Three experiments examined the factors that are responsible for producing a high rate of autoshaped keypecking in pigeons when the conditioned stimulus is followed by varying consequences. In the first experiment, a single group received three serial conditioning schedules presented on different keys. The AB+ schedule consisted of trials in which A was followed by B, which, in turn, was followed by food. The CD+C° schedule consisted of reinforced CD pairings plus presentations of C alone. The EF+/0 schedule consisted of a mixture of reinforced and nonreinforced EF pairings. It was found that responding was most rapid during C, slowest during E, and at an intermediate rate during A. In spite of this ordering A was chosen in preference to C, when these stimuli were presented simultaneously. In Experiments 2 and 3 the schedules AB+A° and AB+/0 were presented to separate groups. The rate of responding during A was substantially greater in the former schedule, yet it was found that this stimulus was equally ineffective as a conditioned reinforcer in both groups. We propose that autoshaped keypecking is composed of two types of response, a conditioned response and an orienting response, which are governed by different processes. 相似文献

The current review summarizes the literature on competing stimulus assessments (CSAs). CSAs are pretreatment assessments designed to systematically identify stimuli that reduce problem behavior (PB), ostensibly through reinforcer competition or substitution. We report on the participant characteristics, outcomes, and predictive validity of published CSAs that included (a) no-stimulus control trial(s), (b) test trials during which each stimulus was available singly and noncontingently, and (c) measurement of PB and stimulus engagement or contact. Results showed that CSAs have broad utility across a variety of topographies and functions of PB. In the majority of CSA applications for which extended analyses, or validations, were performed, stimuli shown to reduce PB during the CSA produced similar reductions during extended analysis. This was the case regardless of topography or function of PB, or whether the stimuli were assumed to be “matched” to the stimulation thought to be produced by PB. Implications for future research are discussed. 相似文献

Subjective well‐being and human welfare around the world as reflected in the Gallup World Poll 下载免费PDF全文
We present data on well‐being and quality of life in the world, including material quality of life such as not going hungry, physical health quality of life such as longevity, social quality of life such as social support, environmental health such as clean water, equality in income and life satisfaction, and levels of subjective well‐being (SWB). There are large differences between nations in SWB, and these are predicted not only by economic development, but also by environmental health, equality and freedom in nations. Improving trends in SWB are seen in many countries, but declining SWB is evident in a few. Besides average differences in SWB between nations, there are also large disparities within many countries. We discuss the policy opportunities provided by national accounts of SWB, which are increasingly being adopted by many societies. They provide the opportunity to inform policy deliberations with well‐being information that reflects not only economic development, but also other facets of quality of life as well. National accounts of SWB reflect the quality of life in areas such as health, social relationships and the natural environment, and therefore capture a broader view of societal well‐being than afforded by measures of economic progress alone. 相似文献

Conveying that psychoanalysis offers rich opportunities for the very early treatment of autistic spectrum disorders, this clinical communication unfolds the clinical process of a 19 month‐old ‘shell‐type’ encapsulated mute autistic girl. It details how, in a four‐weekly‐sessions schedule, infant Lila evolved within two years from being emotionally out‐of‐contact to the affective aliveness of oedipal involvement. Following Frances Tustin's emphasis on the analyst's ‘quality of attention’ and Justin Call's advice that in baby–mother interaction the infant is the initiator and the mother is the follower, it is described how the analyst must, amid excruciating non‐response, even‐mindedly sustain her attention in order to meet the child half‐way at those infrequent points where flickers of initiative on her side are adumbrated. This helps attain evanescent ‘moments of contact’ which coalesce later into ‘moments of sharing’, eventually leading to acknowledgment of the analyst's humanness and a receptiveness for to‐and‐fro communication. Thus the ‘primal dialogue’ (Spitz) is reawakened and, by experiencing herself in the mirror of the analyst, the child's sense of I‐ness is reinstated. As evinced by the literature, the mainstream stance rests on systematic early interpretation of the transference, which has in our view strongly deterred progress in the psychoanalytic treatment of autistic spectrum disorders. 相似文献
