On authenticity: the question of truth in construction and autobiography

Freud was occupied with the question of truth and its verification throughout his work. He looked to archaeology for an evidence model to support his ideas on reconstruction. He also referred to literature regarding truth in reconstruction, where he saw shifts between historical fact and invention, and detected such swings in his own case histories. In his late work Freud pondered over the impossibility of truth in reconstruction by juxtaposing truth with ‘probability’. Developments on the role of fantasy and myth in reconstruction and contemporary debates over objectivity have increasingly highlighted the question of ‘truth’ in psychoanalysis. I will argue that ‘authenticity’ is a helpful concept in furthering the discussion over truth in reconstruction. Authenticity denotes that which is genuine, trustworthy and emotionally accurate in a reconstruction, as observed within the immediacy of the analyst/patient interaction. As authenticity signifies genuineness in a contemporary context its origins are verifiable through the analyst’s own observations of the analytic process itself. Therefore, authenticity is about the likelihood and approximation of historical truth rather than its certainty. In that respect it links with Freud’s musings over ‘probability’. Developments on writing ‘truths’ in autobiography mirror those in reconstruction, and lend corroborative support from another source.     

Biopsychosocial etiology of obsessions and compulsions: an integrated behavioral-genetic and cognitive-behavioral analysis

Accumulating evidence suggests that particular kinds of dysfunctional beliefs contribute to obsessive-compulsive (OC) symptoms. Three domains of beliefs have been identified: (a) perfectionism and intolerance of uncertainty, (b) overimportance of thoughts and the need to control thoughts, and (c) inflated responsibility and overestimation of threat. These beliefs and OC symptoms are both heritable. Although it is widely acknowledged that OC symptoms probably have a complex biopsychosocial etiology, to our knowledge there has been no previous attempt to integrate dysfunctional beliefs and genetic factors into a unified, empirically supported model. The present study was an initial step in that direction. A community sample of monozygotic and dizygotic twins (N = 307 pairs) completed measures of dysfunctional beliefs and OC symptoms. Structural equation modeling was used to compare 3 models: (a) the belief causation model, in which genetic and environmental factors influence beliefs and OC symptoms, and beliefs also influence symptoms; (b) the symptom causation model, which is the same as (a) except that symptoms cause beliefs; and (c) the belief coeffect model, in which beliefs and OC symptoms are the product of common genetic and environmental factors, and beliefs have no causal influence on symptoms. The belief causation model was the best fitting model. Beliefs accounted for a mean of 18% of phenotypic variance in OC symptoms. Genetic and environmental factors, respectively, accounted for an additional 36% and 47% of phenotypic variance. The results suggest that further biopsychosocial investigations may be fruitful for unraveling the etiology of obsessions and compulsions.     

The influence of heightened body‐awareness on walking through apertures

The reported study measured the ratio between aperture‐width and hip‐width that marked the critical transition from frontal walking to body rotation for male and female participants. Half of the participants of each sex wore form‐fitting lycra clothes and half loose‐fitting jogging suits. Participants wearing the form‐fitting clothing reported heightened body awareness relative to those wearing the loose‐fitting clothing. For male participants this difference was reflected in a smaller aperture‐to‐hip ratio in the form‐fitting than loose‐fitting clothing condition. That is, males walked frontally through smaller apertures when wearing form‐fitting than when wearing loose‐fitting clothing. For females there was no difference in walking action as a function of clothing style. Results are discussed in terms of the perception of action opportunities in the environment, the influence of body awareness on such perception and sex differences.

Self-informant Agreement for Personality and Evaluative Person Descriptors: Comparing Methods for Creating Informant Measures

Little attention typically is paid to the way self-report measures are translated for use in self-informant agreement studies. We studied two possible methods for creating informant measures: (a) the traditional method in which self-report items were translated from the first- to the third-person and (b) an alternative meta-perceptual method in which informants were directed to rate their perception of the targets' self-perception. We hypothesized that the latter method would yield stronger self-informant agreement for evaluative personality dimensions measured by indirect item markers. We studied these methods in a sample of 303 undergraduate friendship dyads. Results revealed mean-level differences between methods, similar self-informant agreement across methods, stronger agreement for Big Five dimensions than for evaluative dimensions, and incremental validity for meta-perceptual informant rating methods. Limited power reduced the interpretability of several sparse acquaintanceship effects. We conclude that traditional informant methods are appropriate for most personality traits, but meta-perceptual methods may be more appropriate when personality questionnaire items reflect indirect indicators of the trait being measured, which is particularly likely for evaluative traits.     

Team capability beliefs over time: Distinguishing between team potency,team outcome efficacy,and team process efficacy

Teams that have positive beliefs about their capability tend to perform more effectively. However, relatively little is known about the nature and change of different types of team capability beliefs. Team potency and team efficacy are two approaches to understanding team capability beliefs, but few studies have considered these beliefs simultaneously. We investigate their distinctiveness and relative predictive power. Additionally, we propose two types of team efficacy: team outcome efficacy and team process efficacy. In two longitudinal samples of executive MBA study teams (sample 1, N=213 individuals in 41 teams; sample 2, N=360 individuals in 89 teams), we showed that team potency, team outcome efficacy, and team process efficacy are factorially distinct and measure invariant at four time points over 7 months (except for high levels of team outcome efficacy for which factorial invariance emerged). We also show differential predictive validity. Team outcome efficacy was the strongest predictor of objective team performance, whereas team process efficacy was the best predictor of citizenship behaviours. Team potency predicted both outcomes, albeit more weakly. Collectively, the findings show the value of a more fine‐grained approach to teams' capability beliefs, including a new validated measure of team process efficacy.     

Differing effects of systemically administered rapamycin on consolidation and reconsolidation of context vs. cued fear memories

Rapamycin, an inhibitor of the mammalian target of rapamycin (mTOR) kinase, has attracted interest as a possible prophylactic for post-traumatic stress disorder (PTSD)-associated fear memories. We report here that although rapamycin (40 mg/kg, i.p.) disrupted the consolidation and reconsolidation of fear-potentiated startle paradigm to a shock-paired context, it did not disrupt startle increases to a 4-sec odor cue, even though post-training increases in amygdala mTOR activity were prevented by rapamycin (also 40 mg/kg, i.p.). Thus, while rapamycin may prove useful in retarding the development of some PTSD-associated memories, its relative ineffectiveness against cued fear memories may limit its clinical usefulness.     

Affording cooperation: Embodied constraints,dynamics, and action-scaled invariance in joint lifting

Understanding the physical and interpersonal constraints that afford cooperation during real-world tasks requires consideration of the fit between the environment and task-relevant dimensions of coactors and the coactors’ fit with each other. In the present study, we examined how cooperation can emerge during ongoing interaction using the simple task of two actors’ moving long wooden planks. The system dynamics showed hysteresis: A past-action mode persisted when both solo and joint actions were possible. Moreover, pairs whose arm spans were both short, both long, or mismatched made action-mode transitions at similar points, when scaled by a relational measure. The relational measure of plank length to arm span was dictated by the pair member with the shorter arm span, who, thus, had a greater need to cooperate during the task. The results suggest that understanding affordances for cooperation requires giving more consideration to constraints imposed by the fit between coactors’ action capabilities.     

Effects of context on eye movements when reading about possible and impossible events

Plausibility violations resulting in impossible scenarios lead to earlier and longer lasting eye movement disruption than violations resulting in highly unlikely scenarios (K. Rayner, T. Warren, B. J. Juhasz, & S. P. Liversedge, 2004; T. Warren & K. McConnell, 2007). This could reflect either differences in the timing of availability of different kinds of information (e.g., selectional restrictions, world knowledge, and context) or differences in their relative power to guide semantic interpretation. The authors investigated eye movements to possible and impossible events in real-world and fantasy contexts to determine when contextual information influences detection of impossibility cued by a semantic mismatch between a verb and an argument. Gaze durations on a target word were longer to impossible events independent of context. However, a measure of the time elapsed from first fixating the target word to moving past it showed disruption only in the real-world context. These results suggest that contextual information did not eliminate initial disruption but moderated it quickly thereafter.
