Multi-Encoding for Pitch Information of Tone Sequences

This study was designed to investigate the possibilities that subjects would visualize an auditory contour as a visual contour (visual imagery) to encode pitch information of tone sequences (Experiment 1), and that subjects would be motivated to attempt to engage in covert rehearsal with multi-code (Experiment 2). The findings from these experiments suggest that: (a) Whereas the highly musically trained subjects were able to encode pitches as accurate notes on a staff, the less well musically trained subjects encoded the pitch sequence as a contour. It is quite evident that there is an intermodal analogy between the perception of pitch relationships and that of relationships in visual space. (b) Pitch rehearsal of auditory information along with note names (dual-code) and staff notation accompanied by pitch rehearsal with note names (triple-code) were the most effective strategies for highly trained subjects with pitches of tonal sequences; melodic contour accompanied by pitch rehearsal (dual-code) was used by highly trained subjects with atonal sequences and by less well trained subjects with both types of sequences.     

Auditory discrimination: role of time and intensity in the precedence effect.

Rats were trained to respond on a lever adjacent to a sounding speaker (the sound source) when a single click was emitted. A second click (the artificial echo) was presented through a second speaker on the opposite side. In Condition I, the echo (equal in intensity to the source) was delayed from .015 to 32 milliseconds; greater than 75% correct responses were given for delay times between about .040 milliseconds (lower threshold) and 8 milliseconds (upper threshold). In Condition II, the echo (simultaneous with the source) was reduced in intensity relative to the source over a range from 2.5 decibels to 40 decibels; greater than 75% correct responses occurred for intensity reductions greater than 5 decibels. In Condition III, both the intensity and the delay time of the echo were manipulated in a manner analogous to that which would occur under natural conditions; greater than 95% correct responses were given for delay times from 1 to 32 milliseconds. These data indicate that both time and intensity differences are necessary for localization of primary sources, with delay time contributing more at short echo path distances, and intensity differences at long distances.     

听觉、时间加工能力与发展性阅读障碍

近年来阅读障碍者的知觉加工越来越受到重视 ,本文介绍了近期国外关于阅读障碍者的听觉加工能力、时间加工能力的最新研究进展。快速听觉加工能力的缺失在阅读障碍者身上普遍存在 ,并被认为是阅读障碍产生的主要原因 ;有研究者提出“时间控制障碍”假说 ,认为阅读障碍源自一种普遍性的时间知觉障碍 ,不具有通道特异性。除此之外 ,还发现阅读障碍者对声音频率、响度等非时间特征也出现了觉察困难。通过这些研究我们可以看到 ,听觉加工能力、快速时间加工能力与阅读能力之间可能有着密切的关系 ,但这几种能力如何具体作用于阅读发展 ,它们之间如何相互作用、相互影响仍需进一步探讨。

提出两种认知诊断计算机自适应测验下平衡属性收敛的新方法（MABI、RTA）,模拟研究系统探讨和比较了此二者与已有方法（ABI、IABI和RABI）的表现。结果发现：（1）新方法较不考虑属性收敛的方法有更高的准确率以及更均衡的题目使用率;（2）新方法较ABI和RABI有稍低的准确性,但有更平衡的题目使用率;（3）新方法与IABI的准确性和题目使用率在不同选题策略下各有合优势。总之,两种新方法较好地兼顾测量准确性、题目使用率以及题库曝光情况。     

中国的心理测量发展史

有关心理测量的思想起源于中国古代。但西方科学的心理测验理论与方法是20世纪初自西方传人中国的。30年的发展取得很大成绩,但道路艰辛曲折,文章分三个阶段对之作了回顾。一、最早是1915年外国学者为比较中美儿童的智力差异对广州500名小学生进行测试。同一时期,我国学者也开始自己编制测验,"小学生毛笔书法量表"是最早的标准化教育测验。廖世承和陈鹤琴1920年在南京高等师范开设测验课程,出版《心理测验法》一书,正式介绍科学的心理测验。与美国专家合作编制多种测验,1923年与美国专家合作对全国小学生进行测试,得出了三至八年级学童的年龄与班级常模,引起了教育界的注意。艾伟从1925年起致力编制中小学不同年级和学科的测验以及能力测验,还与张耀翔编制了识字测验与阅读测验等,对我国教育测验的发展做出了很大贡献。"中国测验学会"1931成立。并创办会刊《测验》有效地推动了当时测验研究的开展.1937年"七七"事变后,工作继续进行和扩展,但受战争的影响,发展上减慢了速度。二、1949年新中国成立后,由于政治上的变迁,心理测验被视为禁区,认为它违心,反动,没有人敢于问津。文化大革命中,心理学被打成伪科学,心理测验更是全盘否定了。三.文革以后,心理学恢复。而心理测验面对着既缺人力又少资料的困难。林传鼎等三位教授于1980年春举办了第一个全国性心理测验培训班,是心理测验再生的标志。此后各高等院校逐步开设心理测量学课程。通过引进各种心理测量理论,修订外国测验和逐步向自编我国测验发展,几年中取得了良好效果。1984年中国心理学会下属的‘心理测量分会’成立,1990年加入国际测验委员会(ITC)成为它的一个国家会员。1991年在南京举办了国内第一个心理测验国际性学术会议,又与台湾学者交流,建立起隔年一次海峡两岸心理与教育测量学术研讨会的协议。这些都对中国心理测验的发展都起了积极作用。80年代后期国家实行改革开放,经济转型,心理测验逐渐渗入医学、教育、企业、和组织人事部门等多种应用领域,扩大了对社会的影响。教育是其最早也是最重要的应用领域。从高考开始向各种考试、应用领域广泛扩展,取得良好效果。尤其是在人力资源、心理咨询领域,心理测验发展迅速日益兴旺。社会各界从多方面加深了对心理测量的认同,使它变成为一个相当热门的应用科学了。最后,文章从测验的数量、质量,数据处理的方法技术,测验者素质提高和法律完备等几个方面分析了存在问题并提出对今后的展望。     

同音字族内的听觉通道词频效应与同音字表征的激活

对于同音词家族较大的词汇(例如汉语单音节词), 听觉通道的词汇通达和词汇表征的激活会受同音词汇歧义怎样的影响, 仍不很清楚。本研究采用了两个听觉通道的实验。实验一的听写任务发现在孤立音节的同音字选择上存在歧义的同时还存在同音字族内的高频偏向, 并非随机选择; 实验二的音-字同音判断任务对比同音与不同音条件得到同音促进量, 揭示了孤立音节在激活语音表征时还会引起同音高频字表征的自动激活, 而同音低频字则受到抑制。结果说明存在同音字族内的听觉通道词频效应, 同音的高、中、低频字的表征激活具有不同等性, 导致不穷尽通达, 且同音的最高频字得到更多通达机会。这些发现难以被现有的词汇通达和同音词表征激活模型解释, 文章提出一个能够解释这些听觉通道发现的模型。     

Individual differences in category learning: sometimes less working memory capacity is better than more

We examined whether individual differences in working memory influence the facility with which individuals learn new categories. Participants learned two different types of category structures: rule-based and information-integration. Successful learning of the former category structure is thought to be based on explicit hypothesis testing that relies heavily on working memory. Successful learning of the latter category structure is believed to be driven by procedural learning processes that operate largely outside of conscious control. Consistent with a widespread literature touting the positive benefits of working memory and attentional control, the higher one’s working memory, the fewer trials one took to learn rule-based categories. The opposite occurred for information-integration categories - the lower one’s working memory, the fewer trials one took to learn this category structure. Thus, the positive relation commonly seen between individual differences in working memory and performance can not only be absent, but reversed. As such, a comprehensive understanding of skill learning - and category learning in particular - requires considering the demands of the tasks being performed and the cognitive abilities of the performer.     

Speech Perception Within an Auditory Cognitive Science Framework

ABSTRACT— The complexities of the acoustic speech signal pose many significant challenges for listeners. Although perceiving speech begins with auditory processing, investigation of speech perception has progressed mostly independently of study of the auditory system. Nevertheless, a growing body of evidence demonstrates that cross-fertilization between the two areas of research can be productive. We briefly describe research bridging the study of general auditory processing and speech perception, showing that the latter is constrained and influenced by operating characteristics of the auditory system and that our understanding of the processes involved in speech perception is enhanced by study within a more general framework. The disconnect between the two areas of research has stunted the development of a truly interdisciplinary science, but there is an opportunity for great strides in understanding with the development of an integrated field of auditory cognitive science.     

计算机人格适应性测验的初始值估计研究

一般来说,对于计算机人格适应性测验（CAPT）,由于对被试每种人格特质的施测项目数比较少,初始值估计方法的好坏直接影响着被试人格特质水平估计的准确性。该研究提出利用被试特质水平与其人格特质自我评定信息的回归模型来获取被试人格特质水平的初始值。模拟数据的研究结果表明：新方法获得的初始值确实能够更准确的估计被试的特质水平。     

A Review of the Stereotype Threat Literature and Its Application in a Neurological Population

Stereotype threat is a situational phenomenon, leading to test performance decrements, in which a member of a stigmatized group feels pressured by the possibility of confirming or being judged by a negative stereotype. This review article highlights the progression of research in the stereotype threat field, and its relevance to neurological populations. Early studies focused on demonstrating this effect in African American, women, and elderly populations. Since this time, research has continued to focus on these populations but has moved to elucidating stereotype threat's mediating psychological factors, studying the impact of individual differences in response to stereotype threat, and attempting to reduce its overall effect. A proposal for further study in neurological populations, under the framework of stereotype threat, comprises the last portion of the paper. It is argued that this social psychological phenomenon may, at least in part, account for poor neuropsychological test performance for neurologically compromised individuals.
