No SNARC Effect Among Left-to-Right Readers: Evidence From a Turkish Sample

Abstract

The spatial-numerical association of response codes (SNARC) refers to the faster left-hand responses to smaller numbers and faster right-hand responses to larger numbers. Although easily replicable in Western cultures the prevalence of the SNARC effect in other cultures has long been an issue. In the current study we aimed to replicate the SNARC effect in a parity judgement task with Turkish participants (N = 66) whose reading habits are entirely left-to-right. The results revealed no SNARC effect. To the best of our knowledge this is the first finding indicating the absence of regular SNARC effect among left-to-right readers in a classical parity judgement task. Based on these findings we suggest that investigations of cultural influences on spatial-numerical associations should take a broader perspective rather than only focusing on reading habits. © 2023 Elsevier B.V.
