Memory: Understanding the Complexities of Memory Systems
1.
2. 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.
3. 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.
4. 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
5. 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.
6. 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?
7. 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.
8. 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

12. 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
14. 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
15. 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
16. 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
17. 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
18. 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.
19. 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
20. 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.
21. 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
22. 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.
23. 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
24. 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
25. 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

28. 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
29. 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
30. 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
31. 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.
32. 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?)
33. Question #5 Will be discussed / presented and Handed
in by group:

3. Focuser – Redirects the group back to the task at hand when
they get off task
4. Time Keeper – reminds group of time remaining so that task
gets complete
5. Reporter – Shares key points of the groups discussion with
the whole class
34. 3 Major types of LTM:
1. Procedural
Memory for making responses and performing
skilled actions.
35. 2. Semantic
Memory for general knowledge.

40. 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.
41. 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.
42. The” states that the effectiveness of memory retrieval is
directly related to the similarity of the cues present when
the memory was encoded.
43.
44. 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
45. 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.
46. 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.
47.
48. 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:
49. 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
50. 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.
