Answer:
Still face
Step-by-step explanation:
Still face as described by Tronick and Weinberg is a phenomenon in which an infant, after three minutes of “interaction” with a non-responsive expressionless mother, “rapidly sobers and grows wary.He makes repeated attempts to get the interaction into its usual reciprocal pattern. When these attempts fail, the infant withdraws orients his face and body away from his mother with a withdrawn, hopeless facial expression.”
