Conceptual implicit memory and environmental context

Changes in environmental context between encoding and retrieval often affect explicit memory but research on implicit memory is equivocal. One proposal is that conceptual but not perceptual priming is influenced by context manipulations. However, findings with conceptual priming may be compromised by explicit contamination. The present study examined the effects of environmental context on conceptual explicit (category-cued recall) and implicit memory (category production). Explicit recall was reduced by context change. The implicit test results depended on test awareness (assessed with a post-test questionnaire). Among test-unaware participants, priming was equivalent for same-context and different-context groups, whereas for the test-aware, the same-context group produced more priming. Thus, when explicit contamination is controlled, changes in environmental context do not impair conceptual priming. Context dependency appears to be a general difference between implicit and explicit memory rather than a difference between conceptual and perceptual implicit memory. Finally, measures of mood indicated no changes in affect across contexts, arguing against mood mediation for the context effects in explicit recall.     

Can a mind have two time lines? Exploring space-time mapping in Mandarin and English speakers

Spatial representations of time are a ubiquitous feature of human cognition. Nevertheless, interesting sociolinguistic variations exist with respect to where in space people locate temporal constructs. For instance, while in English time metaphorically flows horizontally, in Mandarin an additional vertical dimension is employed. Noting that the bilingual mind can flexibly accommodate multiple representations, the present work explored whether Mandarin–English bilinguals possess two mental time lines. Across two experiments, we demonstrated that Mandarin–English bilinguals do indeed employ both horizontal and vertical representations of time. Importantly, subtle variations to cultural context were seen to shape how these time lines were deployed.     

An evaluation of the enhanced cognitive-behavioural model of bulimia nervosa

The original cognitive-behavioural model of bulimia nervosa (BN) has been enhanced to include four additional maintaining mechanisms: low self esteem, clinical perfectionism, interpersonal problems, and mood intolerance. These models have been used to guide cognitive-behavioural treatment for BN, but the enhanced model has yet to be directly evaluated as a whole in a clinical sample. This study aimed to compare and evaluate the original and the enhanced cognitive-behavioural models of BN using structural equation modelling. The Eating Disorder Examination and self-report questionnaires were completed by 162 patients seeking treatment for BN (N = 129) or atypical BN (N = 33). Fit indices suggested that both the original and enhanced models provided a good fit to the data, but the enhanced model accounted for more variance in dietary restraint and binge eating. In the enhanced model, low self esteem was associated with greater overevaluation of weight and shape, which, in turn, was associated with increased dietary restraint. Interpersonal problems were also directly associated with dietary restraint, and binge eating was associated with increased purging. While the current study provides support for some aspects of the enhanced cognitive-behavioural model of BN, some key relationships in the model were not supported, including the important conceptual relationship between dietary restraint and binge eating.     

The colour of gender stereotyping

Despite legislative attempts to eliminate gender stereotyping from society, the propensity to evaluate people on the basis of their sex remains a pernicious social problem. Noting the critical interplay between cultural and cognitive factors in the establishment of stereotypical beliefs, the current investigation explored the extent to which culturally transmitted colour-gender associations (i.e., pink is for girls, blue is for boys) set the stage for the automatic activation and expression of gender stereotypes. Across six experiments, the results demonstrated that (1) consumer choice for children's goods is dominated by gender-stereotyped colours (Experiment 1); (2) colour-based stereotypic associations guide young children's behaviour (Experiment 2); (3) colour-gender associations automatically activate associated stereotypes in adulthood (Experiments 3-5); and (4) colour-based stereotypic associations bias impressions of male and female targets (Experiment 6). These findings indicate that, despite prohibitions against stereotyping, seemingly innocuous societal practices may continue to promote this mode of thought.     

The Arguments of the Tombs of the Unknown: Relationality and National Legitimation

In the wake of the First World War, a new form of commemoration emerged internationally, but in each case focused upon a new kind of national “hero”—the unknown soldier or warrior. The first instances appeared in France and Britain in 1920, followed by the United States in 1921, and Belgium in 1922. Other nations followed suit over the years, with the most recent WWI Unknown Soldier monument dedicated in 2004, in New Zealand. The motivational calculus of these national tombs was, of course, the massive number of combatant dead whose remains could not be identified. This paper takes up the two very different arguments composed by these commemorative sites. The first argument was directed to surviving family members and was articulated most explicitly by the French as a hypothetical enthymeme “this could be your husband, your father, your brother,” etc. The second argument has been directed to national and international collectives as a constitutive proclamation of legitimated nation-state or Empire Although this argument is particularly explicit in postcolonial gestures of independence on the part of former dominions of old empires, it was evident in even the earliest cases of the tombs of the unknown.     

Perceived Job Discrimination: Going beyond a science of mean effects

This comment responds to the major issues raised by the papers of Anseel (2011) and Patterson and Zibarras (2011) as discussant commentaries to my keynote paper on perceived job discrimination (PJD) and applicant propensity to case initiation in employee selection. I respond first to the two main themes noted by these authors – (i) theoretical explanations for PJD, and, (ii) methodological and research design imperatives. In conclusion, this brief paper extends these issues to propose that applicant reactions research needs to develop from being a science of mean reactions to becoming a paradigm that can account for pragmatically important outlier reactions and responses as well.     

Self‐efficacy in the Workplace: Linking personality to domain‐specific efficacy beliefs

Based on a social cognitive approach to personality, the role of domain‐specific efficacy beliefs were examined in two studies. Study 1 developed a measure of expectations about success in 10 different domains of common work activities with domain‐specific expectancy ratings obtained for 157 individuals along with self‐ and peer ratings of personality. Results showed that predictable relationships emerged, with the traits of the five‐factor model being important determinants of construct‐relevant efficacy beliefs. Study 2 focused on expectations about activities related to conscientiousness as a link between personality and performance across jobs. Results (N = 97) confirmed the proposed relationships and found that efficacy beliefs about trait‐relevant tasks functioned as a mediator linking conscientious and supervisor ratings of performance.     

A randomised controlled trial of acceptance-based cognitive behavioural therapy for command hallucinations in psychotic disorders

Command hallucinations represent a special problem for the clinical management of psychosis. While compliance with both non-harmful and harmful commands can be problematic, sometimes in the extreme, active efforts to resist commands may also contribute to their malignancy. Previous research suggests Cognitive Behaviour Therapy (CBT) to be a useful treatment for reducing compliance with harmful command hallucinations. The purpose of this trial was to evaluate whether CBT augmented with acceptance-based strategies from Acceptance and Commitment Therapy could more broadly reduce the negative impact of command hallucinations. Forty-three participants with problematic command hallucinations were randomized to receive 15 sessions of the intervention "TORCH" (Treatment of Resistant Command Hallucinations) or the control, Befriending, then followed up for 6 months. A sub-sample of 17 participants was randomized to a waitlist control before being allocated to TORCH or Befriending. Participants engaged equally well with both treatments. Despite TORCH participants subjectively reporting greater improvement in command hallucinations compared to Befriending participants, the study found no significant group differences in primary and secondary outcome measures based on blinded assessment data. Within-group analyses and comparisons between the combined treatments and waitlist suggested, however, that both treatments were beneficial with a differential pattern of outcomes observed across the two conditions.
