Note: M = Mean; SD = Standard Deviation. Test measures that are starred in this table were excluded from the factor analyses due to normative samples that were separately recruited or inadequate in size (i.e., BDAE Complex Ideational Material, PIAT spelling, and PIAT reading comprehension), or to avoid introducing gender differences based on physiology rather than cognition (i.e., Grip Strength Test and Finger Tapping Test).
