Analysis of proposed three-class classification decision rules in terms of the ideal observer decision rule

We analyze recently proposed decision rules for three-class classification from the point of view of ideal observer decision theory. We consider three-class decision rules proposed by Scurfield, by Chan et al., and by Mossman. Scurfield's decision rule is shown to be a special case of the three-class ideal observer decision rule in three different situations. Chan et al. start with an ideal observer model and specify its decision-consequence utility structure in a way that causes two of the decision lines used by the ideal observer to overlap and the third line to become undefined. Finally, we show that, for a particular and obvious choice of ideal-observer-related decision variables, the Mossman decision rule cannot be a special case of the ideal observer decision rule. Despite the considerable difficulties presented by the three-class classification task, the three-class ideal observer provides a useful framework for analyzing a variety of three-class decision strategies.     

儿童对情绪表达规则的理解与策略的使用

从一所普通小学一三五年级学生中选取90名被试,结构访谈法考察儿童对情绪表达规则的理解与表达策略的使用。结果表明,儿童对情绪表达规则的理解在一到三年级阶段获得快速发展,三到五年级变化很小,而且在积极和消极情境下发展趋势比较一致,但性别和情境交互作用显著。不同年级儿童对策略的使用表现出类似对情绪表达规则理解的变化趋势,全部被试中,平静化策略使用最多,掩饰策略次之,在掩饰策略的使用上,性别和情境交互作用显著。     

青少年自主性发展的特点

从北京地区选取两所中学初一至高二年级1155名学生为被试,采用问卷法来探讨青少年自主性发展的特点。研究共涉及道德、传统、交友、个人、安全5个领域以及家庭规则、父母权威认同和自主行为水平3个层面的内容。结果显示:自主性在整个青少年期呈逐渐增长的趋势。在不同领域中和不同的层面上,各年级不同性别的青少年自主性发展有显著差异。     

审美概念学习效应与迁移的逻辑线路探究

以49名小学四年级学生和30名大学教师及研究生为实验对象,采用SMSD模式进行审美概念学习,结果发现这两组被试的审美理解和感受水平都有显著提高。对大学教师研究生组再作前审美概念(已学概念)之于后审美概念(未学概念)各因素影响情况的回归分析,得到四个回归方程,据此绘制出SMSD模式审美概念学习迁移模型图,归纳出平行迁移、纵向迁移、交叉迁移、小巡回迁移、大巡回迁移等若干逻辑线路。     

The balance beam in the balance: reflections on rules, relational complexity, and developmental processes

The lead articles by Jansen and van der Maas (2002, this issue) and Halford, Andrews, Dalton, Boag, and Zielinski (2002, this issue) raise numerous questions concerning the development of rule use and how best to assess it. In this Reflection, we focus on the following: (a) When can one infer the use of a rule? (b) What are the mechanisms underlying the development of rule use? and (c) What is the relation between understanding and execution? In addressing these questions, we contrast relational complexity theory with cognitive complexity and control (CCC) theory.     

Refutations,Proofs, and Models in the Modal Logic K4

In this paper we study the method of refutation rules in the modal logic K4. We introduce refutation rules with certain normal forms that provide a new syntactic decision procedure for this logic. As corollaries we obtain such results for the following important extensions: S4, the provability logic G, and Grzegorczyk's logic. We also show that tree-type models can be constructed from syntactic refutations of this kind.     

The Pleasures of Anticipation: Enriching Intuitionistic Logic

We explore a relation we call anticipation between formulas, where A anticipates B (according to some logic) just in case B is a consequence (according to that logic, presumed to support some distinguished implicational connective ) of the formula AB. We are especially interested in the case in which the logic is intuitionistic (propositional) logic and are much concerned with an extension of that logic with a new connective, written as a, governed by rules which guarantee that for any formula B, aB is the (logically) strongest formula anticipating B. The investigation of this new logic, which we call ILa, will confront us on several occasions with some of the finer points in the theory of rules and with issues in the philosophy of logic arising from the proposed explication of the existence of a connective (with prescribed logical behaviour) in terms of the conservative extension of a favoured logic by the addition of such a connective. Other points of interest include the provision of a Kripke semantics with respect to which ILa is demonstrably sound, deployed to establish certain unprovability results as well as to forge connections with C. Rauszer's logic of dual intuitionistic negation and dual intuitionistic implication, and the isolation of two relations (between formulas), head-implication and head-linkage, which, though trivial in the setting of classical logic, are of considerable significance in the intuitionistic context.     

The relationship between purposiveness and information integration: The effect of metamotivational states on cognitive rules in sport

IntroductionInformation integration theory is based on an axiom of purposiveness (i.e. cognition is goal-motivated) and on an axiom of integration (i.e. an action or thought depends on the integration of several stimuli). The relationship between the two axioms has not previously been studied.ObjectiveTo explore the influence of metamotivational states on information integration. We looked at how 70 athletes combined four factors (autonomy, relatedness, competence, and the natural environment) when deciding whether or not to get involved in running under paratelic (activity-oriented) and telic (goal-oriented) conditions.MethodThe participants recorded their decision-making processes for two sets of 24 scenarios built from combinations of the four factors. Repeated-measures ANOVAs were applied to the data.ResultsAll four factors were taken into consideration by the participants when deciding whether or not to get involved in running. The participants used a conjunctive rule under the paratelic condition and an additive rule under the telic condition.ConclusionAn individual's metamotivational state may modify the cognitive algebra in information integration. Further research is required to confirm these initial findings.     

Semantic Information and the Syntax of Propositional Attitude Verbs

Propositional attitude verbs, such as think and want, have long held interest for both theoretical linguists and language acquisitionists because their syntactic, semantic, and pragmatic properties display complex interactions that have proven difficult to fully capture from either perspective. This paper explores the granularity with which these verbs’ semantic and pragmatic properties are recoverable from their syntactic distributions, using three behavioral experiments aimed at explicitly quantifying the relationship between these two sets of properties. Experiment 1 gathers a measure of 30 propositional attitude verbs’ syntactic distributions using an acceptability judgment task. Experiments 2a and 2b gather measures of semantic similarity between those same verbs using a generalized semantic discrimination (triad or “odd man out”) task and an ordinal (Likert) scale task, respectively. Two kinds of analyses are conducted on the data from these experiments. The first compares both the acceptability judgments and the semantic similarity judgments to previous classifications derived from the syntax and semantics literature. The second kind compares the acceptability judgments to the semantic similarity judgments directly. Through these comparisons, we show that there is quite fine‐grained information about propositional attitude verbs’ semantics carried in their syntactic distributions—whether one considers the sorts of discrete qualitative classifications that linguists traditionally work with or the sorts of continuous quantitative classifications that can be derived experimentally.
