Several investigations reported the effects of the instruction on the acquisition process of the eyelid conditioning. Previous verbal instruction required to keep subject's attention to CS (light), eye's reaction or other parts of subject's body. Both the facilitatory and inhibitory instruction related deeply to the concentration and the dispersion of subject's attention. Then, the purpose of the present experiment was to investigate the effects of the position of subject's visual attention on the acquisition process of human eyelid conditioning. The subjects were 30 undergraduate students, they were placed at random into one (N=10) of three groups. The instruction to subjects of the experimental group 1 (Exp. G. 1) included "…… keep and watch the CS presented position as continuously as possible you can. The experimental group 2 (Exp.G.2) was instructed to"…… keep and watch the position of the white paper (5×5cm), which was set aside in 15cm distant from the CS-position. And subjects of the control group (Cont. G.) was instructed "…… relax and see the CS-presented position. The design of the experiment were as follows ; Each subject received the light (CS, 550 msec.) and the air-puff (UCS, 30msec.). CS was overlapped at 30 msec, in the last of UCS, and the intertrial intervals were 10, 15 and 20 msec.. Sixty conditioning trials were administered to the subject, 20 at each of three intertrial intervals. The pressure of the air puff (UCS) was 2.25 g/cm^2, and UCS was presented the cornea of the left eye. The eyelid response were measured the lid of the same eye. The main findings were as follows ; On the acquisition of the conditioned response (CR), the factor analysis of variance were performed with three groups. The analysis was based on percentage of CRs to each group for each blocks of 10 trials. The results were significant (P<.01) among three groups : relax and see (Cont.G.) > attention to the position except CS (Exp.G.2) > attention to CS position (Exp.G.1). On the latency of CRs, there were little difference between Exp.G.2 and Cont. G., but the latency of CRs in Exp.G.1 showed a tendency which CRs arose almost just before the presentation of UCS, the appearance of CRs was delayed : Cont.G.=Exp.G.2 < Exp.G.1. It was said that the visual attention of the subject had the inhibitory effects on the acquisition process of CR. The inhibitory effects became more larger than other when the position of visual attention was the CS presented position.
