A connectionist model of a continuous developmental transition in the balance scale task

A connectionist model of the balance scale task is presented which exhibits developmental transitions between ‘Rule I’ and ‘Rule II’ behavior [Siegler, R. S. (1976). Three aspects of cognitive development. Cognitive Psychology,8, 481–520.] as well as the ‘catastrophe flags’ seen in data from Jansen and van der Maas [Jansen, B. R. J., & van der Maas, H. L. J. (2001). Evidence for the phase transition from Rule I to Rule II on the balance scale task. Developmental Review, 21, 450–494]. The model extends a connectionist model of this task [McClelland, J. L. (1989). Parallel distributed processing: Implications for cognition and development. In R. G. M. Morris (Ed.), Parallel distributed processing: Implications for psychology and neurobiology (pp. 8–45). Oxford: Clarendon Press] by introducing intrinsic variability into processing and by allowing the network to adapt during testing in response to its own outputs. The simulations direct attention to several aspects of the experimental data indicating that children generally show gradual change in sensitivity to the distance dimension on the balance scale. While a few children show larger changes than are characteristic of the model, its ability to account for nearly all of the data using continuous processes is consistent with the view that the transition from Rule I to Rule II behavior is typically continuous rather than discrete in nature.     

纵向再探学前儿童心理理论发展模式

本文作者前不久完成的一项横断设计研究中, 以自编的心理理论量表测查比较了中美两国3~5岁儿童的有关发展。量表包括五项任务: (1) 不同的愿望; (2) 知与不知; (3) 不同的信念; (4) 内容错误信念和 (5) 伪装的情绪。研究发现两种不同文化群体儿童对上述任务的理解均表现出稳定一致的发展次序, 两者的次序大致相同但具有重要差别: 我国儿童的理解次序如从易到难排列如上所列, 这一次序与美国儿童的差别在于我国儿童先理解“知与不知”, 然后是“不同的信念”, 而美国儿童则恰好相反。这一研究结果对了解不同文化儿童心理理论的发展次序是十分有意义的, 但问题是经由横断设计的量表研究所确立的发展次序能否准确地描述个体儿童的纵向进展呢? 为此本研究使用了相同的测量工具对参加过横断研究的北京3岁儿童(时间1)在他们4岁(时间2)和5岁(时间3)时进行了焦点追踪研究。研究结果表明, 随着测查时间的 延伸, 个体儿童的作业成绩不仅逐步提高, 而且这种提高符合量表任务的发展次序。通过应用格特曼(Guttman)和雷氏(Rasch)测量模型对这一结果的分析, 再一次证实我国个体儿童的有关发展次序与欧美文化儿童的发展次序大致相同并且有重要的差别。本研究的结果不仅能为横断研究中个别差异的研究提供有用的工具, 而且深化了人们对心理理论发展机制的认识, 即把心理理论的发展看作是在一定的文化环境影响下不断扩展和深化的概念建构过程。但对这一推论仍有待进一步证实。

Rule transition on the balance scale task: a case study in belief change

For various domains in proportional reasoning cognitive development is characterized as a progression through a series of increasingly complex rules. A multiplicative relationship between two task features, such as weight and distance information of blocks placed at both sides of the fulcrum of a balance scale, appears difficult to discover. During development, children change their beliefs about the balance scale several times: from a focus on the weight dimension (Rule I) to occasionally considering the distance dimension (Rule II), guessing (Rule III), and applying multiplication (Rule IV; Siegler, 1981). Because of the detailed empirical findings the balance scale task has become a benchmark task for computational models of proportional reasoning. In this article, we present a large empirical study (N = 420) of which the findings provide a challenge for computational models. The effect of feedback and the effect of individually adapted training items on rule transition were tested for children using Rule I or Rule II. Presenting adapted training items initiates belief revision for Rule I but not for Rule II. The experience of making mistakes (by providing feedback) induces a change for both Rule I and Rule II. However, a delayed posttest shows that these changes are preserved after 2 weeks only for children using Rule I. We conclude that the transition from Rule I to Rule II differs from the transition from Rule II to a more complex rule. Concerning these empirical findings, we will review performance of computational models and the implications for a future belief revision model.

位置提示下视觉注意范围的调控机制

研究视觉空间注意中不同注意范围引起脑内加工时程的动态变化。使用固定位置的、三种不同直径的线圈作为注意范围的位置性提示,祛除空间定位因素的影响,记录反应时和事件相关电位（ERP）数据。结果显示：在同等注意范围时,随着刺激位置远离视野中心,反应时延长,靶刺激诱发的P1、N1不受刺激位置的影响,而其前部N2的波幅明显受到刺激位置的影响;在靶刺激位置相同时,随着注意范围的扩大,反应时缩短,靶刺激诱发的P1、N1不受提示范围大小的影响,而其前部P2的波幅明显受到注意范围的影响。结果说明：①视觉注意范围信息加工与靶刺激诱发的P2成分相关;②视觉注意诱发的P1、N1成分,主要与注意方位相关,而与注意范围大小无关;③注意范围变化引起注意集中度的调节是在一定范围内进行的。     

范式转换与道德生活史的研究

伦理学就是一种生活观。伦理思想史的研究需要范式的转换,即由思想史转向道德生活史,研究社会变迁视野中的道德变迁,研究具体历史条件下的社会伦理关系,研究民众层面的日常道德生活。     

Bowen家庭治疗模式评析

和其它经典的家庭治疗一样,Bowen家庭治疗模式也建立在系统理论的基础之上。他认为,个人症状的出现,在于个人与家庭情感的融合而使自己丧失了自我判断和选择的能力。因此,主张用代际互动疗法来解构病态的三角关系,增加与扩大家庭中的互动,从而增强个体的自我分化程度,以减轻焦虑。     

Researchers discover what they already knew about validity: The case of the family-of-Origin Scale

This article is concerned with two recnet studies of the Family-of-Origin Scale (FOS), Gavin and Wamboldt (1992) and Ryan, Kawash, Fine, and Powel (1994). The external validity analyses conducted for the FOS in these studies assumed the scale to be a unidemsional measure. The present discussion centers on methodological decisions and interpretive strategies that may have prevented a more complete understanding of the scale's dimensional structure and theoretical meaning. It is concluded that a unidimensional view of the FOS is an oversimplification that is inconsistent with the available data. A case is made for a more comprehensive and technically adequate evaluation of the FOS. Specific suggestions are offered.
