Subcortical Preprocessing of Oral Language: A Holistic Model for Language Cognition.
George, Don
This paper considers the process by which humans are able to select from the complex string of sounds impinging on the ear and understand certain frequency combinations to be linguistic signals while other combinations are not. A brief review of the complex subcortical region, particularly the known but seldom studied reticular system, indicates the probability that prior to its assessment in the cerebral cortex, the signal is filtered and integrated into matrices or patterns. From this hypothesis, a model is presented suggesting the process by which a speech signal is integrated subcortically into a series of increasingly complex matrices before being transmitted to the cortex. The matrix form of the transmitted electric signal causes cortical neurons to fire simultaneously in bursts rather than resonate sequentially. The pattern of each burst will reflect the distinctive features carried in the matrix stimulus. With memory considered held in holistic patterns, or matrices, rather than as strings of energy frequencies, identification of the distinctive features of the fired pattern with the matrices of language elements held in cognitive memory forms the basic element in oral language cognition, identified here as a cogneme. Certain pedagogical implications are considered; for example, cross cultural programs and cross cultural exposure should be extended into all areas of education to include the variety of cultural differences in America.
