Functional Disorders
of Memory
+
Functional Disorders (Hysteria)
Functional
disorders are not disorders of structure
but of function.
Such
disorders are classified as hysteria by the
DSM (Diagnostic & Statistical Manual).
They
were the only disorders retaining a
psychological explanation & etiology, rather than
being defined by symptoms.
+
Sources of Symptoms
(Psychodynamic View)
Strangulated
affect is converted into physical
symptoms by the repressed memory – called
conversion symptoms.
Symptoms
disappear if the repressed
emotion associated with an event is released
– called abreaction.
Therapy
is needed to overcome resistance to
remembering and thereby relive the trauma.
+
History of Hysteria
In
the mid-1800’s hysteria was considered
either:
Irritation
of the female sexual organs (floating
womb)
Imaginary, play-acting by women
Charcot
rejected both explanations, calling
it a neurosis also shown by men.
Charcot
thought it required hereditary brain
degeneration.
Charcot shows colleagues a female hysteria patient at
Salpetriere Hospital (Paris). Freud studied with Charcot in 1885.
+
History (Cont.)
Symptoms
included:
Paralysis
Convulsions, contractures (muscles won’t relax),
seizures – arc de cercle (arching back in rigid
posture)
Somnambulism (sleepwalking)
Hallucinations
loss of speech, sensation or memory
Charcot
recognized parallels between
hysteria and hypnosis and found he could
remove symptoms using hypnosis.
+
Janet’s View of Hysteria
Symptoms
arose from subconscious beliefs
isolated and forgotten, thus disassociated
from consciousness.
Memory
pools are normally disconnected
but become connected through mental
effort.
Traumatic
shock disrupts the mental effort
needed to associate memory pools.
+
Janet (Cont.)
Memory
pools may be associated with
fixed ideas that motivate repeated actions.
These
are seen in fugue states or
sleepwalking or the emotions
seen in multiple personality
disorder’s alternative selves.
+
Freud’s View of Hysteria
Freud
studied with Charcot and later wrote
“Studies in Hysteria” with Breuer, based on
the case study of Anna O.
He
thought “hysterics suffer mainly from
reminiscences”:
Traumatic
memories are pathogenic (disease-
creating)
Banishment of memories requires repression
Affect is damned up or strangled.
+
Freud’s Seduction Theory
Repressed
memories nearly always
revealed seduction or sexual molestation
by an adult.
The
patient doesn’t know what is repressed
so the therapist must overcome resistance
to uncover it.
Later, Freud
decided that fantasies,
impulses and wishes caused repression.
+
Classifications of Hysteria
Dissociative
disorders
Posttraumatic
Somatoform
Sleep
stress disorder (PTSD)
disorders
disorders
+
Dissociative Disorders
Disruption
of the usually integrated
functions of memory, consciousness,
identity or perception of the environment.
These
include:
Dissociative
amnesia
Dissociative fugue
Dissociative identity disorder (DID, also MPD)
Depersonalization disorder
+
Dissociative Amnesia
Impairment
is reversible and usually
reported retrospectively (in past tense).
Types
of disturbance:
Localized
– affects a few hours around a
traumatic event.
Selective – affects some but not all events during
a period of time, or some categories.
Generalized – affects entire past.
Continuous – a specific time up to the present
+
Dissociative Fugue
Sudden, unexpected
travel away from one’s
home or workplace with inability to recall
the past.
The
person may assume a new identity or
be confused about his or her identity.
Wandering
may be motivated by a fixed
idea (repetition compulsion).
Return
to pre-fugue state brings amnesia

+
Dissociative Identity Disorder
(DID)
Also
called multiple personality disorder (MPD).
Presence
of two or more distinct identities or
personality states with memory loss across states.
Failure
to integrate identity, memory and
personality.
Primary
personality is passive, guilty, dependent,
depressed. Alternates may be hostile, aggressive,
controlling.
+
DID (Cont.)
Frequent
gaps in memory.
Amnesia
may be asymmetrical:
Passive identities have more constricted memories.
Active or protector identities have more complete
memories.
Transitions
May
triggered by stress.
result from sexual abuse, results in a pattern of
disruptive behavior in childhood continuing into
adulthood.
+
Depersonalization Disorder
A
feeling of detachment or estrangement from
one’s self.
A
person may feel like an observer of their own
mental processes or body.
Includes
sensory anesthesia, lack of affect, a
feeling of lack of control of one’s actions.
Voluntarily
induced in religious and trance
experiences.
+
An Identity View of Dissociation
One
function of consciousness is to
construct a mind-space that includes:
Space
and time
Abstractions of meaning (gist) and making sense
of what happens
A self, an imagined or idealized self, selfmonitoring
Narratization (autobiography, hierarchical
organization of life events).
+
Cultural Examples of Dissociation
All
cultures have some kind of spirit
possession:
Amok
syndrome
Historical examples of demonic possession
Current religious and spiritual possession
Amnesia
is often associated with such
possessions.
+
Social Construction of Dissociative
States
Spanos
considers possession to be a social
construct:
Society
provides special status and historical
factors affect its manifestation.
The possessed role is learned.
There are benefits to performing the possessed
role and it is frequently acted by the powerless.
DID
may be a socially constructed role.
+
Physiological Theories of
Dissociation
Only
a tiny percentage of individuals
exposed to stressors or trauma show
dissociative symptoms.
True
cases of DID can be distinguished from
socially constructed cases through childhood
behavior.
True
cases of DID, fugue or other amnesias
usually show histories of early childhood
brain injury or recent damage.
+
Repetition-Compulsion
PTSD
is caused by close-calls rather than
injury.
Repetition
memory.
occurs in the form of intrusive
Normally
anxiety protects us from fright but
with an unexpected shock there is no chance
for anxiety.
Repetition
creates retrospective anxiety
which builds defenses after the event.
+
PTSD (Cont.)
Avoidance
of reminders of the event can include
amnesia for some aspect of the event.
Reexperiencing includes dreams and intrusive
recollections.
Dreams
and recollections are not factual but
recreations of idealized or feared features of an
event.
Content changes during therapy.
+
Somatoform Disorders
Unintentional
symptoms of a medical
disorder without a medical cause:
Somatization
disorder – multiple symptoms
(formerly just called hysteria)
Conversion disorder – voluntary motor or
sensory dysfunction with psychological cause.
Hypochondriasis – fear of illness.
Pain disorder – pain whose onset, severity and
maintenance have a psychological cause.
+
Conversion Disorder
Pseudoneurological
– related to voluntary
motor or sensory function.
Symptoms
include impaired coordination or
balance, paralysis, weakness, difficulty
swallowing or lump in throat, double vision,
blindness or deafness, seizures.
The
more medically naïve the person, the
more implausible the symptoms.
+
Conversion Disorder (Cont.)
The
symptom represents a symbolic resolution of
an unconscious conflict.
Primary
gain is keeping the conflict out of
awareness.
Secondary
gain is external benefits and relief from
responsibilities.
Neurological
conditions such as MS can be
misdiagnosed as conversion disorder.
+
Sleep Disorders
Dyssomnias
– sleep problems.
Parasomnias
– abnormal behavior associated with
sleep.
Nightmares
and sleep terrors – nightmares are not
memories, sleep terrors usually cannot be
remembered.
Hypnagogic
hallucinations – occur at sleep onset,
vivid, accompanied by wakefulness.
+
Sleepwalking Disorder
(Somnambulism)
Repeated
episodes of complex motor behavior
initiated during sleep, with limited recall upon
waking.
Difficulty
being awakened, with confusion upon
awakening.
As
with fugue, the person may attempt to carry out
a fixed idea.
Lady
Macbeth is an example.
+
Myth of Hypnosis
Spanos
is a critic of traditional views of
hypnosis.
He
argues against the idea of hypnosis as
an altered state of consciousness in which
people:
Have
unusual experiences.
Have abilities not available to them normally.
Cannot lie and will do things without question.
+
Sociocognitive View of Hypnosis
Hypnotic
behaviors can be explained using
normal psychological processes.
The
term hypnosis refers to a historically rooted
conception of hypnotic responding held by the
participants.
Responding
is context-dependent:
Determined by the willingness of subjects to adopt the role
Modified by their understanding of that role.
+
Components of Hypnotic Situations
An
induction procedure
Now, includes suggestions that the subject is becoming
relaxed or sleepy.
Administration
of suggestions calling for specific
behavioral or subjective responses.
Arm levitation (raising)
Hypnotic
responding is stable over time.
+
What is Hypnotic Responding?
Traditional
view says that a trance state is induced
in which people respond involuntarily to
suggestions.
Sociocognitive
view says that responding reflects
expectations and attitudes people bring to the
session.
Hypnotic subjects retain control over their actions, even
when experienced as involuntary.
+
Fallacies
Hypnotic
responding is no better than nonhypnotic responding to suggestions.
Neither
produces long term change in smoking,
wart removal, etc.
There
is no unique quality to hypnotic
trance that cannot be simulated.
People
are not necessarily faking, but anything a
hypnotized person can do, a non-hypnotized
person can too.
+
Explaining Dramatic Behaviors
Negative
hallucinations – deafness,
blindness.
Delayed
auditory feedback – “deaf” hypnotized
subjects behaved like non-hypnotized.
Demand
characteristics – depends on how
the question is asked.

+
Involuntariness
One
of the chief demands of the hypnotic situation
is the loss of will.
Sociocognitive view says subjects retain control and use it
in goal-directed ways.
Subjects interpret their responses as involuntary in order
to conform to social demand – woman swatting fly.
Wording
of suggestions affects involuntariness.
+
Studies of Spirit Possession
Spanos
argues that other “dissociative”
experiences are the result of cultural suggestion,
enacting a social role.
Not
all cultures have multiple personality disorder
(DID or MPD), but some enact multiple
personalities as spirit possession.
Human occupant of a body is temporarily displaced by
another self that takes over.
+
Speaking in Tongues
Glossolalia
(speaking in tongues) occurs in the
context of a religious ceremony.
May be accompanies by convulsions, eye closing or
unconsciousness, etc.
Interpreted
as the holy spirit taking over and
speaking in His own language.
Interpretation may follow, with amnesia.
Learned
and practiced behavior.
+
Spirit Mediums
The
medium becomes possessed by a spirit or
series of spirits who help the client.
The
ceremony involves behaviors marking the
transitions, and observer responses the validate
the performance.
+
Example of Spirit Possession

h/difficulties/Ghosts_Demons/violent_manifestation.php
+
Learning the Possessed Role
In
some families, being a medium runs in the
family and the spirit moves from one relative to
another.
In
some cases, people apprentice to learn the role.
Kardec introduced spirit mediums into Puerto Rico where
“espiritistas” replaced folk healers.
The first possession may arise during distress.
+
Peripheral Possession
A
person with little social status or power becomes
possessed by a member of another person’s
family.
That possessing spirit begins making demands that must
be met by the other family.
Women
may adopt peripheral possession roles in
order to engage in behavior otherwise not
tolerated – e.g., Malaysian factory workers.

dream (Fiddler on the Roof) – a way of
letting a spirit ask his wife for what he cannot:

+
Historical Demon Possession
Symptoms
of demon possession from the
New Testament:
Convulsions, sensory and motor deficits, enactment of
alternate identities, loss of voluntary control,
increased strength, amnesia
These symptoms ultimately coalesced into a relatively
stereotypic social role.
Largely
a conversion tool, so possession
increased with competition among religions.
+
Witchcraft and Demon Possession
In
the 15-17 centuries, demon possession was
associated with witchcraft (part of a Satanic
conspiracy).
Compendium
Maleficarum – witchhunting manual
from the 17th century.
People
who were of low social status but
intelligent, well-traveled, or privy to thoughts and
actions of others were suspected.
Behaviors
of those possessed were involuntary

+
Socialization of Demoniacs
Clerics
taught those possessed their role.
Initially symptoms were ambiguous.
Later, became convulsions, being bitten, and seeing
spectres of witches attacking them.
Catholic
& Protestant treatment of demons varied.
Enactments sometimes used strategically.
+
Evidence of Social Construction
Incidence
of demon possession has varied widely
across cultures and across time periods with
inconsistent symptoms.
Some experts diagnose many more cases than others.
The
more attention paid to the symptoms, the more
elaborate they become.
