Birth order and hand preference in chimpanzees (Pan troglodytes): implications for pathological models of handedness in humans

The effect of birth order on hand preference was assessed in a sample of 154 captive-born chimpanzees. Subjects were classified as first, middle, or latter born using 2 classification criteria based on their birth order. Hand preference was measured using a task that elicited coordinated bimanual actions. Significant birth-order effects were found for both classification criteria, with first- and latter-born subjects exhibiting a lesser degree of right-handedness compared with middle-born subjects. These data suggest that biological rather than sociological factors play a greater role in explaining the observed birth-order effects on hand preference in humans.     

信息载体对初一学生认知负荷与态度偏好的影响

使用认知负荷量表和态度偏好问卷,以相同文章为材料,探究初一学生基于不同信息载体(纸质、电脑、电子阅读器)的认知负荷和态度偏好的差异。结果显示:(1)纸质阅读组的认知负荷大于电脑组和电子阅读器组;(2)电脑组和电子阅读器组的认知负荷和态度偏好均不存在显著差异;(3)被试基于特定载体的认知负荷和态度偏好呈现显著的负相关。所有结果均表明:初一年级的学生更加喜欢进行电子阅读。因此,在现实教学中不必只使用纸质材料,还可适当使用电子阅读。     

听障大学生汉语阅读中的绕口令效应：口语经验和阅读能力的影响

听障者阅读时是否激活语音信息是听障者阅读研究领域的热点问题之一。本研究使用眼动技术,采用绕口令材料,考察口语经验和阅读能力对听障大学生汉语阅读中语音激活的影响。结果发现,口语经验较多且阅读能力较高(OHRH)的听障大学生的绕口令效应大于口语经验较少但阅读能力较高(OLRH)的听障大学生,OLRH组的绕口令效应大于口语经验较少且阅读能力较低(OLRL)的听障大学生。局部指标分析发现OHRH和OLRH组在早期和晚期指标上均存在绕口令效应,OLRL组只在晚期指标上才出现绕口令效应。结果表明,口语经验和阅读能力影响听障大学生汉语阅读中的语音激活。     

Measuring epistemic authority: studies of politicians and professors

Two studies assessed the perception of epistemic authority (denoting a source of information which has a determinative influence on the acquisition of knowledge) by means of a scale (Epistemic Authority Scale) which was constructed for this purpose. The first study showed that individuals perceive political leaders with similar political orientations as greater epistemic authorities than political leaders with different political orientations. In addition, the study investigated the reasons used by the subjects to explain reliance or lack of reliance on political leaders. In general, the responses showed that leaders' expressed opinions and characteristics were important determinants in epistemic authority selection. The second study found that students of statistics departments have a greater tendency to perceive their professors as epistemic authorities in their disciplinary knowledge than students of psychology departments, while the latter are more likely than the former to perceive their professors as epistemic authorities in general knowledge domains. Analysis of the Reason scores for reliance on the professors in the two departments reveals that expertness received the highest ratings.     

Relationships of ordinal position and family size to psychosocial measures of delinquents

First-born, middle-born, and last-born white male delinquents in small and large families (N=72) were compared on 21 variables. Seven of the 21 variables showed some effect of either ordinal position, family size, or their interaction: reading achievement, Quay's unsocialized-psychopathic behavior classification, staff predictions of institutional adjustment, family intactness, Gough's socialization scale, future-events test never responses, and Rosenberg's self esteem scale. The pattern of results suggested that firstborns and delinquents from smaller families were better socialized or had better socialization resources than lastborns and those from larger families.This study was part of a larger research project performed under personal-service contracts CT 24867 and CT 46381 with the Department of Child Welfare, Commonwealth of Kentucky, through Grant No. 73A804 from the Kentucky State Crime Commission with funds made available by the State of Kentucky and the Law Enforcement Assistance Administration, U.S. Department of Justice, under the authority of the Omnibus Crime Control and Safe Streets Act of 1968, as amended.

The effect of negative feedback about oneself and cost of information on preferences for information about the source of this feedback

The present paper reports an experiment in which different amounts of negative self-discrepant information were induced and its effects on information seeking were tested. In addition, the monetary cost of the information available was manipulated. Subjects received fictitious intelligence test results that were negatively discrepant from their self-evaluation. They were then given the opportunity to choose among several articles containing information that either derogated intelligence tests (test-disparaging information) or argued for their validity (test-supporting information). The relative preference for test-disparaging over test-supporting information increased with feedback discrepancy up to a point, but then decreased as this discrepancy became more extreme. The relative preference in reading desirability for test-disparaging over test-supporting articles was also higher when the information cost money than when it did not. In addition, the difference between the desire for the two types of information was greater under cost than under no cost conditions, particularly at the extreme levels of feedback discrepancy.     

The Comparative Effects of a Modified Self-Questioning Strategy and Story Mapping on the Reading Comprehension of Elementary Students with Learning Disabilities

An alternating treatments design was used to examine the effects of story mapping, a modified self-questioning strategy, and no intervention on literal and inferential reading comprehension of elementary students with learning disabilities. Immediate post-tests indicated that students attained significantly greater comprehension in the self-questioning and story mapping conditions over no intervention. Although students attained similarly high levels of overall comprehension when they used story mapping and self-questioning, students scored slightly higher on inferential comprehension questions in the self-questioning condition. Additionally, 4 out of the 5 students indicated a preference for the self-questioning strategy.     

Fundamental factors of comprehension in reading

A survey of the literature was made to determine the skills involved in reading comprehension that are deemed most important by authorities. Multiple-choice test items were constructed to measure each of nine skills thus identified as basic. The intercorrelations of the nine skill scores were factored, each skill being weighted in the initial matrix roughly in proportion to its importance in reading comprehension, as judged by authorities. The principal components were rather readily interpretable in terms of the initial variables. Individual scores in components I and II are sufficiently reliable to warrant their use for practical purposes, and useful measures of other components could be provided by constructing the required number of additional items. The results also indicate need for workbooks to aid in improving students' use of basic reading skills. The study provides more detailed information regarding the skills measured by theCooperative Reading Comprehension Tests than has heretofore been provided regarding the skills actually measured by any other widely used reading test. Statistical techniques for estimating the reliability coefficients of individual scores in principal-axes components, for determining whether component variances are greater than would be yielded by chance, and for calculating the significance of the differences between successive component variances are illustrated.On leave for military service.     

Text Genre and Science Content: Ease of Reading,Comprehension, and Reader Preference

This study examined ease of reading, comprehension, and recall and preference for the same scientific content under two conditions: an informational text and a fictional narrative text. Seventy-four third and fourth graders were assessed individually around the reading of fictional narrative and informational texts that were about either snails or sand. Students’ accuracy and rate of reading were comparable across the two genres. However, students answered more comprehension questions correctly and recalled more key concepts in response to informational text than fictional narrative text. Moreover, students did not express a clear preference for one type of text over the other.     

Teacher reactions to school-based consultation services: A multivariate analysis

The impact of consultation services on teachers' preferences for consultation versus referral approaches and upon teachers' perceptions of severity for common acting out, withdrawal, and academic types of student problems were investigated. The subjects were 96 teachers whose public and parochial schools were matched and randomly assigned to treatment and control groups. Following a 14-week period during which advanced school psychology graduate students served as consultants in the treatment schools, the Pupil Problem Behavior Inventory (PPBI) was administered to all teachers. The results of a repeated measures MANOVA analysis indicated that the teachers in the treatment group rated the acting out and academic problems on the PPBI as significantly less severe than did teachers in the control group. The subjects in both the treatment and control groups indicated a significant preference for consultation rather than referral services for all types of student problems presented in the PPBI. There was a moderate, positive correlation between perceived problem severity and teacher preference for referral rather than consultation services. The study's results were interpreted as supportive of the consultation model.     

Differential effects of oral reading to improve comprehension with severe learning disabled and educable mentally handicapped students

The purpose of this study was to evaluate the effectiveness of oral reading as a teaching technique for improving reading comprehension of 11 Educable Mentally Handicapped or Severe Learning Disabled adolescents. Students were tested on their ability to answer comprehension questions from a short factual article. Comprehension improved following the oral reading for students with a reading grade equivalent of less than 5.5 (measured from the Wide Range Achievement Test) but not for those students having a grade equivalent of greater than 5.5. This association was statistically significant (p = less than .01). Oral reading appeared to improve comprehension among the poorer readers but not for readers with moderately high ability.     

语境线索在留学生阅读伴随词汇学习中的作用：来自眼动的证据

为探讨语境线索在留学生伴随性词汇学习中的作用,本研究选择不同汉语水平的外国留学生作为被试,操纵了语境线索的强弱,使用眼动仪记录被试的词汇学习过程。结果发现：被试在强语境线索下的词汇学习效果显著高于弱语境线索;随着学习次数的增加,强语境线索下目标词注视时间的下降幅度显著大于弱语境线索,高汉语水平被试目标词注视时间的下降幅度显著大于低汉语水平被试。结果表明：无论留学生汉语水平如何,语境线索促进了他们阅读时的伴随性词汇学习,且学习次数越多,语境线索的促进作用越大。     

不同年级学生自然阅读过程信息加工活动特点研究

探讨不同年级学生自然阅读过程的信息加工活动特点,包括两个实验。实验１结果表明,低年级学生自然阅读后再复述文章时需要重读原文的时间比高年级学生要多,据此初步推知,低年级学生自然阅读过程可能主要是单一的语言解码信息加工活动,高年级学生自然阅读过程可能同时进行了语言解码与组织连贯的信息加工活动,以后者为主。实验２比较不同年级的学生在自然阅读、理解任务阅读与记忆任务阅读三种情况下对文章信息保持的效果,结果     

文章标记对阅读理解困难学生信息保持的促进研究

根据阅读理解困难学生不能合理分配注意资源的特点,设置了文章标记这一能引导注意分配的外在线索,并以高层次的主题信息回忆和低层次的从属信息回忆为指标,考察阅读理解正常与困难学生接受标记影响的不同特点。结果表明:(1)文章标记对于阅读理解正常和困难学生的主题信息的回忆均有显著的促进效果,而对于阅读理解困难者的促进作用更为明显。(2)文章标记只促进了阅读理解困难者的从属信息的回忆,对于阅读正常者来说,文章标记反而有损于对从属信息的回忆。     

Preference for news as a function of familiarity

The study was designed to test the hypothesis that interest in information reaches a maximum when something novel is predicted about a well-known subject. The hypothesis predicts that news will be considered more attractive the more familiar its source or theme. This was confirmed in two experiments, where Norwegian and British students were asked to state their interest in reading news from thirty countries of varying familiarity (Experiment 1) or from correspondents in twenty-six capital cities (Experiment 2). Subjects also stated their preferences for reading general information about the same countries or cities, and indicated from which of these they would prefer to receive postcard greetings. The results show preference for news to be closely related to familiarity of country or city ( r =0.93 and r =0.91). General information and postcard preferences were as predicted, less directly related to familiarity.     

风险偏好、信息完整性对职业决策信息加工的影响

本研究旨在探讨个体风险偏好如何影响信息加工过程;同时呈现信息的完整性是否影响个体信息加工过程。以31名正在求职的大学生为被试,探讨了他们在信息板上进行职业决策的信息加工过程。结果显示：(1) 低风险偏好者比高风险偏好者更关注与概率相关的线索;(2) 当信息不完整时,个体在决策中增加了对概率相关线索的关注;(3) 信息完整性对个体决策信息加工过程并未产生显著的影响。     

小学生阅读迁移机制的初步研究--字词表征还是内容表征

探讨文章字词与内容在小学生篇章阅读迁移中的作用。结果发现,阅读水平和阅读条件均对阅读迁移效果有显著主效应。阅读水平低的被试的阅读准确性提高得更大;完全重复条件和词汇重复条件在阅读时间和准确性上都没有显著差异,完全重复条件下的阅读时间和准确性均比意义重复及无相关条件的阅读时间和准确性提高得更多;词汇重复条件下的阅读时间和准确性显著高于意义重复条件下的成绩;词汇相同的阅读准确性也显著高于无相关条件下的阅读准确性。据此,我们可以初步得出小学生的篇章阅读迁移主要依赖词汇表征,即词汇表征是小学生篇章阅读迁移的主要机制。

Sport injuries: relations to sex, sport, injured body region

Relationships among hand preference, nonverbal intelligence, and the monocular shifts of binocular focal point were studied in 33 men and 12 women university mathematics students. Ocular dominance was assessed with the Miles test. The monocular shift of binocular focal point for each eye was assessed with a modified Miles test. Hand preference was assessed on the Edinburg Handedness Inventory. Nonverbal intelligence was assessed with Cattell's Culture Fair Intelligence Test. In a prior study, the percentage of left-eye preference had been reported to be greater for mathematics students than for nonmathematics students. In the present study there were positive correlations between hand preference and the sum of the monocular shifts of two eyes. In addition, there was a negative correlation between nonverbal intelligence and the sum of the monocular shifts of two eyes. As these resultssuggest that the sum of the monocular shifts of two eyes may be related to mathematical ability and nonverbal intelligence, further research with a larger sample including non-mathematics students is needed.
