Event-related brain potentials during natural speech processing: effects of semantic, morphological and syntactic violations / Angela D. FRIEDERICI in Cognitive Brain Research, 1-3 (October 1993)

Public ISBD [article]  inCognitive Brain Research > 1-3 (October 1993) . - p.183-192 Titre : Event-related brain potentials during natural speech processing: effects of semantic, morphological and syntactic violations Type de document : texte imprimé Auteurs : Angela D. FRIEDERICI, Auteur ; Erdmut PFEIFER, Auteur ; Anja HAHNE, Auteur Année de publication : 1993 Article en page(s) : p.183-192 Langues : Anglais (eng) Mots-clés : Event-related-potential N400 Auditory-word-processing Semantic-priming Syntactic-priming Index. décimale : PER Périodiques Résumé : The present study investigated different aspects of auditory language comprehension. The sentences which were presented as connected speech were either correct or incorrect including a semantic error (selectional restriction), a morphological error (verb inflection), or a syntactic error (phrase structure). After each sentence, a probe word was presented auditorily, and subjects had to decide whether this word was part of the preceding sentence or not. Event-related brain potentials (ERPs) were recorded from 7 scalp electrodes. The ERPs evoked by incorrect sentences differed significantly from the correct ones as a function of error type. Semantic anomalies evoked a ‘classical’ N400 pattern. Morphological errors elicited a pronounced negativity between 300 and 600 ms followed by late positivity. Syntactic errors, in contrast, evoked an early negativity peaking around 180 ms followed by a negativity around 400 ms. The early negativity was only significant over the left anterior electrode. The present data demonstrate that linguistic errors of different categories evoke different ERP patterns. They indicate that with using connected speech as input, different aspects of language comprehension processes cannot only be described with respect to their temporal structure, but eventually also with respect to possible brain systems subserving these processes.

Accessing and selecting word meaning in autism spectrum disorder / Lynnette M. HENDERSON in Journal of Child Psychology and Psychiatry, 52-9 (September 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-9 (September 2011) . - p.964-973 Titre : Accessing and selecting word meaning in autism spectrum disorder Type de document : texte imprimé Auteurs : Lynnette M. HENDERSON, Auteur ; Paula J. CLARKE, Auteur ; Margaret J. SNOWLING, Auteur Année de publication : 2011 Article en page(s) : p.964-973 Langues : Anglais (eng) Mots-clés : Language comprehension  ambiguity resolution  semantic priming  homonyms  poor comprehenders Index. décimale : PER Périodiques Résumé : Background:  Comprehension difficulties are commonly reported in autism spectrum disorder (ASD) but the causes of these difficulties are poorly understood. This study investigates how children with ASD access and select meanings of ambiguous words to test four hypotheses regarding the nature of their comprehension difficulties: semantic deficit, weak central coherence, reduced top-down control and inhibition deficit. Methods:  The cross-modal semantic priming paradigm was used. Children heard homonym primes in isolation or as final words in sentences biased towards the subordinate meaning and then named picture targets depicting dominant or subordinate associates of homonyms. Results:  When homonyms were presented in isolation, children with ASD and controls showed priming for dominant and subordinate pictures at 250ms ISI. At 1,000ms ISI, the controls showed dominant (but not subordinate) priming whilst the ASD group did not show any priming. When homonyms were presented in subordinate sentence contexts, both groups only showed priming for context-appropriate (subordinate) meanings at 250ms ISI, suggesting that context has an early influence on meaning selection. At 1,000ms ISI the controls showed context-appropriate (but not inappropriate) priming whereas the ASD group showed both appropriate and inappropriate priming. Conclusions:  Children with ASD showed intact access to semantic information early in the time course of processing; however, they showed impairments in the selection of semantic representations later in processing. These findings suggest that a difficulty with initiating top-down strategies to modulate online semantic processing may compromise language comprehension in ASD. Implications for intervention are discussed.

Atypical Lexical/Semantic Processing in High-Functioning Autism Spectrum Disorders without Early Language Delay / Yoko KAMIO in Journal of Autism and Developmental Disorders, 37-6 (July 2007)

In this study, we aimed to examine whether the automatic lexical/semantic aspect of language is impaired or intact in these population. Eleven individuals with Asperger’s Disorder (AS) or HFPDD-Not Otherwise Specified (NOS) and age-, IQ-, and gender-matched typically developing individuals performed a semantic decision task in four conditions using an indirect priming paradigm. Semantic priming effects were found for near-semantically related word pairs in the controls, whereas this was not the case in the AS or HFPDDNOS participants. This finding suggests similarities in the underlying semantic processing of language across PDD subtypes.

Atypical Social Modulation of Imitation in Autism Spectrum Conditions / Jennifer L. COOK in Journal of Autism and Developmental Disorders, 42-6 (June 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-6 (June 2012) . - p.1045-1051 Titre : Atypical Social Modulation of Imitation in Autism Spectrum Conditions Type de document : texte imprimé Auteurs : Jennifer L.

In the present study we subliminally primed high-functioning adults with ASC and age- and IQ-matched controls with either a pro- or non- social attitude. Following priming, an automatic imitation paradigm was used to acquire an index of imitation. Whereas imitation levels were higher for pro-socially primed relative to non-socially primed control participants, there was no difference between pro- and non- socially primed individuals with ASC. We conclude that high-functioning adults with ASC demonstrate atypical social modulation of imitation. Given the importance of imitation in social interaction we speculate that difficulties with the modulation of imitation may contribute to the social problems characteristic of ASC.

Context processing in adolescents with autism spectrum disorder: How complex could it be? / Dekel BEN-YOSEF in Autism Research, 10-3 (March 2017)  

Public ISBD [article]  inAutism Research > 10-3 (March 2017) . - p.520-530 Titre : Context processing in adolescents with autism spectrum disorder: How complex could it be? Type de document : texte imprimé Auteurs : Dekel BEN-YOSEF, Auteur ; David ANAKI, Auteur ; Ofer GOLAN, Auteur Article en page(s) : p.520-530 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  context processing  priming  central coherence  social cognition  complexity Index. décimale : PER Périodiques Résumé : The ability of individuals with Autism Spectrum Disorder (ASD) to process context has long been debated: According to the Weak Central Coherence theory, ASD is characterized by poor global processing, and consequently—poor context processing. In contrast, the Social Cognition theory argues individuals with ASD will present difficulties only in social context processing. The complexity theory of autism suggests context processing in ASD will depend on task complexity. The current study examined this controversy through two priming tasks, one presenting human stimuli (facial expressions) and the other presenting non-human stimuli (animal faces). Both tasks presented visual targets, preceded by congruent, incongruent, or neutral auditory primes. Local and global processing were examined by presenting the visual targets in three spatial frequency conditions: High frequency, low frequency, and broadband. Tasks were administered to 16 adolescents with high functioning ASD and 16 matched typically developing adolescents. Reaction time and accuracy were measured for each task in each condition. Results indicated that individuals with ASD processed context for both human and non-human stimuli, except in one condition, in which human stimuli had to be processed globally (i.e., target presented in low frequency). The task demands presented in this condition, and the performance deficit shown in the ASD group as a result, could be understood in terms of cognitive overload. These findings provide support for the complexity theory of autism and extend it. Our results also demonstrate how associative priming could support intact context processing of human and non-human stimuli in individuals with ASD.
