JARAMILLO, Janeth Hernández; AVENDANO CALDERON, Angélica  e  ROJAS RINCON, Juliana. Effect of lexical and syllable frequency in anomic aphasia. Rev. Cienc. Salud [online]. 2012, vol.10, n.3, pp.337-346. ISSN 1692-7273.

Objective: this study compares the performance of two groups of participants with and without aphasia anomic in a lexical decision tasks (LDT) and spelling, in relation to the effect of the variables of word frequency and syllable. Materials and methods: a prospective study with a 2x2x2 design, which administered the LDT, in which each she/he had to decide if it was a real Spanish word or not, pressing one of two keys. To the task of spelling, they had to spell orally each of words presented auditorily. Results: It was found that in the LTD, the experimental group made more errors in the high-frequency stimuli syllable while the control group had more errors in the low-frequency syllables. In terms of reaction times was evident that the experimental group took longer to solve the task than the control group. The spelling task performance showed no difference in groups or conditions (lexical frequency and syllable). Conclusions: similar than other researches in normalized population, the results of this study demonstrate the effect of lexical frequency facilitation and inhibition that generates high syllable frequency.
