项目摘要

The objective of this continuing reaserch is to examine two related questions: (1) the relation between measured intelligence and family size; and (2) the relation between measured intelligence and birth order. The analyses will be based on data from the Wisconsin Longitudinal Study. Our second research paper on the relation between intelligence and family size will focus on the question, "How Intelligence Affects Fertility." The research will include path and other multivariate analyses of how background factors, IQ, and intervening factors affect fertility. The research on the influence of birth order on IQ will be done first in the usual way with between-families data from the full Wisconsin sample. The second and more novel approach will employ within-families data from the Wisconsin sib sample and will use the respondent-sib difference in IQ, indexed by birth orders of respondent and sib, as the dependent variable. This within-family difference automatically controls for many confounding factors, since respondent and sib share the same parents. The second approach therefore promises to give more informative results than the first. The Wisconsin sib sample is well-suited to test the key results than the first. The Wisconsin sib sample is well-suited to test the key prediction of the latest version of the Zajonc-Markus confluence model of how birth order and related family structure variables affect intellectural development. This test of the confluence model, which will also include investigation of sibship size effects, will form a major focus of the continuing research. The research will continue to address questions about population quality deriving from the associations of size of family of origin and sibling position with measured intelligence and the association of measured intelligence with fertility.

这项持续研究的目的是检查两个相关问题：（1）测量智力之间的关系和家庭规模； (2) 测量值之间的关系智力和出生顺序。分析将基于数据来自威斯康星州纵向研究。我们的第二篇关于智力之间关系的研究论文和家庭规模将集中在这个问题上：“智力如何影响生育能力。”该研究将包括路径和其他背景因素、智商和影响因素的多变量分析干预因素影响生育能力。将进行出生顺序对智商影响的研究首先以通常的方式使用完整的家庭间数据威斯康星州样本。第二种更新颖的方法将采用来自威斯康星州同胞样本的家庭内部数据，将使用受访者与同胞的智商差异，按出生索引受访者和同胞的顺序作为因变量。这家庭内部的差异自动控制了许多人混杂因素，因为受访者和同胞有相同的情况父母。因此，第二种方法有望提供更多结果比第一个信息丰富。威斯康星州同胞样本是比第一个更适合测试关键结果。威斯康星号 sib 样本非常适合测试最新的关键预测出生顺序的 Zajonc-Markus 汇合模型的版本以及相关的家庭结构变量影响智力发展。本次测试融合模型，也将包括对同胞规模效应的调查，将形成一个主要的持续研究的重点。该研究将继续解决有关人口的问题品质源于原生家庭规模的关联和兄弟姐妹的位置与测量的智力和关联衡量智力与生育能力的关系。
