The maximally discriminative facial movement coding system
Description:Surprise and joy expressions were most common, and negative expressions least common, in response to the jack-in-the-box, arm restraint, and masked-stranger situations, indicating a relative preponderance of positive expressions during these situations. Sex Differences No sex differences were found, as boys and girls were similarly apt to exhibit each expression in response to each situation. We hypothesized that infants would exhibit high rates of joy expressions during tickle. This was confirmed, as more infants exhibited joy expressions than any other expression. Furthermore, joy expressions were not the most common response to any other situation, indicating that the predicted specificity was found for joy expressions. Second, we hypothesized that a negative expression such as anger or disgust would be the most common response to sour taste, but we did not anticipate that the most common expression would be sadness.
