Implicit Memory and Priming
Another area where Tulving has had a significant impact is the distinction between conscious or explicit memory (such as episodic memory) and more automatic forms of implicit memory (such as priming). Along with one of his students, Professor Daniel Schacter, Tulving provided several key experimental findings regarding implicit memory.
The distinction between implicit and explicit memory was a topic of considerable debate in the 1980s and 1990s. Tulving and colleagues proposed that these different memory phenomena reflected different brain systems. Others argued that these different memory phenomena reflected different psychological processes, rather than different memory systems. These processes would be instantiated in the brain, of course, but they might reflect different aspects of performance from the same memory system, triggered by different task conditions. More recently, theorists have come to adopt components of each of these perspectives.
