Longitudinal Explorer

Several Peekbank datasets tested the same children repeatedly. Each point is one test session (administration); thin lines connect sessions from the same child, showing individual developmental trajectories in recognition accuracy and speed.

The black line is a pooled linear fit (in log age when the log axis is on); per-child lines are the raw trajectories.

First-to-last-session change per child; the solid line marks the median.
