Impulsivity and risk-taking behavior in focal frontal lobe lesions.
Frontal lobe dysfunction may underlie excessively impulsive and risky behavior observed in a range of neurological disorders. We devised a gambling task to examine these behavior tendencies in a sample of patients who had sustained focal damage to the frontal lobes or nonfrontal cortical regions as well as in a matched sample of healthy control subjects. The main objectives of the study were: (...
متن کاملFrontal lobe and motivation of learned behavior.
Dorsal prefrontal lesions in dogs elicit hyperreactivity in instrumental discrimination and perseveration in trained serial action pattern. Lateral premotor injury causes hyporeactivity in instrumental discrimination and prolongation of activity in the trained serial action pattern. When the dorsal prefrontal area was injured together with the premotor region the result was again hyporeactivity...
متن کاملVerbal and design fluency in patients with frontal lobe lesions.
The ability to generate items belonging to categories in verbal fluency tasks has been attributed to frontal cortex. Nonverbal fluency (e.g., design fluency) has been assessed separately and found to rely on the right hemisphere or right frontal cortex. The current study assessed both verbal and nonverbal fluency in a single group of patients with focal, frontal lobe lesions and age- and educat...
متن کاملExecutive function and fluid intelligence after frontal lobe lesions
Many tests of specific 'executive functions' show deficits after frontal lobe lesions. These deficits appear on a background of reduced fluid intelligence, best measured with tests of novel problem solving. For a range of specific executive tests, we ask how far frontal deficits can be explained by a general fluid intelligence loss. For some widely used tests, e.g. Wisconsin Card Sorting, we fi...
