The current study investigates the factor structure of the Conners' Continuous Performance Test-II (CPT-II) in four pediatric samples of participants: (a) patients with traumatic brain injury, (b) healthy controls, (c) patients with various clinical diagnoses, and (d) all of the previously mentioned subjects combined. Confirmatory factor analyses (CFA) were used to investigate a one-, three- and four-factor model fit of the data. None of the models examined were an adequate fit for the data; however, it appears that the four-factor model seemed to be the best fitting of the models examined. Failure to find reasonably adequate fit precluded further analyses.

Mathematics anxiety is a negative affective reaction to situations involving mathematical thought and is commonly believed to reduce cognitive functioning by impairing the efficient use of working memory resources. The conventional theory describes that the processing disadvantage associated with high levels of math anxiety increasingly impairs performance as working memory demands increase in a math task. Despite this convention, recent reports demonstrate that the high math anxious disadvantage can be measured in tasks that are relatively free of working memory assistance (Maloney, Ansari, & Fugelang, 2011; Maloney, Risko, Ansari, & Fugelsang, 2010). The present study examines these relatively low level …
