Module 26: Storage: Retaining Information 2 types of sensory memory: 1. iconic memory: a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second. 2. echoic memory: a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds. 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. Duration: when asked to remember CHJ , people recalled the letters only half the time

Unformatted text preview: after 3 seconds, and rarely recalled them at all after 12 seconds. 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....

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
