Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and tact training by evaluating the effects of a discrete‐trial instruction procedure involving (a) echoic prompts, a constant prompt delay, and error correction for primary targets; (b) inclusion of secondary target stimuli in the consequent portion of learning trials; and (c) multiple exemplar training on the acquisition of item tacts of olfactory stimuli, emergence of category tacts of olfactory stimuli, generalization of category tacts, and emergence of category matching, with three children diagnosed with ASD. Results showed that all participants learned the item and category tacts following teaching, participants demonstrated generalization across category tacts, and category matching emerged for all participants. 相似文献

Involvement in organized sport can be highly demanding for young athletes who encounter many difficult situations and stressors. This can be exacerbated among youth athletes who have been recruited into talent-identification youth sport programs. Given that there are a range of negative consequences that can result when talent-identified (TI) youth athletes are unable to cope with the stressors they encounter, additional support is therefore necessary. Parents are uniquely situated to assist in this regard, but they are not always equipped to provide optimal levels of support. Therefore, the aim of this study was to understand the experiences of being a TI youth athlete and present the findings as “lessons” for parents seeking to enhance their involvement in TI youth sport settings. This article reports on qualitative data collected from the 1st year of a 3-year longitudinal study involving TI youth athletes from South Australia. Fifty male athletes (M age = 14.6 years) participated in focus groups to hear their experiences of being a TI youth athlete and understand what difficulties they want their parents to know. From the thematic analysis, 3 major themes were identified from the focus groups with TI youth athletes: (a) difficulties with being talented, (b) negotiating the future, and (c) playing for improvement. From the findings, a number of lessons for parents and youth sport organizations are offered to assist the transmission of knowledge to an applied setting. 相似文献

Bayesian hypothesis testing presents an attractive alternative to p value hypothesis testing. Part I of this series outlined several advantages of Bayesian hypothesis testing, including the ability to quantify evidence and the ability to monitor and update this evidence as data come in, without the need to know the intention with which the data were collected. Despite these and other practical advantages, Bayesian hypothesis tests are still reported relatively rarely. An important impediment to the widespread adoption of Bayesian tests is arguably the lack of user-friendly software for the run-of-the-mill statistical problems that confront psychologists for the analysis of almost every experiment: the t-test, ANOVA, correlation, regression, and contingency tables. In Part II of this series we introduce JASP (http://www.jasp-stats.org), an open-source, cross-platform, user-friendly graphical software package that allows users to carry out Bayesian hypothesis tests for standard statistical problems. JASP is based in part on the Bayesian analyses implemented in Morey and Rouder’s BayesFactor package for R. Armed with JASP, the practical advantages of Bayesian hypothesis testing are only a mouse click away. 相似文献

Identifying ethically allowable options for infants with trisomy 18 has become more challenging as medical standards of practice shift, based on emerging scientific data and changing societal perceptions of disability. Lack of a stable professional standard of practice ought not prevent ethicists from facilitating a consensus; rather, these "unsettled cases" require an individualized, narrative approach that allows the values of the family and the particularities of each case to provide the necessary additional moral grounding. 相似文献

When making choices, people often try to directly compare the features of different options rather than evaluating each option separately. Not every feature has an analogous (or alignable) feature in the other option, however. In this study, both younger and older adults filled in such gaps when remembering, creating features in the other option to contrast with existing features. Thus, participants had a tendency to remember choice options as more comparable than they originally were. High performance on tasks tapping strategic processing was associated with a pattern of mostly feature-based comparisons during choice for older adults but with a pattern of mostly option-based comparisons for younger adults. This pattern suggests that younger and older adults' comparison processes are influenced by different goals. 相似文献

A great deal is known about the effects of positive reinforcement on response acquisition; by contrast, much less research has been conducted on contingencies applied to errors. We examined the effects of response repetition as an error-correction procedure on the sight-word reading performance of 11 adults with developmental disabilities. Study 1 compared single-response (SR) repetition and multiple-response (MR) repetition, and results showed that all 6 participants acquired more sight words with the MR procedure. Study 2 compared MR error correction following every incorrect response (continuous) and following one third of incorrect responses (intermittent), and results showed that all 6 participants acquired more sight words when error correction was continuous. Study 3 compared MR error correction in which errors required practice of the training word (relevant) versus a different word (irrelevant), and results showed that 3 of 9 participants showed better performance under the relevant condition; however, all participants showed improvement even under the irrelevant condition. Findings are discussed in terms of the behavioral processes by which error correction may enhance performance during acquisition. 相似文献

Social Support Mediates the Effects of Dual-Focus Mutual Aid Groups on Abstinence from Substance Use
Laudet AB Cleland CM Magura S Vogel HS Knight EL 《American journal of community psychology》2004,34(3-4):175-185
Background: Specialized 12-step based groups have emerged to address the needs of persons recovering from both substance abuse and psychiatric illness. Objective: This study investigates the role of social support in mediating the association between mutual aid participation and subsequent substance use for dually diagnosed persons. Method: A cohort of Double Trouble in Recovery (DTR) members in New York City were studied prospectively over a two-year period. Findings: Longer DTR participation during the first year of the study was associated with lower substance use in the second year; that effect was partially explained by the maintenance of high level of social support. Conclusion: These findings speak of the enduring influence of 12-step attendance on reducing substance use, and underline the importance of both 12-step attendance and supportive networks for dually diagnosed persons. 相似文献

We evaluated the long-term therapeutic effects of noncontingent reinforcement (NCR). In Experiment 1, NCR effects were examined with 2 participants' arbitrary responses; in Experiment 2, NCR was used as treatment with 3 participants whose self-injurious behavior (SIB) was maintained by automatic reinforcement. In both experiments, NCR consisted of continuous access to a highly preferred leisure item and was implemented initially during 10-min and later during 120-min sessions. Varied reinforcers (leisure items) were subsequently introduced during 120-min sessions to determine if treatment effects might be extended. Finally (Experiment 2 only), NCR was implemented throughout the day in participants' homes. Results of Experiments 1 and 2 showed that reinforcers obtained through object manipulation can compete with those obtained automatically by engaging in SIB during brief NCR sessions. However, data from the 120-min sessions indicated that satiation to a specific leisure item might occur over periods of time more typical of those during which treatment would be implemented. Access to a variety of highly preferred leisure items extended the effectiveness of NCR for some individuals. When NCR was implemented throughout the day (Experiment 2), therapeutic effects were shown to be maintained for up to 1 year. 相似文献
