Sensory memory

  1. 1. B. Sensory Memory: Recording <br />
  2. 2. What is SENSORY ?<br />
  3. 3. What are 2 Forms of Sensory memory? <br />Ionic memory<br />Echoic memory <br />
  4. 4. 2 Forms of Sensory <br />Ionic memory – holds visual information for about a one third of a second or more.<br />Example: blinking of the eye. <br />
  5. 5.  Echoic memory – holds auditory information for 1 or 2 seconds. <br />
  6. 6. Example:<br />A less scientific demonstration of echoic memory is the "What did you say?" phenomenon, which goes like this:<br />Person #1: "What time is it?"<br />Person #2: "What did you say? Oh, 2:30."<br />The second person hears the question after asking, "What did you say?" This is due to echoic memory, which holds the sound of the question for a second or two. Even if you were not paying attention to the words when they were uttered, you can "hear" them when you turn your attention to them. “<br />
  7. 7. Example:<br />
  8. 8. 1 Prevents being overwhelmed.<br />It keeps you from being overwhelmed by too many incoming stimuli (information). <br />Why sensory memory avoid stimulus to overload? <br />Preventing incoming information to vanished.<br />Function of Sensory Memory<br />
  9. 9. 2 Gives decision time.<br />It gives you to decide whether information is important. Information you pay attention will automatically transferred to short term memory.<br />
  10. 10. 3 Provides stability, playback and recognition.<br /> Iconic memory plays back visual information. Echoic memory plays back auditory information.<br /> <br />
  11. 11. INFO:<br />Sensory memory allows us to take a 'snapshot' of our environment, and to store this information for a short period. Only information that is transferred to another level of memory will be preserved for more than 1 à two seconds.<br />
  12. 12. C. Short term Memory: Working<br />Short-term memory- holds a limited amount of information –an average of seven items-for a limited period of time - 2 to 30 seconds..<br />
  13. 13. Chunking- is combining separate items of information into a larger unit, or chunk.<br />Example: When recalling a number such as 14101946, group the numbers as 14, 10, and 1946, to create a mnemonic for this number as a date, month, and year.<br />
  14. 14. Interference results – when new information enters short term memory and pushes out information that’s already there.<br />Example: You are trying to remember a phone number and someone ask you a question, the question interfere s with or wipes away the phone number.x<br />
  15. 15. Function of Short Term Memory<br />1 Attending- to paying attention to information that is relevant and disregards everything else.<br />
  16. 16. 2 Rehearsing- holds information for a short period of time until you decide what to do.<br />
  17. 17. 3 Storing- to store or encode information in long-term..<br />
