Current approaches to automated analysis have focused on a small set of prototypic expressions (e.g., joy or anger). Prototypic expressions occur infrequently in everyday life, however, and emotion expression is far more varied. To capture the full range of emotion expression, automated discrimination of fine-grained changes in facial expression is needed.(More)
The face is a rich source of information about human behavior. Available methods for coding facial displays, however, are human-observer dependent, labor intensive, and difficult to standardize. To enable rigorous and efficient quantitative measurement of facial displays, we have developed an automated method of facial display analysis. In this report, we(More)
The timing of switching pauses is critical to mother-infant synchrony. The relation between switching-pause duration and maternal depression was studied in 15 depressed and 20 nonde-pressed mother-infant dyads. Switching pauses of depressed mothers were longer, more variable, and less consistent with scalar timing. mother-infant interaction vocal timing(More)
