The researchers' objective, as with half a dozen similar projects under way in the lab, was to explore what infants understand about social groups and social expectations.
Before the end of their first year, for example, infants understand that people sometimes have competing goals, and they take notice of whether one individual helps or hinders another.
This research suggests that infants understand more about objects earlier than Piaget proposed.
Initially, infants understand only that an object must be in contact with another surface in order to be supported (i.e., not fall).
Human infants understand communicative intentions expressed in pointing gestures even prelinguistically (Behne et al. 2005).
However, studies have shown that infants understand highly variable speech (e.g., Kuhl et al., 2008) as well as foreign-accented input from around 14 months (e.g., Schmale & Seidl, 2009).
If the infant understands the implicit rules, he or she will show little interest in an expected situation, but will stare at images of a surprising event.
Early attachment factors included the mother's perception of within the first five weeks postpartum being able to be calm and comfort her baby, understand the infant's needs, and recognize the cues of hunger; response categories were, "always", "usually", "seldom", and "never".
Observe newborns and infants, see also, Understand Baby Health by Poop Colors, Stool: Newborns early-on will pass a dark green stool called meconium, which is normal, as are: Breast-fed infants often producing yellow-green, green-brownish stool colors.
Cues such as the caregiver's gaze, body language, gesture, and smile help infants to understand the meanings of words.
