| Abstract: |
This thesis investigates the predictions of Barcroft’s type of processing-
resource allocation (TOPRA) model. The TOPRA model contends that in order to learn a second/foreign language word, one must complete three subprocesses. These are processing for form, processing for meaning, and form-meaning mapping. The model posits that corresponding amounts of one of these types of processing leads to corresponding amounts of learning. Thus, semantic processing will lead to the learning of meanings, while structural processing will lead to the learning of word forms. The model contends that human beings are limited capacity processers, so in learning a foreign language, excessive processing in one of these areas drains resources that could be used for processing and subsequent learning in other areas. Therefore, excessive semantic processing can be detrimental to learning the structural properties of a word during the initial stages of foreign language lexical acquisition. Indeed, the main thrust of Barcroft’s research in the area has been to demonstrate the detrimental effects of semantic processing. He has proposed that learners should not be forced to undertake activities involving semantic elaboration during the initial stages of learning new words. The series of studies conducted during the present thesis found some support for the predictions of the TOPRA model when Barcroft’s experimental paradigm was followed. However, at the same time, the studies here found many conflicting results to the predictions of the model. Therefore, the scope of the model seems to be limited. Furthermore, it is contended that multiple retrieval of words rather than the amount of their structural or semantic processing is a more important determinant of second language lexical acquisition. |
