Stigma and Barriers to Mental Health Care in Deployed Canadian Forces Personnel

Mental disorders are prevalent on deployed operations, but only a small fraction of those with problems access care due to a range of barriers. A survey measuring need for care, perceived barriers, and care-seeking propensity was administered to Canadian Forces personnel during deployment in Afghanistan. Complex characteristics of barriers to care on deployment were found: stigma had no association with care-seeking propensity; perceived structural barriers were associated with greater care-seeking propensity; and perceived structural barriers were greater in more isolated locations. Only negative attitudes toward care had the expected negative association with care-seeking propensity. Research and practical considerations are discussed.

Two plus blue equals green: Grapheme-color synesthesia allows cognitive access to numerical information via color

In grapheme-color synesthesia, graphemes (e.g., numbers or letters) evoke color experiences. It is generally reported that the opposite is not true: colors will not generate experiences of graphemes or their associated information. However, recent research has provided evidence that colors can implicitly elicit symbolic representations of associated graphemes. Here, we examine if these representations can be cognitively accessed. Using a mathematical verification task replacing graphemes with color patches, we find that synesthetes can verify such problems with colors as accurately as with graphemes. Doing so, however, takes time: ～250 ms per color. Moreover, we find minimal reaction time switch-costs for switching between computing with graphemes and colors. This demonstrates that given specific task demands, synesthetes can cognitively access numerical information elicited by physical colors, and they do so as accurately as with graphemes. We discuss these results in the context of possible cognitive strategies used to access the information.     

Factors Associated with Non-Reimbursable Activity on an Inpatient Pediatric Consultation–Liaison Service

The aim of this study was to identify factors contributing to clinician time spent in non-reimbursable activity on an inpatient pediatric consultation–liaison (C–L) service. A retrospective study was conducted using inpatient C–L service data on 1,246 consecutive referrals. For this patient population, the strongest predictor of level of non-reimbursable clinical activity was illness chronicity and the number of contacts with C–L service clinicians during their hospital stay. Patients with acute life-threatening illnesses required the highest mean amount of non-reimbursable service activity. On average, 28 % of total clinician time in completing a hospital consultation was spent in non-reimbursable activity. Effective C–L services require a proportion of time spent in non-reimbursable clinical activity, such as liaison and coordinating care with other providers. Identifying referral and systemic factors contributing to non-reimbursable activity can provide insight into budgeting/negotiating for institutional support for essential clinical and non-clinical functions in providing competent quality patient care.     

Parallel associative processing in the dorsal striatum: segregation of stimulus-response and cognitive control subregions

Although evidence suggests that the dorsal striatum contributes to multiple learning and memory functions, there nevertheless remains considerable disagreement on the specific associative roles of different neuroanatomical subregions. We review evidence indicating that the dorsolateral striatum (DLS) is a substrate for stimulus–response habit formation – incremental strengthening of simple S–R bonds – via input from sensorimotor neocortex while the dorsomedial striatum (DMS) contributes to behavioral flexibility – the cognitive control of behavior – via prefrontal and limbic circuits engaged in relational and spatial information processing. The parallel circuits through dorsal striatum interact with incentive/affective motivational processing in the ventral striatum and portions of the prefrontal cortex leading to overt responding under specific testing conditions. Converging evidence obtained through a detailed task analysis and neurobehavioral assessment is beginning to illuminate striatal subregional interactions and relations to the rest of the mammalian brain.     

Calling and work-related outcomes: Career commitment as a mediator

The current study tested the hypothesis that experiencing a calling to a particular career would relate positively to work-related outcomes, and that these relations would be mediated by career commitment. Using a sample of 370 employees representing diverse occupations at a Western research university, results supported these hypotheses as calling moderately correlated with career commitment, job satisfaction, and organizational commitment and weakly correlated with withdrawal intentions. Career commitment was found to fully mediate the calling–job satisfaction relation, partially mediate the calling–organizational commitment relation, and act as a suppressor in the relation between calling and withdrawal intentions; calling was associated with somewhat greater withdrawal intentions once a person's level of career commitment was taken into consideration. These results suggest that career commitment may represent a critical link between calling and work-related well-being. Implications for research and practice are explored.     

Interteaching: the impact of lectures on student performance

Several studies suggest that interteaching improves student learning more than traditional lectures, but few have examined which components of interteaching contribute to its efficacy. We examined whether the lecture component of interteaching affected students' exam grades and cumulative point totals in a research methods course. Although students who received lectures had consistently higher exam scores than students who did not, the differences were statistically significant on only 2 of 5 exams. Students who received lectures, however, earned significantly more points during the semester.     

Assessing within-person personality variability via frequency estimation: More evidence for a new measurement approach

Variability in personality has been recognized in recent years as an important aspect of personality both conceptually and empirically. A relatively new and efficient method of obtaining variability information is frequency-based personality assessment (Edwards & Woehr, 2007). The purpose of the present research is to further examine the viability of frequency-based personality measurement as an alternative to traditional (Likert-type) measurement and to assess the usefulness of the variance-based parameters. Toward this end, three studies are presented. Specifically, Study 1 examined relationships between a frequency-based measure of the Big Five personality traits and several motivational variables. Study 2 examined the moderating role of temporal consistency information (provided by frequency-based measurement) on relationships between personality and peer ratings of task performance. Study 3 compared the frequency-based measure to a Likert-type measure with respect to each measure’s susceptibility to deliberate response distortion. Results indicated that consistency information increases the predictive validity of agreeableness and conscientiousness and that a frequency-based format is less susceptible to faking than a Likert-type format for conscientiousness, emotional stability, and openness to experience.     

Preliminary Evidence for Associations of CHRM2 with Substance Use and Disinhibition in Adolescence

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral disinhibition, during adolescence. The cholinergic muscarinic receptor 2 gene (CHRM2) is a promising candidate for studying genetic influences on broad-based risk for externalizing traits. This study examined a candidate CHRM2 polymorphism (rs1455858) in relation to substance use and personality measures of disinhibition in a sample of high-risk adolescents (n?=?124). Bivariate analyses and structural equation modeling (SEM) evaluated associations of rs1455858 with measures of drug involvement (alcohol, tobacco and marijuana) and disinhibition (indexed by impulsivity and sensation seeking scores). Bivariate analyses showed significant associations of CHRM2 with several behavioral phenotypes. In SEM analyses CHRM2 related significantly to latent measures of substance use and disinhibition; additionally, disinhibition mediated the association of CHRM2 with substance use. These results suggest that CHRM2 variants are potentially relevant for adolescent substance use and that temperamental risk factors could contribute to these associations.
