Individual differences in attention control and the processing of phonological contrasts in a second language.

This study investigated attention control in L2 phonological processing from a cognitive individual differences perspective, to determine its role in predicting phonological acquisition in adult L2 learning. Participants were 21 L1-Spanish learners of English, and 19 L1-English learners of Spanish. Attention control was measured through a novel speech-based attention-switching task.

Vocabulary Size Is a Key Factor in Predicting Second Language Lexical Encoding Accuracy.

This study investigates the relationship between the accuracy of second language lexical representations and perception, phonological short-term memory, inhibitory control, attention control, and second language vocabulary size. English-speaking learners of Spanish were tested on their lexical encoding of the Spanish /ɾ-r/, /ɾ-d/, /r-d/, and /f-p/ contrasts through a lexical decision task. Perception ability was measured with an oddity task, phonological short-term memory with a serial non-word recognition task, attention control with a flanker task, inhibitory control with a retrieval-induced inhibition task, and vocabulary size with the X_Lex vocabulary test.

The Hoosier Vocal Emotions Corpus: A validated set of North American English pseudo-words for evaluating emotion processing.

This article presents the development of the "Hoosier Vocal Emotions Corpus," a stimulus set of recorded pseudo-words based on the pronunciation rules of English. The corpus contains 73 controlled audio pseudo-words uttered by two actresses in five different emotions (i.e.

Diminished Neural Responses to Emotionally Valenced Facial Stimuli: A Potential Biomarker for Unemotional Traits in Early Childhood.

Callous-unemotional (CU) traits are characterized by deficits in guilt/empathy, shallow affect, and the callous and manipulative use of others. Individuals showing CU traits have increased risk for behavior problems and reduced responses to displays of distress in others. To explore how deficits in emotion-processing are associated with CU traits, the current study examined the association between callous-unemotionality and a neural index of facial emotion processing, using the event-related potential technique in a group of 3-5 year olds.

The Effect of Orthography on the Lexical Encoding of Palatalized Consonants in L2 Russian.

The current study investigated the potential facilitative or inhibiting effects of orthography on the lexical encoding of palatalized consonants in L2 Russian. We hypothesized that learners with stable knowledge of orthographic and metalinguistic representations of palatalized consonants would display more accurate lexical encoding of the plain/palatalized contrast. The participants of the study were 40 American learners of Russian.

Reduced neural responses to vocal fear: a potential biomarker for callous-uncaring traits in early childhood.

Objective: Callous-unemotional (CU) traits are characterized by a lack of guilt and empathy, and low responsiveness to distress and fear in others. Children with CU traits are at-risk for engaging in early and persistent conduct problems. Individuals showing CU traits have been shown to have reduced neural responses to others' distress (e.

Bimodal bilingualism as multisensory training?: Evidence for improved audiovisual speech perception after sign language exposure.

The aim of the present study was to characterize effects of learning a sign language on the processing of a spoken language. Specifically, audiovisual phoneme comprehension was assessed before and after 13 weeks of sign language exposure. L2 ASL learners performed this task in the fMRI scanner.

Modality-specific processing precedes amodal linguistic processing during L2 sign language acquisition: A longitudinal study.

The present study tracked activation pattern differences in response to sign language processing by late hearing second language learners of American Sign Language. Learners were scanned before the start of their language courses. They were scanned again after their first semester of instruction and their second, for a total of 10 months of instruction.

Modality-independent neural mechanisms for novel phonetic processing.

The present study investigates whether the inferior frontal gyrus is activated for phonetic segmentation of both speech and sign. Early adult second language learners of Spanish and American Sign Language at the very beginning of instruction were tested on their ability to classify lexical items in each language based on their phonetic categories (i.e.

The role of the striatum in phonological processing: evidence from early stages of Huntington's disease.

The linguistic role of subcortical structures such as the striatum is still controversial. According to the claim that language processing is subdivided into a lexical memory store and a computational rule system (Pinker, 1999) several studies on word morphology (e.g.
