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

Frontiers in human neuroscience, 2018

Research from multiple areas in neuroscience suggests a link between self-locomotion and memory. In two free recall experiments with adults, we looked for a link between (a) memory, and (b) the coherence of movement and optic flow. In both experiments, participants heard lists of words while on a treadmill and wearing a virtual reality (VR) headset. In the first experiment, the VR scene and treadmill were stationary during encoding. During retrieval, all participants walked forward, but the VR scene was stationary, moved forward, or moved backwards. In the second experiment, during encoding all participants walked forward and viewed a forward-moving VR scene. During retrieval, all participants continued to walk forward but the VR scene was stationary, forward-moving, or backward-moving. In neither experiment was there a significant difference in the amount recalled, or output order strategies, attributable to differences in movement conditions. Thus, any effects of movement on memor...

An Investigation of Visual Memory: The Nexus Between Visual Perception and Memory

2018

Memory is one of the oldest and most researched cognitive domains, and while much is established about verbal memory, research about visual memory is largely inconclusive. Past research acknowledges that visual memory is a complex function and research regarding visual perception, in particular the two streams hypothesis, clearly highlights an anatomical and functional demarcation between spatial and object processes. The current project consists of three experiments that investigate performance on a series of visual memory tasks that were designed to measure memory for spatial information and for object information separately. Each of the experiments extended upon the results and ideas that emerged from the previous experiment's findings.The purpose of the three experiments included: 1. The development and piloting of an electronic visual memory test battery that has clear assessment tasks that measure spatial and object abilities separately for short term, working and long ter...
