Post-hoc analyses with Bonferroni corrections showed no significant Notation effect at all sites, but a significant Magnitude effect for Arabic numerals at all three sites (Left, p<.05; Middle, p<.05; Right, p<.05), such that small Arabic numerals elicited larger N1 (M = −3.00, −2.27, −2.95 µV, respectively) than large Arabic numerals (M = −2.33, −1.64, −2.38 µV, respectively).
The researchers plugged their data into a computer model, which then generated the most likely family tree for all the languages' numeral systems.
The titles on their 2013 debut EP, I Have Lost All Desire For Feeling, were all Roman numerals.
For example, the Champernowne sequence, consisting of all the binary numerals for every non-negative integer listed consecutively (i.e., 011011100101110111…), is Borel normal.
And yet we know (because PrfF x, y) strongly represents the proof relation) that for any numeral n, F can prove ¬PrfF n, ⌈GF⌉).
Because discriminability was dependent on magnitude for dots but not for numerals, the difference between two choices corresponding to a given perceptual increment depends on magnitude for dots, but not for numerals; i.e. the perceptual value of numerals increases almost linearly with increasing magnitude, but the perceptual value for dot arrays falls off with magnitude (Fig. 4a).
In a study using the same paradigm as the present one, as well as the Posner task with either endogenous or exogenous attentional cues, we found that the SNARC effect was constantly attenuated for the large numerals (8 and 9) in the parafoveal condition of all three tasks, especially for Chinese numerals and in the task with exogenous cues [56].
The second posterior positivity (P2p) component showed a greater positivity for Arabic numerals closer to our comparison numerical standard of five as compared to those further away, replicating previous findings [ 12, 20].
Many of the marks are simple combinations of lines, but the authors contend that some resemble early characters for "eye" and for several Chinese numerals.
A headline that is graphically salient in some way has a greater chance of capturing our eye, and in an environment where dozens of headlines and stories vie for attention, numerals break up the visual field.
