These three were omissions of part of a letter, perseverations, and reversals or letters. Any described characteristic had to appear at least four times on the sample form to be counted as part of the individual's writing habit. No hand printing samples were included. Data were gathered on the basis of race, sex, age, and educational level, and whether or not any or all of the three writing defects occurred. Results showed significant differences between males and females, with males showing twice as many defects as females. However, significant differences were not found between blacks and white populations nor between dropouts or those completing high school. Overall, writing defects occurred in 33.5 percent of the participants. The higher percentage of writing defects in the males is consistent with other research reporting on the relationship between illegal acts and learning disabilities and on the preponderance of males among people with learning disabilities.
