title: Hand Test characteristics of marijuana-experienced and multiple-drug-using college students.
abstract: Three matched groups of 30 college student (17 males, 13 females) categorized as marijuana users, multiple-drug users, and complete abstainers were compared across 24 Hand Test scores. Both drug-using groups were characterized by significantly lower scores on Acquisition, Active, and Environmental responses. Results were interpreted as supporting the amotivational hypothesis that drug-users display a lessened interest in environmental accomplishment. The marijuana group also proved to be slightly higher on the Exhibition score.
