The authors examined modulation of the simple act of word naming induced by the conflict arising when that task competes with color naming in a task-switching paradigm. Subjects alternated between naming a word printed in black and naming the color of a stimulus in 2 conditions. In the incongruent condition, the colored stimulus was an irrelevant word generating conflict, and in the neutral condition, color was carried by a row of asterisks. Subjects took substantially longer to name a word printed in black in the incongruent condition, implying a form of suppression. This modulation of the word-naming response was adaptive in that it led to more efficient color naming. The modulation effect was replicated using phoneme detection instead of word naming but not with lexical decision or visual comparison, implicating a phonological encoding process.  相似文献

Existing research on children with lesbian parents is limited by reliance on volunteer or convenience samples. The present study examined the quality of parent-child relationships and the socioemotional and gender development of a community sample of 7-year-old children with lesbian parents. Families were recruited through the Avon Longitudinal Study of Parents and Children, a geographic population study of 14,000 mothers and their children. Thirty-nine lesbian-mother families, 74 two-parent heterosexual families, and 60 families headed by single heterosexual mothers were compared on standardized interview and questionnaire measures administered to mothers, co-mothers/fathers, children, and teachers. Findings are in line with those of earlier investigations showing positive mother-child relationships and well-adjusted children.  相似文献

This article reports the results of a survey of Canadian Chinese pastors (N 20) regarding their experiences and attitudes related to pastoral counseling. It identifies common concerns encountered during pastoral counseling, as well as key areas of church concerns. Results of the survey indicate that pastoral counseling may be more important than is currently recognized by Chinese pastors, particularly in key areas of marriage, family life, and general relationship issues. The authors discuss possible implications of the survey relative to training and equipping Chinese pastors to engage more in pastoral counseling as an integral part of their parish ministry.  相似文献

This investigation predicted adolescents' delay of intercourse onset from attitudes, social norms, and self-efficacy about refraining from sexual intercourse. Age, gender, ethnicity, and parental education were also examined as predictors and moderators of the relationships among the 3 psychosocial determinants and onset. The participants (N = 827), part of a cohort initially surveyed in the 9th grade, reported at baseline that they had never engaged in intercourse. The multivariable proportional hazards regression model suggested that adolescents with more positive attitudinal and normative beliefs, as well as those with a parent who graduated from college, were less likely to engage in intercourse in the follow-up period (up to approximately 2 years). Interventions that include an objective to delay onset may benefit from addressing psychosocial determinants, especially attitudes and norms about sexual intercourse.  相似文献

This study investigates the effects of culture, BATNA (best alternative to a negotiated agreement), outcome scales, and mediation on negotiation outcomes. Six hundred three subjects from 2 countries (288 from Hong Kong and 315 from the United States) participated in 2-party negotiations that were either mediated or observed by a third party. In these negotiations, the Hong Kong negotiators obtained higher joint outcomes than did their U.S. counterparts. Also, in both Hong Kong and the United States, negotiators with a high BATNA obtained larger individual outcomes than did those with a low BATNA. Finally, mediation resulted in higher joint outcomes than did no mediation and had a stronger effect in US. (vs. Hong Kong) negotiations.  相似文献

Racemicd,l-lactate has long been used in burn therapy as Ringer’s lactate and in peritoneal dialysis fluid for treatment of renal failure. The d-lactate component of this racemic mixture is known to cause two forms of neurological toxicity in patients: encephalopathy and, in a subset of the population, panic reaction. Here we demonstrate that coma, similar in degree to that produced by blood levels of 75 mM ethanol was induced in rats by the intraperitoneal infusion of sodiumd-lactate sufficient to raise serumd-lactate concentration to 25 mM, whereas infusion of equal quantities of sodiuml-lactate produced no observable neurological effect. We further demonstrate that the intravenous infusion of racemicd,l-lactic acid into 48-hour fasted rats produced serious disturbances of cardiac rate and rhythm leading to death. When serumd-lactate concentration had reached 1–2 mM there was bradycardia, at 2–3 mM prolongation of QT interval, at 6–7 mM AV block with ectopic escape rhythms, and at 11 mM death in ventricular standstill or fibrillation. In contrast, intravenous infusion ofl-lactic acid to blood levels of 25 mM failed to produce any change in cardiac rhythm. On the other hand, the isolated working heart, free of influence from the central nervous system, displayed no change of cardiac rhythm or physiological function when perfused with 25 mM sodiumd,l-lactate.  相似文献

In a recent paper (Fishbein et al., 1992) gay men's attitudes and subjective norms were found to be accurate predictors of their intentions to perform a variety of sexual behaviors. In addition, the relative importance of norms as determinants of intention was found to be greater in Seattle (a city with a well organized gay community) than in Albany (a city in which the gay community is not well organized). The purpose of the present study was to investigate the extent to which the men's attitudes, subjective norms, and intentions were influenced by a number of situational and individual difference variables. Three hundred and fourteen self-identified gay or bisexual men from Seattle (134), Denver (78), and Albany (102) completed a questionnaire specifically designed for this study. As expected, type of partner and type of sexual activity significantly influenced attitudes, perceived norms, and intentions. In addition, these dependent variables were also influenced, in part, by city of residence, age, and perceived risk of HIV infection. The findings provide additional justification for developing different interventions for gay men in different cities, age, and perceived risk groups.  相似文献

Alcohol-related knowledge and attitudes in people with a mild learning disability, who were either living, or being prepared to live, in relatively independent conditions in the community, were assessed through a structured interview format. Compared with non-learning-disabled teenagers, adults and a hospitalized patient sample, alcohol-related knowledge in the people with a learning disability was found to be significantly poorer, alcohol was reported as having particularly negative effects and susceptibility to social pressure to drink alcohol was greater. A ‘sensible drinking’ group, taking a social skills and influences approach to alcohol education, was conducted with a subgroup of the individuals with a learning disability. The group format and methods, including in vivo sessions in a public house, are described. Follow-up evaluations suggested some significant positive changes in knowledge, attitudes and sensible drinking skills. It is concluded that this population, which is increasingly living, or being moved into, independent conditions in the community, is at least as vulnerable to social influences on alcohol use and abuse as are young people. As with young people, the usefulness of making available such alcohol-education programmes as described in this study, is discussed.  相似文献

Two studies examined effects of interventions to reduce noise levels from portable stereo headphones. Study 1 examined the effectiveness of warning signs posted in and nearby public elevators with 567 passengers possessing a portable headphone (total N = 7,811). During a 9-day baseline, the mean percentage of headphones played at an observer-audible level was 85%. During a subsequent 6-day warning sign phase, the mean percentage of audible headphones declined to 59%, which increased to a mean of 76% during a second baseline phase (5 days). Study 2 assessed the impact of a student confederate who lowered his or her observer-audible headphone volume at the polite request of a second student confederate. Of the 4,069 elevator passengers, 433 possessed a portable headset. The mean percentage of observer-audible headphones during a 4-day baseline was 85%. Subsequently, a 5-day modeling intervention reduced audible volumes to a mean of 46%. During a second baseline phase of 4 days, the mean level was 77%, and during reintroduction of the modeling phase (9 days) the mean level was 42%. The modeling intervention was significantly more effective with women (53% compliance) than men (29% compliance).  相似文献

Group therapy with inner city Hispanic acting-out adolescent males is described as an effective psychotherapeutic modality in treating this difficult population. Topics addressed include the development of personality during adolescence, Hispanic family dynamics and gender roles, group therapy as a pseudofamily structure, stages of group development as they pertain to this population, and the group therapist's role and characteristics in the treatment situation.  相似文献
