Chapter 1- Lifespan Perspective

Life expectancy

Average number of years that a person is born in a particular year can expect to live.

Development

the pattern of movement or change that begins at conception and continues through the human life span. Most development involves growth, although it also includes declines brought on by aging and dying.

Lifespan perspective is...

the perspective that development is lifelong, multidimensional, multidirectional, plastic, multidisciplinary, and contextual; involves growth, maintenance, and regulation; and is constructed through biological, sociocultural, and individual factors workin

lifelong

growing and developing all the way to death, no age period dominates development.

multidimensional

development has biological, cognitive, and socioemotional dimensions. Even within every dimension, there are many components. For example, memory, attention

multidirectional

some dimensions expand while others increase. There are gains and losses within age, for example, when one language is acquired early in development (like English), the capacity for acquiring second and third languages decreases (Spanish, Chinese) later i

plastic

Plasticity means the capacity to change, within the brain and cognitive developments. It is possible that we possess less capacity for change, as we grow older. Cognitive skills for older people can be improved through training and developing better strat

multidisciplinary

psychologists, sociologists, anthropologists, neuroscientists, and medical researchers all share an interest in unlocking the mystery of development through a lifespan. How does your heredity and health limit your intelligence? Do intelligence and social

contextual

every development occurs within a context, or setting. Contexts include families, schools, peer groups, churches, etc. Historical, laboratories, countries, and so on influence each setting. Individuals are changing beings in a changing world.

Normative age graded influences

similar for individuals in a particular age group, these influences include biological processes such as puberty and menopause. Also processes in sociocultural and environmental such as beginning formal education around 6 YO and retirement from the workfo

Normative history-graded influences

common to people of a particular generation because of historical circumstances. Such as American baby boomers who during their youth experienced the Cuban missile crisis and John F. Kennedys assassination.

Nonnormative or highly individualized life events

unusual occurrences that have major impact on the lives of individual people, such as death of a parent, pregnancy in early adolescence, fire that destroys a home, etc.

biological processes

produce changes in an individual's physical nature. Genes are inherited from parents, the development of the brain, height and weight gain, motor skills, nutrition, hormonal changes in puberty, etc. are all biological processes that affect development.

cognitive processes

refers to changes in the individuals thought, intelligence, and language. Solving a crossword puzzle, watching colorful plans swing above the crib, putting together a two-word sentence, are all cognitive processes.

Socioemotional processes

involves change in the individual's relationships with other people, changes in emotions, and changes in personality. An infant's smile to a parents touch, a toddlers aggressive attack on a playmate, an adolescents joy at a senior prom are all roles of so

Prenatal

from conception to birth. Involves tremendous growth, and takes approximately 9 months to complete.

infancy

from birth to two years of age. Involves extreme dependence on adults. Many psychological activities, like language, social learning, sensorimotor coordination, are just beginning.

early childhood

from three to five years of age. Usually called the "preschool years." Children learn to care for themselves more, and develop school readiness skills.

middle and late childhood

from six to eleven years of age. Usually called the "elementary school years". During these years, children develop fundamental skills for reading, writing, and arithmetic, and are more exposed to the world and their culture.

adolescence

from eleven to twenty one years of age. Known as the TRANSITION between child-hood to adulthood. Begins with rapid physical changes, dramatic in height and weight, changes in the body. At this point in development, independence and identity are preeminent

early adulthood

begins in the twenties and ends in the thirties. Time of establishing personal and economic independence, advancing in a career, selecting a mate, and learning to live with that selected person, start a family, and have children.

middle adulthood

from approximately forty to sixty years of age. It's a time of expanding personal and social involvement and responsibility. Assisting the next generation in becoming mature individuals.

Late adulthood

from the sixty's and lasts until death. It's the time of life review, retirement, and adjustments in heath and social roles.

Young-Old

from 65-84 years of age

Oldest-Old

from 85 and older years of age

Chronological Age

The number of years that have elapsed since you were born.

Biological Age

A person's age in terms of their biological health. It pertains to the functioning capacity of their vital organs.

Psychological Age

Individuals adaptive capacities compared with those of others individuals of the same chronological age.

Social Age

The connectedness with others and the social roles individuals adopt.

Nature VS Nurture

The nature-nurture issue involves the extent to which development is influenced by nature and by nurture. Nature refers to an organism's biological inheritance, and Nurture is the environmental experiences.

psychoanalytic

Theories that describe development as primarily unconscious and heavily colored by emotion. Behavior is merely a surface characteristic, and the symbolic workings of the mind have to be analyzed to understand behavior. Early experiences with parents are e

cognitive

Cognitive theories emphasize conscious thoughts. Two theorists: Piaget's theory states that children go through four stages of cognitive development as they actively construct their understanding of the world. Vygotsky's theory is a sociocultural cognitiv

behavioral

Anything that can be directly observed and measured. Two theorists: Skinner developed his theory through operant conditioning and seeing how the consequences of a behavior produce changings in the probability of the behaviors occurrence. Bandura emphasize

ethological

stresses that behavior is strongly influenced by biology, is tied to evolution, and is characterized by critical or sensitive periods. Two theorists: Lorenz-helped bring ethology to prominence. Did the "goose" experiment. Bowlby- illustrated an important

ecological

emphasizes on environmental factors. One theorist: Bronfenbenner: created the environmental systems theory that focuses on the five environmental systems: microsystem, mesosystem, exosystem, macrosystem, and chronosystem.

Theories of development

Theories are ideas that help explain and predict things.

Observation

Naturalistic and Laboratory

Naturalistic

Observing in a natural setting, the real world settings that surround whatever you are observing.

Laboratory

a controlled setting, where most "real world" factors are removed

Survey and Interview

questionnaires, standard questions, exact same questions to all different people

Standardized Testing

Uniform procedures for administration and scoring. Allow a persons performance to be compared with the performance of other individuals.

Case Studies

Having an in-depth look at only ONE person or one single individual

Physiological measures

Performing blood samples, MRI's, mapping out genes, etc.

3 types of research design

Descriptive, Correlation, and Experimental

Descriptive

study designed to observe and record behavior. PROVES NOTHING

Correlation

study in which the goal is to describe the strength of the relationship between two or more events or characteristics. Helps PREDICT behavior, correlation does not equal causation. EX: smoking?lung cancer
� Correlation Coefficient- numerical measure to de

Experimental

demonstrates cause and effect
� Independent variable- what you're going to manipulate
� Dependent variable- what you're going to measure

Informed consent

must know any risks that are involved. Participants can withdrawal at any given time.

Confidentiality

keeping all information/data completely confidential and anonymous.

debriefing

participants must be informed of the study's purpose and the methods being used.

Deception

ensures that deception doesn't harm participants, and debrief soon after the study is completed.

Minimizing Bias

Gender, cultural, and ethnicity: Studies of life span are most useful when they are conducted without bias or prejudice toward ant particular group of people. Of special concern is bias based on gender and bias based on culture or ethnicity.
