Abstract:
How language began is one of the oldest questions in science, but theories remain speculative due to a lack of direct evidence. Here, we report two experiments that generate empirical evidence to inform gesture-first and vocal-first theories of language origin; in each, we tested modern humans' ability to communicate a range of meanings (997 distinct words) using either gesture or non-linguistic vocalization. Experiment 1 is a cross-cultural study, with signal Producers sampled from Australia ( N = 30, M age = 32.63, s.d. = 12.42) and Vanuatu ( N = 30, M age = 32.40, s.d. = 11.76). Experiment 2 is a cross-experiential study in which Producers were either sighted ( N = 10, M age = 39.60, s.d. = 11.18) or severely vision-impaired ( N = 10, M age = 39.40, s.d. = 10.37). A group of undergraduate student Interpreters guessed the meaning of the signals created by the Producers ( N = 140). Communication success was substantially higher in the gesture modality than the vocal modality (twice as high overall; 61.17% ...
