A syntactic parser is described for hierarchical concatena-tion patterns that are presented to the analyzer in the form of linear strings. Particular emphasis is given to the system of “significant addresses” by means of which processing times for large-scale matching procedures can be substantially reduced. The description makes frequent use of examples taken from the fully operational implementation of the parser in an experimental English sentence analyzer. By structuring an area of the computer’s central core storage in such a way that the individual locations of bytes and bits come to represent the data involved in the matching procedure, the shifting of information is reduced to a minimum, and the searching of lists is eliminated altogether. The matches are traced by means of binary masks and the state of single bits determines the operational flow of the procedure. The method could be implemented with any interpretive grammar, provided it can be expressed by the functional classification of the items composing the input hierarchical structures.

The report contains a discursive description and flow diagrams of the machine program written for a GE 425 computer in order to implement the previously developed “Multistore Procedure.” Advances in several related problem areas are reported: Classification of words in terms of “correlation indices, i.e. by means of code numbers representing the words” possibilities of forming syntatic combinations with others; Reclassification, i.e. assignation of correlation indices to word combinations; Correlator range, i.e. the extent of syntactic government – in this case of prepositions – in English sentences; Grammatical and semantic factor analysis, i.e. analysis of grammatical functions and semantic content in terms of constant factors.

The linguistic-type skills of a young chimpanzee (Pan) acquired in a computer-controlled language-training situation are reviewed. Those skills include facile acquisition of vocabulary, object naming, color naming, appropriate use of “yes” and “no” in response to certain questions, and conversation. In conversations the subject has formulated novel sentences and without special training has asked that objects be named, whereupon requests were made that they be given to her. These findings are interpreted in terms of how enriched environments can serve to bring forth novel communication skills in the chimpanzee, which is otherwise alinguistic; how the challenge of the environment can serve to limit manifest intelligence; and how a cognitive, rather than the traditional stimulus-response, framework is required for understanding the communication skills and psychological processes of the chimpanzee.
