Sentence examples for motion coherence detection from inspiring English sources

Subjects were trained over five days on a visual motion coherence detection task with either congruent audiovisual, or incongruent audiovisual stimuli.

Figure 2 shows the mean scores for the motion coherence detection task for all groups.

Equally, this result may indicate that motion coherence detection is a better indicator of visual processing that distinguishes lower reading ability from developmental dyslexia.

However, DD children did show significantly lower thresholds on the motion coherence detection task when compared with the RA children Z = -2.1, p <.05.

None of the five tasks purported to require parietal functioning (motion coherence detection, apparent motion 2-dot/4-dot detection, spatial misalignment task, length discrimination task, and attentive tracking task) showed predicted significant differences between dyslexic and age-controlled children.

The DD group's mean threshold for motion coherence detection (M = 12.59, SD = 10.41) was not significantly different from that of the CA control group (M = 11.74, SD = 7.60), Z = -0.2, p =.43.

Several research groups have started to explore alternative explanations, with important investigations into the M-dorsal visual stream using tests of motion coherence, change detection, and visual search [ 8, 9, 20, 21].

Alternatively, if ventral visual cortex is only engaged when motion contributes to form perception, then a ventral visual lesion should only impair motion perception when form representations are evoked (e.g. by structure-from-motion stimuli), but not when only basic motion perception is tapped (e.g. motion coherence or motion detection).

The perception of motion in basic, non-form tasks (motion coherence and motion detection) and complex structure-from-motion, for a wide range of motion speeds, all centrally displayed, was assessed in five patients with a circumscribed lesion to either the right or left ventral visual pathway.

> -wrap-foot> The behavioural findings implicate the right, but not the left ventral visual pathway, in contributing to normal central motion perception at a wide-range of motion speeds (detection at speed of 0.055 0.08°/s, coherence at speeds of 5.4 and 27.27°/s) and this was true even for tasks that did not involve form processing (motion coherence and motion detection).

If motion coherence was not detected, subjects were instructed to withhold responding.
