Accuracy Reaction Time Longitudinal CDI Items Reliability

How reliable is windowed accuracy as an individual-difference measure — and how does that depend on the analysis window? This explorer computes split-half reliability (children’s trial sets split randomly in half, half-means correlated across children, Spearman-Brown corrected) for a grid of analysis windows, in your browser.

The heatmap sweeps window start (−500 to 1500 ms) and end (1000 to 4000 ms); your window is marked ×.

Cells with too few children (< 8 usable) are blank. The × marks the grid cell nearest your window.
