Large-Scale Web- Based Psychophysics
Perceiving the timing and sequence of events is a fundamental component of human cognition. Disruptions in this temporal processing can cascade into broader cognitive deficits and have been implicated in several neuropsychiatric conditions, including schizophrenia.
With the increasing need for scalable and accessible cognitive assessment tools, online experiments are emerging as a powerful approach for investigating perceptual and cognitive functions in diverse populations. We demonstrate the feasibility of conducting web-based psychophysical experiments using precisely timed visual stimuli. Using the two-flash fusion task, we collected large-scale data alongside self-report questionnaires. Our findings replicate the well-established decline in visual temporal acuity with ageing. Strikingly, we also observe that individuals who report more frequent anomalous perceptual experiences and higher levels of schizotypal traits tend to exhibit better visual temporal acuity. These results challenge conventional assumptions and open new avenues for understanding the relationship between temporal perception and atypical cognitive experiences. Overall, the findings highlight the promise of web-based psychophysics as a valid and scalable method for studying individual differences in perception and cognition across broad populations.
