In a study of eyewitness memory, witnesses to a mock crime were asked to recall the event after being randomly assigned to one of three conditions, involving either a hypnotic memory-enhancement procedure, a "cognitive interview" procedure, or a no-treatment control procedure.

The number of correct details recalled and some initial calculations are found below. . .. . | s 10 [0 m 12 a 4 u 9 a 9 5 s s 4 3-120 4.60 Z -7.20 Grandma-8.00 sf - 5.20 s; - 5.30 3;\" - 5.70 SS. - 20.80 SS; - 21.20 38; - 26.80
