The early resumption of employment by mothers: Implications for parent-infant interaction

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers.     

相信智力不变是否也认为个性难改?——个人属性内隐观的普遍性

动机理论的认知心理学派认为 ,学生对智力、个性等个人属性 ,是否先天固有不可改变的主观想法 ,将直接影响他们的学习和行为表现。其影响的范围 ,将取决于这类主观想法是否具有普遍性。比如 ,有些学生认为智力是父母遗传的 ,很难改变 ,这些学生会否同样认为个性、道德等 ,也是父母遗传 ,亦难改变 ?该研究希望了解是否有一主导思想 ,影响学生对智力、个性等不同个人属性 ,是否先天不变的整体看法。被试为中国长春市高中一年级的学生 ,总计 5 5 5人。研究采用问卷调查 ,通过比较多个结构方程模型 ,结果较倾向支持学生对个性、智力等五项个人属性有共通一致的内隐观     

汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响

本研究探讨了汉字词在不同方位与不同排列组合条件下对念读速度与准确性的影响.实验结果表明逆意排列的汉字词处于不同方位(正位、左右倾斜90°、倒位),对汉字词的念读速度产生明显影响.汉字词处于正位时,念读速度最快;其次是处于左斜与右斜90°;对汉字词的念读速度最慢而准确性最低是处于倒位时(汉字词颠倒).汉字词无论是顺意排列或是逆意排列,正位结果均明显优于倒位结果;但汉字词在倒位顺意排列条件下,结果优于正位逆意排列的结果,这表明,字词间的意义联系的作用大于字词方位的作用.     

Hemispheric patterns in visual search

A visual search paradigm was employed to examine hemispheric serial and parallel processing. Stimulus arrays containing 4, 9, or 16 elements were tachistoscopically presented to the right visual field-left hemisphere (RVF-LH) or left visual field-right hemisphere (LVF-RH). Subjects judged whether all of the elements within an array were physically the same (all X's) or whether one (O) was different from the rest. Left hemisphere presentations were processed more quickly and accurately than LVF-RH presentations for all stimulus conditions. As the number of array elements increased, more errors and longer response times were obtained for different stimulus items whereas fewer errors and somewhat shorter response times were obtained for same stimulus items. These and previous results suggest that the left hemisphere obtains an advantage for visual search because of that hemisphere's superiority for fine-grained feature analysis rather than because of a fundamental hemispheric serial/parallel processing dichotomy.     

对“物体内注意转移”优势效应之机制的进一步检验

针对“选择性注意基于空间还是基于物体”的问题,从Ｅｇｌｙ等与Ｖｅｃｅｒａ等的争论出发,考察“物体内注意转移”的优势效应是否与空间因素有关,首先,与以往研究结果一致,观察到：与提示无效时相比,空间提示有效时被试对目标的反应较快,这提示基于空间的注意成分的存在;通过改变两个背景物体的形状和颜色,减弱两者之间的知觉组织之后,还发现“物体内注意转移”的优势效应与空莘距离无关,后一结果为基于物体的选择性注意     

Birth Order and Civil Disobedience: A Test of Sulloway's “Born to Rebel” Hypothesis

Abstract

In Born to Rebel, F. Sulloway (1996) argued that, throughout history, laterborns have been more likely than first-borns to challenge the status quo. The authors tested Sulloway's hypothesis among a group of U.S. college students who had participated in civil disobedience as part of a labor dispute. The authors predicted that there would be a higher percentage of later-borns among those who had been arrested than among a group of their friends who had not participated in civil disobedience or among a control group of students drawn from classes at the college. The findings, in fact, revealed a significant relationship between the number of times the students had been arrested and birth order.
