a Pseudowords and shapes used in Experiment 1. Left column: Bouba-like words and shapes. Right column: Kiki-like words and shapes. Pronunciation transcripts for Bouba-like words: /bu:ba:/, /hʊhʊ/, /laʊlaʊ/, /du:bu:lu:/, /kʊmʊlʊ/, /məlʊba:/, /kaʊkaʊ/, /daʊdaʊ/, /lʊmʊbʊ/, /noʊboʊmoʊ/. Pronounciation transcripts for Kiki-like words: /kɪki:/, /nɪbɪti:/, /kɪdɪ ni:/, /zɪmɪti:/, /hɪnɪti:/, /nɪkɪmi:/, /heɪlɪki:/, /ta:keəa ti:/, /beɪmeɪleɪ/, /t∫ɪtki:/. b Kikiness (fraction of participants who selected a Kiki-like word) plotted for each shape. Error bars represent standard error of mean across participants calculated after scoring responses as 0 for Bouba and 1 for Kiki. The correlation coefficient between the Kikiness from odd- and even-numbered participants is shown (top left). Asterisks beside the correlation coefficient indicates its statistical significance (**** isp <.0005). c Average Kikiness for curved (blue) and angular (red) shapes. Error bars represent standard error of mean across shapes of the Kikiness averaged across participants. Asterisks indicate statistical significance of the comparison (rank-sum test across Kikiness for 10 curved and 10 angular shapes, **** isp <.0005). (Color figure online)
