Research Design and Analysis ,[object Object],An error was scored when a test subject performed an incorrect action Only a prompt was recorded if a test subject asked for help before taking an incorrect action Accuracy Number of verbal or gestural prompts per step, maximum of three prompts per step Independence Measured by: Variable

Results *Significant difference p < .032 SD = 2.56 SD = 1.19 (Total help prompts needed–lower scores are better) X = 2.40* X = 1.05* Independence p <.006 SD = 2.05 SD = 0.83 (Average number of errors on the two tasks-lower scores are better) X = 2.25* X = 0.75* Errors per task One tailed significance No visual assistant Visual assistant Dependent measure
