Review of the evidence suggests that  task performance  may be useful in identifying individuals with ADHD at risk for academic impairment .
However , the evidence is less compelling for identifying youth at risk for impaired social functioning or poor health outcomes .
The review also found that task performance is likely useful for predicting response to treatment with methylpheni date .
Across studies , evidence indicated that interpreting task performance in an integrated manner , such as a factor score or mean score , was more consistently useful for predicting outcomes of interest than interpreting performance from a single task .
The role that neuropsychological task performance plays in the assessment of Attention-Deficit/Hyperactivity Disorder ( ADHD ) is currently ambiguous , and findings are mixed regarding whether tasks have validity for diagnosing the disorder .
Irrespective of their validity for diagnosing ADHD , neuropsychological tasks could provide valuable information to mental health professionals if they can inform recommendations for treatment targets and modalities .
Therefore , this review sought to synthesize the available evidence related to the use of neuropsychological task performance as a tool for informing treatment planning for youth with ADHD .
Review ed studies focused on examinations of associations between task performance and academic , social , and health outcomes , as well as response to treatment .
The Unity and Diversity of Executive Functions and Their Contributions to Complex “Frontal Lobe” Tasks: A Latent Variable Analysis
This individual differences study examined the separability of three often postulated executive functions-mental set shifting ( " Shifting " ) , information updating and monitoring ( " Updating " ) , and inhibition of prepotent responses ("Inhibition")- and their roles in complex " frontal lobe " or " executive " tasks . One hundred thirty-seven college students performed a set of relatively simple experimental tasks that are considered to predominantly tap each target executive function as well as a set of frequently used executive tasks : the Wisconsin Card Sorting Test ( WCST ) , Tower of Hanoi ( TOH ) , r and om number generation ( RNG ) , operation span , and dual tasking .  Confirmatory factor analysis indicated that the three target executive functions are moderately correlated with one another , but are clearly separable . Moreover , structural equation modeling suggested that the three functions contribute differentially to performance on complex executive tasks . Specifically , WCST performance was related most strongly to Shifting , TOH to Inhibition , RNG to Inhibition and Updating , and operation span to Updating . Dual task performance was not related to any of the three target functions . These results suggest that it is important to recognize both the unity and diversity of executive functions and that latent variable analysis is a useful approach to study ing the organization and roles of executive functions
