Characteristics of the Lifespan Perspective

lifelong, multidimensional, multidirectional, plastic, multidisciplinary, contextual

Life long development

no one age period dominates in development.

Multidimensional Development

Development consists of cognitive (mental), biological (physical changes), and socioemotional (intra/inter personal)dimensions

multidirectional development

Has the Critical Period and the Sensitive Period

Critical period of development

an optimal period early in the life when exposure to certain stimuli or experiences produces normal development

Sensitive period of development

This is the period when experience makes permanent alterations. This is at a young age

Plastic Development

Involves the capacity to change development throughout the lifespan

Multidisciplinary development

Psychologists, sociologists, anthropologists, neuroscientists, and medical researchers all want to research development past the lifespan

development involves growth, maintenance, and regulation of loss

Involves conflicts and competition among three goals of human development

Development is a co-construction of biology, culture, and the individual

development comes from biological, cultural, and environmental factors which influence each other

Development is contextual

All development occurs within a context e.g. families, schools, peer groups, churches, etc.

normative age-graded influences

influences that are similar for individuals in a particular age group

normative history-graded influences

influences that are common to people of a particular generation because of historical circumstances

non-normative life events

Unusual occurrences that have a major impact on a person's life. The occurrence, pattern, and sequence of these events are not applicable to many individuals.

chronicle age

number of years since birth

biological age

A person's age in terms of biological health.

psychological age

an individual's adaptive capacities compared with those of other individuals of the same chronological age

social age

connectedness with others and the social roles individuals adopt

median age

Dr. Brad Meisner's Research

focuses on the interaction of biological, phychological, and social dimensions of aging. Including adult development and older adulthood

Nature vs. Nurture

The debate about the extent to which development is influenced by nature and by nurture.

continuity-discontinuity

the debate about the extent to which development involves gradual, cumulative change (continuity) or distinct stages (discontinuity)

stability and change

Do our early personality traits persist through life, or do we become a different person as we age?

Theory

an explanation using an integrated set of principles that organizes observations and predicts behaviors or events

Hypothesis

A testable prediction, often implied by a theory

psychoanalytic theory

Theories holding that development depends primarily on the unconscious mind and is heavily couched in emotion, that behaviour is merely a surface characteristic, that it is important to analyze the symbolic meanings of behaviour, and that early experiences are important in development.

Freud's Theory

basic principles include the unconscious mind, early childhood experiences, and influence of sexual drives, includes id/ego/superego and psychosexual stages

Erikson's Psychosocial Theory

Primary motivation for behaviour is based on social outcomes. The stage theory of psychosocial development, lifespan consists of eight dilemmas that must be solved correctly in order to solve the next dilemma

Piaget's stages of cognitive development

1. sensorimotor

2. preoperational

3. concrete operational

4. formal operational

sensoriomotor stage

in Piaget's theory, the stage (from birth to about 2 years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities

preoperational stage

in Piaget's theory, the stage (from about 2 to 6 or 7 years of age) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic

concrete operational stage

in Piaget's theory, the stage of cognitive development (from about 6 or 7 to 11 years of age) during which children gain the mental operations that enable them to think logically about concrete events

formal operational stage

in Piaget's theory, the stage of cognitive development (normally beginning about age 11) during which people begin to think logically about abstract concepts

Vygotsky's Sociocultural Theory

the approach that emphasizes how cognitive development proceeds as a result of social interactions between members of a culture where knowledge is situated and collaborative

Pavlov's Classical Conditioning

a neutral stimulus acquires the ability to produce a response originally produced by another stimulus

Skinner's Classical Conditioning

consequences of behaviour change likelihood of the behaviour's future occurrence where rewards increase the likelihood of reoccurrence (punishments decrease this chance)

Bandura's Social Cognitive Theory

Holds that behavior, environment, and person/cognitive factors are the key factors in development

Ethology

Focuses on responses to environment, physiological makeup, communication, & evolutionary aspects

Charles Darwin

one of the first ethologists and focused on evolution and natural selection

Konrad Lorenz

researcher who focused on critical attachment periods in baby birds, a concept he called imprinting

John Bowlby

argued that infants innately channel signals to primary caregivers to form attachment

Carl Rogers

Developed "client-centered" therapy

Congruence and Incongruity

the relationship between the ideal and perceived self

Abraham Maslaw

developed the idea that there is a hierarchy of human needs

Maslow's Hierarchy of Needs

(level 1) Physiological Needs, (level 2) Safety and Security, (level 3) Relationships, Love and Affection, (level 4) Self Esteem, (level 5) Self Actualization

the bio-ecological approach

Urie Brofenbrenner and his evaluation of the bio-ecological approach

Brofenbrenner's Ecological Systems Theory

views the child as developing within a complex system of relationships affected by multiple levels of the surrounding environment

Brofenbrenners Levels

The individual: gender, age, health, SES
Microsystem: family, school, groups, neighbourhood
Mesosystem: relationship between the microsystem factors
Exosystem: other social settings
Macrosystem: attitudes/ideologies of the culture
Chronosystem: patterning of events and transitions over one's life

dynamic systems approach

a view of human development as an ongoing, ever-changing interaction between the physical, cognitive, and psychosocial influences. Challenges can encourage development

evolutionary psychology

the study of the evolution of behavior and the mind, using principles of natural selection. Nature/Nurture

neuroscience and neuroplasticity

focuses on the brain, nervous system, and spinal cord

positive psychology

the scientific study of optimal human functioning; aims to discover and promote strengths and virtues that enable individuals and communities to thrive

the eclectic approach

an approach to psychotherapy that uses techniques from various forms of therapy. Gives a more comprehensive explanation

natural selection

A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.

linkage analysis

goal is to discover the location of a gene in relation to a known marker gene. Often used in the search for disease related genes

sex-linked genes

a gene that is carried on the X or Y chromosome. X-linked genes are more severe in males as they only have one X chromosome.

Colour Blindness, Hemophilia

Two conditions associated with sex linked patterns of inheritance

polygenetic inheritance

personal traits or physical properties that are influenced by many genes working in combination - eye color, hair color, height, and skin color

Down Syndrome

a condition of intellectual disability and associated physical disorders caused by an extra copy of chromosome 21.

Fragile X Syndrome

the inability to concieve naturally after 12 months of unprotected (heterosexual) sex

stem cells

unspecialized cells that retain the ability to become a wide variety of specialized cells

behaviour genetics

seeks to discover the influence of hereditary and environment on individual differences in human traits and development

epigenetic view

emphasizes that development is the result of an ongoing, bidirectional interchange between heredity and environment

Dr. Bombay's Research

Is studying the intergenerational transitions of trauma and the role of resilience in Canadas indigenous people. Traumatic experiences can negatively affect a child's development interfering with the expression of the individuals DNA

germinal period

The first two weeks of prenatal development after conception, characterized by rapid cell division and the beginning of cell differentiation.

embryonic period

the period from 2 to 8 weeks after fertilization, during which the major organs and structures of the organism develop
