Sensitivity and Security: New Questions to Ponder

The conclusion that parental sensitivity is a reliable—but not highly robust—predictor of a secure attachment invites reconsideration of the nature of sensitivity and its impact on early psychosocial development. Future directions for inquiry include (1) renewed attention to the growth of attachment in the context of other developing features of the parent-infant relationship, including play and behavioral management; (2) the factors that moderate the impact of sensitivity on developing security (including the contexts of sensitive responsiveness infant age, and the consistency of parental sensitivity over time); (3) the multifaceted and dyanamic origins of individual differences in sensitivity; and (4) greater consideration of why sensitivity fosters attachment security, especially in relation to emergent working models of relationships and self.     

Behavioral/emotional indicators of sexual abuse in child psychiatric inpatients: A controlled comparison with physical abuse

Several behavioral and emotional indicators of child sexual abuse were compared for both sexually (n = 29) and physically abused (n = 52) children from a sample of 103 hospitalized psychiatric patients. The measures included (1) scores from a factor-analyzed sexual abuse symptom checklist covering home/community behavior that was rated by parents during a clinical interview and (2) frequency counts of psychological symptoms exhibited by the children during a 3-week period of hospitalization. Results of a 2 (sexual abuse status) X 2 (physical abuse status) X 2 (gender) Multivariate Analysis of Variance indicated that sexually abused children exhibited greater sexual behavior, fear/mistrust/anxiety, and withdrawal at home, and greater sexual behavior, fear/anxiety, and sadness in the hospital than nonabused children. In contrast, there were no significant differences between physically abused and nonabused children, and no significant interactions. Few significant correlations were found between symptoms exhibited at home and in the hospital.     

Stigma and incest survivors

The impact of incestuous child sexual abuse continues to affect victims into their adult lives. Survey responses from college students indicate the predicted stigma surrounding this childhood event varies with gender as well as with length and type of relationship at the time of the disclosure. Women indicate differences in stigma when anticipating various types of relationships with male survivors. Particularly, women show dating as less comfortable than opposite sex friendship, and parenting as less comfortable than marriage. Men do not indicate these differences in stigma based on the type of relationship, but instead predict comfort with female survivors based on the length of relationship.     

Learning Neuroscience: An Interactive Case-Based Online Network (ICON)

We have developed an interactive case-based online network (ICON) that provides a new learning environment and integrates the student's thinking across the different concentration tracks of one of Harvard's interfaculty science initiatives. ICON takes advantage of this cross-disciplinary, undergraduate curriculum as a model system to bring a compelling, integrative focus to bear on reshaping how Harvard students learn neuroscience. ICON contains 9 learning modules specific to each case: Case, Working Papers, Blackboard, Neuroimaging, Research Programs and Trials, Decision Tree, Learning Objectives, Virtual Contact, and Brainstorm. Modules allow the student to get away from interpreting vast amounts of available information, move toward selecting useful information, recognize discriminating findings, and build a conceptual understanding of real and meaningful problems in neuroscience. The result is that ICON introduces a new landscape within the academic curriculum where the active participation of faculty and students effectively intersects and captures an immediate, integrative learning experience for the student. The benchmark of ICON is the time spent by students and faculty to create a user-defined learning network that engages faculty to participate in the students' learning and transforms the way the student thinks.     

Preschoolers’ Understanding of How Others Learn Through Action and Instruction

It is widely believed that exploration is a mechanism for young children's learning. The present investigation examines preschoolers’ beliefs about how learning occurs. We asked 3‐ to 5‐year‐olds to articulate how characters in a set of stories learned about a new toy. Younger preschoolers were more likely to overemphasize the role of characters’ actions in learning than older children were (Experiment 1, N = 53). Overall performance improved when the stories explicitly stated that characters were originally ignorant and clarified the characters’ actions, but general developmental trends remained (Experiment 2, N = 48). These data suggest that explicit metacognitive understanding of the relation between actions and learning is developing during the preschool years, which might have implications for how children learn from exploration.     

Regularized Structural Equation Modeling

A new method is proposed that extends the use of regularization in both lasso and ridge regression to structural equation models. The method is termed regularized structural equation modeling (RegSEM). RegSEM penalizes specific parameters in structural equation models, with the goal of creating easier to understand and simpler models. Although regularization has gained wide adoption in regression, very little has transferred to models with latent variables. By adding penalties to specific parameters in a structural equation model, researchers have a high level of flexibility in reducing model complexity, overcoming poor fitting models, and the creation of models that are more likely to generalize to new samples. The proposed method was evaluated through a simulation study, two illustrative examples involving a measurement model, and one empirical example involving the structural part of the model to demonstrate RegSEM’s utility.     

Cumulative environmental risk in substance abusing women: early intervention, parenting stress, child abuse potential and child development

OBJECTIVE: To assess the relationship between cumulative environmental risks and early intervention, parenting attitudes, potential for child abuse and child development in substance abusing mothers. METHOD: We studied 161 substance-abusing women, from a randomized longitudinal study of a home based early intervention, who had custody of their children through 18 months. The intervention group received weekly home visits in the first 6 months and biweekly visits from 6 to 18 months. Parenting stress and child abuse potential were assessed at 6 and 18 months postpartum. Children's mental and motor development (Bayley MDI and PDI) and language development (REEL) were assessed at 6, 12, and 18 months postpartum. Ten maternal risk factors were assessed: maternal depression, domestic violence, nondomestic violence, family size, incarceration, no significant other in home, negative life events, psychiatric problems, homelessness, and severity of drug use. Level of risk was recoded into four categories (2 or less, 3, 4, and 5 or more), which had adequate cell sizes for repeated measures analysis. DATA ANALYSIS: Repeated measures analyses were run to examine how level of risk and group (intervention or control) were related to parenting stress, child abuse potential, and children's mental, motor and language development over time. RESULTS: Parenting stress and child abuse potential were higher for women with five risks or more compared with women who had four or fewer risks; children's mental, motor, and language development were not related to level of risk. Children in the intervention group had significantly higher scores on the PDI at 6 and 18 months (107.4 vs. 103.6 and 101.1 vs. 97.2) and had marginally better scores on the MDI at 6 and 12 months (107.7 vs. 104.2 and 103.6 vs. 100.1), compared to the control group. CONCLUSION: Compared to drug-abusing women with fewer than five risks, women with five or more risks found parenting more stressful and indicated greater inclination towards abusive and neglectful behavior, placing their infants at increased risk for poor parenting, abuse and neglect. Early home-based intervention in high-risk families may be beneficial to infant development.     

Motivation and studying in high school science

Three groups of high school science students (college-bound and non-college-bound freshmen, college-bound juniors and seniors) completed surveys measuring their beliefs in the utility of four kinds of study strategies, three types of motivational orientation to science (task orientation, ego orientation, and work avoidance), their reported ability, and attitude toward science. Results indicated that belief in the usefulness of strategies requiring deep processing of information was more strongly positively related to task orientation than to ego orientation in all groups. For the younger groups only, task orientation was positively related to belief in the utility of surface-level strategies (e.g., rote memorization of facts). Task orientation proved to be the best predictor of student beliefs in deep-processing strategies, above and beyond that explained by perceived ability and interest in science. The implications of these findings for the current and future goals of science educators are discussed.     

Supported playgroups in schools: bonding and bridging family knowledge about transition to formal schooling

Supported Playgroups in Schools (SPinS) are a new initiative in the Australian early childhood education landscape. SPinS are playgroups hosted by a playgroup coordinator co-located on a local school site. Research has identified positive benefits of playgroup participation for children and families. However, little is known about the potential for SPinS to contribute to families’ knowledge about transition to formal schooling. This paper uses the social capital concepts of ‘bonding’ and ‘bridging’ to examine caregivers’ perspectives on their participation in a SPinS with potential to build parental knowledge about their child’s transition to formal schooling. Three main elements of caregivers’ participation in SPinS with such potential are identified, and these elements are mapped into a continuum of low-to-high bonding and bridging relationships to illustrate the potential for SPinS to contribute to the development of increased knowledge about transition to formal schooling by families of young children.
