Cognitive processes in implicit attitude tasks: An experimental validation of the Trip Model

Implicit attitude tasks have become very popular in various areas of psychology. However, little is known about the cognitive processes they involve. To address this issue, we investigated the underlying processes of the Go/No‐go Association Task (GNAT), a go/no‐go variant of the well‐known Implicit Association Test (IAT). More precisely, we tested two alternative multinomial processing tree (MPT) models of GNAT performance, the Trip Model and the generalized Quad Model. Both models assume that GNAT performance is influenced not only by automatic associations but also by response biases and a controlled discrimination process. However, the two models differ with respect to an additional overcoming bias process. In contrast to the Quad Model, the Trip Model assumes that overcoming bias does not play a major role in GNAT performance. Instead, the Trip Model emphasizes the role of response biases. We report three experiments that demonstrate the validity of the Trip Model for GNAT data. Copyright © 2010 John Wiley & Sons, Ltd.     

Does personality disorder co-morbidity impact treatment outcome for patients with major depression? A multi-level analysis

In literature, there exists disagreement regarding the impact of comorbid personality disorder(s) (PD[s]) on treatment outcome for patients with major depressive disorder (MDD). The aim of this paper was to investigate whether statistical heterogeneity and inter-dependency are potential moderators of the effect of co-morbid PDs on outcome for patients with MDD. Clinician-rated MADRS scores and DSM-IV Axis II personality disorder diagnoses were obtained from 562 outpatients with MDD who received 6 months of combined psycho- and pharmacotherapy. Single-level regression showed significantly worse treatment outcome among patients with co-morbid PD, as compared to patients with no PD. After controlling for statistical heterogeneity and interdependency, treatment outcome was no longer significantly worse for patients with co-morbid PD. In conclusion, heteroscedasticity and inter-dependency should be considered as potentially compelling explanations for inconsistencies in findings on treatment outcome for depressed patients with co-morbid PDs.     

The Illness/Injury Sensitivity Index: Validation of a German Version of the ISI-R

Three fundamental fears-anxiety sensitivity, fear of negative evaluation, and illness/injury sensitivity-are considered integral components of anxiety-related psychopathology and also bear connections with chronic pain. Scales measuring the first two fears, the Anxiety Sensitivity Index and the Fear of Negative Evaluation Scale, have been translated into German; however, the nine-item Illness/Injury Sensitivity Index-Revised (ISI-R) that measures fears of injury and illness has not been available in German language yet. The aim of this study therefore was a translation of the ISI-R into German language and an initial validation of the translated scale in two different samples. The German ISI-R was translated by both professionals and laypersons, and a final version was decided on by consensus. In Study 1, participants included 96 undergraduate students (85% women) who completed the German version of the ISI as part of a larger study. An exploratory factor analysis with oblique rotation was conducted and suggested a two-factor-solution with one factor representing fears of illness and the other fears of injury. This factor structure was confirmed via a confirmatory factor analysis (CFA) in Study 2. Participants included 117 community members (79% women). Convergent validity was supported using a visual analogue scale for fear of illness in both samples and the German translation of the Whiteley Index in Study. Overall, the results supported the German translation of the ISI-R. Comprehensive results, limitations, and directions for future research are discussed.     

Language, moral order and political praxis

The paper argues that the debate between objectivist criticism and postmodern critique represents a fracturing of the modes of mundane social and linguistic practice. The two together miss the open-textured character of language-in-use and the reflexive properties of situated human practice. Both difference and agreement are grounded in the multiplicity of criteria that are a feature of the logical grammar of language, and therefore of everyday praxis, including that of critique. To escape the duality of foundationalism on the one hand, and radical relativism on the other, attention to the praxiological details of human action and reasoning is needed. The paper draws on Wittgensteinian philosophy and ethnomethodological studies of reasoning to make its case.     

Words may not be enough! No increased emotional Stroop effect in obsessive-compulsive disorder

Conflicting evidence has been obtained whether or not patients diagnosed with obsessive-compulsive disorder (OCD) share an attentional bias towards disorder-related stimuli. Some of these inconsistencies can be accounted for by suboptimal stimuli selection. In consideration of the heterogeneity of OCD, we investigated Stroop interference effects for two classes of OCD items (i.e., washing and checking) in 23 OCD patients and 23 healthy controls. In order to cover prevalent OCD concerns, item compilation was based on experts' appraisals. Patients neither displayed greater immediate as well as delayed Stroop interference nor any bias for OCD and subtype-congruent stimuli. On the contrary, for washing-related items, OCD patients, and here especially washers, displayed facilitation relative to healthy controls. Although the present study at first sight refutes the notion of an attentional bias in OCD in contrast to other anxiety disorders, several potential moderators need to be considered before this account is ultimately dismissed. In particular, an attentional bias may only be elicited using visual material that is more attention-grabbing than verbal stimuli. Finally, blockwise instead of random item administration and greater consideration of individual relevance may be crucial prerequisites for the effect to emerge.     

Personality disorders and pathological gambling: a review and re-examination of prevalence rates

The current study reviews and reexamines the association between pathological gambling and personality disorders (PDs). To date, the majority of investigations have examined the prevalence of PDs in a single group of treatment-seeking pathological gamblers (PGs); very few of these studies included a comparison group, and even fewer compared PGs to nonpathological gamblers who, in contrast to nongamblers, resemble PGs in their attraction to and engagement in gambling behavior. The current study included a sample composed of nontreatment-seeking pathological gamblers and a comparison group of nonpathological gamblers (NPGs); these participants completed a self-report instrument (SCID-II/PQ) and were administered a structured clinical interview SCID-II) designed to assess PDs. Compared to the SCID-II, the SCIDII/PQ produced significantly higher PD prevalence rate estimates and symptom endorsements. Although the pattern of specific PD prevalence and symptom endorsement varied somewhat across the instruments, PGs consistently displayed significantly higher levels of borderline PD than NPGs; this pattern endured even after controlling for Axis I disorders and overlap among Axis II PDs.     

No evidence for object alternation impairment in obsessive-compulsive disorder (OCD)

Recent neuroimaging studies have consistently ascribed the orbito-frontal cortex (OFC) a pivotal role in the pathogenesis of obsessive-compulsive disorder (OCD). Cognitive tests presumed sensitive to this region, such as the Object Alternation Task (OAT), are considered important tools to verify this assumption and to investigate the impact of cortical dysfunction on behavior. The aim of the present study was to assess if patients with OCD show enhanced perseveration errors on the OAT relative to healthy controls taking into account several potential moderators, especially comorbid depression and OCD subtype. Thirty-five OCD patients and 18 healthy controls underwent the OAT as well as the Trail-Making Tests (TMT) A and B. In line with prior studies, OCD patients were slowed on both TMT tasks. In contrast, samples performed similarly on the OAT. While the latter finding does not invalidate the assumption that the OFC is affected in OCD, dysfunctions involving this region may be more subtle than often claimed and likely encompass only a small subset of functional domains hosted in the OFC.     

Working with and ‘seeing through’ the sexual transference in the psychotherapy of an adolescent boy

This paper explores the challenges and developmental opportunities of working with the sexual transference in psychotherapy with adolescents. Psychoanalytic contributions investigating the nature of adolescent sexuality and the developmental move from a narcissistic organisation to a capacity to form intimate relationships are reviewed, and the question of what happens when there is a lack of containment in infancy is addressed. The way in which unintegrated sexual impulses and phantasies can invade the therapeutic relationship is further discussed through the account of the weekly psychotherapy of a 16-year-old boy who formed a powerful sexual transference to his female therapist. The paper highlights how working through the sexual transference enabled this young man to face his developmental paralysis and begin to use the therapy as an opportunity for psychic growth.
