Enhancing theory of mind in behavioural variant frontotemporal dementia with transcranial direct current stimulation

Behavioural variant frontotemporal dementia (bvFTD) is a form of frontotemporal degeneration characterized by early changes in personality, emotional blunting, and/or loss of empathy. Recent research has highlighted that these features may be at least partially explained by impairments in the theory of mind (ToM; i.e., the ability to understand and predict other people’s behaviour by attributing independent mental states to them). The aim of this randomized, double-blind, placebo-controlled study was to test the hypothesis that transcranial direct current stimulation (tDCS) over the medial frontal cortex (MFC) selectively enhances communicative intention processing, a specific ToM ability. Using a single-session online design, we administered a ToM task that measures the ability to represent other people’s private and communicative intentions during active or sham tDCS to 16 bvFTD patients. To assess the impact of dementia on performance on the ToM task, we included 16 age-matched healthy volunteers who were asked to perform the entire experimental ToM task. BvFTD is characterized by an impairment in the comprehension of both communicative and private intentions relative to a healthy control group and by a disproportional impairment in communicative intention compared with private intention processing. Significant and selective accuracy improvement in the comprehension of communicative intentions after active stimulation was observed in patients with bvFTD. This is the first study that analyses ToM ability in patients with bvFTD using tDCS stimulation. Our findings could potentially contribute to the development of an effective, noninvasive brain stimulation treatment of ToM impairments in patients with bvFTD.     

Genetic Counseling in the Era of Genomics: What’s all the Fuss about?

As genomic sequencing becomes more widely available in clinical settings for diagnostic purposes, a number of genetic counseling issues are gaining precedence. The ability to manage these issues will be paramount as genetic and non-genetic healthcare professionals navigate the complexities of using genomic technologies to facilitate diagnosis and inform patient management. Counseling issues arising when counseling for diagnostic genomic sequencing were identified by four genetic counselors with 10 years of collective experience providing genetic counseling in this setting. These issues were discussed and refined at a meeting of genetic counselors working in clinical genomics settings in Melbourne, Australia. Emerging counseling issues, or variations of established counseling issues, were identified from the issues raised. Illustrative cases were selected where pre- and post-test genetic counseling was provided in clinical settings to individuals who received singleton or trio WES with targeted analysis. Counseling issues discussed in this paper include a reappraisal of how genetic counselors manage hope in the genomic era, informed consent for secondary use of genomic data, clinical reanalysis of genomic data, unexpected or unsolicited secondary findings, and trio sequencing. The authors seek to contribute to the evolving understanding of genetic counseling for diagnostic genomic sequencing through considering the applicability of existing genetic counseling competencies to managing emerging counseling issues and discussing genetic counseling practice implications.     

Sexual Harassment,Racial Harassment,and Well-Being among Asian American Women: An Intersectional Approach

ABSTRACT

Harassment of Asian American (AA) women has received little attention in popular culture and academic research despite their long legacy of sexualized racial stereotyping (e.g., Geisha, sexually submissive; Shimizu, 2007) and additional risk of mistreatment due to their membership in both marginalized gender and racial groups (Beale, 1970 Beale, F. (1970). Double jeopardy: To be Black and female. In T. C. Bambara (Ed.), The Black woman: An anthology (pp. 90–100). New York: New American Library. [Google Scholar]; Settles & Buchanan, 2014 Settles, I. H., & Buchanan, N. T. (2014). Intersectionality: Multiple categories of identity and difference. In V. Benet-Martinez and Y. Hong (Eds.), The Oxford Handbook of Multicultural Identity (pp. 160–180). New York, NY: Oxford University Press, Inc. [Google Scholar]). This study addresses this dearth of research using an intersectional theoretical framework to comprehensively examine sexual and racial harassment with a sample of AA women. Results validated the underlying factor structure of the Sexual Experiences Questionnaire (Fitzgerald, Gelfand, & Drasgow, 1995 Fitzgerald, L. F., Gelfand, M. J., & Drasgow, F. (1995). Measuring sexual harassment: Theoretical and psychometric advances. Basic and Applied Social Psychology, 17, 425–445. doi:10.1207/s15324834basp1704_2[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) and the Racial Acts, Crimes, and Experiences Scale (RACES; Bergman & Buchanan, 2008 Bergman, M., & Buchanan, N. T. (2008). Development of the Racial Acts, Crimes, and Experiences Survey (RACES). Unpublished instrument. [Google Scholar]) for AA women. Additionally, our results replicated previous research indicating that participants often reported experiencing behaviors that constitute harassment, but did not label them as such. This supports the use of behavioral measures over items that require individuals to label their experiences as harassment. Finally, we examined the associations between these forms of harassment and two indicators of psychological well-being, depression, and posttraumatic stress (PTS). Our results found that gender harassment was associated with more depression, whereas unwanted sexual attention, sexual coercion, and racial harassment were associated with increased PTS. This supports the utility of including both sexual and racial harassment in providing a more nuanced understanding of AA women’s harassment experiences overall and the relationship of harassment to psychological well-being. We discuss theoretical and clinical implications of these findings.     

Measuring work styles: Towards an understanding of the dynamic components of the theory of work adjustment

Work styles are an important yet largely unexplored component of the theory of work adjustment (TWA), describing a dynamic component of how individuals maintain and adjust fit with their work environment. The active work style (AWS) scale is the first attempt to develop a specific self-report measure of work styles suitable for longitudinal research. Results from three studies support Dawis and Lofquist's (1984) proposed four factor structure, but these factors are related through a second-order factor describing a person's generalised level of work activity and effort across time. The AWS scale demonstrated good evidence for reliability and validity, and strong measurement invariance across time signifying its suitability for longitudinal research. In line with expectations, overall work style was positively related to conscientiousness and work engagement yet unrelated to stress. When controlling for these variables, AWS was positively related to demands–abilities fit, but not needs–supplies fit. Limitations and possibilities for future research are also discussed.     

Values and helping behavior: A study in four cultures

Values are important factors in determining individuals' behaviours. Previous studies have examined the relations between values and helping behaviour, but usually in the context of a single culture. The current study examines the relations between personal value types and helping behaviour among university students (N = 722) in four cultures (Germany, Scotland‐UK, Israel and Turkey). Across cultures, the value types of self‐transcendence versus self‐enhancement and conservation versus openness to change were positively related to helping. Specifically, self‐transcendence values were positively related, and self‐enhancement and openness to change values negatively related, to helping behaviour. The correlations pattern did not differ significantly between cultures.     

The nature of restructuring in insight: An individual-differences approach

The insightful problem-solving process has been proposed to involve three main phases: an initial representation phase, in which the solver inappropriately represents the problem; an initial search through the faulty problem space that may lead to impasse; and a postimpasse restructuring phase. Some theories propose that the restructuring phase involves controlled search processes, whereas other theories propose that restructuring is achieved through the automatic redistribution of activation in long-term memory. In this study, we used correlations between working memory (WM) span measures and problemsolving success to test the predictions of these different theories. One group of participants received a set of insight problems that allowed for a large initial faulty search space, whereas another group received a matched set that constrained the initial faulty search space in order to isolate the restructuring phase of the insightful process. The results suggest that increased ability to control attention (as measured by WM span tasks) predicts an individual’s ability to successfully solve problems that involve both the initial search phase and the restructuring phase. However, individual differences in ability to control attention do not predict success on problems that isolate the restructuring phase. These results are interpreted as supporting an automatic-redistribution-of-activation account of restructuring.     

Microstimulation reveals opposing influences of prelimbic and infralimbic cortex on the expression of conditioned fear

Recent studies using lesion, infusion, and unit-recording techniques suggest that the infralimbic (IL) subregion of medial prefrontal cortex (mPFC) is necessary for the inhibition of conditioned fear following extinction. Brief microstimulation of IL paired with conditioned tones, designed to mimic neuronal tone responses, reduces the expression of conditioned fear to the tone. In the present study we used microstimulation to investigate the role of additional mPFC subregions: the prelimbic (PL), dorsal anterior cingulate (ACd), and medial precentral (PrCm) cortices in the expression and extinction of conditioned fear. These are tone-responsive areas that have been implicated in both acquisition and extinction of conditioned fear. In contrast to IL, microstimulation of PL increased the expression of conditioned fear and prevented extinction. Microstimulation of ACd and PrCm had no effect. Under low-footshock conditions (to avoid ceiling levels of freezing), microstimulation of PL and IL had opposite effects, respectively increasing and decreasing freezing to the conditioned tone. We suggest that PL excites amygdala output and IL inhibits amygdala output, providing a mechanism for bidirectional modulation of fear expression.     

Stereotype Directionality and Attractiveness Stereotyping: Is Beauty Good or is Ugly Bad?

Dion, Berscheid, and Walster (1972), in their seminal article, labeled the attribution of positive characteristics to attractive people the "beauty-is-good" stereotype. The stereotyping literature since then provides extensive evidence for the differential judgment and treatment of attractive versus unattractive people, but does not indicate whether it is an advantage to be attractive or a disadvantage to be unattractive. Two studies investigated the direction of attractiveness stereotyping by comparing judgments of positive and negative attributes for medium vs. low and medium vs. high attractive faces. Taken together, results for adults (Experiment 1) and children (Experiment 2) suggest that most often, unattractiveness is a disadvantage, consistent with negativity bias (e.g., Rozin & Royzman, 2001) but contrary to the "beauty-is-good" aphorism.     

Speakers gaze at objects while preparing intentionally inaccurate labels for them

When describing scenes, speakers gaze at objects while preparing their names (Z. M. Griffin & K. Bock, 2000). In this study, the authors investigated whether gazes to referents occurred in the absence of a correspondence between visual features and word meaning. Speakers gazed significantly longer at objects before intentionally labeling them inaccurately with the names of similar things (e.g., calling a horse a dog) than when labeling them accurately. This held for grammatical subjects and objects as well as agents and patients. Moreover, the time spent gazing at a referent before labeling it with a novel word or accurate name was similar and decreased as speakers gained experience using the novel word. These results suggest that visual attention in speaking may be directed toward referents in the absence of any association between their visual forms and the words used to talk about them.     

Psychiatric hospitalization after deliberate self-poisoning

The decision for psychiatric hospitalization after deliberate self-poisoning (DSP) is not well understood. This study, a longitudinal cohort study of 3,148 consecutive DSP patients found 920 (29.2%) subjects were referred for psychiatric hospitalization, 576 (18.3%) on involuntary basis. A logistic regression analysis showed increased risk for: age 25 or older, homelessness, unemployment, previous self-harm, psychiatric inpatient treatment within 12 months, earlier psychiatric inpatient treatment, suicidal ideation or plan, mood or psychotic disorders, and lower clinician experience; and lower risk for being married/defacto, and after hours presentation. Recommendation for psychiatric hospitalization was based on complex decision making. These findings have implications for clinical practice guidelines, service costs, and service organization.
