When the visual system is faced with conflicting or ambiguous stimulus information, visual perception fluctuates over time. We found that perceptual alternations are slowed when inducing stimuli move within the visual field, constantly engaging fresh, unadapted neural tissue. During binocular rivalry, dominance durations were longer when rival figures moved compared to when they were stationary...

Phonological alternations often serve to modify forms so that they respect a phonotactic restriction that applies across the words of language. Although it has long been assumed that an adequate theory of phonology should capture the connection between phonotactics and alternations, there is however, no psycholinguistic evidence that speakers actually do use a single mechanism for them both. In...

The voicing contrast is neutralized syllable and word finally in Dutch and German, leading to alternations within the morphological paradigm (e.g., Dutch 'bed(s)', be[t]-be[d]en, German 'dog(s)', Hun[t]-Hun[d]e). Despite structural similarity, language-specific morphological, phonological and lexical properties impact on the distribution of this alternation in the two languages. Previous acquis...

This study deals with a significant morphological difference between Latin and Romance, namely that the latter has pervasive patterns of root-allomorphy absent from the former. Of particular interest here is the emergence of such allomorphy correlated with arbitrarily intersecting parameters of person, number, tense and mood in the verb. The alternations in question are, initially, the predicta...

When two dissimilar stimuli are presented to the eyes, perception alternates between multiple interpretations, a phenomenon dubbed binocular rivalry. Numerous recent imaging studies have attempted to unveil neural substrates underlying multistable perception. However, these studies had a conceptual constraint: access to observers' perceptual state relied on their introspection and active report...

A common view in the phonological literature is that phonological alternations typically involve markedness reduction; that is, deviation from an input is basically characterized as a repair of a marked structure. Under the most extreme version of phonological theory, every output constraint is simply a reflection of a markedness hierarchy, meaning that all disparities between inputs and output...

Romanian phonology is shown to be subject to inflection dependence, a systematic restriction on phonological alternations. Inflection dependence means that segmental alternations are permitted in the derivatives of a lexeme only if certain inflected forms of that lexeme, its inflectional bases (Albright 2002), independently display the alternation. The study documents this pervasive constraint ...
