A pictorial preference assessment was conducted for 2 individuals with autism who had programmed breaks in their behavior plans. Assessed break environments were individualized, based on indirect assessments and direct observations. The most highly (HP) and least preferred (LP) environments and a control with no associated break were included in a subsequent reinforcer assessment using a concurrent‐chains arrangement within a reversal design. Participants selected a multitask sequence (initial link) associated with one of the break environments. Phase A evaluated the reinforcing properties of all three breaks; the HP was removed in Phase B. Both participants allocated more responding to HP than LP, and to LP than control, suggesting that breaks functioned as reinforcers. The results indicated that preference assessment technology can be used to identify highly preferred breaks that function as reinforcers. Social validity measures indicated that the individuals' clinicians found the results useful for future clinical programming. 相似文献

In this study, four children with autism were assessed to determine their preference choices for toothbrushes and toothpastes included during self-care skills teaching sessions. For two of the children, the presence of high-preference (HP) materials was associated with improved independent tooth brushing when compared to the presence of low-preference (LP) materials. There was no difference in independent tooth brushing between HP/LP conditions for the other two children. These findings suggest that preference and choice of materials alone can be a helpful instructional strategy for care providers serving children who have neurodevelopmental disorders and skill deficits. 相似文献

We replicated the response‐restriction (RR) preference assessment and compared results in terms of preference hierarchies to those from free‐operant and multiple stimulus without replacement (MSWO) formats with six children with autism spectrum disorders (ASDs). We also assessed social validity of each format with teachers and clinicians who work with children with ASDs. Complete hierarchies were produced in four of 18 assessments and with MSWO and RR formats only. Results of the social validity assessment varied across raters, with each preference assessment format receiving the highest rating from at least one rater. Results are discussed in terms of practical recommendations and relative to the preference assessment literature as a whole. 相似文献

The aim of this study was to profile the psychological coping, learning potential and career-related interests of 251 candidates for operational force military selection for the South African National Defence Force (SANDF) – 26 of whom were successful in the selection. Data on their sense of meaning, learning potential and career-related interest were gathered using standardised measures supplemented with open-ended responses. The data were analysed to compare the profiles of the successful candidates against those not selected. The selected group showed significantly higher mean scores on meaningfulness and learning potential, and lower scores for career-related interest in law and medicine. Findings suggest that psychological coping, learning potential and career-related preference information can be used to refine the selection of operational force military candidates. 相似文献

We propose quantitative experimental approaches to the question of whether positive and negative reinforcement are functionally different, and discuss scientific and ethical concerns that would arise if these approaches were pursued. 相似文献

Aim of this study was to investigate the preferential looking behaviour, subsequent to a familiarization task (8-min) with a previously responsive or motionless face, before and after a sleep cycle. Moreover, the role of the active sleep in memory consolidation of the responsive or motionless faces was explored. Hypotheses were that the newborns undergoing a motionless familiarization will exhibit a novelty effect (preference for the novel face) whereas the newborns undergoing a responsive familiarization will show a familiarity effect (preference for the known face) before and after the sleep cycle; moreover, the amount of active sleep will be associated with the looking time at the known face after a sleep cycle.Forty-five healthy full-term newborns were randomly assigned to two groups (group 1: motionless-familiarization and group 2: responsive-familiarization); in both groups newborns were video-recorded during four post-familiarization face-preference tasks, two of them performed before and two after a sleep cycle.During the pre-sleep-trials, there was not a significant preference for one face in both groups. During the post-sleep trials, the newborns showed a clear preference for the novel face. This effect was more evident in group 1. Only in group 2 there was a significant positive correlation between the active sleep duration and the looking duration at the known-face during the post-sleep trials (r = 0.41; p = 0.040). Multiple regression confirmed that only in the group 2 the total duration of the active sleep was associated with the looking duration at the known-face during the post-sleep trials (Adjusted R2 = 0.13; β = 0.41; t = 2.2; p = 0.040).Findings showed that in newborns the face representation can be recalled after a sleep cycle. Moreover, the amount of the active sleep predicted the post-sleep looking toward the known-face only in the newborns who interactively familiarized with the face. 相似文献

As the cultural dynamic continues to become increasingly complex, it is critical to assess cultural factors that influence practice. The present study considers the treatment preferences of Japanese mothers of children with developmental disabilities. After answering demographic questions, each participant was given four scenarios and asked how they would respond by choosing one of four interventions (differential reinforcement, ignoring, reprimanding, and time-out). Overall, we found that parents preferred differential reinforcement strategies the most. Moreover, parents who reported that their children had a history of involvement with applied behavior analysis were especially likely to choose differential reinforcement. Implications for future research and practice are provided. 相似文献

How do people stretch their understanding of magnitude from the experiential range to the very large quantities and ranges important in science, geopolitics, and mathematics? This paper empirically evaluates how and whether people make use of numerical categories when estimating relative magnitudes of numbers across many orders of magnitude. We hypothesize that people use scale words—thousand, million, billion—to carve the large number line into categories, stretching linear responses across items within each category. If so, discontinuities in position and response time are expected near the boundaries between categories. In contrast to previous work (Landy, Silbert, & Goldin, 2013) that suggested only that a minority of college undergraduates employed categorical boundaries, we find that discontinuities near category boundaries occur in most or all participants, but that accurate and inaccurate participants respond in opposite ways to category boundaries. Accurate participants highlight contrasts within a category, whereas inaccurate participants adjust their responses toward category centers. 相似文献

心理不安全感是指人们对可能遭受的伤害与威胁的担忧与焦虑。当下, 许多个体都是在心理不安全的状态下进行决策。对于心理不安全状态下的风险偏好规律, 现有研究得到了矛盾的结果。此外, 心理安全感对风险偏好的作用机制尚不明确。本研究聚焦心理安全感对风险偏好的影响, 考察心理安全感的补偿机制在其中的中介作用, 并探讨选项分布情况在其中的调节作用, 以此揭示心理安全感为何及如何作用于风险偏好。研究结果将有助于明确决策者在心理不安全状态下的风险偏好规律, 从而完善现有的风险决策理论。同时, 为公共管理政策制定提供科学依据。 相似文献
