Investigating instances where lexical selection fails can lead to deeper insights into the cognitive machinery and architecture supporting successful word retrieval and speech production. In this paper, we used a multiplex lexical network approach that combines semantic and phonological similarities among words to model the structure of the mental…

This study aimed to explore the types of pronunciation errors that student interpreters make in pronouncing foreign Proper Nouns during English-Arabic and Arabic-English Liaison Interpreting, the pronunciation error strategies that students utilize when they encounter unfamiliar Proper Nouns in media discourse, and the factors that affect…

Four picture-description experiments investigated if syntactic formulation in language production can proceed with only minimal working memory involvement. Experiments 1-3 compared the initiation latencies, utterance durations, and errors for syntactically simpler picture descriptions (adjective-noun phrases, e.g., "the red book") to…

This study investigates children's acquisition of the distinction between direct speech (Elephant said, "I get the football") and indirect speech ("Elephant said that he gets the football"), by measuring children's interpretation of first, second, and third person pronouns. Based on evidence from various linguistic sources, we…

Through analyzing response latencies, errors, and self-repairs in Mandarin, this investigation explores how monolingual, bilingual, and trilingual adults process their speech production differently using cognitive control mechanisms. In this study we conducted two experiments involving speech production in Mandarin. In the two experiments, 81…

The current dissertation represents one of the first systematic studies of the distribution of speech errors within supralexical prosodic units. Four experiments were conducted to gain insight into the specific role of these units in speech planning and production. The first experiment focused on errors in adult English. These were found to be…

Syntactic structure has been considered an integral component of agreement computation in language production. In agreement error studies, clause-boundedness (Bock & Cutting, 1992) and hierarchical feature-passing (Franck, Vigliocco, & Nicol, 2002) predict that local nouns within clausal modifiers should produce fewer errors than do those within…

We examine the mechanisms that support interaction between lexical, phonological and phonetic processes during language production. Studies of the phonetics of speech errors have provided evidence that partially activated lexical and phonological representations influence phonetic processing. We examine how these interactive effects are modulated…

Certain ill-formed phonological structures are systematically under-represented across languages and misidentified by human listeners. It is currently unclear whether this results from grammatical phonological knowledge that actively recodes ill-formed structures, or from difficulty with their phonetic encoding. To examine this question, we gauge…

This study has investigated the interlanguage features in spoken language of four foreigner learners of Bangla. Data has been collected through interviews which were recorded and analyzed. The analysis of the respondents' language has been made in terms of phonetic, morphological and syntactic aspects. The language deviations may be attributed to…

In theories of spoken language production, the gestural code prescribing the movements of the speech organs is usually viewed as a linear string of holistic, encapsulated, hard-wired, phonetic plans, e.g., of the size of phonemes or syllables. Interactions between phonetic units on the surface of overt speech are commonly attributed to either the…

There is considerable evidence from psycholinguistics that first language listeners handle function words differently from content words. This makes intuitive sense because content words require the listener to access a lexical meaning representation whereas function words do not. A separate channel of processing for functors would enable them to…

Examined effects of limitations in processing resources on error detection in self-produced and other-produced speech by means of a dual task paradigm. A production experiment and a perception experiment were carried out. In both cases, the percentage of repaired errors was larger in the single task condition than in the dual task condition,…

Word substitution errors from a corpus of 2,400 French slips of the tongue were grouped into several categories: contaminational, semantic, formal, and mixed cases; substitutions of syntagmatic codependents also occurred. Semantic and formal substitutions involved a resemblance between target and error. All substitutions exhibited a strong degree…

This 21st annual progress report summarizes research activities on speech perception and spoken language processing carried out in the Speech Research Laboratory, Department of Psychology, Indiana University in Bloomington. As with previous reports, the goal is to summarize accomplishments during 1996 and 1997 and make them readily available. Some…
