Audiovisual Perception Interaction with Emotion to Impact Memory recall of human faces
Arts and Sciences
We experience and remember the world through multiple sensory channels. Our memory of a given event can involve visual information, auditory information, or both simultaneously. The degree to which an event is emotionally evocative is also variable across experience and modulates memory. Eyewitness accounts with these different characteristics are used as evidence in criminal court testimony in the attempt to distinguish guilt and innocence. To address this issue, the current study aimed to identify how audiovisual perception may interact with emotion to impact memory recall of human faces. Faces were presented to participants in three different ways: faces with no audio, faces with neutral audio, or faces with negative/emotional audio. In our subsequent identification and recognition tasks, we included familiar faces (one that has been seen before), similar faces (60% altered image from previously seen), and novel faces. The design of the current study provides information about how audiovisual and emotional systems interact to impact subsequent processing. Furthermore, the current work may help us understand the influential factors that may increase or decrease the accuracy of eyewitness testimonies.
