20.500.12556/RUL-161603 Individual differences in spatial working memory strategies differentially reflected in the engagement of control and default brain networks Spatial locations can be encoded and maintained in working memory using different representations and strategies. Fine-grained representations provide detailed stimulus information, but are cognitively demanding and prone to inexactness. The uncertainty in fine-grained representations can be compensated by the use of coarse, but robust categorical representations. In this study, we employed an individual differences approach to identify brain activity correlates of the use of fine-grained and categorical representations in spatial working memory. We combined data from six functional magnetic resonance imaging studies, resulting in a sample of (⁠women, years) healthy participants performing a spatial working memory task. Our results showed that individual differences in the use of spatial representations in working memory were associated with distinct patterns of brain activity. Higher precision of fine-grained representations was related to greater engagement of attentional and control brain systems throughout the task trial, and the stronger deactivation of the default network at the time of stimulus encoding. In contrast, the use of categorical representations was associated with lower default network activity during encoding and higher frontoparietal network activation during maintenance. These results may indicate a greater need for attentional resources and protection against interference for fine-grained compared with categorical representations. neurosciences functional magnetic resonance imaging fMRI short term memory spatial memory brain mental representations individual differences nevroznanost funkcijsko magnetnoresonančno slikanje fMRI delovni spomin prostorski spomin možgani miselne predstave medosebne razlike true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-12 13:53:33 2024-09-12 13:53:39 2024-09-18 13:52:15 0000-00-00 00:00:00 2024 0 0 16 str. iss. 8 Vol. 34 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 159.953.2:612.82 1460-2199 10.1093/cercor/bhae350 207256579 Purg_Suljic_Individual_differences_in_spatial_working_memory....pdf Purg_Suljic_Individual_differences_in_spatial_working_memory....pdf 1 0737073FE952A6930EBE7FFC6C5B06CB 46e2e305cbed6e1542fea1e958327deb60591ffe2834e7674ac7452c5dadf600 26a1a53a-70fe-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190567 https://academic.oup.com/cercor/article/34/8/bhae350/7745821 1 9cc4d8d4-70fd-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=190566 Filozofska fakulteta 0 0 0
