Data and code for: Emergent blink rate in early childhood is associated with neural origins of executive function

Data and analysis code for the study "Emergent blink rate in early childhood is associated with neural origins of executive function" (Kuwamizu, Yamamoto, Otani & Moriguchi). The deposit contains a participant-level dataset of 113 preschool children — spontaneous eye-blink rate, Dimensional Change Card Sort performance, and task-evoked prefrontal oxy-Hb responses measured with fNIRS — together with the R pipeline that reproduces the reported statistics and exports the figure source data, and a GraphPad Prism file holding the per-participant oxy-Hb waveforms plotted in Fig. 3a. See README.md for the variable dictionary and instructions.
