The Seguin Form Board Test is used to assess visual discrimination and matching and eye-hand coordination. Previous analysis has shown the vactor loadings for the same scale to differ among age levels, so the test may be measuring different abilities at different age levels. Test materials consist of ten differently shaped wooden blocks and a large form board with recessed corresponding to these shapes. The child is instructed to put the shapes where they belong as fast as he/she can. Three trials are given, each with similar instructions, and Ss are instructed to go faster on each trial. Time, in seconds, and number of errors were obtained for each trial. A significant decrease in response time from Year 1 to Year 2 was found. Results indicate that cognitive-perceptual abilities are involved in Seguin performance. Sex differences were small but indicated that girls performed better than boys. Fewer errors as well as faster response time were associated with age in both years. SES differences for time and error scores were relatively small. Comprehension of the task is evident in the decrease in time scores across trials; the decrease in error scores across trials may indicate a practice effect.
