Monkeys match and tally quantities across senses

We report here that monkeys can actively match the number of sounds they hear to the number of shapes they see and present the first evidence that monkeys sum over sounds and sights. In Experiment 1, two monkeys were trained to choose a simultaneous array of 1-9 squares that numerically matched a sample sequence of shapes or sounds. Monkeys numerically matched across (audio-visual) and within (visual-visual) modalities with equal accuracy and transferred to novel numerical values. In Experiment 2, monkeys presented with sample sequences of randomly ordered shapes or tones were able to choose an array of 2-9 squares that was the numerical sum of the shapes and sounds in the sample sequence. In both experiments, accuracy and reaction time depended on the ratio between the correct numerical match and incorrect choice. These findings suggest monkeys and humans share an abstract numerical code that can be divorced from the modality in which stimuli are first experienced.     

Antecedent-Relative Comparative World Similarity

In “Backward Causation and the Stalnaker–Lewis Approach to Counterfactuals,” Analysis 62:191–7, (2002), Michael Tooley argues that if a certain kind of backward causation is possible, then a Stalnaker–Lewis comparative world similarity account of the truth conditions of counterfactuals cannot be sound. In “Tooley on Backward Causation,” Analysis 63:157–62, (2003), Paul Noordhof argues that Tooley’s example can be reconciled with a Stalnaker–Lewis account of counterfactuals if the comparative world similarity relation on which the Stalnaker–Lewis account relies is allowed to be antecedent-relative. In this paper I show that taking comparative world similarity to be antecedent-relative results in a formal semantics which is a comparative world similarity semantics in name only.     

正误样例组合学习的相似性效应和认知加工深度效应

为了考察物体受力分析图正、误样例的相似程度以及被试对错误受力分析的认知加工(即对错误受力分析的辨别、解释和改正)水平对物体受力分析规则正误样例组合学习迁移效果的影响,以初中三年级学生为被试进行两项实验研究。实验结果表明:在物体受力分析图正误样例组合学习中存在明显的相似性效应,即正、误样例的相似程度越高,学习迁移的效果越好;对错误受力分析进行"改正"加工的学习迁移效果明显优于对错误的"辨别"加工,即存在明显的认知加工深度效应。     

关于中日大学生精制化活动的比较研究

本研究以中日两国大学生为对象,针对精制化的有关问题进行了跨文化的比较研究。研究表明中国大学生在精制化三个因子的得分显著高于日本大学生;中国大学生的精制化活动表现出性别差异,其中女生比男生的精制化活动更为积极,但日本的大学生却无此种性别差异的表现。     

Customer Service Orientation in Managerial and Non-Managerial Employees: An Exploratory Study

The customer service orientation of managerial and non-managerial employees from a large financial services organization were compared using the Customer Service Skills Inventory (CSSI). The results indicated that, in comparison to non-managerial employees, managers scored significantly higher on Pressure Tolerance, Independent Judgment, and Responsiveness, and significantly lower on Realistic Orientation.     

Hypocrisy, Change of Mind, and Weakness of Will: How to Do Moral Philosophy with Examples

What are the differences between hypocrisy, change of mind, and weakness of will? Each typically involves a gap between word and deed, yet they do not seem morally equivalent. Moreover, they are intuitively different concepts, even though the conceptual boundaries between them are fuzzy. This paper explores diverse examples, attempting to identify elements which may be distinctive of each concept, with special attention to hypocrisy. It also provides a discussion of the appropriateness of such use of examples in moral philosophy.

From Brouwerian Counter Examples to the Creating Subject

The original Brouwerian counter examples were algorithmic in nature; after the introduction of choice sequences, Brouwer devised a version which did not depend on algorithms. This is the origin of the creating subject technique. The method allowed stronger refutations of classical principles. Here it is used to show that negative dense subsets of the continuum are indecomposable.     

Human symbol manipulation within an integrated cognitive architecture

This article describes the Adaptive Control of Thought–Rational (ACT–R) cognitive architecture (Anderson et al., 2004; Anderson & Lebiere, 1998) and its detailed application to the learning of algebraic symbol manipulation. The theory is applied to modeling the data from a study by Qin, Anderson, Silk, Stenger, & Carter (2004) in which children learn to solve linear equations and perfect their skills over a 6-day period. Functional MRI data show that: (a) a motor region tracks the output of equation solutions, (b) a prefrontal region tracks the retrieval of declarative information, (c) a parietal region tracks the transformation of mental representations of the equation, (d) an anterior cingulate region tracks the setting of goal information to control the information flow, and (e) a caudate region tracks the firing of productions in the ACT–R model. The article concludes with an architectural comparison of the competence children display in this task and the competence that monkeys have shown in tasks that require manipulations of sequences of elements.
