Visually guided, aimed movements can be unaffected by stimulus-response uncertainty.
Article in Experimental brain research, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Response times generally increase linearly with the logarithm of the number of potential stimulus-response alternatives (e.g., Hick's law). The ubiquity and theoretical importance of this generalization make exceptions particularly interesting. Recently, Kveraga et al. (Exp Brain Res 146:307, 2002) added a third to the two previously known exceptions, demonstrating that saccade latencies were unaffected by stimulus-response uncertainty. They suggest that visually guided saccades are exceptional, because these movements can be automatically selected using a privileged pathway: the topographically organized regions in superior colliculus that convert spatially coded visual activity into spatially coded motor commands. We report that visually guided, aimed hand movements also are unaffected by both stimulus-response uncertainty and stimulus-response repetition. A second experiment demonstrated that this lack of an uncertainty effect persists for equiluminant stimuli. This result suggests that posterior parietal cortex is not the privileged pathway eliminating stimulus-response uncertainty for hand movements. Because hand movements are not guided by mechanisms in the superior colliculus, our results cast doubt on the privileged-pathway hypothesis, at least for hand movements. Instead, the absence of stimulus-response uncertainty may occur only in tasks that do not require the stimulus to be associated with a response effector and that have high stimulus-response compatibility.
