Sensitivity Assumption Merikle and Reingold proposed the relative sensitivity assumption in response to Holender's assumptions, which they claimed to be the only assumption required for studies on unconscious cognition. The relative sensitivity assumption assumes that the "sensitivity of a direct discrimination is greater than or equal to the sensitivity of a comparable indirect discrimination to conscious task relevant information." In other words, Reingold and Merikle argued that it is impossible for indirect measures to provide a more comprehensive understanding of relevant perceptual information than for direct measures such as indirect discriminations are always less than or equally sensitive to relevant perceptual information to direct discriminations. Meta-Analyses Merikle has also coauthored two significant meta-analyses titled Consciousness and Cognition. as well as Working memory and language comprehension: A meta-analysis which supported the findings that predictive power of working memory measures such as reading span and listening span is greater than storage capacity measures such as word span and sentence span in showing comprehension.
