The Bank Job: A Field Study of Sexually Discriminatory Performance on a Neutral-Role Task

Sixty-four checks were cashed in a field examination of sex role discrimination using a non-sex-role stereotyped (neutral role) task. Experimenter (customer) sex, subject (teller) sex, amount of the check, and bank branch were varied to produce a 2 × 2 × 2 × 2 design. Transaction times were longer for female customers than for male customers, and were longer with male tellers than with female tellers. Results were interpreted as supporting the hypothesis of greater sex role salience in cross-sex, as compared with same-sex dyads. Suggestions are made for further research using neutral-role tasks to better define certain role concepts.     

Mnemic neglect: Selective amnesia of one’s faults

The mnemic neglect model predicts and accounts for selective memory for social feedback as a function of various feedback properties. At the heart of the model is the mnemic neglect effect (MNE), defined as inferior recall for self-threatening feedback compared to other kinds of feedback. The effect emerges both in mundane realism and minimal feedback settings. The effect is presumed to occur in the service of self-protection motivation. Mnemic neglect is pronounced when the feedback poses high levels of self-threat (i.e., can detect accurately one’s weakness), but is lost when self-threat is averted via a self-affirmation manipulation. Mnemic neglect is caused by self-threatening feedback being processed shallowly and in ways that separate it from stored (positive) self-knowledge. The emergence of mnemic neglect is qualified by situational moderators (extent to which one considers their self-conceptions modifiable, receives feedback from a close source, or is primed with improvement-related constructs) and individual differences moderators (anxiety, dysphoria, or defensive pessimism). Finally, the MNE is present in recall, but absent in recognition. Output interference cannot explain this disparity in results, but an inhibitory repression account (e.g., experiential avoidance) can: Repressors show enhanced mnemic neglect. The findings advance research on memory, motivation, and the self.     

Depth of Field: Using photographs and narratives to explore and reflect on ageing

The learning landscape of the higher education environment is changing, with an increased focus over the past decade on how educators might begin to cultivate reflective skills in health professions students. In addition, changing professional requirements demand that health professionals are adequately prepared to practise in today’s complex healthcare systems, including responding to changing demographics of population ageing. In this educational case study, we will share how we (a group of education, medical and nursing academics) developed ‘Depth of Field: Exploring Ageing’ a digital, consumer-driven, interprofessional reflective learning resource that uses photographs, narrative and small-group work to strengthen reflective capacity in current and/or future health professionals.     

Perceived teasing experiences in body dysmorphic disorder

Individuals with body dysmorphic disorder (BDD) are excessively concerned about imagined or slight defects in their appearance (e.g., asymmetrical facial features). Cognitive-behavioral models of BDD propose that several factors, including dysfunctional appearance-related beliefs and life experiences, such as teasing, contribute to the avoidance behaviors or rituals (e.g., mirror checking, grooming) characteristic of BDD. Previous research has demonstrated an association between perceived teasing and body dissatisfaction. In the current study, we examined whether individuals with BDD (n = 16) report to have been teased more often than do mentally healthy controls (n = 17). The group comprising individuals with BDD reported more appearance- and competency-related teasing than did control participants. This study provides preliminary evidence for the association between perceived teasing and BDD.     

A Regression Framework for Causal Mediation Analysis with Applications to Behavioral Science

We introduce and extend the classical regression framework for conducting mediation analysis from the fit of only one model. Using the essential mediation components (EMCs) allows us to estimate causal mediation effects and their analytical variance. This single-equation approach reduces computation time and permits the use of a rich suite of regression tools that are not easily implemented on a system of three equations. Additionally, we extend this framework to non-nested mediation systems, provide a joint measure of mediation for complex mediation hypotheses, propose new visualizations for mediation effects, and explain why estimates of the total effect may differ depending on the approach used. Using data from social science studies, we also provide extensive illustrations of the usefulness of this framework and its advantages over traditional approaches to mediation analysis. The example data are freely available for download online and we include the R code necessary to reproduce our results.     

Behavioral discrimination of click intensity in cat

Avoidance conditioning procedures were used to train cats to discriminate intensity differences between successive clicks. The discriminative behavior was applied in a modified method of adjustment to determine a difference limen (DL) for click intensity. The obtained DLs were consistent within and between subjects, and averaged 4.4 db. This value is greater than previously reported intensity DLs for pure tones in cats.
