Examining Estimates of Intervention Effectiveness Using Sensitivity Analysis

Making causal inferences from a quasi‐experiment is difficult. Sensitivity analysis approaches to address hidden selection bias thus have gained popularity. This study serves as an introduction to a simple but practical form of sensitivity analysis using Monte Carlo simulation procedures. We examine estimated treatment effects for a school‐based support intervention designed to address student strengths and needs in academic and nonacademic areas by leveraging partnerships with community agencies. Middle school (Grades 6–8) statewide standardized test scores in mathematics and English language arts (ELA) were examined for students in a large urban district who participated in City Connects during elementary school. Results showed that the estimated treatment effects in both subjects were reduced slightly with the inclusion of U, a hypothesized unobserved binary variable. However, simulated effects fell within one‐sided 90% confidence intervals for original treatment effects, suggesting only a mild sensitivity to hidden bias. Moreover, almost identical estimated treatment effects were observed when the magnitude of the mathematical difference between each pair of the conditional probabilities of U given the treatment indicator Z was the same.     

Neural Correlates of Children's Theory of Mind Development

Young children show significant changes in their mental-state understanding as marked by their performance on false-belief tasks. This study provides evidence for activity in the prefrontal cortex associated with the development of this ability. Event-related brain potentials (ERPs) were recorded as adults ( N  = 24) and 4-, 5-, and 6-year-old children ( N  = 44) reasoned about reality and the beliefs of characters in animated vignettes. In adults, a late slow wave (LSW), with a left-frontal scalp distribution, was associated with reasoning about beliefs. This LSW was also observed for children who could correctly reason about the characters' beliefs but not in children who failed false-belief questions. These findings have several implications, including support for the critical role of the prefrontal cortex for theory of mind development.     

Neural Correlates of Belief- and Desire-Reasoning

Theory of mind requires an understanding of both desires and beliefs. Moreover, children understand desires before beliefs. Little is known about the mechanisms underlying this developmental lag. Additionally, previous neuroimaging and neurophysiological studies have neglected the direct comparison of these developmentally critical mental-state concepts. Event-related brain potentials were recorded as participants ( N  =   24; mean age   =   22 years) reasoned about diverse-desires, diverse-beliefs, and parallel physical situations. A mid-frontal late slow wave (LSW) was associated with desire and belief judgments. A right-posterior LSW was only associated with belief judgments. These findings demonstrate neural overlap and critical differences in reasoning explicitly about desires and beliefs, and they suggest children recruit additional neural processes for belief judgments beyond a common, more general, mentalizing neural system.     

Children's Early Awareness of Comprehension as Evident in Their Spontaneous Corrections of Speech Errors

A crucial human cognitive goal is to understand and to be understood. But understanding often takes active management. Two studies investigated early developmental processes of understanding management by focusing on young children's comprehension monitoring. We ask: When and how do young children actively monitor their comprehension of social-communicative interchanges and so seek to clarify and correct their own potential miscomprehension? Study 1 examined the parent–child conversations of 13 children studied longitudinally in everyday situations from the time the children were approximately 2 years through 3 years. Study 2 used a seminaturalistic situation in the laboratory to address these questions with more precision and control with 36 children aged 2–3 years.     

FROM NEAR‐RUBBLE TO REBIRTH: A FORMER CHURCH BUILDING AS A CENTERPIECE OF COLLABORATION FOR CHILDREN

This article describes the collaborative efforts of multiple organizations and individuals in transforming a doomed church in a large urban community into an exemplary public Pre‐k through Grade 2 laboratory school. Central to this emerging facility was the commitment of all cooperating parties to focus upon meeting the educational, health, and social needs of each child through school, home and community involvement. Unique to this collaboration has been the continual involvement of higher education institutions in Western New York in the planning, organization and implementation of this project. Further, infusion of the latest in computer and video technology with distance learning capability supported cross‐fertilization and friendships among higher education professionals and their students from a variety of related disciplines.
