Final answer:
Endel Tulving supported the Multiple-Memory System because he believed that memory is composed of multiple systems or types of memory.
Step-by-step explanation:
Endel Tulving supported the Multiple-Memory System because he believed that memory is not a single, unitary process, but rather is composed of multiple systems or types of memory. Tulving proposed the distinction between episodic memory, which is the memory of personal experiences and events, and semantic memory, which is the memory of factual knowledge and concepts.
Tulving's support for the Multiple-Memory System was based on his research on memory encoding and retrieval processes. He conducted experiments that showed different levels of processing, such as visual, acoustic, and semantic processing, can impact memory performance. This supported the idea that different types of memory rely on different cognitive processes.
