Children's temperament and behavior problems predict their employed mothers' work functioning

Numerous studies have been conducted on the impact of dual-earner parents' employment on their children, yet the reverse process-the impact of children and their behavior on the work functioning of their parents-has been ignored. This study investigated spillover from the mother role to the work role in a sample of more than 300 families. At 4 months, 12 months, 3.5 years, and 4.5 years of age, child's difficult temperament was significantly associated with mother's work outcomes, including work role quality and rewards from combining work and family. The evidence was consistent with a structural model in which maternal sense of parenting competence and maternal depressed affect mediated these effects.     

Depression and Anxiety in the Postnatal Period: An Examination of Infants’ Home Language Environment,Vocalizations, and Expressive Language Abilities

This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability.     

Culturally Diverse Undergraduate Researchers’ Academic Outcomes and Perceptions of Their Research Mentoring Relationships

Few studies have empirically investigated the specific factors in mentoring relationships between undergraduate researchers (mentees) and their mentors in the biological and life sciences that account for mentees’ positive academic and career outcomes. Using archival evaluation data from more than 400 mentees gathered over a multi-year period (2005–2011) from several undergraduate biology research programs at a large, Midwestern research university, we validated existing evaluation measures of the mentored research experience and the mentor–mentee relationship. We used a subset of data from mentees (77% underrepresented racial/ethnic minorities) to test a hypothesized social cognitive career theory model of associations between mentees’ academic outcomes and perceptions of their research mentoring relationships. Results from path analysis indicate that perceived mentor effectiveness indirectly predicted post-baccalaureate outcomes via research self-efficacy beliefs. Findings are discussed with implications for developing new and refining existing tools to measure this impact, programmatic interventions to increase the success of culturally diverse research mentees and future directions for research.     

Evaluating and Approaching a Strange Animal: Children's Trust in Informant Testimony

This study examined 3‐ to 7‐year‐old children's reliance on informant testimony to learn about a novel animal. Sixty participants were given positive or negative information about an Australian marsupial from an informant described as a maternal figure or a zookeeper. Children were asked which informant was correct and were invited to touch the animal, which was a stuffed toy hidden in a crate. Overall, younger children endorsed the zookeeper's testimony about the animal, but touched the animal more readily when the maternal figure provided positive information. Older children endorsed the informant who provided positive information, but showed some sensitivity to zookeeper expertise. Age differences were obtained in the association between participant characteristics and informant selection and animal approach behavior.
