Developmental PsychologyDevelopmental Psychology

Developmental psychology –The study of how organisms change over time as the result of biological and environmental influences


How Do PsychologistsHow Do PsychologistsExplain Development?Explain Development?

Development is a process of growth and change brought about by an interaction of

heredity and the environment


The Nature-NurtureThe Nature-NurtureInteractionInteraction

Nature-nurture controversy –Long-standing dispute over relative importance of nature (heredity) and nurture (environment) in their influence on behavior and mental processes



Twin studies – Developmental investigations in which twins, especially identical twins, are compared in the search for genetic and environmental effects



Adoption studies – Studies in which the adopted child’s characteristics are compared to those of the biological family and the adoptive family

Developmental stages – Periods of life initiated by significant transitions or changes in physical or psychological functioning


Psychological Traits in Your GenesPsychological Traits in Your Genes

While psychological traits are formed by interaction of heredity and the environment, many traits have a strong genetic influence

Self-fulfilling prophecy –An expectation that becomes realized because it guides people’s behaviors

What Are theWhat Are theDevelopmental Tasks ofDevelopmental Tasks ofInfancy and Childhood?Infancy and Childhood?

Infants and children face especially important

developmental tasks in the areas of language, acquisition,

cognition, and social relationships – tasks that lay a foundation for further growth in

adolescence and adulthood


How Children Acquire LanguageHow Children Acquire Language

Innateness theory of language –Children learn language mainly by following an inborn program for acquiring vocabulary and grammar

Language acquisition device (LAD) – Structure in the brain innately programmed with some of the fundamental rules of grammar



Babbling stage

Vocabulary and grammarOne-word stage

Two-word stage

Telegraphic speech (short, simple sentences)

Morphemes (meaningful units of language that make up words)

Overregularization (e.g. using “hitted” and “feets”)



Other language skills

Social rules of conversation

Abstract words (e.g. hope, truth)


Cognitive DevelopmentCognitive Development

Cognitive development –The process by which thinking changes over time

Schemes –Mental structures orprograms that guide adeveloping child’s thoughts


Accommodation –Mental process thatrestructures existingschemes so that newinformation is better understood

Cognitive DevelopmentCognitive Development

Assimilation – Mental process that modifies new information to fit it into existingschemes

Temperament –An individual’s characteristic manner of behavior or reaction

Socialization –The lifelong process of shaping an individual’s behavior patterns, values, standards, skills, attitudes and motives to conform to those regarded as desirable in a particular society

What Changes Mark theWhat Changes Mark theTransition of Adolescence?Transition of Adolescence?

Adolescence offers new developmental challenges

growing out of physical changes, cognitive changes, and socio-emotional changes


The Transitions of AdolescenceThe Transitions of Adolescence

Adolescence – Developmental period beginning at puberty and ending at adulthood

Rites of passage – Social rituals that mark the transition between developmental stages, especially between childhood and adulthood


Puberty – Onset of sexual maturity

Around puberty, boys and girls become more aware of their physical attractiveness

Physical Maturation in AdolescencePhysical Maturation in Adolescence

Menarche – Onset of menstruation, which signals puberty in girls


Hormones rise to high levels

The frontal lobes undergo a “remodel”

This leads to sensation seeking and risk taking, and preoccupation with body image and sex

What DevelopmentalWhat DevelopmentalChallenges Do Adults Face?Challenges Do Adults Face?

Nature and nurture continue to produce changes throughout life, but in

adulthood these changes include both growth and

decline


The Developmental Challenges of The Developmental Challenges of AdulthoodAdulthood

Love and workIntimacy versus isolation

Generativity versus stagnation

Generativity –A process of making a commitment beyond oneself to family, work, society, or future generations


The Last Developmental Problems The Last Developmental Problems You Will FaceYou Will Face

Ego-identity –The ability to look back on life without regrets and to enjoy a sense of wholeness

According to Erikson, the final crisis involves ego-identity vs. despair
