Inhibition: Mental Control Process or Mental Resource?

The current study tested 2 models of inhibition in 45 children with language impairment and 45 children with normally developing language; children were aged 7 to 12 years. Of interest was whether a model of inhibition as a mental-control process (i.e., executive function) or as a mental resource would more accurately reflect the relations among mental-attentional (M) capacity, inhibition, updating, shifting, and language competence. Children completed measures of M-capacity (in the verbal and nonverbal domains), inhibition, updating, shifting, and language. Path analyses showed the data provided a poor fit to the model of inhibition as a mental-control process but a good fit to the model of inhibition as a mental resource. Results are consistent with the theory of constructive operators and suggest inhibition is a mental resource rather than a mental-control process.     

Converging evidence of configural processing of faces in high-functioning adults with autism spectrum disorders

There is conflicting evidence about whether individuals with autism spectrum disorder (ASD) demonstrate configural processing of faces. We examined two types of configural processing of unfamiliar faces in high-functioning adults with ASD: Holistic processing (processing a face as a gestalt percept) and processing of second-order relations (the spatial relations among facial features, e.g., distance between two eyes). Compared to age- and IQ-matched typical adults, 17 adults with ASD demonstrated normal holistic processing (as demonstrated by the composite face effect), normal sensitivity to second-order relations in upright faces, and the expected disruption of sensitivity to second-order relations in inverted faces. They were also normal in using the internal features and shape of the external contour to make same/different judgements about facial identity. The results provide converging evidence of configural processing of unfamiliar faces in high-functioning adults with ASD, and bring into question the generalizability of previous reports of abnormal face processing in individuals with ASD.     

Personality, personal model beliefs, and self-care in adolescents and young adults with Type 1 diabetes.

This study compared 3 models of association between personality, personal model beliefs, and self-care in a cross-sectional design. These models were as follows: (a) Emotional stability determines self-care indirectly through personal model beliefs, and conscientiousness is a direct predictor of self-care; (b) emotional stability determines self-care indirectly through personal model beliefs, and conscientiousness moderates the association between beliefs and self-care; (c) both emotional stability and conscientiousness determine self-care indirectly through personal model beliefs. Participants (N = 358, aged 12-30 years) with Type 1 diabetes completed measures of personality, personal model beliefs, and self-care. Structural equation modeling indicated that Model C was the best fit to the data.     

Personality traits, perceived risk, and risk-reduction behaviors: a further study of smoking and radon.

Personality traits and risk perceptions were examined as predictors of changes in smoking behavior. Participants (N = 697) were part of a randomized controlled trial of interventions to reduce exposure to the combined hazard of radon and cigarette smoke. Participants with higher perceived risk at baseline for the combination of smoking and radon were more likely to have a more restrictive household smoking ban in place at 12-month follow-up (p < .05). Risk perceptions also predicted reductions in the total number of cigarettes smoked in the home for participants in the video intervention who had high or moderate levels of extraversion (p < .01). Greater perceived risk predicted whether highly or moderately conscientious women quit smoking (p < .05). The moderating effects of personality traits should be considered when evaluating risk-reduction interventions.     

Reduced adaptability,but no fundamental disruption,of norm‐based face coding following early visual deprivation from congenital cataracts

Faces are adaptively coded relative to visual norms that are updated by experience, and this adaptive coding is linked to face recognition ability. Here we investigated whether adaptive coding of faces is disrupted in individuals (adolescents and adults) who experience face recognition difficulties following visual deprivation from congenital cataracts in infancy. We measured adaptive coding using face identity aftereffects, where smaller aftereffects indicate less adaptive updating of face‐coding mechanisms by experience. We also examined whether the aftereffects increase with adaptor identity strength, consistent with norm‐based coding of identity, as in typical populations, or whether they show a different pattern indicating some more fundamental disruption of face‐coding mechanisms. Cataract‐reversal patients showed significantly smaller face identity aftereffects than did controls (Experiments 1 and 2). However, their aftereffects increased significantly with adaptor strength, consistent with norm‐based coding (Experiment 2). Thus we found reduced adaptability but no fundamental disruption of norm‐based face‐coding mechanisms in cataract‐reversal patients. Our results suggest that early visual experience is important for the normal development of adaptive face‐coding mechanisms.     

Branding ‘Canadian Experience’ in Immigration Policy: Nation Building in a Neoliberal Era

This paper examines the branding of ‘Canadian experience’ in Canadian immigration policy as a rhetorical strategy for neoliberal nation-building. Since 2008, the Canadian government has introduced an unprecedented number of changes to immigration policy. While the bulk of these policies produce more temporary and precarious forms of migration, the Canadian government has mobilized the rhetoric of ‘Canadian experience’ as a means to identify immigrants who carry the promise of economic and social integration. Through a critical discourse analysis of Canadian print media and political discourse, we trace how the brand of Canadian experience taps into the affective value of national identity in an era of global economic insecurity. We also illustrate how the discourse of Canadian experience (CE) remains ideologically deracialized, such that the government’s embrace of CE as an immigrant selection criterion dismisses the discriminatory effects that this discourse is shown to have for racialized immigrants in Canada.     

Changes in search rate but not in the dynamics of exogenous attention in action videogame players

Many previous studies have shown that the speed of processing in attentionally demanding tasks seems enhanced following habitual action videogame play. However, using one of the diagnostic tasks for efficiency of attentional processing, a visual search task, Castel and collaborators (Castel, Pratt, & Drummond, Acta Psychologica 119:217-230, 2005) reported no difference in visual search rates, instead proposing that action gaming may change response execution time rather than the efficiency of visual selective attention per se. Here we used two hard visual search tasks, one measuring reaction time and the other accuracy, to test whether visual search rate may be changed by action videogame play. We found greater search rates in the gamer group than in the nongamer controls, consistent with increased efficiency in visual selective attention. We then asked how general the change in attentional throughput noted so far in gamers might be by testing whether exogenous attentional cues would lead to a disproportional enhancement in throughput in gamers as compared to nongamers. Interestingly, exogenous cues were found to enhance throughput equivalently between gamers and nongamers, suggesting that not all mechanisms known to enhance throughput are similarly enhanced in action videogamers.     

His and Her Perspectives: Gender Ideology, Work-to-Family Conflict, and Marital Satisfaction

This study examines the relationships between gender ideology, work-to-family conflict, and marital satisfaction. We hypothesize that gender ideology will moderate relationships between both the respondent’s work-to-family conflict and their spouse’s work-to-family conflict in predicting marital satisfaction, and that spouses’ gender ideologies will interact in predicting marital satisfaction. The hypotheses are addressed using data from a random sample of U.S. dual-earner couples (N?=?156) in a western state. The findings indicate that the more egalitarian women’s gender ideologies, the stronger the negative relationship between women’s marital satisfaction and women’s work-to-family conflict. The results also indicate that the dependence of men’s marital satisfaction on wives’ gender ideologies varies according to men’s own gender ideologies. Implications of the study are discussed.
