Now, beginning with the first video clip @50.05, to suggest that in any shape or form that this "demonstration" is not only without a scintilla of Developmental awareness or for that matter simply human emotional/dialogue interaction and is nothing other than shameful dog, robotic, automaton reinforcement would be stretching the boundaries of the conceivable. Why not, just a ridiculous thought, shall we say, "engage" the child in simple back and forth emotional reciprocity with an iota or two of symbolic ideation thrown in for good measure? For example: As child is placing blocks, suggest, say, stretch your limits and say, "Wow, is that a train? I don't know, I'm not sure, a car?" In other words, engage him in the ACTIVITY of human-heartedness and engagement rather than providing his reinforcer choice (which severely aids to curtail and diminish engagement, not aid), analogous to "Polly want a cracker?" "Good Job, awesome! Polly get's a cracker, and another and another."
