Sexual behavior in Spanish adolescents of divorced parents

Marital breakup has been associated with numerous behavioral problems in children, such as sexual risk behaviors. This research is the first to examine sexual behaviors of Spanish adolescents related to whether their parents were married or divorced. Participants were 342 boys and girls aged between 14 and 18 years. The sample provided confidential information about their sexual behavior and birth control methods. Significant differences were only found in percentages of adolescents who had engaged in mutual masturbation, intercourse, or oral sex, and who had practiced these sexual relations in the last six months, in both cases, they were higher when the parents had broken their marital relationship. Regarding adolescents of divorced parents, engaging in intercourse is more likely in older teenagers who live with a stepparent. Moreover, older adolescents who were younger when parents divorced and who live in a reconstituted family, have more sexual partners. These and other findings are discussed.     

Sociodemographic, clinical and outcome differences among anxiety disorders

The aims of this paper are to analyze differences in sociodemographic and clinical characteristics among the various anxiety disorders treated in a Psychology Clinic, and the results of treatment in each anxiety disorder. Data from 282 patients of University Psychology Clinic at the Complutense University of Madrid, who had at least one diagnosis of anxiety according to DMS-IV-TR criteria, were analyzed. The most frequent anxiety disorders were nonspecific anxiety disorder (19.1%) and social phobia (18.8%). Significant differences were observed according to sex (in all disorders, the percentage of women was significantly higher than that of men, except for obsessive-compulsive disorder). Unspecific anxiety disorder required a smaller number of assessment and treatment sessions, whereas obsessive-compulsive disorder required a greater number of sessions. There were no significant differences between the percentage of patients who completed treatment and dropout rates in specific phobia, general anxiety disorder and obsessive-compulsive disorder. Differences between epidemiological and clinical data are discussed.     

The multidimensional nature and multicultural validity of a new measure of social anxiety: the Social Anxiety Questionnaire for Adults

Much has been written about the situations most often feared by persons with social phobia, and several self-report measures are frequently used to assess such feared situations. However, it is not clear whether the situations feared by persons with social phobia form unidimensional or multidimensional factors. If these situations are multidimensional, reliance on a total score of feared situations would not reflect important differences between those dimensions. This research examined the multidimensional nature and multicultural validity of a newly developed instrument (the Social Anxiety Questionnaire for Adults [SAQ-A]) in two studies with a total of 539 patients diagnosed with social phobia and 15,753 nonpatients from 20 different countries. The structure (five clear and solid factors) and psychometric properties of the final instrument (the SAQ-A30) support the multidimensional nature of social anxiety and provide a new perspective in the assessment of social phobia.     

French Children’s Awareness of Gender Stereotypes About Mathematics and Reading: When Girls Improve Their Reputation in Math

Since 2000, surveys on academic achievement show gender inequalities in favor of girls in the school setting. The aim of the present study was to examine if gender stereotypes about academic abilities that are usually considered as fully demonstrated in the literature have to be updated. Three hundred ninety-eight French fifth graders from a medium-sized provincial town answered a questionnaire designed to examine, both with direct and indirect measures, if they hold different gender stereotypes concerning mathematics and reading depending on target’s age (children vs. adults). As expected, results showed that participants, regardless of their gender, were aware of a math-ability stereotype favorable to men when the stereotyped targets were adults. When the stereotyped targets were children and young adolescents, the math-ability stereotype was less clear. Participants believed that people think that girls succeed as well as boys in math. Concerning reading-ability, participants reported the “usual” stereotype favorable to females, regardless of the stereotyped target’s age (child or adult). Together these results suggest that academic gender stereotypes have to be reconsidered. The math-ability stereotype targeting children and favorable to both genders seems to show an improvement of the French girls’ reputation in mathematics. Moreover, the reputation of French boys in this domain seems to be poorer than reported in previous research.     

Influence of background on precision of 3D depth judgment tasks in a real environment

Presently, little is known about the effect of curved backgrounds against which the target stimulus is presented on precision in stereoacuity. The experiment analyzed the influence of stimulus orientation and 3D background configuration on stereoscopic vision. Participants were instructed to perform 3D visual alignment tasks on a modified version of the Howard-Dolman apparatus, whereupon precision in depth perception for different curved backgrounds (flat, black, concave, and convex) was evaluated. In addition, the influence of stimulus orientation (0 degrees, 45 degrees, and 90 degrees) on precision was examined. The findings revealed an underestimation in the perceived depth in all background configurations, indicating highest and lowest precision outcomes for convex and concave backgrounds, respectively. In addition, a significant interaction of background and orientation was found. It was concluded that, in a real environment, background local depth cues are integrated with target stimuli to contribute to depth perception.     

Effect of an aerobic training program as complementary therapy in patients with moderate depression

The aim of this study was to assess the effects of an aerobic training program as complementary therapy in patients suffering from moderate depression. 82 female patients weredivided into a group that received traditional pharmacotherapy (Fluoxetine 20 mg) and a group that received pharmacotherapy plus an aerobic training program. This program was carried out for eight consecutive weeks, three days per week, and included gymnastics, dancing, and walking. Depressive symptoms were measured with the Beck Depression Inventory and the ICD-10 Guide for Depression Diagnosis, both administered before and after treatments. The results confirm the effectiveness of the aerobic training program as a complementary therapy to diminish depressive symptoms in patients suffering from moderate depression.     

Deciding where to attend: priming of pop-out drives target selection

With attention and eye-movements humans orient to targets of interest. This orienting occurs faster when the same target repeats: priming of pop-out (PoP). While reaction times (RTs) can be important, PoP's real function could be to steer where to orient, a possibility underexposed in many current paradigms, as these predesignate a target to which to orient. In a novel procedure we intermixed pop-out trials (one oddball target, two identical distractors) with choice trials (one item of each kind) where observers freely chose an item to attend to. Pop-out trials strongly drove subsequent choice: observers typically chose the preceding target. Conversely, choice trials affected subsequent pop-out RTs. Conventional PoP measures correlated positively with our choice measures among observers, suggesting common mechanisms. Our results support PoP accounts centered on altered target priority, and underscore PoP's importance for visual exploration.     

Psychological variables in the control of brain-computer interfaces

BCI (Brain-Computer Interface) is a system that allows interaction between the human brain and a computer. It is based on analyzing electroencephalographic signals (EEG) and processing them to generate control commands. The study analyzed the possible influence of psychological variables, such as the imaginative kinesthetic capacity and anxiety, in relation to performance in a BCI. All participants (4 male and 19 female students) completed the questionnaires and carried out a session of BCI to control their EEG signals in a virtual setting of a car along a straight road. The group was divided into two subgroups according to their EEG signals or differential responses obtained in the left-right discrimination. Study results showed no significant differences in cognitive variables of imagination or in anxiety. By comparing the degree of participants' BCI control, a new quantitative parameter for comparing performances and making decisions in signal processing was found. The findings, the ongoing research process to refine the control of a BCI, and the interaction of psychological and computer procedures are discussed.     

Morphological awareness: development trends and patterns of evolution in kindergarten and primary education

We present a study that investigates changes in the acquisition and development of morphological awareness in children from 5 to 7 years old. This investigation was carried out on three separate occasions over two academic years, in which morphological awareness was assessed according to two levels. The data indicate an increase in the morphological awareness development from the kindergarten to primary education, verifying the acquisition in the first instance of the morphological judgment level and secondly, of morphological production level. It also generates a pattern of acquisition of the various parameters that make up morphology.
