Memory refers t the processes that allow us to record and later retrieve experiences and information. Atkinson and shiffrin model memory has 3 major components: sensory memory, short term or working memory, and long-term memory. Short-term/working memory: holds the info we are conscious of at any given time consciously processes, codes, and works on information. Mental representations once info leaves sensory memory, it must be represented by some type of code if it is to be retained in short-term and eventually long-term memory. We may try to form a mental image (visual encoding), code something by sound (phonologic encoding), or focus on the meaning of a stimulus (semantic encoding). For physical actions we code patterns of movement (motor encoding) Maintenance rehearsal: the simple repetition of information elaborative rehearsal: involves focusing on the meaning of information or relating it to other things we already know more effective in transferring info into long-term memory.
