Memory can be defined as the mental system for receiving, encoding, storing, organizing, modifying and retrieving information (Coon and Mitterer , 2012). Often, we are able to remember something, such as how to drive a car, but we are unable to remember a mathematical formula for a test. Some people's memory abilities vary among individuals, and research has proven that even infants differ in their memory abilities (Fagan & Singer, 1963). Psychologists have discovered that memory is not static, but rather is influenced by internal factors and situational events to a large extent (Huffman, Vernoy & Vernoy, 1997). This essay will attempt to discover which study method is most appropriate, by listing and explaining various memory strategies, as well as indicating how each method will improve memory efficiency. The memory process is composed of three operations. The first being Encoding, it involves the conversion of information into a form that allows it to be stored in memory (Coon & Mitterer, 2012). The second operation is called Storage, it is the retention of information until it is needed later. The third and final operation is known as Retrieval, and it is the retrieval of information from Storage (Hoeksema, Fredrickson, Loftus & Wagenaar, 2009). These previously mentioned operations each represent a step in the memory process (Sternberg & Sternberg, 2012). There are different levels of information processing, these are called levels of processing theory (Goldstein, 2008). This theory was proposed by Fergus M Craik, a senior research scientist at the Rotman Research Institute at Baycrest and Robert S. Lockhart, a professor in the Department of Psychology at the University of To...... middle of article... ... ence. (3rd edition.).
