Die Therapeutenvariable

Background

The objective of this study was to investigate the therapeutic attitude as a self-contained dimension of the therapeutic process.

Patients and methods

The psychotherapists’ beliefs and attitudes in therapeutic matters are measured according to the Therapeutic Attitude Scales (TASC) of the Therapeutic Attitude Questionnaire (ThAt) and were applied to investigate the therapist variable. The investigation concentrated on the therapist’s belief in the curative value of a number of ingredients of psychotherapy, on the therapist’s individual style of conducting psychotherapy and on basic assumptions about the nature of psychotherapy and the nature of the human mind. A total of 451 psychotherapists (81 psychodynamic psychotherapists, 208 psychoanalytic psychotherapists and 162 behaviour therapists) were investigated.

Results

There were highly significant differences between the three groups of therapists, a finding which is in line with the basic theory. Adaptation and insight of the assumed curative factors as well as supportiveness and neutrality of the technique factors, differentiate the groups highly significantly. The multivariate analysis underlines the importance of adaptation and insight to differentiate between all groups.

Conclusion

The results by and large confirm the general assumptions held on the differences between the groups. Thus the ThAt appears to be a valid instrument to grasp more subtle features of the therapist variable that may influence the outcome of psychotherapy.     

Does attention impair temporal discrimination? Examining non-attentional accounts

Recently, Yeshurun and Levy (Psychol Sci 14:225-231, 2003) have provided evidence for the notion that visual attention impairs the temporal resolution of the visual system. Specifically, the detection of a temporal gap within a visual stimulus was impaired when a cue directed attention towards the spatial location of the stimulus. As this negative cueing effect is important to constrain theories about visual attention, we further investigated this novel effect and assessed whether it truly reflects an attentional effect. Experiment 1 examines whether the negative cueing effect is due to local temporal interference, and Experiments 2 and 3 investigate whether it reflects a luminance confound. The complete pattern of results argues against these alternatives and thus further strengthens the conclusion of Yeshurun and Levy (Psychol Sci 14: 225-231, 2003).     

Reciprocal Relationships Between Parenting Behavior and Disruptive Psychopathology from Childhood Through Adolescence

Theoretical models suggest that child behaviors influence parenting behaviors, and specifically that unpleasant child behaviors coerce parents to discontinue engaging in appropriate discipline. This study examined reciprocal relationships between parenting behaviors (supervision, communication, involvement, timid discipline and harsh punishment) and child disruptive disorder symptoms (ADHD, ODD and CD) in a clinic-referred sample of 177 boys. Annual measures, including structured clinical interviews, were obtained from the beginning of the study (when boys were between the ages of 7 to 12) to age 17. Specific reciprocal influence was observed; only timid discipline predicted worsening behavior, namely ODD symptoms, and ODD symptoms predicted increases in timid discipline. Greater influence from child behaviors to parenting practices was found: ODD also predicted poorer communication and decreased involvement, and CD predicted poorer supervision. ADHD was neither predictive of, nor predicted by, parenting behaviors. The results are specifically supportive of a coercive process between child behaviors and parenting behaviors, and generally suggestive of greater influence of child behaviors on parenting behaviors than of parenting behaviors on child behaviors.     

The perception of limb orientation depends on the center of mass

Three experiments were conducted to test the hypothesis that the perception of limb orientation depends on inertial eigenvectors against the alternative that it depends on the center of mass. In all experiments, each participant pointed at visible targets with his or her occluded right arm while center-of-mass and inertial eigenvectors were manipulated independently. In Experiments 1 and 2, the arm was constrained to rotate exclusively about the shoulder, whereas in Experiment 3, the arm was allowed to rotate freely about both the shoulder and the elbow. The mechanical manipulations were applied either in the horizontal (Experiments 1 and 3) or vertical (Experiment 2) plane. Across experiments, pointing direction was affected by the center of mass and not by the inertial eigenvectors, albeit that simultaneous manipulation of both resulted in a more pronounced pointing bias than the isolated center-of-mass manipulation. These findings challenge the inertial eigenvector hypothesis and suggest that the center of mass plays a generic role in the perception of limb orientation.     

Sequential effects within a short foreperiod context: evidence for the conditioning account of temporal preparation

Responses to an imperative stimulus (IS) are especially fast when they are preceded by a warning signal (WS). When the interval between WS and IS (the foreperiod, FP) is variable, reaction time (RT) is not only influenced by the current FP but also by the FP of the preceding trial. These sequential effects have recently been proposed to originate from a trace conditioning process, in which the individuals learn the temporal WS-IS relationship in a trial-by-trial manner. Research has shown that trace conditioning is maximal when the temporal interval between the conditioned and unconditioned stimulus is between 0.25 and 0.60 s. Consequently, one would predict that sequential effects occur especially within short FP contexts. However, this prediction is contradicted by Karlin [Karlin, L. (1959). Reaction time as a function of foreperiod duration and variability. Journal of Experimental Psychology, 58, 185-191] who did not observe the typical sequential effects with short FPs. To investigate temporal preparation for short FPs, three experiments were conducted, examining the sequential FP effect comparably for short and long FP-sets (Experiment 1), assessing the influence of catch trials (Experiment 2) and the case of a very dense FP-range (Experiment 3) on sequential FP effects. The results provide strong evidence for sequential effects within a short FP context and thus support the trace conditioning account of temporal preparation.     

Temporal preparation improves temporal resolution: Evidence from constant foreperiods

Recent research shows that temporal preparation within a constant foreperiod design improves the spatial resolution of visual perception. The present experiments were designed to investigate whether similar benefits of temporal preparation can be observed in a task that requires high temporal resolution. In three experiments, we assessed the effect of temporal preparation on temporal order judgments (TOJs). In Experiment 1, short foreperiods facilitated TOJ for two spatially adjacent dots. This finding was replicated in Experiment 2, in which the temporal order of two spatially overlapping stimuli (“+” and “x”) had to be discriminated. Experiment 3 investigated the time course of temporal preparation by extending these findings to a wide range of different foreperiod durations. The present findings corroborate recent evidence for a perceptual locus of temporal preparation. Most importantly, they show that temporal preparation within a constant foreperiod design improves the temporal resolution of visual perception, independently of whether TOJ requires a decision about the location or about the identity of the target stimuli.     

Response grouping in the psychological refractory period (PRP) paradigm: models and contamination effects

Response grouping is a ubiquitous phenomenon in psychological refractory period (PRP) tasks, yet it hampers the analysis of dual-task performance. To account for response grouping, we developed several extended versions of the standard bottleneck model, each of which incorporates a possible grouping mechanism into this model. Computer simulations were used to assess how the predictions of the standard model would change with each grouping mechanism. One set of simulations investigated the basic effects of grouping on the means and intercorrelation of the reaction times in the two tasks, as well as the percentage of trials with short interresponse times (IRTs). A second set of simulations examined whether response grouping would invalidate the use of PRP paradigms for localizing experimental effects. Finally, we investigated whether the post-hoc elimination of trials with short IRTs removes the contaminating effects of response grouping.     

A decidable multi-modal logic of context

We give a logic for formulas φ−ψ, with the informal reading “ψ is true in the context described by φ”. These are interpreted as binary modalities, by quantification over an enumerable set of unary modalities c−ψ, meaning “ψ is true in context c”. The logic allows arbitrary nesting of contexts.A corresponding axiomatic presentation is given, and proven to be decidable, sound, and complete.Previously, quantificational logic of context restricted the nesting of contexts, and was only known to be decidable in very special cases.     

Innovative Retention Methods in Longitudinal Research: A Case Study of the Developmental Trends Study

Minimizing participant attrition is vital to the success of longitudinal research. The Developmental Trends Study (DTS), a longitudinal study of the development of disruptive behavior disorders, has achieved a low attrition rate throughout the study. The development of early retention strategies, managing contact and scheduling history through the use of electronic databases, interviewer persistence, and the emergence of new electronic search methods have contributed to the success of our study. A literature review of retention methodology and practical solutions to maintain participant cooperation is described. A case study of the DTS is presented to inform researchers in longitudinal research on new methods used to maintain high retention rates.     

Girls’ Disruptive Behavior and its Relationship to Family Functioning: A Review

Although a number of reviews of gender differences in disruptive behavior and parental socialization exist, we extend this literature by addressing the question of differential development among girls and by placing both disruptive behavior and parenting behavior in a developmental framework. Clarifying the heterogeneity of development in girls is important for developing and optimizing gender-specific prevention and treatment programs. In the current review, we describe the unique aspects of the development of disruptive behavior in girls and explore how the gender-specific development of disruptive behavior can be explained by family linked risk and protective processes. Based on this review, we formulate a gender-specific reciprocal model of the influence of social factors on the development of disruptive behavior in girls in order to steer further research and better inform prevention and treatment programs.
