Two laboratory experiments evaluated short-term retention of information from verbal and symbolic signs after following verbal (auditory mode) and pictorial (visual) forms of interfering activities. A differential interference effect was observed consistent with the .dualcoding hypothesis. From a practical viewpoint, neither type of Sign appeared superior in terms of its likely retention in short-term memory by drivers.
