Abstract: Progress in understanding cognitive developmental change mechanisms requires methods that yield detailed data about particular changes. The microgenetic method is an approach that can yield such data. It involves (a) observations of individual children throughout the period of the change, (b) a high density of observations relative to the rate of change within that period, and (c) intensive trial-by-trial analyses intended to infer the processes that gave rise to the change. This approach can illuminate both qualitative and quantitative aspects of change, indicate the conditions under which changes occur, and yield otherwise unobtainable information about short-lived transition strategies. The cost in time and effort of such studies is often high, but the value of the information about change can more than justify the cost.
TL;DR: The microgenetic method has been advocated by developmentalists as a promising tool in the study of change Despite convergence of findings across investigators and diverse domains, several fundamental questions need to be answered as discussed by the authors, such as: (a) Is the potential for change specific to periods of developmental transition? (b) Is change domain-general or domain-specific? (c) Why and how does change occur?
Abstract: The microgenetic method has been advocated by developmentalists as a promising tool in the study of change Despite convergence of findings across investigators and diverse domains, however, several fundamental questions need to be answered (a) Is the potential for change specific to periods of developmental transition? (b) Is change domain-general or domain-specific? (c) Why and how does change occur? Answers to these questions bear on the extent to which microgenetic study of change can be interpreted as providing insight into the natural change process
TL;DR: This paper examined how children learn to use memory strategies in a microgenetic investigation of learning and metacognition and found evidence of a causal role of training and meta-awareness that mediated the use of sorting and higher recall.

TL;DR: A microgenetic research design with a multiple case study method and a combination of quantitative and qualitative analyses was used to investigate interdyad differences in real-time dynamics and developmental change processes in mother-infant face-to-face communication over the first 3 months of life.
Abstract: A microgenetic research design with a multiple case study method and a combination of quantitative and qualitative analyses was used to investigate interdyad differences in real-time dynamics and developmental change processes in mother-infant face-to-face communication over the first 3 months of life. Weekly observations of 24 mother-infant dyads with analyses performed dyad by dyad showed that most dyads go through 2 qualitatively different developmental phases of early face-to-face communication: After a phase of mutual attentiveness, mutual engagement begins in Weeks 7-8, with infant smiling and cooing bidirectionally linked with maternal mirroring. This gives rise to sequences of positive feedback that, by the 3rd month, dynamically stabilizes into innovative play routines. However, when there is a lack of bidirectional positive feedback between infant and maternal behaviors, and a lack of permeability of the early communicative patterns to incorporate innovations, the development of the mutual engagement phase is compromised. The findings contribute both to theories of relationship change processes and to clinical work with at-risk mother-infant interactions.
