The stimuli and results of Experiment 4. a) Illustration of stimulus sequence of Experiment 4 (related pairs). Context word (ORANGE) is presented to the one eye for 100 msec and the first random texture frame is presented to the other eye after 400 msec of fixation. Three random texture frames are presented in sequence, one every 100 msec. The target word (APPLE) is presented dichoptically for 100 msec with the second random texture frame. b) Behavioral results of Experiment 4 (N=16). Accuracy of the semantic-judgment task (blue), lexcial-decision task (red) and feature-discrimination task (greeen) are plotted across the three visibility levels. Error bars indicate ±1 S.E. The chance level (50%) is plotted with the black solid line and the accuracy associated with lexicial-decision task performance without interocular suppression is plotted with the black dotted line. ERP waveforms and the N400 amplitude obtained from c) high d) intermediate and e) low-visibility levels. Details are identical to Figure 1b and 1c. The black curve in e) represents ERP waveform elicited by the monocular random texture pattern without target words.
