Abstract
The purpose of this study was to design a short-term memory test, to describe quantitative performance in typically language developing children and to verify the relationship between the non-words repetition and oral phonological measure. The participants included 136 typically language developing children aged from 3 years to 6 years and 11 months old in this study, who were evaluated. The test consisted of 40 non-words of one, two, three, and four syllables. The subjects' repetitions were transcribed and the number of right answers was calculated for each age range. The effect of age was observed in the test, as well as the effect of length, only for disyllabic non-words. The performance in the non-word repetition task showed correlation with the oral phonology measure. The test designed in this research was able to verify the short-term memory in typically language developing children and the results showed correlation between this memory and phonological performance.
Highlights
The development of phonological short-term memory (PSTM) is essential for the development of child language, allowing the recollection and repetition of past events in the absence of their stimuli, acquisition of new knowledge, and integration of information[1]
The repetition of non-words (RNW) represents a sensitive measurement of the storage capacity of this memory in children aged less than six years old, i.e., in English and Spanish speakers[6,7]
The use of pseudowords facilitates their storage in PSTM, because of the phonological and/or morphological association with real words that exist in the studied language
Summary
The development of phonological short-term memory (PSTM) is essential for the development of child language, allowing the recollection and repetition of past events in the absence of their stimuli, acquisition of new knowledge, and integration of information[1]. This memory is in charge of storing and manipulating the necessary information to perform complex cognitive operations, such as learning, language understanding, and reasoning[2]. The repetition of non-words (RNW) assesses the capacity of temporary phonological storage of PSTM[4]. The use of pseudowords facilitates their storage in PSTM, because of the phonological and/or morphological association with real words that exist in the studied language
