Ballard et al.'s target article makes an important contribution to the embodiment story by suggesting how limitations on neural binding ability lead to deictic strategies for many tasks. It also exploits the powerful experimental method of instrumented virtual reality. This commentary suggests some ways in which the target article might be misinterpreted and offers other cautions.

What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the connectionist models and their implications is one book that we really recommend you to read, to get more solutions in solving this problem.

But no one believes that children learn the grammar of their native language independent of meaning (semantics) and use (pragmatics). Recent results suggest that is now possible, although still very difficult, to build computational and formal models of how children learn language. This paper will review some recent developments in computational modeling of language acquisition and suggest how they might be extended to grammatical inference.

Little is known, however, about the nature of the integrative process. By using a task which requires the integration of spatial position information from different fixations, it is demonstrated that visual information from previous fixations is preserved in a world-centered representation which is precise enough to support judgements of geometric shape. It is also shown that successive views are aligned with respect to common visual features, indicating that visual stability may be normally accomplished by a visual matching strategy in combination with cancellation by an eye-position signal.

The whole concept of ‘truth through disputation’ is alien to my scientific tradition and I agree with Rispoli that RI is not helped by the polemical tone. There is a companion volume and software suite by Kim Plunkett & Jeff Elman (1997), Exercises in rethinking innateness , which we have used in an undergraduate cognitive science course. This is, in my opinion, the best source for understanding the main point of RI, which I summarized for the class as: the book tries to show that PDP learning techniques have advanced to the point where we need not assume that tabula rasa learning of language must be ruled out. The Exercises in RI book and particularly doing the on-line examples give the students direct intuition about this claim. Our students were impressed by the Tlearn system, but understood its limitations and were not convinced either of the main claim of RI or of the radical nativist alternative.

The attempt to bolster this position with computational arguments is misleading and often just wrong. Fortunately, other efforts are making progress in linking neural and cognitive development.
