Still face意思

"Still face" is a term used in developmental psychology and refers to an experiment designed to study the effects of emotional communication between caregivers and infants. The still-face experiment was developed by Edward Tronick and colleagues in the 1970s to understand how infants respond to a lack of emotional interaction from their caregivers.

During the still-face experiment, a caregiver (often the mother) interacts normally with an infant for a few minutes, followed by a period where the caregiver maintains a still face, showing no emotional expression or response to the infant's actions or sounds. This lack of interaction can cause the infant to become distressed as they are not receiving the usual social feedback and interaction they expect.

The still-face experiment is a way to observe how infants respond to a disruption in social communication and to understand the importance of emotional reciprocity in early social and emotional development. It has been used to study a variety of developmental issues, including attachment, social referencing, and the impact of stress on early development.
