Children’s Gender-Typed Behavior from Early to Middle Childhood in Adoptive Families with Lesbian,Gay, and Heterosexual Parents

Gender-typed behaviors—both gender-conforming and nonconforming—were investigated longitudinally among children in 106 adoptive U.S. families with lesbian, gay, and heterosexual parents at two times (Wave 1, preschool-age; Wave 2, school-age) over 5 years. At Wave 1 (W1), parents reported on children’s gender-typed behavior using the Pre-School Activities Inventory (PSAI; Golombok and Rust 1993), and children’s gender-typed toy play was evaluated using observational methods. At Wave 2 (W2), children reported on their own gender-typed behavior using the Children’s Occupations, Activities, and Traits Personal Measure (COAT-PM; Liben and Bigler 2002). Observations of children’s gender-conforming toy play and parents’ reports of children’s gender nonconformity (PSAI) in early childhood (W1) were associated with children’s self-reports of gender nonconformity (COAT-PM) in middle childhood (W2); toy play was most strongly predictive of gender nonconformity 5 years later. Children’s gender-typed behavior also varied by age and gender at both time points, but no significant differences were found as a function of parental sexual orientation across time. Informative to ongoing debates about same-sex parenting, our findings indicate that among children reared by lesbian, gay, and heterosexual parents, gender-typing appears to be similar, and predominantly gender-conforming, across early to middle childhood.

Rules or connections in past-tense inflections: what does the evidence rule out?

Pinker and colleagues propose two mechanisms - a rule system and a lexical memory - to form past tenses and other inflections. They predict that children's acquisition of the regular inflection is sudden; that the regular inflection applies uniformly regardless of phonological, semantic or other factors; and that the rule system is separably vulnerable to disruption. A connectionist account makes the opposite predictions. Pinker has taken existing evidence as support for his theory, but the review of the evidence presented here contradicts this assessment. Instead, it supports all three connectionist predictions: gradual acquisition of the past tense inflection; graded sensitivity to phonological and semantic content; and a single, integrated mechanism for regular and irregular forms, dependent jointly on phonology and semantics.     

Integration of faces and voices, but not faces and names, in person recognition

Recent studies on cross-modal recognition suggest that face and voice information are linked for the purpose of person identification. We tested whether congruent associations between familiarized faces and voices facilitated subsequent person recognition relative to incongruent associations. Furthermore, we investigated whether congruent face and name associations would similarly benefit person identification relative to incongruent face and name associations. Participants were familiarized with a set of talking video-images of actors, their names, and their voices. They were then tested on their recognition of either the face, voice, or name of each actor from bimodal stimuli which were either congruent or novel (incongruent) associations between the familiarized face and voice or face and name. We found that response times to familiarity decisions based on congruent face and voice stimuli were facilitated relative to incongruent associations. In contrast, we failed to find a benefit for congruent face and name pairs. Our findings suggest that faces and voices, but not faces and names, are integrated in memory for the purpose of person recognition. These findings have important implications for current models of face perception and support growing evidence for multisensory effects in face perception areas of the brain for the purpose of person recognition.     

Look, no hands!

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities are necessary for tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.     

Leisure activities, caregiving demands and catecholamine levels in dementia caregivers

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n?=?107; mean age?=?73.95?±?8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post?hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β?=?0.41; p?=?0.005) and EPI (β?=?0.44; p?=?0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β?=?-0.08; p?=?0.57) or EPI (β?=?0.23; p?=?0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.     

The causal role of phoneme awareness and letter-sound knowledge in learning to read: combining intervention studies with mediation analyses

There is good evidence that phoneme awareness and letter-sound knowledge are reliable longitudinal predictors of learning to read, though whether they have a causal effect remains uncertain. In this article, we present the results of a mediation analysis using data from a previous large-scale intervention study. We found that a phonology and reading intervention that taught letter-sound knowledge and phoneme awareness produced significant improvements in these two skills and in later word-level reading and spelling skills. Improvements in letter-sound knowledge and phoneme awareness at the end of the intervention fully mediated the improvements seen in children's word-level literacy skills 5 months after the intervention finished. Our findings support the conclusion that letter-sound knowledge and phoneme awareness are two causal influences on the development of children's early literacy skills.
