Abstract

In a classic experiment, Saffran, Aslin, and Newport (1996)
used a headturn preference procedure to show that infants can
discriminate between familiar syllable sequences (“words”)
and new syllable sequences (“non-words” and “part-words”).
While several computational models have simulated aspects of
their data and proposed that the learning of transitional prob-
abilities could be mediated by neural-net or chunking mech-
anisms, none have simulated the absolute values of infants’
listening times in the different experimental conditions. In this
paper, we used CHREST, a model based on chunking, to sim-
ulate these listening times. The model simulated the fact that
infants listened longer to novel words (non-words and part-
words) than familiar words. While the times observed with the
model were longer than those observed with infants, we make
a novel finding with regard to phonological store trace decay.
We also propose how to modify CHREST to produce data that
fits closer to the human data.
