Motion extrapolation in the flash-lag effect depends on perceived, rather than physical speed
2022, Vision ResearchCitation Excerpt :Such inconsistent effects led us to question whether these FLE findings might be due to changes in perceived, rather than physical velocity (Finke, Freyd, & Shyi, 1986; Makin, Stewart, & Poliakoff, 2009). Although physical velocity and perceived velocity are naturally closely correlated, the distinction is that (physical) velocity can be perceived differently depending on properties such as object contrast (Stone & Thompson, 1992), transiency/duration (Treue, Snowden, & Andersen, 1993), as well as spatial (Smith & Edgar, 1990) and temporal (Shen, Shimodaira & Ohashi, 2003) frequency. For this reason, we investigate the nature of the velocity representation that contributes to the neural computation that generates the perceived offset in the FLE.
Visual Control of Walking Speed in Drosophila
2018, NeuronCitation Excerpt :If natural optomotor turning behaviors were primarily guided by the direction of motion, rather than the speed, then the pattern dependence of the tuning would also be less important (Srinivasan et al., 1999). Interestingly, psychophysical experiments in humans indicate that the perception of speed can depend on both stimulus velocity and wavelength, and that perception may be speed-tuned in some regimes and TF-tuned in others (Shen et al., 2005; Smith and Edgar, 1990). These two regimes suggest there may be flexibility in the algorithm used to guide a behavior.
A Normalization Mechanism for Estimating Visual Motion across Speeds and Scales
2017, Current BiologyCitation Excerpt :Matching speed differences between conditions increase as Δ increases. Many variables can have strong effects on the perceived speed of a stimulus such as contrast [19], spatial frequency [8, 20], luminance and chrominance [21], or even attention [22]. Particularly for spatial frequency up to 2 cycles per degree (c/deg) [23, 24], it has been shown that stimuli with higher spatial frequency are perceived to move faster than stimuli with lower frequency.
Flicker adaptation or superimposition raises the apparent spatial frequency of coarse test gratings
2015, Vision ResearchCitation Excerpt :Apparent flicker rate was higher for counterphase-flickering gratings than for spatially-uniform fields of the same temporal frequency, and this effect increased with increasing spatial frequency especially at low flicker rates. On the other hand, Smith and Edgar (1990) reported the opposite effect: the perceived temporal frequency of the counterphase grating decreased with increasing spatial frequency. Either way, these studies showed that the spatial properties of a stimulus affected temporal perception.
