Figure 2. Examples of Discretionary pattern trajectories over time.

Infant ‘A’ scores low on the Discretionary pattern at 6 months (low intercept) and continues to score low on the Discretionary pattern (level trajectory). Infant ‘B’ scores high on the Discretionary pattern at 6 months (high intercept) and continues with a high score (level trajectory). Infant ‘C’ could be the subject of interventions that target children with high scores and aim to reduce scores in the Discretionary trajectory.
