Make Me Adaptive: The Case of Inhibition

Inhibition is one of the main executive function showing an age-related decline. It is often hypothesized as a major factor in cognitive ageing, and as a result a number of interventions aimed at inhibition in aging has been proposed. Adaptive nature of interventions usually results in its greater efficacy. Still, adaptive trainings are typically found in working memory domain, and less for other cognitive functions. This study was aimed to design an adaptive inhibition task to be used in cognitive training for older adults. A total of N=90 older adults (60 and older) completed the picture-word inhibition task – a main inhibition measure, in which objects are shown with either a congruent or an incongruent word inscribed. The task is to ignore the word and react to the object. Three versions of task, differing in the ratio of congruent and non-congruent stimuli (75:25 ; 50:50 ; 25:75) were used, together with a Simon task, n-back task, memory updating numerical task and Raven’s Progressive Matrices. The accuracy and speed of response were used as dependent variables at each task level. The results show that picture-word task can be used as an adaptive inhibition task. The MTMM correlation analysis shows good convergent validity.
