Theories of Human Development


Freud's Psychoanalytic Theory
Sigmund Freud (1856-1939) challenged prevailing notions of human nature and human development by proposing that we are driven by motives and emotions on which we are largely unaware and that we are shaped by our earliest experiences in life.


Freud didn't exactly invent the idea of the conscious versus unconscious mind, but he certainly was responsible for making it popular. The conscious mind is what you are aware of at any particular moment, your present perceptions, memories, thoughts, fantasies, feelings, what have you. Working closely with the conscious mind is what Freud called the preconscious, what we might today call "available memory:" anything that can easily be made conscious, the memories you are not at the moment thinking about but can readily bring to mind. Now no-one has a problem with these two layers of mind. But Freud suggested that these are the smallest parts!

The largest part by far is the unconscious. It includes all the things that are not easily available to awareness, including many things that have their origins there, such as our drives or instincts, and things that are put there because we can't bear to look at them, such as the memories and emotions associated with trauma.

According to Freud, the unconscious is the source of our motivations, whether they be simple desires for food or sex, neurotic compulsions, or the motives of an artist or scientist. And yet, we are often driven to deny or resist becoming conscious of these motives, and they are often available to us only in disguised form. We will come back to this.

The id, the ego, and the superego

Freudian psychological reality begins with the world, full of objects. Among them is a very special object, the organism. The organism is special in that it acts to survive and reproduce, and it is guided toward those ends by its needs -- hunger, thirst, the avoidance of pain, and sex.

A part -- a very important part -- of the organism is the nervous system, which has as one of its characteristics a sensitivity to the organism's needs. At birth, that nervous system is little more than that of any other animal, an "it" or id. The nervous system, as id, translates the organism's needs into motivational forces called, in German, Triebe, which has been translated as instincts or drives. Freud also called them wishes. This translation from need to wish is called the primary process.

The id works in keeping with the pleasure principle, which can be understood as a demand to take care of needs immediately. Just picture the hungry infant, screaming itself blue. It doesn't "know" what it wants in any adult sense; it just knows that it wants it and it wants it now. The infant, in the Freudian view, is pure, or nearly pure id. And the id is nothing if not the psychic representative of biology.

Unfortunately, although a wish for food, such as the image of a juicy steak, might be enough to satisfy the id, it isn't enough to satisfy the organism. The need only gets stronger, and the wishes just keep coming. You may have noticed that, when you haven't satisfied some need, such as the need for food, it begins to demand more and more of your attention, until there comes a point where you can't think of anything else. This is the wish or drive breaking into consciousness.

Luckily for the organism, there is that small portion of the mind we discussed before, the conscious, that is hooked up to the world through the senses. Around this little bit of consciousness, during the first year of a child's life, some of the "it" becomes "I," some of the id becomes ego. The ego relates the organism to reality by means of its consciousness, and it searches for objects to satisfy the wishes that id creates to represent the organisms needs. This problem-solving activity is called the secondary process.

The ego, unlike the id, functions according to the reality principle, which says "take care of a need as soon as an appropriate object is found." It represents reality and, to a considerable extent, reason.

However, as the ego struggles to keep the id (and, ultimately, the organism) happy, it meets with obstacles in the world. It occasionally meets with objects that actually assist it in attaining its goals. And it keeps a record of these obstacles and aides. In particular, it keeps track of the rewards and punishments meted out by two of the most influential objects in the world of the child -- mom and dad. This record of things to avoid and strategies to take becomes the superego. It is not completed until about seven years of age. In some people, it never is completed.

There are two aspects to the superego: One is the conscience, which is an internalization of punishments and warnings. The other is called the ego ideal. It derives from rewards and positive models presented to the child. The conscience and ego ideal communicate their requirements to the ego with feelings like pride, shame, and guilt.

It is as if we acquired, in childhood, a new set of needs and accompanying wishes, this time of social rather than biological origins. Unfortunately, these new wishes can easily conflict with the ones from the id. You see, the superego represents society, and society often wants nothing better than to have you never satisfy your needs at all!

Anxiety

Freud once said "life is not easy!"

The ego -- the "I" -- sits at the center of some pretty powerful forces: reality; society, as represented by the superego; biology, as represented by the id. When these make conflicting demands upon the poor ego, it is understandable if it -- if you -- feel threatened, feel overwhelmed, feel as if it were about to collapse under the weight of it all. This feeling is called anxiety, and it serves as a signal to the ego that its survival, and with it the survival of the whole organism, is in jeopardy.

Freud mentions three different kind of anxieties: The first is realistic anxiety, which you and I would call fear. Actually Freud did, too, in German. But his translators thought "fear" too mundane! Nevertheless, if I throw you into a pit of poisonous snakes, you might experience realistic anxiety.

The second is moral anxiety. This is what we feel when the threat comes not from the outer, physical world, but from the internalized social world of the superego. It is, in fact, just another word for feelings like shame and guilt and the fear of punishment.

The last is neurotic anxiety. This is the fear of being overwhelmed by impulses from the id. If you have ever felt like you were about to "lose it," lose control, your temper, your rationality, or even your mind, you have felt neurotic anxiety. Neurotic is actually the Latin word for nervous, so this is nervous anxiety. It is this kind of anxiety that intrigued Freud most, and we usually just call it anxiety, plain and simple.

The defense mechanisms

Freud believed that defence mechanisms are important to understand the working of personality. Defence mechanisms are the ego’s protective measures for reducing anxiety by unconsciously distorting reality. According to Freud, the conflicting demands of the personality structures produce anxiety. The ego calls on a number of strategies to resolve the conflict between its demands for reality ,the wishes of the id and the constraints of the superego. Some of the most common defence mechanisms are repression, compensation, rationalization, regression, displacement , etc.

Psychosexual Developmental stages

As I said earlier, for Freud, the sex drive is the most important motivating force. In fact, Freud felt it was the primary motivating force not only for adults but for children and even infants. When he introduced his ideas about infantile sexuality to the Viennese public of his day, they were hardly prepared to talk about sexuality in adults, much less in infants!

It is true that the capacity for orgasm is there neurologically from birth. But Freud was not just talking about orgasm. Sexuality meant not only intercourse, but all pleasurable sensation from the skin. It is clear even to the most prudish among us that babies, children, and, of course, adults, enjoy tactile experiences such as caresses, kisses, and so on.

Freud noted that, at different times in our lives, different parts of our skin give us greatest pleasure. Later theorists would call these areas erogenous zones. It appeared to Freud that the infant found its greatest pleasure in sucking, especially at the breast. In fact, babies have a penchant for bringing nearly everything in their environment into contact with their mouths. A bit later in life, the child focuses on the anal pleasures of holding it in and letting go. By three or four, the child may have discovered the pleasure of touching or rubbing against his or her genitalia. Only later, in our sexual maturity, do we find our greatest pleasure in sexual intercourse. In these observations, Freud had the makings of a psychosexual stage theory.

The oral stage lasts from birth to about 18 months. The focus of pleasure is, of course, the mouth. Sucking and biting are favorite activities.

The anal stage lasts from about 18 months to three or four years old. The focus of pleasure is the anus. Holding it in and letting it go are greatly enjoyed.

The phallic stage lasts from three or four to five, six, or seven years old. The focus of pleasure is the genitalia. Masturbation is common.

The latent stage lasts from five, six, or seven to puberty, that is, somewhere around 12 years old. During this stage, Freud believed that the sexual impulse was suppressed in the service of learning. I must note that, while most children seem to be fairly calm, sexually, during their grammar school years, perhaps up to a quarter of them are quite busy masturbating and playing "doctor." In Freud's repressive era, these children were, at least, quieter than their modern counterparts.

The genital stage begins at puberty, and represents the resurgence of the sex drive in adolescence, and the more specific focusing of pleasure in sexual intercourse. Freud felt that masturbation, oral sex, homosexuality, and many other things we find acceptable in adulthood today, were immature.


ERIK ERIKSON’S THEORY




Sigmund Freud is probably the most familiar name that comes to mind when one thinks of famous psychologists. His basic foundation theories of instinct, phallic symbol obsession and oedipal complexes are prevalent in almost every artistic aspect of our culture. However, it was a friend and fellow psychoanalyst of Freud’s, Erik Erickson, who created one of the major theories that open a window to the development of everything that makes us who we are on the inside. It is referred to as Erickson’s Theory of Human Development and it simplifies the complex topic of human personality.

First, let’s talk about the man himself. Erik Homberger was born in Frankfurt, Germany in 1902. The conditions under which he began life give a great deal of insight into his obsession with identity. He was challenged with it from the stat. His parents weren’t married and his Danish father left before Erik was born. His Jewish mother married Erik’s pediatrician when he was three. Erik had Nordic features; he was tall, blond and had blue eyes. Neither the Jewish children at temple nor the German children at school accepted him.

As he grew up, psychology and art began to interest Erik and led him to various institutes including one where he was psychoanalyzed by Anna Freud, wife of Sigmund. Both later became close friends to Erickson. When the Nazis came to power, Erik moved to Boston where he studied child psychoanalysis and was influenced by many psychologists and anthropologists Mead, but many famous psychologists and anthropologists.

He is considered a Freudian ego-psychologist, meaning he takes the basic foundation of Freud’s theories, but veers away by focus on social and cultural orientation. Erickson’s theory closely ties personality growth with parental and societal values. His 1950 book, Childhood and Society, is considered a classic in its field.

There are eight stages of human development, each focusing on a different conflict that we need to solve in order to development successfully into the next stage of our lives. The idea is that if we don’t resolve each stage or we choose the wrong of two choices, our ability to deal with the consecutive stages is impaired and the failure will return to us at some point later in life.

Stage One: Oral Sensory
Ages: Birth To 12-18 Months
Conflict: Trust vs Mistrust

The infant’s bond with their primary caregiver is about trust and love. The connection with that person (usually Mommy) allows them to feel like they are safe and can rely on the person who is basically the only thing they know. It’s about touch and being there and can be seen in that tender stare they give you as you feed them.

Stage Two: Muscular Anal
Ages: 18 Months To 3 Years
Conflict: Autonomy vs Doubt

This stage focuses on self control and self confidence and Erickson gives toilet training as the greatest example of this conflict. He also points out that this is the stage where an overprotective parent can do the most damage. The child wants autonomy. We’re all familiar with the two hour wait because they have to tie their own shoes. We wait because in this stage, failure to reinforce these efforts will lead the child to doubt themselves and your trust in them.

Stage Three: Locomotor
Ages: 3 To 6 Years
Conflict: Initiative vs Guilt

This is all about independence and letting the child exert his/her initiative. This is the stage where carrying your car keys or helping Mommy in any way possible is very important. They are developing a sense of responsibility and limitations. They will try to do things they can’t and the response the parent gives them, encouragement or refusal, will allow the child to understand limitations without guilt.

Stage Four: Latency
Ages: 6 To 12 Years
Conflict: Industry vs Inferiority
This is about completion. Before this stage, we’re all familiar with the child beginning to do something, but then snap; he drops it and is on to something else. In this stage, completion and the pleasure it brings becomes crucial. This is greatly influenced by their introduction to school beyond day care. It is the coming together of mental and physical capabilities as well. Parents need to encourage their child to handle the different experiences of a home atmosphere and the atmosphere at school among others.

Stage Five: Adolescence
Ages: 12 To 18 Years
Conflict: Identity vs Role Confusion

This stage could be a book in itself; the teenage years. They are hard on everyone, but especially the child herself. They are aware that they will become a contributor to society (industry) and the search for who they are drives their actions and thoughts. The desire to know what it is they want and believe separate from what they’ve adopted from their parents is crucial to their self confidence.

Stage Six: Young Adulthood
Ages: 19 To 40 Years
Conflict: Psychosocial Development
Love relationships dominate this stage for all of us and relies heavily on our ability to solve the conflicts faced in stage five. Can you be intimate? Can you be open? Can you commit? Intimacy is referred to as the ability to make a personal commitment and doesn’t necessarily mean sex. Personal commitment, met with mutual satisfaction, make this a successful stage. If unable to handle this stage, an adult will resort to isolation.

Stage Seven: Middle Adulthood
Ages: 40 To 65 Years
Conflict: Generativity vs Stagnation
The words are getting bigger, but stay with me. Generativity is our ability to care for someone else which is mostly displayed in parenting. Specifically, it’s the ability to direct someone into society and the next generation. We don’t focus on death, but we begin to understand that we are high in the order of society and owe society something. If we haven’t dealt with our previous conflicts, we become stagnant and our lives won’t exhibit anything we can look back on.

Stage Eight: Maturity
Ages: 65 to Death
Conflict: Ego Integrity vs Despair

This is when we begin to reflect on our lives, accepting it for what it was. If we have done well in previous stages, especially stage seven, we can feel a sense of fulfillment and accept death as an unavoidable reality with dignity. If we haven’t done well, we can be filled with regret, despair over the time running out and fear of death.

When you read through the stages, it’s impossible not to identify them as you’ve experienced them or as you see your children experiencing them. However, Erickson’s theory is not without critics. Many say that it is too focused on infancy and childhood and isn’t very helpful for later in life. Others say it really applies to boys and not girls using Erickson’s belief (Freudian) that boys and girls naturally develop different personalities.

In general, Erickson’s Theory of Human Development is widely accepted and plays a major role in all human and psychological development studies and theories. The best advice is to use the theory as a framework or map for understanding and identifying what issues/conflicts unresolved lead to current behavior and preparing for the stages to come.




Piaget's Cognitive Developmental Theory
Jean Piaget (1896-1980) viewed intelligence as a process that helps an organism adapt to

its environment and proposed four major periods of cognitive development.



Piaget's Stages of Cognitive Development

Children go through a series of cognitive developments, marked by stages. These stages were not pinpointed by a psychologist, however. They were determined by developmental biologist Jean Piaget. His stages of development can be helpful in determining what reasoning power you can expect a child of a certain age to have. For example, kids under the age of seven think very differently than a 12 year old.

Piaget determined that infants from birth to 24 months old experience the sensory motor stage. At this age, children experience the world around them through their sense of touch. They touch everything, and their reflexive behaviors become more complex until they are more intentional. Towards the end of this stage, the child develops problem-solving sequences.

From the ages of 2 to 7, children experience the preoperational period, according to Piaget. Although speech remains egocentric, the child begins to use verbal representation. The speech becomes less egocentric with time. During this stage, the child also begins to grasp symbolism and transductive reasoning. Additionally, the child doesn't grasp principles, just simple do's and don'ts for guiding their behavior.

From the ages of 7 to 11, children have an easier time grasping organized and logical thought. Children are able to grasp multiple classification tasks, and logical sequences. Children can also sort objects into logical categories (rather than superficial ones like color) and grasp reversibility (like reversible operations in math).

Children can also grasp conservation during this stage. They are able to learn that an object isn't always the way it appears. Kids also develop the ability to imagine "what ifs" (what if 'x' happens, what if 'y' happens, etc.).

Additionally, Piaget determined that children's operational thought is limited during this stage. They can engage in logical thought about an object only if they can manipulate it. Once a child progresses to the next stage, they can grasp logical thought about an object without the object ever being present.




Vygotsky's Theory of Cognitive Development

The Socio-Cultural Perspective





Psychologist Lev Vygotsky proposed that children learn through interactions with their surrounding culture. This theory, known as the socio-cultural perspective, states that the cognitive development of children and adolescents is enhanced when they work in their Zone of Proximal Development (ZPD for short). To reach the ZPD, children need the help of adults or more competent individuals to support or scaffold them as they are learning new things.

According to Vygotsky’s theory, children can do more with the help and guidance of an adult or other person more experienced person than they can do by themselves. The Zone of Proximal Development defines skills and abilities that are in the process of developing. The ZPD is the range of tasks that one cannot yet perform independently, but can accomplish with the help of a more competent individual. For example, a child might not be able to walk across a balance beam on her own, but she can do so while holding her mother’s hand. Since children are always learning new things, the ZPD changes as new skills are acquired.

In the example above, the child’s mother provided assistance to the child. The mother acted as a scaffold in that situation. Scaffolding is the structure or guidance of a more experienced person. There are many different ways of scaffolding, including breaking the task down into smaller steps, providing motivation, and providing feedback about progress as the person progresses.

As time goes by, the adult will continually adjust the amount of support they give in response to the child’s level of performance. For example, as the child becomes more confident in her balance, her mother can go from holding both hands, to eventually holding one hand, and eventually she can stop holding her hand. The child will soon be able to walk unassisted. Therefore, scaffolding instills the skills necessary for independent problem solving in the future.

In conclusion, Vygotsky’s theory of cognitive development states that interactions with other people are essential for maximum cognitive development to occur.
