learning social cues before speaking language (habitus)

A study that recently came out of University of Washington:

"Each toy had movable parts that made sounds, such as a strand of plastic beads that made a rattle when dropped into a plastic cup and a small box that "buzzed" when pressed with a wooden stick. The children watched eagerly – leaning forward and sometimes pointing enthusiastically.

Then a second person, referred to as the "emoter," entered the room and sat down on a chair near the table. The experimenter repeated the demonstration and the emoter complained in an angry voice, calling the experimenter's actions with the toys "aggravating" and "annoying."

After witnessing the simulated argument, the children had a chance to play with the toys, but under slightly different circumstances. For some, the emoter left the room or turned her back so she couldn't see what the child was doing. In these situations, toddlers eagerly grabbed the toy and copied the actions they had seen in the demonstration.

In other groups, the angered emoter maintained a neutral facial expression while either watching the child or looking at a magazine. Most toddlers in these groups hesitated before touching the toy, waiting about four seconds on average. And when they finally did reach out, the children were less likely to imitate the action the experimenter had demonstrated."
