How can we improve our memory? What are the types of memory? Why do we forget?
3
What are the three memory processes?
4
A.What does it do?
5
Encodes (input) - processes information into memory Mental representation a.Automatic b. Effortful
6
- places information into memory
7
Takes information out of storage a. Recall Reconstructing a memory ex- b. Recognition - identifying that something is familiar ex.
8
Write an example of recall and recognition
9
Journal reflections are due on Friday- don’t forget Journal reflections will not be accepted late! ◦ Printer issues? Email it to me by 2:30
10
What are the three stages of memory?
11
1. Sensory register 2. Short term 3. Long term
12
1. Shallow Simple repetition Not an effective way to encode information
13
Forming associations between new information that is already stored Information has meaning and is easier to remember
14
You used elaborative processing You used shallow processing

16
Using the information just taught, explain why it is difficult to remember what a penny looks like
17
A. Sensory register 1. Information is held for a split second
18
A. Prevent the mind from being overwhelmed B. Provides stability, playback and recognition C. Give decision time Which allows you to decide if something is important
20
A. Selective attention Concentrating on one sensation without completely blocking out other sensations
21
basic need, novel something of interest
22
- focusing on the significant characteristics of information

ONE VERTICAL LINE ONE HORIZONTAL LINE TWO RIGHT ANGLES TWO VERTICAL LINES ONE HORIZONTAL LINE FOUR RIGHT ANGLES HOW IS THIS FEATURE EXTRACTION
24
a. Iconic - visual memory information is held for a quarter second. b. Echoic - auditory memory information is held for 1-2 seconds
26
1. Information is held for about twenty seconds
27
What is your immediate memory span?
28
Most people can remember 7-9 items
29
Number tested Period 2Period 3Period 4 5 6 7 8 9 10
30
7 unrelated items Plus or minus Capacity can be increased by chunking - putting information into meaningful chunks
31
1. What is the first stage of memory 2. Explain Iconic memory 3. What is feature extraction? 4. What is the capacity of short term memory? 5. What is chunking?

33
What is serial position effect?
34
- MOST PERMANENT MEMORY STORAGE WITH UNLIMITED CAPACITY AND DURATION
36
Night Bed quilt dark silence fatigue clock snoring toss turn tired artichoke rest dream Sleep
37
- retention depends on the order in which information is presented PRIMACY EFFECT - ENHANCED ABILITY TO REMEMBER FROM THE BEGINNING OF A TASK
38
RECENCY EFFECT - ENHANCED ABILITY TO REMEMBER ITEMS FROM THE END OF A TASK
39
SEMANTIC DISTINCTIVENESS - SOMETHING DIFFERENT THAN THE NORM B. Spacing - information is remembered if there is time to process in between tasks
40
You are called in for an interview and can choose your time 9,10,11,12 or 1 What time do you pick? Why What would you do if you had the 11 time?
41
Read page 246
42
A. EXPLICIT (DECLARATIVE) -MEMORIES YOU ARE CONSCIOUSLY AWARE OF B. IMPLICIT- (PROCEDURAL) - MEMORIES YOU ARE NOT CONSCIOUSLY AWARE OF
43
Semantic- GENERAL FACTUAL KNOWLEDGE. WORDS, LANGUAGE RULES, DATES
44
MEMORIES FROM PERSONALLY EXPERIENCED EVENTS - (episodes of your life)
45
MEMORIES RELATED TO SKILLS AND HABITS WE ARE UNAWARE OF THESE HABITS AND CANNOT RETREIVE THEM
46
1. Swimming is what type of memory Proceduralsemanticepisodic 2. How long is info held in STM? 3. How long is info held in sensory register 4. Remembering items at the beginning of the list is known as the 5. The artichoke was an example of…?
47
A man without short term memory A man without short term memory What type of memory does he still have? How do you know?
48
write down 2 examples of each type of long term memory ◦ One example per notecard (do not identify the type but make sure you know what it is)
50
A. RECALL VS RECOGNITION 1. RECOGNITION - RETRIEVING INFORMATION FROM MEMORY WHICH INVOLVES DETERMINING WHETHER SOMETHING IS FAMILIAR Give me an example
51
2. RECALL - RETRIEVING INFORMATION FROM MEMORY WHICH REQUIRES RECONSTRUCTING THE MEMORY Give me an example
52
- remembering parts of the information and then filling in the rest with what makes sense to you ( making up memories)
53
simplifying the material
54
highlighting or overemphasizing material
55
changing details to better fit subjects own background or knowledge
56
The professor…
57
Using the cartoon on the bottom left, identify the type of memory used in first two clips What term other than the type of memory fits this cartoon?
58
1. Identifying if something is familiar 2. Simplifying information when remembering ( taking out details) 3. Changing details to fit your background 4. Highlighting parts of a memory 5. Remembering the homecoming game (memory type)
59
1. CONTEXT - YOU RECALL MORE ACCURATELY IN THE SAME SITUATION THE EVENT TOOK PLACE - SIMILAR CONTEXTS TRIGGER DEJA VU
60
2. STATE-DEPENDENT MEMORY - IMPROVED RETRIEVAL WHEN IN THE SAME MENTAL, EMOTIONAL, OR DRUG INDUCED STATE THAT WAS PRESENT WHEN THE MATERIAL WAS LEARNED
61
Think about our final exam procedures. Based purely on what you learned about memory, If you were an administrator, where would students take exams and why? If you are diagnosed with ADD in June and are given medicine to help your ADD what would a memory expert say about you starting medicine right before your finals?
62
On the top of the page, Explain the difference between proactive and retroactive interference
63
1. Decay Forgetting is caused by passage of time
64
We forget information because related information causes confusion (This happens with memory, completing tasks and learning new things)
65
Interference occurs with previous learning decreases ability to remember recent material Ex. A teacher can’t remember your name, they call you your siblings name
66
Recently learned material interferes with ability to remember or learn old material Ex. Your teacher can’t remember your older sibling’s name, they can only remember yours *
67
Time your neighbor as they say the following words…
68
Red Orange Yellow Green Blue Purple
69
Red Orange Yellow Green Blue Purple
71
Anything that is too painful for you to remember is stored in the unconscious mind
73
Take out both memory packets and Answer these now… 1. Previous learning interferes with memory is called? 2. Who is Clive Wearing? 3. remembering something at the beginning of a list is called… 4. What is episodic memory? 5. What are the 3 stages of memory?
74
What are mnemonic devices? What are mnemonic devices How can we use them?
75
1. Subjective organization A personal way to remember things
76
2. Acronyms
77
Visualize associations between already memorized places and new things to be memorized
78
- associating number word rhymes and items to be memorized
81
Make it useful!
