Providing independent recreational activities to reduce stereotypic vocalizations in chronic schizophrenics.

We evaluated the effects of minimally supervised, independent recreational activities on stereotypic vocal behavior in two chronic schizophrenic patients. In baseline sessions, subjects were observed during unstructured free time in the psychiatric ward. In treatment sessions, therapists presented preferred recreational materials (magazines, models, and art projects), verbally prompted on-task behavior every 20 min, and, in one condition, administered contingent tokens. Independent recreational activities reduced medium-rate self-talk in one subject and high-rate mumbling in a second subject by 60%-70%. Results were the same with or without contingent tokens. Apparent self-maintaining characteristics of these vocal responses are discussed.     

TRAINING APARTMENT UPKEEP SKILLS TO REHABILITATION CLIENTS: A COMPARISON OF TASK ANALYTIC STRATEGIES

The research was designed to validate procedures to teach apartment upkeep skills to severely handicapped clients with various categorical disabilities. Methodological features of this research included performance comparisons between general and specific task analyses, effect of an impasse correction baseline procedure, social validation of training goals, natural environment assessments and contingencies, as well as long-term follow-up. Subjects were taught to perform upkeep responses on their air conditioner-heating unit, electric range, refrigerator, and electrical appliances within the context of a multiple-probe across subjects experimental design. The results showed acquisition, long-term maintenance, and generalization of the upkeep skills to a nontraining apartment. General task analyses were recommended for assessment and specific task analyses for training. The impasse correction procedure generally did not produce acquisition.     

Training self-advocacy skills to adults with mild handicaps.

We developed and empirically evaluated an instructional program to teach self-advocacy skills to eight young adults with mild handicaps. Participants were taught to discriminate whether or not possible violations of legal rights occurred in socially validated scenarios and, if so, to role-play how to redress rights violations. Experimental control was demonstrated with a multiple probe design across four general legal rights categories for the discrimination component of training, and a multiple probe across groups of subjects for the redressing legal rights component of training. Participants'' behavior was probed in simulations and deceptions of legal rights violations in natural settings. There were marked increases in dependent measures after instruction. Difficulties in assessing generalization and maintenance of low-rate behaviors and suggestions for future research are presented.     

On testing the equality of proportions in the paired case with incomplete data

The problem of testing two correlated proportions with incomplete data is considered by means of Monte Carlo simulations studies. A test proposed in this paper, which can be regarded as a generalization of McNemar's test, is recommended in all cases with incomplete data and not too small samples.     

信息加工阶段独立资源的新证据

本研究对与加工阶段有关的独立资源问题进行了研究。实验采用双任务测定方法 ,分别设计了模拟追踪、记忆搜寻和模拟监控等三种主作业 ,以及简单反应时、复杂反应时和手指节奏敲击等三种次作业。这些作业分别动用了与三维度资源理论加工阶段维度的视觉编码、中枢加工和运动输出相对应的三类独立资源。将这六种作业进行匹配 ,共组合成 3× 3种双任务作业情境。实验以次作业绩效为分析指标。结果发现 ,以往对信息加工独立资源的分类过于粗略。另外 ,研究还发现 ,除独立资源外 ,还存在某些通用资源。     

Precedent Autonomy and Subsequent Consent

Honoring a living will typically involves treating an incompetent patient in accord with preferences she once had, but whose objects she can no longer understand. How do we respect her “precedent autonomy” by giving her what she used to want? There is a similar problem with “subsequent consent”: How can we justify interfering with someone's autonomy on the grounds that she will later consent to the interference, if she refuses now? Both problems arise on the assumption that, to respect someone's autonomy, any preferences we respect must be among that person's current preferences. I argue that this is not always true. Just as we can celebrate an event long after it happens, so can we respect someone's wishes long before or after she has that wish. In the contexts of precedent autonomy and subsequent consent, the wishes are often preferences about which of two other, conflicting preferences to satisfy. When someone has two conflicting preferences, and a third preference on how to resolve that conflict, to respect his autonomy we must respect that third preference. People with declining competence may have a resolution preference earlier, favoring the earlier conflicting preference (precedent autonomy), whereas those with rising competence may have it later, favoring the later conflicting preference (subsequent consent). To respect autonomy in such cases we must respect not a current, but a former or later preference.     

Resurgence of time allocation

The resurgence of time allocation with pigeons was studied in three experiments. In Phase 1 of each experiment, response‐independent food occurred with different probabilities in the presence of two different keylights. Each peck on the key changed its color and the food probability in effect. In Phase 2, the food probabilities associated with each keylight were reversed and, in Phase 3, food was discontinued in the presence of either keylight. The food probabilities were .25 and .75, in Experiment 1, and 0.0 and 1.0 in Experiment 2. More time was allocated to the keylight correlated with more probable food in Phases 1 and 2, and in Phase 3 resurgence of time allocation occurred for two of three pigeons in Experiment 1, and for each of four pigeons in Experiment 2. Because time had to be allocated to either of the two alternatives in Experiments 1 and 2, however, it was difficult to characterize the time allocation patterns in Phase 3 as resurgence when changeover responding approached zero. In Experiment 3 this issue was addressed by providing a third alternative uncorrelated with food such that in each phase, after 30 s in the presence of either keylight correlated with food, the third alternative always was reinstated, requiring a response to access either of the two keylights correlated with food. In this experiment, the food probabilities were similar to those in Experiment 1. Resurgence of time allocation occurred for each of three pigeons under this procedure. The results of these experiments suggest that patterns of time allocation resurge similarly to discrete responses and to spatial and temporal patterns of responding.     

心理时间旅行的动力机制：自我的作用

选取120名大学生,通过两个研究考察了自我在心理时间旅行中的动力机制。研究1以核心自我评价为评估自我概念的指标,发现自尊和一般自我效能对指向未来的心理时间旅行具有一定的预测效力。研究2通过启动使不同类型的自我概念在意识中占优,发现互倚组比独立组报告出更多具体的事件,且更关注他人和关系。研究表明,自我概念能够引导个体对过去和未来事件的建构。     

Creativity and the artwork: the perspectives of a painter and a philosopher

Creativity in Robert Henri's view is a gratuitous act, shot through with mystery; what is left after such an act is the artwork itself as concrete evidence that such a heightened state of consciousness has been achieved. This paper will examine Henri's understanding of the nature of creativity from his perspective as a twentieth century New York painter, in conjunction with Eliot Deutsch's theoretical insights as a philosopher deeply interested in the nature of the experience of an artwork. In his Essays on the nature of art, Deutsch presents the view that the experience of an artwork involves the assimilation of the work's aesthetic force, the recognition of its meaning, the discernment of its formal dimensions, and ‘calls for a special appropriation that yields an integrated wholeness’. This paper presents commonalities between Henri's and Deutsch individual perspectives and discusses some value‐centred educational implications that could be drawn from these commonalities.     

After the Terror: A Book and Further Thoughts

There are great goods desired by all of us, and the lack of themmakes for bad lives. One sample of bad African lives involves aloss of 20 million years of living time. The questions raised bythese and other facts are to be answered by the Principle ofHumanity, about bad lives and rationality. It is superior tomorality of relationship and all else, and in a way is undeniable.The principle together with other things issues in six propositions.One gives us a moral responsibility, our politicians at our head,for the terrorism of September 11. To be ordinary is not to beinnocent. Another proposition is that the Palestinians have a moralright to their terrorism. The latter proposition can be given stillmore support than in the book from which this paper derives.
