Before you throw your steak on the grill or in the oven, notice its color. While beef steaks commonly turn a bit brown or darken slightly after a few days of refrigeration -- a result of the natural process of oxidation -- light gray, purplish or green-hued steaks are unfit for cooking.

You'll recall the development of adult intelligence tests from earlier in the semester I hope. Basically, the WISC came out in 1949 as a downward extension of an adult IQ test, the Wechsler Bellevue, and was revised in 1974 (WISC R) by Wechsler. The Psychological Corporation revised it again in 1991 (WISC III), and again in 2003 (WISC IV).
