Problem: Provide me with the data description and results of the following: Results Korin's (1974) hypothesis of a marked perceptual disturbance among heroin addicts was confirmed. Heroin addicts averaged only 6.19 correct BVRT responses and made an average of 6.17 errors across the 10 designs (Table 1). Eight correct responses and three errors are expected for a group scoring within the average range of intelligence, according to Benton's (1974) norms for Administration A. Heroin addicts scored 2 points below Benton's (1974, p. 44) normative groupmean for samples in the 15-44-year-old range having average intelligence. Given the heroin addicts' average PM performance, contrasted with the same group's performance on the BVRT, which fell in the Borderline classification (2SD below average, equivalent to the 70-79 IQ range), there are indications of a selective deficit in visual memory among heroin addicts. Heroin addicts do not differ from nonheroin drug abusers in number of errors or number of correct responses (Table 1). Qualitative analysis by types of errors indicated that the pattern of heroin addict errors is similar to the pattern of polydrug abuser errors, except that nonheroin drug users make significantly more distortion errors than heroin addicts.
