Objectives: Chapter 8 (Memory) (pages 327-367) Summarize Atkinson-Shiffrin’s classic three-stage processing model of memory and describe two important concepts contemporary memory researchers have added to improve upon this model. Memory is the persistenece of learning over time. The Atkinson-Shiffrin classic three-stage memory model (encoding, storage and retrieval) suggests that we register fleeting sensory memories, some of which are processed into on-screen short-term memories, a tiny fraction of which are encoded for long- term memory and, possibly, later retrieval. Contemporary memory researchers note that we also register some information automatically, bypassing the first two stages. And they prefer the term working memory (rather than short-term memory) to emphasize the active processing in the second stage. Identify two types of sensory memory. As information enters the memory system through our senses, we briefly register and store visual images via iconic memory, in which picture images last no more than a few tenths of a second. We register and store sounds via echoic memory , where echoes of auditory stimuli may linger as long as 3 or 4 seconds. Describe three functions of working memory and report its average capacity. Working memory is a newer understanding of short-term memory that focuses on conscious, active processing of incoming auditory and visual-spatial information, and of information retrieved from long-term memory.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
