5. Understand the different stages of development that an individual will pass through.
I. THE BEGINNING OF LIFE
DEVELOPMENT:
Is a process that continues from conception to death.
It is a process of a life-span from a single cell through late adulthood, and is influenced by the interaction of heredity and environment
THREE MAJOR PATHS OF HUMAN DEVELOPMENT:
Physical development:
Changes in bodily appearance and structure, with changes in bodily activities like motor skills.
Psychosocial development
Includes changes in social and emotional aspects of personality.
Cognitive development
Changes in the thought processes that could affect language, learning abilities, and memory.
Qualitative changes
Refer to a progressive series of change leading to improvement like those changes in kind that distinguish an infant who have underdeveloped motor skill from a baby who can walk already.
Quantitative changes Refer to the measurable changes in an individual like changes in height, body proportion, and the like. Quantitative changes referred to as growth though growth may be used interchangeably with development.
Two factors of development:
Nature: Is responsible for cognitive aspects such as mental capacities, innate traits and other materials that contribute to development as passed upon generations through heredity.
Nurture: Is associated with environment that provides the stimuli for nourishment and proper development of certain organism.
