I investigated the relationship between encoding of the structural description system and binocular stereopsis. The structural description system is a component of the implicit memory system, and retains representations of possible figures. According to the previous studies, the priming effect based on it was produced only when the direction of the stimulus, which was the line drawing of the 3-dimensional object, was judged in the study phase. Because the judgment requires 3-dimensional processing, I proposed a hypothesis that the priming effect is also produced by binocular stereopsis in the study phase, and examined it by two priming experiments, in which different five undergraduates participated respectively. In the study phase, the primer was presented in binocular disparity (Experiment 1) or monocularly (Experiment 2), and the participants judged which lines were more, horizontal or vertical. In the test phase, the participants judged that the monocular stimulus was symmetrical or asymmetrical. The priming effect was produced only in Experiment 1, and was not in Experiment 2. The results supported the hypothesis, and suggest that encoding needs 3-dimensional processing in the structural description system.
