  1. 1. Dr. Magda FahmyProfessor of PsychiatrySuez Canal University
  2. 2. Kohlberg’s Theory of MoralDevelopment Moral development is the development of theindividual’s sense of right and wrong. A high level of moral development is built on afoundation of cognitive development.
  3. 3.  The philosophers Plato and Immanuel Kant believedthat the moral sense is inborn. On the other hand, the philosophers Aristotle andJohn Locke assumed that moral development requireslearning and experience. Kohlberg’s approach tends to favor the learninghypothesis. Human beings acquire a moral sense by learning tothink clearly, by the example of role models, and bysocial reinforcement.
  4. 4. Kohlberg’s Theory of MoralDevelopmentthere are three principal levels of moral development:(1) the premoral level (Pre-Conventional)(2) the conventional level, and(3) the principled level (Post-Conventional) .(There are six stages associated with the threelevels, two stages to each level).
  5. 5. Level 1 (Pre-Conventional)1. Obedience and punishment orientation(How can I avoid punishment?)2. Self-interest orientation(Whats in it for me?)(Paying for a benefit)(A child with preconventional morality has not yet adopted orinternalized societys conventions regarding what is right orwrong, but instead focuses largely on external consequences thatcertain actions may bring)
  6. 6. Level 2 (Conventional)3. Interpersonal accord and conformity(Social norms)(The good boy/good girl attitude)4. Authority and social-order maintaining orientation(Law and order morality)
  7. 7. Level 3 (Post-Conventional)5. Social contract orientation6. Universal ethical principles(Principled conscience)
  8. 8.  The premoral level (Pre-Conventional) is associatedwith early childhood (from about two to seven yearsold). The theme of this level is powerorientation, meaning that to a child thinking at thislevel, “might makes right.” The parents are seen as“right” because they are bigger and stronger than thechild.
  9. 9.  In Stage one (obedience and punishmentdriven), individuals focus on the direct consequencesof their actions on themselves. For example, an action is perceived as morally wrongbecause the perpetrator is punished. The worse thepunishment for the act is, the more "bad" the act isperceived to be.
  10. 10.  Stage two (self-interest driven) all actions have the purpose of serving the individualsown needs or interests. He is "egocentric", lacking recognition that otherspoints of view are different from ones own The worlds perspective is often seen as morallyrelative.
  11. 11.  Five-year-old Kenneth is considering whether or nothe should steal a one-dollar bill from his mother’spurse. His hesitation, if there is any, is based on thefear of being caught, not on guilt. He is amoral, meaning that he has no actual moralsense, no internal feeling that he is wrong to dosomething that is forbidden.
  12. 12.  The conventional level is associated with latechildhood and adolescence (seven to eighteen yearsold). Also, many, probably most, adults continue to operateat the conventional level, never progressing to theprincipled level. The theme of the level is “law and order.” Right isright because human beings have codes of conductand written laws.
  13. 13.  Fifteen-year-old Sally identifies with her family. Thefamily has a certain religion, certain attitudes, andwell-defined notions of what is and is not sociallyacceptable behavior. Sally doesn’t question the family’svalues. She doesn’t examine or challenge them. She isoperating at the conventional level. Thirty-four-year-old Kelvin pays his taxes, has earnedan honorable discharge from the army, and thinks ofhimself as a “good citizen.” Kelvin, like Sally, is operating at the conventional level.
  14. 14.  In Stage three (interpersonal accord and conformitydriven) Individuals are receptive to approval or disapprovalfrom others as it reflects societys accordance with theperceived role. Stage three reasoning may judge the morality of anaction by evaluating its consequences in terms of apersons relationships, which now begin to includethings like respect, gratitude and the “golden role” :"I want to be liked.
  15. 15.  In Stage four (authority and social order obediencedriven), it is important to obey laws and socialconventions because of their importance inmaintaining a functioning society. A central ideal or ideals often prescribe what is rightand wrong, such as in the case of fundamentalism. If one person violates a law, there is an obligation and aduty to uphold ( ) laws and rules.
  16. 16.  The principled level (Post-Conventional) isassociated with a relatively small percentage of adults. These are people who think for themselves about whatis right and wrong. They are not chaotic in theirthought processes. They are logical and clear sighted. In certain cases, they may decide that a law or a groupof laws are unjust, and they may rebel. It is clear that not all adults outgrow even the first level, the premorallevel. Dictators who rule by brute force, who punish in accordance withtheir personal whims, operate at the premoral level.
  17. 17.  In Stage five (social contract driven), the world is viewedas holding different opinions, rights and values. Such perspectives should be mutually respected as uniqueto each person or community. Laws are regarded as social contracts rather than rigidedicts. Those that do not promote the general welfare should bechanged when necessary to meet “the greatest good forthe greatest number of people”. This is achieved through majority decision, andinevitable compromise. Democratic government isbased on stage five reasoning.
  18. 18.  In Stage six (universal ethical principlesdriven), moral reasoning is based on abstractreasoning using universal ethical principles. Laws are valid only insofar as they are grounded injustice, and a commitment to justice carries with it anobligation to disobey unjust laws. The individual acts because it is right, and not becauseit is instrumental, expected, legal, or previously agreedupon.
  19. 19. Erikson’s Theory of PsychosocialDevelopment Erik Erikson (1902–1994) was personally trained byFreud, and maintained respect for Freud’s theory.However, he expanded Freud’s concept ofpsychosexual development to include psychosocialdevelopment. Psychosocial development refers to thecharacteristic ways in which the individual learns torespond to other people.
  20. 20.  The term social world is often used to refer to theconstellation of other human beings in ourenvironment—parents, siblings, teachers, friends, sweethearts andlovers, husbands and wives, and coworkers.
  21. 21. Erikson, eight stages ofpsychosocial development(1) trust versus mistrust,(2) autonomy versus shame and doubt,(3) initiative versus guilt,(4) industry versus inferiority,(5) identity versus role confusion,(6) intimacy versus isolation,(7) generativity versus self-absorption, and(8) integrity versus despair. (TA4IGI) At each stage of development, the individual ischallenged by life to form the positive trait.
  22. 22. Erikson, eight stages ofpsychosocial development1. Trust versus mistrust is associated with infancy(birth to two years old). An infant with a sense of trust tends to thrive andexpects good things to happen. Conversely, an infant with a sense of mistrustsometimes displays a failure to thrive syndrome. A lackof interest in the surrounding world and poorhealth, associated with mistrust, are characteristics ofinfantile depression. In general, affection and positive reinforcement tendto bring forth the positive traits.
  23. 23. Erikson, eight stages ofpsychosocial development2. Autonomy versus shame and doubt is associatedwith toddlerhood (two to three years old). A toddler with a sense of autonomy will be interestedin exploring the immediate world and display aninterest in novel stimulation. A certain amount ofself-direction will emerge. Conversely, a toddler with a sense of shame and doubtwill tend to hold back, to seem shy, and to lack selfconfidence.
  24. 24. Erikson, eight stages ofpsychosocial development3. Initiative versus guilt is associated with the preschoolperiod (three to six years old). A preschooler start a project with a sense of initiative willbe likely to and see it through to completion. For example, four-year-old Rosalyn says, “I’m going to color all of thepictures in my coloring book.” If adults discourage the pursuit of independent activities ordismiss them as silly and bothersome, children developguilt about their needs and desires. A preschooler with a sense of guilt is hesitant, does notseek challenges, and holds back when an opportunityfor self-expression presents itself.
  25. 25. Erikson, eight stages ofpsychosocial development4. Industry versus inferiority is associated withmiddle childhood (six to twelve years old). A child with a sense of industry will show an interestin school, study, complete homework, agree to doreasonable chores, and in general displayresponsible behavior. A child with a sense of inferiority will avoidstudying, homework, and chores. The child obtains nosatisfaction from these activities, particularly if thechild often obtains poor grades or receives too muchparental criticism.
  26. 26. Erikson, eight stages ofpsychosocial development5. Identity versus role confusion is associated withadolescence (twelve to eighteen years old). An adolescent with an identity has a sense of direction inlife. He or she already thinks in terms of a particularvocational area, has fairly well defined plans for thefuture, and a high level of self-esteem. Although goalsare not yet attained, they seem clearly desirable andpossible. Conversely, an adolescent suffering from role confusionimagines no particular pathway in life and dreams of nowell-shaped future. On the contrary, the future seemsobscure and formless.
  27. 27. Erikson, eight stages ofpsychosocial development6. Intimacy versus isolation is associated with youngadulthood. This starts when adolescence is over, usuallyaround the age of eighteen. However, in practice, young adulthood may be deferred fora number of years until an identity has been attained. Thepresent stage and the future stages to be discussed will notbe identified with particular years. Intimacy is the capacity to form a close emotional bondwith another person, often a marriage partner. Isolation exists when an individual treats anotherindividual like a thing, an object to be manipulated andtaken advantage of.
  28. 28. Erikson, eight stages ofpsychosocial development7. Generativity versus self-absorption is associatedwith adulthood. An adult with the trait of generativityis capable of productive work. Usually he or she willspend many years employed in a vocation or a well-defined social role (e.g., parent). Generativity is linked to giving something of value tothe world. The adult with this trait contributes in someway to the welfare of others. Self-absorption is concerned only with his or her ownwelfare. Taking, not giving, is the theme of the person’slife. He or she is, in essence, a sort of parasite.
  29. 29. Erikson, eight stages ofpsychosocial development8. Integrity versus despair is associated with old age. Anolder person with the trait of integrity can faceapproaching death with a certain amount ofacceptance. There is relative peace of mind because the individual isconvinced that his or her life was spent well, that it hadmeaning. An older person in a state of despair has a sense ofdesperation as life draws to its inevitable end. There is verylittle peace of mind because the individual is thinking thathe or she needs a second chance, an opportunity to get liferight.
  30. 30.  Although the individual has very little control over thefirst few stages of life, with adolescence and adulthoodthere is greater self-consciousness. There is a growth inthe ability to reflect and think. Consequently, the individual bears some responsibilityfor the self-fashioning of the later stages.
  31. 31. Piaget’s Theory of Cognitive Development:From Magical Thinking to Logical Thinking Jean Piaget (1896–1980), often recognized as theforemost child psychologist of the twentiethcentury, made the growth of the child’s ability to thinkhis particular domain of investigation. Piaget, working primarily at Geneva University inSwitzerland, began his investigations into theworkings of the child’s mind because of an interest inepistemology. Epistemology, a branch of philosophy, is the studyof knowing.
  32. 32. Stages of cognitive development According to Piaget, there are four stages ofcognitive development:(1) the sensorimotor stage,(2) the preoperational stage,(3) the concrete operations stage,(4) the formal operations stage.
  33. 33. Stages of cognitive development1. The sensorimotor stage (birth to two years old). During this stage the infant has consciousness, butnot self-consciousness. He or she is, of course, aware of the environment.There are reflexes. A stimulus induces apatterned, predictable motor response. This provides aclue to the term sensorimotor and why Piaget chose it. The infant senses the world and, without reflection oranalysis, acts in response to his or her impressions.
  34. 34. Stages of cognitive development For example, one-year-old James is shown his reflection ina mirror. He is curious, of course, and reaches out to touchthe reflection. But he does not seem to know that he isseeing himself. There appears to be no sense of recognition. A postagestamp is lightly stuck to his forehead. He touches it in themirror, but doesn’t peel it off of his forehead. Tested again, when he is a little over two years old, Jamesimmediately recognizes that the stamp is on his ownforehead, and, using the mirror, peels it off. He hasdeveloped self-consciousness, a characteristic not ofinfancy, but of the next stage.
  35. 35. Stages of cognitive development2. The preoperational stage from toddlerhood to thepreschool age (two to seven years old). during this stage the child has not yet grasped theconcept of cause and effect. Instead, the child tendsto think in magical terms. Magical thinking ischaracterized by an absence of the recognition of theimportance of the laws of nature. Four-year-old Daniel sees no problem when amagician instructs a carpet to fly.
  36. 36. Stages of cognitive development Two additional characteristics of the preoperationalstage are anthropomorphic thinking and egocentrism. Anthropomorphic thinking ( ) is characterizedby a tendency to explain natural events in terms ofhuman behavior. Consequently, leaves turn various colors in the fallbecause Jack Frost paints them. The huffing and puffing of an invisible giant is thecause of a windy day.
  37. 37.  Egocentrism is a tendency to perceive oneself asexisting at the center of the universe. Everythingrevolves around the self. Consequently, five-year-old Danielle, when riding in acar at night with her parents, asks, “Why is the Moonfollowing us?” Two days later Danielle falls and scrapesher knee. She believes that her mother can feel thepain.
  38. 38. 3. The concrete operations stage is associated withmiddle childhood (seven to twelve years old). Thechild at this stage can think in terms of cause andeffect. However, most of the thinking is “concrete,” meaningthat cognitive processes at this stage deal well withwhat can be seen or otherwise experienced, not withabstractions.
  39. 39.  For example, eight-year-old Jack can easily understandthat 3 + 7 = 10 because, if necessary, this can bedemonstrated with physical objects such as pennies orchips. On the other hand, Jack can’t grasp that x + 8 = 11 inproblem 1, and that x + 8 = 24 in problem 2. If Jack istold that x is a variable, and that it can have more thanone numerical value in different problems, he will havea hard time appreciating this fact. In brief, Jack can understand arithmetic, but hecan’t understand algebra.
  40. 40.  During the stage of concrete operations, children areusually interested in how clocks work, howmeasurements are made, and why this causes that tohappen. They often like to assemble ( ) things. A game suchas Monopoly, with its play money, property deeds, andtokens, is attractive.
  41. 41. 4. The formal operations stage is associated withadolescence and adulthood. (Adolescence begins at twelve or thirteen years old).The formal operations stage is characterized by theability to think in abstract terms. The adolescent and adult can understand algebra.Subjects such as philosophy, with its variousviewpoints on life, become accessible.
  42. 42.  Not only thinking, but thinking about thinking ispossible. This is called metathought. Formal operational thought makes it possible to useboth inductive ( - )anddeductive logic ( - ). The adult can reflect, analyze, and rethink ideas andviewpoints. This kind of thought opens up avenues ofmental flexibility not available to children.
  43. 43.  Inductive reasoning is characterized by makingobservations and gathering information until a generalconclusion is reached. It is the basic method ofscience.
  44. 44.  Deductive reasoning is reasoning in which aconclusion follows from a premise. The underlying structure of deductive reasoning is if-then. Such reasoning allows for predictions, and it isoften the next step taken after inductive reasoning isemployed.

  46. 46. Freud’s Theory of Psychosexual Development:From the Oral to the Genital Stage According to Freud, there are five stages inpsychosexual development. Psychosexual development refers to the developmentof a sexual identity, attitudes toward sexualbehavior, and emotional reactions to sexualstimuli. Sexual development, in Freud’s view, is much morethan biological. They are psychological in nature. That is why Freud used the term psychosexual insteadof simply sexual.
  47. 47. Stages of psychosexual developmentThe five stages of psychosexual development are:(1) oral,(2) anal,(3) phallic(4) latency(5) genital.
  48. 48.  Libido is thought of as psychosexual energy, andFreud hypothesized that it is invested in differentzones of the body during the various stages ofpsychosexual development. These zones, or areas, of the body are called theerogenous zones, and they are associated with sexualpleasure. The principal erogenous zones are the oral, anal, andgenital areas.
  49. 49. The oral stage lasts for about two years (infancy). During this stage the infant obtains a substantialamount of pleasure from sucking, biting, chewing, andso forth.The anal stage lasts for about one or two years (thestage of the toddler, 3-4 years). During the anal stage the toddler obtains a substantialamount of pleasure from, at times, withholding fecalmatter and, at other times, expelling it. This stage coincides with the time at which childrenare toilet trained.
  50. 50. The phallic stage lasts for about three years (the stageof the preschooler, 3-4 to 6-7 years). During the phallic stage the preschooler, according toFreud, obtains a substantial amount of pleasure fromself-stimulation of the phallus. The phallus in the male is the penis. In the female it isthe clitoris. The phallic stage ends at about the age of six.
  51. 51.  Freud suggested that the child has a certain amount ofdawning sexual desire and tends to make the parentof the opposite sex the focus of this desire. However, due to moral development, guilt sets in andthe libido goes into hiding. It is repressed to an unconscious level.
  52. 52.  The emotional conflict associated with the child’sforbidden wish to seek sexual expression with a parentis called the Oedipus complex. Freud coined this term from the Greek tragedyOedipus Rex (i.e., “Oedipus, the King”) written by thedramatist Sophocles around 400 B.C. In the play, Oedipus inadvertently kills his own fatherand unknowingly marries his own mother.
  53. 53.  Writing in German in Austria, Freud used the termOedipus complex to refer to either males or females. Later authors, writing in the United States, sometimesuse the term Oedipus complex to refer to males andElectra complex to refer to females. (Electra is also aGreek play. Written by the dramatist Euripides, alsoaround 400 B.C., it bears some resemblance toOedipus Rex.)
  54. 54.  Psychosexual infantilism — Despite mother beingthe parent who primarily gratifies the child’sdesires, the child begins forming a discrete sexualidentity — “boy”, “girl” — that alters the dynamics ofthe parent and child relationship; the parents becomeobjects of infantile libidinal energy. The boy directs hislibido (sexual desire) upon his mother, and directsjealousy and emotional rivalry against his father —because it is he who sleeps with his mother.
  55. 55.  Moreover, to facilitate union with mother, the boy’s idwants to kill father (as did Oedipus), but thepragmatic ego, based upon the reality principle, knowsthat the father is the stronger of the two malescompeting to possess the one female. Nonetheless, the boy remains ambivalent about hisfather’s place in the family, which is manifested as fearof castration by the physically greater father; the fear isan irrational, subconscious manifestation of theinfantile Id.
  56. 56.  Psycho-logic defense — In both sexes, defensemechanisms provide transitory resolutions of theconflict between the drives of the Id and the drives ofthe Ego. The first defense mechanism is repression, theblocking of memories, emotional impulses, and ideasfrom the conscious mind; yet its action does notresolve the Id–Ego conflict.
  57. 57.  The second defense mechanism isidentification, by which the child incorporates, to hisor her ego, the personality characteristics of the same-sex parent; in so adapting, the boy diminishes hiscastration anxiety, because his likeness to fatherprotects him from father’s wrath in their maternalrivalry. The girl identify with mother, who understandsthat, in being females, neither of them possesses apenis, and thus are not antagonists.
  58. 58.  Dénouement — Unresolved psychosexualcompetition for the opposite-sex parent might producea phallic-stage fixation leading a girl to become awoman who continually strives to dominate men (viz.penis envy), either as an unusually seductive woman(high self-esteem) or as an unusually submissivewoman (low self-esteem).
  59. 59.  Unresolved son–father competition for the psycho-sexual possession mother might result in a phallicstage fixation conducive to a boy becoming anaggressive, over-ambitious, vain man. Therefore, the satisfactory parental handling andresolution of the Oedipus complex are most importantin developing the male infantile super ego, because, byidentifying with a parent, the boy internalizesMorality, thereby, he chooses to comply with societalrules, rather than reflexively complying in fear ofpunishment.
  60. 60. The latency stage lasts for about six years. It begins atage six or seven and ends at age twelve or thirteen. Ineffect, it ends when puberty begins. The libido has migrated from the oral to the anal tothe phallic zone. Now libido goes underground and becomes, tosurface appearance, dormant.
  61. 61. The genital stage begins at twelve or thirteen andcontinues throughout adulthood. With puberty, biological maturation can no longer bedenied. The repression lifts and the individualbecomes intensely conscious of sexual interest. Libido makes a final shift from the phallus to a moregeneral interest in the opposite sex.
  62. 62.  In normal development, the individual transferssexual interest away from the parent and towardpotential partners who are not members of the family. Freud’s outline suggests that much can go wrong withsexual development. There can be too much excitation and arousalassociated with one of the stages. Or, conversely, there can be too muchinhibition, punishment, or emotional injuryassociated with one of the stages.
  63. 63.  Freud indicated that either too much excitation or toomuch inhibition can induce a fixation oflibido, meaning the libido is to some extent “stuck” inone particular erogenous zone. According to Freud, such fixations may play a role invarious problems and maladaptivebehaviors, includingovereating, constipation, pedophilia, exhibitionism, fetishism, and sexual dysfunctions.
  64. 64.  Freud’s theory is, as are all theories, a set ofconcepts, not a set of facts. The psychoanalyst Karen Horney, one of Freud’sadvocates, rejected the biological sexuality of theOedipus complex. Instead, Horney suggested that, for example, a malechild is often jealous of the position of power andimportance the father has with the mother. The male child has a forbidden wish to take thefather’s place, not so much as a sexual rival, but as apsychological one.
  65. 65. Questions (a) During what stage does the libido make a final shiftfrom the phallus to a more general interest in the opposite sex? (b) Freud indicated that either too much excitation or toomuch inhibition can induce a of libido in one particular zone. (c) The psychoanalyst Karen Horney rejected Freud’semphasis on the of the Oedipus complex. Answers: (a) The genital stage; (b) fixation; erogenous zone;(c) biological sexuality.
