成年人现实生活问题解决的年龄差异

采用自行编制的十个与现实生活有关的问题,对２０至８５岁的成年人,分成青年至老老年四个年龄组进行测验,试图探讨成年人现实生活问题解决的年龄差异;并同时进行２０个问题（简称猜图）作业的实验,以期对比研究。结果看到：（１）两组主试对现实生活问题解决的评分一致率合格（ｒ值均在０．７４以上）。（２）对现实生活问题解决提出方案的数量（Ｎ）,三个较年轻组比老老年组答案多些;解决问题有效最高分（Ｈ）和各方案的平均     

PROBLEM BEHAVIOR DURING PREFERENCE ASSESSMENTS: AN EMPIRICAL ANALYSIS AND PRACTICAL RECOMMENDATIONS

Preferences of 2 children with developmental disabilities, whose functional analyses indicated that their problem behavior was maintained by access to tangible items, were assessed using three formats (i.e., paired stimulus [PS], multiple‐stimulus without replacement [MSWO], and free operant [FO]). The experimenter administered each format five times and compared levels of problem behavior across formats in a multielement design. Both participants exhibited problem behavior in PS and MSWO formats but not in the FO format. Results are discussed in terms of recommendations for practitioners.     

NEO-POSITIVISM ABOUT RIGHTS THE PROBLEM WITH 'RIGHTS AS ENFORCEABLE CLAIMS'

ABSTRACT Sue James recommends an 'enforcement account' of rights, where a right is to be understood simply as an enforceable claim. I show that adopting this analysis of rights implies giving up non-rhetorical, important, uses of the word 'right' which are possible on the best alternative theory of rights to James's position: the ability to deny a moral right's existence, even where claims are effectively enforced; the notion of a right's violation; and the idea that rights imply entitlement to make a demand, and not just enforcement of demands. Thus, adopting James's position implies giving up much more than mere rhetoric about rights.     

NONCONTINGENT REINFORCEMENT AS TREATMENT FOR SEVERE PROBLEM BEHAVIOR: SOME PROCEDURAL VARIATIONS

Noncontingent reinforcement (NCR) as a treatment for problem behavior has typically included (a) continuous access to reinforcers at the onset of treatment and (b) extinction. We extended research on NCR by conducting a three-phase preliminary investigation of these components. In Phase 1, a functional analysis showed that the problem behavior of 3 participants with developmental disabilities was maintained by tangible positive reinforcement. In Phase 2, treatment started with the initial NCR interval based on the latency to the first problem behavior during baseline. In Phase 3, treatment consisted of NCR without extinction to determine whether extinction was an essential treatment component. Results showed that the initial NCR schedule based on latency (Phase 2) and NCR without extinction (Phase 3) were effective for reducing rates of problem behavior compared with baseline. Findings are discussed regarding the initial schedule of reinforcement and extinction as components of NCR.     

A HARD PROBLEM INDEED

Owen Flanagan's The Really Hard Problem provides a rich source of reflection on the question of meaning and ethics within the context of philosophical naturalism. I affirm the title's claim that the quest to find meaning in a purely physical universe is indeed a hard problem by addressing three issues: Flanagan's claim that there can be a scientific/empirical theory of ethics (eudaimonics), that ethics requires moral glue, and whether, in the end, Flanagan solves the hard problem. I suggest that he does not, although he provides much that is of importance and useful for further reflection along the way.     

ABOLISHING AND ESTABLISHING OPERATION ANALYSES OF SOCIAL ATTENTION AS POSITIVE REINFORCEMENT FOR PROBLEM BEHAVIOR

Three participants whose problem behavior was maintained by contingent attention were exposed to 45‐min presessions in which attention was withheld, provided on a fixed‐time (FT) 15‐s schedule, or provided on an FT 120‐s schedule. Following each presession, participants were then tested in a 15‐min session similar to the social attention condition of an analogue functional analysis. The results showed establishing operation conditions increased problem behavior during tests and that abolishing operation conditions decreased problem behavior during tests.     

A PRACTICAL STRATEGY FOR ONGOING REINFORCER ASSESSMENT

There is a need for practical methods of reinforcer assessment that systematically track ongoing changes in clients' preferences. In this study, the effects of a time-efficient reinforcer assessment package were evaluated in a multiple baseline across 3 preschoolers with autism, comparing individualized item selections by experienced teachers with children's presession preferences for items of various sensory qualities. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, as well as yielding expected improvements in accuracy. The powerful side-effects of potent reinforcers underline the importance of increased attention to reinforcer assessment in research and practice.     

THE HEADING OF A PROBLEM

Efforts to understand the division between analytic and continental philosophy in strictly philosophical terms seem slated to disappointment. Nevertheless, the worldwide dominance of these two models and their numerous subvarieties is the most salient feature of the passage of philosophy through the twentieth century. This paper explores this dominance and offers an assessment of developments that point toward a change from the model of two models. Specific attention is paid to Jacques Derrida's work on philosophical nationalism, which suggests that this change reflects the growing extension of the English language across the world and, hence, belongs to a profoundly ambiguous development. According to Derrida, on the one hand, this development holds out the chance for something radically nonparochial: “the universal penetration of the philosophical and of philosophical communication,” while on the other hand, it raises the threat that certain forms of “dogmatism and authority” that are linked to particularities of nation and history will impose “an axiomatic of philosophical discourse without any possible discussion.” 1 The future of continental philosophy is assessed in light of this ambiguous development.
