Aspects of the Theory of Comprehension, Memory and Attention

This paper proposed a two-stage model to capture some basic relations between attention, comprehension and memory for sentences. According to the model, the first stage of linguistic processing is carried out in short-term memory (M 1 ) and involves a superficial analysis of semantic and syntactic features of words. The second stage is carried out in long-term memory (M 2 ) and involves application of transformational rules to the analyses of M 1 so as to determine the deep or underlying relations among words and phrases. According to the theory, attention is an M 2 process: preliminary analyses by M 1 are carried out even for unattended inputs, but final analyses by M 2 are only carried out for attended inputs. The theory was shown to be consistent with established facts concerning memory, attention and comprehension, and additional support for the theory was obtained in a series of dichotic listening experiments.
