The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...

Computerized neurocognitive assessment tools (NCATs) have become a common way to assess postconcussion symptoms. As there is increasing research directly comparing multiple NCATs to each other, it is important to consider the impact that order of test administration may have on the integrity of the results. This study investigates the impact of administration order in a study of four different NCATs; Automated Neuropsychological Assessment Metrics (ANAM4), CNS Vital Signs (CNS-VS), CogState, and Immediate Post-Concussion Assessment and Cognitive Test (ImPACT)...
