Life Span Development

Erik Erikson’s theory outlines eight distinct stages of psychosocial development, spanning from infancy to old age. Each stage presents a specific crisis or challenge:

• Infancy: Trust vs. Mistrust
• Adolescence: Identity vs. Role Confusion

Successful resolution of these crises leads to psychological growth and a stronger sense of self, while failure can result in difficulty navigating future stages.

Harry Harlow’s groundbreaking experiments revealed that baby monkeys formed stronger attachments to soft, cloth-covered surrogate mothers than to wire mothers that provided food.

This demonstrated that contact comfort, or tactile sensation, was more critical for emotional bonding than mere nourishment.

• Key Insight: Physical warmth and comfort play a vital role in fostering a sense of security and attachment in infants.

Permissive parenting is characterized by a lack of rules, boundaries, and expectations. Parents who adopt this style tend to be nurturing and accepting but fail to enforce consistent discipline.

• Impact: Children may struggle with self-regulation and authority.
• Goal: While permissive parents often aim to foster independence, the absence of structure can lead to behavioral and emotional challenges.

According to Kohlberg’s stages of moral development, the preconventional level is the first stage of moral reasoning. At this stage:

• A child’s decisions are primarily driven by the consequences of their actions, such as avoiding punishment or seeking rewards.
• This stage reflects a self-centered approach to morality, where external outcomes dictate behavior.

Below are key psychological theories and their contributors:

• Psychosexual Perspectives (A): Sigmund Freud introduced this theory, emphasizing stages of personality development driven by unconscious desires.
• Psychosocial Theory (B): Erik Erikson outlined eight stages of development, each focusing on a social conflict or task.
• Moral Development Theory (C): Lawrence Kohlberg proposed this framework to describe the progression of ethical reasoning.
• Cognitive Dissonance Theory (D): Leon Festinger developed this theory, highlighting how individuals strive to reduce the discomfort caused by conflicting beliefs or attitudes.

Erikson’s psychosocial development stages describe tasks associated with each life stage:

• Autonomy vs. Shame and Doubt (A): This occurs during the toddler years (II), focusing on independence and self-control.
• Initiative vs. Guilt (B): Present in early childhood (III), it involves exploring and initiating activities while learning to balance ambition with guilt.
• Generativity vs. Stagnation (C): During middle adulthood (IV), individuals strive to contribute to society through work, parenting, or mentorship.
• Ego Integrity vs. Despair (D): Occurs in late adulthood (I), where individuals reflect on their life and seek a sense of fulfillment or risk despair.
