Repulsion or attraction? Group membership and assumed attitude similarity

Three studies investigated group membership effects on similarity-attraction and dissimilarity-repulsion. Membership in an in-group versus out-group was expected to create initially different levels of assumed attitude similarity. In 3 studies, ratings made after participants learned about the target's attitudes were compared with initial attraction based only on knowing target's group membership. Group membership was based on political affiliation in Study 1 and on sexual orientation in Study 2. Study 3 crossed political affiliation with target's obnoxiousness. Attitude dissimilarity produced stronger repulsion effects for in-group than for out-group members in all studies. Attitude similarity produced greater increments in attraction for political out-group members but not for targets with a stigmatic sexual orientation or personality characteristic.     

An experimental evaluation of tic suppression and the tic rebound effect

Tourette's syndrome (TS) is a neurobiological disorder consisting of motor and vocal tics that are thought to be temporarily suppressible. Many professionals, however, believe that a paradoxical increase in tic frequency (above baseline levels) occurs when efforts to suppress have ceased (i.e., a rebound effect). To date, little research has investigated tic suppression or its effects. This study examined tic frequency during baseline, suppression, and post-suppression conditions using an experimental preparation reported to reliably produce tic suppression in children. Six children with TS and one with chronic tic disorder (CTD) were recorded during baseline and repeated suppression and post-suppression conditions. Tic frequency was significantly lower during suppression as compared to baseline. Although tic frequency during post-suppression was higher than during suppression, it was lower than baseline levels, arguing against a "rebound" effect of tic suppression. Exploratory analyses revealed that scores on the attention problems subscale of the Child Behavior Checklist significantly predicted tic suppressibility. The relationships between age, tic severity, and tic suppressibility were also explored.     

Deflationism And The Truth Conditional Theory of Meaning

Controversy has arisen of late over the claim that deflationism about truth requires that we explain meaning in terms of something other than truth-conditions. This controversy, it is argued, is due to unclarity as to whether the basic deflationary claim that a sentence and a sentence that attributes truth to it are equivalent in meaning is intended to involve the truth-predicate of the object language for which we develop an account of meaning, or is intended to involve the truth-predicate of the metalanguage in which we develop an account of meaning. The former view is compatible with the truth-conditional theory of meaning for the object language, the latter is incompatible with it. However, the former view is also trivially true; hence we should endorse the claim that any form of deflationism worth being interested in is incompatible with understanding meaning truth-conditionally.     

Benchmarking Treatment Response in Tourette’s Disorder: A Psychometric Evaluation and Signal Detection Analysis of the Parent Tic Questionnaire

This study assessed the psychometric properties of a parent-reported tic severity measure, the Parent Tic Questionnaire (PTQ), and used the scale to establish guidelines for delineating clinically significant tic treatment response. Participants were 126 children ages 9 to 17 who participated in a randomized controlled trial of Comprehensive Behavioral Intervention for Tics (CBIT). Tic severity was assessed using the Yale Global Tic Severity Scale (YGTSS), Hopkins Motor/Vocal Tic Scale (HMVTS) and PTQ; positive treatment response was defined by a score of 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions – Improvement (CGI-I) scale. Cronbach’s alpha and intraclass correlations (ICC) assessed internal consistency and test-retest reliability, with correlations evaluating validity. Receiver- and Quality-Receiver Operating Characteristic analyses assessed the efficiency of percent and raw-reduction cutoffs associated with positive treatment response. The PTQ demonstrated good internal consistency (α = 0.80 to 0.86), excellent test-retest reliability (ICC = .84 to .89), good convergent validity with the YGTSS and HM/VTS, and good discriminant validity from hyperactive, obsessive-compulsive, and externalizing (i.e., aggression and rule-breaking) symptoms. A 55% reduction and 10-point decrease in PTQ Total score were optimal for defining positive treatment response. Findings help standardize tic assessment and provide clinicians with greater clarity in determining clinically meaningful tic symptom change during treatment.     

Cortisol and Children’s Adjustment: The Moderating Role of Sympathetic Nervous System Activity

We examined relations among cortisol, markers of sympathetic nervous system (SNS) activity (including salivary alpha-amylase and skin conductance level), and children's adjustment. We also tested the Bauer et al. (Journal of Developmental and Behavioral Pediatrics, 23(2), 102-113, 2002) hypothesis that interactions between the SNS and cortisol would be associated with internalizing and externalizing problems. Saliva samples were obtained from 8- to 9-year-olds before and after a laboratory assessment battery, and were assayed for cortisol and alpha-amylase (sAA). Basal skin conductance level (SCL) was measured during resting conditions. Parents reported on child adjustment. Interactions between basal SNS and cortisol levels explained moderate amounts of unique variance in children's externalizing and internalizing problems. More specifically, higher basal cortisol levels were positively associated with higher internalizing and externalizing problems among children with higher SNS activity, as compared to children with lower SNS activity. Findings underscore the utility of including information about the coordination between hypothalamic-pituitary-adrenal (HPA) and SNS activity in biosocial models of atypical child development.     

The impact of pretrauma analogue GAD and posttraumatic emotional reactivity following exposure to the September 11 terrorist attacks: a longitudinal study

The relation between analogue generalized anxiety disorder (GAD) assessed the day before the events of September 11, 2001 (9/11) and long-term outcome was examined in 44 young adults who were directly exposed the following day to the terrorist attacks in New York City. After controlling for high exposure to the attacks, preattack analogue GAD was associated with greater social and work disability, loss of psychosocial resources, anxiety and mood symptoms, and worry, but not symptoms of posttraumatic stress, assessed 12 months after 9/11. Fear and avoidance of emotions assessed 4 months after 9/11 statistically mediated the relation between preattack analogue GAD and social and work disability, loss of psychosocial support, mood and anxiety symptoms, and worry at 12-month follow-up. Avoidance of emotions 4 months after 9/11 also mediated the relation between preattack analogue GAD and posttraumatic stress symptoms 12 months after 9/11.     

The Relationship Between Dysfunctional Interpersonal Tendencies, Derailment Potential Behavior, and Turnover

Managerial derailment, which includes failure in the form organizational exit, poses costly consequences for organizations. We investigated the relationship between dysfunctional interpersonal tendencies, derailment potential behaviors, and actual managerial derailment in the form of voluntary and involuntary turnover. Data were from an archival database of high-level managers working for a global retail organization, including self-report interpersonal tendencies, 360-degree feedback data, and personnel history (N?=?1,796). Managers who exhibit the dysfunctional interpersonal tendencies associated with ??moving against people?? were more likely to enact derailment potential behaviors. As a result, these managers were more likely to be fired or quit. This study advances our understanding of the managerial derailment process by providing evidence of the positive relationship between derailment potential behaviors and both voluntary and involuntary turnover as well as the potential for ??moving against?? people to result in derailment. Our results may help to inform the selection, promotion, and training strategies employed by practitioners and potentially reduce the costs associated with losing high-potential executives. This is one of the first studies to provide evidence of the relationship between derailment potential behaviors and turnover, and in a rarely obtained sample of high-level managers. Additionally, derailment potential ratings were collected before managers?? exit from the organization, thus helping to overcome retrospective bias evident in prior studies; managers who ultimately derail were perceived as having exhibited behaviors consistent with the potential to derail before organizational exit.     

The six most essential questions in psychiatric diagnosis: A pluralogue part 2: Issues of conservatism and pragmatism in psychiatric diagnosis

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM ?C whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.     

Shape effects on memory for location

The participants were 40 students who were briefly presented 32 dot locations, one at a time, and attempted to reproduce each location after a short delay. Half of the participants completed the task with the surrounding shapes being a circle, a horizontal ellipse, and a vertical ellipse; for the other half, the surrounding shapes were a square, a triangle, and a pentagon. Elongation of the task field along an axis led to exaggerated bias along that axis, but the pattern of bias was fairly constant across the shapes. The data were modeled by assuming that bias in estimation was due to the weighting of spatial category prototypes. Modeling indicated that shape affected spacing of prototypes, but there was no evidence that it affected the number of prototypes. These results were consistent with use of a viewer-based frame of reference, with prototypes reflecting four spatial quadrants generated by left—right and up—down distinctions from the viewer’s perspective.
