Abstract In order to figure out the effect of perceptual load and expectation on inattentional blindness and the interaction, we modified the sustained and dynamic paradigm. The experiment （N = 48 participants） was 2（high and low expectation） × 3 （high, moderate, and low perceptual load）mixed design. The result showed that the number of ignored object reported in high expectation condition was significantly larger than that in low expectation condition. Levels of perceptual load did not result in significant difference in detection. The number of ignored object reported under different levels of expectation was significantly different under moderate and low perceptual load conditions, while under high perceptual load condition, the effect wasn’t detected. The result suggested that expectation did affect the detection of ignored object and its effect differentiated among levels of perceptual load.
