The artificial grammar learning paradigm is a classic method of investigating the influence of universal constraints on shaping learning biases on language acquisition. While this method has been used extensively by linguists to test theoretical claims in generative grammar, one of the most prevalent frameworks in language acquisition, several studies have questioned whether artificial grammar learning reflects language acquisition enough to allow us to use it to draw inferences about the validity of universal constraints, particularly those arising from phonetic naturalness. The current study tests whether artificial grammar learning shows the effect of one robust phonetic naturalness constraint: the restriction on nasal harmony patterns arising from the sonority hierarchy. Nasal harmony is of particular interest because it is one of the few types of harmony that occurs between consonants and vowels, which is an under-researched topic. The results, contrary to the skeptical concerns, showed that participants (n = 120) could learn an artificial grammar involving a natural pattern, but could not learn one corresponding to an arbitrary/phonetically unmotivated pattern in the same way or to the same degree. This study contributes epistemic support to the large body of work using artificial grammar experiments to test phonological operations. [ABSTRACT FROM AUTHOR]

A fundamental problem in spoken language is the duality between the continuous aspects of phonetic performance and the discrete aspects of phonological competence. We study 2 instances of this problem from the phenomenon of voicing neutralization and vowel harmony. In each case, we present a model where the experimentally observed continuous distinctions are linked to the discreteness of phonological form using the mathematics of nonlinear dynamics.

Why is it preferable to say "salt and pepper" over "pepper and salt?" Based on an analysis of 692 binomial tokens from online corpora, we show that a number of semantic, metrical, and frequency constraints contribute significantly to ordering preferences, overshadowing the phonological factors that have traditionally been considered important. The ordering of binomials exhibits a considerable amount of variation. For example, although "principal and interest" is the more frequent order, "interest and principal" also occurs. We consider three frameworks for analysis of this variation: traditional optimality theory, stochastic optimality theory, and logistic regression. Our best models—using logistic regression—predict 79.2% of the binomial tokens and 76.7% of types, and the remainder are predicted as less frequent—but not ungrammatical—variants.

The article discusses multi level Optimality Theory (OT) and the ways of dealing with stages in phonological processing. OT should aim at ways to incorporate multiple levels of phonological processing, rather than focus on retaining the single evaluation hypothesis. In an OT approach, the constraints responsible for preferred syllable content are active only at pre-phonetic levels of evaluation, whereas a constraint on segmental markedness, saying that consonants should be as consonantal as possible and therefore nonsonorant is active at the pre-phonetic, as well as at the phonetic level. The tools of OT seem particularly suited to give a representation of the conflict between markedness constraints with opposing output goals Aphasia, in this approach, comprises the lowering of faithfulness constraints at the affected level of processing. Language breakdown provides a window on the workings of the language system and linguistic theories should be able to deal with the view thus offered.

The article examines the role of lexical universals in the theory of the human language faculty. Several distinctions have been found between the knowledge of an individual language and the knowledge of design principles of language. However, various problems have been generated with regards to the degree of the specificity of writing which involves design principles. Furthermore, other factors have also been sought including the distributional patterns in languages, speculations on the development of ranks in folk botanical taxonomies as well as the determination of nomenclature universals for partonomies.
