Abstract Objective To compare performance on EC301 battery calculation task between aphasic subjects and normal controls of the same sex, age, and education. Method Thirty-two aphasic patients who had suffered a single left hemisphere stroke were evaluated. Forty-four healthy volunteers were also selected. All subjects underwent a comprehensive arithmetic battery to assess their numerical and calculation skills. Performances on numerical processing and calculation tasks were then analyzed. Results Aphasic individuals showed changes in their ability to perform numerical processing and calculation tasks that were not observed in the healthy population. Conclusion Compared with healthy subjects of the same age and education level, individuals with aphasia had difficulty performing various tasks that involved numerical processing and calculation.

Objetivo Comparar o desempenho em tarefas de cálculo através da bateria EC301 entre sujeitos afásicos e indivíduos normais pareando as variáveis sexo, idade e educação.Método Foram avaliados 32 pacientes afásicos que sofreram lesão em hemisfério esquerdo único, concomitantemente com quarenta e quatro voluntários saudáveis. Todos foram submetidos a uma bateria de aritmética abrangente para avaliar habilidades numérica e de cálculo.Resultados Os indivíduos afásicos apresentaram alterações no processamento numérico e tarefas de cálculo que não foram observadas na população saudável. Conclusão Pacientes afásicos apresentam dificuldades para executar tarefas que envolvem processamento numérico e de cálculo em comparação com indivíduos saudáveis da mesma idade e escolaridade.
