Unformatted text preview: Chapter 7 Memory I. Memory as Information Processing- The mind as a processing system that encodes stores, and retrieves information. Encoding Refers to getting information into the system by translating it into a neural code that your brain processes Storage Involves retaining information over time. Retrieval Refers to processes that access stored information. A. A three Stage Model Sensory Memory- Briefly holds incoming sensory information- Visual registers : hold information about 3 to 5 letters- Auditory registers : hold information about the precise details of a sound for several seconds Working Memory- A memory store that temporarily holds a limited amount of information- Memory codes are mental representations of some type of information or stimulus, which take several forms. For example: visual codes, phonological codes, semantics codes, and motor codes.- Capacity : 72, limited- Duration : limited, about 20 seconds- Temporary holding station along the route from sensory to long term memory. - A mental workspace that stores information, actively manipulates it, and supports other cognitive functions such as problem solving. - Components : 1. Phonological loop : stores mental representations of sounds 2. Visuospatial sketchpad : stores visual and spatial information, as occurs when we form a mental image of someone. 3. Episodic buffe r: A temporary storage space where information from long-term memory and from the phonological and visuospatial subsystems can be integrated, manipulated, and made available for conscious awareness. Comes into play after chunking . 4. Central executive: directs the overall action. Plans and controls the sequence of actions that need to be performed. Long term Memory- It is our vast library of more durable stored memories with unlimited capacity and duration . - Distinctiveness of Short-term memory? Serial position effect : the ability to recall an item is influenced by the items position in a series....
