Planning (cognitive)


Cognitive planning is one of the executive functions. It encompasses the neurological processes involved in the formulation, evaluation and selection of a sequence of thoughts and actions to achieve a desired goal. Various studies utilizing a combination of neuropsychological, neuropharmacological and functional neuroimaging approaches have suggested there is a positive relationship between impaired planning ability and damage to the frontal lobe.
A specific area within the mid-dorsolateral frontal cortex located in the frontal lobe has been implicated as playing an intrinsic role in both cognitive planning and associated executive traits such as working memory.
Disruption of the neural pathways, via various mechanisms such as traumatic brain injury, or the effects of neurodegenerative diseases between this area of the frontal cortex and the basal ganglia specifically the striatum, may disrupt the processes required for normal planning function.
Individuals who were born with very low birth weight and extremely low birth weight are at greater risk of various cognitive deficits including planning ability.

Neuropsychological tests

There are a variety of neuropsychological tests which can be used to measure variance of planning ability between the subject and controls.
In test, participants with damage to the right anterior, and left or right posterior areas of the frontal lobes showed no impairment. The results implicating the left anterior frontal lobes involvement in solving the TOL were supported in concomitant neuroimaging studies which also showed a reduction in regional cerebral blood flow to the left pre-frontal lobe. For the number of moves, a significant negative correlation was observed for the left prefrontal area, i.e. subjects that took more time planning their moves showed greater activation in the left prefrontal area.
