澳门人的风险知觉与赌博行为

采用匿名问卷法,调查澳门人的风险知觉与赌博行为。结果显示：（1）赌场的劝世文既无劝勉也无劝阻人们赌博的作用;（2）社会关系网的钱财支援不影响实际赌博次数;（3）多次性博弈与一次性博弈所采用的是不同的机制,一次性博弈不是由期望值所决定的;（4）相互监视和制裁系统会影响赌博：受法律制裁约束的职业者比不受法律制裁约束的职业者更不好赌;自估在赌场遇见认识人的机会与赌博次数呈负相关;（5）性别及母语等“本质趋向”差异表明,所谓澳门人不好赌有其渊源并可能是在长期的文化沉淀中形成的;（6）受教育程度是影响赌博的有效预测变量。这些发现的理论含义一并进行了讨论。     

Lexical activation during the recognition of Chinese characters: Evidence against early phonological activation

In two primed-naming experiments involving Chinese character recognition, one with native Mandarinspeaking subjects and another with native Cantonese-speaking subjects, we varied both the stimulus onset asynchrony (SOA) and the prime—target similarity along various lexical dimensions. Across both experiments, the results were as follows: (1) Relatively strong and reliable semantic priming appeared very early across various SOAs, and its onset was not affected by meaning precision, (2) either homophonic priming had negligible effects on target naming or the effects appeared relatively late (only at 57 msec), and (3) graphic inhibition was found across different SOAs. Since the same set of stimuli and procedure were adopted as those in the study of Perfetti and Tan (1998), the present findings raise questions about the reliability and validity of the results from their study that have been used to support the notion that phonology is a constitutive element of character recognition and precedes meaning access in the identification process. Instead, the present results suggest that phonology is optional for accessing meaning in Chinese character recognition among skilled adult readers.     

职业胜任心理素质测评指标体系研究

本研究采用文献总结法、工作分析法、专家评判法、问卷调查法、五级估量模糊集评判技术等,对公安民警职业胜任心理素质进行分析,从基本心理素质、特殊心理素质两级水平及一般能力、人格特质、社会能力三个维度,构建了八类警种的公安民警职业胜任心理素质评价体系,简称"2级3维"评价体系.本研究结果为制定更为科学实用的公安民警心理素质的测评工具提供依据.     

移动窗口条件下阅读过程中字词识别特点的研究

采用“移动窗口”技术对中文阅读过程中的字词识别进形了初步的探讨。被试是８名大学生,阅读材料为８篇科学文章。结果发现,在移动窗口条件下,词的注视时间受词频、词中字数等词本身特性,词在理解文章中的重要性以及句子界限效应、文章难度等来自阅读理解的高级过程的影响。移动窗口技术可以在一定程度上较真实地探讨阅读中字词的连续加工过程。     

额区脑波年老化特点及其与某些认知能力的相关性

对１２０名中老年被试（４６－８０岁）,完成双额脑波年老化特点０及其与某些认知能力相关性的研究。认知能力测验共１２项作业,包括４项作业速度和１０项作业成绩共１４项指标。结果表明：（１）双额脑波α峰频率随年老低移,α功率随年老有增加趋势;（２）年老过程３项作业速度与双额α峰频率相关性显著,但仅“图象自由回忆”成绩与双额α峰频率及右额α功率相关性显著。     

插图在说明文阅读理解中的作用

研究的目的在于揭示插图对说明文阅读理解的影响。实验中使用移动窗口技术对阅读过程中插图的作用进行探讨,并考察空间想象能力在其中的作用。结果表明：１．插图可以改进说明文的阅读理解,提高阅读速度;２．插图可以帮助读者建立文章所描述物体的参照表征,在建立参照表征的过程中,插图有利于重要概念的理解和有关参照表征信息的整合;３．插图有助于空间想象能力低的读者理解重要概念以及整合有关信息。     

与年龄及认知功能相关的成人脑波功率涨落图特点

对１２０名２０－７９岁正常受试者完成了与年龄及认知功能相关的脑涨落图特点的研究。结果表明：（１）脑波优势涨落功率空间构型额低枕高梯度的随龄减小过程,在认知测验差组较好组明显;（２）脑波优势涨落功率受年龄与认知因素的交互影响集中于左前右后脑轴上;（３）脑波优势涨落功率前后梯度和左右不对称性变化表明,脑波活动的前后和左右调控可能在不同层次上发挥作用,并且,前后脑和左右脑的协调活动与认知功能有密切关系。上述结果说明,脑波功率涨落与认知功能及其老化过程有密切关系。     

Preventing smoking: evaluating the potential effectiveness of cigarette warnings.

We examined the potential effectiveness of U.S. government cigarette warnings in preventing adolescent smoking. In Study 1, 112 seventh graders rated the effectiveness of four currently required warnings and four possible other warnings and answered questions about the meaning of certain words in the warnings. In Study 2, 115 seventh graders attempted to recall the four current warnings; in Study 3, 103 eighth and ninth graders read all eight warnings one day and tried to recall them the next day. In Study 4, 25 seventh graders participated in a focus session in which they discussed the effectiveness of each of the eight warnings. The results of the studies showed that the four different evaluation strategies had convergent validity and that two current warnings and two proposed warnings are significantly more potentially effective than the other two current warnings. Our results also provided information about why some warnings are more potentially effective than others.     

成年熟练读者的汉字读音加工过程

本研究对成年熟练读者的汉字读音过程作了初步探讨。被试为大学生,实验材料以形声字为主,研究方法使用命名潜伏期法。实验一研究了不同字形、不同字频的单个汉字的读音,发现被试读汉字有直接提取、声旁及类似推理三种加工方式。高频字的读音以提取为主;中频字读音时,声旁和类似推理的作用增加;低频字读音时提取基本不起作用。实验二中发现,声旁的发音一致性对低频字的读音影响很大。激活熟悉的类似字,以确定刺激字的读音,是低频字读音的一个重要方式。
