Abstract: Neural mechanisms of object recognition, especially the neural mechanisms of novel artificial objects expertise recognition are an important window to investigate the brain plasticity. In current research, the event-related potential was used to investigate the formation process of non-face object inversion effect. Two kinds of participants were selected: (1) Experts of a certain kinds of object recognition without any arbitrary trained by experimenter, such ability formed in daily life; (2) novice participant who recognize novel artificial objects with or without arbitrary training. Through manipulating the magnitude of inversion effect in a serial experiment, we aim to dissociate specific ERP components of expertise recognition and explore the brain plasticity of object recognition. The whole project tries to propose our own model which can explain the relationship between the level of experience from a certain orientation of object and the selection of processing strategies in object recognition. The result of this project also could provide the exact evidence of cognitive neuroscience to support and improve theory of configural processing continuum.
