The concurrent validity and test–retest reliability of a visuospatial working memory task

To determine whether the visuospatial n-back working memory task is a reliable and valid measure of cognitive processes believed to underlie intelligence, this study compared the reaction times and accuracy of performance of 70 participants, with performance on the Multidimensional Aptitude Battery (MAB). Testing was conducted over two sessions separated by 1 week. Participants completed the MAB during the second test session. Moderate test–retest reliability for percentage accuracy scores was found across the four levels of the n-back task, whilst reaction times were highly reliable. Furthermore, participants' performance on the MAB was negatively correlated with accuracy of performance at the easier levels of the n-back task and positively correlated with accuracy of performance at the harder task levels. These findings confirm previous research examining the cognitive basis of intelligence, and suggest that intelligence is the product of faster speed of information processing, as well as superior working memory capacity.     

What we must Accomplish in the coming Decades

Abstract. In order to survive as a species and grow in complexity, humanity must adopt a new image of what it means to be human, rediscover a reward system beyond the merely material, and see that young people find joy in challenges and in cooperating with others.     

On Different Proof-Search Strategies for Orthologic

In this paper, we consider three different search strategies for a cut-free sequent system formalizing orthologic, and estimate the respective search spaces. Applying backward search, there are classes of formulae for which both the minimal proof length and the search space are exponential. In a combined forward and backward approach, all proofs are polynomial, but the potential search space remains exponential. Using a forward strategy, the potential search space becomes polynomial yielding a polynomial decision procedure for orthologic and the word problem for free ortholattices.     

Risk and Religion: Toward a Theology of Risk Taking

Historically the concept of risk is rooted in Renaissance lifestyles, in which autonomous agents such as sailors, warriors, and tradesmen ventured upon dangerous enterprises. Thus, the concept of risk inseparably combines objective reality (nature) and social construction (culture): Risk = Danger + Venture. Mathematical probability theory was constructed in this social climate in order to provide a quantitative risk assessment in the face of indeterminate futures. Thus we have the famous formula: Risk = Probability (of events) × the Size (of future harms). Because the concept of harm is always observer relative, however, risk assessment cannot be purely quantitative. This leads to the question, What are the general conditions under which risks can be accepted? There is, after all, a difference between incurring a risk and bearing the costs of risks selected for by other agencies. Against this background, contours of a theology of risk emerge. If God creates a self‐organizing world of relatively autonomous agents, and if self‐organization is favored by cooperative networks of autopoietic processes, then the theological hypothesis of a risk‐taking God is at least initially plausible. Moreover, according to the Christian idea of incarnation, God is not only taking a risk but is also bearing the risks implied by the openness of creation. I thus argue for a twofold divine kenosis—in creation as well as in redemption. I discuss some objections to this view, including the serious counterargument that risk taking on behalf of others remains, even for God, a morally dubious task. What are the conditions under which the notion of a risk‐taking God can be affirmed without leaving us with the picture of God as an arbitrary, cosmic tyrant? And what are the practical implications for the ways in which human agents of faith, hope, and love can learn to cope with the risks of everyday life and of political decisions?     

Moral Lumps

Can all goods or bads be broken down into smaller and smaller pieces? Can all goods or bads be added together with some other good or bad to get a larger amount? Further, how does moral significance track the disaggregation and the aggregation of moral goods and bads? In Part 1, I examine the limits placed on aggregation by moderate deontological moral theories. This paper focuses in particular on the work of Judith Thomson and T.M. Scanlon as well as on some of my own past work on the question of aggregation in the context of overriding rights. In Part 2, I examine consequentialist criticism that harms and benefits can be broken down into smaller pieces than the deontological theory allows and the argument that the moderate deontological view is too permissive since it allows aggregation of benefits within a single person's life. In Part 3 I suggest how a moderate deontological moral theory might respond to the criticisms. I cast my answer in terms of the existence of lumpy goods and bads. I argue that consequentialist critics of deontology are wrong to insist that all goods and bads can be disaggregated and aggregated at will. Instead, I offer the suggestion that most, or many, goods and bads come in morally significant lumps. That said, it will not always be obvious what those lumps are. Determining the texture of moral value is a substantive project in normative ethics. All I have hoped to do in this paper is suggest that two standard positions on how to group moral value are mistaken and give hope that we need not adopt one of the two. Part 4 of the paper responds to an objection and sets the stage for further work in value theory.     

QUANTUM REALITY,THE EMERGENCE OF COMPLEX ORDER FROM VIRTUAL STATES,AND THE IMPORTANCE OF CONSCIOUSNESS IN THE UNIVERSE

Abstract. I review some characteristic aspects of quantum reality and make the connection to Pierre Teilhard de Chardin's vision and a generally new quantum perspective of biological evolution. The quantum phenomena make it possible to conclude that the basis of the material world is nonmaterial; that the nature of reality is that of an indivisible wholeness; and that elementary particles possess aspects of consciousness in a rudimentary way. The quantum perspective of evolution makes it possible to conclude that the emergence of complex order in the biosphere is not from nothing (ex nihilo) but by the actualization of virtual quantum states—that is, by actualizing empty states which are part of the mathematical structure of material systems, representing a logical order that is not real in a material sense but, predetermined by system conditions, has the potential to become real in quantum jumps. I show how the existence of virtual states makes it possible to suggest that a transcendent reality underlies the visible order of the world and is immanent to it; and constantly new forms evolve from it.     

Computing with Cylindric Modal Logics and Arrow Logics,Lower Bounds

The complexity of the satisfiability problems of various arrow logics and cylindric modal logics is determined. As is well known, relativising these logics makes them decidable. There are several parameters that can be set in such a relativisation. We focus on the following three: the number of variables involved, the similarity type and the kind of relativised models considered. The complexity analysis shows the importance and relevance of these parameters.     

Development and Disequilibration: Predicting Counselor Trainee Gain and Loss Scores on the Supervisee Levels Questionnaire

Relative importance of adult cognitive development (according to Perry), education, and experience in predicting longitudinal gain and loss scores on a measure of counselor supervisee development (Supervisee Levels Questionnaire) was examined. Results indicated cognitive & #x2013;developmental stage predicted score change better than age, education, or experience. In addition, an unanticipated, discontinuous, patterned relationship between student cognitive stage and the gain/loss scores was discovered. The possibility of developmental disequilibration is discussed along with implications for counselor education and adult development theory.     

问题解决中图式与策略的关系:来自表征复杂性模型的说明

采用口语报告法收集了26名小学三年级儿童解决两道复杂的算术应用题时的口语报告和作业资料,探讨了问题解决中图式与策略的关系。结果发现,对二者关系的解释要以问题表征复杂性为中介：如果被试的关系图式水平较高,表征复杂性(特别是表征深度)也会较大,相应会选择领域专门性更强的快捷策略;如果缺乏必需的关系图式。表征深度就降低,甚至不能正确表征问题,这时只好使用常规策略甚至错误策略。这个结论适用于有多种表征和解题方式的问题中。
