研究生归因风格及其与自尊关系的研究

研究采用多维归因量表(MMCS)和自尊量表(SES)对研究生归因风格及自尊对归因风格的影响进行调查研究,结果显示:总体上,研究生归因风格呈现内控倾向,年级之间差异显著;对于成败,高自尊学生倾向于归因努力、能力等内部因素;自尊对归因风格有较好的预测作用。     

不同归因方式的诱导对自尊不同学生失败后测验成绩的影响

采用2×2两因素被试间设计检验了不同归因方式的诱导对自尊不同学生失败后测验成绩的影响。结果表明:(1)总体上,高自尊组在失败后的测验成绩显著优于低自尊组;(2)内部归因后,高自尊组的后继测验成绩非常显著地优于低自尊组;外部归因后,高、低自尊组的后继测验成绩无显著差异;(3)对于高自尊组,内部归因后的后继测验成绩优于外部归因后的成绩,但未达到显著性水平;对于低自尊组,外部归因后的成绩显著优于内部归因后的成绩。     

当前儿童交往归因研究的特点

交往归因是影响儿童交往的重要认知因素。近来．随着认知研究的深入．交往归因日趋成为交往机制研究的重要课题。从已有资料看来,儿童交往归因研究具有如下几个特点：多元视角研究的进行;研究方法力求科学化;改善交往归因不良状况的归因训练开始受到重视等。     

汉语词类歧义解决(Ⅱ)

采用眼动记录阅读范式,考察汉语词类歧义解决过程。阅读材料为含有单字词类歧义词的句子,歧义词前面的语境不提供明确的偏向性信息,后语境提供解歧信息。结果发现,当后语境支持次要用法时,歧义词及后面第一个解歧区的总阅读时间加长,歧义词后第二个解歧区的回扫次数增多,而当后语境支持主要用法时没有出现类似的现象,表明相对频率能够即时影响词类歧义解决过程,结果支持基于制约的模型。文章对汉语词类歧义解决过程、不同实验技术及其引起的差异进行了讨论。     

The discounting of ambiguous information in economic decision making

In three experimental studies we investigated how decision makers respond to ambiguous information about costs and benefits. In Experiment 1, we studied the effect of ambiguity about prior costs. Experiments 2 and 3 focused on the effect of ambiguity about future outcomes. The collective results of the three studies suggest that decision makers discount ambiguous information. The findings are related to insights on the disjunction effect, the sunk cost effect, transaction decoupling, and ambiguity aversion. Copyright © 2003 John Wiley & Sons, Ltd.     

Sleep problems,anxiety and cognitive style in school‐aged children

The associations between sleep problems, anxiety, anxiety sensitivity and attributional style were examined in self‐report data from 79 children aged 8–11 years. Total anxiety score was associated with different types of sleep problems (bedtime resistance, sleep anxiety and nightmares). Conversely, total sleep problem score was associated with different sub‐scales of anxiety (from r(78) = 0.15, p = NS to r(79) = 0.47, p < 0.01). Symptoms of anxiety correlated significantly with anxiety sensitivity, but not with attributional style. After controlling for other symptoms of anxiety, school phobias (Beta = 0.26, p < 0.05), the mental incapacitation concerns scale of anxiety sensitivity (Beta = 0.26, p < 0.05), and attributional style (Beta = −0.31, p < 0.01, R² = 0.45) predicted sleep problems. These results suggest that anxiety is associated with a range of sleep problems, and that sleep problems are associated with different types of anxiety. Furthermore, certain cognitive styles are associated with both anxiety and sleep problems and may be good candidates for further research into the association between sleep problems and anxiety in children.

Modelling the effects of semantic ambiguity in word recognition

Most words in English are ambiguous between different interpretations; words can mean different things in different contexts. We investigate the implications of different types of semantic ambiguity for connectionist models of word recognition. We present a model in which there is competition to activate distributed semantic representations. The model performs well on the task of retrieving the different meanings of ambiguous words, and is able to simulate data reported by Rodd, Gaskell, and Marslen-Wilson [J. Mem. Lang. 46 (2002) 245] on how semantic ambiguity affects lexical decision performance. In particular, the network shows a disadvantage for words with multiple unrelated meanings (e.g., bark) that coexists with a benefit for words with multiple related word senses (e.g., twist). The ambiguity disadvantage arises because of interference between the different meanings, while the sense benefit arises because of differences in the structure of the attractor basins formed during learning. Words with few senses develop deep, narrow attractor basins, while words with many senses develop shallow, broad basins. We conclude that the mental representations of word meanings can be modelled as stable states within a high-dimensional semantic space, and that variations in the meanings of words shape the landscape of this space.     

The logic in language: How all quantifiers are alike,but each quantifier is different

Quantifier words like each, every, all and three are among the most abstract words in language. Unlike nouns, verbs and adjectives, the meanings of quantifiers are not related to a referent out in the world. Rather, quantifiers specify what relationships hold between the sets of entities, events and properties denoted by other words. When two quantifiers are in the same clause, they create a systematic ambiguity. “Every kid climbed a tree” could mean that there was only one tree, climbed by all, or many different trees, one per climbing kid. In the present study, participants chose a picture to indicate their preferred reading of different ambiguous sentences – those containing every, as well as the other three quantifiers. In Experiment 1, we found large systematic differences in preference, depending on the quantifier word. In Experiment 2, we then manipulated the choice of a particular reading of one sentence, and tested how this affected participants’ reading preference on a subsequent target sentence. We found a priming effect for all quantifiers, but only when the prime and target sentences contained the same quantifier. For example, all-a sentences prime other all-a sentences, while each-a primes each-a, but sentences with each do not prime sentences with all or vice versa. In Experiment 3, we ask whether the lack of priming across quantifiers could be due to the two sentences sharing one fewer word. We find that changing the verb between the prime and target sentence does not reduce the priming effect. In Experiment 4, we discover one case where there is priming across quantifiers – when one number (e.g. three) is in the prime, and a different one (e.g. four) is in the target. We discuss how these findings relate to linguistic theories of quantifier meaning and what they tell us about the division of labor between conceptual content and combinatorial semantics, as well as the mental representations of quantification and of the abstract logical structure of language.
