The document discusses different aspects of memory, including short term memory and long term memory. It describes how long term memory has a large capacity and duration for storing information through dual coding of images and words. The document also discusses eidetic or photographic memory, which is the rare ability to remember images with extreme accuracy and recall details with high precision. This type of memory is illustrated through the example of Solomon, a newspaper reporter, who was able to recite back large volumes of information perfectly. However, Solomon lacked understanding of abstract meanings. The document also touches on cognitivism in education and its view that learners think in different cognitive models, and instructors should use varied techniques to engage different cognitive capacities.
