There are several different types of white blood cells:
granulocytes: fight bacteria by surrounding them and "eating" them.
monocytes: fight germs, but aren't as specific as granulocytes.
B-lymphocytes: these cells attach antibodies on germs (or anything they don't think belongs) with antibodies, which in turn signal other WBCs to get the tagged germ.
T-lymphocytes: these cells signal orders to other WBCs to come to a germ, and they make those other WBCS stay at the battle sight.
RBCs, platelets, and WBCs are all made in the bone marrow. In fact, they all derive from one cell type, called a stem cell, which then differentiates into one of the three types.
 ALL, CLL, AML, and CML stand for which type of white blood cell is growing out of control. Thus:
lymphocytic: uncontrolled growth of B- or T-lymphocytes
myelogenous (granulocytic): uncontrolled growth of granulocytes
If these leukemias progress quickly, they are further denoted acute (as in ALL and AML). If they progress slowly, they are called chronic (as in CLL and CML). Acute leukemias are most prevalent in children and are therefore often called "childhood leukemias". In summary,
 ALL: acute lymphocytic leukemia
 CLL: chronic lymphocytic leukemia
 AML: acute myelogenic leukemia
 CML: chronic myelogenic leukemia

=======================================================================================================================
A pediatrician is examining a young infant and notes that the infant symmetrically abducts and extends his extremities after a loud noise and then begins to cry. This reflex is known as which of the following
Moro reflex
Chronology - emerges around 8-9 weeks in utero and is inhibited at about 16 weeks of neonate life. It is transformed into the adult startle or Strauss reflex, and should not be present in children beyond the age of one year at the very, very latest
 The Moro reflex is initiated by loud noise or sudden motion.
 It involves abduction of the extremities and extension of the elbows and knees, followed by flexion.
 The Moro reflex appears at birth and disappears at approximately 4 months of age.
If the reflex is asymmetric, this suggests extremity fracture or peripheral nerve injury.
 Also known as the startle reflex[; startle reflex; embrace reflex]
, this is the characteristic reflex of newborns.
 When the baby is startled (classically one allows the baby's head to fall back a bit), he throws his arms wide, spreading the fingers, then grabs instinctively with the arms and fingers (for his mother, of course).
 The reflex should be brisk and above all symmetrical.
 One of the functions of swaddling, in my mind, is to suppress this reflex, which often upsets the little tyke.
 An asymmetric startle reflex, in which one arm does not act symmetrically with its companion, implies a paralysis or weakness on one side of the body, most commonly Erb's palsy.
Role & description
- the Moro is a clasp reflex.
It is a panic alarm reflex which helps the baby to hang on and cry in alarm.
At birth the cortex is not wired up - we are a brain stem functioning, reflexive, floppy mass.
Built into the brain stem is the Moro reflex to protect the new born child.
As the baby cannot use the cortex to interpret the threat, the result is a panic response.
Once the adult startle reflex has been developed, the individual will use the senses (eyes and ears) to locate the source of any perceived threat and will make an intellectual, cortical decision -
should I be frightened or not? If the source cannot be located, a child may become worried and cry, but should not scream.
The startle reflex is a rapid intake of breath, blink, shoulders up and then locate the source
. Agorophobia panic victims, for example, still retain the Moro reflex.
Activation - can be activated by at least three things:
a sudden noise (auditory Moro),
movement/alteration of head position (vestibular Moro)
or change of light (visual Moro).
Reaction - the arms go out, and as the response becomes stronger, the arms come back in again.
It is the clasping or bringing back of the arms which is the Moro reflex.
So there is a rapid intake of breath, out arms, legs to a lesser degree, freeze for a second, then back come arms and legs and then the baby screams the place down!
Consequences -
If a person grows up with this reflex but manages to control it, it can affect the entire personality.
They may need to ask question after question and are not happy about change unless they have instigated it.
If they are going somewhere they want to know who will be there, what will happen and what they will have to do.
They may be uptight and egocentric, not because they want to be, but because they need to be in control as much as possible.
They also find it difficult to make relationships as they need to control the other person.
Quite often the Moro driven child, in addition to being immature, very sensitive, over reactive, and who often loses cortical control, has pupils which tend to remain enlarged under minimum stress.
Obviously, if you are very anxious or very frightened, your pupils will be more dilated than normal because of the fight/flight mechanism, but you will still have some pupillary reaction to strong light.
However, with many of the children with a strong Moro, the pupils remain dilated and they are hypersensitive to light.
They do not know when to stop and do not learn from experience.
The Moro affects the personality tremendously, and so has a very catastrophic effect it it remains present.
Adrenaline and cortisol are two of the body's main defences against infections and allergies.
If they are in use very frequently, as in the Moro driven individual, they are distracted from their primary role and the body may lack enough of them to provide immunity and a balanced reaction to potential allergens. This may be the child who catches every cold or other infection, and who over reacts to some types of medication.
The child might also be sensitive to certain foods or food additives, and this can affect behaviour and concentration.
They will also tend to burn up blood sugar quicker than other children, which will make swings in mood and performance more pronounced.
The Moro child, being oversensitive in one or more sensory channels, is often operating at a high level of awareness.
Imagine, then, the effect on such a child of simply being in a classroom - bright fluorescent lights, much movement and activity, often a great deal of noise and high temperatures - such a child can easily experience sensory overload. Add to this the fact that many of these children are stimulus bound (unable to ignore irrelevant stimuli within their visual field) and have a poor concentration span.
LONG TERM EFFECTS OF A RETAINED MORO REFLEX
1. Vestibular problems such as travel sickness or impaired coordination and balance, particularly seen during ball games.
2. Physical timidity.
3. Oculomotor and visual-perceptual problems - stimulus bound (inability to ignore irrelevant stimuli within the visual field, so that the eyes are drawn to the outline of a shape at the expense of being unable to perceive internal aspects of the shape or object).
4. Poor pupillary reaction to light, photosensitivity, dificulty with black print on white paper. The individual tires easily under fluorescent lights.
5. Possible auditory confusion resulting from hypersensitivity to certain specific sounds. The individual may have poor auditory discrimination skills and have difficulty shutting out background noise.
6. Allergies and lowered immunity - asthma, eczema or a history of frequent ear, nose and throat infections.
7. Adverse reaction to drugs.
8. Poor stamina.
9. Dislike of change or surprise - poor adaptability.
10. Poorly developed CO2 reflex.
11. Reactive hypoglycaemia.
POSSIBLE SECONDARY PSYCHOLOGICAL SYMPTOMS
1. Free floating anxiety - "Angst" (continuous anxiety, seemingly unrelated to reality).
2. Excessive reaction to stimuli:
a. Mood swings - labile emotions.
b. Tense muscle tone - body armouring.
c. Difficulty accepting criticism, as this individual finds it so difficult to change.
3. Cycle of hyperactivity followed by excessive fatigue.
4. Difficulty making decisions.
5. Weak ego, low self esteem:
a. insecurity/dependency.
b. Need to control or manipulate events

 The asymmetric tonic neck reflex (ATNR) appears at approximately 2 weeks of age and disappears at approximately 6 months of age.
 There is flexion of the arm and leg on the occipital side and extension on the chin side, creating a "fencer position.''
 The parachute reflex appears at about 8 to 9 months of age and persists voluntarily. The child is placed in the examiner's hands and is permitted to free-fall in ventral suspension. The child extends his extremities symmetrically to distribute his weight for landing.
 The grasping reflex appears at birth and disappears at about 3 months of age. This is when the infant reflexively grasps at an object placed in his palm.
 The protective equilibrium reflex appears at 4 to 6 months of age and persists voluntarily. The child is pushed laterally by the examiner and flexes his trunk toward the force to regain equilibrium while he extends one arm to protect against falling.
reflexes that persist into adulthood are:
 blinking (corneal) reflex (blinks before eyes are touched or when sudden bright light appears)
 sneeze reflex (sneezes when nasal passages irritated)
 gag reflex (gags when throat or back of mouth stimulated)
 yawn reflex (yawns when needs additional oxygen)
cough reflex (coughs when airway stimulated)
Infantile reflexes (normal in infants, abnormal in all others):
 Moro response
 tonic neck reflex
 grasp reflex
 rooting reflex
 sucking reflex (sucks when area around mouth stimulated)
 startle reflex (pulling arms and legs inward after loud noise)
 step reflex (stepping motions when sole of foot touches hard surface)
 crawl reflex (crawling motions when placed on abdomen)
 parachute reflex  parachute reflex
The Palmar Reflex
Chronology - emerges at around 11 weeks in utero and is inhibited or suppressed at about 2-4 months after birth.
Role & description -
 another of the group of 'clasp' reflexes,
 the Palmar allows the baby to practice grasping and the letting go of objects.
Activation -
 activated by stimulation in the palm of the hand.
Reaction -
 if you place your finger into the palm of the baby's hand, the thumb will come over and lock your finger, then the baby's other fingers will lock in the thumb and your finger very tightly. If you do this in both hands at the same time, the baby cannot let go. It is therefore possible to hang a baby from a washing line, but please do not try to do this!!! (there is a similar reflex present in the feet, called the Plantar reflex).
Consequences -
 the Palmar reflex should not be present beyond the first year of life, but if it remains present in children of school age, writing problems will develop.
 As soon as a pen or pencil is put into the child's hand, the fingers automatically tighten, and get tighter and tighter.
 The pressure increases on the paper and they start to lose control of the hand. It is no use telling them not to grip it so tightly! Writer's cramp is a likely result, and difficulty will be experienced in catching a ball.
 They may also not find it easy to juxtapose the fingers and thumb for rapid alternate movement, and if they cannot do this (dysdiadochokinesia), it shows that there is an immaturity of the cerebellum, and poor speech/language is a likely consequence.
 The cerebellum does not cross over, and so if you cannot do the movement on the right side, it shows that there is a problem in the right side of the cerebellum. I recall a boy in my class at school who, when writing, always made chewing movements - as though he was chewing food with his mouth open. It was a source of much hilarity for the rest of us (and ridicule for him) when the teacher pointed out that we write with our hands not our mouth! In the early months of life the Palmar Reflex can be activated by sucking movements.
The hands and the mouth are linked together in what is called the Babkin response.
 The hands and the mouth are the baby's main tools for exploration and for expression, and residual reflexes in these areas can affect speech and articulation and fine muscle control.
LONG TERM EFFECTS OF A RETAINED PALMAR REFLEX
1. Poor manual dexterity - the reflex will prevent independent thumb and finger movements.
2. Lack of "pincer" grip, which will affect pencil grip when writing.
3. Speech difficulties - continuing relationship between hand and mouth movement via the Babkin response will prevent the development of independent
muscle control at the front of the mouth, which will then affect articulation. (The Babkin response is demonstrated well in kittens where the action of sucking causes kneading of the paws in time to sucking movements).
4. Palm of the hand may remain hypersensitive to tactile stimulation.
5. Child may make movements with the mouth when trying to write or draw.
The Asymmetrical Tonic Neck Reflex (ATNR)
Chronology - emerges at around 18 weeks in utero and is inhibited or suppressed between 6-8 months after birth, while awake. It persists up to three and a half years while asleep.
Role & description -
 the ATNR fulfils many purposes. It has been suggested that one of its primary functions is to assist in the birth process -
 the rotation of the head allows the shoulders to move, and therefore the baby moves in a spiral down the birth canal.
 The ATNR may also help survival.
 When a baby is placed prone, it should not go into the "frog" position.
 The head should go to one side, with extension of the jaw arm and leg.
 This allows free passage of air.
 The ATNR is the first training ground for eye-hand coordination.
 When a baby is born it can only focus its eyes at about eight inches
 . Outside of that the baby can see movement and shadow, but it cannot focus.
 Through the ATNR, the baby slowly extends the vision from near point fixation to distance, and therefore this is vital for eye-hand coordination training.
Activation -
 head rotation to either side.
 Reaction - the jaw arm would slowly extend, the jaw hand and fingers would also slowly extend.
 The jaw leg would extend, but not as much as the arm.
 The occipital (the back of the head) arm and leg would bend.
 This is the "kick" the mother feels, and it should get stronger and stronger as birth approaches.
Consequences -
 If the ATNR remains strongly present it might affect vision.
 The hand does not want to cross the midline, and as the eyes are locked in to the hands, they do not want to cross the midline either.
 This may mean that, when reading for example, when the eyes get to the midline, they "jump" and the child may lose his/her place.
In crawling, the child is unable to reach and then bend the elbow to drag itself along (it is physiologically impossible to creep, commando style).
 In creeping, the arms need to remain straight, but the ATNR causes a bending of the occipital arm.
 In grasping, when the baby looks at the object, the fingers will want to straighten out. In the older child, it is as though there is an invisible force which causes the arm and hand to straighten whenever the head is turned to one side.
 The child may have to exert a great deal of conscious control when writing - something that should be automatic.
 In addition to the fatigue caused by the effort of fighting the reflex, the child's comprehension can suffer due to the cortex being involved in movement. This can, in turn, affect concentration.
 Judging distance will also be difficult. If present in the legs, walking will be affected, and the child will tend to walk with a stiff leg gait.
When at school, catching a ball (bringing the hands together at the midline) will be affected.
 When the head turns right, the left knee will bend and therefore disturb balance.
 Writing and copying problems will also be seen.
 Gross and fine muscle coordination and eye tracking will also be affected.
 Many children who are articulate and bright just cannot seem to express themselves well in written work.
 It is as though the mind can think and the mouth can speak, but when a motor task is added (writing, for example) the child seems unable to demonstrate the intelligence that we know is there.
 It is clear, therefore, that the ATNR can have a very severe effect.
SYMPTOMS SUGGESTIVE OF A RESIDUAL OR RETAINED ASYMMETRICAL TONIC NECK REFLEX
1. Balance may be affected as a result of head movements to either side.
2. Homolateral (one sided), instead of normal cross pattern movements - e.g. when walking, marching, skipping, etc.
3. Difficulty crossing the midline.
4. Poor ocular pursuit movements, especially at the midline.
5. Mixed laterality (the individual may use left foot, right hand, left ear, or may use left and right hand interchangeably for the same task).
6. Poor handwriting and poor expression of ideas on paper.
7. Visual-perceptual difficulties, particularly in symmetrical representation of figures.
The Tonic Labyrinthine Reflex (TLR)
Chronology - emerges around 3 - 4 months in utero (in flexion, or forwards) and at birth (in extension, or backwards - as in the picture) and is inhibited or suppressed between 3 -4 months after birth (in flexion) and 3 - 4 months to 3 and a half years (in extension).
Role & description -
 This reflex is the baby's way of responding to gravity, hence it is otherwise known as "the baby balance reflex".
 In extension, the TLR helps the baby to straighten out from the flexus habitus position, and it therefore plays a role in the development of muscle tone, a process which also helps to train balance and proprioception (the awareness of the position of the body or limbs).
 The TLR in extension is present at birth, and gets stronger over the next ten days. It has been suggested that when the baby breaks out of flexus habitus, the head has to go back to get into the birth canal.
 With an elective caesarean section, the head has not gone into the TLR in extension position.
 If there is an emergency caesarean, and the head has engaged, the TLR in extension has been activated.
Activation -
 head movement above and below the level of the spine.
Reaction -
 TLR in flexion: if we had a new born baby lying on its back, and its head was gently lifted up above the level of the back, as you lifted the head up the knees would come up and the baby would go into a foetal form (flexus habitus - seen in utero). TLR in extension: if we have a baby lying on its back and you slowly lowered the baby's head below the level of the back, you get the exact opposite from flexion.
 As the head goes back, so the legs and the feet stretch out, and the arms and hands stretch out into a near crucifixion position.
Consequences -
 There can be a devastating effect on many functions if the TLR remains present - eyes, balance and proprioception to name but a few. Head movement can affect muscle tone ('floppy' child - low or weak muscle tone), and this can cause a distortion in the centre of balance.
 The brain will lack a secure reference point from which to judge space, depth, distance and speed, and this, in addition to causing problems with directions such as left, right, up, down, etc, can lead to difficulty with spatial tasks.
 The ability to track smoothly and evenly with the eyes only comes as the TLR in extension is inhibited, and the continued presence of the TLR prevents the proper emergence of the Head Righting Reflexes.
 As the eyes and ears operate on the same circuit of the brain (even sharing cranial nerves), poor visual information will affect balance, and poor balance will affect vision.
SYMPTOMS SUGGESTIVE OF A STRONGLY RESIDUAL TONIC LABYRINTHINE REFLEX FORWARDS
1. Poor posture - stoop.
2. Hypotonus - weak muscle tone.
3. Vestibular related problems:
a. poor sense of balance.
b. propensity to get car sick.
4. Dislike of sporting activities, physical education classes, running, etc.
5. Oculomotor dysfunctions:
a. Visual-perceptual difficulties.
b. Spatial problems.
6. Poor sequencing skills.
7. Poor sense of time.
SYMPTOMS OF A STRONGLY RESIDUAL TONIC LABYRINTHINE REFLEX BACKWARDS
1. Poor posture - tendency to walk on toes.
2. Poor balance and coordination.
3. Hypertonus - stiff, jerky movements because the extensor muscles exert greater influence than the flexor muscles.
4. Vestibular related problems:
a. Poor sense of balance.
b. Tendency to motion sickness.
5. Oculomotor dysfunction:
a. Visual-perceptual difficulties.
b. Spatial perception problems.
6. Poor sequencing skills.
7. Poor organisation skills.
The Symmetrical Tonic neck Reflex (STNR)
Chronology - emerges around 9 - 11 months after birth and is inhibited or suppressed at about one year.
Role & description -
 it has a very short, significant life.
 This is virtually the cat reflex.
 After the baby, ideally in development, has crawled on its stomach, around 9 - 11 months the developing brain releases the reflex to allow the baby to begin to defy gravity.
 The sole task of the STNR is to get the child to begin to defy gravity.
Activation -
 from a 'kneeling' position, either movement of the baby's head upwards or downwards.
Reaction -
 every time the baby looks up the bottom goes back onto the ankles, and every time the baby looks down the elbows bend and the head virtually hits the floor.
Consequences
 - if it remains it impedes, in some way, creeping on hands and knees. It is impossible to crawl if the STNR persists, and the child will be a "bottom hopper".
 If you test just for the STNR alone, it may be a good indication of neurological dysfunction. In around 75% of LD children there is a retained STNR.
 When writing, the elbows bend and the head goes nearer and nearer to the writing surface.
 It also makes them messy eaters. When they are using a spoon and they put their head down, they do not have control over the hand and head movement, and therefore spill as much food as they put in their mouth.
 These children tend to compensate by lifting the spoon up and putting their head down.
 The STNR has been associated with reading, writing and concentration problems. It will also affect copying and spelling and has a definite, noticeable effect on posture and movement.
It is very closely tied in with the TLR and, in addition to affecting swimming, it is usually noted in the so called "clumsy child".
SYMPTOMS SUGGESTIVE OF A STRONGLY RESIDUAL SYMMETRICAL TONIC NECK REFLEX
1. Poor posture.
2. Tendency to "slump" when sitting, particularly at a desk or table.
3. Simian (ape like) walk.
4. "W" leg position when sitting on the floor.
5. Poor eye hand coordination:
a. Messy eater.
b. "Clumsy child" syndrome.
6. Difficulties with readjustment of binocular vision (cannot change focus easily from blackboard to desk).
7. Slowness at copying tasks.
8. Poor swimming skills.
The Segmental Rolling Reflex (SRR)
Chronology - emerges around 6 - 10 months after birth and remains present throughout life.
Role & description -
 The Segmental Rolling Reflexes (also known as "neck on body reactions") allow the baby to roll over.
 For example, when lying on the tummy, the baby first begins to learn to hold the head up - then the upper torso is raised - and eventually the ability to roll over and up into a sitting position follows, in accordance with the "cephalo-caudal" developmental law (from head to toe).
Activation -
 in either prone or supine, raise either the shoulder or the knee and move it across the midline towards the other side of the body.
Reaction -
 when raising the shoulder the knee on the same side should begin to bend. When raising the knee, the shoulder and arm should begin to roll also. If you bend the knee up and you push the knee slowly across the midline, the arm/body should follow through.
 This allows you to roll over.
Consequences -
 many children with coordination problems and dyspraxia do not have this.
 It is the ability to use one part of the body without other parts of the body on the same side locking in.
 So the SRR gives us that smooth, good, erect coordination of the body and facilitates fluidity of movement.
SYMPTOMS SUGGESTIVE OF AN ABSENCE OF THE AMPHIBIAN AND SEGMENTAL ROLLING REFLEXES
1. Lack of cross pattern crawling and creeping.
2. Hypertonus (high muscle tone) affecting gross muscle coordination.
3. Difficulty effecting positional changes.
4. Lack of fluidity of movement.

Oral-Sensory
Age: Infancy -- Birth to 1 year
Conflict: Trust vs. Mistrust
Important Event: Feeding
|
Description:
 The important event in this stage is feeding. According to Erikson, the infant will develop a sense of trust only if the parent or caregiver is responsive and consistent with the basic needs being meet. The need for care and food must be met with comforting regularity. The infant must first form a trusting relationship with the parent or caregiver, otherwise a sense of mistrust will develop.
Elements for a positive outcome:
 The infant's need for care, familiarity, comfort and nourishment are met. Parental consistency and responsiveness is essential for the sense of trust to develop.
Elements for a negative outcome:
 Babies who are not securely attached to their mothers are less cooperative and more aggressive in their interactions with their mothers. As they grow older, they become less competent and sympathetic with peers. They also explore their environment with less enthusiasm and persistence.
Examples:
 Babies will begin to understand that objects and people exist even when they cannot see them. This is where trust becomes important.
Muscular-Anal
Age: Toddler period -- 1 to 2 years
Conflict: Autonomy vs. Doubt
Important Event: Toilet Training
|
Description:
 According to Erikson, self control and self confidence begin to develop at this stage. Children can do more on their own. Toilet training is the most important event at this stage. They also begin to feed and dress themselves. This is how the toddler strives for autonomy. It is essential for parents not to be overprotective at this stage. A parent's level of protectiveness will influence the child's ability to achieve autonomy. If a parent is not reinforcing, the child will feel shameful and will learn to doubt his or her abilities. "Erikson believes that children who experience too much doubt at this stage will lack confidence in their powers later in life"" (Woolfolk, 1987).
Elements for a positive outcome:
 The child must take more responsibility for his or her own feeding, toileting, and dressing. Parents must be reassuring yet avoid overprotection.
Elements for a negative outcome:
 If parents do not maintain a reassuring, confident attitude and do not reinforce the child's efforts to master basic motor and cognitive skills, children may begin to feel shame; they may learn to doubt their abilities to manage the world on their own terms. Children who experience too much doubt at this stage will lack confidence in their own powers throughout life.
Examples:
 In this stage children begin to assume important responsibilities for self-care like feeding, toileting, and dressing.
Locomotor
Age: Early Childhood -- 2 to 6 years
Conflict: Initiative vs. Guilt
Important Event: Independence
|
Description:
 The most important event at this stage is independence. The child continues to be assertive and to take the initiative. Playing and hero worshipping are an important form of initiative for children. Children in this stage are eager for responsibility. It is essential for adults to confirm that the child's initiative is accepted no matter how small it may be. If the child is not given a chance to be responsible and do things on their own, a sense of guilt may develop. The child will come to believe that what they want to do is always wrong.
Elements for a positive outcome:
 In order for a positive outcome in this stage, the child must learn to accept without guilt, that there are certain things not allowed. Children must be guilt free when using imagination. They must be reassured that it is okay to play certain adult roles.
Elements for a negative outcome:
 If children are not allowed to do things on their own, a sense of guilt may develop and they may come to believe that what they want to do is always wrong.
Examples:
 A four year old passing tools to a parent who is fixing a bicycle. Children at this stage will worship heroes. Pretend games are also common.
: Latency
Age: Elementary and Middle School Years -- 6 to 12 years
Conflict: Industry vs. Inferiority
Important Event: School
|
Description:
 "In this stage children are learning to see the relationship between perseverance and the pleasure of a job completed" ~ANDERSMD/ERIK/refers.HTML" \l "Woolfolk," (Woolfolk, 1987). The important event at this stage is attendance at school. As a student, the children have a need to be productive and do work on their own. They are both physically and mentally ready for it. Interaction with peers at school also plays an imperative role of child development in this stage. The child for the first time has a wide variety of events to deal with, including academics, group activities, and friends. Difficulty with any of these leads to a sense of inferiority.
Elements for a positive outcome:
 It is essential for the child at this stage to discover pleasure in being productive and the need to succeed. The child's relationship with peers in school and the neighborhood become increasingly important.
Elements for a negative outcome:
 Difficulty with the child's ability to move between the world at home and the world of peers can lead to feeling of inferiority.
Examples:
 In this stage children want to do productive work on their own. Students are able to water class plants, collect and distribute materials for teacher, and keep records of forms for teacher
Adolescence
Age: Adolescence --12 to 18 years
Conflict: Identity vs. Role Confusion
Important Event: Peer relationships
|
Description:
 At this stage, adolescents are in search of an identity that will lead them to adulthood. Adolescents make a strong effort to answer the question "Who am I?" Erikson notes the healthy resolution of earlier conflicts can now serve as a foundation for the search for an identity. If the child overcomes earlier conflicts they are prepared to search for identity. Did they develop the basic sense of trust? Do they have a strong sense of industry to believe in themselves?
Elements for a positive outcome:
 The adolescent must make a conscious search for identity. This is built on the outcome and resolution to conflict in earlier stages.
Elements for a negative outcome:
 If the adolescent can not make deliberate decisions and choices, especially about vocation, sexual orientation, and life in general, role confusion becomes a threat.
Examples:
 Adolescents attempt to establish their own identities and see themselves as separate from their parents.
Young Adulthood
Age: Young Adulthood -- 19 to 40 years
Conflict: Intimacy vs. Isolation
Important Event: Love relationships
|
 Description:
 In this stage, the most important events are love relationships. Intimacy refers to one's ability to relate to another human being on a deep, personal level. An individual who has not developed a sense of identity usually will fear a committed relationship and may retreat into isolation. It is important to mention that having a sexual relationship does not indicate intimacy. People can be sexually intimate without being committed and open with another. True intimacy requires personal commitment. However, mutual satisfaction will increase the closeness of people in a true intimate relationship.
Elements for a positive outcome:
 The young adult must develop intimate relationships with others. Not resolving this conflict leaves the young adult feeling isolated. The young adult must be willing to be open and committed to another individual.
Elements for a negative outcome:
 An individual may retreat into isolation if a sense of identity is not developed and will fear a committed relationship.
Examples:
 Giving and sharing with an individual without asking what will be received in return.
Middle Adulthood
Age: Middle adulthood -- 40 to 65 years
Conflict: Generativity vs. Stagnation
Important Event: Parenting
|
Description:
 In this stage generativity refers to the adult's ability to care for another person. The most important event in this stage is parenting. Does the adult have the ability to care and guide the next generation? Generativity has a broader meaning then just having children. Each adult must have some way to satisfy and support the next generation. According to Erikson, "A person does best at this time to put aside thoughts of death and balance its certainty with the only happiness that is lasting: to increase, by whatever is yours to give, the good will and higher order in your sector of the world" " (Erikson, 1974).

Maturity
Age: Late Adulthood -- 65 years to death
Conflict: Integrity vs. Despair
Important Event: Reflection on
and acceptance of one's life
|
Description:
The most important event at this stage is coming to accept one's whole life and reflecting on that life in a positive manner. According to Erikson, achieving a sense of integrity means fully accepting oneself and coming to terms with the death. Accepting responsibility for your life and being able to undo the past and achieve satisfaction with self is essential. The inability to do this results in a feeling of despair.
 Elements for a positive outcome:
The adult feels a sense of fulfillment about life and accepts death as an unavoidable reality.
 Elements for a negative outcome:
Individuals who are unable to obtain a feeling of fulfillment and completeness will despair and fear death.
 Examples:
An aged person may find it necessary to reflect and analyze what they have accumulated throughout life and decide what offspring will receive from them upon death.
