Visual acuity
Consideration of how eye movements in reading are controlled exposes a problem with this account. Visual acuity is restricted, so the question of how the eyes can be selectively and accurately directed to particular words arises. When the target is so visually degraded as to be virtually invisible, how is this achieved? Furthermore, if the target of such reinspections is the point where a faulty attachment was made, does this not imply that the reader was, in some sense, already aware of the potential problem?
