1. Estudo comparativo do acesso semântico no processamento visual de palavras entre brasileiros monolíngues e chineses multilíngues falantes do português do Brasil como língua estrangeira = Comparative study of the semantic access in the visual processing of words between monolinguistic Brazilians and multilinguistic Chinese who speak Portuguese as a foreign language / Comparative study of the semantic access in the visual processing of words between monolinguistic Brazilians and multilinguistic Chinese who speak Portuguese as a foreign language
O priming semântico é uma forma de avaliar o processamento semântico de palavras. Se a semântica é um importante fator contribuinte no reconhecimento visual de palavras, surge a questão de se chineses multilíngues (mandarin como L1 e inglês como L2), que estão aprendendo o português como L3, podem se beneficiar do contexto semântico em tarefa de d

2. A imagem do Brasil no jornalismo estrangeiro
This study, part of the GELC Project _ Grupo de Pesquisa em Linguística de Corpus _ aimed at identifying images of Brazil in texts published in US and UK newspapers, that had been translated into Portuguese and printed in Brazilian online news services. An image is a representation of the country or aspects of it. Since there were no methods available to ad

3. Efeitos de priming semântico em tarefa de decisão lexical com diferentes intervalos entre estímulos / Semantic priming effect in a lexical decision task with different stimulus onset asynchrony
Esta dissertação buscou analisar o efeito de priming semântico em uma tarefa de decisão lexical. No estudo 1, comparou-se o efeito de priming semântico entre crianças e universitários em dois SOAs (250ms e 500ms). Os resultados mostraram que no SOA de 250ms, apenas as crianças tiveram efeito de priming semântico. Quando o SOA foi de 500ms, ambos gru

4. NEURAL AND COGNITIVE STUDIES OF THOUGHT DISORDER IN SCHIZOPHRENIA
Thought Disorder (TD) is one of the most striking features of schizophrenia and is manifested clinically as abnormal speech. Despite being a core feature of the illness very little is known of its pathophysiology. One model based on a series of word-pair priming studies formulates TD as a consequence of hyper activation of the semantic network. However, as w

5. Rebolar e requebrar, algo a mais do que dançar? : um estudo experimental sobre o acesso visual de verbos prefixados e pseudo-prefixados na lingua portuguesa
The aim of this dissertation is to experimentally study the lexical access of morphologically complex words, presented visually. The main question relates to how morphologically complex words ? especially prefixed verbs - are represented: are processing units in correspondence to a whole-word representation, or are they in correspondence to morphological con

6. The role of left prefrontal cortex in language and memory
This article reviews attempts to characterize the mental operations mediated by left inferior prefrontal cortex, especially the anterior and inferior portion of the gyrus, with the functional neuroimaging techniques of positron emission tomography and functional magnetic resonance imaging. Activations in this region occur during semantic, relative to no

7. Morphology and the internal structure of words
Morphology is the aspect of language concerned with the internal structure of words, and languages vary in the extent to which they rely on morphological structure. Consequently, it is not clear whether morphology is a basic element of a linguistic structure or whether it emerges from systematic regularities between the form and meaning of words. Here, we lo

8. Genetics of Event-Related Brain Potentials in Response to a Semantic Priming Paradigm in Families with a History of Alcoholism
Event-related brain potentials (ERPs) are altered in patients with a variety of psychiatric disorders and may represent quantitative correlates of disease liability that are more amenable to genetic analysis than disease status itself. Results of a genomewide linkage screen are presented for amplitude of the N4 and P3 components of the ERP, measured at 19 sc

9. Activation of the hippocampus in normal humans: a functional anatomical study of memory.
We studied regional cerebral blood flow using the H2(15)O method while normal subjects performed four similar tasks involving three-letter word beginnings (stems). Prior to each task, subjects studied a list of words. Local blood flow was then monitored during a 40-sec period while subjects (i) silently viewed word stems, (ii) completed stems to form the fir

10. Aging Influences the Neural Correlates of Lexical Decision but Not Automatic Semantic Priming
Human behavioral data indicate that older adults are slower to perform lexical decisions (LDs) than young adults but show similar reaction time gains when these decisions are primed semantically. The present study explored the functional neuroanatomic bases of these frequently observed behavioral findings. Young and older groups completed unprimed and primed

11. Theories of episodic memory.
Theories of episodic memory need to specify the encoding (representing), storage, and retrieval processes that underlie this form of memory and indicate the brain regions that mediate these processes and how they do so. Representation and re-representation (retrieval) of the spatiotemporally linked series of scenes, which constitute an episode, are probably
