Assessing research on workplace violence, 2000–2012

Since the highly publicized U.S. Postal violence cases in the 1980s, workplace aggression and workplace violence have been the source of much public discussion and concern. Yet, the topic has only recently received sustained empirical attention—most of which has come from the organizational management and business fields. This article provides a review of the empirical research literature on workplace violence in several databases from 2000 to 2012. Our review uncovers that different occupational domains have different experiences with workplace violence, while some occupations are subject to distinct types of violence by unique aggressors. Directions for future theoretical and empirical research are highlighted.     

Creativity in Context; The Courage in Therivel’s GAM/DP

The desire to quantify and categorize creativity so that we can easily identify the individual characteristics which serve as its precursors is one which authors have been attempting to successfully complete for some time. In this light, William Therivel’s High Creativity Unmasked, discusses how his GAM/DP theory accounts for highly creative people from history as well as a rationale for the rise and fall of creativity in selected cultures throughout history. By examining the latest published work on how Genetic Endowment, Assistances, Misfortunes and Divisions of Power, and how they relate to creativity, Therivel proposes unique rationales for the rises and declines of cultures. This paper examines how creativity and courage work together and in some cases side by side, to explain more fully the role of creativity in culture. This article examines some of Therivel’s examples and provides alternate explanations for the phenomena he ascribes to the decline of creativity. In addition, the complexity of both creativity and courage are discussed, both in the current context, and in the next steps for research and theoretical discussion.     

Context and Prior Impression Effects on Attention, Judgment Standards, and Ratings: Contrast Effects Revisited

The present study extended research on contrast effects by (a) examining the effect of context performances on ratings of a target performance when a prior impression of the target performer already exists, and (b) clarifying the issue of whether contrast is caused by attention to context-discrepant behavior or shifts in judgment standards. The results demonstrated that the existence of a prior impression mitigates the influence of context performances on ratings. Judgment standards were found to be unstable and dependent on information provided to raters by the experimental manipulations. Regression analyses showed that both attention and standards of judgment mediate the relationship between context and ratings. Implications of these findings for contrast effects, performance ratings, and the importance of reliable judgment standards for real-world performance appraisals are discussed.     

Confidence at the group level of analysis: A longitudinal investigation of the relationship between potency and team effectiveness

Our longitudinal field study investigated the relationship between team potency and team effectiveness. The sample for this study was drawn from 71 change management teams from an automotive firm in the USA. Team potency ratings were obtained from team members. Team effectiveness ratings were obtained from team members, team leaders and external raters. Results indicated that team effectiveness and team potency are reciprocally and longitudinally related (p< .01).     

Mediation in a sibling context: the relations of older siblings' mediating behaviour and younger siblings' task performance

We investigated the sibling relationship as a context for cognitive development. Forty preschoolers (ages 5–6) and their younger siblings (ages 2–3) were visited at home. Four games were presented to the older siblings and they were asked (a) to estimate how well their younger sibling will perform on each game and (b) to teach the younger sibling how to use the games. The older siblings' mediating behaviours during the teaching session and the younger siblings' performance on the four tasks were coded. The frequency of mediating behaviours—including attention focusing, amplifying affect and providing meaning, fostering a sense of competence, regulating of the learning process, de‐contextualization, and negative feedback in the form of mocking and laughing at errors, predicted the younger siblings' task performance. The older sibling's accurate perception of the younger child's competence was uniquely predictive of task performance. The highest amount of mediation was observed in older‐brother–younger‐brother pairs, in particular the behaviours of negative feedback and amplifying affect. Results contribute to the discussion on the role of siblings as moderators of cognitive development and are discussed in terms of Vygotsky's cultural–historical perspective on apprenticeship.

Enforcing Social Conformity: A Theory of Authoritarianism

Fifty years after the publication of The Authoritarian Personality, the empirical literature on authoritarianism continues to grow even though there is no widely accepted theory to account for the phenomenon. The absence of a secure theoretical grounding severely limits our understanding of authoritarianism. This paper offers a new conceptualization in which authoritarian predispositions originate in the conflict between the values of social conformity and personal autonomy. Prejudice and intolerance should be observed among those who value social conformity and perceive a threat to social cohesion. These hypotheses were tested with a sample of undergraduate students; the questionnaire included new measures of the dimension of social conformity–autonomy as well as items from Altemeyer's RWA (right–wing authoritarianism) scale.     

Infant–mother and infant–father synchrony: The coregulation of positive arousal

To examine the coregulation of positive affect during mother–infant and father–infant interactions, 100 couples and their first‐born child were videotaped in face‐to‐face interactions. Parents' and infant's affective states were coded in one‐second frames, and synchrony was measured with time‐series analysis. The orientation, intensity, and temporal pattern of infant positive arousal were assessed. Synchrony between same‐gender parent–infant dyads was more optimal in terms of stronger lagged associations between parent and infant affect, more frequent mutual synchrony, and shorter lags to responsiveness. Infants' arousal during mother–infant interaction cycled between medium and low levels, and high positive affect appeared gradually and was embedded within a social episode. During father–child play, positive arousal was high, sudden, and organized in multiple peaks that appeared more frequently as play progressed. Mother–infant synchrony was linked to the partners' social orientation and was inversely related to maternal depression and infant negative emotionality. Father–child synchrony was related to the intensity of positive arousal and to father attachment security. Results contribute to research on the regulation of positive emotions and describe the unique modes of affective sharing that infants coconstruct with mother and father. ©2003 Michigan Association for Infant Mental Health.     

Validation of the Multidimensional Blood/Injury Phobia Inventory: Evidence for a Unitary Construct

The Multidimensional Blood/Injury Phobia Inventory (MBPI) was developed from a theoretical framework to characterize a broad range of feared stimuli and phobic reactions associated with this pathology. The MBPI consists of 40 items that cross 4 types of stimulus content (injections, hospitals, blood, injury), 5 types of phobic responses (fear, avoidance, worry, fainting, disgust), and a self versus other focus. This study reports on administration of the MBPI to 558 undergraduates, 9 of whom had blood/injury phobia. The instrument had a Cronbach's alpha of .91 and demonstrated good concurrent validity, convergent validity, and discriminant validity. One large factor emerged in an unrotated principal components analysis, suggesting that blood/injury phobia is a unitary psychometric construct. Exploratory factor analyses revealed a 6-factor solution defined by stimulus content domains and fainting, each of which may be important to consider clinically when assessing the unique concerns of treatment-seeking individuals.     

The simplicity principle in human concept learning

How do we learn concepts and categories from examples? Part of the answer might be that we induce the simplest category consistent with a given set of example objects. This seemingly obvious idea, akin to simplicity principles in many fields, plays surprisingly little role in contemporary theories of concept learning, which are mostly based on the storage of exemplars, and avoid summarization or overt abstraction of any kind. This article reviews some evidence that complexity minimization does indeed play a central role in human concept learning. The chief finding is that subjects' ability to learn concepts depends heavily on the concepts' intrinsic complexity; more complex concepts are more difficult to learn. This pervasive effect suggests, contrary to exemplar theories, that concept learning critically involves the extraction of a simplified or abstracted generalization from examples.
