Retrieving Against the Flow: Incoherence Between Optic Flow and Movement Direction Has Little Effect on Memory for...

Area of Science:

• Neuroscience
• Cognitive Psychology

Background:

• Neuroscience research suggests a link between self-locomotion and memory.
• Theories of hippocampal function and cognitive psychology propose movement influences memory.

Purpose of the Study:

• To investigate the relationship between memory recall and movement coherence/optic flow.
• To test if self-locomotion during encoding or retrieval affects memory performance.

Main Methods:

• Two free recall experiments were conducted with adult participants.
• Participants listened to word lists while on a treadmill and wearing a virtual reality (VR) headset.
• Movement conditions (stationary vs. moving VR scene, forward vs. backward) were manipulated during encoding and retrieval phases.

Main Results:

• No significant differences in the amount of words recalled were found across different movement conditions.
• No significant differences in output order strategies were observed based on movement conditions.

Conclusions:

• The study's findings indicate that effects of self-locomotion on memory are more limited than previously theorized.
• Movement coherence and optic flow do not appear to significantly modulate memory recall in these experimental paradigms.
