Background:
Home-based computerised cognitive training (CCT) is ineffective at enhancing global cognition, a key marker of cognitive ageing.
Objectives:
To test the effectiveness of supervised, group-based, multidomain CCT on global cognition in older adults and to characterise the dose-response relationship during and after training.
Design:
A randomised, double-blind, longitudinal, active-controlled trial.
Setting:
Community-based training centre in Sydney, Australia Participants: Eighty nondemented community-dwelling older adults (mean age = 72.1, 68.8% females) with multiple dementia risk factors but no major neuropsychiatric or sensory disorder. Of the 80 participants admitted to the study, 65 completed post-training assessment and 55 were followed up one year after training cessation.
Interventions:
Thirty-six group-based sessions over three months of either CCT targeting memory, speed, attention, language and reasoning tasks, or active control training comprising audiovisual educational exercises.
Measurements:
Primary outcome was change from baseline in global cognition as defined by a composite score of memory, speed and executive function. Secondary outcome was 15-month change in Bayer Activities of Daily Living from baseline to one year post-training.
Results:
Intention-to-treat analyses revealed significant effects on global cognition in the cognitive training group compared to active control after three weeks of training (ES = 0.33, P=.039) that increased after 3 months of training (ES = 0.49, P=.003) and persisted three months after training cessation (ES = 0.30, P=0.023). Significant and durable improvements were also noted in memory and processing speed. Dose-response characteristics differed among cognitive domains. Training effects waned gradually but residual gains were noted twelve months post-training. No significant effects on activities of daily living were noted and there were no adverse effects.
Conclusions:
In older adults with multiple dementia risk factors, group-based CCT is a safe and effective intervention for enhancing overall cognition, memory and processing speed. Dose-response relationships vary for each cognitive domain, vital information for clinical and community implementation and further trial design.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
