Hemispheric asymmetry in discriminating faces differing for featural or configural (second-order relations) aspects

The human capacity to discriminate among different faces relies on distinct parallel subprocesses, based either on the analysis of configural aspects or on the sequential analysis of the single elements of a face. A particular type of configural processing consists of considering whether two faces differ in terms of internal spacing among their features, referred to as second-order relations processing. Findings from electrophysiological, neuroimaging, and lesion studies suggest that, overall, configural processes rely more on the right hemisphere, whereas analysis of single features would involve more the left. However, results are not always consistent, and behavioral evidence for a right-hemisphere specialization in second-order relations processing is lacking. Here, we used divided visual field presentation to investigate the possible different contributions of the two hemispheres to face discrimination based on relational versus featural processing. Our data indicate a right-hemispheric specialization in relational processing of upright (but not inverted) faces. Furthermore, we provide evidence regarding the involvement of both the right and left hemispheres in the processing of faces differing for inner features, suggesting that both analytical and configural modes of processing are at play.

Executive functions,math anxiety and math performance in middle school students

Previous studies mainly investigated working memory (WM) and math anxiety (MA) leaving almost unexplored other aspects of executive functions (EFs) in middle school period. Filling the gap in the literature, the aims of this study were: (1) to better examine the relationship between MA and math performance, (2) to better examine the relationship between EFs and math performance and (3) to investigate the interplay between EFs and MA on math performances. This study confirmed a significant and negative relationship between MA and math performance, indicates a significant and positive relationship between visuospatial WM and math performance, shifting and math performance and highlight a scarcely investigated indirect influence of MA through the measure of shifting on math performance. Our findings shed further light on the mediating role of EFs between MA and math performance and underline some future perspectives.     

Reciprocal Relations Between Emotional Self‐Efficacy Beliefs and Ego‐Resiliency Across Time

The present study examined the longitudinal relations of adolescents' self‐reported ego‐resiliency to their emotional self‐efficacy beliefs in expressing positive emotions and in managing negative emotions as they moved into early adulthood. Participants were 239 females and 211 males with a mean age of 17 years (SD = .80) at T1, 19 years (SD = .80) at T2, 21 years (SD = .82) at T3, and 25 years (SD = .80) at T4. A four‐wave cross‐lagged regression model and mediational analyses were used. In a panel structural equation model controlling for the stability of the constructs, reciprocal relationships across time were found between ego‐resiliency and emotional self‐efficacy beliefs related to the expression of positive emotions and to the management of negative emotions. Moreover, the relation between ego‐resiliency assessed at T1 and T3, and ego‐resiliency assessed at T2 and T4, was mediated through emotional self‐efficacy beliefs (at T2 and T3, respectively), and vice versa. The posited conceptual model accounted for a significant portion of variance in ego‐resiliency and has implications for understanding the development of ego‐resiliency.     

DS14 is more likely to measure depression rather than a personality disposition in patients with acute coronary syndrome

It has been suggested that Type D Personality is a risk factor for acute coronary syndrome (ACS) and the DS14 has been developed for its assessment. However, some of the items on the DS14 seem to evaluate depressive symptoms rather than personality features. Therefore, the present study aims to verify whether an overlap exists between the constructs of Type D Personality and depression. Three‐hundred‐and‐four consecutive patients who were both presenting their first ACS and had no history of major depression completed the Hospital Anxiety and Depression Scale (HADS) and the DS14 to assess Type D personality at baseline and have been re‐evaluated at 1, 2, 4, 6, 9 and 12‐month follow‐ups. Out of 304 subjects (80.6% males), 40 were diagnosed as depressed. An exploratory factor analysis of HADS and the DS14 in the second month revealed that four out of seven items on the depressive subscale of HADS (HADS‐D) and six out of seven items on the Negative Affectivity (NA) subscale of the DS14 segregated on the same factor. Results were verified by a Partial Confirmatory Factor Analysis performed at the twelfth month when most of the patients achieved complete remission from the depressive episode. Temporal stability was poor for NA and Type D Personality and these construct co‐vary with HADS‐D over time. Our data suggests that NA and depression are overlapping constructs, supporting the idea that the DS14 measures depressed features, rather than a personality disposition.     

Neuropsychological tools to predict conversion from amnestic mild cognitive impairment to dementia. The TREDEM Registry

Most of the studies about conversion from Mild cognitive impairment (MCI) to dementia have focused on amnestic MCI (aMCI) which is considered a preclinical phase of Alzheimer’s disease. The aim of the present study was to identify neuropsychological tools that would best predict conversion from aMCI to dementia. Fifty-five aMCI subjects on the Treviso Dementia Registry were investigated. They underwent a neuropsychological evaluation during their first assessment and again at follow-up. Cox proportional-hazard regression models were created to measure the association between the dependent variable (dementia diagnosis or MCI status maintenance) and the neuropsychological test scores at baseline. The sample (28 women and 27 men; mean age 76.82 ± 5.88 years; education 7.62 ± 3.99 years) was observed for an average time of 2.17 ± 1.25 years. A Cox backward stepwise regression showed that the Rey Auditory Verbal Learning Test, Delayed Recall (p = .041) and Semantic Verbal Fluency tests (p = .031) appear to be useful in predicting conversion to dementia.     

Shades of Sexualization: When Sexualization Becomes Sexual Objectification

Sexualization in mass media is a widespread phenomenon. Although sexualization and sexual objectification are often used as synonymous, they are two different concepts. Across two studies, we investigated how sexualization affects perceptions of women (Study 1) and men (Study 2) as sexual objects. Participants were asked to judge sexual objectification, competence, and sexiness of female and male models portrayed with different degrees of sexualization, namely, as Non-Revealing (dressed), merely Revealing (undressed), and Sexualized Revealing (undressed and provocative). The results of both studies showed that as the level of sexualization increased so did participants’ perceptions of the targets as sexual objects. However, the level of sexualization affected perceived competence and sexiness differently depending on the target’s gender. Male models’ competence decreased as the level of sexualization increased, whereas female models portrayed as merely Revealing and as Sexualized Revealing were judged as equally incompetent. Male targets’ sexiness was not affected by the level of portrayals’ sexualization, whereas Sexualized Revealing portrayals enhanced the perceived sexiness of female targets. Finally, in Study 2, the results showed that male targets in Sexualized Revealing portrayals were judged as less masculine. Our findings suggest that sexualization contributes similarly to the perception of both women and men as sexual objects but affects other variables depending on the target’s gender. Our work extends previous literature and informs us about the consequences that sexualization of men and women have on others’ judgments.     

Effects of 7.5% CO2-Induced Anxiety on Individual Performance During a Group Computer Combat Game

The inhalation of 7.5% CO₂ has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO₂ gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO₂ compared with air, indicating CO₂-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO₂ inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.     

Attentional WM is not necessarily specifically related with fluid intelligence: the case of smart children with ADHD symptoms

Executive functions and, in particular, Attentional (active) Working Memory (WM) have been associated with fluid intelligence. The association contrasts with the hypothesis that children with ADHD exhibit problems with WM tasks requiring controlled attention and may have a good fluid intelligence. This paper examines whether children who are intelligent but present ADHD symptoms fail in attentional WM tasks. The latter result would be problematic for theories assuming the generality of a strict relationship between intelligence and WM. To study these issues, a battery of tests was administered to a group of 58 children who all displayed symptoms of ADHD. All children were between the age of 8 and 11 years, and were described by their teachers as smart. Children were compared to a control group matched for age, schooling, and gender. The battery included a test of fluid intelligence (Raven’s Coloured Matrices), and a series of visuospatial WM tasks. Results showed that children with ADHD were high in intelligence but significantly lower than the controls in WM tasks requiring high attentional control, whereas there was no difference in WM tasks requiring low attentional control. Furthermore, only high attentional control WM tasks were significantly related to Raven’s performance in the control group, whereas all WM tasks were similarly related in the ADHD group. It is concluded that performance in high attentional control WM tasks may be related to fluid intelligence, but also to a specific control component that is independent of intelligence and is poor in children with ADHD.
