Do positive illusions predict overconfidence in judgment? A test using interval production and probability evaluation measures of miscalibration

We address the question as to whether judgmental overconfidence, as assessed by probability miscalibration, is related to positive illusions about the self. We first demonstrate that judgmental overconfidence measured with interval production procedures can be considered a trait, due to correlations observed in miscalibration scores in two sets of general‐knowledge questions of varying difficulty administered at different times. In addition, the hard‐easy effect operated in different ways on overprecision and self‐placement of one's performance relative to others: The more difficult the calibration task, the greater the over precision but the greater the under placement of one's performance. Finally, there was no evidence that miscalibration was related to dispositional optimism and self‐efficacy. A second study extended these results by including further measures of disposition to experience positive illusions such as unrealistic optimism, a general tendency to consider oneself “better‐than‐average,” and two indexes of dispositional perception of control. The positive illusion measures showed considerable inter‐correlations, but did not correlate with miscalibration on the interval production task, and correlated negatively with optimism concerning societal risks. A final study replicated this pattern of findings, but showed that disposition to positive illusions did predict miscalibration on the same questions measured with a probability evaluation technique. Our research demonstrates that “overconfidence” is not a unitary construct, but a series of overlapping ones. Copyright © 2010 John Wiley & Sons, Ltd.     

On the role of visual afferent information for the control of aiming movements toward targets of different sizes

The authors investigated (a). whether the specificity of practice hypothesis is mediated by the importance of visual afferent information for the control of manual aiming movements and (b). how movement planning and online correction processes to the movement initial impulse are affected by the withdrawal of visual information in transfer. In acquisition, participants (N = 40) aimed at targets of different sizes in a full-vision or in a target-only condition before being transferred to a target-only condition without knowledge of results. The results supported the hypothesis that learning is specific to the source or sources of afferent information that are more likely to ensure optimal performance. The results also suggested that individuals will not always use visual afferent information more extensively when aiming at a small rather than at a large target. Instead, in a temporally constrained task, the relative efficiency of visually based corrections appears to mediate how exclusively an individual will rely on online visual afferent information for movement control. Finally, the detailed kinematic analysis performed in the present study clearly indicated that online modifications to the movement primary impulse are possible, arguing for a continuous or pseudo-continuous control of relatively slow aiming movements on the basis of visual afferent input.     

Elaboration et validation de tests de jugement situationnel comme outil de sélection professionnelle : guide méthodologique

Current views in personnel selection recognize the necessity for situational judgements tests (SJT) which are closed to the real work context of companies. The SJTs have also become a popular selection tool across Europe. SJTs are attractive because they show good validity, positive applicants reactions and can be cost effective to test large group of applicants at once. The aim of this paper is to describe a structured methodology for the elaboration of such test. Each stage is illustrated by examples and psychometrics validation issues are discussed.     

Validity of the Personality Assessment Inventory Aggression scales and Violence Potential index in veterans with PTSD

In this study, we examined the validity of the Personality Assessment Inventory (PAI; Morey, 1991) Aggression (AGG) scales and Violence Potential index (VPI) in 399 male combat veterans presenting for formal evaluation of posttraumatic stress disorder (PTSD). The AGG scales exhibited convergence with other measures of hostility and violence and demonstrated discriminant validity with alternative constructs. When we examined reports of interpersonal violence in the past year, the AGG composite scale displayed substantial incremental validity over the effects of PTSD severity, demographics, a simple dichotomous question regarding violence in the past 30 days, and MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scales measuring aggression. The VPI, however, added no unique explanatory power over the AGG composite scale.     

Electrophysiological evidence of different loci for case-mixing and word frequency effects in visual word recognition

Do word frequency and case mixing affect different processing stages in visual word recognition? Some studies of online reading have suggested that word frequency affects an earlier, perceptual-encoding stage and that case mixing affects a later, central decision stage (e.g., Reingold, Yang, & Rayner, Journal of Experimental Psychology: Human Perception and Performance 36:1677-1683 2010); others have suggested otherwise (e.g., Allen, Smith, Lien, Grabbe, & Murphy, Journal of Experimental Psychology: Human Perception and Performance 31:713-721 2005; Besner & McCann, 1987). To determine the locus of the word frequency and case-mixing effects, we manipulated word frequency (high vs. low) and case type (consistent lower case vs. mixing case) in a lexical-decision paradigm. We measured two event-related-potential components: the N170 (an early peak occurring 140-240 ms after stimulus onset, related to structural encoding) and the P3 (a late peak occurring 400-600 ms after stimulus onset, related to stimulus categorization). The critical finding was that the N170 amplitude was sensitive to case mixing, but the P3 amplitude was sensitive to word frequency and lexicality. These results suggest that case mixing affects an earlier processing stage than does word frequency, at least with respect to lexical-decision processes.     

L’évaluation de la formation à l’harmonisation travail-vie personnelle : bilan et perspectives de recherche

The present article offers a review of the literature evaluating work-life balance training (which includes work-family balance training). The research, spanning over 43 databases, allowed the identification of 17 pertinent peer-reviewed articles. The selected studies are analysed in light of their main characteristics (design, sample, intervention, outcomes, etc.). The analysis shows that the offering of work-life balance training benefits both employees and managers. The methodological presuppositions and limitations of the selected studies are then critically examined. Lastly, possible topics for further research, such as the importance of conducting comparative researches and of adopting quasi-experimental and experimental protocols, are suggested in manner of conclusion.     

The effects of a responsive parenting intervention on parent-child interactions during shared book reading

This study examined mother-child shared book reading behaviors before and after participation in a random-assignment responsive parenting intervention called Play and Learning Strategies (PALS) that occurred during infancy (PALS I), the toddler-preschool (PALS II) period, or both as compared with a developmental assessment (DAS) intervention (DAS I and/or II). The efficacy of PALS was previously demonstrated for improving mother and child behaviors within play contexts, everyday activities, and standardized measures of child language. We hypothesized that PALS effects would generalize to influence maternal and child behaviors during a shared reading task even though this situation was not a specific focus of the intervention and that this would be similar for children who varied in biological risk. Participation in at least PALS II was expected to have a positive effect due to children's increased capacity to engage in book reading at this age. Four groups of randomized mothers and their children (PALS I-II, PALS I-DAS II, DAS I-PALS II, DAS I-II) were observed in shared reading interactions during the toddler-preschool period and coded for (a) mother's affective and cognitive-linguistic supports and (b) child's responses to maternal requests and initiations. Support was found for significant changes in observed maternal and child behaviors, and evidence of mediation was found for the intervention to affect children's behaviors through change in maternal responsiveness behaviors. These results add to other studies supporting the importance of targeting a broad range of responsive behaviors across theoretical frameworks in interventions to facilitate children's development.
