Recent studies point to a major role for alpha2-containing GABA-A receptors in modulating anxiety. However, the possible implication of GABA-A receptors containing the alpha3 subunit on anxiety is less known. The aim of this study was to examine the effects of SB-205384 (0.5-4 mg/kg, i.p.), an alpha3 subunit positive modulator of GABA-A receptor, on anxiety tested in the elevated plus-maze in male mice, using classical and ethological parameters. Mice treated with SB-205384 showed an increase in the frequency of entries and the time spent in open arms, as well as a reduction in the time spent in closed arms, as compared with the control group. A notable increase of "head-dipping" unprotected and a reduction of "stretched-attend posture" protected was also evident. These findings indicate that SB-205384 exhibits an anxiolytic-like profile in the elevated plus-maze test, suggesting that GABA-A receptors which contain the alpha3 subunit might be involved in regulation of anxiety. 相似文献

The aim of the present work is to evaluate the efficacy of a program entitled "Prevention of child sexual abuse" the first structured program in Spain designed to prevent such risks. With this purpose, we carried out a study of 382 minors with ages ranging between 8 and 12 years. The result s show that the program has a very positive impact, increasing the awareness of the minors about this type of risk and improving their skills for coping with a possible event of sexual abuse. The efficacy of the program is also apparent, at the level of secondary prevention, in that it increased the likelihood that the children would reveal such events. Finally, exploration of the possible adverse effects of the program showed that the negative effects observed by parents and educators are negligible. 相似文献

Lexical bias is the tendency for phonological errors to form existing words at a rate above chance. This effect has been observed in experiments and corpus analyses in Germanic languages, but S. del Viso, J. M. Igoa, and J. E. García-Albea (1991) found no effect in a Spanish corpus study. Because lexical bias plays an important role in the debate on interactivity in language production, the authors reconsidered its absence in Spanish. A corpus analysis, which considered relatively many errors and which used a method of estimating chance rate that is relatively independent of total error number, and a speech-error elicitation experiment provided converging evidence for lexical bias in Spanish. The authors conclude that the processing mechanisms underlying this effect hold cross-linguistically. 相似文献

This study investigated the trait emotional intelligence (trait EI or trait emotional self‐efficacy) profiles of 512 students from five university faculties: technical studies, natural sciences, social sciences, arts, and humanities. Using the Trait Emotional Intelligence Questionnaire, it was hypothesised that (a) social sciences would score higher than technical studies in Emotionality, (b) arts would score higher than technical studies in Emotionality, (c) arts would score lower than technical studies in Self‐control, and (d) there would be an interaction between gender and faculty, whereby female students would score higher than male students within the social sciences only. Several other exploratory comparisons were also performed. Results supported hypotheses (a), (b), and (d), but not hypothesis (c), although the differences were in the predicted direction. 相似文献

The existence of a close relation between personality and drug consumption is recognized, but the corresponding causal connection is not well known. Neither is it well known whether personality exercises an influence predominantly at the beginning and development of addiction, nor whether drug consumption produces changes in personality. This paper presents a dynamic mathematical model of personality and addiction based on the unique personality trait theory (UPTT) and the general modelling methodology. This model attempts to integrate personality, the acute effect of drugs, and addiction. The UPTT states the existence of a unique trait of personality called extraversion, understood as a dimension that ranges from impulsive behaviour and sensation‐seeking (extravert pole) to fearful and anxious behaviour (introvert pole). As a consequence of drug consumption, the model provides the main patterns of extraversion dynamics through a system of five coupled differential equations. It combines genetic extraversion, as a steady state, and dynamic extraversion in a unique variable measured on the hedonic scale. The dynamics of this variable describes the effects of stimulant drugs on a short‐term time scale (typical of the acute effect); while its mean time value describes the effects of stimulant drugs on a long‐term time scale (typical of the addiction effect). This understanding may help to develop programmes of prevention and intervention in drug misuse. 相似文献

This study examined whether the sociocultural context moderates the relationship between families' expressed emotion (EE) and clinical outcomes in schizophrenia. In a sample of 60 Mexican American caregivers and their ill relatives, we first assessed whether EE and its indices (criticism, emotional overinvolvement [EOI], and warmth) related to relapse. Second, we extended the analysis of EE and its indices to a longitudinal assessment of symptomatology. Last, we tested whether bidimensional acculturation moderated the relationship between EE (and its indices) and both relapse and symptom trajectory over time. Results indicated that EOI was associated with increased relapse and that criticism was associated with increased symptomatology. Additionally, as patients' Mexican enculturation (Spanish language and media involvement) decreased, EE was increasingly related to relapse. For symptomatology, as patients' U.S. acculturation (English language and media involvement) increased, EE was associated with increased symptoms longitudinally. Our results replicate and extend past research on how culture might shape the way family factors relate to the course of schizophrenia. 相似文献

A multiple baseline across settings was used to evaluate the effects of differential reinforcement of alternative behavior, nonremoval of the fork ( Hoch, Babbitt, Coe, Krell, & Hackbert, 1994 ), and stimulus fading on consumption of food rejected previously. The study was conducted in two separate settings, and caregivers were trained in the intervention technique to increase generalization to natural settings. Food variety increased in both settings. 相似文献

In January of 2007, freezing temperatures destroyed citrus and vegetable crops in California. By May 2007, more than 9,000 freeze‐related unemployment applications had been filed. Through face‐to‐face interviews, this study documents the experience of 63 farmworkers to find out how they survived the freeze and accessed services. Findings revealed that more than half of the interviewees did not seek benefits from the governmental One‐Stop centers set up to help them. Less than 10% of interviewees stated the benefits had covered their needs. Creating simple, nonbureaucratic guidelines for assisting affected individuals emerged as a need. 相似文献

Roy Sorensen has argued that a certain technical use of quotation marks to name the empty string supports a revised version
of Davidson’s theory of quotation. I point out that Sorensen’s considerations provide no support for Davidson’s original theory,
and I show that at best they support the revised Davidsonian theory only to the same extent that they support a simpler revised
version of a Tarskian theory. 相似文献

Heuristics and cognitive biases can occur in reasoning and decision making. Some of them are very common in gamblers (illusion of control, representativeness, availability, etc.). Structural characteristics and functioning of games of chance favor the appearance of these biases. Two experiments were conducted with nonpathological gamblers. The first experiment was a game of dice with wagers. In the second experiment, the participants played two bingo games. Specific rules of the games favored the appearance of cognitive bias (illusion of control) and heuristics (representativeness and availability) and influence on the bets. Results and implications for gambling are discussed. 相似文献
