Title: [Formation of spatial short-term memory in 18-54-month old children]. Author: Dashniani MG, Chkhikvishvili NTs, Aragveli RI, Noselidze AG, Naneĭshvili TL. Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 2001; 51(3):315-9. PubMed ID: 11550638. Abstract: The development of the spatial short-term memory (SSTM) in children aged 18-54-months was assessed by performance of the inverted delayed-response task (IDR). A child perceived the localization of a target object in one of the two containers (left or right) situated on a table in front of the child. The distance between the containers was 30 cm. Then the child was escorted to the opposite side of the table so that the target object that was earlier in the left container seemed to be in the right one. After the rotation, in 74% of cases children at the age of 18-24-months failed to localize the object correctly despite the presence of various reference objects in the room. Percent of correct responses increased with age. Children aged 24-54-months performed the IDR better in the presence of reference objects than in their absence. The preschool children at the age of 48-54-months correctly localized the object in 70% of cases even in the absence of the experimental reference objects. The results of this experiment demonstrate the stages of the SSTM development in children.[Abstract] [Full Text] [Related] [New Search]
