Forgetting is a result of
either:
Encoding Failure
Storage Decay OR
Retrieval Failure
Forgetting As Encoding Failure
 Information
system
never enters the memory
Encoding Failure: Which Penny is the
Real Deal?

Forgetting As Interference
Learning some items may disrupt retrieval of
other information.
 Sometimes new memories interfere with
storing old memories – teachers often forget
names of former students as they learn the
names of their current students
 Sometimes old memories interfere with new
memories – Cable channel lineup changes

Storage Loss: Amnesia
 Amnesia
refers to the
loss of memory.
 Amnesiac patients
typically have losses in
explicit memory.
Types of Amnesia

Anterograde Amnesia: type of memory loss where
patients are UNABLE TO FORM ANY NEW
MEMORIES. Can’t remember anything that has
occurred AFTER a traumatic head injury.

Retrograde Amnesia: type of memory loss where
patients are UNABLE TO REMEMBER PAST
EVENTS. May forget everything that happened
BEFORE a traumatic head injury.
Revisiting Terms: Retrieval
Failure
 Tip
of the Tongue phenomenon: when
we are certain we know something yet we
are unable to recall it.
 Relates to retrieval failure, usually priming
or external cues will help you recall the
information you are looking for.
Motivated Forgetting
 Motivated Forgetting is the idea that
people unknowingly revise their
history. Ex: I broke up with her; she
didn’t break up with me.
 What purpose might motivated
forgetting serve?
Motivated Forgetting As A Freudian
Concept

Repression: idea put forth by
psychoanalytic theorists like
Freud which states anxiety
arousing thoughts, feelings, and
memories can be banished from
consciousness.

Ex: child abuse, rape, incest
may be repressed and not be
able to be actively recalled.
Freud believed Repression was a
Defense Mechanism

Freud argued individuals often “forgot”
traumatic incidents to protect their self concepts
and to minimize external anxiety.

Freud argued “Forgotten” incidents are
banished the “unconscious.”

The incidents may cause you to have
unexplained phobias or problems, that won’t be
helped until you uncover the incident.
Repression and Controversy of Child
Abuse

In the late 1980’s a book came out called “The
Courage to Heal” which encouraged people to
recover memories of abuse.

Following the book, “Recover Memory
Therapists” arose in great numbers and many
people began reporting incidents of “repressed”
abuse.

Sometimes “repressed memories” were used
as evidence against individuals in court cases.
Defining Memory Construction

Memory Construction refers to the idea that
memories are NOT objective recordings of the
actual events we experience.

Our memories are often affected by our preexisting schemas and involve information
filtering and interpretations.

We can have real memories of events that
never took place or that are filled with
inaccuracy because we fill in memory gaps with
plausible guesses.

 Lost in a Mall

Misinformation Effect and Memory
Construction
 Misinformation
Effect:
incorporating misleading
information into one's
memory of an event.
 Children are most
susceptible to the
misinformation effect.
Memory Construction Continued

Source Amnesia:
attributing to the wrong
source an event that we
experienced, heard about,
read about, or imagined
(misattribution)
 Ex:
Reagan’s story about
WWII gunner was actually
from a movie he saw.
 Hillary Clinton had the same
occurrence during an
election when she claimed
she rode on a helicopter
I
am going to show you a list of words.
 Your

 When
I am finished I will ask you to
