Opakovanie viet a pracovná pamäť

Abstract

Z vy'skumov vyply'va, zě na u'lohe opakovanie viet sa neza'visle na sebe podiel'aju' procesy dlhodobej a kra'tkodobej pama¨ti. Multi-komponentovy' model pracovnej pama¨ti podl'a Baddleyho a Hitcha poskytuje vyhovuju'ci teoreticky' popis ako sa tieto procesy do u'lohy opakovania viet zapa'jaju'. Aby sme presku'mali vplyv jazykovy'ch znalostı' ulozěny'ch v dlhodobej pama¨ti na vy'- kon v u'lohe opakovania viet, pri sťatisticky kontrolovanom vplyve procesov kra'tkodobej pama¨ti, zadali sme participantom u'lohy na jazykove' znalosti, fonologicku' kra'tkodobu' pa- ma¨t'(fonologicku' slucˇku), komplexnu' kra'tkodobu' pama¨t'(centra'lnu exekutı'vu) a u'lohu opakovanie viet.

Previous studies have suggested that short-term and long-term memory processes in- dependently affect performance in the sentence-imitation task. The multi-component working memory model by Baddeley and Hitch offers a suitable theoretical description of how these processes contribute to this performance. In order to examine the influence of language knowledge located in the long-term me- mory on performance in the sentence-imitation task while statistically controlling for the influence of short-term memory, we assigned to our participants different tasks testing their language knowledge, phonological short-term memory (phonological loop), com- plex short-term memory (central executive) and the sentence-repetition task. Results from hierarchical linear regression yield significant contribution of the tasks testing language knowledge to explaining the variance in the sentence-imitation task, while controlling for the contributions from the phonological and complex short-term memory tasks. These results are in accordance with previous research and the theory of multi-component working memory. Keywords: working memory, episodic buffer, sentence imitation
