在推理加工能力上学困生与学优生的比较研究

本研究采用模糊集论和信息论的方法,探讨了中小学学困生与学优生在不同记忆负荷条件下的推理加工。结果表明,学优生与学困生在高低两种记忆负荷条件下,已知信息的利用率和推理加工的效率都受到了影响。其中学困生的已知信息的利用率不如学优生,学困生的推理加工效率也不如学优生。     

怒族、傈僳族和景颇族儿童认知发展研究

采用《中小学生思维发展水平测验量表》,对怒族、傈僳族和景颇族三种少数民族390名儿童进行调查研究。结果发现：1．儿童认知发展的阶段性基本支持皮亚杰认知发展的阶段性理论,形式思维水平在13～16岁尚未形成稳定的认知结构;2．在发展的年龄上,儿童认知发展水平出现明显的“滞后”现象;3．儿童在初中一年级出现认知发展的加速期;4．三种少数民族儿童认知发展整体上不存在显著性的跨文化差异;5．认知发展在性别差异上主要体现在动作协调一空间定位能力上。     

西方语言产生研究中的几个主要问题

文章对西方语言产生这一领域的研究传统与近年来的一些主要研究成果进行了一个小结,整个小结分4个部分:(1)语言产生的研究传统;(2)现代西方心理语言学研究的范式;(3)语言产生的加工阶段;(4)目前的主要理论模型及其争论。文章的主要目的是总结西方语言产生研究的进程、方法与理论争论,为汉语语言产生的研究提供借鉴。     

善的两种冲突

冲突一词在语言表达中其实有两个很不相同的意义和用法。一种用法是：冲突的命题不能同时为真的逻辑真理性冲突;另一种用法是：冲突的价值欲望不能同时满足的现实选择性冲突。本文对冲突的两种意义及用法进行了区别,分析了这两种冲突的意义和用法在道德善恶判断中的联系和混用,并对道德相对主义与道德多元主义提出了批评。     

Are transitions in human gait determined by mechanical,kinetic or energetic factors?

It is currently unclear whether it is the need to maintain metabolic efficiency, the need to keep skeletal loading below critical force levels, or simple mechanical factors that drive the walk-to-run (W-R) and run-to-walk (R-W) transitions in human gait. Eighteen adults (9 males and 9 females) locomoted on an instrumented treadmill using their preferred gait. Each completed 2 ascending (W-R) and 2 descending (R-W) series of trials under three levels of loading (0%, 15% and 30% body weight). For each trial, participants locomoted for 60 s at each of 9 different speeds--4 speeds both above and below their preferred transition speed (PTS) plus their PTS. Evidence was sought for critical levels of key kinetic (maximum vertical force, impulse, first peak force, time to first peak force and maximum loading rate), energetic (oxygen consumption, transport cost) and mechanical variables (limb lengths, strength) predictive of the gait transition. Analyses suggested the kinetic variables of time to first peak force and loading rate as the most likely determinants of the W-R and R-W transitions.     

Process dissociation as source monitoring

A 2-high-threshold model source-monitoring model (U. J. Bayen, K. Murnane, & E. Erdfelder, 1996) was applied to both source-monitoring and process-dissociation data collected varying source and distracter similarity. The model fit both sets of data using identical parameter values. The values of the detection parameter, D, and the source-discrimination parameter, d, varied in the manner expected. Also, neither the process-dissociation (L. L. Jacoby, 1991) nor the extended process-dissociation model (A. Buchner, E. Erdfelder, & B. Vaterrodt-Plünnecke, 1995) fit either type of data. The memory processes involved in recognition judgments are the same when using the process-dissociation or the source-monitoring procedure. The 4 cognitive processes in both procedures can be interpreted as item detection, source identification, recognition guessing, and source guessing. The potential role of unconscious memory influences via the 2 guessing processes is discussed.

Behavioral and developmental consequences of early rearing experience for captive giant pandas (Ailuropoda melanoleuca)

Mother-reared (MR) and peer-reared (PR) captive giant panda (Ailuropoda melanoleuca) cubs were compared to evaluate the effects of early removal from mother on behavioral development. Males and females and twins and singletons were compared to assess the effects of social setting on behavioral development. Subjects included 2 PR females, 3 MR females, 3 MR males, and 3 mothers. MR cubs spent more time manipulating bamboo and fell more often than PR cubs. PR cubs spent more time inactive. Male cubs directed more playful behavior at their mothers. Twins spent more time play fighting with their mothers than with their siblings. The results suggest that peer-rearing does not provide young pandas with the same level of social stimulation as mother-rearing.     

Developmental differences in children's ballistic aiming movements of the arm

An experiment was conducted to examine the change in the relation between programming and "on-line" correction as a developmental explanation of children's arm movement performance. Each of 54 children in three age groups (5, 8, and 10 yr.) completed two types of rapid aiming arm movements in the longitudinal plane on the surface of a digitizer. Percent primary submovements and timing variability were dependent variables. Analysis suggested that the 5-yr.-olds used "on-line" monitoring during the arm movement and did not perform the movement sequence as a functional unit. Compared with 8- and 10-yr.-olds, the 5-yr.-olds planned a smaller portion of movements, executed the arm movements with more variability in time to peak velocity. The 8- and 10-yr.-olds appeared to plan their movements and execute the sequence as a unit. The developmental implications were discussed.     

Factor structure of the strong interest inventory with a Chinese high school sample

D. S. Goh and J. Yu (2001) translated the Strong Interest Inventory (SII; L. W. Harmon, J-I. Hansen, F. H. Borgen, & A. L. Hammer, 1994) into Chinese and identified a 6-factor structure of the new instrument that showed both similarities and differences with J. L. Holland's personality types (1966, 1985, 1997). The present study was undertaken to further investigate the construct validity of the SII-Chinese for a sample of 247 high school students in China. Confirmatory factor analyses did not find a good fit of the Goh and Yu (2001) model or the Holland hexagonal model to the present data. Exploratory factor analysis extracted a 3-factor solution accounting for 59.2% of the variance. The authors offer interpretations of the obtained factors and discuss implications for the use of the SII-Chinese as an assessment tool.
