A functional neuroimaging study examined the long-term neural correlates of early adverse rearing conditions in humans as they relate to socio-emotional development. Previously institutionalized (PI) children and a same-aged comparison group were scanned using magnetic resonance imaging (fMRI) while performing an Emotional Face Go/Nogo task. PI showed heightened activity amygdala, region that supports emotional learning reactivity stimuli, corresponding decreases cortical regions support...
Significance Using functional MRI, we examined reading and speech perception in four highly contrasting languages: Spanish, English, Hebrew, Chinese. With three complementary analytic approaches, demonstrate that spite of striking dissimilarities among writing systems, successful literacy acquisition results a convergence the orthographic processing systems onto common network neural structures. These findings have major theoretical implication has evolved to be universally constrained by...
Abstract The N170 component of the event-related potential (ERP) reflects experience-dependent neural changes in several forms visual expertise, including expertise for words. Readers skilled writing systems that link characters to phonemes (i.e., alphabetic writing) typically produce a left-lateralized word forms. This study examined three Japanese scripts larger phonological units. Participants were monolingual English speakers (EL1) and native (JL1) who also proficient English. ERPs...
Recent research has shown that the degree to which speakers and listeners exhibit similar brain activity patterns during human linguistic interaction is correlated with communicative success. Here, we used an intersubject correlation approach in fMRI test hypothesis a listener's ability predict speaker's utterance increases such neural coupling between listeners. Nine subjects listened recordings of speaker describing visual scenes varied they permitted specific predictions. In line our...
Selective attention to speech versus nonspeech signals in complex auditory input could produce top-down modulation of cortical regions previously linked perception spoken, and even visual, words. To isolate such attentional effects, we contrasted 2 equally challenging active listening tasks, performed on the same stimuli (words overlaid with a series 3 tones). Instructions required selectively attending either (in service rhyme judgment) or melodic (tone-triplet matching). speech, relative...
A hallmark of categorical perception is better discrimination stimulus tokens from 2 different categories compared with token pairs that are equally dissimilar but drawn the same category. This effect well studied in speech and represents an important characteristic how phonetic form processed. We investigated brain mechanisms stop consonants using functional magnetic resonance imaging a passive short-interval habituation trial design (Zevin McCandliss 2005). The paradigm takes advantage...
Sensorimotor processing in children and higher-cognitive adults could determine how non-native phonemes are acquired. This study investigates age-of-acquisition (AOA) proficiency-level (PL) predict native-like perception of statistically dissociated L2 categories, i.e., within-category between-category. In a similarity task, participants rated the level between pairs English syllables from 1 (similar) to 4 (dissimilar). Early acquisition predicts accurate within-categorization high...
Abstract Drawing from a common lexicon of semantic units, humans fashion narratives whose meaning transcends that their individual utterances. However, while brain regions represent lower‐level such as words and sentences, have been identified, questions remain about the neural representation narrative comprehension, which involves inferring cumulative meaning. To address these questions, we exposed English, Mandarin, Farsi native speakers to language translations same stories during fMRI...
Mental and neural representations of words are at the core understanding cognitive mechanisms reading. Despite extensive studies, nature visual word representation remains highly controversial due to methodological limitations. In particular, it is unclear whether fusiform cortex contains only abstract orthographic representation, or represents both lower higher level orthography as well phonology. Using representational similarity analysis, we integrated behavioral ratings, computational...
A modified priming task was used to investigate whether skilled readers are able adjust the degree which lexical and sublexical information contribute naming. On each trial, participants named 5 low-frequency exception word primes or nonword before a target. The should have produced greater dependence on information, whereas information. Across 4 experiments, effects of lexicality, regularity, frequency, imageability were all modulated in predictable ways basis notion that directed attention...
Learning to read in any language requires learning map among print, sound and meaning. Writing systems differ a number of factors that influence both the ease rate with which reading skill can be acquired, as well eventual division labor between phonological semantic processes. Further, developmental disability manifests differently across writing systems, may related different deficits constitutive Here we simulate some aspects acquisition Chinese English using same model for systems. The...
Differences in how writing systems represent language raise important questions about whether there could be a universal functional architecture for reading across languages. In order to study potential differences the neural networks that support skill, we collected fMRI data from readers of alphabetic (English) and morpho-syllabic (Chinese) during two tasks. one, participants read short stories under conditions approximate natural reading, other, decided individual stimuli were real words...
Zebra finches (Taeniopygia guttata) learn a specific song pattern during sensitive period of development, after which changes little or not at all. However, recent studies have demonstrated substantial behavioral plasticity in behavior adulthood under range conditions. The current experiment examined adult zebra temporarily deprived auditory feedback by chronic exposure to loud white noise (WN). Long-term continuous WN resulted disruption similar that observed deafening. When was restored...
Very little is known about how auditory categories are learned incidentally, without instructions to search for category-diagnostic dimensions, overt category decisions, or experimenter-provided feedback. This an important gap because learning in the natural environment does not arise from explicit feedback and there evidence that systems engaged by traditional tasks distinct those recruited incidental learning. We examined with a novel paradigm, Systematic Multimodal Associations Reaction...
BACKGROUND: Neural systems show habituation responses at multiple levels, including relatively abstract language categories. Dishabituation - to non-habituated stimuli can provide a window into the structure of these categories, without requiring an overt task. METHODS: We used event-related fMRI design with short interval trials, in which trains were presented passively during 1.5 second intervals relative silence between clustered scans. Trains four identical (standard trials) and three...
