Document Summary
Still face experiment: age = infants (typically not used beyond 12 months, as early a three months, tries to measure quality of co-regulation (history of co-regulation between infants and parents, 3 different parts: Part 1 = baseline (mom and baby face-to-face. Goal is to get natural reflection of reaction. Arm hold: from about 6-12 months, focuses on child"s independent regulation, done in a lab with a highchair and table. The baby sits in the chair with arms on the table. Researcher (sometimes caregiver) goes behind baby, gently grabs arms, and holds them still to the table for 2 minutes (or 20 seconds in case of an intense negative reaction: 1 group of children has no emotional reaction. Their data must be thrown out: good regulators shift their gaze to anything other than their arm that might be distracting. Can maintain a calm: poor regulators engage in hard crying for 20 seconds.
