Abstract: | Instructions for the Matrix Reasoning subtest of the WAIS-III do not communicate to examinees that the subtest is untimed. The present study examined what percentage of participants (34 women, 26 men, M age = 20.1; 55 Caucasian, 3 African American, 2 Hispanic) made the assumption that Matrix Reasoning was timed, and its effect on examinees' scores. 55% of participants receiving standard instructions retrospectively reported assuming the subtest was timed, and those who did not assume Matrix Reasoning was timed scored significantly higher than participants who did. Participants receiving additional instructions that clarified the untimed nature of Matrix Reasoning scored significantly higher than those receiving standard instructions who believed the subtest was timed. |
