Social comparison processes in organizations

We systematically analyze the role of social comparison processes in organizations. Specifically, we describe how social comparison processes have been used to explain six key areas of organizational inquiry: (1) organizational justice, (2) performance appraisal, (3) virtual work environments, (4) affective behavior in the workplace, (5) stress, and (6) leadership. Additionally, we describe how unique contextual factors in organizations offer new insight into two widely studied sub-processes of social comparison, acquiring social information and thinking about that information. Our analyses underscore the merit of integrating organizational phenomena and social comparison processes in future research and theory.     

Parent and Teacher Ratings of Attention-Deficit/Hyperactivity Disorder in Preschool: The ADHD Rating Scale-IV Preschool Version

Efforts for early identification and intervention for children with AD/HD have necessitated the development of rating scales of behavior for the preschool population. The standardization, reliability, and validity data were presented for the ADHD Rating Scale-IV Preschool Version. Parent and teacher ratings were collected on 902 and 977 children 3 to 5 years of age, respectively. Raw scores for the Inattention, Hyperactivity/Impulsivity and Total scores were converted to T-Scores and percentile ranks. Reliability coefficients ranged from 0.80 to 0.95 indicating good test–retest reliability. Concurrent validity with the Conners Teacher Rating Scales: Revised-Short and Conners Parent Rating Scale: Revised-Short ranged from 0.54 to 0.96. The ADHD-Rating Scale-IV appears to be a reliable, valid and user friendly measure for screening preschoolers with behavior problems. Future research is needed to validate its widespread use as a screening and diagnostic tool.     

病理诊断的局限及其应对措施

病理诊断是诊断疾病的基本方法之一,是许多疾病的最终诊断,被许多人称为临床诊断的“金标准”。但由于病理诊断技术存在的一些主观和客观因素的影响,病理诊断也存在局限性,并且这些诊断的局限常常会引起误诊漏诊和医患纠纷。如何能在工作中尽可能地克服病理诊断的局限,使其更好地为临床和患者服务。结合临床病理实践的具体工作,对病理诊断的局限性进行简要分析,并提出相关的应对措施。     

The defeasible nature of coherentist justification

The impossibility results of Bovens and Hartmann (2003, Bayesian epistemology. Oxford: Clarendon Press) and Olsson (2005, Against coherence: Truth, probability and justification. Oxford: Oxford University Press.) show that the link between coherence and probability is not as strong as some have supposed. This paper is an attempt to bring out a way in which coherence reasoning nevertheless can be justified, based on the idea that, even if it does not provide an infallible guide to probability, it can give us an indication thereof. It is further shown that this actually is the case, for several of the coherence measures discussed in the literature so far. We also discuss how this affects the possibility to use coherence as a means of epistemic justification.     

Testing 1, 2, 3, …4? The personality of repeat SAT test takers and their testing outcomes

The current study considered the correlates of test retaking. In particular, the personality trait of neuroticism was proposed to be related to retaking the SAT test. Results revealed that, accounting for initial SAT score and the other Big Five factors of personality, neuroticism predicted the number of times an individual took the SAT before attending college. Further, the results of a latent growth model indicated that, for those who retook the SAT, test scores showed improvement over time. None of the Big Five predicted changes in SAT scores. Results are discussed in light of the possible benefits of high levels of neuroticism for SAT score improvement.     

A computational model of fractionated conflict-control mechanisms in task-switching

A feature of human cognition is the ability to monitor and adjust one's own behavior under changing circumstances. A dynamic balance between controlled and rapid responding is needed to adapt to a fluctuating environment. We suggest that cognitive control may include, among other things, two distinct processes. Incongruent stimuli may drive top-down facilitation of task-relevant responses to bias performance toward exploitation vs. exploration. Task or response switches may generally slow responses to bias toward accuracy vs. speed and exploration vs. exploitation. Behavioral results from a task switching study demonstrate these two distinct processes as revealed by higher-order sequential effects. A computational model implements the two conflict-control mechanisms, which allow it to capture many complex and novel sequential effects. Lesion studies with the model demonstrate that the model is unable to capture these effects without the conflict-control loops and show how each monitoring component modulates cognitive control. The results suggest numerous testable predictions regarding the neural substrates of cognitive control.     

On the predictive validity of indirect attitude measures: Prediction of consumer choice behavior on the basis of affective priming in the picture-picture naming task

Recent studies have revealed that robust and replicable affective priming of naming responses can be obtained when pictures are used as primes and targets. The aim of the present research was to examine the predictive validity of affective priming effects that are obtained with the picture-picture naming task. In two studies that were modeled after [Karpinski, A., & Hilton, J. L. (2001). Attitudes and the Implicit Association Test. Journal of Personality and Social Psychology, 81, 774-778], we observed that individual difference scores that are obtained with the naming task exhibit good predictive validity. Both practical and theoretical implications of this finding are discussed.     

Goal orientation and performance adaptation: A meta-analysis

The relationship between goal orientation and performance adaptation across studies was assessed in the present article. The relevance of performance adaptation can be exemplified by the desire to optimize performance and mitigate the negative effects of change in organizational and educational contexts (i.e. new co-workers, new software, emergencies). Three-level meta-analyses were conducted for learning goal orientation (LGO) and performance goal orientation (PGO). Furthermore, within PGO a distinction between avoid performance goal orientation (APGO) and prove performance goal orientation (PPGO) could be made. In moderator analyses the influence of measurement method of performance adaptation (subjective ratings vs objective scores) was assessed amongst others. Although significant effects were found they were primarily visible for subjective ratings and not objective scores.
