Implicit Category Priming Capacity, Edward Paulus Hahn

Walden Dissertations and Doctoral Studies

Past research has shown that accessing a memory allows faster subsequent access to the memory activated as well as to related information (priming). There has been much research devoted to implicit category priming (unintentional priming of a category of information), but this research has not determined the number of categories that can be implicitly primed simultaneously. The goal of the present quantitative study was to address that gap. Twenty participants (ages 27-54 years, M=44 years), who volunteered through an online participant pool, were presented with 2 tasks over the Internet. A scrambled phrase task implicitly primed 5 unrelated categories and …
