Confidence Intervals are based on the Overall Average SEMs. Values reported in the SEM column are based on the examinee’s age. The GAI is an optional composite summary score that is less sensitive to the influence of working memory and processing speed. Because working memory and processing speed are vital to a comprehensive evaluation of cognitive ability, it should be noted that the GAI does not have the breadth of construct coverage as the FSIQ.
Good effort, appeared comfortable, on processing speed tasks made no errors, but completed relatively fewer items. systematic, organized approach on non- verbal tasks. Results can be considered valid.
