Negation is a unique and fascinating property of human language which has been given extensive theoretical and typological treatment. One categorization divides negation use into metalinguistic negation and descriptive negation (Horn, 1985). Descriptive negation (DN) is the truth-functional semantic operator which has received the most attention…

Carol Stoel-Gammon has made a real contribution in bringing together two fields that are not generally jointly addressed. Like Stoel-Gammon, we have long focused on individual differences in phonological development (e.g. Vihman, Ferguson & Elbert, 1986; Vihman, Boysson-Bardies, Durand & Sundberg, 1994; Keren-Portnoy, Majorano & Vihman, 2008). And…

This study examined the second language (L2) development of adult learners of Spanish at three levels of proficiency during and after a semester of instruction. A fundamental goal was to identify cognitive and psychosocial individual differences (IDs) that can explain between-learner variation over time in order to expand our understanding of the…

Suggests that Goad & Ingram's (1987) argument in favor of a cognitive model of phonological development failed to recognize the uniqueness of each individual's neural and vocal structures, ignored documented variability in the phonetic patterns of prelexical infants, and inexplicably assumed that inter-child variability implied the operation of…

A variable rule of /s/ deletion that operates in many varieties of Spanish is examined. A descriptive apparatus is posited that may be helpful in systematizing quantitative data from studies of phonological variability. Empirical data from the speech of informants show that ordering relationships among constraints on variable phonological rules…

Finds significant correlations between scores on vocabulary tests and tests of syntax and morphology, suggesting two major second language learning factors (grammar and vocabulary/phonological ability). Relates these results to hypotheses concerning individual differences in strategies of first and second language learning. (Author/RL)

The phonemic inventories of 30 children (aged 3;4-5;7) with phonological delays were examined in terms of featural distinctions to address universal vs. individual accounts of acquisition. Phonetic inventories of the same children were also identified for comparison purposes. (Contains 40 references.) (JL)

The current study attempts to differentiate effects of phonotactic probability (i.e. the likelihood of occurrence of a sound sequence), neighbourhood density (i.e. the number of phonologically similar words), word frequency, and word length on expressive vocabulary development by young children. Naturalistic conversational samples for three…

Purpose: Research examining the relationship between spontaneous and imitated productions for phonological analysis has indicated that the inclusion of imitated productions may overestimate children's phonological abilities. Previous research in this area has included only English-speaking children. The purpose of this study was to determine what,…

Describes the presence of a phonological selection strategy and consonant harmony rule in one child's developing phonological system. Evidence suggests that this constant harmony constraint operated across morpheme boundaries, causing a delay in the onset of two-word utterances and influencing the selection of words that could occur in word…

Review research on foreign language aptitude and its measurement prior to 1990. Describes research areas in the 1990s, including affective variables, language learning strategies, learning styles as contributors to aptitude and aptitude as a cognitive construct affected by language variables. Reviews research on individual differences and the…

Research reports included in this volume of working papers in linguistics are: "Perception of Consonant Clusters and Variable Gap Time" (Mike Cahill); "Near-Merger in Russian Palatalization" (Erin Diehm, Keith Johnson); "Breadth of Focus, Modality, and Prominence Perception in Neapolitan Italian" (Mariapaola…

Drawing on recent psychological and neurological research on how individual differences might interact with learning a particular language, the study examines how psycholinguistic research and theory can help in assigning military personnel to language training and to a given language. Using the Defense Language Institute's Defense Language…
