人工语法学习模型述评

述评了近年来影响较大的四个人工语法学习模型——THIYOS分类器系统、竞争组块模型、范例模型和联系者模型。它们都认为,人工语法学习所获得的知识中,一部分以规则、组块、总体类似性以及激活模式等形式到达意识层面,另一部分则残存在力量模式中,确定什么内容适合到达意识层面;后者即为内隐知识。这四种模型各抒己见,各有特点,并都为内隐学习的机理提供了重要依据。

传统本体论哲学的终结和马克思哲学变革的实质

本文从讨论Ontology的译名开始,主张严格区分作为一门哲学分支学科的“存在论”,和作为一种特定哲学理论形态的“本体论”两个概念;通过对传统西方哲学所代表和象征的哲学理念的把握,揭示了其基本特征和历史命运;进而从马克思哲学与传统西方哲学的否定性关系视角,阐明了马克思哲学变革的实质和意义。作者认为,马克思哲学在哲学史上最具深远意义的革命变革,就在于它通过对传统本体论哲学的批判和超越,开创了哲学发展的新方向．奠定了哲学发展新形态的基础。     

Knowledge partitioning in categorization: constraints on exemplar models

The authors present 2 experiments that establish the presence of knowledge partitioning in perceptual categorization. Many participants learned to rely on a context cue, which did not predict category membership but identified partial boundaries, to gate independent partial categorization strategies. When participants partitioned their knowledge, a strategy used in 1 context was unaffected by knowledge demonstrably present in other contexts. An exemplar model, attentional learning covering map, was shown to be unable to accommodate knowledge partitioning. Instead, a mixture-of-experts model, attention to rules and instances in a unified model (ATRIUM), could handle the results. The success of ATRIUM resulted from its assumption that people memorize not only exemplars but also the way in which they are to be classified.     

Evolved sex differences in the number of partners desired? The long and the short of it

Do men seek more short-term mates than women? Buss and Schmitt (1993) showed a pattern of mean difference in the ideal number of sexual partners men and women desired over various time frames. We replicated these mean sex differences (e.g., ideal number over the next 30 years: Ms = 7.69 and 2.78 for men and women, respectively), but in both data sets the sampling distributions were highly skewed. In Study 1, we found few sex differences in medians across time frames (e.g., ideal number over the next 30 years: Mdn = 1 for both men and women). In Study 2, most college men (98.9%) and women (99.2%) said they wanted to settle down with one mutually exclusive sexual partner at some point in their life, ideally within the next 5 years. Neither medians in number of partners desired overall before settling down (replicating Study 1) nor medians in short-term partners desired before settling down (Mdn = 0) differed significantly by gender. Rather, men and women concurred: Short-term mating is not what humans typically seek.     

Fathering and children's sex role orientation in Korea

The purpose of this exploratory study was to examine variation in aspects of contemporary Korean fathering, such as warmth and involvement (frequency and task share), and its relationship to children's sex role development. One hundred and twenty-nine Korean families (fathers, mothers, and their 11- to 13-year-old children) completed standardized questionnaires addressing child-rearing practices, parental involvement, spousal support, and sex role orientations. Statistical analyses of the data revealed that warmth of fathering and father involvement (frequency and task share) were not significantly associated with children's sex role orientations. However, girls' femininity was significantly related to fathers' masculinity.     

Cognitive stimulation in brainstorming

Research on group brainstorming has demonstrated that it is less effective for generating large numbers of ideas than individual brainstorming, yet various scholars have presumed that group idea sharing should enhance cognitive stimulation and idea production. Three experiments examined the potential of cognitive stimulation in brainstorming. Experiments 1 and 2 used a paradigm in which individuals were exposed to ideas on audiotape as they were brainstorming, and Experiment 3 used the electronic brainstorming paradigm. Evidence was obtained for enhanced idea generation both during and after idea exposure. The attentional set of the participant and the content of the exposure manipulation (number of ideas, presence of irrelevant information) influenced this effect. These results are consistent with a cognitive perspective on group brainstorming.     

Illusions in quantified reasoning: How to make the impossible seem possible, and vice versa

The mental model theory postulates that reasoners build models of the situations described in premises, and that these models normally represent only what is true. The theory has an unexpected consequence. It predicts the existence of illusions in inferences. Certain inferences should have compelling but erroneous conclusions. Two experiments corroborated the occurrence of such illusions in inferences about what is possible from disjunctions of quantified assertions, such as, "at least some of the plastic beads are not red." Experiment 1 showed that participants erroneously inferred that impossible situations were possible, and that possible situations were impossible, but that they performed well with control problems based on the same premises. Experiment 2 corroborated these findings in inferences from assertions based on dyadic relations, such as, "all the boys played with the girls."     

Childhood stress leads to later suicidality via its effect on cognitive functioning

The present study examined the etiology of suicidal behavior from cognitive and developmental perspectives in a sample of 181 suicidal and nonsuicidal college students. We hypothesized that cognitive functioning would serve as a mediator between early life events and suicidal behavior. The present study examined child maltreatment, family instability, and poor general family environment as early negative life events, and examined self-esteem, locus of control, hopelessness, and problem-solving deficits as cognitive factors. In addition, individuals' perceived social support before age 18 and current social support and life stress were also examined in relation to the preceding variables. A series of structural equation analyses indicated that early negative life events have a mild impact on suicidal behavior, but a stronger impact on cognitive deficits, which in turn have a strong impact on suicidal behavior.
