A friend is a present you give to your “Self”: Avoidance of intimacy moderates the effects of friends on self-liking

The current research proposes that thinking about friends improves feelings about the self and does so differentially depending on avoidance of intimacy. Based on previous findings that individuals who avoid intimacy in relationships (avoidant individuals) contrast their self-concepts with primed friends whereas those who pursue intimacy in relationships (non-avoidant individuals) assimilate their self-concepts to primed friends [Gabriel, S., Carvallo, M., Dean, K., Tippin, B. D., & Renaud, J. (2005). How I see “Me” depends on how I see “We”: The role of avoidance of intimacy in social comparison. Personality and Social Psychology Bulletin, 31, 156-157], we predicted that friends who embody negative aspects of self would lead avoidant individuals to like themselves more, whereas friends who embody positive aspects of self would lead non-avoidant individuals to like themselves more. A pretest determined that good friends were seen as more similar to positive and ideal aspects of the self, whereas friends about whom participants had more mixed feelings (ambivalent friends) were seen as more similar to disliked and feared aspects of the self. Four experiments supported the main hypotheses. In Experiment 1, non-avoidant individuals like themselves more when good friends were primed. In Experiment 2, avoidant individuals like themselves more when ambivalent friends were primed. In Experiment 3, non-avoidant individuals liked themselves better after thinking about a friend’s positive traits, whereas avoidant individuals liked themselves better after thinking about a friend’s negative traits. In Experiment 4, all individuals under self-esteem threat strategically brought friends to mind who would help them like themselves more.     

Jugendgewalt als Lebensbewältigungsprozess

Aggression und Gewalt bei Jugendlichen stilisieren sich zum Sinnbild für unsere „kranke Gesellschaft“. Was sich bei jüngeren Jugendlichen noch – oft als Lausbuben-Verhalten bagatellisiertes – Herumschubsen und Rangeln im Pausenhof ?u?ert, tritt in Form von Bullying und Mobbing immer st?rker zutage. Jugendliche, die trinken, stehlen, Drogen zu sich nehmen, Mitschüler oder Gruppenmitglieder bedrohen und Gegenst?nde ?ffentlichen Gutes besch?digen etc., stehen auf der Tagesordnung. Selbst Erpressung von Mitschülern ist kein Einzeldelikt mehr.

Methodological and empirical issues when dissociating cue-related from task-related processes in the explicit task-cuing procedure

In the explicit cuing version of the task-switching paradigm, each individual task is indicated by a unique task cue. Consequently, a task switch is accompanied by a cue switch. Recently, it has been proposed that priming of cue encoding contributes to the empirically observed switch costs. This proposal was experimentally supported by using a 2:1 mapping of cues to tasks, so that a cue switch does not necessarily imply a task switch. The results indeed suggested a substantial contribution of “cue-switch costs” to task-switch costs. Here we argue that the 2:1 mapping potentially leads to an underestimation of “pure” task-switch costs. To support this argument, we report the results of a new study in which we used “transition cues” that indicate the identity of the current task based on the identity of the preceding task. This new type of cue allows a full factorial manipulation of cue switches and task switches because it includes the condition in which a cue repetition can also indicate a task switch (i.e., when the “switch” cue is repeated). We discuss the methodological implications and argue that the present approach has merits relative to the previously used 2:1 mapping of cues to tasks.     

Leitlinie für die Begutachtung von Schmerzen

The present guidelines for expert testimony have been elaborated for the first time in 2004 by medico-legal representatives from several German professional academic societies (neurology, orthopedic surgery, psychiatry, psychosomatic medicine, psychotherapy). Their aim is to standardize the course and the content of expert testimony in subjects, who complain about chronic pain as the leading symptom for seeking pension or other compensation. In 2006, the guidelines have been revised and completed by adding detailed data about classification and prognosis of chronic pain, about causality questions, and about estimation of functional impairment in different legal areas.     

Right-handers' reaching in contralateral hemispace: a kinematic observation

C. Gabbard and C. Helbig (2004) found, when examining seated participants' limb selection for reaching and grasping in hemispace, that right-handers preferred to switch to the nondominant left arm for objects located approximately 20 degrees horizontally from body midline (90 degrees) in left hemispace. In the present study, the authors examined 13 strongly lateralized seated right-handers' kinematics of reaching to object positions ranging from body midline to 40 degrees horizontally in left hemispace. Participants executed faster reaches with the left arm than with the right arm to objects placed 20 degrees-40 degrees from midline, whereas they did not change the proportion of time they spent accelerating the hands when the position of the object changed. A 2nd main finding was an increase in the left hand's trajectory curvature as object position moved farther from midline, with a corresponding decrease in the contribution of upper-arm motion to the reach. Those observations suggest that the switch from dominant right-arm reaching to nondominant left-arm reaching in left hemispace reported in the aforementioned study may have emerged from a shift from a shoulder-driven reach to an elbow-driven action.     

Detection of visual stimuli in correlated noise

The hypothesis of detection by temporal probability summation (TPS) as characterised in Mortensen [(2007). An analysis of visual detection by temporal probability summation, submitted for publication] is critically evaluated, considering data from an experiment of Roufs and Blommaert [(1981). Temporal impulses and step responses of the human eye obtained psychophysically by means of a drift-correcting perturbation technique. Vision Research, 21, 1203-1221], who derived the impulse and the step response for a sustained type of channel. The assumed approximate linearity of the channel is discussed with respect to recent findings from neurophysiological investigations. The data are shown not to be compatible with the TPS-postulate. Further, a model of a cell assembly, consisting of a homogeneous set of neurons, is presented that allows for a natural interpretation of random fluctuations in case of temporal peak detection (TPD). The model may be discussed with respect to TPS as well as to TPD; in any case, the model allows to integrate some results concerning the effects of attentional focussing on the detection process.     

The effects of wording on the understanding and use of uncertainty information in a threshold forecasting decision

Many believe that information about small chances of severe weather would be useful to the general public for precautionary action. What is the best way to explain this kind of information to a non‐expert audience? The studies reported here investigated effects of framing (negative vs. positive), format (frequency vs. probability), likelihood (low vs. high) and compatibility (task‐match) on interpretation of verbal expressions of forecast uncertainty and on subsequent forecasting decisions. The crucial factor was the match between the verbal expression and the overall task goal. Errors increased when there was a mismatch between the expression (e.g. winds less than 20 knots) and the task (e.g. post an advisory when winds will exceed 20 knots). However, framing and format had little impact. We conclude that consideration of user expectations arising from the overall task goal is crucial in explaining uncertainty information to a naïve audience. Global expectations overpower other potential effects. Copyright © 2008 John Wiley & Sons, Ltd.
