Oscillatory interference in parietal cortex: a mechanism to represent order in working memory
The Validity of dⲠMeasures
Subliminal perception occurs when prime stimuli that participants claim not to be aware of nevertheless influence subsequent processing of a target. This claim, however, critically depends on correct methods to assess prime awareness. Typically, dⲠ(âd primeâ) tasks administered after a priming task are used to establish that people are unable to discriminate between different primes. Here, we show that such dⲠtasks are influenced by the nature of the target, by attentional factors, and by the delay between stimulus presentation and response. Our results suggest that the standard dⲠtask is not a straightforward measure of prime visibility. We discuss the implications of our findings for subliminal perception research
