habits of the second. In classroom practice, the principles of habit formation
and interference led to the use of pattern drills in the audio-lingual method of
second-language learning. On the basis of CA, difficult patterns were
predicted and consequently emphasised in the drills.
The comparison of the structures of languages continues to be a
respectable activity within contrastive linguistics and has come to be
conducted within the framework of transformational generative grammar. Its
status as a psychological approach to the investigation of the second-
language-acquisition process, however, fell into disrepute for several
reasons. One reason was the unfortunate association of CA with the
behaviourist view of language acquisition, an account whose theoretical
adequacy came to be seriously questioned, most notably by Chomsky
(1959). In our view, a more devastating reason was that CA fared quite
poorly once researchers, instead of relying on anecdotal impressions from
the classroom, began collecting data in more systematic ways (Oller &
Richards, 1973). From these data, analyses of learners’ errors soon showed
that a large proportion were not predictable on the basis of CA. In fact, many
of these errors, such as rule simplification (as in “Mommy eat maize”) and
overgeneralisation (as in “He writed me a letter”) exhibited a striking
resemblance to those made by children acquiring a first language. Moreover,
learners did not in fact make all the errors predicted by CA.
When the inadequacy of CA as a predictive model became apparent,
Wardhaugh (1970) drew the useful distinction between strong and weak
versions of the approach. The strong version claimed to predict errors, while
the weak version simply accounted for errors that occurred. CA survives only
in its weak form with an obvious shortcoming: it gives an incomplete
representation of the second-language-acquisition process since it can
account only for some, not all, of the errors.
Within a few years, the landscape changed considerably. In part this
was the result of a vast array of new materials from studies of much greater
depth than previously, in part from opening new topics to investigation.
About 25 years ago, much of this work crystallised in a radically different
approach to UG, the “Principles and Parameters” (P&P) framework, which
for the first time offered the hope of overcoming the tension between
descriptive and explanatory adequacy. This approach sought to eliminate
the format framework entirely, and with it, the traditional conception of rules
and constructions that had been pretty much taken over into generative
grammar. The new P&P framework led to an explosion of inquiry into
languages of the most varied typology, leading to new problems previously
not envisioned, sometimes answers, and the reinvigoration of neighbouring
disciplines concerned with acquisition and processing, their guiding
