Event-related potential (ERP) studies have shown that emotional stimuli elicit greater amplitude late positive-polarity potentials (LPPs) than neutral stimuli. This effect has been attributed to arousal, but emotional stimuli are also more semantically coherent than uncategorized neutral stimuli. ERPs were recorded during encoding of positive,…

The paper describes the performance of three children with specific visuospatial working memory (VSWM) impairments (Study 1) and three children with visuospatial (nonverbal) learning disabilities (Study 2) assessed with a battery of working memory (WM) tests and with a number of school achievement tasks. Overall, performance on WM tests provides…

Thirty-six healthy participants received a discrimination learning task requiring the identification of a relevant stimulus dimension. After successful learning, the relevant dimension was shifted unannounced. All exemplars of the two dimensions presented after the shift were novel, implying a "total change" design. In three experimental…

It is commonly observed that "tone deaf" individuals are unable to hear the beat of a tune, yet deficits on simple timing tests have not been found. In this study, we investigated rhythm processing in nine individuals with congenital amusia ("tone deafness") and nine controls. Participants were presented with pairs of 5-note sequences, and were…

The present study investigated the possible role of ceiling effects in producing laterality effects of small magnitude in dichotic emotion detection. Twenty two right-handed undergraduate students participated in the present experiment. They were required to detect the presence of a target emotion in the expressions tones of happiness, sadness,…

Previous studies have demonstrated the sensitivity of chimpanzees to facial configurations. Three studies further these findings by showing this sensitivity to be specific to second-order relational properties. In humans, this type of configural processing requires prolonged experience and enables subordinate-level discriminations of many…

One hypothesis holds that bilingual children's cross-linguistic transfer occurs in spontaneous production when there is structural overlap between the two languages and ambiguity in at least one language (Dopke, 1998; Hulk and Muller, 2000). This study tested whether overlap/ambiguity of adjective-noun strings in English and French predicted…

This study examines growth rates in vocabulary over an academic year for 150 Latino English language learners. In October, February, and June of kindergarten, participants completed standardized measures of receptive and expressive vocabulary. Before the second and third assessments, a third of the children watched Arthur three times a week during…

This study examined sentence processing in emergent bilingual children and young adults in both English (second language -- L2) and Spanish (first language -- L1). One hundred participants from five different age groups (5;4-7;11, 8;0-10;11, 11;2-13;11, 14;0-16;8 years, and college-age adults) participated in this study. An online sentence…

The degree to which native and non-native readers interpret English sentences incrementally was investigated by examining plausibility effects on reanalysis processes. Experiment 1 required participants to read sentences word by word and to make on-line plausibility judgements. The results showed that natives and non-natives immediately computed…

Recent work in the bilingual literature suggests that naming pictures in a second language (L2) differs from naming pictures in the first language (L1) because of effortful lexical retrieval. his finding has received some support in the neuroimaging literature (De Blesser et al., 2003). In the current study, twelve Spanish-English bilinguals, who…

This contribution discusses findings and hypotheses from empirical data of naturally-occurring codeswitching. The discussion is framed by some comparisons of the approaches of contact linguists and psycholinguists to bilingual production data. However, it emphasizes the relevance of naturally-occurring codeswitching to the theoretical questions…

Phonological encoding is the process by which speakers retrieve phonemic segments for morphemes from memory and use the segments to assemble phonological representations of words to be spoken. When conversing in one language, bilingual speakers have to resist the temptation of encoding word forms using the phonological rules and representations of…

Bilingual speech requires that the language of utterances be selected prior to articulation. Past research has debated whether the language of speaking can be determined in advance of speech planning and, if not, the level at which it is eventually selected. We argue that the reason that it has been difficult to come to an agreement about language…

In this article we discuss different views about how information flows through the lexical system in bilingual speech production. In the first part, we focus on some of the experimental evidence often quoted in favor of the parallel activation of the bilinguals' two languages from the semantic system in the course of language production. We argue…
