These were presented in random order, to prevent any practise effects from systematically impacting our data across the critical experimental conditions.
However practise effects may result in artificial improvement in performance over repeated cognitive assessments in longitudinal studies.
In normal adults who did four CogState sessions within 3 h, practise effects were also observed between the first and second session with minimal effects observed later [ 30].

In a study to examine practise effects when CogState is used repeatedly, children who were administered four CogState trials within 2 h, test retest reliabilities between the first and second sessions ranged from 0.58 to 0.73 for tests similar to what we administered in the present study [ 29].
