This posting traces the memory system from stimuli into long-term memory. It also discusses the features of each step and factors that enhance or impede information flow in each step of the process.
Although the memory topic is vast, I offer some ideas to get you started:
First, as you trace stimuli to long term memory and features of each step and factors that enhance or impede information flow in each step of the process, please note the vital role of sensory memories. Research suggests how they "act as buffers for stimuli received through the senses. A sensory memory exists for each sensory channel: iconic memory for visual stimuli, echoic memory for aural stimuli and haptic memory for touch. Information is passed from sensory memory into short-term memory by attention, thereby filtering the stimuli to only those which are of interest at a given time" (http://www.cc.gatech.edu/classes/cs6751_97_winter/Topics/human-cap/memory.html).
You might also add how information transmits from sensory memory into short-term memory. Attention is like a ...
