A TRUE STORY
In my mind I’ve returned to that scene many times, and each time the memory gains
weight and substance. I can see the cool pine trees, smell their fresh tarry breath,
feel the lake’s algae-green water on my skin, taste Uncle Joe’s iced tea with freshsqueezed lemon. But the death itself was always vague and unfocused. I never saw
my mother’s body, and I could not imagine her dead. The last memory I have of my
mother was her tiptoed visit the evening before her death, the quick hug, the
whispered, “I love you.”
It was some thirty years later that Elizabeth began to remember the details surrounding her mother’s
death. While at her Uncle Joe’s ninetieth birthday party, Elizabeth learned from a relative that she
had been the one to discover her mother’s body in Uncle Joe’s swimming pool. With the realization,
memories that had eluded Elizabeth for decades began to come back.
The memories began to drift back, slow and unpredictable, like the crisp piney smoke
from the evening campfires. I could see myself, a thin, dark-haired girl, looking into
the flickering blue-and-white pool. My mother dressed in her nightgown, is floating
face down. “Mom? Mom?” I ask the question several times, my voice rising in
terror. I start screaming. I remember the police cars, their lights flashing, and the
stretcher with the clean, white blanket tucked in around the edges of the body. The
memory had been there all along, but I just couldn’t reach it.
As the memory crystallized, it suddenly made sense to Elizabeth why she had always felt haunted by
her vague memories of the circumstances surrounding her mother’s death. And it also seemed to
partly explain why she had always been so fascinated by the topic of memory.
However, several days later, Elizabeth learned that the relative had been wrong—it was not Elizabeth
who discovered her mother’s body, but her Aunt Pearl. Other relative confirmed that Aunt Pearl had
been the one who found Elizabeth’s mother in the swimming pool. Yet Elizabeth’s memory had
seemed so real.
The Elizabeth in this true story is none other the Elizabeth Loftus, a psychologist who is nationally
recognized as the leading expert on the distortions that can occur in the memories of eyewitnesses.
Even though Loftus is an expert on memory distortions and false memories, she wasn’t immune to the
phenomenon herself. Loftus experienced firsthand just how convincing a false memory can be. In
retrospect, Loftus can see how she actively created information in her own mind that corresponded to
the inaccurate information that she had been the one to discover her mother’s body. As Loftus
writes, “That elaborate but completely fabricated memory confronted me with its detail and precision,
its utter lack of ambiguity.” (Loftus & Ketcham, 1994).
The Phenomenon of Memory
Objective1: Define memory, and explain how flashbulb memories differ from other
memories.

Memory:

Types of Memory
o Episodic Memory:

Flashbulb Memory:
o Semantic/Generic Memory:
o Procedural Memory:
Many activities require all three types of memory.
For example: Playing the game of tennis
Semantic Memory: Knowing the official rules of how many sets are needed to win a match
Episodic Memory: Remembering who served last or remembering the score
Procedural Memory: Knowing how to lob or volley
Now you come up with your own example…
Information Processing
Objective 2: Describe Atkinson-Shiffrin’s classic three-stage processing model of
memory, and explain how the contemporary model of working memory differs.

Storage:

Retrieval:
Analogy
A library, for example, must have some ways of acquiring and cataloging information
(encoding), retaining it (storage), and making it available to the users (retrieval).
Another good analogy is a computer. Now you come up with your own example…

Recognizing Factors in Memory Encoding
Check your understanding of various factors at work in memory encoding by identifying
each of the vignettes below as an example of one of the following:
(A) semantic encoding
(B) elaboration
(C) visual imagery
(D) attention
_____1. As Zach reads the next chapter in his psychology textbook for the first time, he
stops whenever he comes across a word he doesn’t understand and looks it up in a
dictionary. In addition, at the end of each paragraph he stops and quizzes himself to
determine whether he understands what he’s just read.
_____2. On the bus riding home from work, Zeon relaxes by reading books about baseball.
He’s really interested in learning the intricacies of baseball strategy. It’s a more
challenging subject than he thought, so he really has to concentrate on shutting out
the noise and other distractions that go along with riding a bus during rush hour.
_____3. Zelda has discovered that many of the foreign-sounding vocabulary terms in her
anatomy and physiology course are similar to common English words. Futhermore,
she has realized that if she forms mental pictures of the objects these English words
remind her of, she is often better able to remember the meaning of the vocabulary
terms.
_____4. While Dr. Riley is lecturing on theories of motivation, Zoe is thinking of examples
in her own life of each of the concepts Dr. Riley is introducing.

Three sins of forgetting:
o Absent-mindedness:
o Transience:
o Blocking:
Three sins of distortion:
o Misattribution:
o Suggestibility:
o Bias:
One sin of intrusion:
o Persistence:
Encoding Failure
Objective 19: Discuss the role of encoding failure in forgetting.
On explanation for forgetting is that we fail to encode information for entry into our memory
system. Without effortful processing, much of what we sense we never notice or process.
In the space below draw the front side of a penny.
How accurate were you? Why is this a difficult task even though you have
probably looked at thousands of pennies in your life?
Storage Decay
Objective 20: Discuss the concept of storage decay, and describe Ebbinghaus’
forgetting curve.

According to Ebbinghaus
Retrieval Failure
Retrieval failure can occur if we have too few cues to summon information from long-term
memory.
Interference
Objective 21: Contrast proactive and retroactive interference, and explain how they
can cause retrieval failure.

Proactive interference:

Retroactive interference:
Motivated Forgetting
Objective 22: Summarize Freud’s concept of repression, and state whether this view is
reflected in current memory research.

Repression:
Memory Construction
Memories are not stored as exact copies, and they certainly are not retrieved as such. Rather,
we construct our memories, using both stored and new information. In many experiments
around the world, people have witnessed an event, received or not received misleading
information about it, and then taken a memory test. Results show that people often
misremember.
Misinformation and Imagination Effects
Objective 23: Explain how misinformation and imagination can distort our memory of
an event.

Misinformation effect:
Source Amnesia
Objective 24: Describe source amnesia’s contribution to false memories.

Source Amnesia (source misattribution):
Discerning True and False Memories
Objective 25: List some differences and similarities between true and false memories.
Unreal memories feel like real memories. Neither the sincerity nor the longevity of a
memory signifies that it is real. The most confident and consistent eyewitnesses are often not
the most accurate.
Memories of imagined experiences are usually limited to the gist of the supposed event—the
meanings and feeling we associate with it. True memories contain more details than
imagined ones.
Children’s Eyewitness Recall
Objective 26: Give arguments supporting and rejecting the position that very young
children’s reports of abuse are reliable.
A supporting argument is that even very young children can accurately recall events if a
neutral person talks to them in words they can understand, asks nonleading questions, and
uses the cognitive interview technique. A challenging argument is that preschoolers are more
suggestible than older children or adults, and they can be induced, through suggestive
questioning, to report false events.
Repressed or Constructed Memories of Abuse?
Objective 27: Discuss the controversy over reports of repressed and recovered
memories of childhood sexual abuse.
Improving Memory
Objective 28: Explain how an understanding of memory can contribute to effective
study techniques.

Overlearn:

Use elaborative rehearsal:

Rehearse actively:

Use mnemonic devices:

Capitalize on context effects and mood congruence:

Study the material as close to when you learn it as possible:

Be able to not only recognize the information but to also recall it:

Remember the primacy and recency effect:

When memory can be helped or hindered by similarities in the environment.
4.
Also known as short-term memory, it can hold seven plus or minus two items for
approximately 18 to 20 seconds.

when the encode it they attribute the wrong source to the event and convince themselves that
they actually remember the event happening when actually they only heard about it.
13.
Catchwords, jingles or phrases to help you recall particular facts (ex: ROY G. BIV or In
1492 Columbus sailed the ocean blue).

questions for example)
19.
The gradual disappearance of the mental representation of a stimulus.
20.
Learning of new information interferes with recall of older information.
21.
A measure of memory in which the learner need only identify the stored material (multiple
choice questions for example)
22.
The process through which people deliberately try to remember something.
23.
Old information interferes with learning or remembering new information.
24.
The first step in the memory process when information is coded and put into memory.
