Several studies have shown that concepts spread activation to words of both of a bilingual's languages. Therefore, a central issue that needs to be clarified is how a bilingual manages to restrict his speech production to a single language. One influential proposal is that when speaking in one language, the other language is inhibited. An…

We tested a cue-based retrieval model that predicts how similarity between discourse entities influences the speaker's choice of referring expressions. In Experiment 1, speakers produced fewer pronouns (relative to repeated noun phrases) when the competitor was in the same situation as the referent (both on a horse) rather than in a different…

This study investigated the nature of the retrieval architecture of Semitic morphemic entities in word production in Hebrew, a language with a non-concatenated morphology. By taking advantage of the potential for dissociation of form and meaning in Hebrew, we explored the relative contribution of word-form and semantics to morphological…

The role of interference as a primary determinant of forgetting in memory has long been accepted, however its role as a contributor to poor comprehension is just beginning to be understood. The current paper reports two studies, in which speed-accuracy tradeoff and eye-tracking methodologies were used with the same materials to provide converging…

The research presented here uses theoretical constructs of formal syntax to account for performance data in agreement production. The phenomenon examined is object interference in French, i.e., incorrect agreement of the verb with the object. In the first experiment, interference is shown to occur in object relative clauses despite the absence of…

Directed forgetting and prospective memory methods were combined to examine differences in the control of memory access. Between studying two lists of target words, participants were either instructed to forget the first list, or to continue remembering the first list. After study participants performed a lexical decision task with an additional…

This article presents four experiments that tested predictions of SOB (Serial Order in a Box), an interference-based theory of short-term memory. Central to SOB is the concept of novelty-sensitive encoding, which holds that items are encoded to the extent that they differ from already-encoded information. On the additional assumption that…

Most current models of language production assume that information about gender is selected only in phrasal contexts, and that the phonological form of a noun can be accessed without selecting its syntactic properties. In this paper, we report a series of picture-word interference experiments with Italian-speaking participants where the…

The role of interference effects in sentence processing has recently begun to receive attention, however whether these effects arise during encoding or retrieval remains unclear. This paper draws on basic memory research to help distinguish these explanations and reports data from an experiment that manipulates the possibility for retrieval…

The process of naming an exception word prime (e.g., PINT) delays subsequent naming of a nonrhyming regular-inconsistent word body neighbor target (e.g., TINT). Both an activation account (Taraban & McClelland, 1987) and a learning account (Burt & Humphreys, 1993) have been offered to explain this interference effect. We investigated how long…

Bloem and La Heij (2003) reported that in a word-translation task context words induce semantic interference whereas context pictures induce semantic facilitation. This finding was accounted for by a model of lexical access in which: (a) semantic facilitation is localized at the conceptual level, (b) semantic interference is localized at the…

Single-task and dual-task versions of verbal and spatial serial order memory tasks were administered to 120 students tested for working memory capacity with four previously validated measures. In the dual-task versions, similarity between the memory material and the material of the secondary processing task was varied. With verbal material, three…

Four eye-tracking experiments examined lexical competition in non-native spoken-word recognition. Dutch listeners hearing English fixated longer on distractor pictures with names containing vowels that Dutch listeners are likely to confuse with vowels in a target picture name ("pencil," given target "panda") than on less confusable distractors…
