It is suggested that one of the determinants of autokinesis is noise associated with a hypothesized eye‐in‐head position monitor within the oculomotor system. It is argued that a decrease in convergence of the eyes is associated with a decrease in the magnitude of the signal relating to eye position. The prediction is that this will thereby produce an increase in the effectiveness of noise as a spurious signal. An experiment is described in which a just‐visible oscilloscope spot was viewed in a dark room at four distances along the subject's median sagittal plane. The latency of appearance of autokinetio movement was measured in each of these conditions. It was found that as distance increased, i.e. as convergence decreased, latency decreased also. This result is consistent with the prediction.
