2.	Intelligence, Income, and Education as Potential Influences on a Child's Home Environment: A (Maternal) Sibling-Comparison Design Developmental Psychology 53,7 (July 2017): 1286-1299. Also: http://psycnet.apa.org/journals/dev/53/7/1286.html Cohort(s): Children of the NLSY79, NLSY79 Publisher: American Psychological Association (APA) Keyword(s): Armed Forces Qualifications Test (AFQT); Home Environment; Household Income; Intelligence; Kinship; Mothers; Parental Influences; Siblings The quality of the home environment, as a predictor, is related to health, education, and emotion outcomes. However, factors influencing the quality of the home environment, as an outcome, have been understudied--particularly how children construct their own environments. Further, most previous research on family processes and outcomes has implemented between-family designs, which limit claims of causality. The present study uses kinship data from the National Longitudinal Survey of Youth to construct a maternal sibling-comparison design to investigate how maternal and child traits predict the quality of home environment. Using a standard between-family analysis, we first replicate previous research showing a relationship between maternal intelligence and the quality of the home environment. Then, we reevaluate the link between maternal intelligence and the home environment using differences between maternal sisters on several characteristics to explain differences between home environments for their children. Following, we evaluate whether child intelligence differences are related to home environment differences in the presence of maternal characteristics. Results are compared with those from the between-family analysis. Past causal interpretations are challenged by our findings, and the role of child intelligence in the construction of the home environment emerges as a critical contributor that increases in importance with development.

3.	Intelligence and Fertility in the NLSY79 Respondents: Children of Siblings and Biometrical Models Presented: Charlottesville VA, Behavior Genetics Association (BGA) Annual Meeting, June 2014 Cohort(s): NLSY79 Publisher: Behavior Genetics Association Keyword(s): Age at First Birth; Age at First Intercourse; Armed Forces Qualifications Test (AFQT); Genetics; I.Q.; Intelligence; Kinship; Modeling, Multilevel; Siblings Permission to reprint the abstract has not been received from the publisher. The current study uses the family structure of the original National Longitudinal Survey of Youth (NLSY79) dataset to evaluate several questions related to fertility outcomes. Recent work using both the NLSY79 and the NLSY-Children data has taken advantage of the kinship links in these surveys to control for family history—both genetic and environmental—using a Children of Siblings (COS) design. The NLSY79 females have recently completed childbearing, and the males have virtually completed childbearing (respondents were age 47–55 in the most recently released 2012 survey). We use a COS design in which we separate NLSY79 respondents into two categories; the first group consists of the higher-IQ sibling (as measured using the Armed Forces Qualifying Test), the second consists of the lower-IQ sibling. We separate these analyses into father-father, mother-mother, and cross-gender categories. We run the following analyses. First, we compare the two groups on several fertility variables, including age at first intercourse, age at first birth, and completed fertility. This analysis assesses the size and direction of fitness status of IQ in this dataset. Second, we estimate several biometrical models that assess the biometrical status of the fertility outcomes in relation to maternal intelligence. We compare unconditional biometrical parameters to those conditioned on intelligence differences between the NLSY79 siblings. If the h2, c2, and e2 values are similar, then intelligence does not condition the biometrical structure of fertility outcomes. If they are statistically different, then intelligence is implicated as moderating the biometrical structure of fertility.
