Cognitive Control at Age 3: Evaluating Executive Functions in an Equitable Montessori Preschool

Studies in cognitive neuroscience have shown that education practices can affect the development of executive functions (EF) in young children, although there is very little evidence on young preschool children. The present study aims to provide support for this endeavor, and consists of a quasi-experimental design with one-group pre-test/post-test measures of cognitive control at age 3 in an urban public Montessori preschool. Three-year-olds (N = 23) in an authentic Montessori public preschool in Washington DC improved significantly on core EF measures (inhibitory control and cognitive flexibility) validated by the NIH Toolbox Early Childhood Cognition Battery, and the data revealed large effect sizes. Comparisons against NIH published norms revealed no selection bias. Performance on EF measures did not correlate with age but did correlate with amount of time between testing sessions, suggesting the possibility that experience, more than age, could have contributed to cognitive control growth. A controlled comparison between mixed-age and single-age classes revealed no differences in these EFs, raising the possibility that aspects of the environment other than the age composition are likely to contribute to growth. We propose that a potential contributor to EF growth is Montessori education, and more specifically, that this growth might be found in the design of interaction of the child with the environment. In particular, we discuss the design element called control of error, and consider why this element might be related to cognitive abilities such as inhibitory control. In current national discussions on the importance of equitable early childhood education, the synthesis of findings from neurocognitive studies has implications for children's academic and life success

At-risk elementary school children with one year of classroom music instruction are better at keeping a beat

Temporal processing underlies both music and language skills. There is increasing evidence that rhythm abilities track with reading performance and that language disorders such as dyslexia are associated with poor rhythm abilities. However, little is known about how basic time-keeping skills can be shaped by musical training, particularly during critical literacy development years. This study was carried out in collaboration with Harmony Project, a non-profit organization providing free music education to children in the gang reduction zones of Los Angeles. Our findings reveal that elementary school children with just one year of classroom music instruction perform more accurately in a basic finger-tapping task than their untrained peers, providing important evidence that fundamental time-keeping skills may be strengthened by short-term music training. This sets the stage for further examination of how music programs may be used to support the development of basic skills underlying learning and literacy, particularly in at-risk populations which may benefit the most
