Memory: HM is a patient who underwent surgery to remove his hippocampus, amygdala, etc. (the temporal structures in his brain that induced his seizures). HM could keep new information available for 20-30 seconds, but then lost it. His ability to learn new facts was gone, but he was able to remember his past. Memory is divided into sensory memory (millisecond – 1 second), short term memory (less than one minute) and long term memory (days, months, years) Sensory memory exists for each of our senses. Iconic is for visual memory, and echoic is for auditory memory. The sensory memory is unprocessed, and is for less than a second. The purpose is to keep information about a stimulus after the stimulus has disappeared. Iconic Memory: Assessed visual sensory memory, presented subjects a 3 x 4 matrix of letters Two recall conditions: - Whole Report (report as much as you can remember) - Partial Report (shows the sensory store is larger than what was previously shown with the whole report method) Short Term Memory Purpose: holding of information in active state Duration: 15-30 seconds, may be increased with rehearsal Trace decay theory: automatic fading of the memory trace due to the passage of time Remember ‘BRG’: 3 seconds later: 80% recall correctly, and 18 seconds later 7% recall correctly Interference theory: disruption of the memory trace by other traces (where the degree of interference depends upon the similarity of the two memory traces Capacity: 7 +- 2 elements (digit span task) Chunking: reorganization of information into meaningful units (3-5-2-9-3-4-9-1= 35-29-34-91) Short Term Memory Code - Index to information stored in long-term memory (verbal code only)? Or does it contain sensory information (e.g. visual code)? - Mental Rotation Task (Shepard and Metzler): Are the objects the same? RT depends on the amount of rotation Working Memory - A system for actively holding and manipulating transitory information in mind - Baddley and Hitch model of working memory Phonological Loop: stores and rehearses speech based information Episodic Buffer: link visual/verbal to LTM Visual Spatial Sketchpad: manipulates visual images Central Executive: Decision / attention Long Term Memory - Purpose: store associations - Capacity: unlimited - Duration: days, months, years - Codes: semantic (meaning); episodic (autobiographical events); procedural (procedures) Serial Position Effects - Evidence for the distinction between LTM and STM - Pr
