Emotional signals are crucial for sharing important information with others, for example to warn them of danger or to share enjoyment. We use many different signals to communicate to others how we feel, including facial expressions, vocalizations, and gesture. In our work, we address questions of how expressions are learned from cultural rules, and which aspects expressions develop even with very sparse input. We use a range of tools to investigate the roles of biological and cultural factors in emotional communication, including comparisons of perceptual and linguistic processes in different cultural groups, and studies the similarities and differences between human and chimpanzees vocal expressions and emotional vocalizations by congenitally deaf adults.
