Abstract

Abstract: The "wù xiàng" of "cow" in people's memory thinking is its physical form and attributes, rather than the "information" of "cow". Based on this cognitive psychological fact, the theory of cognitive wù xiàng psychology is established, and the hypothesis of memory wù xiàng（Object-Entity) is proposed: memory is the cognitive psychological experience of meta-representation formed by the brain's central nervous system processing biological electrical signals from peripheral systems through wù xiàng processing; wù xiàng have the same attributes as things in the world. The theoretical proof mainly comes from contemporary cognitive psychology experiments and brain imaging research results. 
Cognitive psychology divides memory into nine types: short-term memory (sensory memory: auditory-visual memory, image memory), long-term memory, working memory, episodic (scene) memory, semantic memory, imagery memory, declarative memory, procedural memory, implicit memory, etc. They belong to different brain functional areas. According to the hypothesis of memory representation, all the content attributes of memory are represented by objects, and the cognitive psychological experience of memory content is also represented by objects. Only object-based memory can effectively explain the content of memory and closely link with knowledge application. The hypothesis of memory representation has been proven by a large number of cognitive psychological experiments, such as object shape processing and recognition in visual striate cortex and association cortex, face agnosia, cortical color blindness, visual agnosia, motor agnosia, word processing, psychological scanning, mirror (object) neurons, etc., all of which confirm the object processing and memory functions of the brain center. Neurons in different functional areas of the brain center have different functional characteristics, completing different types of object processing tasks, recognizing, interpreting, analyzing, organizing, and integrating sensory information to form the object representation process of neural consciousness material, forming the psychological experience of memory for things. For example, written objects are stored in the visual cortex and Broca's area, spoken objects are stored in the auditory cortex and Wernicke's area, and semantic objects are stored in the hippocampus and various cortical areas. 
According to the semantic wù xiàng hypothesis, semantic memory is also wù xiàng memory. People learn and understand the ways and processes of semantic wù xiàng through language, indirectly recognizing the world and bringing about knowledge increment. Under the guidance of purpose, the brain's central nervous system integrates, transforms, reconstructs, stores, or retrieves perceptual and semantic wù xiàng content, constituting all memory content and forming wù xiàng knowledge. The representation and retrieval of images in memory can activate relevant brain neural networks, enabling us to experience previously experienced sensations, situations, and semantic events, generating wù xiàng thinking, decision-making, and problem-solving. Language communication is merely a tool for expressing or recording image knowledge. Language thinking is essentially the retrieval and statement of wù xiàng thinking content in memory. Human behavior is guided and determined by the structural content of object wù xiàng and event wù xiàng in memory thinking.
