Infantile handling and sex as determinants of the negative reinforcing effects of gentling

Summary BD IX rats were trained to avoid a black and white compartment which was associated with gentling. The rats were given 12 acquisition sessions in which they were stroked if they remained in the critical compartment at the end of the fifteen 20-sec intervals during the 5-min test period. The results indicated that the negative reinforcing effects of gentling were a function of the early handling history and sex of the rat.This research was aided by Grant APA-247 from the National Research Council of Canada. The author thanks David Wood for his active collaboration in conducting the experiment.     

Infantile handling and the extinction of responses acquired under food reward

A comparison was made of the runway behaviour of rats which had been handled from Days 1-21 and their non-handled litter mates. The training began on Day 70 after the animals were habituated to a restricted food schedule for 10 days. The subjects were given six trials each day in the runway and were rewarded with a 0.045 g. Noyes pellet. After 10 days of rewarded training trials, subjects were given 6 extinction trials a day for 10 days. Results showed that handled rats ran faster than non-handled rats during acquisition and during the first 3 days of extinction. The extinction data suggested that the relationship between emotionality and effects of frustrative non-reward should be re-evaluated.

Holes and wholes: a reply to Rubin and Kanwisher

This paper, contrary to skepticism about the human ability to perceive topological properties, addresses some commonly heard nontopological counterexplanations and provides evidence to rule out these apparent counterexamples against the topological hypothesis. Data from improved control conditions show that the reason why these counterexamples seem inconsistent with the topological hypothesis is that they fail to take due account of two factors: visibility, and organization other than physical connectedness.     

Lexical processing in a non-native language: Effects of language proficiency and learning strategy

In three experiments, native Chinese speakers were asked to use their native and non-native languages to read and translate Chinese words and to name pictures. In Experiment 1, four groups of subjects with various degrees of proficiency in their second language, English, participated. In Experiments 2 and 3, subjects were first asked to learn a list of words in a new language, French, using either Chinese words or pictures as media; then they performed the reading, naming, and translation tasks. All subjects performed better in reading words than in naming pictures, when responding in Chinese. When the response was in the non-native language (English or French), high-learning subjects were equally efficient in translation and picture-naming tasks. Low-learning subjects, however, performed better in either the translation or the picture-naming task, depending on their learning strategies. These results are consistent with the idea that both proficiency in a non-native language and the strategy for acquiring the language are main determinants for the pattern of lexical processing in that language.     

A further validation of the bem sex role inventory: A multitrait-multimethod study

The present study used a multitrait-multimethod technique [D.T. Campbell and D. W. Fiske (1959) “Convergent and Discriminant Validation by the Multitrait-Multimethod Matrix,” Psychological Bulletin, 56, 81–105] to examine Bem's [(1974) “The Measurement of Psychological Androgyny,” Journal of Consulting and Clinical Psychology, 42, 152–162] use of an instrumental-expressive dichotomy to conceptualize the Masculinity and Femininity scales of the Bem Sex Role Inventory as statistically orthogonal constructs. Results indicate that while perhaps reliable, masculinity and femininity lack clear convergent and discriminant validity. Therefore, Bem's contention that masculinity and femininity are orthogonal constructs is questioned. Results are discussed in light of trait- vs. method-driven research.     

句子理解的实验研究

在三种不同的条件下,对人验证句子的过程作了比较研究。结果表明,无论在哪种条件下,验证不同类型句子的时间模式是一致的。在句子-图形验证任务中,不管这些图形是抽象的符号还是与常识有关的具体事物的图形,其加工所需的时问基本上是相同的。但是,句子-常识验证所需的时间,要比句子-图形验证的时间明显地短。实验还表明,否定词在句中的位置,对句子的理解有一定的影响。     

特殊青少年感觉寻求特质的研究

本文对优秀少年、少年犯和普通少年进行了感觉寻求特质、认知复杂性、棒框测验和心率的研究。旨在检验和证实F.Farley的有关理论:高感觉寻求者由于寻求刺激方式的不同而具有两种不同的行为倾向;并深入探讨不同少年的认知和生理特点。实验结果表明,少年犯和优秀少年比普通少年具有更高的感觉寻求倾向。优秀少年和少年犯寻求刺激的方面是不同的。优秀少年的认知复杂性分数较高,并倾向于场独立性特征,对新异刺激倾向于朝向反射特点;少年犯则具有较低的认知复杂性和场依存性特征。     

Computational and reasoning abilities in arithmetic: Cross-generational change in China and the United States

A Chinese advantage over Americans was found for economically relevant computational and reasoning abilities in arithmetic for groups of 6th- and 12th-grade students matched or equated on general intelligence. No cross-national difference for computational or reasoning abilities was found for samples of older (60- to 80-year-old) Chinese and American adults equated on general intelligence. The pattern of change in arithmetical competencies across cohorts suggests that the Chinese advantage in 6th and 12th grade is due to a cross-generational decline in competencies in the United States and a cross-generational improvement in China.
