This randomized controlled trial tested the effects of a theory-based culture-sensitive HIV risk-reduction intervention among
496 inner-city African American adolescents (mean age = 13 years) and examined the generality of its effects as a function
of the facilitator's race and gender and the gender composition of the intervention group. Adolescents who received the HIV
risk-reduction intervention expressed more favorable behavioral beliefs about condoms, greater self-efficacy, and stronger
condom-use intentions postintervention than did those who received a control intervention on other health issues. Six-month
follow-up data collected on 93% of the adolescents revealed that those who received the HIV risk-reduction intervention reported
less HIV risk-associated sexual behavior, including unprotected coitus, than did their counterparts in the control condition.
Self-reported sexual behavior and changes in self-reported behavior were unrelated to scores on a standard measure of social
desirability response bias. There was strong evidence for the generality of intervention effects. Moderator analyses testing
eight specific interaction hypotheses and correlational analyses indicated that the effects of the HIV risk-reduction intervention
did not vary as a function of the facilitator's race or gender, participant's gender, or the gender composition of the intervention
group.

This study attempted to test the hypothesis that the temporal structure of spontaneous speech is modifiable by reinforcing and punishing pauses, of a certain duration, in an operant conditioning situation. Pause rate was significantly affected by these contingencies: moreover, rate of change was rapid, indicating a prepared association between pausing and such contingencies. This study also attempted to test the hypothesis that there is a class of noncognitive pauses in monologue by punishing UPs to determine if UPs can be eliminated without affecting speech content. Although this manipulation did lead to a decline in pause rate, a significant increase in the amount of filled hesitation, particularly in repetition, resulted. This suggests that the overall amount of hesitation is fixed by the cognitive demands of the task but that a speaker is able to adapt to different interactional contexts by varying the category of hesitation used for cognitive planning. 相似文献

Why do people resist evidence that challenges the validity of long–held beliefs? And why do they persist in maladaptive behavior even when persuasive information or personal experience recommends change? We argue that such defensive tendencies are driven, in large part, by a fundamental motivation to protect the perceived worth and integrity of the self. Studies of social–political debate, health–risk assessment, and responses to team victory or defeat have shown that people respond to information in a less defensive and more open–minded manner when their self–worth is buttressed by an affirmation of an alternative source of identity. Self–affirmed individuals are more likely to accept information that they would otherwise view as threatening, and subsequently to change their beliefs and even their behavior in a desirable fashion. Defensive biases have an adaptive function for maintaining self–worth, but maladaptive consequences for promoting change and reducing social conflict. 相似文献

Right-handed participants made ballistic force impulses with the index finger of their left or right hand to match the amplitude of 2 successive visual targets whose onset was separated by 600-850 ms. The targets specified either low- (10% of maximum voluntary contraction; MVC) or high- (25% MVC) force level and were presented in all combinations (low-low, low-high, high-low, high-high). The amplitude of the 1st force impulse affected that of the 2nd, forming an effect that was greatest at the shortest interresponse intervals and that decayed with increasing intervals. This effect was smaller with a shorter time course in the dominant hand than the nondominant hand, suggesting a greater ability of the dominant hand to make successive independent responses. 相似文献

Traditional self-report ratings have some measurement problems that a relatively new method, best-worst scaling (BWS; Finn & Louviere, 1992), may overcome. This alternative method, based on Louviere's BWS, can be used to measure the relative importance or perceived trade-offs among choice alternatives. The method is illustrated as an alternative to the Schwartz Value Survey (SVS; Schwartz, 1992). In a series of samples, it was found that Schwartz values best-worst survey (SVBWS) reproduced Schwartz's (1992) theoretical value structure and supported hypothesized relationships between values and value-expressive behaviors, ethnocentrism, and environmental-related tourism activities. In addition, the SVBWS approach took significantly less respondent time than the traditional SVS approach. 相似文献

The current research challenges the widespread truism that recalling a positive self necessarily increases self-esteem, whereas recalling a negative self necessarily decreases self-esteem. Four experiments demonstrate that chronically happy people show a relative increase in self-esteem by recalling either a positive or a negative self. Chronically sad people, however, show a relative decrease in self-esteem by recalling either a positive or a negative self. These effects are due to divergent perceptions of mood congruence between the recalled self and the current self. Specifically, happy people perceive high mood congruence between a recalled positive self and the current self but low mood congruence between a recalled negative self and the current self. In contrast, sad people perceive high mood congruence between a recalled negative self and the current self but low mood congruence between a recalled positive self and the current self. Independent of chronic mood, mood congruence leads to perceptions of temporal recency, whereas mood incongruence leads to perceptions of temporal distance. In line with the inclusion-exclusion model of social judgment, perceived temporal recency elicits assimilation effects on self-esteem, whereas perceived temporal distance elicits contrast effects on self-esteem. 相似文献
