Embodied markedness of parity? Examining handedness effects on parity judgments

摘要: Parity is important semantic information encoded by numbers. Interestingly, there are hand-based effects in parity judgment tasks: right-hand responses faster for even and left-hand odd As this effect was initially explained the markedness of words vs. right left, it denoted as linguistic response codes (MARC) effect. In present study, we investigated whether MARC differs left handers. We conducted a task, which right- left-handed participants had to decide presented single or two-digit number pressing corresponding key. found that handedness modulated unit digits. While replicated regular handers, no evidence However, closer inspection revealed handers depended on degree left-handedness with reversed most participants. Furthermore, although tens digits interfered processing digits, not handedness. Our findings discussed light three different accounts effect: account, polarity correspondence principle, body-specificity hypothesis.
