Previous issue date: 2012-09-12 / This dissertation is composed by two empirical sections, organized as two independent scientific papers. The first paper utilized a procedure which is similar to the DRM (Deese- Roediger-McDermott), tipically related to the research in false memory. Eight sets of thematically associated pictures were selected from the International Affective Picture System (IAPS). Half of the sets were negative valenced, while the other half were positively valenced; all the sets were highly arousing. 94 undergraduate students answered to a recognition test. Negative valenced items elicited higher proportions of both true and false memories. The results demonstrate the utility of the visual DRM to the study in the false memory research field, a procedure which is still poorly used in Brazil. In the second paper we investigated the influence of contextual cues on both memory performance and response confidence levels. Sets of negative and neutral words were selected from the Brazilian version of the Affective Norms for English Words (ANEW). 35 undergraduate students answered to a recognition test, where cues indicated the likely status of the upcoming word. Valid cues heightened proportions of both hits and correct rejections, in contrast to invalid cues. We found no influence of cues validity on the response confidence levels for hits. However, invalid cues decreased confidence on correct rejections. Negative and neutral items were similarly influenced by the cues validity. The results presented in the second paper demonstrate the influence of contextual cues on memory judgments / A presente disserta??o ? constitu?da por dois estudos emp?ricos apresentados na forma de artigos cient?ficos independentes. No Estudo I, utilizou-se um procedimento similar ao DRM (Deese-Roediger-McDermott), tipicamente relacionado ? pesquisa em falsas mem?rias. Foram selecionados oito conjuntos de imagens tematicamente associadas extra?das do International Affective Picture System (IAPS), metade com val?ncia emocional negativa e metade com val?ncia emocional positiva, ambos alertantes. Um teste de reconhecimento foi administrado em uma amostra de 94 estudantes universit?rios. Itens de val?ncia emocional negativa eliciaram maiores propor??es tanto de falsas mem?rias quanto de mem?rias verdadeiras. Dessa forma, os resultados demonstram a efetividade do DRM visual para o estudo das falsas mem?rias, procedimento ainda em desuso no Brasil. O Estudo II investigou a influ?ncia de pistas contextuais externas no desempenho e nos n?veis de confian?a na resposta, o que est? relacionado ? pesquisa em conformidade de mem?ria. Foram utilizados conjuntos de palavras de val?ncia emocional negativa e neutra extra?dos da vers?o brasileira do Affective Norms for English Words (ANEW). 35 participantes responderam a um teste de reconhecimento, durante o qual eram apresentadas pistas indicativas do prov?vel status da palavra. Observou-se que pistas v?lidas aumentaram as propor??es de acertos e de rejei??es corretas de itens novos, em compara??o a pistas inv?lidas. N?o houve influ?ncia da validade das pistas nos n?veis de confian?a para acertos; por?m, pistas inv?lidas proporcionaram um decr?scimo na confian?a nas rejei??es corretas. Itens de val?ncia emocional negativa e neutra foram afetados de forma similar pela validade das pistas. Os resultados apresentados no Estudo II demonstram a influ?ncia exercida por informa??es externas durante julgamentos de mem?ria
