Using ERPs to Investigate Two-Dimensional and Three-Dimensional Image Recognition

Debates and arguments about the differences and similarities between two-dimensional and three-dimensional image recognition have long existed. This study aims at using event-related potentials (ERPs) to investigate the mechanisms of human brains and the differences and similarities of brain functions when the operation of two-dimensional and three-dimensional image recognition is triggered. The experiment for this study was practiced by performing ERP tasks designed separately by using two-dimensional and three-dimensional images. Simultaneously, off-line analyses of collected brain-wave data of the experimental subjects were performed. The subjects in the experiment were 20 volunteer senior high school and vocational school students. The results of this study suggest significant differences between the amplitude from N1 and P300 in the central midline sites and from P1 in the occipitotemporal cortex while two-dimensional and three-dimensional images were displayed to the subjects. Therefore, the researchers
