This document summarizes key points from Chapter 5 of a cognitive development course. It discusses cognitivism and the modal model of memory, which includes sensory, short-term and long-term memory. Sensory memory is fleeting and limited, while short-term memory lasts less than 20 seconds. Long-term memory has an unlimited capacity and is the result of encoding through processes like rehearsal, elaboration and organization. The document also outlines potential issues with long-term memory like fading, distortion and interference, and recommends instructional strategies to address them like repetition, emphasis on salient features, and teaching for transfer.
