20.500.12556/RUL-183660 So enote reprezentacijskega sistema v vidnem delovnem spominu objekti ali posamične vidne lastnosti? magistrsko delo Are the units of the respresentational system in visual working memory objects or individual visual features? Vidni delovni spomin je podsistem delovnega spomina, ki je odgovoren za vkodiranje, vzdrževanje in priklic vidnih informacij in je ključnega pomena za učinkovito kognitivno delovanje. Na področju vidnega delovnega spomina se veliko raziskav osredotoča na preučevanje njegove omejene kapacitete, pri čemer je eden izmed ciljev ugotoviti, kaj so osnovne enote shranjevanja. Zaključki raziskav na tem področju si niso enotni. Nekatere raziskave kažejo, da je osnovna enota shranjevanja posamična vidna lastnost, druge, da je to celoten vidni objekt, tretje pa da gre za kombinacijo posamičnih lastnosti in objektov. Cilj naše raziskave je bil to podrobneje preučiti z upoštevanjem teoretičnega modela dveh sistemov, ki predpostavlja, da je kapaciteta vidnega delovnega spomina omejena na dveh ravneh – z reprezentacijskim sistemom, ki je odgovoren za vzpostavljanje reprezentacij vidnih informacij, in aktivacijskim sistemom, ki je odgovoren za vzdrževanje reprezentacij vidnih informacij. V naši raziskavi je sodelovalo 64 udeležencev, ki so izvedli nalogo razpona vidnega delovnega spomina, v kateri so si morali zapomniti barve, oblike ali obe lastnosti vidnih objektov, prikazanih na eni ali obeh straneh vidnega polja. Primerjava ocenjene kapacitete delovnega spomina pri ločenem in integriranem prikazu barv in oblik v enostranskih in obojestranskih pogojih ter izpeljani indeksi so skladni z razlago, da je osnovna enota shranjevanja v reprezentacijskem sistemu integrirani objekt, medtem ko je osnovna enota shranjevanja v aktivacijskem sistemu posamična vidna lastnost. Naše ugotovitve predstavljajo nov vpogled v razumevanje omejene kapacitete vidnega delovnega spomina na dveh ravneh, saj z modelom dveh sistemov pojasnjujejo hkratno omejitev s številom integriranih objektov in posamičnih vidnih lastnosti, ter postavljajo nove smernice za nadaljnje raziskave. Visual working memory is a subsystem of working memory that is responsible for encoding, maintaining, and retrieving visual information and is critical for effective cognitive functioning. In the field of visual working memory, a lot of research focuses on studying its limited capacity, with one of the goals being to determine what are the basic units of storage. The conclusions of research in this area are not unanimous. Some studies suggest that the basic unit of storage is an individual visual feature, others that it is a visual object, and still others that it is a combination of individual features and objects. The aim of our research was to examine this in more detail, taking into account the theoretical model of two systems, which assumes that the capacity of visual working memory is limited at two levels – a representational system responsible for establishing representations of visual information and an activation system responsible for maintaining representations of visual information. 64 participants took part in our study, performing a visual working memory span task in which they had to remember the colors, shapes, or both characteristics of visual objects displayed on one or both sides of the visual field. The comparison of the estimated working memory capacity in separate and integrated display of colors and shapes in unilateral and bilateral conditions and the derived indices are consistent with the interpretation that the basic storage unit in the representation system is an integrated object, while the basic storage unit in the activation system is an individual visible feature. Our findings provide new insight into the understanding of the limited capacity of visual working memory at two levels, as the two-system model explains the storage limitation with the number of integrated objects and individual visible properties, and sets new guidelines for further research. delovni spomin Kognitivna znanost vidni delovni spomin reprezentacije vkodiranje vzdrževanje priklic reprezentacijski sistem aktivacijski sistem visual working memory representations encoding maintenance retrieval representational system activation system true false false A.
