Organización y mantenimiento de un estabulario de ratas para la investigación en psicología (I)

Resumen

En este trabajo se argumenta la necesidad de disponer de un estabulario propio en los centros donde se lleva a cabo investigación básica en Psicología, para asegurar unas condiciones óptimas de los animales y, así, obtener una alta fiabilidad en los resultados de la experimentación. Hemos dividido el trabajo en dos partes: en esta primera se dan las principales orientaciones y normas para organizar y mantener adecuadamente un estabulario de ratas, referidas concretamente a la infraestructura, sistemas de apareamiento, condiciones psicofísicas, higiene y, finalmente, se dan algunas características fisiológicas de la rata Wistar.     

Organización y mantenimiento de un estabulario de ratas para la investigación en psicología (II)

Resumen

El presente articulo, segunda parte de Organización y mantenimiento de un estabulario de ratas para la investigación en Psicología (I). Trata de la rata como fuente de variación en los experimentos psicológicos, de cómo puede el psicólogo inferir que los sujetos de un experimento están en buenas condiciones. Trata también de cómo conseguir esas buenas condiciones en el sujeto experimental a través de dietas correctas; se hace un repaso a las enfermedades carenciales más notorias. Finalmente se explican métodos estandarizados para privar de aliment os o bebida, métodos de administración de fármacos y algunas alternativas para controlar el estrés en la rata de estabulario.     

Individual and parental factors related to meaning in life among Hungarian minority adolescents from Romania

Understanding how adolescents achieve meaning in life has important implications for their psychological development. A social cognitive model of meaning development was tested by assessing psychological (self‐efficacy, self‐regulation and social comparison) and parental (parental responsiveness, demandingness, and social support) variables in a sample of 1944 adolescents (aged 15–19 years; 47.8% males) from secondary schools of the Middle Transylvanian Region, Romania. Both psychological and parental factors were significantly related to meaning in life. For both boys and girls, self‐efficacy, self‐regulation, and maternal responsiveness related positively with meaning in life, and paternal demandingness related inversely to meaning in life. However, social comparison related positively to meaning only among boys, and paternal responsiveness related positively to meaning only among girls. Results point to a possible meaning‐supporting role played by social cognitive variables, as well as parental autonomy support. The gender differences observed here suggest that existing theories of meaning development may need to be elaborated to include family of origin and gender.     

Predictors of healthcare resource use in fibromyalgia

This work identifies which psychosocial, clinical and perceived health status factors predict health-resource use in Fibromyalgia (FM), considering the patients' assistance level. Participants were 315 FM patients from Primary Care (PC: n=101) and Rheumatology Services (RS: n=214). Stepwise regression analysis showed that self-efficacy variables were significant predictors of medication intake in PC, and, along with Illness-focused coping, of the health service use. In RS, perceived health status was the best predictor of medication intake. In any case, Pain intensity significantly predicted the use of health resources. These data offer a new perspective for intervention in these patients, taking into account the level of assistance.     

The Long Journey to Becoming an Emancipated Woman and a Relational Psychotherapist

This article contains a biography of the author, taking into consideration the cultural landscape in which she was immersed all along. It also shows how her search for an identity and a position in the world shaped her orientation, first to feminism and then to psychotherapy. Beginning with her belonging to Orbach’s self-help groups and evolving to a feminist and psychoanalytically oriented psychotherapist, she later became a bioenergetic analyst only to join the relational turn in psychoanalysis after having met Jessica Benjamin in 2002 and having published a number of papers to deconstruct classical psychoanalytic thinking with the help of Judith Butler, Nancy Chodorow, Emilce Dio Bleichmar, and many others.     

Semantic Processing of Foveally and Parafoveally Presented Words in a Lexical Decision Task

Using a lexical decision task in which two primes appeared simultaneously in the visual field for 150 msec followed by a target word, two experiments examined semantic priming from attended and unattended primes as a function of both the separation between the primes in the visual field and the prime-target stimulus-onset asynchrony (SOA). In the first experiment significant priming effects were found for both the attended and unattended prime words, though the effect was much greater for the attended words. In addition, and also for both attention conditions, priming showed a tendency to increase with increasing eccentricity (2.3°, 3.3°, and 4.3°) between the prime words in the visual field at the long (550 and 850 msec) but not at the short (250 msec) prime-target SOA. In the second experiment the prime stimuli were either two words (W-W) or one word and five Xs (W-X). We manipulated the degree of eccentricity (2° and 3.6°) between the prime stimuli and used a prime-target SOA of 850 msec. Again significant priming was found for both the attended and unattended words but only the W-W condition showed a decrement in priming as a function of the separation between the primes; this decrement came to produce negative priming for the unattended word at the narrow (2°) separation. These results are discussed in relation to the semantic processing of parafoveal words and the inhibitory effects of focused attention.     

Individual and group CBT and IPT for Puerto Rican adolescents with depressive symptoms

This study compared individual (I) to group (G) formats of cognitive-behavioral therapy (CBT) and interpersonal psychotherapy (IPT) for the treatment of depression in adolescents. One hundred and 12 Puerto Rican adolescents were randomized to four conditions (CBT-I, CBT-G, IPT-I, IPT-G). Participants were assessed at pretreatment and posttreatment with structured interviews to establish diagnosis and with self-report measures to assess treatment outcome. The results suggest that CBT and IPT are robust treatments in both group and individual formats. However, CBT produced significantly greater decreases in depressive symptoms and improved self-concept than IPT. The implications of these findings are discussed.     

Relationships among goal orientations, motivational climate and flow in adolescent athletes: differences by gender

The purpose of this investigation was to examine the relationships among perceived motivational climate, individuals' goal orientations, and dispositional flow, with attention to possible gender differences. A sample of 413 young athletes, ages 12 to 16 years, completed the Perceived Motivational Climate in Sport Questionnaire-2 (PMCSQ-2) and Perception of Success Questionnaire (POSQ), as well as the Dispositional Flow Scale. Task orientation was positively and significantly related to a perceived task-involving motivational climate and to the disposition to experience flow in the sport. Ego orientation was positively and significantly associated with a perceived ego-involving motivational climate and with dispositional flow. The perceptions of task-involving and ego-involving motivational climates were positively and significantly linked to general dispositional flow. Multiple regression analysis indicated that both task and ego goal orientations and perceived task- and ego-oriented climates predicted dispositional flow. Males displayed a stronger ego orientation, and were more likely to report that they participated in an ego-oriented climate, than did females. To the contrary, the females were more likely to perceive a task-oriented climate than did the males. No meaningful differences were found between males and females in general dispositional flow.     

Comparative analysis of the perception of school violence in teachers, pupils, and families

The main aim of the present study is to analyze the opinion of pupils, families and teachers in four European countries (Spain, Hungary, Austria and the Czech Republic) on the prevalence of violent behavior and other problematic aspects related to coexistence in schools, and on the way in which individuals are personally affected by them. For this purpose, a single instrument was used. From the results obtained it emerges, first of all, that there are significant differences depending on who is analyzing the school problems. Generally, families perceive the problems analyzed as less common and feel less affected by them personally. Hungary was considered to be the country with the lowest levels of school violence. Pupils indicate their concern about the high levels of lack of motivation or boredom, whilst teachers are more preoccupied about the serious problems of coexistence, due in particular to the presence or use of weapons and drugs and to intercultural conflicts.
