MOVEMENT SUPPRESSION TIME-OUT FOR UNDESIRABLE BEHAVIOR IN PSYCHOTIC AND SEVERELY DEVELOP MENTALLY DELAYED CHILDREN

The effects of a movement suppression time-out, which involved punishing any movement or verbalization while a client is in the time-out area, were evaluated in four experiments. The first experiment examined the effects of a DRO procedure and movement suppression plus DRO in suppressing self-injurious behavior in a psychotic child in three different situations. In Experiment 2, the results of the previous experiment were replicated with two dangerous behaviors in a second psychotic child. In a third experiment, movement suppression plus DRO was compared with contingent restraint in reducing inappropriate poking behavior in two settings. The movement suppression procedure eliminated poking whereas contingent restraint had little effect. In the final experiment, movement suppression time-out alone was compared with exclusionary time-out alone and simple corner time-out alone. Self-stimulation occurred at high levels during the exclusionary and simple corner time-out procedures. Self-stimulation was either suppressed or reduced during movement suppression time-out. The movement suppression time-out procedure produced a larger reduction in the target behavior in all three children. The effectiveness of the movement suppression procedure was explained in terms of the suppression of self-stimulation while the time-out procedure was being applied.     

A THEORETICAL APPRECIATION OF THE ETHIC OF SOLIDARITY IN POLAND TWENTY-FIVE YEARS AFTER

The remarkable movement known as Solidarity recently celebrated its twenty‐fifth anniversary in Poland. This essay provides a theoretical appreciation of the values and principles that guided and undergirded the movement, which greatly contributed to the fall of communism in Central and Eastern Europe. This systematic overview of the ethic of the Solidarity movement fills a lacuna in the field of ethics because ethicists who are interested in the concept of solidarity have largely overlooked the Polish experience of the 1980s. This essay attempts to describe the key ingredients of the Polish ethic of solidarity by analyzing both Polish treatises on the subject and accounts of events on the ground. It elaborates conceptual categories and describes characteristic features of the movement in order to provide a phenomenological account of the nature of solidarity embodied in Poland during this era. These categories and characteristics include unity among differences, the foundation of hope at the movement's roots, self‐sacrifice and heroism, promoting the equality and dignity of all, the centrality of participation, the affirmation of “bread and freedom,” an option for the poor, and the insistence on life in truth. Although this essay does not attempt to demonstrate the relevance of this “thick” ethic of solidarity to capitalist, democratic societies today, by way of conclusion it raises questions pertaining to the contemporary significance of the Polish ethic of solidarity.     

当前阅读眼动研究的几个主要问题

当前阅读眼动研究主要想解决以下几个问题：（1）阅读中的眼动主要受语言的低水平因素影响还是受语言的高水平因素影响;（2）眼跳过程中信息加工是完全被抑制还是部分被抑制;（3）眼动过程中词义的加工方式是平行的还是系列的。     

阅读过程的眼动理论综述

该文介绍了解释阅读过程的主要眼动理论,并对早期的视觉缓冲器加工理论、直接假说和眼-脑假说、聚光灯理论、Morrison的眼动理论模型等眼动理论和新近的战略战术模型和E-Z模型等眼动理论进行了评述。最后,对眼动理论的发展方向进行了展望。     

工作记忆、表达方式和同质性对线性三段论推理影响的眼动研究

采用眼动记录法,探讨了工作记忆、两个前提间的关系以及表达方式对线性三段论推理的影响。本实验采用2（表达方式：肯定、否定）×2（前提间的关系：同质、不同质）×2（工作记忆容量：高、低）的混合设计。通过分析总注视时间、第一次注视时间、第二次注视时间和回视,发现线性三段论推理过程既有语言加工的参与又有表象加工的参与。推理过程中的语言表征过程和空间关系的建立都受到工作记忆容量的影响,被试的工作记忆容量越高,就越容易建立语言表征和空间的关系。     

马克思的"感性世界"理论与现象学运动

The epistemological problems that are implicit in Marx’s theory on the “sensible world” indicate that Marx’s philosophy in fact contains within itself the topics of pure philosophy, but Marx did not involve himself in these topics. Through comparing with Husserl’s epistemological critique and Heidegger’s existentialism, we can clearly see that there are theoretical spaces in which we can develop Marx’s philosophy to the realm of pure philosophy, however, we must devote our creative efforts to the exploration of the spaces.

Temporal predictive mechanisms modulate motor reaction time during initiation and inhibition of speech and hand movement

Skilled movement is mediated by motor commands executed with extremely fine temporal precision. The question of how the brain incorporates temporal information to perform motor actions has remained unanswered. This study investigated the effect of stimulus temporal predictability on response timing of speech and hand movement. Subjects performed a randomized vowel vocalization or button press task in two counterbalanced blocks in response to temporally-predictable and unpredictable visual cues. Results indicated that speech and hand reaction time was decreased for predictable compared with unpredictable stimuli. This finding suggests that a temporal predictive code is established to capture temporal dynamics of sensory cues in order to produce faster movements in responses to predictable stimuli. In addition, results revealed a main effect of modality, indicating faster hand movement compared with speech. We suggest that this effect is accounted for by the inherent complexity of speech production compared with hand movement. Lastly, we found that movement inhibition was faster than initiation for both hand and speech, suggesting that movement initiation requires a longer processing time to coordinate activities across multiple regions in the brain. These findings provide new insights into the mechanisms of temporal information processing during initiation and inhibition of speech and hand movement.     

汉语阅读中的心理词加工

通过两项研究考察了汉语阅读中心理词存在的心理现实性及其加工效率问题。研究1采用词切分任务考察语法知识掌握水平不同的读者词切分的差异,发现他们在词切分上存在很大分歧,语法知识越丰富,词切分差异越小。研究2探讨心理词的加工效率,使用阴影标记目标词,产生四种呈现条件：正常条件、词汇词条件、心理词条件和非词条件,结果发现心理词比词汇词、非词更容易加工。两项研究结果表明汉语阅读的基本信息单元更可能是心理词。     

Wittgenstein and the Phenomenological Movement: Reply to Monk

Abstract

Monk’s ‘The Temptations of Phenomenology’ examines what the term ‘Phänomenologie’ meant for Wittgenstein. Contesting various other scholars, Monk claims that Wittgenstein’s relation to ‘Phänomenologie’ began and ended during 1929. Monk only partially touches on the question of Wittgenstein’s relation to the phenomenological movement during this time. Though Monk does not mention this, 1929 was also the year in which Ryle and Carnap turned their critical attention toward Heidegger. Wittgenstein also expressed his sympathy for Heidegger in 1929. Furthermore, though in 1929 Wittgenstein agrees with the early Husserl on relating logic and science to phenomenology, it is not clear that they mean the same thing by either logic or phenomenology, or that they agree on what the relation between the two should be.     

Contextual Interference in Movements of the Same Class: Differential Effects on Program and Parameter Learning

Contextual interference effects in motor learning usually were not found when the tasks to be learned presumably required the same generalized motor program (GMP) and differed only with regard to the movement parameters (see Lee, Wulf, & Schmidt, 1992; Magill & Hall, 1990). Thus, tasks requiring different motor programs (e.g., different relative timings) seemed to be a prerequisite for random practice to be more effective than blocked practice. However, the previous studies (that did not find random/blocked differences) used global error measures that confounded errors in relative timing and errors in absolute timing. In the present study, subjects practiced three movement patterns that had the same relative timing (requiring the same GMP) but different overall durations (requiring different parameters). Errors in relative timing and in absolute timing were assessed separately. The results indicate that random practice is more effective for the learning of relative timing (GMP learning) and less effective for the learning of absolute timing (parameter learning) than blocked practice. Preliminary ideas as to the reasons for this effect are discussed.
