Abstract:
This paper demonstrates how phenomena such as the word-superiority effect, which we usually take as evidence for top-down processing, can be explained in terms of connectionist models with a simple bottom-up architecture. Even recent data from studies by Elman and McClelland which appears to provide categorical evidence of a top-down influence of lexical information on phonetic processing can be accounted for by bottom-up connectionist models. The apparent interaction between higher and lower level processes is a consequence of the learning mechanism rather than being due to any on-line interaction between different levels of processing. These bottom-up connectionist models cannot be considered to be simply implementations of classical information processing box models.
