Stroboscopic visual training improves information encoding in short-term memory.
Abstract
The visual system has developed to transform an undifferentiated and continuous flow
of information into discrete and manageable representations, and this ability rests
primarily on the uninterrupted nature of the input. Here we explore the impact of
altering how visual information is accumulated over time by assessing how intermittent
vision influences memory retention. Previous work has shown that intermittent, or
stroboscopic, visual training (i.e., practicing while only experiencing snapshots
of vision) can enhance visual-motor control and visual cognition, yet many questions
remain unanswered about the mechanisms that are altered. In the present study, we
used a partial-report memory paradigm to assess the possible changes in visual memory
following training under stroboscopic conditions. In Experiment 1, the memory task
was completed before and immediately after a training phase, wherein participants
engaged in physical activities (e.g., playing catch) while wearing either specialized
stroboscopic eyewear or transparent control eyewear. In Experiment 2, an additional
group of participants underwent the same stroboscopic protocol but were delayed 24 h
between training and assessment, so as to measure retention. In comparison to the
control group, both stroboscopic groups (immediate and delayed retest) revealed enhanced
retention of information in short-term memory, leading to better recall at longer
stimulus-to-cue delays (640-2,560 ms). These results demonstrate that training under
stroboscopic conditions has the capacity to enhance some aspects of visual memory,
that these faculties generalize beyond the specific tasks that were trained, and that
trained improvements can be maintained for at least a day.

interests primarily concern the brain mechanisms underlying visual cognition, how
these capabilities differ among individuals, and how they can be improved through
behavioral, neurofeedback, and neuromodulation interventions. Within the field of
