Beginning with the classic work of Shepard, Hovland, & Jenkins (1961), Type II visual patterns (e.g., exemplars are large white squares OR small black triangles) have held a special place in investigations of human learning. Recent research on Type II "linguistic" patterns has shown that they are relatively frequent across languages…

The present investigation seeks to determine whether and under what circumstances can adult bilinguals deploy segmentation strategies characteristic of their two languages, or of their dominant language. To that end, we inquired whether the context language employed during the segmentation experiment (i.e., the language in which participants…

Recent research has shown that speakers are sensitive to non-contrastive phonetic detail present in nonnative speech (e.g. Escudero et al. 2012; Wilson et al. 2014). Difficulties in interpreting and implementing unfamiliar phonetic variation can lead nonnative speakers to modify second language forms by vowel epenthesis and other changes. These…

One intriguing question in language research concerns the extent to which orthographic information impacts on spoken word processing. Previous research has faced a number of methodological difficulties and has not reached a definitive conclusion. Our research addresses these difficulties by capitalizing on recent developments in the area of word…

How do infants find the words in the speech stream? Computational models help us understand this feat by revealing the advantages and disadvantages of different strategies that infants might use. Here, we outline a computational model of word segmentation that aims both to incorporate cues proposed by language acquisition researchers and to…

This study compared segmental distribution patterns for consonants and vowels in English infant-directed speech (IDS) and adult-directed speech (ADS). A previous study of Korean indicated that segmental patterns of IDS differed from ADS patterns (Lee, Davis & MacNeilage, 2008). The aim of the current study was to determine whether such differences…

The Delay of Principle B Effect (DPBE) has been discussed in various studies that show that children around age 5 seem to violate Principle B of Binding Theory (Chomsky, 1981, and related works), when the antecedent of the pronoun is a name, but not when the antecedent is a quantifier. The analysis we propose can explain the DPBE in languages of…

Phonological awareness (PA) is the ability to analyze spoken language into its component sounds and to manipulate these smaller units. Literature review related to PA shows that a variety of factor groups play a role in PA in Mandarin such as linguistic experience (spoken language, alphabetic literacy, and second language learning), item type,…

We present the results from an experiment that tests the perception of English consonantal sequences by Korean speakers and we confirm that perceptual epenthesis in a second language (L2) arises from syllable structure restrictions of the first language (L1), rather than linear co-occurrence restrictions. Our study replicates and extends Dupoux,…

To measure the symmetry of adult categorical phoneme perception, 10 adult male undergraduate students enrolled in an introductory psychology class were the subjects for this study as part of their course requirements. The stimuli used in this study were prepared at Haskins Laboratories by means of a parallel resonance synthesizer and computer. The…

This paper demonstrates the qualitative differences between the long and short vowels of Navaho from spectrum analysis of the language made by the Kay Electric Sona-Graph. (CK)

Sentences were read by six informants to determine the presence or absence of /n/ in /nth/ sequences. The sentences contained seven different levels of juncture with /nth/ occurring in word final position, intervocalically, and across word boundaries, among other places. Dental coarticulation was not hindered by most junctures. (SC)

Variability is a term used to cover several types of phenomena in language sound patterns and in phonetic realization of those patterns. Variability refers to the fact that every repetition of an utterance is different, in amplitude, rate of delivery, formant frequencies, fundamental frequency or minor phase relationship changes across the sound…
