Distortion of Memory Drawings for Real-World Scenes by the Presence of Incongruent Objects

Previous work has found that visual memory has highly detailed and diagnostic features when evaluated by a free recall drawing task (Bainbridge et al., 2018). Drawings can thus be used to reveal the nature of representations within memory. One question of interest is the effect of incongruent or schema-inconsistent objects on memory recall of a larger scene. Previous literature has shown mixed results on these effects. In this study, we investigate how content of visual memory changes based on the congruency of objects within scenes. 30 participants were eye-tracked while viewing 12 scenes, each containing a single congruent or incongruent object. For example, a pool scene contained either a congruent beach ball or an incongruent microscope. Following a distracting task, they were tested with the drawing task as well as recognition tests. Participants drew an average of 8.4 images from memory with 4.2 correct object/scene pairings, with no significant differences between incongruent and congruent scenes. Interestingly, participants made significantly more object/scene binding errors for incongruent scenes, errors not seen in our prior work. These errors were either objects remembered in isolation, or transposed into incorrect scenes. Differences were also found in eyetracking patterns and drawing stroke order for incongruent versus congruent scenes. Free recall drawings provide a powerful method of investigating nuanced visual memory recall effects created by the presence of incongruent objects.
