Modeling Individual Differences in Brain Development

Individual differences in human brain development

This article discusses recent scientific advances in the study of individual differences in human brain development. Focusing on structural neuroimaging measures of brain morphology and tissue properties, two kinds of variability are related and explored: differences across individuals of the same age and differences across age as a result of development. A recent multidimensional modeling stud...

Individual differences and development of speech act production

This  study  examined  the  effects  of  individual  difference  (ID)  factors  on  changing  pragmatic abilities  among  L2  learners  of  English.  Participants  were  48  Japanese  EFL  students  in  an English-medium  university  in  Japan.  They  completed  a  pragmatic  speaking  test  (k=12)  that assessed  their  ability  to  produce  two  speech  acts:  requests  and  opinions,  in  hi...

Modeling Variability in Individual Development: Differences of degree or kind?

The proper use of statistical models for analyzing individual change over time is critical for the progress of developmental science. Latent curve models, hierarchical linear growth models, group-based trajectory models, and growth mixture models constitute increasingly important tools for longitudinal data analysis. To facilitate their understanding and use, this paper clarifies similarities a...

Modeling individual differences in cognition.

Many evaluations of cognitive models rely on data that have been averaged or aggregated across all experimental subjects, and so fail to consider the possibility of important individual differences between subjects. Other evaluations are done at the single-subject level, and so fail to benefit from the reduction of noise that data averaging or aggregation potentially provides. To overcome these...
