This study investigated the effectiveness of response cost and differential reinforcement of other behavior (DRO) in reducing the disruptive behaviors of 25 children in a preschool classroom. Using an alternating treatments design, disruptive behavior was reduced when the participants earned tokens for the absence of disruptive behavior (DRO) or lost tokens for the occurrence of disruptive behavior (response cost). Initially, DRO was more successful in reducing the number of disruptive behaviors; however, over time, response cost proved to be more effective. 相似文献

This article presents and discusses four clinical cases that exemplify the complexity of ethical dilemmas concerning the provider's obligation to disclose or withhold genetic information from patients. Case 1: What is the responsibility of the cancer genetics provider to ensure that a positive test results is shared with distant relatives? Case 2: To ensure that results go to at-risk relatives, do we have the right to ignore the wishes of the designated next-of-kin? Case 3: Do we have the right to reveal a familial BRCA1 mutation to a patient's relative, who is at 50% risk? Case 4: Do we have an obligation to reveal that a patient is not a blood relative and therefore, not at risk to have inherited a familial mutation? These cases form the basis for discussing the provider's dual obligations to keeping patient confidentiality and informing patients and families about risk (i.e. duty to warn). We also provide a summary of consensus points and additional discussion questions for each case. 相似文献

Checking behavior is among the most common forms of compulsions in OCD. Recent research suggests that repeated checking decreases memory confidence, and supports theoretical models of how repeated checking is maintained. The current paper presents findings from two studies exploring the boundaries of memory distrust from repeated checking. Results of study 1 show that repeated checking of a real stove decreases memory confidence, vividness, and detail (i.e., metamemory), and leads to a greater reliance on knowing as a source of memory, without meaningfully altering memory accuracy. Results of study 2 suggest that these changes in metamemory are observed after performing a relatively low number of checks on one occasion. The findings are considered within the context of theoretical models of checking and future directions are delineated. 相似文献

This study investigated theoretically predicted links between attachment style and a physiological indicator of stress, salivary cortisol levels, in 124 heterosexual dating couples. Cortisol was assessed at 7 points before and after an experimental conflict negotiation task, creating a trajectory of stress reactivity and recovery for each participant. Growth modeling of cortisol data tested hypotheses that (a) insecurely attached individuals show patterns of greater physiological stress reactions to interpersonal conflict than do securely attached individuals and (b) people with insecurely attached partners show patterns of greater stress in reaction to relationship conflict than those with securely attached partners. Hypothesis 1 was supported, but men and women differed in the type of insecure attachment that predicted stress trajectories. Hypothesis 2 was supported for men, but not for women. The discussion emphasizes the role of gender role norms and partner characteristics in understanding connections between adult attachment and patterns of cortisol responses to interpersonal stress. 相似文献

Data are presented on social and vocal learning in cowbirds (Molothrus ater) housed in large aviaries and given more degrees of freedom than in conventional experimental studies. The studies show that social and vocal outcomes are facultative responses to social contexts. Several findings are reviewed: First, cowbirds quickly self-organize into groups by age and sex; second, opportunities to interact across age and sex do exist and affect courtship competence; third, female cowbirds organize themselves differently in the presence and absence of male competition; and fourth, young, naive cowbirds show rapid and differential sensitivity to group dynamics. Taken as a whole, the data show that social Umwelten are dynamic, developmental ecologies. 相似文献

Alibi believability can be affected by characteristics of the alibi corroborator, including the relationship between the defendant and corroborator, which has been studied extensively by researchers. The corroborator's certainty that they were together at the time of the crime may also influence alibi believability, but only a few studies have examined this. Another factor that may affect believability is the corroborator's cooperativeness with the police, which is yet to be studied in the alibi context. Online U.S. participants recruited from CloudResearch (N = 280) acted as mock jurors and evaluated a mock arson case where the defendant used an alibi defence. The alibi corroborator's relationship to the defendant (brother/neighbour), the certainty that they were together at the time (65%/100%) and cooperativeness with police (cooperative/uncooperative) were manipulated between participants. The participants were evenly split when it came to verdict (p > .05) but were more likely to vote guilty when the corroborator was a brother rather than a neighbour (p < .01) and when the brother was uncooperative versus cooperative (p < .05). As expected, alibis were more believable when they were corroborated by a neighbour rather than a brother and when the corroborator was 100% certain that they were together versus 65% certain (ps < .01). Alibis were also more believable when the corroborator cooperated than when he was uncooperative (p < .01). Cooperative (vs. uncooperative) corroborators led to more positive defendant and corroborator views on all six character trait measures (ps < .01). Implications and future directions are discussed. 相似文献

The acquisition and expression of political orientations are highly age-related; however, the nature of age-typical forms is rarely conceptualized in socialization research. The first part of this article examines the hypothesized nature of "age invariance" identified by criminologists in the study of deviant behavior and the inverted U-curve of voting behavior identified by political scientists. The second part uses survey data from German youth and young adults ( n = 7,280, ages 13 to 30) to describe typical age patterns for various types of unconventional behavior. The more unconventional the behavior, the more the curve resembles what criminologists have long found for deviant behavior. Youth approval of the more disruptive forms of political behavior has a left-skewed age distribution that is also typical of deviant behavior. This suggests an unappealing combination of potential actionism and political ignorance occurring in late adolescence, a possibility that ought to be of consequence for the design of civic education and other interventions. From a research perspective, these age-typical patterns can be useful as a theory-building and theory-testing strategy by treating them as baselines against which individual and cultural variations can be measured. 相似文献

Latent curve analysis 总被引:16,自引:0,他引:16
As a method for representing development, latent trait theory is presented in terms of a statistical model containing individual parameters and a structure on both the first and second moments of the random variables reflecting growth. Maximum likelihood parameter estimates and associated asymptotic tests follow directly. These procedures may be viewed as an alternative to standard repeated measures ANOVA and to first-order auto-regressive methods. As formulated, the model encompasses cohort sequential designs and allow for period or practice effects. A numerical illustration using data initially collected by Nesselroade and Baltes is presented.The authors wish to thank John Nesselroade for providing us the data for our illustration and Karen Paul and Connie Tilse for assisting in the data analysis. This research was supported by a grant (No. AG03164) from the National Institute on Aging to the senior author. 相似文献

Change in adult intellectual performance was assessed with longitudinal data from the Intergenerational Studies at the Institute of Human Development. Wechsler Intelligence data from two age cohorts spanning ages 18 to 61 were analyzed at the subtest and item level. Hotelling T2 analyses on sets of equivalent items from Wechsler subtests were studied to determine if change in response occurred between pairwise combinations of occasions of test administrations. We used Bowker's test to analyze data at the item level to determine the direction of change in performance. Consistent improvement in performance occurred between the ages of 18-40 and 18-54. Between the ages of 40 and 61, results showed mostly improved performance on the Information, Comprehension, and Vocabulary subtests, mixed change on the Picture Completion subtest, and decline on the Digit Symbol and Block Design subtests. The pattern of mixed change on the Picture Completion subtest indicated improvement on the easy items and decline on the difficult items. Decline in performance on the Block Design test occurred only for the most difficult items. 相似文献
