Development and Validation of the False Disorder Score: The Focal Scale of the Inventory of Problems

Abstract

This article introduces the Inventory of Problems (IOP)—a new, computerized, 181-item tool designed to discriminate bona fide from feigned mental illness and cognitive impairment—and presents the development and validation of its focal, feigning scale, the False Disorder Score (IOP–FDS). The initial sample included (a) 211 patients and 64 offenders who took the IOP under standard conditions, and (b) 210 community volunteers and 64 offenders who feigned mental illness. We split this sample into three subsamples. The first (n?=?301) was used to select the variables to generate the IOP–FDS; the second (n?=?148) scaled the IOP–FDS into a probability score; and the third (n?=?100) tested its validity with an independent data set. In this third subsample, the IOP–FDS had sensitivity?=?.90, specificity?=?.80, and a greater area under the curve (AUC?=?.95) than the IOP–29 (.91). For 40 participants, the Personality Assessment Inventory (PAI) was available, too. Within this subgroup, the IOP–FDS outperformed the selected PAI validity scales (AUC?=?.99 vs. AUC ≤ .85).     

On the automatic evaluation of social exemplars

The present article focuses on the automatic evaluation of exemplars whose category membership has been learned in the past. Studies 1 and 2 confirmed the hypothesis that once an exemplar has been encoded as a member of a given group, at a later encounter the evaluation associated with the group will be unintentionally retrieved from memory, even when no perceptual cue indicates the exemplar's category membership. Study 3 extended the results to the domain of in-group/out-group differentiation. In addition. Studies 4 and 5 confirmed the hypothesis that stored evaluations can be retrieved and affect responses even when the semantic information on which the evaluations were originally based is no longer available for retrieval. Finally, Study 6 investigated spontaneous approach-avoidance behavior tendencies. Overall, results demonstrate the pervasive effects of person-based representations, and they are discussed in terms of recent models of person perception and out-group discrimination.     

Two-, three-, and four-factor PCL-R models in applied sex offender risk assessments

The authors compared 2-, 3-, 4-factor, and 2-factor/4-facet Psychopathy Checklist-Revised (PCL-R) models in a previously unpublished sample of 1,566 adult male sex offenders assessed under applied clinical conditions as part of a comprehensive state-mandated community notification risk assessment procedure. "Testlets" significantly improved the performance of all models. The 3-factor model provided the best fit to the current data, followed by the 2-factor/4-facet model. The 2-factor model was not supported.     

Self-serving biases: The role of perspective-taking

This research explores the role of perspective taking in self-serving biases. Assisted by a confederate, 80 subjects performed an impression-formation task and were given either success or failure bogus feedback. One week later, half of the subjects watched their performance on videotape and provided causal attributions (‘observers’). The other half simply gave causal attributions (‘actors’). Thus, the experiment employed a modified version of the actor/observer paradigm with one group of subjects taking the perspective of observers (‘observers’) and one group of subjects keeping their original perspective (‘actors’). The aim of this study was to test whether the change of perspective would increase dispositional causal attributions both in success and failure conditions. Results showed that subjects gave greater causal weight to internal factors (ability, effort) and less causal weight to external factors (task characteristics, collaboration with the partner) in the success than in the failure condition. Moreover, in a direct comparison task, subjects attributed a greater percentage of responsibility to themselves than to their partner in the success than in the failure condition. However, the type of perspective produced no significant effects, but showed an attenuation of self-serving biases for observers as compared to actors. A motivational explanation of the results is proposed.     

Handedness and hemispheric asymmetry of pattern reversal visual-evoked potentials

Pattern reversal visual-evoked potentials (EP) from temporal leads in the two hemispheres of 26 right-handed (14 right-eye-dominant and 12 left-eye-dominant) and 10 left-handed (left-eye-dominant) adults were recorded. Checkerboard patterns (check sizes: 5.7 and 17 min of arc) at 1 and 8 Hz were reversed. Stimuli (a) subtended 6 degrees of visual field, (b) subtended 1 degree of visual field (foveal condition), and (c) were restricted to the annular portion of the visual field around the fovea (peripheral condition). Larger EP amplitudes in right or left hemisphere in relation to handedness, temporal frequency, and visual field condition were recorded. Eye dominance of dextrals appeared to play a role in determining the hemispheric asymmetry. Previous literature data and present results in relation to the hypothesis of different hemispheric specialization for basic visual information are discussed.     

60 Years of Practice,Research, and Teaching in Family Psychology and Family Therapy

Recent theoretical and empirical evidence as well as experimental and practical highlights from 60 years of clinical practice, research, and teaching in family therapy are summarized. This summary contains recent highlights that remain in my memory more vividly than others. I shall start with selected models of Relational Competence Theory (RCT), including variations on the theme of the Deadly Drama Triangle and their workbook applications.     

Emotional Valence and Perceived Event Frequency Affect Memory Accuracy for a Personally Relevant Life Event

False autobiographical remembering is known to be affected both by an event's emotional valence and its perceived frequency (PEF). Here, we present a procedure that enables the assessment of retrieval accuracy for details of an overarching personally relevant real‐life event (a graduation ceremony) while taking into account variations in both their valence and PEF. Former university students who attended the same graduation ceremony completed a questionnaire with true and false statements about the ceremony. Their task was to judge whether the event details were true. Event details were previously rated for valence (positive vs. negative) and PEF (high vs. low) and their truth status was confirmed with original video footage from the ceremony. The results showed that valence modulated the effect of PEF on memory accuracy in that a decrease in false memory judgements was observed only for negative low‐PEF (implausible) event details. These results are interpreted within the affect‐as‐information framework. Copyright © 2016 John Wiley & Sons, Ltd.     

Perceiving ingroup members who use stereotypes: implicit conformity and similarity

Previous studies have shown that people subtly conform more to ingroup members who use stereotype‐consistent rather than stereotype‐inconsistent information when describing an outgroup member (Castelli, Vanzetto, Sherman, & Arcuri, 2001 ). In the present article, we will address two important issues. First, we will examine whether this subtle conformity toward stereotypers is related to individuals' prejudice level (Study 1). Second, we will examine one of the processes that underlie the perception of ingroup members who use stereotype‐consistent information, hypothesizing that individuals implicitly feel more similar to such sources than to ingroup members who use stereotype‐inconsistent information (Study 2). Both hypotheses were confirmed and results are discussed in terms of the distinction between implicit and explicit attitudes and their implications in the maintenance of social stereotypes.
