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,…

Argues that the lexical production system takes a compositional approach to processing morphologically complex forms in cases of productive word formation even if the semantics of the word cannot be derived formally from the meaning of its constituents. Evidence is presented from a case of acquired naming impairment in a patient whose ability to…

In the past years, there have been an increasing number of instrumental investigations as to the nature of speech production errors, prompted by the concern that decades of transcription-based speech error data may be tainted by perceptual biases. While all of these instrumental studies suggest that errors are not, as previously thought,…

A number of researchers have suggested that formulaic sequences are stored and processed holistically (Altenberg, 1998; Raupach, 1984; Schmitt & Carter, 2004; Spottl & McCarthy, 2004). However, the evidence for this hypothesis has not been conclusive. The present study examined the representation and processing of formulaic sequences in two online…

In order to study the role of working memory in sentence formulation, we elicited errors of subject-verb agreement in spoken sentence completion, while speakers did or did not maintain an extrinsic memory load (a word list). We compared participants with low and high speaking spans (a measure of verbal working memory for sentence production). As…

Speech errors reveal the speaker's implicit knowledge of phonotactic constraints, both languagewide constraints (e.g., /K/ cannot be a syllable onset when one is speaking English) and experimentally induced constraints (e.g., /k/ cannot be an onset during the experiment). Four experiments investigated the acquisition of novel 2nd-order…

Summarizes recent empirical research in second language acquisition. Discusses relationship between age and second language learning, implications of invariant order of acquisition of morphemes obtained in various second language acquisition studies, and role of errors in second language acquisition. (Author/BK)

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…

Errors involving universal quantification are common in contexts depicting sets of individuals in partial, one-to-one correspondence. In this article, we explore whether quantifier-spreading errors are more common with distributive quantifiers each and every than with all. In Experiments 1 and 2, 96 children (5- to 9-year-olds) viewed pairs of…

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…

Shows that hesitation phenomena are intricately connected with propspective and retrospective speech production tasks and mark critical points in processing. Two major hesitation categories exist: stalls and repairs. Stalls head off errors and represent error-free output; repairs take care of errors already committed. English and German examples…

Demonstrates that a more direct cause of verbal slips is occasional noise or interference in the phonological encoding processes, with the associations provided by cognitive states (and verbal context) serving merely as reference information for the semantic phase of prearticulatory editing. Relates this to "Freudian slips." (JMF)

Reviews psycholinguistic theories on the relationship between structure and function in language production. Criticizes the theory that sentence structures are reducible to the general forces of cognition that drive interpretation and communication. Argues that syntactic structures are necessary elements in an explanation of language use. (FMW)

Environmentally contaminated speech errors (irrelevant words or phrases derived from the speaker's environment and erroneously incorporated into speech) are hypothesized to occur at a high level of speech processing, but with a relatively late insertion point. The data indicate that speech production processes are not independent of other…

Analysis of several types of faulty language selection in polyglots revealed that production errors were not a result of limited vocabulary or language deficiency but rather to interlingual code-switching based on the polyglot's differentiations between dominant language, foreign language, and weak language.
