Mental imagery occurred when perceptual information was accessed from memory, giving rise to the experience of "seeing with the mind eyes" and so on.lt influenced the human learning, thinking activities, memory and verbal ability.It is an important part of the structure of human intelligence. Similarly, object recognition is an important ability of human people in daily life. Every day we are receiving a lot of information from the environment and in most cases we can understand the information of object recognition and identification.The visual information of the Three-dimensional objects from the outside world was projected onto the retina and then the two-dimensional image viewer was fonnede.It matched to the information in the memory.So the object recognition based on two-dimensional image is taken place.Most researches test of the visual representation and the interaction between visual perception and visual image. The promotion and interference between visual perception and visual image provided a large number of basis of the relationship of them. However, there is lack of the in-depth study of the influence of visual Object Recognition on the generation and inspection of visual Imagery.Our experimental research were aimed to explore whether and how visual object recognition influence the Visual Imagery,such as the processing of generation and inspection.Experiment 1 is a within-subject design of 2 (Type of task:making left-right higher spatial judgments and making taller-wider judgments)×3(Target-distractor relations:related,unrelated and neutral condition).Results from Experiment 1 showed that responses in the tasks of making left-right higher spatial judgments were longer when the simultaneous picture distractor was categorically related to the target distractor relative to unrelated and neutral target-distractor combinations and the responses of left-right higher spatial judgments was longer than making taller-wider judgments.Experiment 2 is a within-subject design of 2 (Distractor type:picture and word)×3(Target-distractor relations:related,unrelated and neutral condition)×2(Time:Timel and Time 2).Results from Experiment 2 showed that responses in the tasks of making left-right higher spatial judgments were longer when the simultaneous picture distractor was categorically related to the target distractor relative to unrelated and neutral target-distractor combinations. Task repetition and the priming of the distractor did not eliminate categorical interference. Categorical interference did not arise in the left-right higher imagery task when word distractors rather than picture distractors were presented. Experiment 3 changed the target task from one requiring generation and inspection of an image to one requiring access to a semantic representation from a word cue, namely, superordinate categorization. Participants were required to give the superordinate category name of the exemplar named by the word cue and is a within-subject design of 3(Target-distractor relations: related,unrelated and neutral condition)×2(Time:Timel and Time 2).Results from Experiment 3 showed that there was no no interference from related picture distractors on superordinate categorization of the word cue. Rather, an unrelated picture distractor interfered with semantic categorization relative to the neutral and related conditions.Experiment 4 is a within-subject design of 3(Target-distractor relations:related,unrelated and neutral condition)×2(Visual Similarity:High and Low).Results from Experiment 4 showed that responses in the tasks of making left-right higher spatial judgments were longer when the simultaneous picture distractor was categorically related to the target distractor relative to unrelated and neutral target-distractor combinations. Visual Similarity had no influence on the responses of the task.The present study suggested that categorical interference effects from picture distractors on the processes of imagery may arise at a semantic level, in the process of generating information from a semantic representation in order to subsequently place a visual image in the visual buffer. The data presented here have provided evidence for an interaction between visual object recognition and visual imagery.
