It is said that conventional gestures for numbers differ by culture. Conventional gestures are thought to imply consistency of form both across and within individuals. The present study tests the consistency of finger gestures of 60 participants of three different cultures and in three different mother tongues in nine different hypothetical scenarios. The first subject of analysis is whether participants differentiate between counting and signaling. The second subject is the consistency of gestures within and between groups. The third is how participants depict the number 1. Result show that most people use the same gestures for counting and signaling. In addition, Germans and English Canadians show relatively low degrees of individual differences whereas French Canadians show relatively high degrees of individual variability. Furthermore, only the Germans use the thumb to indicate the number 1, whereas the two North American cultures use the index finger. The present data suggest that finger gestures of some cultures clearly qualify as conventional gestures whereas others do not. It is suggested that the development of conventional gestures is influenced by cultural exposure, which can even result into the loosening of conventions.
