However, previous research suggests that tasks of one category can be transferred into the…

The study evaluated speed as a factor in Wechsler Intelligence Scale for Children-Revised performance with 66 high scoring and 36 average scoring children (ages 3-15 years). Results cast doubt on the utility of speed bonuses in tests of general intelligence with gifted children. (Author/DB)

Since the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was published in 1991, it has been reported that fewer students are qualifying for gifted programs that use the WISC-III as a criterion measure.

This study evaluated the reliability and validity of the Blind Learning Aptitude Test with 193 Indian children (ages 8-15) with visual impairments and the relationship between time to complete and test performance. Results indicated satisfactory validity and reliability and completion rates of 30 to 133 minutes. (DB)

A study was conducted at Cuyahoga Community College to test the relationship between student scores on timed and untimed reading comprehension and vocabulary tests, and to investigate the relationship between those scores and intelligence. The study sample included 72 students enrolled in classes at developmental, freshman, and sophomore levels.…
