Postidentification feedback effects on face recognition confidence: evidence for metacognitive influences

Information given to witnesses after an identification decision greatly alters their impressions of the original event and importantly, their identification confidence. Two experiments investigated the possibility that the effect of feedback on confidence may be altered according to the strength of the witness's cues to accuracy. Experiment 1 used a manipulation of exposure duration to alter recognition accuracy prior to the delivery of confirming, disconfirming or no feedback. While the feedback effect was not different across exposure duration conditions, decisions that were made more quickly were less likely to show large changes in confidence due to feedback. Experiment 2 manipulated the distinctiveness of faces and showed that the effects of feedback on confidence, and on the resolution of the confidence judgement, were more pronounced when disconfirming feedback was given for distinctive faces and when confirming feedback was given for typical faces. These studies showed that the impressions that participants formed of their likely accuracy might moderate the effects of feedback on decision confidence.

THE DIFFERENT FACETS OF MINDFULNESS

This afterword considers both the commonalities and differences in the approaches to mindfulness described in these two special journal issues. The approaches can be divided into those derived from scientific analysis and those taking a more experiential-humanistic perspective. These two perspectives generate different therapeutic strategies, which appear to have the same underlying principle. The question of whether practitioners should have a personal mindfulness practice is then considered. It is suggested that mindfulness is a holistic intervention. Finally, there are some personal reflections on running mindfulness courses.     

Negative Psychological Effects of Selection Methods: Construct Formulation and an Empirical Investigation into an Assessment Center

This paper defines and formulates the construct of negative psychological effects (NPEs) of selection and assessment methods upon applicants. The results of an empirical study into NPEs in an operational assessment center are also reported. Applicants (n=107) completed measures at three timepoints: Time 1 (just before the AC), Time 2 (immediately after the AC but before outcome decisions were known), and Time 3 (6 months after the AC). Both accepted and rejected candidates completed all three measures, which included self‐esteem, mental health, positive and negative affect, and career exploration behavior. No evidence of NPEs was found for rejected candidates despite significant between‐group differences on feedback reactions level items. Interestingly, well‐being and positive affect declined slightly for successful candidates at subsequent measurement compared against baseline Time 1 norms. Reactions level outcomes did, however, differ significantly between accepted and rejected candidates, with the latter rating feedback dimensions far less favorably. These results are discussed in relation to future research into the psychological impact of selection procedures upon candidates and the need for applied psychologists and HR practitioners to demonstrate that assessment methods do not exhibit NPEs upon applicants.     

Measures of sensitivity based on a single hit rate and false alarm rate: The accuracy, precision, and robustness of′,A z, andA’

Signal detection theory offers several indexes of sensitivity (d’,A _z, andA’) that are appropriate for two-choice discrimination when data consist of one hit rate and one false alarm rate per condition. These measures require simplifying assumptions about how target and lure evidence is distributed. We examine three statistical properties of these indexes: accuracy (good agreement between the parameter and the sampling distribution mean), precision (small variance of the sampling distribution), and robustness (small influence of violated assumptions on accuracy). We draw several conclusions from the results. First, a variety of parameters (sample size, degree of discriminability, and magnitude of hits and false alarms) influence statistical bias in these indexes. Comparing conditions that differ in these parameters entails discrepancies that can be reduced by increasing N. Second, unequal variance of the evidence distributions produces significant bias that cannot be reduced by increasing N—a serious drawback to the use of these sensitivity indexes when variance is unknown. Finally, their relative statistical performances suggest thatA _z is preferable toA’.

On Tarski’s Axiomatization of Mereology

Studia Logica - It is shown how Tarski’s 1929 axiomatization of mereology secures the reflexivity of the ‘part of’ relation. This is done with a fusion-abstraction principle that...     

Translating Logical Terms

The is an old question over whether there is a substantial disagreement between advocates of different logics, as they simply attach different meanings to the crucial logical terminology. The purpose of this article is to revisit this old question in light a pluralism/relativism that regards the various logics as equally legitimate, in their own contexts. We thereby address the vexed notion of translation, as it occurs between mathematical theories. We articulate and defend a thesis that the notion of “same meaning” is itself context-sensitive, depending on the purposes of a given conversation.

     

Let’s Play: Using Systemic and Experiential Techniques in the Play Therapy Instruction of MFT Masters’ Students

Marriage and family therapists are uniquely poised to work with entire families, including children. It is surprising then, that so few MFTs affiliate with play therapy. Many COAMFTE accredited masters’ programs offer some form of play therapy training, but therapists often report feeling uncomfortable with play therapy (Gil, 2015). In this paper, we offer a condensed refresher course on play therapy for MFTs, including suggested readings, materials, and instructions to expand training from a 2-day seminar to a 14-week course. We discuss the strengths and weaknesses of offering play therapy instruction as a semester long required course for masters’ students.     

What Drives OCD Symptom Change During CBT Treatment? Temporal Relationships Among Obsessions and Compulsions

Cognitive behavior therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD). However, less is known about how obsessions and compulsions change during treatment, either in tandem, sequentially, or independently. The current study used latent difference score analysis to show path-analytic dynamic modeling of OCD symptom change during CBT. Four competing models of the temporal relationship between obsessions and compulsions were examined: no coupling (obsessions and compulsions are not dynamically related), goal directed (obsessions lead to subsequent changes in compulsions), habit driven (compulsions lead to subsequent changes in obsessions), and reciprocal. Treatment seeking participants (N = 84) with a principal diagnosis of OCD completed 12 weeks of CBT group therapy and completed measures assessing obsession and compulsion severity at pretreatment, Sessions 4 and 8, and end of treatment. Bivariate results supported the goal directed traditional CBT model, where obsession scores are temporally associated with subsequent changes in compulsion scores. These results have implications for theoretical and treatment modelling of obsessions and compulsions in OCD treatment.
