Phonological short-term memory and phonological awareness in students from the Elementary School

To characterize and compare the performance of students at the beginning and at the end of the elementary school in Short-Term Phonological Memory (STPM) and Phonological Awareness (PA).

We assessed 80 students of both the genders who showed adequate linguistic and academic performance. The sample comprised 40 students in 1st grade and 40 in 5th grade from a public state school with mean age of 6.2 and 9.8 years, respectively. The STPM was assessed using a standardized test of Pseudoword Repetition. PA was assessed through a Sequential Assessment Test (CONFIAS).

No difference was found between the students of 1st and 5th years in STPM both in total score and concerning the similarity of the pseudowords. Regarding PA, there was a significant difference among the percentage distribution of correct answers in syllabic and phonemic tasks, and the students from 5th grade presented better performance.

At the beginning and at the end of the elementary school, there is no difference in STPM performance. On the other hand, there is difference in PA, which highlights the influence of schooling on PA development. The correlation between STPM and PA only in 5th-year students suggests that, at the beginning of literacy, STPM cannot be considered as a predictor to children's performance in PA. Nevertheless, as the schooling advances, there is influence of PA on STPM.
