Abstract

Psychological appearances perceive things in mind retained and reproduced image. It can well explain many of the operations process of the human impact on the learning ability of the human activity of thinking, memory capacity, and verbal ability, an important part of the structure of human intelligence, has an important significance of the human imagination, thinking and other higher mental activities . Similarly, object recognition is important for human survival ability is an important guarantee of human daily life. Every day we receive a lot of information from the environment, and in most cases we can understand these relates to the object recognition and identification information. Object recognition process may seem simple, but it is actually a fairly complex process. Visual information from the external world of three-dimensional objects, projected onto the observer on the retina to form a two-dimensional image that matches with the information in the memory, object recognition is on the basis of the two-dimensional image. The scientific results of testing the interaction between visual imagery and visual perception, promote or hinder the interaction process between the two to provide a lot of the basis for researchers to understand the relationship between representation and object recognition. However, it has not been studied in-depth discussion about the visual appearance of the object recognition impact. In addition, the study on the impact on the mental representation of object recognition is not sufficient. Object recognition and visual mental imagery are important for human survival ability is an important guarantee for the survival of human adaptability. Therefore, the interaction between human survival significance. The purpose of this study is to study the object recognition on the mental imagery generation and detection, the argument of the relationship between representation and object recognition. The appearance - graphic / word interference studies designed to explore the representation tasks carried out at the same time object recognition can influence the appearance of the generation and detection process, and object recognition is how to influence the appearance of the task. The studies were designed four experiments, both within-subject design. The experiment used a 2 (task type: left - right level of representation judgment task and long - wide representation judgment task) × 2 (relationship between the 3 target and distractors: semantically related, unrelated semantic and neutral) is within the experimental design, test when distracted by objects as pictures, left - right level of judgment and long - wide judgment the two appearances tasks, to test whether the response by the impact of object recognition. The results show that: the completion of the reaction when the left - the right level of judgment representation task is significantly longer than the left - right level of judgment task, the target - distracted by the relationship between the words in the relevant case long - Wide judgment the presentational task of reaction; The reaction time is longer than the other two cases. Second experiment 2 (type of DISTRACTOR: pictures, words) × 3 (relationship between the target and distractors: semantically related, unrelated semantics and neutrality) × 2 (time: first run the experiment, the second conduct experiments), to investigate whether the role can enhance the distraction is a picture and distracter words under different conditions, the interference. The second experiment results show that: the irrelevant and neutrality the significantly longer relevant under the conditions of the reaction; related words DISTRACTOR of interference effect does not exist. Experiment 3, change the experimental task, 3 (target and distractors: semantically related semantics related and neutral) × 2 (time: first run the experiment, the implementation of the second experiment) within experimental design, to explore the the senior classification task under the words in the interaction between the recognition and object recognition. The results show that: The related cases the picture DISTRACTOR not exist interfere senior classification task. Instead, relative to the neutral and the relevant circumstances, the the irrelevant distraction picture semantic categorization task interference. Experiment IV, 2 (visual similarity: visual similarity, visual similarity) × 3 (target and distracter in the relationship: semantically related semantics are not related and neutral situation) test within the experimental design to explore appearance generated from the picture DISTRACTOR interference role is mainly produced in the semantic the characterization level or the level of visual representation. Experiment four findings: target - distracted by the relationship between words in a related case, the reaction is longer than the other two cases, the interference of visual similarity between the high and low two groups are equal, that interference in the semantic representation level. rather than the visual representation level. This study show that the picture distracted by the presence of semantic interference role the words DISTRACTOR there is no category interference; related When DISTRACTOR is visual rather than semantic, there is no semantic interference; experimental tasks for advanced classification task found no semantic interference; the Head - DISTRACTOR visual similarity between no semantic interference effect; the start of DISTRACTOR, object recognition, semantic interference can not be eliminated. Thus, experimental studies have shown that, from picture DISTRACTOR interference may be produced in the semantic representation level. The goal prompted the the word extract semantic characterization information and thus can produce mental imagery in the visual buffer from DISTRACTOR semantic characterization of an impact on this process. Therefore, the generation and detection of object recognition on mental imagery, generated at the semantic level of representation rather than the level of visual representation.
