Comprehensive Notes on Cognitive, Moral, and Psychosexual Development Theories

Piaget’s Theory of Cognitive Development

  • Piaget’s theory is widely used in education programs to prepare teachers to instruct students in developmentally appropriate ways.
  • Definition of Cognitive Development: Refers to the growth and change in intellectual abilities such as thinking, reasoning, understanding, problem-solving, and the acquisition of knowledge. It's how children (and people throughout their lives) come to understand the world around them.

Stages of Cognitive Development

  • Sensorimotor Stage (00 to 22 years old):
    • Children learn about the world primarily through their senses and motor actions.
    • They "think" by touching, grasping, looking, listening, and manipulating objects.
    • Object Permanence: A crucial development in this stage where children gain the understanding that people and objects still exist even when they’re out of view.
  • Preoperational Stage (2−72 - 7 years old):
    • Symbolic Thought: Children begin to progress from concrete to abstract thinking. They begin to use symbols (words, images) to represent objects and ideas.
    • Thinking is often egocentric and lacks logical reasoning.
    • Imaginary Friends: Children in this stage often have imaginary friends.
    • Symbolic Meaning Examples: A child uses a banana as a telephone, or pretends a stick is a sword, demonstrating the ability to assign symbolic meaning to objects.
  • Concrete Operational Stage (7−117 - 11 years old):
    • Children solidify their abstract thinking.
    • They begin to understand cause and effect and the logical implications of actions.
  • Formal Operational Stage (Adolescence to Adulthood):
    • Humans learn to plan for the future, think hypothetically, and assume adult responsibilities.
    • Individuals develop the ability to think abstractly, reason hypothetically, and engage in systematic problem-solving.

Kohlberg’s Theory of Moral Development

  • Lawrence Kohlberg created a theory of human development based on moral development concepts.
  • It is a highly influential framework that describes how individuals progress in their moral reasoning through a series of stages.
  • This theory builds on Piaget's work in cognitive development.
  • Evolution of Moral Reasoning: Kohlberg proposed that reasoning evolves not based on what a person decides is right or wrong, but on how they arrive at that decision—the thought process behind it.

Levels and Stages of Moral Reasoning

  • Preconventional Level (Typically children under 99):
    • Moral reasoning is primarily driven by self-interest and the direct consequences of actions.
    • People follow rules because they’re afraid of punishment and make choices only with their best interests in mind.
  • Conventional Level (Typically adolescents and adults):
    • Moral reasoning is based on conforming to social rules, expectations, and laws to maintain order and gain approval.
    • People act to avoid society’s judgment and follow rules to maintain established systems and structures.
    • Stage: Good Interpersonal Relationships (Good Boy/Good Girl Orientation):
      • Focus: Living up to the expectations of others; being a "good" person to gain approval and maintain relationships. Intentions matter.
      • Heinz Dilemma Example: Heinz should steal the drug because that's what a good husband would do—he's saving his wife, and people will think he's a loving spouse. Alternatively, he shouldn't steal it because good people don't break the law, and his family might be ashamed of him.
    • Stage: Maintaining the Social Order (Law and Order Orientation):
      • Focus: Upholding laws, rules, and authority to maintain social order and prevent chaos. Duty and respect for authority are important.
      • Heinz Dilemma Example: Heinz should not steal the drug because stealing is against the law, and if everyone stole, society would fall apart. It is his duty to obey the law.
  • Postconventional Level:
    • Guided by a genuine concern for the welfare of others and the greater good of society.
    • Moral reasoning is based on abstract, universal ethical principles that may or may not align with societal laws.
    • Individuals operate on principles of justice and individual rights.

Freud’s Psychosexual Theory of Development

  • Ideally, children move through each phase fluidly as their sexual libidos develop.
  • Fixation: If a child gets "stuck" in any of the phases, they may develop a fixation that hinders their development.

Stages of Psychosexual Development

  • Oral Stage (Birth to 11 year):
    • Erogenous Zone: Mouth (sucking, biting, chewing, feeding).
    • Conflict/Task: Weaning from the breast or bottle.
    • Children learn to suck and swallow; primary interaction with the world is through the mouth, and pleasure is derived from oral stimulation.
    • Potential Fixations:
      • Oral-receptive personality: Overly dependent, passive, naive, easily manipulated (due to over-gratification).
      • Oral-aggressive personality: Aggressive, sarcastic, argumentative, prone to nail-biting, smoking, overeating, or excessive drinking (due to under-gratification or early weaning).
  • Anal Stage (1−31 - 3 years):
    • Erogenous Zone: Anus (bowel and bladder control).
    • Conflict/Task: Toilet training.
    • Children learn to withhold or expel feces; this is the first encounter with external demands and control, learning to delay gratification.
    • Potential Fixations:
      • Anal-retentive personality: Orderly, obsessive, stubborn, stingy, neat, meticulous (due to overly strict or early toilet training).
      • Anal-expulsive personality: Messy, disorganized, reckless, defiant, wasteful (due to overly lenient or late toilet training, or rebellion against strictness).
  • Phallic Stage (3−63 - 6 years):
    • Erogenous Zone: Genitals (curiosity about sexual differences, self-stimulation).
    • Conflict/Task: The Oedipus Complex (for boys) and Electra Complex (for girls).
    • Oedipus Complex: Boys develop sexual desires for their mother and view their father as a rival, fearing castration by the father (castration anxiety). Resolved by identifying with the father and internalizing his morals, leading to the development of the superego.
    • Electra Complex: (Jung's term, incorporated by Freud) Girls develop sexual desires for their father and experience "penis envy," feeling incomplete without a penis. They eventually identify with their mother, hoping to symbolically "gain" a penis through a child.
    • Potential Fixation: Phallic personality: Vain, narcissistic, reckless, self-assured (males), or flirtatious, promiscuous (females). Difficulties with sexual identity, authority figures, or intimate relationships.
  • Latency Stage (66 to puberty):
    • Erogenous Zone: None (sexual urges are dormant or repressed).
    • Conflict/Task: Sexual energy is sublimated into non-sexual activities like school, hobbies, and social development. Focus on social skills, intellectual pursuits, and friendships with same-sex peers.
    • Fixation: Freud believed no new fixations occurred during this stage; it's a period of relative calm.
  • Genital Stage (Puberty to adulthood):
    • Erogenous Zone: Genitals (maturation of sexual interests, desire for mature sexual relationships).
    • Conflict/Task: Developing mature sexual and romantic relationships, establishing independence, finding a life partner, and contributing to society.
    • Fixation: If previous stages were successfully navigated, the individual develops a healthy personality capable of loving and working. Fixations from earlier stages may manifest as difficulties in forming stable, adult relationships.
