Abstract: Points out that people can have continuous visual experience of an object's movement across a display even if the movement's middle phase takes place behind an opaque screen. This article considers explanatory issues pertaining to this so-called tunnel effect, focusing on J. J. Gibson's (1979) perception theory and the visual activity known as reflective seeing. The author suggests that, in tunnel experiments, there occur both persisting perception and persistence perception. Subjects have visual experience of the continued existence and movement of an object while it is out of sight. The author argues that the tunnel effect is a phenomenon of both straightforward and reflective seeing. Reports of straightforward and reflective seeing, and those about the object's going out of and coming back into sight, must be based on the kind of visual experience that is part of reflective seeing.
