Cerebellum. The hippocampus is the part of the brain involved in the encoding of information. The different interactive exercises are presented as fun brain games that can be played on a mobile device or computer. But before a memory is cemented into long-term memory as episodic memory, it must pass through the semantic memory, noted Endel Tulving of the University of Toronto in his book, Elements of Episodic Memory . 1993, Kitchener et al.

After much research on amnesic patients, researchers believe that both of these types of memory are located in different areas of the brain and largely act independently. Qualitatively, the associations and categories formed by people with schizophrenia on tasks of semantic categorisation e.g. We may have great variation in the capacity of these different memory systems. For example, if we sustained damage to visual semantics, our knowledge of living creatures would become impaired. It helps us talk, communicate, and learn about the objects and concepts of the world around us. What is semantic memory? Episodic memory and semantic memory together makeup part of your long-term memory and are known as declarative memory. Poor semantic verbal fluency also independently predicted progression to amnestic MCI (OR, 1.86; 95% CI, 1.12-3.52). brain damage at an early age, developed an extremely poor episodic memory, while preserving reasonably good semantic memory (Vargha-Khadem, Gadian, Watkins, Connelly, Van Paesschen & Mishkin, 1997). So now you can see more about how semantic memory works by understanding some examples of this type of memory. For example, when studying for a test, you’ll learn the information much better if you give it some kind of meaning aside from the concept itself. by problems in naming objects and pictures, in defining objects, and by poor comprehension of oral and written language.  |  Using working memory, you can manipulate the information in your short-term memory in different ways.
