 Numbers are highly relevant in our everyday lives. Besides intentionally processing number magnitude when necessary, we often automatically process it even when not required. The SNARC (Spatial-Numerical Association of Response Codes
  Dehaene et al., 1993) effect, describing faster left-/right-sided responses to smaller/larger numbers, respectively, provides evidence for this automaticity. It arises in semantic number-processing tasks both, when number magnitude is task-relevant (e.g., magnitude classification) and task-irrelevant (e.g., parity judgment). However, findings on the SNARC effect in tasks requiring the processing of nonsemantic number features are mixed: While it has been observed in orientation judgment tasks, it was mostly absent in color judgment tasks. Importantly, previous studies were underpowered or did not control for confounding variables. In two highly powered online experiments, we found a small but significant SNARC effect in both nominal color judgment (cyan vs. yellow
  slope = -1.71 ms) and color intensity judgment (light cyan vs. dark cyan
  slope = -1.13 ms) of Arabic digits from 1 to 9 excluding 5, which did not significantly differ in size. Further, we found little evidence for the Linguistic Markedness of Response Codes (i.e., faster left-/right-sided responses to odd/even numbers, respectively
  Nuerk et al., 2004) effect. Moreover, the odd effect (i.e., faster responses to even than to odd numbers
  Hines, 1990) was detected. Taken together, both magnitude and parity are processed automatically even if participants respond to physical nonsemantic and nonspatial number features, but the spatial mapping seems more automatic for magnitude than for parity.
