Emerging work suggests that acute, moderate-intensity aerobic exercise may help to subserve episodic memory of neutral stimuli. Less investigated, however, is whether acute exercise is associated with enhanced memory recognition of emotional stimuli, which was the purpose of this experiment. A parallel-group randomized controlled experiment was employed. Participants (mean age = 20 yr) were randomized into an exercise (n = 17) or control group (n = 17). The exercise group engaged in a 15-min bout of moderate-intensity treadmill walking. Emotional memory recognition was assessed via images from the International Affective Picture System, including assessments of varying degrees of valence and arousal. Memory recognition was assessed at 1 day, 7 days, and 14 days post-memory encoding. We observed a significant main effect for time (F(2) = 104.2, p < 0.001, η2p = 0.77) and a significant main effect for valence–arousal classification (F(4) = 21.39, p < 0.001, η2p = 0.40), but there was no significant time by group interaction (F(2) = 1.09, p = 0.34, η2p = 0.03), classification by group interaction (F(4) = 0.12, p = 0.97, η2p = 0.01), time by classification interaction (F(8) = 1.78, p = 0.08, η2p = 0.05), or time by classification by group interaction (F(8) = 0.78, p = 0.62, η2p = 0.02). In conclusion, emotional memory recognition decreased over the 14-day follow-up period and this rate of memory decay was not altered by acute moderate-intensity exercise engagement. We discuss these findings in the context of exercise intensity and the temporal effects of exercise.

Memory Recognition

Prior theoretical work on memory schemas, an influential concept of memory from the field of cognitive psychology, is presented for application to fidelity of computer graphics simulations. The basic assumption is that an individual's prior experience will influence how he or she perceives, comprehends, and remembers new information in a scene. Schemas are knowledge structures; a scene could incorporate objects that fit into a specific context or schema (e.g., an academic's office) referred to as consistent objects. A scene could also include objects that are not related to the schema in place referred to as inconsistent objects. In this paper, we describe ongoing development of a rendering framework related to scene perception based on schemas. An experiment was carried out to explore the effect of object type and rendering quality on object memory recognition in a room. The computer graphics simulation was displayed on a Head Mounted Display (HMD) utilizing stereo imagery and head tracking. Thirty-six participants across three conditions of varied rendering quality of the same space were exposed to the computer graphics environment and completed a memory recognition task. Results revealed that schema consistent elements of the scene were more likely to be recognized than inconsistent information. Overall higher confidence ratings were assigned for consistent objects compared to inconsistent ones. Total object recognition was better for the mid-quality condition compared to the low-quality one. The presence of shadow information, though, did not affect recognition of either consistent or inconsistent objects. Further explorations of the effect of schemas on spatial awareness in synthetic worlds could lead to identifying areas of a computer graphics scene that require better quality of rendering as well as areas for which lower fidelity could be sufficient. The ultimate goal of this work is to simulate a perceptual process rather than to simulate physics.
