The Study On Effects Of Working Memory And Domain Knowledge Of Teenagers On Memory Performance

Both domain knowlegde and working memory facilitate performance in many cognitive tasks.however,very little is known about the interplay between them. Taking working memory ,domain knowledge as targets to explore mental mechanism of cognition has become a leading theme of cognitive research.This study taking students from 13 to 18 with wide ranges of domain knowledge as subjiects to explore the role that working memory and domain knowledge play in domain_relevant(basketball)memory task and domain_inrelevant(tennis) memory task,define the relationship between working memory and domain knowledge and therefore has a comprehensive and systemanic knowledge of mental mechanism of cognition development.The research's results are as follows:1.teenagers'working memory capacity has notable age difference. Working memory capacity growth with age(13-18) in the form of precise growth functions.2. working memory capacity, domain knowledge and age all have positive effects on memory performance.high levels of working memory capacity and domain knowledge are associated with superior memory performance.3.The relationship between working memory capacity and memory performance does not change in different memory task. It suggeests that working memory capacity and domain knowledge may operate independently under certain conditions.However,there was a small but notable interaction between domain knowledge and working memory capacity in domain-relevant task: a high level of working memory capacity enhances the facilitative effect of domain knowledge on cognitive performance.4. there's no evidence that domain knowledge and age has significant interaction.
