刺激类型与预先信息对任务切换的影响

为揭示联结竞争与任务设置重构在切换加工过程中的关系,以切换代价为指标,研究了刺激类型与预先信息对任务切换的影响效应,结果发现:(1)无信息的切换代价显著高于部分信息和全部信息的切换代价,而后二者之间无显著差异;(2)单向刺激的切换代价显著高于双向刺激的切换代价;(3)预先信息和刺激类型对切换代价的影响无交互作用。这表明任务设置重构与联结竞争是两个具有相加效应的序列认知活动。     

新的发展模型和价值观念问题

今天,当代文明的发展正处于某种转折点上。这样的想法并不新颖。历史学家、哲学家和社会学家们都曾经提出过这样的论断。只要人类受到了日益恶化的全球性危机的威胁,发展战略就必须改变,这是显而易见的。不过,这里却会出现下列问题：这样的战略变化应当由什么内容构成呢？一般说来,当人们针对这个问题提出各种答案的时候,     

知识类别和特点对内隐序列学习的影响

用序列学习中的反应时和错误个数间接测量被试的内隐知识,用再认成绩和预测成绩直接测量被试的外显知识,通过倒转不同的规则探讨了知识类别和特点对内隐序列学习的影响。结果表明：(1)内隐学习和外显学习可能分别依赖于两个独立的学习系统,且互不干扰;(2)当内隐序列学习既包含运动知识又包含概念知识时,知识类别和特点影响被试对序列知识的获得,被试较易获得运动知识;(3)在内隐序列学习中练习的数量也影响被试对序列知识的获得,序列学习是一个动态的过程。     

笔画类型对直立和倾斜汉字识别的影响

首次用笔画类型概念描述一种汉字整体视觉结构特征。实验采用命名范式。结果发现,汉字无论处于垂直正位下,还是处于以４５°间隔递增的七种倾斜角度下,都存在笔画类型效应。该研究还分析了线条倾斜效应和笔画类型因素在笔画类型效应中的作用     

RADICAL ORTHODOXY AND THE NEW CULTURE OF OBSCURANTISM

Centering around a careful, sustained critique of John Milbank's polemic against Kant, this essay connects the growing anti‐philosophical sentiments in theology to a wider anti‐rational trend in the human sciences generally. What most visibly unifies these new obscurantist outlooks is their reliance on free‐floating, unapologetically self‐perpetuating ideological historiographies, which are advanced via a kind of “co‐opt‐and‐plunder” approach to historical texts. However, the rejection of rational integrity also entails a rejection of the traditional intellectual virtues—attentiveness, consistency, modesty, charity etc.—virtues which any theological claim to orthodoxy cannot do without. Radical Orthodoxy therefore risks a worrying slide into new forms of esoteric gnosticism.     

EFFECT OF STRUCTURAL CUEING AND DECISION TYPE FOR IMPROVING RETENTION OF TECHNICAL TEXT

This study investigated the effects of structural cueing (color or no color) and decision level (rote or semantic) on students' verbatim retention of technical prose. Structural cueing represented the assimilation of encoding hypothesis for improving memory, and decision tasks represented the distinctiveness of encoding hypothesis for promoting deep processing. Subjects read an article on a microcomputer monitor in which either color‐coding or white‐only print was used to represent the structural importance among ideas in each paragraph and then, subsequent to each paragraph, responded to either rote memory or semantic memory decision statements. Results of a free written recall measure using a two‐factor analysis of covariance, revealed significant differences between students' retention on decision type but no differences based on color cueing. That is, students who responded to semantic level decision statements recalled more of the text than those who responded to the rote level decision statements. The results supported the distinctiveness of encoding hypothesis for learning via the microcomputer but did not support the assimilation of encoding hypothesis.     

PSYCHOLOGICAL SEX TYPE AND ANDROGYNY IN THE STUDY OF COMMUNICATION VARIABLES: SELF-DISCLOSURE AND COMMUNICATION APPREHENSION

This study extended the investigation of gender differences in two communication variables, self-disclosure and communication apprehension, by shifting the conceptual focus from the biological sex dichotomy to the more discriminating psychological sex-role designations: masculine, feminine, and androgynous. Using the Bern Sex-Role Inventory (BSRI) as a measure of psychological sex type, the study showed that psychological sex type is superior to biological sex categories in identifying patterns of self-reported self-disclosure and communication apprehension. A number of hypotheses were considered with regard to total disclosure to same-sex friend or opposite-sex friend, and communication apprehension.     

QUANTUM AND CONSCIOUSNESS: IN SEARCH OF A NEW PARADIGM

Abstract. Two fundamental issues raised by Lothar Schäfer are considered: (1) the question of a suitable paradigm within which the findings of quantum physics can be optimally interpreted and (2) the question of the assessment of the presence and importance of mind and consciousness in the universe. In regard to the former, I contend that the ideal of science is to interpret its findings in an optimally consistent and minimally speculative framework. In this context Schäfer's assertion that certain findings in quantum physics (those that relate to virtual states) indicate the presence of mind at the quantum level implies a dualistic and hence unnecessarily speculative assumption. In regard to the assessment of mind and consciousness, a consistent and parsimonious paradigm suggests that mind and consciousness are not part of a chain of events consisting of an admixture of physical and mental events but that physical events form a single, coherent set of events, and mental events another set, with the two sets related, as Teilhard (and a number of other philosophers, including White head) affirmed, as the “within” and the “without” (or the “mental pole” and the “physical pole”) of one and the same fundamental reality. This panpsychist as contrasted with Schäfer's dualist paradigm provides a single self‐consistent framework for the interpretation of quantum (and all natural) events while recognizing the presence of mind in the universe as the least speculative realist implication of our immediate experience of consciousness.     

VALUE SYSTEMS OF STUDENTS IN PAPUA NEW GUINEA AND AUSTRALIA

The Rokeach Value Survey was administered to 12 groups of indigenous respondents fluent in the English language and enrolled in tertiary institutions and training programmes in Papua New Guinea (over 1,100 subjects). Average value systems of these respondents were compared with those of three Australian student groups (secondary and tertiary). Marked differences were found in the relative importance assigned to particular values. Values assigned relatively high importance by the Papua New Guinea groups were discussed in relation to lower-order safety and security needs that may become salient in a developing country, and in terms of the traditional culture and the history of Papua New Guinea, especially the missionary influence, the extended family and wantok (”one-talk”) systems, possible expatriate influence on occupational roles, and present concern with emerging nationhood. Values assigned relatively high importance by the Australian groups were discussed in relation to higher-order needs that might become prepotent in a more affluent society. Factor analyses indicated that all 12 groups in Papua New Guinea were fairly similar in their average value systems.     

THE EFFECTS OF CONSUMER CHARACTERISTICS AND TYPE OF EMPLOYMENT MODEL ON INDIVIDUAL OUTCOMES IN SUPPORTED EMPLOYMENT

Although recent federal legislation has led to a proliferation of supported employment programs throughout the country, little information is available that documents the success of these programs. In the present study, we examined the effect of different consumer characteristics and alternative supported employment service delivery models on key employment outcomes including hourly wage, hours worked per week, increase in earnings after supported employment participation, and level of integration on the job. The employment outcomes of a sample of 1,550 individuals receiving supported employment services through 96 local programs in eight states were analyzed to determine the effects of the key independent variables of primary disability and type of employment model. Results indicate that all groups of individuals, regardless of their primary disability, benefited significantly from supported employment participation. Further, data indicate that the individual placement model generated employment outcomes superior to those resulting from group employment options, particularly work crews. Implications of the results for future program development activities are discussed.
