Fine motor skills, such as grasping objects and picking up small items, develop during the first year of life.
Studying development is key to understanding changes over the course of development, what stimulates and constrains developments, and what problems may develop along the way
Understanding what occurs in infancy, early childhood, or adolescence can provide clues to understanding adult mental states and behaviors
Human development involves physical, cognitive, and psychosocial development throughout the lifespan
Development is a pattern of movement or change that begins at conception and continues through the human lifespan
Development involves systematic continuities and changes in the individual over the course of life
Developmental continuities refer to ways in which individuals remain stable over time or continue to reflect their past
Conception marks the onset of development, from the moment the father's sperm penetrates the mother's ovum, creating a new organism
Development is a lifelong process and does not stop at a certain age
Physical development involves growth and changes in the body and brain, motor skills, senses, and health
Cognitive development includes learning, attention, memory, language, thinking, reasoning, and creativity
Psychosocial development encompasses emotions, personality, self-esteem, and social relationships
The continuity/discontinuity issue in human development involves a debate about whether changes are quantitative and continuous or qualitative and discontinuous
The nature vs. nurture debate questions whether human development is primarily influenced by biological forces (nature) or environmental forces (nurture)
There is a reciprocal interaction between nature and nurture in shaping human development
The active/passive theme debate in developmental psychology questions whether children are active contributors to their own development or passive recipients of environmental influence
The holistic nature of development theme explores how different aspects of human development are interrelated and influence each other as the child matures
Periods of human development are divided into eight stages: prenatal development, infancy and toddlerhood, early childhood, middle childhood, adolescence, early adulthood, middle adulthood, and late adulthood
Prenatal development involves the germinal, embryonic, and fetal periods, where major structures of the body form and the mother's health is crucial
Infancy and toddlerhood are characterized by dramatic growth, brain development, and interactions with primary caregivers
Early childhood, around ages 2-6, involves gaining a sense of self, learning about the physical world, and developing social skills
Middle childhood, ages 6-11, focuses on academic skills, social relationships, and motor skill refinement
Adolescence, roughly between 12-18, is marked by puberty, cognitive changes, and socioemotional development
Adolescence is a time of cognitive change where new possibilities are considered, and abstract concepts like love, fear, and freedom are explored
Teens often have a sense of invincibility that can put them at greater risk
A major developmental task during adolescence involves establishing one's own identity
Teens typically struggle to become more independent from their parents
Adolescents strive for a sense of belonging and acceptance
New roles and responsibilities are explored during adolescence
Early adulthood, roughly ages 20-40, may be split into a category of "emerging adulthood" with profound differences between younger and older adults
Love and work are primary concerns in early adulthood
Middle adulthood spans the years between ages 40-65
Late adulthood is generally viewed as age 65 and older, with variations in health and lifestyle between different age groups
Dying and grieving are processes that may share certain stages of reactions to loss
The third stage is the phallic stage, where children become aware of sexual differences and may experience Oedipus or Electra complexes.
Baltes' Lifespan Perspective includes key principles such as development occurring across one's entire life, being multidimensional, multidirectional, plastic, influenced by contextual and socio-cultural factors, and multidisciplinary
Development occurs across the entire lifespan, from conception to death
Development is a complex interaction of biological, cognitive, and socioemotional changes
Development results in gains and losses throughout life
