Working/Short-Term Memory Vast amounts of info are registered by our sensory memory, but only some are brought forward without attentional flashlight. We also retrieve info from long-term storage for “on-screen” display. But unless we rehearse/encode with our working memory, it will quickly disappear from our short-term memory.

Working capacity: short-term memory typically stores seven or so bits of info (give or take 2)called Magical Number Seven, plus or minus two by George Miller Rapid decay with no rehearsal Long-Term Memory Capacity: essentially limitless an average adult has about a billion bits of info in memory and a storage capacity that can accommodate about a thousand to a million times that amount. Duration: forgetting occurs as new experiences interfere with our retrieval and as the physical memory trace decays. Synaptic Changes Synapse: sites where nerve cells communicate with each other through their neurotransmitter messengers....
