Justice sensitivity and forgiveness in close interpersonal relationships: the mediating role of mistrustful, legitimizing, and pro-relationship cognitions

The purpose of the present investigation was to explore and better understand the relationship between justice sensitivity from a victim's perspective (JS‐victim) and interpersonal forgiveness. In particular, we aimed to identify the cognitive mechanisms mediating this relationship and test the moderating influence of post‐transgression perpetrator behavior. We used data from a questionnaire study employing a Swiss community sample (N = 450) and 2 scenario‐based studies employing German online samples, in the context of romantic (N = 242) and friendship relationships (N = 974). We consistently found JS‐victim to be negatively related to dispositional (Study 1) and situational forgiveness (Studies 2 and 3). Study 2 demonstrated the relationship between JS‐victim and reduced forgiveness to be partly mediated by mistrustful interpretations of the partner's post‐transgression behavior. In Study 3, cognitions legitimizing one's own antisocial reactions and a lack of pro‐relationship cognitions were identified as further mediators. These variables mediated the negative effect of JS‐victim on forgiveness largely independent of whether the friend perpetrator displayed reconciliatory behavior or not. Findings suggest that the cognitive mechanisms mediating victim‐sensitive individuals' unforgiveness could barely be neutralized. Future research should investigate their malleability in light of qualitatively different perpetrator behaviors as well as their broader relational implications.     

Brain dopamine and kinematics of graphomotor functions

Three experiments were performed in an attempt to achieve a better understanding of the effect of dopamine on handwriting. In the first experiment, kinematic aspects of handwriting movements were compared between healthy participants and patients with Parkinson's disease (PD) on their usual dopaminergic treatment and following withdrawal of dopaminergic medication. In the second experiment, the writing performance of healthy participants with a hyperechogenicity of the substantia nigra as detected by transcranial sonography (TCS) was compared with the performance of healthy participants with low echogenicity of the substantia nigra. The third experiment examined the effect of central dopamine reduction on kinematic aspects of handwriting movements in healthy adults using acute phenylalanine and tyrosine depletion (APTD). A digitising tablet was used for the assessment of handwriting movements. Participants were asked to perform a simple writing task. Movement time, distance, velocity, acceleration and measures of fluency of handwriting movements were measured. The kinematic analysis of handwriting movements revealed that alterations of central dopaminergic neurotransmission adversely affect movement execution during handwriting. In comparison to the automatic processing of handwriting movements displayed by control participants, participants with an altered dopaminergic neurotransmission shifted from an automatic to a controlled processing of movement execution. Central dopamine appears to be of particular importance with regard to the automatic execution of well-learned movements.     

Relationship between social anxiety and perceived trustworthiness

Four different patterns of biased ratings of facial expressions of emotions have been found in socially anxious participants: higher negative ratings of (1) negative, (2) neutral, and (3) positive facial expressions than nonanxious controls. As a fourth pattern, some studies have found no group differences in ratings of facial expressions of emotion. However, these studies usually employed valence and arousal ratings that arguably may be less able to reflect processing of social information. We examined the relationship between social anxiety and face ratings for perceived trustworthiness given that trustworthiness is an inherently socially relevant construct. Improving on earlier analytical strategies, we evaluated the four previously found result patterns using a Bayesian approach. Ninety-eight undergraduates rated 198 face stimuli on perceived trustworthiness. Subsequently, participants completed social anxiety questionnaires to assess the severity of social fears. Bayesian modeling indicated that the probability that social anxiety did not influence judgments of trustworthiness had at least three times more empirical support in our sample than assuming any kind of negative interpretation bias in social anxiety. We concluded that the deviant interpretation of facial trustworthiness is not a relevant aspect in social anxiety.     

Now you see it,now you don't: The context dependent nature of category-effects in visual object recognition

In two experiments, we test predictions regarding processing advantages/disadvantages for natural objects and artefacts in visual object recognition. Varying three important parameters—degree of perceptual differentiation, stimulus format, and stimulus exposure duration—we show how different category-effects can be provoked in normal subjects on the same task. We interpret the results in light of the Pre-semantic Account of Category Effects (PACE; Gerlach, 2009), and conclude that category-effects do not reflect absolute processing differences between categories. Rather, category-effects are products of common operations which are differentially affected by the structural similarity among objects (with natural objects being more structurally similar than artefacts). The potentially most important aspect of the present study is the demonstration that category-effects are very context dependent; an aspect which has been neglected in earlier literature on category-specificity. PACE provides a useful framework in this respect, as it specifies how category-effects are influenced by changes in task and stimulus characteristics.     

Evidenzbasierte Psychotherapie der Panikst?rung mit und ohne Agoraphobie

From the evidence reported in the recent guidelines [Heinrichs et al. (2009) Evidenzbasierte Leitlinie zur Psychotherapie der Panikst?rung mit und ohne Agoraphobie. Hogrefe, G?ttingen] the following conclusions can be drawn with respect to the treatment of panic disorder with or without agoraphobia, as well as for agoraphobia without panic disorder:

1. Every psychotherapy should be preceded by suitable diagnostics and a case formulation.
2. The effectiveness of every psychotherapy should be evaluated with well established measures.
3. For the treatment of panic disorder without agoraphobia, cognitive behavioral treatment (CBT) and applied relaxation have been shown to be effective (evidence grade 1).
4. For panic disorder with agoraphobia, CBT, combination treatment (CBT plus medication), as well as panic-focused psychodynamic psychotherapy in the outpatient setting have shown short-term effectiveness (evidence grade 1). Longer lasting effects have been documented for CBT (evidence grade 1).
5. For agoraphobia without panic disorder, CBT with a focus on situational exposure can be recommended (evidence grade 1).

     

Blushing and physiological arousability in social phobia

Blushing is the most prominent symptom of social phobia, and fear perception of visible anxiety symptoms is an important component of cognitive behavioral models of social phobia. However, it is not clear how physiological and psychological aspects of blushing and other somatic symptoms are linked in this disorder. The authors tested whether social situations trigger different facial blood volume changes (blushing) between social phobic persons with and without primary complaint of blushing and control participants. Thirty social phobic persons. 15 of whom were especially concerned about blushing, and 14 control participants were assessed while watching an embarrassing videotape, holding a conversation, and giving a talk. Only when watching the video did the social phobic persons blush more than controls blushed. Social phobic persons who complained of blushing did not blush more intensely than did social phobic persons without blushing complaints but had higher heart rates, possibly reflecting higher arousability of this subgroup.     

The impact of visual flow stimulation on anxiety, dizziness, and body sway in individuals with and without fear of heights

Individuals with acrophobia experience anxiety and dizziness when exposed to heights. It may be that their balance system is disturbed and that they therefore have to rely more strongly on visual information.We tested this hypothesis by exposing 20 individuals with high fear of heights and 20 healthy control participants to nine different visual flow stimuli through a head mounted display, thereby inducing a conflict between visual input and somatosensory information. Anxiety and dizziness were assessed repeatedly by means of self-reports, while resultant body sway was measured continuously with a force plate individuals stood on.Individuals with fear of heights felt more anxious and dizzier, and also showed stronger body sway than healthy control participants.Merely receiving visual balance information contradictory to somatosensory balance information is sufficient to induce anxiety, dizziness, and body sway in individuals with fear of heights. An underlying balance dysfunction may contribute to the development of height phobia.
