Chapter 5 Memory - the process involved in retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original info. is no longer present. Clive Wearing - parts of temporal lobe destroyed that are important for forming new memories. Lives within most recent 2 minutes of his life. Atkinson and Shiffrin’s modal model of memory 3 Major Structural Features of the Modal Model: 1. Sensory memory - initial stage that holds all incoming info for seconds or fractions of a second. 2. Short-term memory - holds 5-7 items for about 15-30 seconds. 3. Long-term memory - can hold a large amount of info for years. Memory system includes control processes - processes that can be controlled by the person and may differ from one task to another. Example: rehearsal Sensory memory - the retention, for brief periods of time, of the effects of sensory stimulation. Persistence of vision - retention of perception of light in your mind (sparkler). Sterling’s Experiment- flashed array of letters, asked to report as many letters as possible. Two methods to determine capacity: whole report and partial report. Ionic memory (visual icon)- brief sensory memory for visual stimuli. *Less than 1 second. Echoic memory - brief sensory memory for auditory stimuli. *2-4 seconds. Short Term Memory - holds small amounts of info for brief periods. Proactive Interference - interference that occurs when info that was previously learned interferes with learning new info. *Interference is the basic mechanism of forgetting in STM, not decay. Digit span - between 5 and 8 digits. Chunking - small units (like words) can be combined into larger meaningful units (phrases, sentences, paragraphs). Can now hold 5-8 “chunks” instead of 5- 8 items. Auditory Coding - Ex) the sound of a person’s voice. Proof: misidentified letters (written) more likely to be ones that sounded similar. Visual Coding - Ex) Image of a person. Proof: Chinese symbol experiment, radicals (not associated with sound) vs. characters. Still able to remember some radicals even though no sound or meaning. Semantic Coding - Ex) Meaning of what person is saying. Placing words into categories involves the meanings of words. Modern approach replaces STM with working memory - a limited-capacity system for temporary storage and manipulation of info for complex tasks such as comprehension, learning, and reasoning. Differs from STM in 2 ways : 1) STM is single component, while working memory consists of multiple parts. 2) STM is concerned mainly with holding info, whereas working memory is concerned with the

manipulation of info that occurs during complex cognition. Working memory accomplishes the manipulation of info through the action of 3 components : 1) Phonological loop - holds verbal and auditory info 2) Visuospatial sketch pad - holds visual and spatial info. 3)
