A Visual Representation and the Control of Manual Aiming Movements

Three experiments were conducted to determine if a representation of the movement environment is functional in the organization and control of limb movements, when direct visual contact with the environment is prevented. In Experiment 1, a visual rearrangement procedure was employed to show that a representation of the environment that provides inaccurate information about the spatial location of a target can disrupt manual target aiming. In Experiment 2, we demonstrated that spatial information about the position of a target can be destroyed by a visual pattern mask, supporting our claim that the representation is visual. A target-cuing procedure was used in Experiment 3 to show that representation of target position can be useful for premovement organization in a targetaiming task. Together our findings suggest that a short-lived visual representation of the movement environment may serve a useful role in the organization and control of limb movements.     

Connected and Isolated Victims of Relational Aggression: Associations with Peer Group Status and Differences between Girls and Boys

Some adolescents who are relationally victimized by gossip and ostracism have limited close connections to a peer or friendship group, but victimization also can be group-based, occurring between or within friendship groups. The purpose of this study was to test gender differences in these two forms of victimization, referred to as isolated and connected victimization, and to test associations of each form with peer status (social prominence and preference within the peer group) and aggressive behavior. We expected that associations between victimization, especially connected victimization, peer status and aggressive behavior would differ for boys and girls. Australian students (N = 335, M _age = 12.5 years) self-reported victimization, and nominated peers who were victimized, accepted, rejected, socially prominent, and unpopular. Connected and isolated forms of victimization were correlated, but differences were found in their correlations with other measures and by gender. Especially when reported by peers, adolescents higher in connected victimization were also higher in both aggression and social prominence (i.e., they were more popular and considered leaders); yet, they were also more disliked (rejected). In contrast to connected victimization, isolated victimization was associated with negative peer status only, and weakly and inconsistently associated with aggression. Finally, gender moderation was found, which showed a pattern of aggression, prominence and dislike among adolescent females who were connected victims, but this pattern was not nearly as pronounced in their male counterparts.     

Emotion work and job stressors and their effects on burnout

Abstract

This article reports research on emotion work, organizational as well as social variables as predictors of job burnout. In burnout research, high emotional demands resulting from interactions with clients are seen as a core characteristic of service jobs. However, these emotional demands were seldom measured in a direct manner. It was only recently that emotional demands were included in studies on burnout referring to the concept of emotion work (emotional labor). Emotion work is defined as the requirement to display organizationally desired emotions. A multi-dimensional concept of emotion work was used to analyze the relations of emotion work variables with organizational and social variables and their joint effect on burnout in five samples including employees working in children's homes, kindergartens, hotels, banks and call centers. Emotion work variables correlated with organizational stressors and resources. However, hierarchical multiple regression showed a unique contribution of emotion work variables in the prediction of burnout. Moreover, the analysis of interaction effects of emotional dissonance and organizational and social stressors showed that for service professionals, the coincidence of these stressors led to exaggerated levels of emotional exhaustion and depersonalization.     

Can You Feel It? Negative Emotion,Risk, and Narrative in Health Communication

Eliciting emotional responses to mass media messages can be an effective means of changing public health attitudes, intentions and behaviors. This conceptual paper proposes that emotional responses to such media messages can be message-referent, plot-referent, and/or self-referent. Self-referent emotional responses are expected to have a direct effect in motivating behavior change, particularly as they are likely to be associated with an increase in perceived personal risk. Message-referent and plot-referent emotional responses are proposed to have indirect effects on the individual, primarily by stimulating self-referent emotions, and prompting interpersonal discussion about the message. In this paper, it is argued that narrative is a particularly effective message format with which to elicit self-referent emotional responses.     

Distracted by Details: Narrative Influence Following Conflicting Stories

Work on narrative influence has demonstrated that stories can have a strong effect on people's thoughts and attitudes. However, existing research has not addressed how people respond to multiple stories endorsing different conclusions. The current studies examined how reading two conflicting narratives influences people's decisions about a subsequent situation, with particular emphasis on how resemblances between the narratives and the situation moderate the effects. Across two studies, participants read two testimonials that described the successful use of different treatments for a medical disorder. Participants subsequently made treatment recommendations for a patient who resembled one of the testimonials in treatment-relevant ways. The key manipulation was whether the patient also resembled the other testimonial in treatment-irrelevant ways. Both studies found that these distracting, irrelevant similarities led to less appropriate treatment recommendations. The effect on decision confidence, however, was less clear, with some suggestion of both an increase (Study 1) and a decrease (Study 2) in confidence.     

Multicriteria Classification with Unknown Categories: A Clustering–Sorting Approach and an Application to Conflict Management

This work proposes an approach to cluster and sort a set of alternatives considering multi‐criteria categories with a partial order structure. It can be considered a heuristic approach because it does not attempt to derive an optimal partial order among all conceivable clusters of alternatives. Rather than this, it intends to be a simple approach that is transparent to the Decision Maker (DM) whose assistance is sought to help shaping the results. The approach proposed arises from the conjugation of traditional Clustering analysis and Multi‐criteria sorting tools. At the outset, the number of categories and their characteristics is unknown. First, we need to detect only the clusters themselves on the basis of a similarity measure independent of the preferences of the DM. Next, we detect potential partial order relations that might exist between them, according to the subjective preferences of the DM. Such preferences are elicited only after the DM has examined the clusters detected and deemed that these categories made sense. The new approach performs very well in a real‐world problem of management of intragroup conflicts and conflict handling strategies. Copyright © 2012 John Wiley & Sons, Ltd.     

ENHANCING THE ACCURACY OF LOW‐FREQUENCY BEHAVIOR DATA COLLECTION BY DIRECT‐CARE STAFF

Accurate data collection on low‐frequency problem behavior is imperative given the paucity of opportunities to observe, record, and assess responding. Infrequently occurring behavior also provides a challenge for staff training relative to data collection. The present study evaluated the use of task clarification and feedback to teach direct‐care staff members to take data on recorded, simulated problem behavior. Results indicated that the procedures were effective in increasing accuracy not only in the contrived scenarios but also for problem behavior in the natural environment. These data suggest that task clarification and feedback on simulated problem behavior may be an effective method to increase accurate data collection on problem behavior in the natural environment.

Understanding the multiframe caricature advantage for recognizing facial composites

Eyewitnesses often construct a “composite” face of a person they saw commit a crime, a picture that police use to identify suspects. We described a technique (Frowd, Bruce, Ross, McIntyre, & Hancock, 2007) based on facial caricature to facilitate recognition of these images: Correct naming substantially improves when composites are seen with progressive positive caricature, where distinctive information is enhanced, and then with progressive negative caricature, the opposite. Over the course of four experiments, the underpinnings of this mechanism were explored. Positive-caricature levels were found to be largely responsible for improving naming of composites, with some benefit from negative-caricature levels. Also, different frame-presentation orders (forward, reverse, random, repeated) facilitated equivalent naming benefit relative to static composites. Overall, the data indicate that composites are usually constructed as negative caricatures.     

The role of attention in subitizing: Is the magical number 1?

Subitizing, the fast and accurate enumeration of up to about 3 or 4 objects, has often been thought to be dependent on limited-capacity preattentive mechanisms. We used an attentional blink paradigm to investigate the extent to which subitizing requires attentional resources. On each trial, subjects identified a target letter in an RSVP stream and then enumerated dots presented in the stream that were either simultaneous with the target letter or followed it by up to 400 ms. For numerosities from 2 to 9, evidence of an attentional blink was observed; only enumeration of 0 or 1 elements was independent of lag. Thus, even enumeration of 2–3 objects, which is within the traditional subitizing range, appears to require attentional resources. The relation of this work to studies on the attentional requirements of detecting a unique item among distractors, a supposedly preattentive discrimination, is briefly discussed.
