<p><strong>Original citation.</strong> Ganor-Stern, D., & Tzelgov, J. (2008). Across-notation automatic numerical processing. <em>Journal of Experimental Psychology: Learning, Memory, and Cognition, 34</em>(2), 430-437.</p> <p><strong>Target of replication.</strong> This study seeks to replicate the original authors' finding of a CDE for pairs of numbers written in different forms, in both RT, F(1, 28) = 26.69, p &lt; .001.</p> <p><strong>A priori replication criteria.</strong> A successful replication would find that larger, rather than smaller, numeric differences would be associated with better performance (shorter RTs and lower ER) on the same-different task.</p> <p>We plan to conduct a 3 (Notation: Arabic, Indian, Mixed) x 2 (Numerical difference: small, large) x 2 (Task order: first, second) mixed ANOVA. Notation and Numerical difference are within-participants variables; Task is a between-participants variable. </p> <p>Participants all reported that they were native Arabic speakers. We plan to exclude from our analyses any trials with response times shorter than 200 ms or longer than 2,500 ms; this was the same exclusion criteria Ganor-Stern and Tzelgov used.</p>
