Dr. Susan W. Gray

While Susan W. Gray is known primarily for her work with the Early Training Project, a pioneering early intervention program with low-income black children, she has also influenced the development of school psychology and the creation of Early Childhood Education as a discipline. In addition, in her own quiet way, she has supported the career development of a number of professional women who have had impact on child development, early childhood education, and school psychology. Four major themes are used to present Susan Gray's biography: (1) being ahead of her time in terms of thinking which allowed her to take advantage of opportunities; (2) the role of serendipity versus long-range planning of career trajectories; (3) specific influences on her as a woman; and (4) a lifetime of courage and dedication. Examples of work which was in advance of psychology included work in early intervention with low-income children, an emphasis on the use of scientific experimental methodology in field research, an eclectic approach which crossed disciplinary boundaries, a consultative approach to school psychology, and the inclusion of affective and cognitive education in inter-     

A Local Connectionist Account of Consonant Harmony in Child Language

This study represents an attempt to sketch a processing model of phonological development in children acquiring their first language. The investigation is framed within a local connectionist network in which activation spreads between levels and inhibition within levels. Three ways are focused on in which an emergent processing system may diverge from a fully developed one—hypoactivation (too little activation due to underdeveloped links), hyperactivation (too much activation due to overloaded links) and impaired self‐inhibition. With a view to determining how children's productions relate to these three “error mechanisms,” one widespread phonological process, consonant harmony, is subjected to examination. Hypoactivation is found to capture the great majority of harmonic patterns. Hyperactivation and impaired self‐inhibition play a more marginal role and are only needed to account for exceptional cases of harmony. The feasibility of the psycholinguistic model is demonstrated with the help of computer simulations that were run with noise on both fully developed and developing networks. The model makes a number of predictions including the claim that difficult sounds are acquired in coda positions first.
