The paper contends that advances in imaging technology, made over the past five decades, have enabled the recognition of many of the cognitive and behavioural correlates of organic brain impairments. As a result, a new range of psychological tools has been developed that have proven effective as diagnostic indicators of lesions or other malfunctions. The paper concentrates on the frontal lobe regions. It reviews the types of damage that occur and the behavioural patterns and problems associated with them. The paper then examines and reviews measures that have been formulated to assess the nature and extent of that frontal lobe damage.

From the Paper:

"The idea of cerebral localisation of psychological functions has existed in various forms since Gall (1935), but only recently have researchers been able to locate specific psychological processes to particular brain structures with any confidence; and studies of malfunction have been found to hold critical value here in identifying normal functioning. Kolb and Whishaw (2003) offer five discrete categories of psychological abnormality associated with frontal lobe lesions: (1) disturbances of motor functions; (2) loss of divergent thinking; (3) impaired response inhibition and inflexible behaviour; (4) poor temporal memory, and (5) impaired social and sexual behaviour imaging. Evidence, however, suggests a degree of overlap and interaction between categories. For the present analysis, the 'cognitive' categories, (2) and (4), will be discussed together, as will the categories relating to social behaviour and inhibition: (3) and (5)."
