Bae(2024)APP.pdfPast perceptual experiences can shape our current perception. But is it always the case?
Our perceptual experiences are shaped by our recent perceptual experiences (the past) and the new perceptual inputs (the present). This is well established as serial dependence effect in the studies of visual perception. In our study, we found that this effect occurs depending on what stimulus is being perceived at a given moment in time. For example, when we perceive a simple line orientation that is perfectly vertical, then this perception won't be influenced by other orientated lines perceived before. However, when we perceive a line orientation that is tilted by 45°, then this perception is distorted by other orientations perceived before. This finding suggests that the visual system integrates our past experiences when it is useful for subsequent behavior. In the paper, we discuss the theoretical significance of this finding in more detail.
2022-FukudaEtAl-PsychSci.pdfWhat we see now can distort what we saw a moment ago.
We may believe that our memory of a recent visual experience is firm and stable. However, our new collaborative study with Fukuda lab at U.Toronto shows that the perception of a new stimulus systematically distorts our memory of a recent past. In the experiment, we had participants remember a simple visual feature (e.g., color) and reported what they saw. Critically, they had to do a perceptual comparison between their memory and a new stimulus prior to the report. We found that the memory report was biased toward the new stimulus when the participants think that the new stimulus was similar to the stimulus in their memory. Despite the memory distortion, the participants were confident about their report, suggesting that the distortion occurred unconsciously. So, yes, we believe that our memory of a recent visual experience is firm and stable, but the truth is that our memory is distorted! Now, imagine that you are selecting a ripe avocado in a grocery store. How green is the avocado you saw a second ago? The answer might be that it depends on the avocado you are looking at now!
