Ao longo de aproximados quarenta anos de pesquisas arqueológicas no Centro e Norte de Minas Gerais, nos quais os grafismos rupestres foram contemplados, criou-se um cenário de um quase contínuo de áreas pesquisadas. Nestas as pesquisas dos vestígios gráficos parietais foram organizados em conjuntos, utilizando-se das grandes unidades classificatórias usuais na Arqueologia, dialogando com os conceitos de estilo e tradição. Esta pesquisa comparou os conjuntos gráficos de algumas regiões do centro e norte de Minas Gerais a partir de análises tipológicas e de associação temática a fim de se discutir as atribuições dos conjuntos em categorias classificatórias amplas e o delineamento de possíveis territórios. Para tanto se utilizou de conjuntos de dados primários e secundários, os últimos disponíveis das dissertações, teses, artigos e acervos do Museu de História Natural da UFMG e de diálogos entre o conceito de estilo, e próprios da reflexão metodológica, buscando uma aproximação entre a produção bibliográfica arqueológica e antropológica. / In a forty years period of archeological researches in the Center and in the North of Minas Gerais, in which rock art was contemplated, a scenario of an almost uninterrupted researched areas was created. In these areas, the parietal graphics traces were organized in sets, using the great classificatory unities, usual in archaeology, communicating with the notions of style and tradition. This research compared the graphical sets of some regions of the north and center of Minas Gerais, making use of typological analyses and thematic associations, aiming to discuss the filiations of the sets in wide classificatory categories and the design of some possible territories. In order to achieve it, sets of primary and secondary data were utilized, the ones that are available in the dissertations, thesis, articles and collections of Museu de História Natural da Universidade Federal de Minas Gerais and in dialogs between concept and style, and others associated to the methodological reflection, sighting an approach between the anthropological and archaeological bibliographic production.

Die Auswahl eines passenden Wortes aus semantisch verbundenen Wettbewerbern ist eine wesentliche Funktion der Sprachproduktion. Neuere strittige Befunde scheinen traditionellen lexikalischen Selektionsmodellen zu widersprechen. Der swinging lexical network (SLN) Ansatz offeriert eine kompetitiven Bezugsrahmen, der spezifische Voraussetzungen formuliert, unter denen semantische Erleichterungs- als auch Interferenzeffekte in Bildbenennungsparadigmen beobachtet werden können. Diese spezifischen Voraussetzungen betreffen a) die Manipulation eines Trade-offs zwischen konzeptueller Erleichterung und lexikalischer Interferenz, b) das Ausmaß an lexikalischer Kohortenaktivierung und c) die flexible Anpassungsfähigkeit des Sprachproduktionssystems. Die Trade-off-Annahme wurde durch Einflüsse von Assoziationen auf die Benennungslatenz untersucht (Studie 1), wenn Stimuli im kontinuierlichen Benennungsparadigma in einer scheinbar zufälligen Reihenfolge benannt werden. Information über den Einfluss lexikalischer Kohortenaktivierung auf die Wortproduktion wurde durch Manipulation semantischer Distanz und durch Kombination des kontinuierlichen Benennungsparadigmas mit ereignis-korrelierten Potentialen (EKPs) gewonnen (Studie 2). Zur Überprüfung der Flexibilitätsannahme werden Benennungslatenzen von Homophonen mittels Bild-Wort-Interferenzparadigma untersucht, nachdem Versuchspersonen wiederholt linguistische Mehrdeutigkeit verarbeiten haben (Studie 3). Die Ergebnisse zeigen semantische Interferenzeffekte für assoziativ und für eng kategorial verbundene Stimuli im kontinuierlichen Benennungsparadigma (Studie 1 & 2) und Erleichterungseffekte für Homophone im PWI, nachdem das kognitive System sich auf Mehrdeutigkeit adaptiert hatte (Studie 3). Eng kategorial verbundene Stimuli modulierten EKP-Komponenten in der P1, zwischen 250 und 400 ms und im N400-Zeitfenster, welche mit Wortproduktions-prozessen in Verbindung gebracht werden. / The selection of an appropriate word from other meaning-related competitors is a main function of language production. Recent inconclusive findings have casted doubt about traditional lexical selection accounts. The swinging lexical network (SLN) account presents a competitive framework that formulates specific conditions under which semantic facilitation or interference effects can be observed in picture naming paradigms. These specific conditions concern a) the manipulation of the trade-off between conceptual facilitation and lexical interference, b) the extent of lexical cohort activation and c) the flexible nature of the language production system. The trade-off assumption was assessed by investigating the impact of associations on naming latencies in the continuous naming paradigm in which semantically related items are named within a seemingly random sequence (Study 1). Information for the understanding of lexical cohort activation on word production was obtained by manipulating semantic distance in the continuous naming paradigm combined with event-related potentials (ERP; Study 2). Aiming at testing the flexibility assumption, effects of unrelated meaning alternatives of homophones in a picture-word interference (PWI) paradigm were investigated, after participants repeatedly processed linguistic ambiguities (Study 3). Results show semantic interference for associates and for closely related category co-ordinates in the continuous naming paradigm (Study 1 & 2), and facilitation effects for homophone names in the PWI after the cognitive system adapted to the processing of linguistic ambiguities (Study 3). Closely related stimuli modulated ERPs in the P1, between 250 and 400 ms, and in the N400 time window, which are known to be associated with single word naming processes. These results support the SLN model and enhance the understanding of semantic and cognitive factors that shape the microstructure of language production.
