Socioeconomic risk moderates the link between household chaos and maternal executive function

We examined the link between household chaos (i.e., noise, clutter, disarray, lack of routines) and maternal executive function (i.e., effortful regulation of attention and memory), and whether it varied as a function of socioeconomic risk (i.e., single parenthood, lower mother and father educational attainment, housing situation, and father unemployment). We hypothesized that: 1) higher levels of household chaos would be linked with poorer maternal executive function, even when controlling for other measures of cognitive functioning (e.g., verbal ability), and 2) this link would be strongest in the most socioeconomically distressed or lowest-socioeconomic status households. The diverse sample included 153 mothers from urban and rural areas who completed a questionnaire and a battery of cognitive executive function tasks and a verbal ability task in the laboratory. Results were mixed for Hypothesis 1, and consistent with Hypothesis 2. Two-thirds of the variance overlapped between household chaos and maternal executive function, but only in families with high levels of socioeconomic risk. This pattern was not found for chaos and maternal verbal ability, suggesting that the potentially deleterious effects of household chaos may be specific to maternal executive function. The findings implicate household chaos as a powerful statistical predictor of maternal executive function in socioeconomically distressed contexts.

Property content guides children’s memory for social learning episodes

How do children’s interpretations of the generality of learning episodes affect what they encode? In the present studies, we investigated the hypothesis that children encode distinct aspects of learning episodes containing generalizable and non-generalizable properties. Two studies with preschool (N = 50) and young school-aged children (N = 49) reveal that their encoding is contingent on the generalizability of the property they are learning. Children remembered generalizable properties (e.g., morphological or normative properties) more than non-generalizable properties (e.g., historical events or preferences). Conversely, they remembered category exemplars associated with non-generalizable properties more than category exemplars associated with generalizable properties. The findings highlight the utility of remembering distinct aspects of social learning episodes for children’s future generalization.     

Losing face: impaired discrimination of featural and configural information in the mouth region of an inverted face

Given that all faces share the same set of features—two eyes, a nose, and a mouth—that are arranged in similar configuration, recognition of a specific face must depend on our ability to discern subtle differences in its featural and configural properties. An enduring question in the face-processing literature is whether featural or configural information plays a larger role in the recognition process. To address this question, the face dimensions task was designed, in which the featural and configural properties in the upper (eye) and lower (mouth) regions of a face were parametrically and independently manipulated. In a same–different task, two faces were sequentially presented and tested in their upright or in their inverted orientation. Inversion disrupted the perception of featural size (Exp. 1), featural shape (Exp. 2), and configural changes in the mouth region, but it had relatively little effect on the discrimination of featural size and shape and configural differences in the eye region. Inversion had little effect on the perception of information in the top and bottom halves of houses (Exp. 3), suggesting that the lower-half impairment was specific to faces. Spatial cueing to the mouth region eliminated the inversion effect (Exp. 4), suggesting that participants have a bias to attend to the eye region of an inverted face. The collective findings from these experiments suggest that inversion does not differentially impair featural or configural face perceptions, but rather impairs the perception of information in the mouth region of the face.     

The Role of Stress Exposure and Family Functioning in Internalizing Outcomes of Urban Families

Although research suggests that stress exposure and family functioning are associated with internalizing problems in adolescents and caregivers, surprisingly few studies have investigated the mechanisms that underlie this association. To determine whether family functioning buffers the development of internalizing problems in stress-exposed families, we assessed the relation between stress exposure, family functioning, and internalizing symptoms among a large sample of inner-city male youth and their caregivers living in poverty across five waves of data collection. We hypothesized that stress exposure and family functioning would predict development of subsequent youth and caregiver internalizing problems and that family functioning would moderate this relation, with higher functioning families demonstrating greater resiliency to stress exposure. We used a longitudinal, prospective design to evaluate whether family functioning (assessed at waves one through four) activated or buffered the effects of stress exposure (assessed at wave one) on subsequent internalizing symptoms (assessed at waves four and five). Stress from Developmental Transitions and family functioning were significant predictors of depressive symptoms and anxiety in youth; however, family functioning did not moderate the relation. Family functioning mediated the relation between stress from Daily Hassles and internalizing outcomes suggesting that poor parenting practices, low structure, and low emotional cohesion activate depression and anxiety in youth exposed to chronic and frequent everyday stressors. Surprisingly, only family functioning predicted depressive symptoms in caregivers. Results validate the use of a comprehensive, multi-informant assessment of stress when investigating internalizing outcomes in youth and support using family-based interventions in the treatment and prevention of internalizing.     

Auditory and visual hallucinations in a sample of severely mentally ill Puerto Rican women: an examination of the cultural context

The content, interpretation, and structure of hallucinations experienced by individuals with severe mental illness are influenced by the culture of the individuals who experience them. We analyzed the content of visual and auditory hallucinations of 53 Puerto Rican women in northeastern Ohio with a diagnosis of a severe mental illness (SMI) who were participating in a study of HIV risk among Hispanic women with SMI. Compared to non-hallucinators, hallucinators had lower global assessment of functioning scores and greater suicidality. Hallucinations reflected three themes: religious themes, command hallucinations, and unidentifiable voices. Hallucinators’ subjective experience of their hallucinations ranged from a sense of security to significant distress. Participants developed a wide range of strategies to deal with threatening hallucinations. Provider response to individuals’ experience appeared to impact the quality of the patient–provider relationship. We recommend the inclusion of religious history in the initial assessment of individuals. This will assist the provider in making an accurate diagnosis, distinguishing between religious beliefs and those that reflect underlying pathology, and in increasing the level of cultural competence of the care provided. Religious and spiritual beliefs that provide a source of hope and strength for the patient can be utilized to expand and enhance the patient's coping strategies.     

Associations between Temperament and Social Responsiveness in Young Children

Recent research has demonstrated that social responsiveness (comprised of social awareness, social information processing, reciprocal social communication, social motivation, and repetitive/restricted interests) is continuously distributed within the general population. In the present study, we consider temperament as a co‐occurring source of individual differences in social responsiveness in young children. The sample consisted of 62 infants assessed at 2, 3, and 4 years old. Measures of temperament were obtained at each age (Early Childhood Behavior Questionnaire and Children's Behavior Questionnaire), and social responsiveness was measured at 4 years old (Social Responsiveness Scale). Multivariate patterns of association between components of temperament and social responsiveness were observed at each age, with overall findings in line with the broader literature examining temperament and socio‐development associations. Importantly, these results provide support for the usefulness of temperament as a relevant source of variability in social responsiveness, as measured by the Social Responsiveness Scale, in typically developing young children.

Fetal Testosterone,Socio‐Emotional Engagement and Language Development

The present study investigated the relations among fetal testosterone, child socio‐emotional engagement and language development in a sample of 467 children (235 boys) from the Western Australian Pregnancy Cohort (Raine) Study. Bioavailable testosterone concentration measured in umbilical cord blood taken at birth was found to be significantly negatively correlated with socio‐emotional engagement and vocabulary development for boys but not for girls. Socio‐emotional engagement mediated the effect of boys' fetal testosterone levels on their vocabulary development. However, the size of the effects was small, and fetal testosterone and socio‐emotional engagement were no longer significant predictors of boys' vocabulary scores after accounting for the effects of other predictors including maternal age and education, parity, and parent–child book reading. It is concluded that further research into these associations is warranted in both typical and atypical development and that this research would profit from including a broader focus on the role that proximal processes such as socio‐emotional engagement, joint attention and imitation have in mediating the developmental effects of prenatal factors such as fetal testosterone exposure.

This article discusses some of the reasons why cognitive developmental researchers might wish to conduct research in schools, describes how to get started conducting research in schools, and offers advice to help make school-based research proceed more smoothly.     

Children's Acquisition of Arithmetic Principles: The Role of Experience

The current study investigated how young learners' experiences with arithmetic equations can lead to learning of an arithmetic principle. The focus was elementary school children's acquisition of the Relation to Operands principle for subtraction (i.e., for natural numbers, the difference must be less than the minuend). In Experiment 1, children who viewed incorrect, principle-consistent equations and those who viewed a mix of incorrect, principle-consistent and principle-violation equations both showed gains in principle knowledge. However, children who viewed only principle-consistent equations did not. We hypothesized that improvements were due in part to improved encoding of relative magnitudes. In Experiment 2, children who practiced comparing numerical magnitudes increased their knowledge of the principle. Thus, experience that highlights the encoding of relative magnitude facilitates principle learning. This work shows that exposure to certain types of arithmetic equations can facilitate the learning of arithmetic principles, a fundamental aspect of early mathematical development.
