The protocol and design of a randomised controlled study on training of attention within the first year after acquired brain injury
Attention Process Training (APT), a hierarchical, multilevel treatment program, was designed to remediate attention deficits in brain-injured persons. The program incorporates current theories in the experimental attention literature. Four brain-injured subjects, varying widely in both etiology of injury and time post onset, underwent intensive cognitive remediation including 5 to 10 weeks of specific attention training. Results are displayed using a single subject multiple baseline across behaviors design. All four subjects demonstrated significant gains in attention following the initiation of attention training. Remediation of another cognitive function (visual processing) was not associated with alterations in attention behavior. The merits of a process-specific approach to cognitive rehabilitation are discussed.
