Longitudinal panel studies are widely used in developmental science to address important research questions on human development across the lifespan. These studies, however, are often challenging to implement. They can be costly, time-consuming, and vulnerable to test--retest effects or high attrition over time. Planned missingness designs (PMDs),…

Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

Configural frequency analysis and log-linear modeling are presented as person-centered analytic approaches for the analysis of categorical or categorized data in multi-way contingency tables. Person-centered developmental psychology, based on the holistic interactionistic perspective of the Stockholm working group around David Magnusson and Lars…

Inherent in applied developmental sciences is the threat to validity and generalizability due to missing data as a result of participant drop-out. The current paper provides an overview of how attrition should be reported, which tests can examine the potential of bias due to attrition (e.g., t-tests, logistic regression, Little's MCAR test,…

Research on school bullying has its roots in the field of developmental and educational psychology, and appeals to the need for a theoretical and methodological widening in order to grasp its ambiguity and complexity. The article draws on ethnographic fieldwork in which 144 pupils and seven teachers participated from seven school classes in three…

While developmental discourses have been heavily critiqued in relation to education systems, less attention has been paid to how these impact the data collection process in classroom research. This article utilises Foucault's concept of regime of truth to highlight the pervasiveness of developmental discourses when conducting research in primary…

Existing data sets can be an efficient, powerful, and readily available resource for addressing questions about developmental science. Many of the available databases contain hundreds of variables of interest to developmental psychologists, track participants longitudinally, and have representative samples. In this article, the authors discuss the…

The process of building a culture of evidence involves using data to understand where students are experiencing problems, designing strategies for remedying those problems, implementing them, and then evaluating the effectiveness of those implemented strategies. This case study is about two programs that were implemented within the last two years…

This paper problematizes contemporary cultural understandings of autism. We make use of the developmental psychology concepts of "Theory of Mind" and "mindblindness" to uncover the meaning of autism as expressed in these concepts. Our concern is that autism is depicted as a puzzle and that this depiction governs not only the way Western culture…

Beliefs about the nature of knowledge and knowing have been investigated extensively in educational and developmental psychology research. Hofer's framework on personal epistemology is adopted in the present study for assessing Lebanese university students' epistemologies of science. Participants were 213 students in their first year of…

Children who enter the child welfare system at a young age are at risk for a myriad of developmental, physical, and mental health problems. The risks faced by these vulnerable young children may be exacerbated by placement disruptions during foster care. This study utilizes administrative data from Illinois to explore the potential of child care…

More than half of all online American adolescents and emerging adults have created personal profiles for social networking on the Internet. Does homophily in their offline friendships extend online? Drawing mainly on research of face-to-face friendship, we collected data from the public spaces, called "walls," of 129 young Americans ages 16 to 19…

The current study tested whether the purely amodal cue of contingency elicits orientation following behavior in 8-month-old infants. We presented 8-month-old infants with automated objects without human features that did or did not react contingently to the infants' fixations recorded by an eye tracker. We found that an object's occasional…

Longitudinal data analysis has long played a significant role in empirical research within the developmental sciences. The past decade has given rise to a host of new and exciting analytic methods for studying between-person differences in within-person change. These methods are broadly organized under the term "growth curve models." The…

Intergenerational service-learning between college students and older adults is a commonly used in educational gerontology. Service-learning is believed to enhance student learning through an equivalent focus on service and learning, reflection, and linking course content with the service experience. This article describes a comentoring project…
