![]() The researchers then introduced a novel “lesion-deficit mapping” approach to disentangle the intricate anatomical patterns of common forms of brain injury, such as stroke. Each problem presents an incomplete pattern of geometric figures and requires selection of the missing piece from a set of multiple possible choices. ![]() The test contains multiple-choice visual pattern problems of increasing difficulty. The new study, led by UCL Queen Square Institute of Neurology and National Hospital for Neurology and Neurosurgery at UCLH researchers and published in the journal Brain, investigated 227 patients who had suffered either a brain tumor or stroke to specific parts of the brain, using the Raven Advanced Progressive Matrices (APM): the best-established test of fluid intelligence. Such “lesion-deficit mapping” studies are difficult to conduct owing to the challenge of identifying and testing patients with focal brain injury.Ĭonsequently, previous studies have mainly used functional imaging (fMRI) techniques – which can be misleading. To establish which parts of the brain are necessary for a certain ability, researchers must study patients in whom that part is either missing or damaged. These skills can all be used in everyday activities – from organizing a dinner party to filling out a tax return.ĭespite its central role in human behavior, fluid intelligence remains contentious, with regard to whether it is a single or a cluster of cognitive abilities, and the nature of its relationship with the brain. It also correlates with many cognitive abilities such as memory.įluid intelligence is thought to be a key feature involved in “active thinking” – a set of complex mental processes such as those involved in abstraction, judgment, attention, strategy generation, and inhibition. It predicts educational and professional success, social mobility, health, and longevity. Fluid intelligence is involved in “active thinking,” which includes mental processes like abstraction, judgment, attention, strategy generation, and inhibition.Ī team led by University College London (UCL) and University College London Hospitals (UCLH) researchers has mapped the parts of the brain that support our ability to solve problems without prior experience – otherwise known as fluid intelligence.įluid intelligence is arguably the defining feature of human cognition. This type of intelligence is considered to be a key aspect of human cognition and is linked to a range of cognitive abilities, including memory, as well as educational and professional success, social mobility, health, and longevity. A team of researchers has identified the areas of the brain that enable us to solve problems without prior experience, also known as fluid intelligence. ![]()
