Sensory conflict in judgments of spatial direction

Artificial discrepancy was created between information about azimuth coming from different sense modalities. The resolution of this discrepancy was examined for the cases of vision and proprioception, proprioception and audition, and vision and audition. Vision biases proprioceptive and auditory judgments. Proprioception biases auditory judgments and has a small effect on visual judgments. The results suggest that the combinations of sense modalities do not behave as an integrated system and the data are interpreted as indicating that different processes are involved in the resolution of discrepant directional information from different pairs of modalities.     

Do birds of a feather flock together? A test of the similarities within and the differences between five occupations

Two sets of samples of 40 women from each of five different occupations were subjected to J. H. Ward's (Journal of the American Statistical Association, 1963, 58, 236–244) hierarchical cluster analysis, using an index of similarity from Kuder, 1977, Kuder, 1980, 40, 1–8). The five-group solution in neither case adequately recaptured the occupational membership of the original groups. This finding was interpreted to mean that there may be important differences in the interests of person in the same occupation, which in turn has implications for occupational scaling on interest inventories and theories of career development and counseling.     

Gender differences in anger and fear as a function of situational context

Gender differences in the reported intensity of anger and fear toward hypothetical males and females were explored in three age groups (6–12 year olds, 14–16 year olds, and adults over 30) located in two different geographic areas. The samples were primarily Caucasian and included a wide range of socioeconomic groups. Subjects reported on the intensity of feelings elicited by characters in an emotion story task in which three aspects of situational context were varied: the gender of the story characters eliciting the feeling (all situations), the stereotypic gender-typed or cross-gender behavior of the eliciting character (four situations), and the affective quality of the situations (four situations). Across all three age groups, situations that were frightening, anger-provoking, or that depicted stereotypic male-negative behavior elicited the most consistent subject gender and character gender differences in reported fear and anger. Relative to males, females of all ages reported more fear in frightening, anger-producing, and male-negative stereotypic situations. Males were reported to be more frightening and anger-producing than were females in those same situations. The data also suggested that with development, females reported less intense fear of females, while males reported less intense fear of males.This research was supported by a Gender Roles grant from the Rockefeller Foundation. We appreciate their support. We would also like to thank the public school systems of Milton, Norwood, and Watertown, Massachusetts, and Saskatoon, Saskatchewan, Canada. Finally, we would like to thank Lance Davidow, John Houlihan, and Theodore Cross for statistical consultation and/or computer programming, as well as all the parents, children, and adolescents who participated in the study.     

Resolving power of the perceptual- and sensorimotor systems in 6- to 10-year-old children

Children aged 6 to 10 were tested on their ability to move accurately and to perceptually evaluate their motor response. Subjects performed a directional and an amplitude visuo-manual aiming task without vision of their moving limb. They were asked to correct their error, after completion of their movements, only if they felt they were not accurate. Terminal aiming errors and correction responses (adjustments) were analyzed, and threshold detection was determined relative to terminal aiming error. Action accuracy and evaluation of action accuracy are two abilities that do not develop synchronously. Moreover, the relationship between these abilities depends on whether accuracy and direction or amplitude are required. Amplitude undergoes more corrections than direction, suggesting that the spatial system of reference involved depends more upon the coding of the final position than on direction. Two spatial comparators, operating on the basis of two types of evaluation, seem to have a variably distinct contribution to movement and perception accuracy, according to age.     

分离遗传与环境对儿童发展的影响：介绍一个新颖的研究方法

本文介绍一个可以用于研究遗传与环境互动的新颖方法。此研究收集了上千个4~10岁儿童的数据。这些儿童的出生都借助于不同的辅助受孕技术（Assisted Reproductive Technologies）,包括试管婴儿、精子捐赠、卵子捐赠、胚胎捐赠及代孕技术。本项目通过妇科（助孕）医院收集被试的行为数据,包括家庭互动、养育方式、父母婚姻质量、家庭成员的心理健康及经济状况等。本文选择性地介绍一些分析的结果,以彰显这种设计在分离遗传和产前产后环境对儿童发展的贡献。首先,我们比较了“助孕”儿童与“自然孕”儿童在父母冲突、父母对子女敌意以及儿童抑郁症状之间关系的异同。其次,我们比较了这两组儿童在父母抑郁症状、家庭关系质量以及儿童抑郁症状之间关系的异同。再次,本文介绍了这一可分离遗传与环境因素的研究设计。最后,我们讨论了这一设计对发展心理病干预及预防的意义     

Spirituality versus Individualism: Why we should nurture relational consciousness

This paper proposes an approach to spiritual education which transcends the religious-secular boundary by conceiving of spirituality as a natural human predisposition labelled 'relational consciousness'. Evidence drawn from recent research demonstrates that this predisposition is universally identifiable in young children and expresses itself in many forms apart from the religious. Nevertheless it is this which allows the possibility of religious belief. As a result of the cultural construction of an extreme individualism which is particularly evident in the Western world, there has been a 'forgetting' of relational consciousness/spirituality resulting in damaging effects to the texture of human community. Some major sources of individualism are identified as having particularly serious effects on relational consciousness. These are reflected upon in the light of empirical research on children as well as contemporary philosophical and political critiques. Spiritual education is seen as a major means of resistance to the damaging effects of possessive individualism.     

The roots and branches of human altruism

The authors' rigorous and ingenious programme of work documents young humans' capacity for prosocial action ( Warneken & Tomasello, 2009 ). Their laboratory findings are corroborated by centuries of observational data, spanning cultures, and historical epochs. Two general questions are raised. Firstly, what are the rules of evidence needed in using comparative data to make claims about the evolution of human social behaviours? Secondly, what ontogenetic processes contribute to the transformation of toddlers' helpfulness into mature, cognitively informed and rule‐governed altruism? These findings alone do not provide complete evidence for the phylogenetic roots of altruism. I argue that selective pressures in human evolution have favoured sociability, which could lead to aggression or altruism, depending on context and the nature of the rearing environment. Any social behaviour shown in infancy may have multiple functions, at phylogenetic, ontogenetic and episodic levels of analysis.     

Perception of rhythmic grouping: testing the iambic/trochaic law

This study was designed to test the iambic/trochaic law, which claims that elements contrasting in duration naturally form rhythmic groupings with final prominence, whereas elements contrasting in intensity form groupings with initial prominence. It was also designed to evaluate whether the iambic/trochaic law describes general auditory biases, or whether rhythmic grouping is speech or language specific. In two experiments, listeners were presented with sequences of alternating /ga/ syllables or square wave segments that varied in either duration or intensity and were asked to indicate whether they heard a trochaic (i.e., strong-weak) or an iambic (i.e., weak-strong) rhythmic pattern. Experiment 1 provided a validation of the iambic/trochaic law in English-speaking listeners; for both speech and nonspeech stimuli, variations in duration resulted in iambic grouping, whereas variations in intensity resulted in trochaic grouping. In Experiment 2, no significant differences were found between the rhythmic-grouping performances of English- and French-speaking listeners. The speech/ nonspeech and cross-language parallels suggest that the perception of linguistic rhythm relies largely on general auditory mechanisms. The applicability of the iambic/trochaic law to speech segmentation is discussed.
