Schizotypal experiences and depressive symptoms are quite common among adolescents, and have been considered as risk markers for schizophrenia-spectrum and mood disorders. The main goal of the present study was to analyze the relationship between schizotypal experiences and depressive symptoms in a community sample of non-clinical adolescents. The sample comprised a total of 1653 participants, 794 male (48%), with an average age of 15.94 years (SD = 1.23). Results showed that schizotypal traits and depressive symptoms were closely related at a subclinical level. Canonical correlation analysis indicated that the two sets of variables shared approximately 48% of the variance. The study of the dimensionality underlying the subscales of the self-reports revealed the presence of three components, namely: Depressive, Anhedonia and Reality Distortion. These results are convergent with previous studies conducted in both clinical and non-clinical samples, indicating overlap between schizotypal experiences and depressive symptoms. 相似文献

Epidemiological studies usually show a link between personality disorders and addictions. Dimensional models of personality, such as that of Cloninger, are able to diagnose and discriminate between transient dysfunctional behavior styles and relatively more stable traits. Certain brain areas have been proposed, as trait locations, based on their activation. This paper explores differences in personality traits among a sample of alcohol abusers (N= 95) and a control group of non-clinical population (N= 95), matched in sociodemographic variables, using the TCI-R-67 and the FrSBe-Sp. It is hypothesized that such differences are associated with frontal symptomatology. The existence of different subgroups of addicts based on certain combinations of traits is also analyzed. Results showed significant differences in two temperament traits (Novelty Seeking and Harm Avoidance) and a characterial trait (Self-Direction). We also found a correlation with a large effect size between these traits and frontal symptomatology. Cluster analysis classified the participants into several subtypes with different combinations of traits that matched diverse frontal symptomatology. Possible neurobiological explanations of these differences and their importance in the clinical practice are discussed. 相似文献

Although research on the prevention of drug use has shown that the effectiveness of programs depends partly on who applies them, the results of studies designed to clarify this issue are contradictory. This study compared the effects on smoking, in the short and medium term, of the implementation of two school-based prevention programs, depending on the type of applicator. The sample was made up of 200 seventh-grade students distributed among five experimental conditions: four of intervention, in which the programs were implemented by teachers from the school or by external psychologists, and one of control. The results show that teachers applying the Barbacana program and psychologists applying the Construyendo Salud (Building Health) program succeeded in reducing the incidence of cigarette smoking (BR-teachers 15%; C.S-psychologists 5%) and strengthening attitudes against smoking. An interaction effect between type of program and type of applicators was clearly observed. 相似文献

Cognitive deficits in fibromyalgia may be specifically related to controlled processes, such as those measured by working memory or executive function tasks. This hypothesis was tested here by measuring controlled temporal preparation (temporal orienting) during a response inhibition (go no-go) task. Temporal orienting effects (faster reaction times for targets appearing at temporally attended vs. unattended moments) and response inhibition were impaired in fibromyalgia compared to the control group. It is concluded that frontal networks underlying attentional control (temporal orienting and response inhibition) can be a dysfunctional neurocognitive mechanism in fibromyalgia. 相似文献

The relative position priming effect is a type of subset priming in which target word recognition is facilitated as a consequence of priming the word with some of its letters, maintaining their relative position (e.g., csn as a prime for casino). Five experiments were conducted to test whether vowel-only and consonant-only subset primes contribute equally to this effect. Experiment 1 revealed that this subset priming effect emerged when primes were composed exclusively of consonants, compared with vowel-only primes (csn-casino vs. aia-animal). Experiment 2 tested the impact of letter frequency in this asymmetry. Subset priming effects were obtained for both high- and low-frequency consonants but not for vowels, which rules out a letter frequency explanation. Experiment 3 tested the role of phonology and its contribution to the priming effects observed, by decreasing the prime duration. The results showed virtually the same effects as in the previous experiments. Finally, Experiments 4 and 5 explored the influence of repeated letters in the primes on the magnitude of the priming effects obtained for consonant and vowel subset primes (iuo-dibujo and aea-madera vs. mgn-imagen and rtr-frutero). Again, the results confirmed the priming asymmetry. We propose that a functional distinction between consonants and vowels, mainly based on the lexical constraints imposed by each of these types of letters, might provide an explanation for the whole set of results. 相似文献

We tested hypotheses concerning the developmental roots of becoming the "weak-link" (less committed) partner in adult romantic relationships and the associations between partners' absolute and relative levels of commitment and dyadic outcomes. We examined 78 target 20- to 21-year-olds who were involved in a romantic relationship and who had been studied since birth. As predicted, people who received lower-quality support from caregivers in toddlerhood or who were less able to resolve conflicts with a best friend in midadolescence were more likely to become the weak-link partner in a romantic relationship at age 20 to 21. Furthermore, lower commitment on the part of the weak-link partner coupled with greater discrepancy in commitment between partners predicted a greater likelihood that the couple would display hostility (rated by observers) during a videotaped conflict-resolution task when they were 20 to 21 years old. These findings are discussed from developmental and dyadic perspectives. 相似文献

The aim of this study was twofold. The first aim was to study the effect of an intervention combining team feedback and guided reflexivity on virtual teams' affective outcomes. The second was to examine the mediating role of perceived social loafing in this relationship. An experimental laboratory study was carried out with 54 teams randomly assigned to an experimental condition or a control condition. Results showed that this intervention had an effect on satisfaction with the result, but not on group cohesion and satisfaction with the team. Moreover, perceived social loafing fully mediated the effect of this intervention on group cohesion and partially mediated its effect on satisfaction with the team and the result. 相似文献

The authors' aim was to investigate the effects of continuous transcranial direct current stimulation (tDCS) combined with virtual reality training on static and functional balance in children with cerebral palsy (CP). Twenty children with CP (6 girls and 14 boys; M age = 7 years 6 months ± 2 years) were randomly allocated to two groups. The experimental group received active tDCS and the control group received sham stimulation during the 10 sessions of virtual reality mobility training protocols. The children were evaluated on 3 occasions (preintervention, postintervention, and 1-month follow-up). Static balance was evaluated using a force plate under 4 conditions: feet on force plate with (a) eyes open and (b) with eyes closed, and feet on foam mat with (c) eyes open and (d) with eyes closed. Functional balance was evaluated using the Pediatric Balance Scale and the Timed Up and Go Test. The analyses demonstrated statistically significant postintervention and follow-up effects favoring the experimental group over the control group with regard to the Pediatric Balance Scale, Timed Up and Go Test, and area of oscillation of the center of pressure when standing on the force plate with eyes open. The present findings suggest that tDCS can potentiate the effects of virtual reality training on static and functional balance among children with CP. 相似文献

Ambivalent sexism has served to justify and maintain patriarchy and traditional gender roles characterized by inequality and male domination in the intimate partner violence (IPV) literature; according to the Moral Foundation Theory (MFT) there are two specific moral foundations related to inequality and domination: fairness and authority. We connect these separate fields arguing that sexist attitudes can be related to specific patterns of endorsement of the five moral foundations. Our hypothesis is that ambivalent sexism in men convicted of violence against the partner may be rooted in at least these two moral foundations, and that at least these two moral foundations may also serve to predict intention to change the violent behavior against the partner. Controlling for political orientation, the results show that benevolent sexism correlates positively with the authority foundation; and hostile sexism correlates negatively with the fairness foundation. Both foundations contribute to explaining the two dimensions of ambivalent sexism (benevolent and hostile) and only the fairness foundation predict intention to change the violent behavior against the partner. New treatment approaches could be designed to increase moral concerns about fairness and to reduce moral concerns about authority in people who, at least, have once used violence against their partners. 相似文献
