In this paper, we describe a novel approach to the study of problem solving involving the detailed analysis of natural scanning eye movements during the "one-touch" Tower-of-London (TOL) task. We showed subjects a series of pictures depicting two arrangements of colored balls in pockets within the upper and lower halves of a computer display. The task was to plan (but not to execute) the shorte...

This study triangulates executive planning and visuo-spatial reasoning in the context of the Tower of London (TOL) task by using a variety of methodological approaches. These approaches include functional magnetic resonance imaging (fMRI), functional connectivity analysis, individual difference analysis, and computational modeling. A graded fMRI paradigm compared the brain activation during the...

BACKGROUND System redesign is described in one primary care trust (PCT)/clinical commissioning group (CCG) resulting in improved cardiovascular disease (CVD) management. AIM To evaluate CVD managed practice networks in one entire local health economy using practice networks, compared with PCTs in London, England, and local PCTs. DESIGN AND SETTING Observational study of 34 general practices...

The Royal Menagerie of England was established at the Tower of London in the 13th Century and served as a home of exotic animals until it was closed on behalf of the Duke of Wellington in 1835. Two well-preserved lion skulls recovered from the moat of the Tower of London were recently radiocarbon-dated to AD 1280-1385 and AD 1420-1480, making them the earliest con rmed lion remains in the Brit...

Despite widespread use the cognitive demands of the five-disc Tower of London (TOL) are unknown. Research suggests that conflict moves (those that are essential to the solution but do not place a disc in its final position) are a key aspect of performance. These were examined in three studies via a verification paradigm, in which normal participants were asked to decide whether a demonstrated m...
