Three experiments were performed to test the hypothesis that induced lateral eye-movements would differentially affect performance on creativity, spatial relations, and absrraction tasks Eye-movements were induced by having Ss take tests while wearing raped goggles Partial confirmation of the hypothesis was obtained for male Ss only. In one study induced left-looking enhanced performance on a creativity test and in another, on a spatial relations task. Bakan (1969) has sought to explain the tendency of Ss to exhibit conjugate lateral eye-movements in responding to questions requiring mental efforc as due to differential activation of the cerebral hemispheres. Questions eliciting accivicy in the right hemisphere lead to left conjugate lateral eye-movements and those eliciting left hemisphere activity, right eye-movemencs. Kocel, Galin, Omstein, and Merrin (1972) found Ss tend to exhibit more right eye-movements to verbal and arithmetic questions and more left movements to spatial questions. Harnad (1972) reported a tendency for creative mathematicians to exhibit more left eye-movements than less creative mathematicians.Artificially induced eye-movements might be expected to improve performance on casks dependent upon the hemisphere activaced by the induced eyemovement. Creativity and spacial relations tasks should be facilitated by induced left eye-movements and intellectual tasks by induced right eye-movements. This paper reports t h e e experiments designed to test this hypothesis. Direction of gaze was manipulated by asking Ss to take tests while wearing safety goggles taped so as to force them to look left or to look right. Tape was placed over the left half of each lens to induce right-looking and over the right half of each to induce left-looking.In Exp. 1, 24 males in the left-looking group and 29 in the right-looking group took the Remote Associates Test (Mednick & Mednick, 1967), a test of creativity, and the abscraction subtesc of the Shipley-Hartford Intelligence Test. Left-lookers scored significantly higher on the Remote Associates Test than right-lookers ( t = 2.39, p < ,025) but insignificantly lower on the abstraction subtest. Left-lookers obtained scores of 14.71 (SD = 4.62) on the Remote Associates Test and 16.63 (SD = 1.86) on the abstraction subtest while rightlookers obtained scores of 12.28 (SD = 4.81) and 16.83 (SD = 1.91) respeccively.In Exp. 2, new groups of 22 males in the left-looking group and 26 in the right-looking group took the Remote Associates Test, the abstraction subtest, a

Seventy-two normal adult male subjects wrote TAT stories under baseline and either placebo- or marijuana-ingestion conditions. Marijuana subjects received 20 mg. doses of delta-9 tetrahydrocannabinol. The stories were keypunched and content analyzed with the Regressive Imagery Dictionary, which yields a score for primary process content. Results indicate that marijuana, relative to placebo, caused subjects to write stories with a higher proportion of primary process content than they had included in baseline stories.

Patients in token-economy programs are generally unable to reinforce each other's behavior with tokens and social interaction among patients is usually minimal. In this study, all patients on a token economy ward of a state hospital were given a daily allowance of special transferable tokens in addition to whatever other tokens they earned. Transferable tokens could be spent by any patient except the one to whom they were issued. Both the frequency of social interaction and the number of different patients interacted with increased significantly.
