Review Questions

• How do major theories in developmental psychology contribute to our understanding of human growth across the lifespan?
  • Major theories in developmental psychology, such as those proposed by Piaget and Erikson, provide frameworks for understanding how individuals evolve over time. Piaget's theory of cognitive development outlines stages through which children develop logical thinking and problem-solving skills. Erikson's psychosocial stages highlight the social challenges faced at different ages, emphasizing the importance of resolving conflicts for healthy development. Together, these theories help us grasp the complex interplay of cognitive and social factors influencing growth throughout life.
• Discuss the significance of attachment theory in understanding early child development and its implications for later relationships.
  • Attachment theory emphasizes the crucial role early emotional bonds play in a child's development. The quality of attachment formed between infants and their caregivers can significantly influence the child’s social and emotional well-being later in life. Secure attachments often lead to healthier relationships in adulthood, while insecure attachments may contribute to difficulties in forming connections. This understanding underscores the importance of nurturing environments during critical developmental periods.
• Evaluate how the life span perspective alters our view of development compared to traditional stage theories.
  • The life span perspective shifts our understanding of development from a stage-based approach to viewing growth as a continuous process occurring throughout life. Unlike traditional theories that often emphasize specific stages during childhood or adolescence, this perspective acknowledges that development can happen at any age and is influenced by an array of factors including culture, environment, and individual experiences. This holistic view encourages a more nuanced understanding of how people adapt to life changes across their entire lifespan.
