  1. 1. 1. If someone asked you what memory is (to define) memory, what would you say? 2. Are there different types / kinds of memory? If so, brainstorm some. 3. How important is the ability to remember? Why? Explain your thoughts? 4. Without our memory we would not survive. Agree or disagree, and explain your choice. 5. Without memories we would not know who we are. Agree or disagree, and explain your choice.
  2. 2. The concept of memory is difficult to define. Memory is one of those abilities that we take for granted. Certainly memory is related to learning. Memory: Is the system or process by which the products or results of learning are stored for future use.
  3. 3. Serial Learning: - Material that has been learned must be repeated in the order which it was presented. Examples: - Phone numbers - Simple procedure like how to make coffee - Math equations
  4. 4. Paired-Associate Learning: - Items to be recalled are learned in pairs. During recall, one member of the pair is presented and the other is to be recalled. Example: Learning a foreign language, basic definition study, etc. Free Recall: - When material that has been learned may be repeated in any order. Here the task is to remember as many items as possible, regardless of their order Example: Essay Answers.
  5. 5. 1. Who was Herman Ebbinghaus? 2. What are nonsense syllables and why are they important? 3. Explain the curve of forgetting. 4. What is a recognition test (provide an example). 5. What is a relearning test? What does it show?
  6. 6.  Advertisers have found a strategy that emphasizes free recall. . . Use music.  How many commercials have you seen or heard that did not include music or a jingle?  Advertisersassume that we are more likely to remember brands and products if they are associated with catchy phrases or jingles.
  7. 7.  Surprisingly little research has been conducted to verify this assumption  Results of research that has been done are mixed:  Some studies have yielded a positive correlation between memory and music, some have found no relationship, and still others have found that music can actually interfere with recall.  Most psychologist conclude that items associated with musical jingles or catchy phrases are easier to retrieve from memory, but that pairing an item with music it does not necessarily enhance recognition of those items

  10. 10.  Theencoding-storage-retrieval model of memory would serve our purpose well if we only had one type of memory to store  However, we have at least three well-defined types of memory:  Sensory Memory  Short Term Memory  Long Term Memory
  11. 11. D C R M Y N S V I E G Z
  12. 12.  Therefore the information processing model of memory must be modified: Encoding – “type” of storage – Retrieval 1. Sensory Memory: - Storage of sensory events such as sights, sounds, and tastes, with no further processing or interpretation - Provides us with a very brief image of all the stimuli that are present at a particular moment - it is quite large
  13. 13.  Lasts only briefly about one half to one second, depending on which sensory systems are involved  Sensoryinformation that is not selected for further processing by higher brain centers is displaced by incoming stimuli and may be lost completely
  14. 14.  Once info has be selected from sensory memory, it is transferred to our conscious awareness  Info must be processed in STM before it can be transferred to more permanent storage in LTM  STM lasts only for a short period of time  Itappears that items are lost from STM in 10 -20 seconds
  15. 15.  Forexample: one study found that participants’ recall of a three-letter stimulus fell from 90% correct immediately following the presentation of the stimulus, to 5% correct after 18 seconds There are two reasons for this: 1. Unless memories are practiced or rehearsed they become weaker and fade away 2. To make room for new incoming information some of the memories in STM are pushed out or displaced
  16. 16. For example: In the same experiment as above participants counted backwards by threes (an interfering task) after learning the three-letter stimulus. The result was that most Short Term information was simply lost.
  17. 17.  Theory states that we can hold approximately 7 (+-) 2 items in our STM  What about phone numbers that are 10 digits with the area code?  Grouping or chunking things is the solution  STM is limited to five to nine items 7(+-)2, each of those items may consist of a chunk or group of items
  18. 18.  Initial15-20 second STM leads to a second phase called working memory  Working memory – the intermediate processing stage between STM and LTM, where attention and conscious effort are brought to bear on the material For example: you are in class listening to a lecture in which a definition is mentioned. While you hold what the teacher is saying in your STM, you retrieve word meaning from LTM. Then you use Working memory to make sense of the new sentence you just heard.
  19. 19.  Memory stage that has a very large capacity and the capability to store information relatively permanently  Rehearsalor practice is important in the transfer of information from STM into LTM Two types of memory rehearsal: 1. Maintenance Rehearsal 2. Elaborative Rehearsal
  20. 20.  Maintenance Rehearsal: rehearsal used when we want to save or maintain a memory for a specific period of time.  Elaborative Rehearsal: Meaning is added to the material to be remembered. - This leads to more permanent memory and promotes transfer of information into LTM.
  21. 21.  Some memory loss is due to fading or decay of memories over time (Curve of Forgetting)  Other memory loss is caused by interference  There are two main types of memory interference:  Proactive Interference  Retroactive Interference
  22. 22. Proactive Interference: Situation in which previously learned (old) information hinders the recall of information learned more recently (new information) For example: You move into a new house but find yourself still using your old address and phone number Example 2: In January many people continue to write the previous year’s date
  23. 23. 2. Retroactive Interference: - Situation when information learned more recently (new information) hinders the recall of information learned previously (old information) - Models of memory suggests that when a memory is recalled from LTM and enters our consciousness, it may be combined with new information that have been received, creating a new memory. - If this new modified memory is properly rehearsed it may be transferred back to LTM for permanent storage

  26. 26. 10 Techniques for Improving Memory: Influential Factors: 1.Number of study sessions: - Generally the greater the number of sessions the better the learning and memory 2. Distribution of Study Sessions: - Sessions should be spread out. Spaced practice is more effective than massed practice 3. Meaningfulness of Material: - If you attach meaning you will learn better and remember longer
  27. 27. 4. Similarity of items: - a group of items of the same general type will be learned better than a group of dissimilar items 5. Serial Positioning: - Items at the beginning and end of a study session or list will be learned better than items in the middle of the study session or list 6. Mnemonic Devices: - When you are not able to attach authentic meaning to information, creating associations to help you remember the material will increase memory
  28. 28. 7. Imagery: - Creating mental images or pictures in your mind enhances recognition and recall of information 8. Grouping or Chunking: - grouping similar items together into categories helps to remember them better 9. Coding: - Creating special codes to help learn material that lack relevance 10. Exercise regularly – Both mind and body
  29. 29.  What was his technique?  Walk a path several times  Then hang a memory on each significant part of the path.  We are going to do that.
  30. 30.  Walk a path in the school.  Classes are in session so you need to be silent.  As you walk the path create 10 anchors.  These could be rooms or teachers.  It should be some place where you have a memory.  Walk the path 4 times! Memorize the order of your anchors.  Attach a memory technique on an anchor.  Try to have meaning to the association  Ex. Maybe Serial Positioning could be associated with the Foods’ Lab (Cereal -> food, get it?)

  38. 38.  French for “Already Seen”  There are 40 theories  70% of population stated to have experienced it  Most in ages 15 – 25  result from an overlap between the neurological systems responsible for STM and those responsible for LTM. The events would be stored into memory before the conscious part of the brain even receives the information and processes it.  Disorders  Eye seeing faster than the other eye.
  39. 39. Eye- Witness Testimony  One of the most intriguing applications of the “encoding specificity hypothesis” has been in the area of eye witness testimony  Such testimony often play an important part in jury trials  Listen to story.  What cues were present when the accident was present?  What cues were present when the statement was made?  Is it possible for the drivers of the 2 cars to modify the memories of the eye witness as they discussed the accident?  When you retrieve a memory from LTM it is placed in STM. New information can then me added to the memory.
  40. 40.  The” states that the effectiveness of memory retrieval is directly related to the similarity of the cues present when the memory was encoded.
  41. 41. Eyewitness Continued…  The possibility that eyewitness reports may be inaccurate has stimulated a large amount of psychological research  Psychologists have found that when a memory is retrieved from LTM, it appears to be placed in STM for processing  While in STM it is possible to add new information to a memory and then re-encode the modified memory  The next time you retrieve the new memory, your report may not correspond exactly to what actually happened because the new memory now contains the additional information  This effect was tested in several experiments conducted by Elizabeth Loftus
  42. 42.  American psychologist  Focus of her work was on human memory and how it can be changed by facts, ideas, suggestions and other forms of post- event information  Her interest in memory began with one of her first studies The Lost in the Mall experiment.  Discovered what she termed as “False Memory Syndrome”  Discovered the “Misinformation Effect:  a memory bias that occurs when misinformation affects people's reports of their own memory.
  43. 43. Famous Car Accident Reconstruction Experiment: Experiment: - Two groups of people watched a series of slides that showed a collision between a red sports car and another automobile - One groups saw the red sports car approach a stop sign at the intersection, the second group saw the sports car approach a yield sign at the intersection - After the slide presentation was complete the participant were asked a series of questions about what they had seen.
  44. 44.  For half of the participants in each group the questions were consistent with what they had seen  For the participants in each group, the questions were inconsistent with what really happened – if they had seen a stop sign, the question referred to a yield sign, etc.  Finally, all participants were shown both pairs of slides and asked to pick the one they had actually seen. The results were startling:
  45. 45.  75% of individuals who were asked consistent questions after seeing the slides correctly picked the slide that they had seen  Only 40% of the participants asked the inconsistent questions were able to select the slide they had actually seen.  The experiment proved that questioning had altered their memory of the incident  Loftus repeated a similar experiment, called the Crash Experiment and found similar results.  Recently Loftus had found similar findings in what became known as the “Bugs Bunny” experiment
  46. 46. In addition to demonstrating the memory –altering effects of questioning. Loftus did many other controversial experiments involving the accuracy of eye witness testimonies. Her findings all concluded three important things: 1. Participants have trouble distinguishing between individuals of other races 2. Violence interferes with memory retrieval 3. The degree of confidence of an eye witness is not related to the accuracy of the memory.
