Methods for identifying dyslexia in adults vary widely between studies. Researchers have to decide how many tests to use, which tests are considered to be the most reliable, and how to determine cut-off scores.

A total of 32 college freshmen participated, most of whom were poor and had below average academic averages as measured by high school grade point average.

Piagetian levels of 126 volunteers (60 males and 66 females) were measured using the Burney Logical Reasoning Test. Findings demonstrated that the six predictor variables succeeded in explaining 58% (pooled male/female sample), 53% (female sample), and 59% (male sample) of the variance in Piagetian cognitive levels. In addition, since prediction…
