The realism paradox: Realism can act as a form of signaling despite being associated with cognitive load

Abstract

Realistic graphics have been found to result in a worse learning performance than schematic visualizations. These negative results of realism are usually explained by assuming that realistic visualizations induce more cognitive load. Therefore, realism has been linked to the facet of extraneous cognitive load in the model of cognitive load theory. However, recent results indicate that realism may be used to good advantage when it is utilized only in selected parts of visualizations. We tested the hypothesis that realism can be used as a form of signaling. In an experimental study (N = 50), we presented each participant with one realistic and one schematic anatomical visualization. As predicted, retention performance was highest for the realistic components. Furthermore, we found that extraneous load ratings were overall higher when a particularly detailed visualization was shown to participants (although no main effect of realism was found). Our results can be explained in terms of the disfluency effect, which holds that more visually demanding learning materials can in some cases enhance learning. An important implication of the study is that educators may use the degree of realism to focus learners' attention.

  • Recent investigations of digital and online learning have brought to light results that can pose a challenge for cognitive load theory.

    “recent investigations centering on the new affordances of digital and online learning have brought to light several results that can pose a challenge for the theory (e.g., Brom et al., 2018; Skulmowski et al., 2016; Skulmowski & Rey, 2020b).”
  • Skulmowski and Rey (2020b) found that when realistic and schematic visualizations are presented alongside each other in a learning task, retention performance for the realistic parts of the learning material is higher.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
