Growth and Development in Psychology

  • Development refers to the qualitative and quantitative changes that occur alongside physical growth
  • It is a progressive series of changes as an individual moves towards maturity
  • Development encompasses physical, mental, and emotional growth
  • It manifests in the emergence of new abilities and characteristics and changes in behavior
  • Jersild, Telford, and Sawrey: “Development refers to the complex set of processes involved in the emergence of a mature functioning organism from fertilized ovum”
  • E Hurlock: “Development is not limited to growing layer. Instead, it consists of a progressive series of changes toward the goal of maturity”
  • JE Anderson: “Development is concerned with growth as well as those changes in behavior which result from environmental situations”
  • Heinz Werner: “Development consists of two processes integration and differentiation”
  1. The continuous process from conception to maturity
  2. Occurs in an orderly manner and sequence: infancy, early childhood, late childhood, adolescence, maturity
  3. Includes both qualitative and quantitative aspects that are inseparable
  4. Highly complex and influenced by factors like physical attributes, intelligence, sex
  5. Rate of development can be roughly predicted but not with full accuracy
  6. Pattern and rate of development differs between individuals due to heredity, endowments, environment
  1. Physical Development
  • The most recognizable, observable change
  • Includes gross motor skills (walking, jumping) and fine motor skills (writing, drawing)
  • Dependent on the child’s health and nutrition
  • Also called maturation
  1. Cognitive Development
  • Focuses on how children learn and process information
  • Use of senses to understand the environment
  • Registering and retrieving information from memory
  • Development of Intelligence
  1. Social and Emotional Development
  • Indicators of sound social development
  • Seeds sown in infancy
  • Enjoy peer interaction and friendship
  • Develop social skills like sharing, cooperation, patience
  • Emotional development: ability to control and manage emotions
  • Importance of emotionally mature and stable caregivers
  1. Language Development
  • Communication through writing, speaking, sign language
  • Language uses words and symbols to express thoughts, desires, feelings
  • Key medium of interpersonal communication
  1. Moral Development
  • Development of ethics, morals, conscience
  • Ability to make moral judgments
  • Requires cognitive maturity
  • Growth refers to physical changes in size, weight, height, body proportions
  • Increase in weight, muscle growth
  • Quantitative changes that can be measured
  • Herbert Sevenson: growth means getting “big and heavy”

Differences between Growth and Development

  • Used in a purely physical sense
  • Refers to increase in size, length, height, weight
  • Quantitative changes that are measurable and observable
  • One part of the overall development process
  • May or may not bring development (e.g. becoming fat but no functional improvement)
  • Stops upon attaining maturity
  • Implies overall changes in shape, form, structure
  • Results in improved functioning and behavior
  • Qualitative changes that are difficult to measure directly
  • Broader, more comprehensive term
  • Possible without observable growth (functional improvement without height/size gains)
  • Continuous, lifelong process from womb to tomb
  1. Heredity
  • Biological transmission of physical and social characteristics from parents to offspring
  • Influences height, weight, body structure, hair/eye color, intelligence, aptitudes, instincts
  1. Environment
  • Sum total of an individual’s physical and psychological surroundings from conception onwards
  • Plays critical role in growth and development
  • Can be controlled to make heredity more favorable
  1. Nutrition
  • Essential for healthy physical and mental development
  • Growth and development highly dependent on food habits and nutritional intake
  • Malnutrition adversely impacts structural and functional development
  1. Sex
  • Important factor in growth and development
  • Differences between boys and girls
  • Boys generally taller, more courageous; girls show more rapid adolescent growth
  • Differing body constitution, structural growth, and functions between sexes
  1. Early Stimulation
  • Environment encourages the development of inherited potential
  • Talking to babies, and reading to preschoolers promotes language and literacy interest
  • A stimulating environment fosters good physical and mental development; lack of stimulation limits potential
  1. Child Rearing Practices
  • Parenting style impacts child development
  • Permissive parenting linked to poor responsibility, emotional control, underachievement
  • Democratic/firm parenting fosters better personal and social adjustment

Learning is an integral part of the development process. As a child develops physically, cognitively, socially and emotionally, they are constantly learning new skills and acquiring knowledge about the world around them.

  • Cognitive Development and Learning
  • Children’s developing cognitive abilities enable increasingly complex learning
  • Infants learn through sensory exploration; preschoolers develop symbolic thought and language
  • School-age children gain logical reasoning, abstract thinking, metacognition
  • Learning is constrained by children’s developmental stage and cognitive capacities
  • Social-Emotional Development and Learning
  • Secure attachment and trusting relationships create a foundation for learning
  • Emotional regulation allows children to focus attention and behavior on learning
  • Social interaction with peers and adults presents opportunities for learning
  • Affective factors like motivation, self-concept, and attitudes shape learning engagement
  • Physical Development and Learning
  • Motor development expands children’s ability to explore and interact with learning environments
  • Development of gross and fine motor skills enables participation in classroom activities (e.g. sitting still, writing, using manipulatives)
  • Perceptual development allows for increasingly refined information gathering and processing
  • Language Development and Learning
  • Language acquisition is crucial for understanding instructional content, communicating knowledge, engaging in discussions
  • Oral language skills relate to code-related skills in reading development
  • Writing development allows children to express their learning in new ways

It is clear that various developmental domains – physical, cognitive, social-emotional and language – are deeply intertwined with learning. Children’s maturation in these areas directly impacts their ability to gain knowledge and skills in both informal and formal educational contexts.

At the same time, learning experiences also spur development. Introducing new concepts, posing challenges, and encouraging skill practice can stimulate cognitive growth. Collaborative learning activities foster social competencies. Engaging in arts, music and physical education promotes motor coordination and expressive abilities.
