Maturation
Unfolding of a biologically determined sequence of behavior patterns, including readiness to master new abilities.
Lifespan Development
Concept of development as a lifelong process of adaptation.Lifelong, function of history and context, multidimensional, multidirectional, and pliable/plastic.
Multidirectional
Development can result in both increases and decreases, at varying rates, within the same person, age period, or category of behavior.
Multidimensional
Development can affect multiple capacities or aspects of a person. Personality, intelligence, and perception can be changing at the same time.
Plasticity
Modifiability of performance. It is possible to improve functioning throughout the life span, though there are limits on how much a person can improve at any age.
History and Context
People develop within a physical and social context, which differs at different points in history. Individuals not only respond to their context but also interact with and actively influence it.
Multiple Causality
Development has multiple causes. Because no single perspective can adequately describe or explain the complexities of development, the study of lifespan development requires cooperative, multidisciplinary efforts of scholars from many fields.
Ageless Self
Perception that the self remains the same despite chronological aging and physical change.
Chronological Age
Count of how many times an inhabitant of this planet has orbited the sun.
Functional Age
Measure of how well a person can function in a physical and social environment as compared with other people of the same chronological age.
Gerontologists
Scientists who study aged people and the aging process.
Biological Age
Measure of how far a person has progressed along a potential life span; predicted by person’s physical condition.
Social Age
Depends on how closely behavior conforms to the norms, expectancies, and roles a person of a certain chronological age is expected to play in society.
Normative Age-Graded Influences
Biological and environmental influences on development that are highly similar for people in a given age group.
Normative History-Graded Influences
Biological and environmental influences on development that are common to a particular cohort.
Cohort
Group of people who share a similar experience.Ex. Growing up at same time in the same place.
Nonnormative Life Events
Unusual events that have a major impact on individual lives.
Bioecological Approach
Bronfenbrenner’s system of understanding development, which identifies five levels of environmental influences, from most intimate to broadest.Microsystem, mesosystem, exosystem, macrosystem, and chronosystem.
Microsystem
Everyday environment of home, school, work, or neighborhood.
Mesosystem
Interlocking of various microsystems - linkages between home and school, work and neighborhood.
Exosystem
Linkages between a microsystem and outside systems or institutions that affect a person indirectly. How does community’s transit system affect job opportunities?
Macrosystem
Overarching cultural patterns, such as dominant beliefs, iideologies, and economic and political systems.
Chronosystem
Adds the dimension of time: change or constancy in the person and the environment.
Ageism
Prejudice or discrimination, usually against older persons, based on age.
