Section Text: 
The CPT 3™ is a task-based computerized assessment of attention disorders and neurological functioning. Results from the CPT 3™ can clarify the nature of attention deficits, quickly identifying problems with impulsiveness, activation/arousal, or vigilance, for example. Administered in educational, psychiatric, medical, and correctional settings, the CPT 3™ can be used to screen for or diagnose ADHD, monitor treatment, test the effects of medication, or determine optimal drug dosage. New to Version 5 are two very convenient options: minimizing false positives and minimizing false negatives. The former option is useful when you want only very strong evidence of ADHD in order to avoid unnecessary follow-up evaluation. The latter is helpful when you want to identify as many potential attention problems as possible. Appropriate for individuals aged 6 years and up, the CPT 3™ presents target letters on a computer screen. The examinee's task is to press the space bar or click the mouse whenever any letter other than "X" appears. Letters are displayed for 250 milliseconds, at 1-, 2-, and 4-second intervals. Administration time is 14 minutes.

Sport-Related Concussion Specific: Advantage: The Conners CPT 3™ is a standard in the assessment of sustained visual attention and is used widely for other neurological conditions, notably ADHD. It includes a variety of measures to assess accuracy, target detection, impulsivity, and discrimination of targets from non-targets. Limitations: The measure is not widely used in subacute concussion and would more often be used in a comprehensive neuropsychological assessment.
Age Range: 8-adult
