论文摘要

解离范式检查了主要处理的间接度量与主要意识的直接度量之间的解离。有争议的是直接措施是客观的还是主观的,以及是否应在相同或单独的试验上获得这些措施。在两个Metacontrast实验中,我们分别或在多个任务中测量了主要的歧视,PAS等级和响应启动。单个任务显示启动中最快的响应,因此很可能符合快速练习理论中假设的前馈处理的假设。同样,双重任务允许素数快速激活。然而,延长的响应和较慢的错误更频繁地发生。相比之下,三重任务对响应激活有负面影响:响应大大减慢,快速锁定的错误丢失了。此外,降低启动效应和主要识别性能会导致双重解离。在这里,违反了无意识响应启动,进食处理的必要条件。

Dissociation paradigms examine dissociations between indirect measures of prime processing and direct measures of prime awareness. It is debated whether direct measures should be objective or subjective, and whether these measures should be obtained on the same or separate trials. In two metacontrast experiments, we measured prime discrimination, PAS ratings, and response priming either separately or in multiple tasks. Single tasks show the fastest responses in priming and therefore most likely meet the assumption of feedforward processing as assumed under Rapid-Chase Theory. Similarly, dual tasks allow for a fast response activation by the prime; nevertheless, prolonged responses and slower errors occur more often. In contrast, triple tasks have a negative effect on response activation: responses are massively slowed and fast prime-locked errors are lost. Moreover, decreasing priming effects and prime identification performance result in a loss of a double dissociation. Here, a necessary condition for unconscious response priming, feedforward processing, is violated.
