Four experiments assessed the role of response-reinforcement (R-S1) expectancy as rats either learned a discrimination or a discrimination reversal. Experiment 1 showed that the higher the percentage of reinforcement during nondiscriminative pretraining the more quickly a subsequent discrimination is learned. Experiment 2 demonstrated that the overlearning reversal effect (ORE) can be obtained even though the overtraining phase consists of responses to a single neutral card. In Experiment 3 subjects were again overtrained on a single neutral stimulus under conditions of varying reinforcement. ORE was apparent under reinforcement of a high percentage of responses but was not apparent under reinforcement of a low percentage. Experiment 4 revealed that the fewer errors a subject makes prior to reversal the better its reversal performance is. Results of these studies were discussed in terms of generalized attention theories and the expectancy notions of Bolles (Psychological Review, 1972, 79(5), 394–409. 相似文献

The current study extends the literature on the assessment and treatment of rumination through the evaluation of a combined reinforcement‐ and punishment‐based intervention. The study included a single participant with a history of rumination maintained by automatic reinforcement, as identified via a functional analysis. Both noncontingent reinforcement (NCR) with preferred edible items and punishment, in the form of a facial screen, were implemented separately to evaluate their independent effects on the occurrence of rumination. The final treatment package included both NCR and punishment procedures. Implementation of the combined treatment resulted in a 96.5% reduction in rumination relative to baseline. Procedural modifications and integrity errors also were evaluated. 相似文献

Despite considerable interest in understanding how stress influences memory accuracy and errors, particularly in children, methodological limitations have made it difficult to examine the effects of stress independent of the effects of the emotional valence of to-be-remembered information in developmental populations. In this study, we manipulated stress levels in 7–8- and 12–14-year-olds and then exposed them to negative, neutral, and positive word lists. Shortly afterward, we tested their recognition memory for the words and false memory for non-presented but related words. Adolescents in the high-stress condition were more accurate than those in the low-stress condition, while children's accuracy did not differ across stress conditions. Also, among adolescents, accuracy and errors were higher for the negative than positive words, while in children, word valence was unrelated to accuracy. Finally, increases in children's and adolescents’ cortisol responses, especially in the high-stress condition, were related to greater accuracy but not false memories and only for positive emotional words. Findings suggest that stress at encoding, as well as the emotional content of to-be-remembered information, may influence memory in different ways across development, highlighting the need for greater complexity in existing models of true and false memory formation. 相似文献

We investigated individual- and couple-level associations between daily intimacy and affective states (N = 2211 observations) in 20 heterosexual emerging adult couples (age 18–25 years, M = 23) who had been in a sexual relationship with one another for at least 3 weeks (M = 12 months). Individual analyses revealed that emerging adults’ feelings of intimacy varied from day to day and that there were no gender differences in daily intimacy. Affect and intimacy were positively associated within day for women, but not for men. Time-lagged individual-level analyses revealed that prior-day positive or negative affect did not predict present-day intimacy for men or women. However, prior-day intimacy positively predicted present-day positive affect in men and negatively predicted present-day negative affect in women. Time-lagged couple-level analyses revealed that men’s prior-day positive affect positively predicted their female partner’s present-day intimacy. Women’s prior-day intimacy negatively predicted their male partner’s present-day negative affect. Implications of the day-to-day associations of intimacy with positive and negative affect within emerging adult couples are discussed. 相似文献

As monarch of the lordship and (since 1541) kingdom of Ireland, King Henry VIII and his successors imposed the same ecclesiastical and religious policies they devised for England on Dublin, the most English city in Tudor Ireland. Far-reaching changes were effected to quite a remarkable degree. Yet the English Reformation failed to take root in the Irish city. This paper explores both the course of the Reformation in the capital of English Ireland and the reasons for its general failure. It also highlights some implications of Dublin’s experience relevant to continuing debates in English Reformation studies. 相似文献
