Psychology in the Spanish scientific domain through categories cocitation of Journal Citation Report 1990-2005

This work aims to reveal some aspects of the scientific domain of Psychology, in the context of the internationally visible Spanish science in the databases of the Citation Index of The Institute for Scientific Information (ISI), which is represented by a map. We used the methodology of cocitation of thematic categories (JCR-Thompson Scientific), with which we obtained a representation of the scientific activity. The resulting map allowed us to focus on the area of Psychology, whose representation acts as database for the analysis of this discipline in the scientific field with international visibility. This study offers an empirical view of the underlying structure of Spanish Psychology. This is important because most scientists have an intuitive idea of this structure, but this may or may not be real. This way, we present a global vision of the entire discipline that favours its objective analysis as a function of scientists' behaviour as it affects their patterns of communication through the established formal channels.     

Differential role of the hippocampal endocannabinoid system in the memory consolidation and retrieval mechanisms

CB1 cannabinoid receptors are abundantly expressed in the brain, with large concentrations present in the hippocampus, a brain structure essential for memory processing. In the present study, we have investigated the possible modulatory role of the endocannabinoid system in the dorsal hippocampus upon the different phases of memory processing of an aversive task. AM251, a selective antagonist of CB1 receptors, and anandamide, an endogenous agonist of cannabinoid receptors, were bilaterally infused into the dorsal hippocampus of male Wistar rats either before training, immediately after training, or before test in the step-down inhibitory avoidance (IA) task. Results showed that pre-training infusion of CB1 drugs did not influence the acquisition of the task. In contrast, post-training infusion of the CB1 antagonist disrupted while the antagonist facilitated memory consolidation of IA. The post-training results demonstrate that memory consolidation depends on the integrity of the endocannabinoid system in the CA1 region of the dorsal hippocampus. While we still have no direct proof of endocannabinoids released there after an aversive task such as IA, these results suggests that (a) AM251 acts blocking the binding of endogenously released cannabinoids and (b) exogenously supplemented anandamide may be adding its contribution to the action of the endogenously released pool. Considering our data and the higher density of CB1 receptors present in the GABAergic interneurons, we propose them as the putative target of the endocannabinoid modulation of memory, a hypothesis that needs to be proven. In addition, pre-test infusion of the CB1 receptor antagonist facilitated while infusion of the agonist did not affect memory retrieval of IA. The completely opposite action of the same drug upon memory at the post-training (consolidation) and pre-test (recall) contexts suggests that some durable change took place in the CA1 region during the consolidation process that modified the logical attributes of the pharmacological response, i.e., the drug response changed from memory disruption to memory facilitation. A similar phenomenon was previously described by us in the M4 cholinergic muscarinic subsystem in the hippocampus for the same task (Diehl, F., Fürstenau, L. O., Sanchez, G., Camboim, C., de Oliveira Alvares, L., Lanziotti, V. B., et al. (2007). Facilitatory effect of the intra-hippocampal pretest administration of MT3 in the inhibitory avoidance task. Behavioral Brain Research, 177(2), 227-231), but the biological nature of such change in the local neural circuitry remains to be investigated.     

Family perception of the process of organ donation. Qualitative psychosocial analysis of the subjective interpretation of donor and nondonor families

Family perception of organ donation has been explored by numerous authors using statements by the people who decided whether or not to donate the organs of a relative in a situation of brain death. Within this tradition, in this work, we analyze the discourse of six families who granted permission for organ donation and three who refused. We describe the process-based interpretation of this experience and identify psychosocial variables and processes that further our understanding of the decision finally adopted. We have identified two heuristics that guide family decision when organ donation is requested: the explicit or inferred will of the deceased and family attitudes to organ donation and transplant. It is postulated that the interaction of these two factors explains a large amount of the decisions made. We also hypothesize that a marked discrepancy between these two factors increases the importance of other aspects, especially the role of the transplant coordinator and of other healthcare personnel. These results support, at a social level, the implementation of transplant promotion programs; and at a healthcare level, the combined use of techniques of crisis intervention and attitude change.     

Virtual reality and acrophobia: one-year follow-up and case study.

We present a study with 10 subjects being exposed to three sessions of simulated heights in a virtual reality (VR) system. Among the participants we highlight a 66-year-old man blind in his left eye. The participants show significant progress in anxiety, avoidance, and behavior measurements when confronted with real height circumstances. The results obtained 1 year later at follow-up are statistically significant in the Behavioral Avoidance Test (BAT) and the Attitudes Toward Heights Questionnaire (ATHQ), but not the Acrophobia Questionnaire (AQ).     

Increasing physical activity in children 8 to 12 years old: experiences with VERB Summer Scorecard

Interventions which facilitate physical activity of youth are vital for promoting community health and reducing obesity. This study assessed the results of a community-driven program, VERB Summer Scorecard, as knowledge of exposure to and awareness of community-based interventions for physical activity among youth could inform design and implementation of such interventions. A total of 2,215 youth ages 8 to 12 years responded to a survey about physical activity. Ordinal logistic regression suggested that youth who participated in this program were 1.73 times (95% CI = 1.41, 2.11) more likely to report high physical activity than nonparticipating youth 9 mo. after the intervention's first full-scale application. The program appeared to appeal more to girls than boys. Such results are encouraging for use in communities.     

When Contact Correlates with Prejudice: Adolescents’ Romantic Relationship Experience Predicts Greater Benevolent Sexism in Boys and Hostile Sexism in Girls

The present research examines how romantic relationship experience and age predict ambivalent sexism in adolescents. We measured sexist beliefs and romantic relationship experience in a large sample of Spanish adolescents (N?=?1447), ranging from 12 to 19 years of age. Consistent with prior research, age predicted less sexist beliefs. Controlling for the effects of age, relationship experience predicted increased hostile sexism in girls and increased benevolent sexism in boys. Additionally, younger boys (12–14 years) with greater relationship experience tended to endorse hostile sexism more strongly. The general decline in sexism over the course of adolescence masks a contrasting effect of romantic experience, which suggests that heterosexual adolescents’ desire to attract romantic partners may foster, rather than reduce, sexism.     

Social Perception of Rape Victims in Dating and Married Relationships: The Role of Perpetrator’s Benevolent Sexism

Two hypothetical scenario studies examined how situational, perpetrator, and observer factors affect blame towards rape victims. In Study 1, Spanish high school students (N?=?206) read about a rape committed by a boyfriend or husband who was described as benevolently sexist or not. Study 2 (N?=?201 British college students) replicated and extended Study 1 by adding a condition in which the rapist was described as a hostile sexist. In both studies, participants’ benevolent sexism scores predicted more victim blame when the rapist was described as a husband (but not a boyfriend) who held benevolently sexist attitudes. Study 2 showed that participants’ hostile sexism scores predicted more victim blame when the rapist was described as a hostile sexist.
