Abstract

Human information processing is divided into two processing modes. One is a conscious, attention-demanding method that is flexible and can be readily controlled. The second is an unconscious, essentially uncontrolled processing that is triggered by well-practiced stimulus-response associations. This paper contains a description of two types of errors to which unconscious processing is prone: illusory combinations of display elements and interference from conflicting irrelevant display elements. Traffic guide signs that may be susceptible to unconscious (automatic) processing errors are also presented as well as research results that are consistent with the hypothesized errors.
