title: Role of working memory, inhibition, and fluid intelligence in the performance of the Tower of London task.
abstract: We investigated the relationship between verbal and visuo-spatial measures of working memory, inhibition, fluid intelligence and the performance on the Tower of London (ToL) task in a large sample of 830 healthy participants aged between 18 and 71 years. We found that fluid intelligence and visuo-spatial working memory accounted for a significant variance in the ToL task, while performances on verbal working memory and on the Stroop Test were not predictive for performance on the ToL. The present results confirm that fluid intelligence has a fundamental role on planning tests, but also show that visuo-spatial working memory plays a crucial role in ToL performance.
