Development and Psychometric Properties of the Self-Representation Questionnaire for Adolescents (SRQA)

Given the lack of validated measures of adolescents’ self-representation, in this paper we present the development process and psychometric properties of a new self-representation questionnaire for adolescents (SRQA), aged 12–16 year old. We examined SRQA factor structure through two studies. In the first study, 32 attributes (16 positive and 16 negative), previously validated in three studies, were administered to 239 adolescents (M = 13.8; SD = 1.28). An exploratory factor analysis showed that 21 attributes (13 positive and 8 negative) were organized in five factors: instrumental, social, emotional, intelligence, and physical appearance. In the second study, these 21 attributes were administered to 232 adolescents (M = 13.8; SD = 1.23). A confirmatory factor analysis supported the SRQA five factor model (Model fit: χ ²/df ratio = 2.392; CFI = .90; RMSEA = .08). Internal consistency was acceptable, ranging between .60 and .85. Girls displayed higher scores in the instrumental and social factors, whereas boys presented higher scores on the physical appearance factor. In line with previous research, results regarding age differences were inconsistent: while in Study 1 results suggested that as, age increases, adolescents’ intelligence self-representation becomes more negative, in Study 2 no age differences were found. Concurrent validity of the SRQA was explored through correlations with the Teacher Report Form, filled out by the adolescents’ homeroom teachers. Results revealed significant negative correlations between two dimensions of self-representation (i.e., instrumental and intelligence) and several dimensions of adolescents’ internalizing and externalizing problems, providing evidence of concurrent validity for the SRQA.     

Exposure to sexism can decrease implicit gender stereotype bias

Two studies examined the effect of exposure to sexism on implicit gender bias, focusing specifically on stereotypes of men as competent and women as warm. Male and female participants were exposed to sexism or no sexism. In both Experiment 1 (Implicit Association Task; N = 115) and Experiment 2 (Go/No‐go Association Task; N = 167), women who had been exposed to sexist beliefs demonstrated less implicit gender stereotype bias relative to women who were not exposed to sexism. In contrast, exposure to sexism did not influence men's implicit gender stereotype bias. In Experiment 2, process modelling revealed that women's reduction in bias in response to sexism was related to increased accuracy orientation and a tendency to make warmth versus competence judgments. The implications of these findings for current understandings of sexism and its effects on gender stereotypes are discussed.     

Auditory, visual, tactile, olfactory, and bodily hallucinations in patients with obsessive-compulsive disorder

Although much attention has been paid to patients who lack insight into their obsessional beliefs, less importance has been given to individuals with obsessive-compulsive disorder (OCD) who display perceptual disturbances typically found in psychotic disorders, including schizophrenia, schizoaffective disorders, or mood disorders with psychotic features. We would like to call the attention to a phenomenon that has been neglected in the psychiatric literature: the occurrence of hallucinations and related phenomena in patients with OCD. In this case report, we describe five clinical vignettes of patients with OCD with hallucinations in several different sensory modalities, including the auditory, the visual, the tactile, the olfactory, and the cenesthetic ones. Further psychopathological research should clarify the clinical significance of hallucinations among patients with OCD.     

The Development of Metacognitive Monitoring and Control in Second Graders: A Short-Term Longitudinal Study

Although metacognition is considered a central aspect of self-regulated learning and is often linked to learning outcomes, little is known about the intraindividual development and factors that lead to developmental improvement over time. This longitudinal study investigated 2nd graders’ (N = 119, aged 8–9 years) metacognitive monitoring and control abilities in the context of spelling. Children were tested at the beginning (T₁) and at the end of their 2nd school year (T₂). The study focused on the development of monitoring and control, their interplay at both measurement points and across time, and the cross-sectional and longitudinal impact of 1st-order task performance (here, spelling) on the 2 metacognitive processes. Results revealed substantial developmental progression in most monitoring and control measures. Monitoring and control were interrelated cross-sectionally only at T₂, but longitudinally, control predicted monitoring. Interestingly, earlier spelling performance predicted not only later spelling, but also later monitoring and control abilities. The findings indicate that earlier domain-specific skills in the 1st-order task (i.e., spelling) are 1 of several possible driving forces for metacognitive development.     

Motor Cortex Plasticity in Children With Spastic Cerebral Palsy: A Systematic Review

A review of the literature was performed to answer the following questions: Does motor cortex excitability correlate with motor function? Do motor cortex excitability and cortex activation change after a rehabilitation program that results in improvements in motor outcomes? Can the 10–20 electroencephalography (EEG) system be used to locate the primary motor cortex when employing transcranial direct current stimulation? Is there a bihemispheric imbalance in individuals with cerebral palsy similar to what is observed in stroke survivors? the authors found there is an adaptation in the geometry of motor areas and the cortical representation of movement is variable following a brain lesion. The 10–20 EEG system may not be the best option for locating the primary motor cortex and positioning electrodes for noninvasive brain stimulation in children with cerebral palsy.     

An Integrative Model of the Impact of Exposure to Idealized Female Images on Adolescent Girls’ Body Satisfaction1

This research examined a model describing the interrelationships between individual characteristics and the extent of change in body dissatisfaction following exposure to idealized female images. Three samples of middle adolescent girls (2 Australian, n = 118, and n = 63; 1 Italian, n = 88) completed self‐report assessments. Several days later, they viewed idealized female images, and body satisfaction was assessed immediately prior to and following exposure. Across all 3 samples, structural equation modeling supported a model in which body comparison tendency mediated the role of psychological functioning and internalization of the thin ideal on changes in body satisfaction following image exposure. Internalization of the thin ideal partially mediated the path between psychological functioning and body comparison tendency.     

Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters

This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the opponents could be one of the causes of the differences observed in the behavior of the aggressive males confronting them. However, more research is needed to study if other variables, such as the production of odors, are also affected by the state (deprived or intact) of the olfactory sense. These findings provide additional support for the view that the type of opponent used in studies on intermale aggression is of paramount importance.Aggr.

Age-Related Changes in Smoothness of Gait of Healthy Children and Early Adolescents

Abstract

In this study, we acquired and processed trunk accelerations during level walking in 85 children aged 8-13?years to calculate spatio-temporal parameters and Harmonic Ratio (HR), which is a metrics representative of gait smoothness and step-to-step symmetry. The results show that while spatio-temporal parameters remain unchanged once normalized considering individuals’ anthropometry, significantly higher values of HR for both the antero-posterior and vertical directions were found in participants aged 12–13 with respect to those of 8–9. This indicates an improvement of gait symmetry, which suggests that the gait maturation process is still ongoing for the age ranges tested here.
