Sentence examples for motion coherence sensitivity from inspiring English sources
Yet, only improved averaging explains developments in motion coherence sensitivity.
The ability to extract signal from noise may be another limiting factor on motion coherence sensitivity in development, alongside sampling.
Instead, developmental increases in motion coherence sensitivity appear to be driven solely by age-related increases in sampling.
Our study also allowed us to test the suggestion that motion coherence sensitivity may mature at different rates for different speeds.
Furthermore, the gradual development of motion coherence sensitivity with age appears to be due to improvements in sampling rather than reductions in internal noise.
In this study, we sought to determine whether the development of motion coherence sensitivity is limited by internal noise (i.e., imprecision in estimating the directions of individual elements) and/or global pooling across local estimates.
To characterize sensitivity to motion coherence, we calculated the proportion of coherently moving dots required to detect the fast coherent motion (27.27°/s) embedded in dots moving in random directions (Green, 1961; Levinson and Sekuler, 1976; Meteyard et al., 2008; Gilaie-Dotan et al., 2013).
For this reason, d' was used to measure sensitivity to detect motion coherence and c was used to measure the decision criterion [98].
Indeed, the use of motion coherence as a measure of magnocellular sensitivity has recently come under scrutiny [ 36].
Computer-based assessments included measures of visual sensitivity (central and peripheral motion coherence thresholds), transient spatial attention (a useful field of view - dual task paradigm), and sustained attention (multiple-object tracking).
In a recent study, we showed that 5- to 9-year-old children born at < 32 weeks gestation were impaired, relative to full-term peers, in their sensitivity to global form cues, cues that signal global movement patterns (i.e., global motion coherence), and SFM cues signaling the presence of a globally coherent point-light walker within a mask (Taylor et al., 2009).
