3V0581.01 Increased Specificity: 8/26/79;

By now it is clear that Peggy is trying to communicate (orally) on a
wider scale. “Dat, dat, dat” lacked any specificity and soon outran its
usefulness. She then developed a remarkable range by merely varying
the pitch on a neutral syllable [***], repeated several times. Now she
seems to be trying hard to be more specific in her communications,
since pitch has been taken to its limits. Perhaps she has developed this
willingness for oral communication from observing our reactions to
her noises. Attention is prompt, but service is often slow because we
don’t know what she is after. But we question her out loud [is it this,
do you want ____, etc.] trying to find what is on her mind. She can see
that there are many different things to say, and saying the “right”
words leads to swifter and better (from her point) reactions from
others, i.e. she gets what she is after and gets it faster.
