Across two experiments, specific warnings were beneficial for memory. Collaborating participants who were told about the collaborative encoding deficit, and who received suggestions for how to complete the encoding task, had superior memory than participants who received no warning. This benefit was not due to qualitative changes in encoding task performance, was unrelated to the type of collaboration utilised, was absent when a more general warning was utilised, and was unrelated to self-reported task motivation. Rather, specific warnings appear to protect against the collaborative encoding deficit by increasing time spent on, and attention directed to, the encoding task.     

Impact of Corporate Social Responsibility Attributions on Employees’ Creative Performance: The Mediating Role of Psychological Safety

This study contributes to the growing literature on individual-level outcomes of corporate social responsibility (CSR). Employing a sample of 339 subordinate–supervisor dyads, we explored the differential impact of CSR attributions on employees’ creative performance in the telecom industry. We also introduced and tested the role of psychological safety as a mediator underlying this relationship. The results indicate that although intrinsic CSR attributions are not directly related to creative performance, extrinsic CSR attributions have a significant negative effect on creative performance. We also found that psychological safety mediates the positive relationship between intrinsic CSR and creative performance and the negative relationship between extrinsic CSR and creative performance. Directions for future research and implications for practice are discussed.     

Impact of Ethical Leadership on Organizational Safety Performance: The Mediating Role of Safety Culture and Safety Consciousness

We examined a largely ignored but imperative dimension of safety literature by testing the impact of ethical leadership style on organizational safety performance. We also tested dual mediating paths of safety culture and safety consciousness in the relationship between ethical leadership style and organizational safety consciousness. Data (N = 230) were collected from a large public sector telecom company in Pakistan. Confirmatory factor analysis was used to assess the reliability and validity of the study scales and model fit. Preacher and Hayes’s (2008) macro of mediation was employed to test the direct and indirect paths proposed in the study. The findings suggest that ethical leadership has a positive impact on organizational safety performance. Partial mediating roles of safety culture and safety consciousness were also found between the dependent and independent variables. Theoretical and practical implications are discussed.     

Anxiety,coping and academic performance

Anxiety is a frequent response to stressful evaluation situations and may be correlated with the performance being evaluated. The present study investigated individual differences in social evaluation trait anxiety and coping dimensions as predictors of state anxiety and performance on a university examination. Separate multiple regressions were computed for coping assessed as a style, an individual difference measure, and as situational specific responses. Emotion-oriented coping predicted state anxiety in the evaluation situation. Social evaluation trait anxiety and task-oriented and emotionoriented coping responses predicted exam performance. The regression models predicted approximately a quarter of the variance in course grades. When coping was measured as a response, task-oriented coping response was a significant predictor of course grade. When coping was measured as a style or individual difference, avoidance-oriented coping style predicted aggregated course grade. It was suggested that different coping dimensions predict different outcomes and that coping be assessed over time to better understand its relation to performance.     

Individuals lower in working memory capacity are particularly vulnerable to anxiety's disruptive effect on performance

Abstract

Anxiety has a disruptive effect on performance in a number of domains. The purpose of this study was to determine whether individual differences in working memory (WM) capacity are related to an individual's susceptibility to anxiety's detrimental effect on performance. Fifty undergraduate students (28 females) were administered the State-Trait Anxiety Inventory (STAI) (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) to measure trait anxiety and the automated operation span task to measure WM capacity (Unsworth, Heitz, Schrock, & Engle, 2005). Then, they performed a highly demanding dual-task that consisted of a primary short-term memory task and a secondary tone-discrimination task that served as a measure of spare capacity. Anxiety and WM capacity interacted to affect performance on the auditory task so that those low in WM capacity were particularly vulnerable to anxiety's disruptive effect, whereas those high in WM capacity were buffered against anxiety's effect. These findings suggest that WM capacity may be an important factor in determining which individuals underperform on anxiety-provoking tests such as scholastic achievement tests.     

Temporal binding during apparent movement of the human body

Alternating between static images of human bodies with an appropriate interstimulus interval (ISI) produces apparent biological motion. Here we investigate links between apparent biological motion and time perception. We presented two pictures of the initial and final positions of a human movement separated by six different ISIs. The shortest movement path between two positions was always biomechanically impossible. Participants performed two tasks: In an explicit task, participants judged whether they saw the longer, feasible movement path between the two postures, or the shorter, biomechanically impossible path. In an implicit task, participants judged the duration of a white square surrounding the picture sequence. At longer ISIs participants were more likely to see a longer, feasible movement path (explicit task) and underestimated the duration of body picture pairs, compared to trials displaying degraded body pictures (implicit task). We argue that perceiving apparent biological motion involves temporal binding of two static pictures into a continuous movement. Such temporal binding may be mediated by a top-down mechanism that produces a percept of biological motion in the absence of any retinal motion.     

A new form of human spatial attention: Automated symbolic orienting

The control of human attention is typically conceptualized either in terms of exogenous automatic processes that are driven by external sensory stimulation or endogenous strategic processes that are driven by internal expectancies about events in the environment. However, this classic dichotomy has struggled to explain a wealth of new data demonstrating that behaviourally and biologically relevant visual stimuli, like arrow and eye direction, elicit shifts of spatial attention that on the one hand, appear exogenous, and on the other hand, endogenous. To address this issue, we used a double-cueing task that combined arrows with classic cues known to invoke either exogenous or endogenous orienting. Our data suggest that behaviourally relevant directional cues, like arrows, engage a new form of cortically mediated orienting—automated symbolic orienting—that operates independent of, and in parallel with, the two classic forms of exogenous and endogenous spatial attention.     

Specifying the human body configuration

Three experiments investigated the specific spatial relations that define the human body configuration. In Experiment 1, participants searched for scrambled bodies amongst normal distractors. In Experiments 2 and 3 participants were asked to identify whether single body images (upright or inverted) were scrambled or normal. Scrambled bodies had head or limbs displaced to either symmetrical or asymmetrical positions. Experiment 1 showed that asymmetrical violations are recognized faster than symmetrical violations. All three experiments revealed that when the number of structural violations is held constant, head violations are recognized faster than limb violations. Experiment 3 also showed a greater inversion effect for scrambled bodies that maintained head on top and vertical symmetry, providing evidence that these are key spatial relations in the human body configuration. Overall, the results supported our hypothesis that the human body configuration is defined primarily by a head at the apex of a vertically symmetrical body.     

Cognition- and Affect-Based Trust and Feedback-Seeking Behavior: The Roles of Value,Cost, and Goal Orientations

We examined how subordinates’ cognition- and affect-based trust in supervisors influences their feedback-seeking behavior (FSB) by considering the different cost/value perception of FSB and goal orientation (i.e., learning and performance goal orientations). Using data from 194 supervisor-subordinate dyads in South Korea, we conducted multiple regression analyses to test our hypotheses. The results showed that, whereas subordinates’ cognition-based trust in supervisors positively influenced their FSB through increasing the perceived value of feedback received from supervisors, their affect-based trust in supervisors positively influenced their FSB through decreasing the perceived value of FSB. Additionally, we found that, when subordinates had high levels of learning goal orientation, the increasing influence of cognition-based trust on the value of feedback was stronger; in contrast, when subordinates had low levels of performance goal orientation, the decreasing influence of affect-based trust on the cost of FSB was stronger. The theoretical and practical implications, limitations, and suggestions for future research were discussed.     

Cultural Values and Performance Appraisal: Assessing the Effects of Rater Self-Construal on Performance Ratings

Much of the prior research investigating the influence of cultural values on performance ratings has focused either on conducting cross-national comparisons among raters or using cultural level individualism/collectivism scales to measure the effects of cultural values on performance ratings. Recent research has shown that there is considerable within country variation in cultural values, i.e. people in one country can be more individualistic or collectivistic in nature. Taking the latter perspective, the present study used Markus and Kitayama's (1991) conceptualization of independent and interdependent self-construals as measures of individual variations in cultural values to investigate within culture variations in performance ratings. Results suggest that rater self-construal has a significant influence on overall performance evaluations; specifically, raters with a highly interdependent self-construal tend to show a preference for interdependent ratees, whereas raters high on independent self-construal do not show a preference for specific type of ratees when making overall performance evaluations. Although rater self-construal significantly influenced overall performance evaluations, no such effects were observed for specific dimension ratings. Implications of these results for performance appraisal research and practice are discussed.
