For close to 20 years, clinicians and researchers have been developing and assessing technological interventions for individuals with either acquired impairments or developmental disorders. This paper offers a comprehensive review of literature in that field, which we refer to collectively as assistive technology for cognition (ATC). ATC interventions address a range of functional activities requiring cognitive skills as diverse as complex attention, executive reasoning, prospective memory, self-monitoring for either the enhancement or inhibition of specific behaviours and sequential processing. ATC interventions have also been developed to address the needs of individuals with information processing impairments that may affect visual, auditory and language ability, or the understanding of social cues. The literature reviewed indicates that ATC interventions can increase the efficiency of traditional rehabilitation practices by enhancing a person's ability to engage in therapeutic tasks independently and by broadening the range of contexts in which those tasks can be exercised. More importantly, for many types of impairments, ATC interventions represent entirely new methods of treatment that can reinforce a person's residual intrinsic abilities, provide alternative means by which activities can be completed or provide extrinsic supports so that functional activities can be performed that might otherwise not be possible. Although the major focus of research in this field will continue to be the development of new ATC interventions, over the coming years it will also be critical for researchers, clinicians, and developers to examine the multi-system factors that affect usability over time, generalisability across home and community settings, and the impact of sustained, patterned technological interventions on recovery of function.
