✦ Synopsis
Eight participants decided whether two-or three-dimensional bars embedded within twoor three-dimensional frames were semantically consistent with written inequalities of the form `A 4 B'. Inequalities were presented either before (Experiment 1) or after the graphs (Experiment 2). In Experiment 1, irrelevant depth cues were associated with slower decision times and there was no processing cost associated with an inconsistency between the dimensionalities of bars and frames. Memory encoding and retrieval times in Experiment 2 were aected by both graph complexity and consistency. Neither a depth consistency heuristic nor the maximum ink±data ratio principle can account for these results. More appropriate guidance for graph design will come from elaborating the working memory component of current cognitive models of graph processing.
