The study examined the relationship between ethnic identity and risky health behaviors in 1,892 Mexican-American students (M age= 14.6, SD= 1.35; 50.3% male) in South Texas. The Ethnic Identity Scale assessed ethnic identity and questions from the Youth Risk Behavior Survey measured risky health behaviors (mixed use of alcohol and drugs, heavy drinking, driving under the influence, regular marijuana use, regular cigarette smoking, lack of regular exercise, not eating breakfast regularly, and carrying a gun or knife to school). Logistic regression tested the relationships between ethnic identity and report of risky health behaviors controlling for potential confounders (sex, free school lunch status, grade, and self-reported school grade). Adjusted odds ratio (AOR) and confidence intervals were calculated. Results indicated that being associated with Mexican-American cultural identity was significantly associated with a decreased mixed use of alcohol and drugs (AOR= .97), heavy drinking (AOR= .98), and regular marijuana use (AOR= .97). A stronger ethnic identity was protective against engaging in risky health behaviors among these Mexican-American adolescents.  相似文献

There are few empirical studies on the issues of psychology graduate students beyond dissertation research. Data from a sample of 65 psychology graduate students were analyzed to explore how stress relates to self-esteem, mood, and daily habits (eating, sleeping, smoking, exercise, and alcohol consumption). The results suggest that sleep patterns, exercise habits, and negative mood were significant correlates and predictors of stress. Findings prompt further investigation of the effects of the stress on psychology graduate students, which might aid in developing interventions leading to increased productivity, satisfaction, and global well-being for both graduate students and faculty.  相似文献

In this paper, the most frequent personality disorders related to pathological gambling are described. A sample of 50 pathological gamblers, who were assessed with the MCMI-II before treatment, and of 50 normative subjects from general population with the same demographic features (age, sex and socioeconomic level) was selected. According to the results, the 40% of clinical sample (versus the 14% of normative sample) showed at least one personality disorder. The most prevalent one was the Narcissistic (32%), followed by the Antisocial and Passive-Aggressive (16% each one of them). Furthermore, the gamblers with personality disorders presented an average of 2.2 disorders and tended to be more impulsive. Likewise pathological gamblers abused of alcohol, showed a mild anxiety and were not so adapted to everyday life as much as the control group. Finally, implications of this study for clinical practice and future research in this field are commented upon.  相似文献

We present in this paper the sportive cooperation as a theoretical framework for the teams' dynamics, and as an alternative to others theories, specially the sportive cohesion. This theory has a double basis: 1) The rational and utilitarist decision taking upon the personal cooperation or not, with the team's goal, based on the internal teammates interaction, and the environmental stimuli; and 2) A personal, and more stable, disposition to cooperate, despite the possibility of obtain any counterparts for this behavior. From this framework, we have build--in a three phase process--a questionnaire addressed to evaluate the sportive cooperation. The final version--composed of 15 items with standard psychometric propierties--shows two kinds of factors. First, we have two dispositional, traitlike, factors: The Conditional cooperation, and the Unconditional cooperation. Second, we have three situational factors: the Cooperation with the Coach, with the teammates, and the Cooperation outside the game and the training. Lastly, we discuss the maining of this theory respect to the sportive team's dynamics, and its relevance for the applied psychology, both for the evaluation and the interventions on the teams.  相似文献

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

Three experiments investigated the effects of two variables -selective attention during encoding and delay between study and test- on implicit (picture fragment completion and object naming) and explicit (free recall and recognition) memory tests. Experiments 1 and 2 consistently indicated that (a) at all delays (immediate to 1 month), picture-fragment identification threshold was lower for the attended than the unattended pictures; (b) the attended pictures were recalled and recognized better than the unattended; and (c) attention and delay interacted in both memory tests. For implicit memory, performance decreased as delay increased for both attended and unattended pictures, but priming was more pronounced and lasted longer for the attended pictures; it was still present after a 1-month delay. For explicit memory, performance decreased as delay increased for attended pictures, but for unattended pictures performance was consistent throughout delay. By using a perceptual object naming task, Experiment 3 showed reliable implicit and explicit memory for attended but not for unattended pictures. This study indicates that picture repetition priming requires attention at the time of study and that neither delay nor attention dissociate performance in explicit and implicit memory tests; both types of memory require attention, but explicit memory does so to a larger degree.  相似文献

Study 1: The aim of this study was to analyze in persons detoxified of heroin, compensatory conditioned responses (CCRs) that are opposite to the unconditioned physiological, and subjective effects that are induced by this substance. The procedure consisted in presenting slides with images of neutral stimuli (NSs) and conditioned stimuli (CSs) of heroin to both non-addicted and detoxified addicted persons. The evaluated responses were heart rate (HR) and desire for heroin (DH). Study 2: The aim was to facilitate the emission of mimetic conditioned responses (MCRs) to the unconditioned physiological, and subjective effects of heroin in detoxified heroin addicts. Three different stimulus series were manipulated: SA, during which the participant remained alone; SB, administration of a needle prick given by the researcher; SC, performance of the "pump" ritual without drug by the participants. The responses measured were HR and DH. The results of both studies are considered, respectively, to be indicators of compensatory and mimetic conditioned responses.  相似文献

abstract The possibility that organ sales by living adults might be made legal is morally distressing to many of us. However, powerful arguments have been provided recently supporting legalisation (I consider two of those arguments: the Consequentialist Argument and the Autonomy Argument). Is our instinctive reaction against a market of organs irrational then? The aim of this paper is not to prove that legalization would be immoral, all things considered, but rather to show, first, that there are some kinds of arguments, offered in favour of legalisation, that are, in an important sense, illegitimate, and second, that even if legalisation might not be wrong all things considered, there are good reasons for our negative moral intuitions. Moreover, identifying these reasons will help highlight some features of moral decisions in non‐ideal situations, which in turn might be relevant to some other moral or policy choices.  相似文献
