Subthreshold semantic priming: Not a context effect

Bernstein, Bissonnette, Vyas, and Barclay (1989) showed that masked primes can be recognized more often when followed by a related target than when followed by an unrelated target. They suggested that this effect may allow subjects in subthreshold semantic priming experiments to recognize the masked primes on the related semantic priming trials, even when the subjects cannot recognize masked primes presented alone. The present experiment found that when masked primes are presented at recognition rates comparable to those used in published studies of subthreshold masked priming, the forced choice recognition of masked primes followed by related targets was similar to that of masked primes presented alone (25% vs. 22%). In addition, the recognition of masked primes on the forced choice trials was highly predictive of masked prime recognition on the semantic priming trials.
