The present study tested the influence of stimuli emotional valence, emotional arousal, and typicality on memory recollection in three groups of participants exposed to the same environment through different modalities: in vivo exposure (i.e., real-life), 3D virtual reality (i.e., VR), and 2D pictures. Context-related free-recall, recognition accuracy, and recognition confidence were analyzed. The results showed that memory performance was best in the real-life modality, and participants in the VR and 2D pictures modalities performed comparably. Interesting effects of stimuli emotional valence and typicality emerged: in the VR and 2D pictures modalities, positive items were better recalled than negative items; typicality was relevant only in the real-life modality, with less common objects within the explored setting (i.e., an office) recalled more often. Furthermore, recognition accuracy and confidence were significantly higher in the real-life modality than in the VR and 2D pictures modalities. Further research is needed to support the creation of VR environments that are sufficiently comparable to real-life contexts in order to obtain higher ecological validity in studies of cognitive performance. In particular, the impact of stimuli typicality and emotional valence in VR contexts should be investigated to gain insight into how these features might improve memory recall in virtual scenarios.

Abstract

The present study tested the influence of stimuli emotional valence, emotional arousal, and typicality on memory recollection in three groups of participants exposed to the same environment through different modalities: in vivo exposure (i.e., real-life), 3D virtual reality (i.e., VR), and 2D pictures. Context-related free-recall, recognition accuracy, and recognition confidence were analyzed. The results showed that memory performance was best in the real-life modality, and participants in the VR and 2D pictures modalities performed comparably. Interesting effects of stimuli emotional valence and typicality emerged: in the VR and 2D pictures modalities, positive items were better recalled than negative items; typicality was relevant only in the real-life modality, with less common objects within the explored setting (i.e., an office) recalled more often. Furthermore, recognition accuracy and confidence were significantly higher in the real-life modality than in the VR and 2D pictures modalities. Further research is needed to support the creation of VR environments that are sufficiently comparable to real-life contexts in order to obtain higher ecological validity in studies of cognitive performance. In particular, the impact of stimuli typicality and emotional valence in VR contexts should be investigated to gain insight into how these features might improve memory recall in virtual scenarios.
