Global and Domain-Specific Changes in Cognition throughout Adulthood
Peer reviewed Peer reviewed
Direct linkDirect link
Tucker-Drob, Elliot M. – Developmental Psychology, 2011
Normative adult age-related decrements are well documented for many diverse forms of effortful cognitive processing. However, it is currently unclear whether each of these decrements reflects a distinct and independent developmental phenomenon, or, in part, a more global phenomenon. A number of studies have recently been published that show…

Molenaar, Peter C. M.; Sinclair, Katerina O.; Rovine, Michael J.; Ram, Nilam; Corneal, Sherry E. – Developmental Psychology, 2009
Individuals change over time, often in complex ways. Generally, studies of change over time have combined individuals into groups for analysis, which is inappropriate in most, if not all, studies of development. The authors explain how to identify appropriate levels of analysis (individual vs. group) and demonstrate how to estimate changes in…

Temporal Patterns of Variable Relationships in Person-Oriented Research: Longitudinal Models of Configural Frequency Analysis
Peer reviewed Peer reviewed

von Eye, Alexander; Mun, Eun Young; Bogat, G. Anne – Developmental Psychology, 2008
This article reviews the premises of configural frequency analysis (CFA), including methods of choosing significance tests and base models, as well as protecting [alpha], and discusses why CFA is a useful approach when conducting longitudinal person-oriented research. CFA operates at the manifest variable level. Longitudinal CFA seeks to identify…

Developmental Changes in Time Estimation: Comparing Childhood and Old Age.
Peer reviewed Peer reviewed
McCormack, Teresa; Brown, Gordon D. A.; Maylor, Elizabeth A.; Darby, Richard J.; Green, Dina – Developmental Psychology, 1999
Examined developmental changes in time estimation among 5- to 99-year olds. Found that older adults and young children performed at lower levels than young adults; identified qualitative differences in error patterns of older adults and children. Proposed model of temporal generalization and bisection assuming developmental changes in noisiness of…
