Scoring A system was devised to code parent interactions. The code and the behavioral definitions are presented below. Scoring was done using a ten second interval method in which the first occurrence of each category in an interval was recorded. Results Videotape were dubbed with a ten second audio track to facilitate coding. Five researchers coded the tapes of Participant A and four coded Participant B. Average for all scorers were graphed and these are presented here.
Similarities exist across all three graphs.
A very common activity of parents, largely independent of the child's age, is to teach the child what objects do by using them , and then requesting that the child do the same. The second common training area is in labeling of stimuli. All parents provide labels of objects to their child, although Participant B's level of labeling is much less. Even though the daughter of Participant B was the same age as the first data point in the UC Davis sample, this father used very low levels of label training. These are virtually absent in the under one-year dyads.
