Haptic perception of parallelity in the midsagittal plane.

Previous studies [Perception 28 (1999) 1001; Perception 28 (1999) 781] on the haptic perception of parallelity on a horizontal plane showed that what subjects haptically perceive as being parallel deviates considerably from what is physically parallel. The deviations could be described with a subject-dependent orientation gradient in the left-right direction. The gradients found in the bimanual conditions were significantly larger (about 70%) than those in the unimanual conditions. The questions to be answered in the present study are the following: (1) Does the haptic perception of parallelity in the midsagittal plane also show systematic deviations from veridicality? (2) Are the unimanual and bimanual performances again quantitatively but not qualitatively different? The set-up consisted of a plate positioned in the midsagittal plane of the subject. The subject touched the right side of the plate with his/her right hand and the left side with the left hand. The results show again large systematic deviations. The major part of the deviations can be described by means of a subject-dependent orientation gradient in the vertical direction. The quantitative (but not qualitative) difference between the unimanual and the bimanual conditions is much larger in the midsagittal plane than in the horizontal plane.     

Revisiting the mediating role of leader–member exchange in transformational leadership: the differential impact model

Transformational leadership (TFL) has been proposed as an essential antecedent of leader–member exchange (LMX), which in turn affects outcomes in organizations. We extend this mediation hypothesis in two ways by proposing a differential impact model, which we test on three organizational outcomes: employee job satisfaction, employee organizational commitment, and leader effectiveness. First, we extend LMX’s mediational impact—which has previously only been tested for employee outcomes—to leader effectiveness. Second, we argue that this mediation will be stronger for outcomes that are more proximal rather than distal to dyadic relations between leader and followers (high proximity: job satisfaction; medium proximity: organizational commitment; low proximity: leader effectiveness). Meta-analytic structural equation modelling based on 132 studies revealed that LMX mediates TFL’s relationships with employee outcomes (more strongly for job satisfaction than for commitment), but not with leader effectiveness, whereas TFL showed a stronger direct link to leader effectiveness. The findings suggest that TLF and LMX contribute differentially to organizational outcomes depending on their proximity to dyadic relations between leaders and followers. The differential impact model uncovers leadership effectiveness processes, integrates influential leadership theories, and highlights the importance of distinguishing between different outcome measures and the processes facilitating them.     

Coping with threats to self-esteem: the differing patterns of subjects with high versus low trait self-esteem in first-person accounts

Based on retrospective self-reports, strategies of coping with threats to self-esteem in close relationships were investigated in a sample of 412 adults in south-west Germany. Results indicate that self-esteem was negatively associated with experiencing failure or criticism as a threat to self-esteem. There was a positive association between participants' self-esteem and their self-reported tendency to approach the problem optimistically and act in a rational manner. Self-esteem was negatively associated with feeling dependent on the partner and with treating the partner in a hostile way. As far as women were concerned, self-esteem was also positively related to coping effectiveness. In the case of men the results were less clear. It is suggested that the self-defeating coping style associated with low self-esteem may be self-perpetuating. © 1998 John Wiley & Sons, Ltd.     

THE WORLDWIDE BURDEN OF INFANT MENTAL AND EMOTIONAL DISORDER: REPORT OF THE TASK FORCE OF THE WORLD ASSOCIATION FOR INFANT MENTAL HEALTH

Children worldwide experience mental and emotional disorders. Mental disorders occurring among young children, especially infants (birth –3 years), often go unrecognized. Prevalence rates are difficult to determine because of lack of awareness and difficulty assessing and diagnosing young children. Existing data, however, suggest that rates of disorders in young children are comparable to those of older children and adolescents (von Klitzing, Dohnert, Kroll, & Grube, 2015 ). The lack of widespread recognition of disorders of infancy is particularly concerning due to the unique positioning of infancy as foundational in the developmental process. Both the brain and behavior are in vulnerable states of development across the first 3 years of life, with potential for enduring deviations to occur in response to early trauma and deprivation. Intervention approaches for young children require sensitivity to their developmental needs within their families. The primacy of infancy as a time of unique foundational risks for disorder, the impact of trauma and violence on young children's development, the impact of family disruption on children's attachment, and existing literature on prevalence rates of early disorders are discussed. Finally, global priorities for addressing these disorders of infancy are highlighted to support prevention and intervention actions that may alleviate suffering among our youngest world citizens.     

Psychotherapeutische Kurzintervention bei somatisierenden Patienten im Krankenhaus

The manual describes the psychotherapeutic procedure for somatizing patients who are admitted to hospital for diagnostics and therapy of unclear physical complaints. An essential goal of the psychotherapeutic interventions is to achieve an understanding for the disease, in which body, psyche and social relationships are experienced as interrelated. By addressing the health fears and subjective concepts about the onset and maintenance of his physical complaints, the patient feels that he is being taken seriously and understood. Connections between physical symptoms and the suppression of undesirable affects like anger, rage and disappointment are verbalized and understood in greater depth, based on body perception exercises and a symptom diary. The positive experience of understanding and symptom relief obtained in the psychotherapeutic sessions is used for the main goal of the intervention: to motivate the (out- and in-)patient for a regular psychotherapy. Experience up to now has shown that three to five sequential sessions of about 45–60 minutes suffice to attain this therapy goal. Implementation is most successful within an established consultant or liaison service in close cooperation with the ward doctors.     

Destruktivit?t in Paarbeziehungen Paartherapeutische Behandlungsm?glichkeiten

Streitende Paare, die in destruktiven Kommunikationsmustern gefangen sind lösen oft schwierige Situationen in einer Paartherapie aus. Die Kommunikationsmuster reichen von verbalen Entwertungen und Beschimpfungen bis hin zu gewalttätigen Auseinandersetzungen. Damit der Therapeut bzw. die Therapeutin handlungsfähig bleiben, müssen sie über Erklärungsmodelle zur Entstehung und Aufrechterhaltung destruktiver Interaktionszirkel verfügen. Darüber hinaus benötigen sie Handwerkszeug und konkrete Interventionsmöglichkeiten zur Deeskalation bzw. zur Unterbrechung dieser destruktiven Muster.     

The multifactor offender readiness model

There has been a resurgence of interest in the rehabilitation of offenders. Research has consistently shown that rehabilitation programs for offenders, when they adhere to general principles of program design and delivery, will achieve significant reductions in recidivism. In this paper, we suggest that even greater reductions in recidivism can be achieved when readiness is addressed at the level of the individual offender, the program, and the context. A comprehensive understanding of readiness allows for fuller engagement in treatment, thus increasing probability of good treatment outcomes. We describe person, program, and context factors in a model of offender treatment readiness and discuss implications of the model for both assessment of offenders and for modification of low readiness.     

An antisymmetric psychometric function on a logarithmic scale

This very brief report introduces a psychometric function, very suitable for psychophysical data that displays Weber-like behaviour, because it is antisymmetric on a logarithmic scale.     

??Hier bin ich Mensch, hier darf ich??s sein!????Partaking in the Nanoworld

Images from the nanoworld are not at all disorienting or bewildering, as one might expect from contemplating the strange and surprising features that arise where classical physics comes to an end and quantum effects begin to appear. Instead, we see the traces of explorers in a world that appears to be infinitely malleable. The paper shows that the capability to visualize processes and phenomena at the nanoscale is a matter not only of research technologies and the advancement of observational techniques, but also a matter of developing a visual setting that exhibits knowledge and practice, surprise and control. The surface is such a stage and so is the landscape: they invite us to become immersed and move around like someone who goes for a walk. In order to appreciate this pictorial, as well as discursive, setting we turn to “strollology” as a method of reconstructing the world that is experienced in the manner of walking. With the notion of imagescape this method is applied to the modes of partaking in the nanoworld and its specific features. Rather than articulate theoretical or metaphysical presuppositions these nanoscapes serve to validate the very idea of nanotechnology.     

The influence of presession factors in the assessment of deviant arousal

Three adult male sex offenders with developmental disabilities participated in an evaluation of presession factors that may influence levels of sexual arousal measured with a penile plethysmograph. We evaluated the effects of presession masturbation (1 participant) and arousal-suppression strategies (2 participants). Results showed that presession masturbation lowered arousal levels and both participants suppressed arousal to varying degrees. These outcomes suggest the potential for consideration and manipulation of presession factors as treatment components for sex offenders with developmental disabilities.
