When language learners are exposed to inconsistent probabilistic grammatical patterns, they sometimes impose consistency on the language instead of learning the variation veridically. The authors hypothesized that this regularization results from problems with word retrieval rather than from learning per se. One prediction of this, that easing the…

Blissymbols were learned significantly faster than manual signs, particularly in early learning trials. Results are discussed in terms of the memory requirements of the two systems. (Author/JDD)
