The Analytic Techniques and Technology Core (AT&T) is a reconfigured core designed toprovide advanced data analytic services to Center investigators. It complements the functions ofthe Participant Recruitment and Management and Digital and Electrical Engineering Cores byconcentrating on techniques and technologies for data analysis including the application ofadvanced statistical techniques. The Core assists Center investigators by (1) planning andconducting advanced statistical analyses using cutting-edge methods including mixedmodeling, structural equation modeling, and other techniques for the analysis of multivariate,longitudinal data; (2) training Center investigators in innovative advanced analytic techniquessuch as graphical analysis and data warehousing; and (3) helping with grant proposalpreparation and final report preparation including write-up of methods, procedures, and resultssections. The AT&T Core provides Center investigators with the ability to use new methods, forthe detection of individual and group differences in patterns of growth and change, enablingCenter investigators to move forward on current research programs. The Core offers strategic,targeted, high-level services that are not provided elsewhere. The AT&T Core brings Centerresearchers together for workshops and tutorials on new methods for the analysis of change andnew technologies for data aggregation and analysis that serve as 'incubators' for crossdisciplinaryinitiatives. A key new initiative for the AT&T Core is developing Center-levelcollaborations to compile a data warehouse of measures of language and cognitive developmentmaking it possible for Center investigators to use new techniques for aggregate analysis andgraphical analysis to explore commonalties among their projects. A key question will be toexamine the relationship between cognition, grammatical development and vocabularydevelopment across the life span, with an aim to detecting, e.g., early life predictors or readingimpairments in school-aged children or predictors of late life cognitive decline.
