Feature-based attention to unconscious shapes and colors

摘要: Two experiments employed feature-based attention to modulate the impact of completely masked primes on subsequent pointing responses. Participants processed a color cue select pair possible targets out multiple basis their color, and then pointed one those two with prespecified shape. All target pairs were preceded by prime triggering either correct or opposite response. The time interval between was varied course attentional selection. In second experiment, roles shape switched. Pointing trajectories showed large priming effects that amplified attention, indicating modulated earliest phases motor output. Priming as well modulation occurred even though participants remained unable identify primes, distinct processes underlying visual awareness, response control.
