The Effects of Children’s Health on Mothers’ Employment

When children have health problems, mothers face a tradeoff between the decision to work to satisfy increased expenses and the decision to stay home to fulfill enlarged caregiving needs, especially for children with chronic conditions. This research used an instrumental variables approach to investigate the labor market consequences of mothers due to burden to care children with health problems. We found mothers’ employment probability increased by 0.9% for every $100 of increased out-of-pocket medical spending, while employment probability fell by 1.0% for every half day of school/day care a sick child missed. By correcting for endogeneity we addressed a potential empirical bias. Analyses by subgroups showed that Hispanic mothers were less likely to work in the labor market with high caregiving burden. We also found that the effects of time burden on labor market outcomes were magnified for black mothers.     

The Long-Run Effects of Job Displacement on Sources of Health Insurance Coverage

This paper examines job displacement’s long-run effect on health insurance coverage and source of coverage. We find that displacement lowers the probability that an individual receives health insurance even ten years after job loss. However, those without children at the time of job loss largely drive this result. While displaced workers with and without children face similar losses in access to employer-provided health insurance, those with children mostly offset these losses by acquiring health insurance from other sources, particularly through the increased use of Medicaid.     

The Effects of Praising Qualifying Autoclitics on the Frequency of Reading

In the current study, tacts with positive qualifying autoclitics for reading were reinforced in order to determine if this procedure would increase the time spent reading by participants. Participants included 5 children, between 9–10 years old. Participants were individually exposed to 4 free operant sessions during which they were instructed to independently choose play activities. During pre- and post-treatment conditions, no consequences were provided for choosing reading. In addition, 4 treatment sessions were conducted on days separate from the free operant session days, during which the experimenter praised each positive reading-related statement emitted by the participant. Following treatment sessions, 4 out of 5 participants increased the time allocated to reading, suggesting that reading could be increased when praise is delivered contingent upon positive reading-related verbalizations.     

Effects of early support intervention on workplace ergonomics--a two-year followup study

The purpose of the controlled longitudinal study was to determine the effect of a tailored early support intervention method on workers' workplace ergonomics. The main areas of the early support intervention were training, guidance and support for supervisors in finding weak signals of impaired ergonomics. Supervisors were also trained to bring up these weak signals in discussion with employees and to make necessary changes at the workplace. The data consisted of 301 intervention subjects and 235 control subjects working in the field of commerce. The questionnaires were carried out in 2008 and in 2010, and the response rates among both groups were 45%. We used multivariate repeated measures analysis of variance (MANOVA) to test the difference in the groups at two points of time. The main result was that in the areas of work environment, the interaction between group and time was statistically significant (p=0.0004). The work environment improved in the intervention group, but deteriorated in the control. Working methods improved due to the interventions, but physical load factors increased over time in both groups. According to the study, tailored early support intervention has a generally beneficial impact on workers' workplace ergonomics in the areas of work methods, work environment and accident factors.     

The Effect of Heterogeneity on Numerical Ordering in Rhesus Monkeys

We investigated how within‐stimulus heterogeneity affects the ability of rhesus monkeys to order pairs of the numerosities 1 through 9. Two rhesus monkeys were tested in a touch screen task where the variability of elements within each visual array was systematically varied by allowing elements to vary in color, size, shape, or any combination of these dimensions. We found no evidence of a cost (or benefit) in accuracy or reaction time when monkeys were tested with stimuli that were heterogeneous in color, size, or shape. This was true even though both monkeys experienced extended initial training with arrays that were homogeneous in the color, shape, and size of elements. The implications of this finding for the mechanisms that monkeys use to represent and compare numerosities are discussed.     

Trajectories of Depressed Mood From Early Adolescence to Young Adulthood: The Effects of Pubertal Timing and Adolescent Dating

The effects of pubertal timing and adolescent dating on trajectories of depressed mood from early adolescence to young adulthood were examined among youths who participated in the National Longitudinal Study of Adolescent Health. Results showed that for both boys and girls, the trajectories of depressed mood between the ages of 12 and 23 took an inverse U‐shape with its peak in mid‐adolescence. Furthermore, pubertal timing was a significant predictor of depressed mood at age 12. The pubertal timing effect was nonlinear, suggesting that at age 12, early and late maturing youths were at risk of experiencing elevated levels of depressed mood. The adverse effect of off‐time maturation gradually dissipated over time. Moreover, in early adolescence, teenagers, particularly girls, were adversely affected by dating, and off‐time physical maturation exacerbated the negative effects of dating. However, the interactive effect of dating and pubertal timing gradually decreased with age. Our findings underscore the importance of examining junctures of biological and social challenges in adolescence to gain better understandings of young people's emotional experiences over time.     

Cohabitation and Housework: The Effects of Marital Intentions

This study asks how cohabiters’ housework patterns vary by their marital intentions. I draw on interactionist theories that view housework as an activity that produces gender and family to hypothesize that cohabiters who are more invested in their relationships will spend more time on housework. Analyzing the 1987–1988 National Survey of Families and Households (N = 348), I find that, controlling for sociodemographic and household differences, men who are least committed to their relationships spend the least time on housework, whereas women's housework time is not affected by marital intentions.     

The Effects of Social Interaction and Personal Relationships on Facial Expressions

Previous studies have reported that the expression of smiles is facilitated by social interaction between partners. We examined the effects of social interaction and personal relationships on facial expressions in Japan. Pairs of friends and strangers seated next to each other (the no partition condition) or separated by a partition (the partition condition) were shown film clips aimed to elicit either positive or negative affect. Smiles were facilitated in the no partition condition in which participants interacted with each other. Further, the effect of social interaction on frowns differed depending on whether pairs were friends or strangers.     

The Effects of Distraction on Cognitive Task Performance During Toddlerhood

We investigated the effects of distraction on attention and task performance during toddlerhood. Thirty toddlers (24‐ to 26‐month‐olds) completed different tasks (2 of each: categorization, problem solving, memory, free play) in one of two conditions: No Distraction or Distraction. The results revealed that the distractor had varying effects on performance scores depending on the task: The problem solving and memory tasks were more susceptible to distraction. In addition, the two conditions showed different patterns of attention over time. Toddlers in the No Distraction condition were more attentive, and their attention remained consistently high across the session. Toddlers in the Distraction condition increased their attention to the task and decreased their attention to the distractor in the second half of the session. This study demonstrates how the presence of distraction influences toddlers’ performance on individual cognitive tasks and contributes to our understanding of distractibility and endogenous attention during toddlerhood. This work also has implications for how environmental noise, such as background television, may influence cognitive development.     

The ebb and flow of marital lust: a relational approach

This diary study examined daily fluctuation in marital lust over a 56-day period. The purposes of the study were to describe typical patterns of lust over time and to examine intrapersonal and interpersonal associations between relationship affect, relationship states, and marital lust. We also tested various daily moderational predictions. Four patterns of daily fluctuation in lust were identified. Typical patterns varied from almost no fluctuation to wide fluctuation over time. Our findings showed that daily affect was generally related to lust both within partners and between partners. Also, spouses relational states (closeness and equality of power) moderated several of these intrapersonal and interpersonal associations. In general, the affect-lust link was strengthened by closeness and equality of power, while the lust-lust link between spouses was often conditioned by both relationship affect and relational states. However, the role of negative affect toward spouses in interactions with other constructs was not as expected. We discuss possible explanations for the findings and implications for further research.     

The Effects of Calibration Target,Screen Location,and Movement Type on Infant Eye‐Tracking Data Quality

During infant eye‐tracking, fussiness caused by the repetition of calibration stimuli and body movements during testing are frequent constraints on measurement quality. Here, we systematically investigated these constraints with infants and adults using EyeLink 1000 Plus. We compared looking time and dispersion of gaze points elicited by stimuli resembling commonly used calibration animations. The adult group additionally performed body movements during gaze recording that were equivalent to movements infants spontaneously produce during testing. In our results, infants’ preference for a particular calibration target did not predict data quality elicited by that stimulus, but targets exhibiting the strongest contrasts in their center or targets with globally distributed complexity resulted in the highest accuracy. Our gaze measures from the adult movement tasks were differentially affected by the type of movement as well as the location where the target appeared on the screen. These heterogeneous effects of movement on measures should be taken into account when planning infant eye‐tracking experiments. Additionally, to improve data quality, infants’ tolerance for repeated calibrations can be facilitated by alternating between precise calibration targets.     

The Effects of Early Maternal Employment on Later Cognitive and Behavioral Outcomes

This article investigates the long‐term impact of early maternal employment on children's cognitive and behavioral outcomes. Non‐Hispanic White and African American children aged 3 to 4 in the 1986 National Longitudinal Survey of Youth were followed longitudinally to see whether the effects that prior studies found at age 3 to 4 persist into the school‐age years (ages 7 to 8) or whether those effects attenuate over time. The empirical results indicate that maternal employment in the 1st year of a child's life has significant negative effects on White children's cognitive outcomes. These effects persist to ages 7 or 8 for some children but not for others. We also found some negative effects of maternal employment in the 1st year on behavioral problems as assessed at age 7 or 8, but again these effects are found only for White children.

The Long‐Term Effects of Caregiving on Women's Health and Mortality

Caregivers experience numerous mental and physical health effects from the stress of providing care, but we know little about whether these problems persist in the long term and whether long‐term effects differ across caregiving contexts. Using the National Longitudinal Survey of Mature Women, we examined the relationship between caregiving and long‐term patterns of depressive symptoms, functional limitations, and mortality. We also explored the health effects of caregiving in‐home versus out‐of‐home and by caregiver/care‐recipient relationship. Analyses show that in‐home spousal and parental caregiving predict increased depressive symptoms and functional limitations in the long term but are unassociated with mortality, whereas caregiving outside the home is unassociated with later depression and functional limitations but predicts a lower risk of mortality. This study highlights the usefulness of approaching stressful experiences such as caregiving from the life course perspective, viewing them as processes that unfold over time within specific contexts that may carry delayed or cumulative consequences.     

Are Divorce Studies Trustworthy? The Effects of Survey Nonresponse and Response Errors

Researchers rely on relationship data to measure the multifaceted nature of families. This article speaks to relationship data quality by examining the ramifications of different types of error on divorce estimates, models predicting divorce behavior, and models employing divorce as a predictor. Comparing matched survey and divorce certificate information from the 1995 Life Events and Satisfaction Study (N = 1,811) showed that nonresponse error is responsible for the majority of the error in divorce data. Misreporting the divorce event was rare, and more than two thirds of respondents provided a divorce date within 6 months of the actual date. Nevertheless, divorce date error attenuated effects of time since divorce on outcomes. Gender, child custody, marital history, and education were associated with divorce error.     

Romantic Attachment Among Young Adults: The Effects of Parental Divorce and Residential Instability

Using an attachment theory perspective, variation in adult romantic attachment style outcomes were examined according to childhood experiences of parental divorce and residential instability. The sample was made up of 172 young adults who were recruited using snowball sampling via online social networking. A statistical difference on adult romantic attachment style was not found between individuals who experience parental divorce and those who did not, and parental conflict and stability of residence patterns did not have a statistical impact on attachment avoidance or anxiety. However, conflict, residential stability, and time with nonresidential parent statistically improved the predictive ability of attachment anxiety among those whose parents had divorced. Specifically, time with nonresidential parent moderated adult romantic attachment anxiety.     

Golden Years? The Labor Market Effects of Caring for Grandchildren

The number of Americans raising grandchildren has been rising steadily. In this article, we expand what is known by focusing on the economic implications of this trend. We compile a unique data set from the Panel Study of Income Dynamics along with its Parent Identification File on 3,240 nonretired grandparent household heads and estimate the effect of taking in a grandchild on labor force participation and hours worked. We estimate models that distinguish between grandparents living alone from those only with grandchildren (skipped‐generation households) and those also with their own children (3‐generation households). We find that caring for grandchildren increases labor force attachment, with grandfathers more likely to work and grandmothers working longer, if another adult is available to supervise the grandchildren.     

The Association of Birth Complications and Externalizing Behavior in Early Adolescents: Direct and Mediating Effects

Prior studies have shown that birth complications interact with psychosocial risk factors in predisposing to increased externalizing behavior in childhood and criminal behavior in adulthood. However, little is known about the direct relationship between birth complications and externalizing behavior. Furthermore, the mechanism by which the birth complications predispose to externalizing behavior is not well explored. This study aims to assess whether birth complications predispose to early adolescent externalizing behavior and to test whether Intelligence Quotient (IQ) mediates relationships between predictor and outcome variables. We used data from a prospective, longitudinal birth cohort of 1,795 3-year-old boys and girls from Mauritius to test hypotheses. Birth complications were assessed from hospital record data, malnutrition from a pediatric exam at age 3 years, psychosocial adversity from parental interviews at age 3 years, and externalizing behavior problems from parental ratings at age 11 years. We found that babies with birth complications are more likely to develop externalizing behavior problems at age 11. Low IQ was associated with birth complications and was found to mediate the link between early predictors and later externalizing behavior. These prospective, longitudinal findings have potential clinical implications for the identification of early adolescent externalizing behavior and for public health attempts to prevent the occurrence of child externalizing behavior problems.     

The Effects of Family Structure on African American Adolescents' Marijuana Use

The relationship between family structure and marijuana use throughout adolescence was assessed among 1,069 African Americans from the NLSY. A model was also tested suggesting that the effects of family structure on marijuana use would be mediated by poverty, neighborhood quality, and adolescents' self‐control. As most prior studies have found, family structure was not related to female adolescents' marijuana use. For young men, being raised with both biological parents was associated with less marijuana use throughout adolescence compared to those whose mothers never married, divorced early and never remarried, or divorced and remarried. Some support for the model was also found. We concluded that being raised without the presence of a biological father is a risk factor for marijuana use among young men, but African American young women from single‐parent households have unique resources that protect them from marijuana use. Understanding those resources may offer insight into prevention programs for other youth.     

The Effects of Alcohol in Breast Milk on Infant Behavioral State and Mother‐Infant Feeding Interactions

The short‐term impact of infant exposure to alcohol in breast milk on mother‐infant interactions and infant arousal was examined. Fourteen mother‐infant dyads were tested on 2 occasions that consisted of an alcohol administration and a nonalcohol condition. Mother‐infant interactions during feeding were videotaped and coded for dyadic reciprocity, maternal noncontingency, and dyadic conflict. Infants were observed for 1 hr after receiving either plain breast milk or breast milk containing alcohol. Behavioral state, startles, and tremors were recorded every 30 sec. Mother‐infant interactions were characterized by higher noncontingency and dyadic conflict in the alcohol condition. After drinking breast milk containing alcohol, infants changed behavioral state more often, startled more, and spent less time in quiet sleep and more time in quiet alert and crying states. These findings suggest that exposure to breast milk containing alcohol may not have a sedating effect, as commonly believed.
