Midsagittal brain shape correlation with intelligence and cognitive performance

Brain shape might influence cognitive performance because of the relationships between functions, spatial organization, and differential volumetric development of cortical areas. Here we analyze the relationships between midsagittal brain shape variation and a set of basic psychological measures. Coordinates in 2D from 102 MRI-scanned young adult human brains were superimposed through a Procrustes approach, and the residual variation was regressed onto 21 cognitive tests performed by the same individuals. Most of the composite and specific variables (including general intelligence, working memory, attention, and executive functions) do not show meaningful correlations with midsagittal brain morphology. However, variables related to mental speed display subtle but consistent correlations with brain shape variation. Such correlations are small, suggesting that the influence of midsagittal brain geometry on individual cognitive performance is negligible. Nevertheless, this evidence can supply information on brain biology and evolution. Areas associated with the parietal cortex appear to be involved in relationships between brain geometry and mental speed. These areas have been associated with relevant endocranial differences between living and extinct humans, and are important as functional and structural components of brain organization. The limited correlation between brain geometry and mental speed among modern individuals might be more relevant when the large paleoneurological variation of the genus Homo is taken into account.     

Psychometric analysis of the AF5 multidimensional scale of self-concept in a sample of adolescents and adults in Catalonia

The aim of this study is to carry out a psychometric study of the AF5 scale in a sample of 4.825 Catalan subjects from 11 to 63 years-old. They are students from secondary compulsory education (ESO), from high school, middle-level vocational training (CFGM) and from the university. Using a principal component analysis (PCA) the theoretical validity of the components is established and the reliability of the instrument is also analyzed. Differential analyses are performed by gender and normative group using a 2 x 6 factorial design. The normative group variable includes the different levels classified into 6 sub-groups: university, post-compulsory secondary education (high school and CFGM), 4th of ESO, 3rd of ESO, 2nd of ESO and 1st of ESO. The results indicate that the reliability of the Catalan version of the scale is similar to the original scale. The factorial structure also fits with the original model established beforehand. Significant differences by normative group in the four components of self-concept explored (social, family, academic/occupational and physical) are observed. By gender, significant differences appear in the component of physical self-concept, academic and social but not in the family component.     

Web of Science production quality indicators of ten professors' at the area of personality, assessment and psychological treatment: additional contributions to Olivas-Ávila y Musi-Lechuga study

Rankings of scientific productivity are increasingly relevant both from an individual and a collective perspective. Therefore, making sure they are based on reliable and exhaustive information is really important. This study clearly shows that available rankings change dramatically when internationally acknowledged bibliometric indices are considered. Data from the 10 Professors belonging to the 'Personality, Assessment, and Psychological Treatment' Department considered in the recent analysis by Olivas-ávila y Musi-Lechuga ( Psicothema 2010. Vol. 22, no 4, pp. 909-916) are revisited here for illustrative purposes.     

DON'T ROCK THE BOAT: WOMEN'S BENEVOLENT SEXISM PREDICTS FEARS OF MARITAL VIOLENCE

We examined how Spanish women's benevolent sexism (a sex-role attitude) affects their perceptions of whether a hypothetical husband will feel threatened by a wife's success at work. In a social perception study, female participants ( N  = 210) read a vignette in which a husband and his wife argued over her job promotion. Women's benevolent sexism (but not hostile sexism) predicted viewing the husband as more threatened by his wife's promotion and more likely to aggress against her (intimate partner violence). The effect of women's benevolent sexism was robust and not mitigated when specific information about the husband's attitude (traditional, egalitarian, no information) was provided. Belief that a husband would feel threatened by a wife's promotion partially mediated the relationship between women's benevolent sexism scores and their anticipation that the husband would become violent. Benevolently sexist women may embrace traditional roles in relationships in part to avoid antagonizing male partners, ultimately maintaining the status quo.     

Comorbid attention-deficit/hyperactivity disorder in borderline patients defines an impulsive subtype of borderline personality disorder

In order to examine the impulsive profile of a BPD sample with comorbid ADHD, adult patients who met criteria for BPD were assessed for ADHD with the CAADID and the WURS. A high rate of ADHD in the BPD sample was found, with sixty-nine (38.1%) BPD patients diagnosed as having comorbid adult ADHD. BPD-ADHD group had higher rates of general substance use disorder (59.4% vs. 38.4%), antisocial personality disorder (7.2% vs. 0.9%) and obsessive-compulsive personality disorder (21.7% vs. 6.3%). The BPD group without comorbid adult ADHD showed a higher rate of mood disorders (62.5% vs. 37.7%), panic disorders (54.5% vs. 23.1%) and benzodiazepine abuse (18.8% vs. 5.8%). Only in BPD patients without ADHD was comorbid avoidant personality disorder found. BPD patients could be distinguished in two clear subgroups related to the adult ADHD comorbidity. BPD-ADHD patients showed a more homogeneous and impulsive profile while BPD without ADHD comorbidity had more anxiety and depressive disorders.     

The Impact of Race‐Based Performance Differences on Perceptions of Test Legitimacy

This paper examines if perceptions of test legitimacy increase when racial differences on test performance match the racial status quo or when a perceiver's in‐group performs better than expected, relative to other groups. Study 1 assesses expected performance difference for various racial groups on a GRE‐like test. Study 2 assesses White and Asian participants' perceptions of legitimacy of a test that either favors the in‐group or an out‐group. Study 3 replicates Study 2 using individuals from high‐ and low‐status groups (Asians and Latinos, respectively). The findings suggest that the desire to benefit the in‐group trumps the desire to justify the status quo in accounting for the impact of race‐based performance differences on perceptions of test legitimacy.     

Voluntary attention increases perceived spatial frequency

Voluntary covert attention selects relevant sensory information for prioritized processing. The behavioral and neural consequences of such selection have been extensively documented, but its phenomenology has received little empirical investigation. Involuntary attention increases perceived spatial frequency (Gobell & Carrasco, 2005), but involuntary attention can differ from voluntary attention in its effects on performance in tasks mediated by spatial resolution (Yeshurun, Montagna, & Carrasco, 2008). Therefore, we ask whether voluntary attention affects the subjective appearance of spatial frequency—a fundamental dimension of visual perception underlying spatial resolution. We used a demanding rapid serial visual presentation task to direct voluntary attention and measured perceived spatial frequency at the attended and unattended locations. Attention increased the perceived spatial frequency of suprathreshold stimuli and also improved performance on a concurrent orientation discrimination task. In the control experiment, we ruled out response bias as an alternative account by using a lengthened interstimulus interval, which allows observers to disengage attention from the cued location. In contrast to the main experiment, the observers showed neither increased perceived spatial frequency nor improved orientation discrimination at the attended location. Thus, this study establishes that voluntary attention increases perceived spatial frequency. This phenomenological consequence links behavioral and neurophysiological studies on the effects of attention.     

Exposure to a specific prompt topography predicts its relative efficiency when teaching intraverbal behavior to children with autism spectrum disorder

Comparisons of the relative efficiency of different prompt topographies (visual or auditory), when teaching intraverbal behavior to children with disabilities, have yielded idiosyncratic results. Recent research has shown that previous exposure to a specific prompt type may affect its efficiency when teaching intraverbal behavior to preschool children. The current study was an attempt to replicate these results with 3 children diagnosed with autism spectrum disorder. For all participants, increased exposure to one prompt topography was sufficient to make it relatively more efficient as measured by number of trials to criterion. These results suggest that previous history with a prompt type may predict its efficiency.     

Simple discrimination training with differential responses to establish functional and equivalence classes with preschool children

The present study assessed whether simple discrimination training with differential responses would produce functional and equivalence classes with preschool children. In Experiment 1, we exposed 10 children to simple successive discrimination training in which they had to press different buttons (selection‐based responses). Response 1 (R1) was reinforced only in the presence of A1, B1, or C1, and Response 2 (R2) was reinforced only in the presence of A2, B2, or C2. We assessed the formation of functional classes by training new selection responses in the presence of one member of each class (A1‐R3, A2‐R4) and testing to see if these responses would occur in the presence of other members. Eight children responded consistently with functional class formation. Four of these eight children also responded consistently with the formation of equivalence classes. Experiment 2 investigated whether differential motor responses (i.e., gestures) would improve equivalence class yields. Three of six children showed both functional and equivalence class formation. In general, the results indicate that the simple discrimination procedure with differential responses yielded functional and equivalence class formation.     

Attachment and coparenting representations in men during the transition to parenthood

Coparenting is based on parents’ representations of themselves as coparents. Attachment theory can be a useful framework to understand the way that different coparenting representations are developed during the transition to parenthood. This study aimed to analyze the association between men's attachment and coparenting representations at the first trimester of pregnancy and from the first trimester of pregnancy to 6 months’ postpartum. A sample of 86 men was recruited and completed self-report measures of attachment and coparenting representations at the first and third trimester of pregnancy and at 1 and 6 months’ postpartum. At the first trimester of pregnancy, higher attachment avoidance was associated with higher lack of coparenting support. From the first trimester of pregnancy to 6 months’ postpartum, higher attachment avoidance was associated with (a) a steeper increase on lack of coparenting support, (b) an increase on coparenting conflict (while low attachment avoidance was associated with a decrease), and (c) a lower decrease on coparenting disagreement. This study may contribute to coparenting research by showing new evidence on attachment theory as a useful framework to understand how different coparenting representations are developed in men during the transition to parenthood.
