The Colour Superiority Effect And Information Retrieval Mode Of Feature Recognition In Object Visual Working Memory

The research of Visual Working Memory (VWM) is a hotspot of psychology, these research are mainly focus on the object information storage, however, research focus on recognition of object feature information is insufficient. To explore object feature recognition will contribute to our daily practice, and, it can offer us something enlightenment theoretically.First, object is consisted of different features (such as colour, form and pattern), these features offer direct clue to object recognition. Therefore, is there any difference in the recognition time during these features? To explore the recognition characteristic of each feature is necessary and helpful to sign and appearance design of industry production.Second, the theory of information retrieval in memory is mainly based on short-term memory study. The material in these research experiments is mostly about verbal, such as number and word, and, there is something defect in the display of memory items, which would have misled the research conclusion. To explore the mode of information retrieval in object VWM will promote the development of visual information retrieval theory.In this study, there are three features:colour, form and pattern, the aim is to explore the time difference of recognition of each feature in object VWM. The information retrieval mode during the recognition of object feature is also what we hope to find out. Besides, the relationship between characteristic of feature recognition time and the mode of information retrieval will be under discussion. To attain the anticipation, behavior experiment method of VWM study is adopted.The study show that:In the feature recognition of object VWM, the time of feature recognition is significant different, of the three features, the recognition time of colour is significant shorter than the other two features and the recognition time of form is a little shorter than pattern's (not significant), meanwhile, this difference is not affected by the number of object feature and the participation of cognition activity. When detect items is constant with the object information of VWM, the recognition time becomes longer with the number of object feaure increasing. When not, the time has nothing to do with the number of object feature and the location of each feature.The conclusion is as follow:Colour superiority effect is steadily exist in the process of object VWM feature recognition, it is conf cd by the time difference of feature recognition, which was already mentioned in the result. And also, there are two modes during the feature recognition process of object VWM, they are Parallel Processing Mode and Direct Access Model. when the detect item is constant with information in object VWM, features is recognized by Parallel Processing Mode, when not, features is recognized by Direct Access Mode...
