Significantly different values are shown in bold print. CD is percent correct detections; CE, percent commission errors; CE/CD, ratio of commission errors to correct detections; CD RT, the reaction time (ms) to a correct detection; CE RT, the reaction time (ms) to a commission error; A′, discriminability; and beta, response bias.
