Section 1
Memory and the Brain
• Two theories regarding the physiological changes that occur when we learn something: – A change in the neuronal structure of nerves occurs.
– Learning is based on molecular or chemical changes in the brain.
Section 1
Memory and the Brain
(cont.)
• Procedural memory involves activity in an area of the brain called the striatum.
• Declarative memories result from activity in the hippocampus and the amygdala.

Section 2
Recall
•
Recall
involves a person’s knowledge, attitudes, and expectations.
• Recall is influenced by
reconstructive processes
.
• Adding addition information not in memory is called
confabulation
.
Section 2
Recall
(cont.)
• Our memories may be reconstructed in terms of
schemas
•
Eidetic memory
•
State-dependent learning
occurs when you recall information easily when you are in the same physiological or emotional state or setting you were when you originally encoded the information.
Elizabeth Loftus Section 2
Filling in “gaps” in a story would be an example of what?
A.
Schemas

Section 2
Forgetting
• When information that once entered long term memory is unable to be retrieved, it is said to be forgotten.
• Forgetting may involve: –
Decay
–
Interference
– Repression Section 2
Forgetting
(cont.)
• Two kinds of blockage: – Proactive – Retroactive Section 2
Forgetting
(cont.)
• Amnesia—a loss of memory that may occur after a blow to the head, brain damage, drug use, or severe psychological stress.
• Infant amnesia—the relative lack of early declarative memories.
Section 2
Forgetting
(cont.)
• Theories for why we do not remember being young: – Freud thought that memories are repressed because of the emotional traumas of infancy.
– Others believe that because infants do not yet understand language, their memories are nonverbal, whereas later memories are verbal.
Section 2
Forgetting
(cont.)
– Others claim that the hippocampus may not be mature enough in infancy to spark memories.
– Or that infants have not yet developed a sense of self to experience memories.

Section 2
Improving Memory
• Techniques for improving memory are based on efficient organization of the things you learn and on chunking information into easily handled packages.
•
Elaborative rehearsal
Section 2
Improving Memory
(cont.)
• Ways to protect a memory from interference: – Overlearn it.
– Avoid studying similar material together.
– Use distributed practice, or study a little at a time.
Section 2
Improving Memory

•
Mnemonic devices
• Examples: – The Method of Loci – “Thirty days has September” – “Every Good Boy Does Fine” – Mental pictures Section 2

Stages of Memory
Psychologists often compare human memory to a computer; however, unlike a computer, people can never fill their long-term memories so full that there is no room left for storage.
Figure 1
Spot the Real Penny
Which is the genuine penny among the fakes? Even though you live in the United States and probably see hundreds of pennies a week, it is difficult to identify the real one. Mere reception, such as seeing something over and over again, does not guarantee a strong memory.
Figure 2
Using Short-Term Memory
Glance quickly at the left figure in this pair, then look away. How many dots did you see? Now do the same with the right figure. You were probably surer and more accurate in your answer for the right figure.
Figure 3
Three Systems of Memory
The moment you pay attention to information in sensory memory, that information enters short-term memory. Then that information remains in short-term memory for a few seconds. If you rehearse that information, it stays; if you do not, it disappears.
Figure 4
Memory Centers in the Brain
Researchers have identified the parts of the brain that are involved in memory.

The Processes of Memory
Memory involves three processes.

Elizabeth Loftus 1944 –
“One of the things that we know about memory for very upsetting experiences, traumatic experiences, is that the memory does not work like a videotape recorder.” Profile

storage:
the process by which information is maintained over a period of time Vocab3
retrieval:

the process of grouping items to make them easier to remember Vocab8
semantic memory:
knowledge of language, including its rules, words, and meanings Vocab9
episodic memory:
chronological retention of the events of one’s life Vocab10
declarative memory:
stored knowledge of learned skills that does not require conscious recollection Vocab11

memory retrieval in which a person identifies an object, idea, or situation as one he or she has or has not experienced before Vocab13
recall:
memory retrieval in which a person reconstructs previously learned material Vocab14

the alteration of a recalled memory that may be simplified, enriched, or distorted, depending on an individual’s experiences, attitudes, or inferences Vocab15
confabulation:
memory gaps the act of filling in Vocab16
schemas:
conceptual frameworks a person uses to make sense of the world Vocab17
eidetic memory:
the ability to remember with great accuracy visual information on the basis of short-term exposure Vocab18
