NAME: HOUR: THE STAGES OF MEMORY (pg. 238-254) The Stage Model of Memory: Maintenance Rehearsal Sens ory Memory Attent ion Working or term Memor Three Stages of Memory Differ in How their… y Input 1. Enco ding Retri eval - –How info can be stored 2. - –How the info can be stored 3. - What is done with the o Information is -term memory info capacity and duration. from stage to another. Sensory Memory: o Function—holds information long enough to be processed for basic characteristics o Capacity— o can hold items at once o Duration—very retention of images o sec for visual info o 2 sec for auditory info o Sensory memory forms , without attention or interpretation o is needed to transfer information to working memory o Neisser's Selective Attention Test - At any particular moment, we focus our attention on just a of our experience Divided into two types: 1. memory–visual information 2. memory– auditory information o Auditory sensory memories may last a bit than visual sensory memories o What did Sperling Study show about our short-term ability to visually encode information? -1- Working or Short-Term Memory (STM): o Function processing of information o Where information is worked on o Capacity - limited (holds items) o Duration - brief storage (about seconds) o Code - often based on even with visual inputs Maintenance Rehearsal – Allows information to remain in working memory longer than the usual seconds o Mental or verbal of information o What happens if you don’t use maintenance rehearsal? Peterson’s STM Task - Test of memory for 3-letter o Participants count backwards for a few o Without rehearsal, memory syllables , then recall Working Memory Model: Visuospatial Sketch pad Central Executive Phonological Loop o Visuospatial sketch pad - holds and info o Phonological loop - holds information o Central executive all activities of working memory; brings information into working memory from sensory and long-term memory Ways to improve STM: Chunking - Grouping bits of information into larger units of information– expands working memory load. Give an example of this: Long Term Memory (LTM): o Once information passes from sensory to working memory, it can be long-term memory o Function— and information o more form of storage than working memory o capacity o Duration—thought by some to be o Encoding—process that controls movement from memory storage (getting info in) -2- into memory to o Retrieval—process that controls flow of information from memory store (getting info out) to Encoding: Automatic and Effortful Processing: o Some information, such as where you ate dinner yesterday, you process o Other information, such as this chapter's concepts, requires and remember. Automatic Processing – to encode encoding of information. Examples? Effortful Processing - Requires and conscious o Maintenance Rehearsal – go over something till it is encoded in LTM o Elaborative Rehearsal – relate the info to info you . o Self-reference effect – applies info to . o Visual – vivid images you can remember. o Levels of Processing framework – info encoded at a level will be more easily remember than info encoded at a level. How can you do this? (See middle of page 246). Craik and Lockhart's levels of processing framework - Information that is processed at a “ ” level is more likely to be encoded into long-term memory than information processed at a “ ” level o When studying for classes, actively new information, think about its implications, and try to generate your own based on your experiences Types of Long Term Memory Dimensions of LTM: o Explicit memory—memory with recollected; also called ; information can be consciously memory -3- Implicit memory—memory awareness; memory that affects behavior but cannot consciously be recalled; also called memory 2 Types of Explicit Memory: 1. Episodic information—information about 2. Semantic information—information about Q: Why are these explicit memories? A: Because you can… or “episodes” , school work 3 Subtypes of Implicit Memories: 1. Classical Conditioning - Implicit because it is retrieved 2. Procedural Memories - Memory that enables you to perform specific learned or responses o They are automatically when appropriate 3. Priming - influence of one on another o It is implicit because it does not depend on and is automatic 2 Types of Priming: 1. Conceptual Priming - The meaning of priming stimulus influences your encoding or retrieval o Does not depend on sense modality (works across the senses) 2. Perceptual Priming - Prime enhances ability to identify a test stimulus based on its features o Does work across sense modalities o Clustering: Hierarchical Organization: o Related items clustered together to form o categories clustered to form higher-order categories o Remember list items better if list presented in o poorer recall if presented Even if list items are random, people still organize info in some pattern Semantic Network Model: o Mental links between o common provide basis for mental link o Shorter path between two concepts = association in memory o Activating one concept can and activate other associations. -4-
