Abstract

The Tower of London task (TOL) has been widely used to assess the ability to plan. We used H(2)O(15)-positron emission tomography to isolate some of the cognitive components of the task. Ten male volunteers were scanned twice in each of six conditions. In two conditions (plan) the subjects had to plan the best solution to TOL problems. In two other conditions (plan-control) the subjects were required to generate four moves without being constrained by a goal. In plan and plan-control tasks the subjects either planned the moves and then executed them (MOVE conditions) or imagined the necessary moves (IMAGINE conditions). The plan and plan-control tasks were matched for the working memory load and "initial thinking time". A visuomotor control task and rest served as baseline conditions. Performance on the plan tasks, in contrast to the baseline conditions, was associated with activation in the dorsal prefrontal cortex, premotor and parietal cortex, and cerebellum. Performance of the plan-control tasks was associated with activation of the same areas. Contrasting the plan with the plan-control tasks revealed no residual activation in the prefrontal cortex. These data show that the activity of the dorsolateral prefrontal cortex on the TOL can be accounted for by the components of generating, selecting and/or remembering mental moves. The task of relating the moves to the goal involves a comparison with a representation of the goal in posterior association areas. We did not find e…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
