Objetivo: Pretende-se com este estudo verificar se existem diferenças no desempenho e no tempo de reação (TR) no processamento de palavras emocionais (positivas e negativas) e não emocionais (neutras) numa tarefa de leitura em voz alta e repetição, em participantes saudáveis e com afasia. Método: A amostra é constituída por 48 participantes saudáveis (18 homens e 30 mulheres; idade 59.71 ± 12.40; escolaridade 10.23 ± 4.46; 91.67% destros) e 46 com afasia (25 do sexo masculino e 21 do feminino; idade 65.28 ± 11.72; escolaridade 8.80 ± 3.94; 97.48% destros; tempo de evolução 22.95 ± 142.7 dias; QA=75.20% ± 10.98). Utilizaram-se listas de 60 palavras emocionais e não emocionais, controladas para o tipo, tamanho e frequência e mediu-se o desempenho e o TR. Resultados: Na leitura, as palavras positivas apresentaram globalmente um desempenho significativamente superior às neutras (p=.023). Relativamente ao TR, verificou-se igualmente uma vantagem das palavras positivas, com menores TR’s nas palavras positivas em relação às negativas e neutras no grupo com afasia (p<.001) e nas positivas em relação às negativas no grupo de controlo (p=.044). Não foram identificadas diferenças significativas na repetição. Conclusões: Verificou-se vantagem das palavras emocionais, particularmente as de valência positiva no processamento da linguagem em participantes saudáveis e com afasia vascular. O uso de palavras emocionalmente positivas poderá ter impacto nos processos de avaliação e intervenção terapêutica.
Purpose: The aim of this study is to see if there are differences in performance and reaction time (RT) in the processing of emotional (positive and negative) and non-emotional (neutral) words, in a read-aloud and repetition task, in healthy subjects and those with aphasia. Method: The sample consisted of 48 healthy subjects (18 males and 30 females; age 59.71 ± 12.40; education 10.23 ± 4.46; 91.67% right-handed) and 46 with vascular aphasia (25 males and 21 females; age 65.28 ± 11.72; education 8.80 ± 3.94; 97.48% right-handed; time post onset 22.95 ± 142.7 days; AQ=75.20% ± 10.98). Lists of 60 emotional and non-emotional words controlled for type, length and frequency were used and accuracy and reaction time (RT) were measured. Results: In reading, positive words performed significantly better overall than neutral words (p=.023). Regarding RT, positive words also showed an advantage, with lower RTs for positive words than for negative and neutral words in the aphasia group (p<.001) and for positive words than for negative words in the control group (p=.044). No significant differences were identified in repetition. Conclusions: An advantage was found for emotional words, particularly those with positive valence, in language processing in normal subjects and those with vascular aphasia. The use of emotionally positive words could have an impact on the assessment and therapeutic intervention processes.
