【 摘 要 】

To estimate conscious perception with objective measures, participants are typically asked to discriminate between stimuli. Perceptual consciousness is thus operationalized as the ability to discriminate between visual stimuli (Eriksen, 1960). Because biased responding can influence overall accuracy, a bias free signal detection measure, d' or sensitivity, is usually calculated. If d' is not significantly different from zero, it follows that there was no conscious perception of stimuli. This is considered by many the most rigorous procedure, yet it has been criticized on several grounds (Reingold and Merikle, 1988, 1990).
