Information on response requirements compared with information on food density as a reinforcer of observing in pigeons

On a variable-interval schedule, pecking the key to the pigeon's right (observing response) produced red or green displays relating to the delivery of grain and its dependence on pecking the key to the left (food key). During various blocks of sessions, mixed (no stimulus change) schedules including the following pairs of components were temporarily converted by the observing response to their corresponding multiple (correlated stimuli) schedules: variable-interval 60-s, extinction; variable-interval 60-s, variable-time (response-independent) 60-s; extinction, variable-time 60-s. Differences in food delivery maintained substantial rates of responding on the observing key, without regard to pecking requirements on the food key. Although stimuli correlated with differences in the response requirement on the food key maintained higher observing rates than those maintained by uncorrelated stimuli, they were much lower than those based on food. The value of predictive stimuli as reinforcers is determined by the value of the events predicted. In particular, the cost of pecking appears to be low, and this may place limitations on the applicability of energy-based and economic models of behavior. 相似文献

This study examines the prevalence of endorsing the twelve step approach and the use of prayer, meditation, and holistic techniques
in a national sample of 139 substance abuse treatment centers. Ninety one percent of the programs endorsed a twelve step orientation.
Twenty six percent of the programs actively used prayer and 58% used meditation as a component of treatment. Thirty three
percent of the programs used some form of a self-designated holistic technique. There was a divergent range of techniques
that were used by programs, falling into four broad categories: (1) nutrition, exercise, relaxation and physical health; (2)
recreation and adventure-based activities; (3) religious and spiritual practices; and (4) the use of specific therapy modalities. 相似文献

In this qualitative research study, the authors use grounded theory analysis to examine the experiences of clinicians in training and use client feedback to inform treatment. Twenty-six marriage and family therapy graduate students in their first or second semester of clinical practicum participated in this study. Participants were trained in eliciting and responding to client feedback at the end of every therapy session. At the end of the semester, participants reflected on their learning experience. Participant experiences reflected a developmental learning process beginning with significant challenges followed by positive clinical changes and positive clinician changes, culminating in overall buy-in regarding the importance of client feedback for nearly all clinicians. The results support the literature that client feedback directly informs the therapeutic process while suggesting important recommendations for training new clinicians in learning to use client feedback. 相似文献

A durable low-cost data-recording and feedback system is described. Data transcribed with a special pen onto a plastic sheet can be removed only with two solvents. These data can be displayed for feedback purposes without fear of destruction. 相似文献

对生命进化的本质问题作了新的哲学思考,提出进化的本质是物种在生存的驱动下生存效率的优化过程,是原始细胞自主性与环境选择的双向过程。同时提出推动物种进化的动力在于生存资源稀缺性与物种自私性之间的矛盾和多细胞物种效率优化过程中自身的局部利益与整体利益之间的矛盾。 相似文献

Abstract: Many techniques for automated model specification search based on numerical indices have been proposed, but no single decisive method has yet been determined. In the present article, the performance and features of the model specification search method using a genetic algorithm (GA) were verified. A GA is a robust and simple metaheuristic algorithm with great searching power. While there has already been some research applying metaheuristics to the model fitting task, we focus here on the search for a simple structure factor analysis model and propose a customized algorithm for dealing with certain problems specific to that situation. First, implementation of model specification search using a GA with factor reordering for a simple structure factor analysis is proposed. Then, through a simulation study using generated data with a known true structure and through example analysis using real data, the effectiveness and applicability of the proposed method were demonstrated. 相似文献

Metcalf and Dimidjian (this issue) have provided an important review of the current evidence base for mindfulness‐based cognitive therapy (MBCT) and presented a helpful summary of the proposed mechanisms of change. It is necessary to engage in a continuous dialogue regarding the evidence base for change mechanisms, and the article by Metcalf and Dimidjian highlights an important barrier of concern to the field of treatment outcome research. The present commentary aims to expand the discussion regarding the definition, measurement, and evaluation of “mechanisms of change.” Using MBCT as an example, this commentary addresses the ambiguity surrounding the definition and operationalisation of these mechanisms in research on psychological therapies and how the method of measurement may impact the results obtained in clinical trials. It is argued that a potentially fruitful avenue of future research would involve investigation of techniques, important client‐therapeutic processes, and mechanisms in a single study in order to comprehensively evaluate how change occurs. 相似文献

This study examined self-regulation in the form of selective optimization with compensation (SOC) at work as a moderator of the relationships of job control (as a job resource) and feeling recovered and energized in the morning (as a personal energy resource) with self- and coworker-rated work engagement. SOC was hypothesized to offset low levels of job control and low levels of personal energy. Based on a sample of 405 public-service employees in Germany, including a multi-source subsample of 141 employees and their respective coworkers, the results showed that SOC use moderated the relationship between the level of personal energy and self-ratings as well as coworker ratings of work engagement such that SOC mitigated low levels of personal energy. SOC at work did not offset low job control. The results suggest that using SOC is particularly important when employees lack energy. SOC strategies should, therefore, be fostered by managers and organizations. 相似文献
