We tested whether the magno-cellular projection is sufficient to support awareness independent face processing. On the basis of the magno-cellular projection’s exclusive sensitivity for LSF bands, we expected that peripheral, masked HSF primes would not be processed, but that masked unfiltered primes, masked LSF primes, and unmasked HSF primes would lead to a congruence effect. In five experiments, all of these predictions were confirmed. We found that masked unfiltered primes led to a congruence effect and that masked HSF primes did not (Experiment 1). We showed that masked unfiltered primes and masked LSF primes both led to significant congruence effects of about similar size (Experiment 2). We demonstrated that unmasked HSF primes created a congruence effect, while masked HSF primes failed to create a congruence effect (Experiment 3). Control Experiments concerning balancing the prime faces for spatial frequency contents (Experiment 4), and further for the contrast (Experiment 5) confirmed the above findings. Our findings are in agreement with an origin of unaware vision in processing along the magno-cellular pathway.
