ENCODING – Encountering material/information that needs to be put into a form in which it can be put into our memory2. STORAGE – Keeping the information in your memory until it is needed3. RETRIEVAL – Being able to come up with the information stored in your memoryModal Model of Memory:Sensory memoryShort term (working) memoryLong term memoryThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.SENSORY MEMORY1. What is sensory memory? A brief persistence of sensory information2. Types of sensory registers (memory):- Iconic Memory – Where visual information is processed - Echoic Memory – Where auditory information is processed3. Questions:- How does sensory memory work?- How much information can be registered in sensory memory?- How much information can be processed in sensory memory before it dissipates?- How fast does information dissipate?Sperling Studies of Sensory Memory1. Flash matrix of letters/numbers for 1/20 sec.2. Subjects reported what they saw3. Counted pieces of information rememberedResults:1. People could report 4-9 pieces of information2. But they could see all of the informationIssue:Being able to do something with the information before it dissipates.SENSORY MEMORYQuestions/Answers:- How does sensory memory work? Hold sensory info. In it raw form so that it can be coded into some understandable means and transferred to STM- How much information can be registered in sensory memory? Infinite amounts- How much information can be processed in sensory memory before it dissipates? Up to 9 pieces of information at a time- How fast does information dissipate? Very fast, less than three secondsSHORT TERM MEMORYDoes it exist?Primacy effect: We typically remember the first few words on the listRecency effect: We typically remember the last few words on the listSHORT TERM MEMORY QUESTIONS:Does it exist? Primacy vs. Recency effects in memoryPrimacy - Long term memoryRecency - Short term memoryHow big is it - how much information can it hold? We can hold seven + or – two pieces of information in short term memoryChunking 7 plus or minus chunks of
