The purpose of this study was to explore how social support, mother's psychological status, and maternal sensitivity affected attachment security in children with disabilities by using the structural equation model (SEM). Subjects were 141 pairs of children with disabilities and theirs mothers. Empirical data was obtained through a series of…

Two cohorts of alumni, leading-edge and trailing-edge baby boomers, first tested in their college years, were followed to ages 43 (N = 136) and 54 (N = 182) on a measure of Erikson's theory of psychosocial development. Hierarchical linear modeling was used to model the trajectory of growth for each psychosocial issue across middle adulthood. As…

Quality of life (QOL) has emerged over the past 20 years as an outcome for measuring the effectiveness of health-improvement interventions. The Cerebral Palsy Quality of Life Questionnaire for Children (CPQOL-Child) is well regarded and now integrated into research internationally. We describe the results of qualitative research, using grounded…

This article examines developmental trends in the rates of different kinds of victimization across the span of childhood. The Developmental Victimization Survey was a national telephone survey of the victimization experiences of 2,030 children from ages 2 to 17. The overall mean number of victimizations during a single year increased with age, as…

Both the polyvalent notions of culture and development have been central for building psychological theories. In the present paper, both notions are discussed within the framework of general developmental science and thus from a necessarily systemic perspective. Development is surely culturally informed, yet the process of cultivation is largely…

Purpose: This investigation aimed to examine the development of tongue-jaw coordination during speech from childhood to adolescence. Method: Electromagnetic articulography was used to track tongue and jaw motion in 48 children and adults (aged 6-38 years) during productions of /t/ and /k/ embedded in sentences. Results: The coordinative…

The notion that phenotypic traits, including behavior, can be predetermined has slowly given way in biology and psychology over the last two decades. This shift in thinking is due in large part to the growing evidence for the fundamental role of developmental processes in the generation of the stability and variations in phenotype that researchers…

Children rely extensively on others' testimony to learn about the world. However, they are not uniformly credulous toward other people. From an early age, children's reliance on testimony is tempered by selective trust in particular informants. Three- and 4-year-olds monitor the accuracy or knowledge of informants, including those that are…

It is becoming increasingly clear that little in development is predetermined or permanently fixed. Rather, gene expression is activity dependent, and epigenesis is probabilistic. So, the study of genetic disorders needs to change from the still widely held view that developmental disorders can be accounted for in terms of intact versus impaired…

During the second year of life, infants exhibit a "video deficit effect." That is, they learn significantly less from a televised demonstration than they learn from a live demonstration. We predicted that repeated exposure to televised demonstrations would increase imitation from television, thereby reducing the video deficit effect. Independent…

Recent deferred imitation experiments are shedding new light onto the development of declarative memory during early infancy and revealing interesting new facets, for example, that infants process novel information on more than one level. In the current study with 13-month-old infants we examined relational information processing of novel,…

The present study examined conceptions of "what makes an adult" within a sample of adolescents (13-19 years) from divorced families. Arnett's (2003) seven criteria-of-adulthood categories (independence, interdependence, role transitions, norm compliance, biological transitions, chronological transitions, and family capacities) were used as an…

Language acquisition research in autism has traditionally focused on high-level pragmatic deficits. Few studies have examined grammatical abilities in autism, with mixed findings. The present study addresses this gap in the literature by providing a detailed investigation of syntactic and higher-level discourse abilities in verbal children with…

Identifying students' interests in biology can play an important role in improving existing curricula to meet their needs. An analysis of 1,751 self-generated biological questions raised by children, adolescents, and adults yielded data regarding the different age groups' interests in biology. Research limitations and applications for teaching are…

Previous research, which typically overestimated competence, indicates that preschoolers have an unreliable or a localized understanding of the addition-subtraction inverse principle (e.g., 2 + 1 - 1 = 2). Forty-eight Taiwanese 4- to 6- year-old participants were tested with a relatively conservative measure to gauge when a reliable and general…
