Evaluating the effects of discriminability on behavioral persistence during and following time‐based reinforcement

With four children with autism we evaluated a refinement to time‐based reinforcement designed to reduce response persistence when we simultaneously introduced time‐based reinforcement and extinction. We further evaluated whether this refinement mitigated response recurrence when all reinforcer deliveries ceased during an extinction‐only disruptor phase. The refinement involved increasing the saliency of the contingency change from contingent reinforcement (during baseline) to time‐based reinforcement by delivering different colored reinforcers during time‐based reinforcement. Behavioral momentum theory predicts that increasing the discriminability of the change from variable‐interval to variable‐time reinforcement should lead to faster reductions in responding. We present data on four participants, three of whom displayed response patterns consistent with the predictions of behavioral momentum theory during time‐based reinforcement. However, the participants showed more varied patterns of recurrent behavior during extinction. We discuss these results within a translational research framework focusing on strategies used to mitigate treatment relapse for severe destructive behavior, as time‐based reinforcement is one of the most commonly prescribed interventions for destructive behavior displayed by individuals with intellectual and developmental disabilities. 相似文献

Oncologic patients are exposed to a higher risk of suicidal behaviors than the general population. In this study, we aim to examine the severity of suicidal ideation in a sample of oncologic patients considering different psychological and clinical features. We interviewed 202 inpatients receiving curative or palliative treatment in a medical oncology ward of a Spanish hospital during the period 2012–2014. A complete assessment of psychosocial factors, cancer diagnoses (lung, colon rectum, and genitourinary system), and suicidal behaviors were made during admission, including validated questionnaires about depression, anxiety, personality, quality of life, body image, life threatening events, hopelessness, and suicidal ideation. The characteristics of inpatients with high and low suicidal ideation were retrospectively compared. A logistic regression model was constructed to examine the relationship between the significant factors retained after the univariate analyses. One of every four patients (n = 51; 25.24%) presented high scores of suicidal ideation. Logistic regression analyses retained depression (OR = 3.55; 95% CI = 1.25–11.68; p = .016), hopelessness (OR = 8.78; 95% CI = 3.44–25.88; p ≤ .001), personality (OR = .44; 95% CI = .2–.96; p = .038), and advanced age (OR = 2.60; 95% CI = 1.18–5.98; p = .016) as the main risk factors for high suicidal ideation. Suicidal ideation was frequent among oncologic patients. These patients should receive closer monitoring, especially, when old, retired, or severely depressed. 相似文献

A road sign with the text «Share the road» and a picture of a smiling cyclist and a passing car was evaluated in a before–after study with surveys among cyclists and car drivers. The sign was set up at two sites on a test road near Oslo in summer 2014. A similar road was used as a comparison. About two thirds of the participants on the test road had noticed the sign. The majority liked it and agreed with its message. Cyclists have more often noticed the sign than car drivers have and they were somewhat more positive towards the sign. Effects on self-reported behavior and the perceived behavior of others were evaluated by comparing changes from the before- to the after-period between test and comparison road. Self-reported behavior of both cyclists and car drivers has improved on the test road after the sign was set up, especially in overtaking situations, and these results are in accordance with how cyclists and car drivers perceived each other’s behavior. The general perception of other road users has improved as well. The results are most likely representative of similar roads with a large proportion of car traffic that is related to recreation and a relatively low level of conflict. 相似文献

Like other Western countries, Spain is rapidly becoming more secularized. While there is almost unanimous agreement that this is happening, significant discord exists about the phases of the process and the speed of its development. This is mostly due to the use of partial and sometimes unreliable data. The aim of this study is to remedy these uncertainties. Our work is based on the data provided by time‐use surveys conducted in 2003 and 2010. Using some basic provisional but reasonable assumptions, we demonstrate that it is possible to identify a plausible dynamic of secularization in Spain starting in the second half of the 19th century. We also highlight the fact that the different indicators feature some significant time lags. Indeed, the dating of the start of the secularization process varies depending on whether reference is made to data on birth cohorts, the overall population, or the “visibility” of the phenomenon. 相似文献

中国国民心理健康素养的现状与特点 总被引:2,自引:0,他引:2
本研究以系统的全国抽样调查方式, 了解我国国民心理健康素养现状。结果显示, 我国成年公众的心理健康素养总体处于中偏低水平; 其发展水平在地域、人口学分布上比较均衡; 在结构上, 公众心理健康素养的发展表现出心理健康维护和促进的素养高于心理疾病应对的素养, 自助的素养高于助人的素养两个特点。调查还发现, 个体心理健康素养中, 知识观念部分个体差异较大, 态度和习惯部分个体差异较小; 在心理健康素养的社会性影响因素方面, 社会经济地位是所考察变量中效应最大的因素, 且其对素养的知识观念方面影响较大, 对素养的态度习惯方面影响较小。调查结果提示, 要充分认识心理健康素养提升任务的艰巨性; 在实践策略上, 宜以提升心理疾病应对的素养作为当前的工作重点和突破口。 相似文献
