Learning generalization in problem solving by a blue-fronted parrot (<Emphasis Type="Italic">Amazona aestiva</Emphasis>)

Pepperberg (The Alex studies: cognitive and communicative abilities of gray parrots. Harvard University Press, Cambridge;1999) showed that some of the complex cognitive capabilities found in primates are also present in psittacine birds. Through the replication of an experiment performed with cotton-top tamarins (Saguinus oedipus oedipus) by Hauser et al. (Anim Behav 57:565-582; 1999), we examined a blue-fronted parrot's (Amazona aestiva) ability to generalize the solution of a particular problem in new but similar cases. Our results show that, at least when it comes to solving this particular problem, our parrot subject exhibited learning generalization capabilities resembling the tamarins'.     

Free-association norms for the Spanish names of the Snodgrass and Vanderwart pictures.

The most frequent names in Spanish corresponding to a set of 247 pictures in the Snodgrass and Vanderwart (1980) norms were used as stimuli in a discrete free-association task. A sample of 525 Spanish-speaking participants provided the first word that came to mind for each of the verbal stimuli. Responses were organized according to frequency of production in order to prepare word-association norms for the set of stimuli.     

Psychologie communautaire en Amérique latine : trajectoire historique et enjeux actuels

The aim of this article is to describe the historical circumstances and the sociopolitical influences that gave rise to community psychology in Latin America. The presentation discusses the evolution of the discipline beginning in the late 1950s and elaborates on the historical, social and political influences that shaped its identity, including the context for the evolution of psychology as a scientific discipline and as a helping profession. Finally, two major and current challenges that community psychology faces in Latin America are discussed, namely the systematisation and evaluation of intervention and practice, and the empowerment of communities through real participation of its members.     

Gender Differences in the Representation of Violence on Spanish Television: Should Women be More Violent?

Gender differences in the representation of aggressors and victims are an important issue in the study of television violence in order to ascertain whether television contributes (and how) to reproduce or transform the traditional gender regime. Eighty-four hours of Spanish main TV broadcasting stations were randomly recorded during years 2000 and 2005. Variables related to the presentation of aggressors and victims and to the normative context of aggression were selected through content analysis. The results show the minimal presence of women in violent scenes. But women are also the victims of more serious violence. Paradoxically, women’s aggressions appear to have more positive consequences and to be less legitimized. The implications of these findings are discussed from a gender studies perspective.     

Effects of the dialectical behavioral therapy-mindfulness module on attention in patients with borderline personality disorder

It is known that patients with borderline personality disorder (BPD) show attention deficits and impulsivity. The main aim of this study was to explore the effects of Dialectical Behavioral Therapy-Mindfulness training (DBT-M), used as an adjunct to general psychiatric management (GPM), on attention variables in patients diagnosed with BPD. A second objective was to assess the relation of mindfulness formal practice on clinical variables. A sample of 60 patients with BPD was recruited. Forty of them were allocated to GPM + DBT-M treatment and the other 20 received GPM alone. At the termination of the mindfulness training, DBT-M + GPM group showed a significant improvement on commissions, hit reaction time, detectability scores from the CPT-II neuropsychological test, and also on the composite scores of inattention and impulsivity. Further, the more minutes of mindfulness practice were correlated to greater improvement in general psychiatric symptoms and affective symptomatology, but not in CPT-II measures. This is probably the first study so far assessing the effects of this single DBT module in patients with BPD. The results suggest a positive effect of such intervention on attention and impulsivity variables.     

Fibromyalgia in men and women: comparison of the main clinical symptoms

The prevalence of fibromyalgia (FM) in males is much lower than in women. Thus, current knowledge about the syndrome has been developed from research with women. The aim of the present study is to analyze whether FM manifestations differ as a function of sex. Two clinical groups with FM (21 males and 21 women) and a control group of healthy men (n= 21) participated in the study. Several aspects of pain, sleep, fatigue, psychopathology, emotional distress and functional impact of FM were evaluated with an algometer and questionnaires. The clinical groups showed a significantly greater impairment than the control group in all the self-report measures. However, the FM patients only showed significant differences in the sensibility threshold to the pain, which was lower in the women. In addition, the best predictor of the experience of pain in males was sleep quality, and in the women, catastrofying pain. Our results suggest that the most effective therapeutic strategies to control pain may be different for men and women.     

The role of self-guided training in the relationship between task conflict and innovation in virtual teams

This study was conducted to evaluate the moderating role of self-guided training in the relationship between task conflict and team innovation in synchronic computer-mediated communication (SCMC) teams. For this purpose, a laboratory study was carried out in which 26 teams were assigned to the training condition and 24 to the control condition. Results confirmed that SCMC teams develop a negative relationship between task conflict and innovation, but also revealed that self-guided training may slow these counterproductive effects down. Our study provides new evidence of the linear relationship between task conflict and team innovation in SCMC teams, extending previous research findings obtained in face-to-face teams to virtual context and suggest that self-guided training can be useful for virtual team innovation.     

Trial-based psychotherapy and the efficacy of trial-based thought record in changing unhelpful core beliefs and reducing self-criticism

IntroductionThe best prevention against relapse results when patients are taught to restructure negative core beliefs (CBs). Efficacy of the trial-based thought record (TBTR) in decreasing the credit given by patients to negative CBs and corresponding emotions was evaluated.MethodPatients (n = 166) were submitted to a simulation of a legal trial to assess their adherence to negative CBs and corresponding emotions after each cognitive therapy technique incorporated by TBTR. RESULTS: Significant reductions existed in percent values after the first and second defense attorney pleas, as well as after jury's verdict and initial preparation for the appeal (p < 0.001), relative to the investigation phase. Significant differences also emerged between the defense attorney's first and second pleas and between the defense attorney's second plea and jury's verdict, as well as preparation for the appeal (p < 0.001). There was no significant difference between percentages presented by patients submitted to TBTR used in the empty chair format relative to the conventional format. Similarly, there was no difference between outcomes, regardless of therapists' level of exposure to TBTR.ConclusionTBTR may help patients reduce attachment to negative CBs and corresponding emotions. Outcomes were significantly favorable regardless of the format use and therapists' level of exposure to TBTR.     

A mediation model of individual differences in attitudes toward affirmative actions for women

A mediation model of the relation between gender and attitudes toward affirmative action in favor of working women was tested. Four mediation variables were considered: perceived unfairness in the situation of working women, perceived threat to the non-designated group (men), self-esteem, and gender self-concept (masculinity and femininity). 192 women and 128 men, with differing occupations, participated. Gender affects individuals' attitudes toward affirmative actions for women, mediated by perceived unfairness in the situation of working women, perceived threat to the non-designated group, and feminine self-concept. Implications for research and practice are discussed.
