Lifespan Development
PSYC211 Fall 2014
Conception and Pregnancy
DNA: Provides instructions for the cells to grow and sustain life
Chromosomes: Each molecule of DNA
46 chromosomes and 23 pairs
23rd pair is the gender chromosome--- dad's sperm decides
Genes: Units of information located on the chromosome
Gamete: Reproductive cell (egg and sperm)
Allele: Variations of a gene
Genome: The entire genetic code for a species
Genotype: One person's genetic code
Phenotype: The expression of one person's genetic code
Dominant Genes: Genes that express themselves
Recessive Genes: Genes that are hidden
X-linked genes: Genes that are recessive and are on the X chromosome therefore they impact males more than females
Newborn and Infancy
Early Childhood
Focus on exploring the world through direct interaction and the beginnings of symbolic thought
-Limited logical ability
Focus on developing autonomy, and initiative
Focus on the dichotomy between teacher centered and student centered teaching
Limbic system developing
Adult proportions; Gross and Fine Motor Skill Development
Focus on gaining rewards and avoiding punishments
Old Age
Focus on developing integrity
Brain begins to slow down; myleination thins
Body begins to slow down; stroke; osteoporosis
Middle Childhood
Focus on exploring the world through logic and rules
-Limited abstract thinking ability

Focus on developing industry

Finish the development of the pre-frontal cortex
Focus on ideals
Focus on developing intimacy and generativity
Body at it's peak; Peak fertility
Brain is finished development and is also at it's peak
Every child starts as a
or a single cell
Germinal Period:
First two weeks of pregnancy
Zygote duplicates and divides
Stem Cells
are produces which direct the production of all the other cells
Cells specialize depending on location
Week 2: Outer cells become placenta and the inner cells become the embryo; outer cells implant in the uterus lining
Embryonic Period:
Weeks 3-8
Day 14: Primitive streak appears which eventually develops into the nervous system
Week 4: head and face starts to form and the heart starts to beat
Week 4: Arms and legs form
Development occurs from head to tail with the extremities forming last... the brain needs the most time
Fetal Period:
Weeks 9-birth
Sex organs start to develop
Male fetus experiences a rush of testosterone
Body systems begin the develop
Brain increases to six times in size
22 weeks: The newborn may be able to survive on their own outside the womb
The brain begins to fold
Oxytocin is released which prepares the fetus for delivery and begins labor
Genetically identical
Share half of their genes

Lasts only one month
Senses and motor reflexes
Stage 2 (First habits) (1 month-4 months)
Can adapt their reflexes to specific stimuli

Cognitive Development
Concrete Operational Thought:
Ability to reason logically about direct experiments and perceptions
Organize things into groups based on a common characteristic they share
The understanding that things can be arrange in a logical series
-Less egocentric and more flexible
Cognitive Development
-Formal Operational Thought:
More systematic logical thinking and the ability to understand and systematically manipulate abstract concepts
-Hypothetical Reasoning:
Ability to reason about if-than statements that do not impact reality
-Deductive Reasoning:
Can move from an abstract idea to a specific conclusion
Social Learning (Vygotsky)

Children learn when adults present challenges, offer assistance, add crucial information and encourage motivation
Zone of Proximal Development (ZPD):
What the child can do with help
Temporary help from parents to reach the ZPD
Imitate the irrelevant actions of adults
Criticisms of Piaget
1) Piaget believes that development is automatic and the same for all children
Behaviorists believe that development is contingent on the environment
We know that children progress through stages at different paces
We know that some children do not progress through all the stages; Piaget does not offer an explanation for this
2) Piaget may have used overly complicated tasks to measure certain constructs such as theory of mind
Modern research shows that children in early childhood are much more sophisticated thinkers than Piaget originally thought
3) Piaget expects thinking across developmental tasks to be the same in the same stage
This has been shown false; children pick up on different concepts and apply them to different tasks with diversity
4) Piaget believes that it useless to teach children beyond their development level
Vygotsky's theory of Zone of Proximal Development
Piaget's Stages of Cognitive Development
Kay C. Wood, Harlan Smith, Daurice Grossniklaus
Department of Educational Psychology and Instructional Technology, University of Georgia

-Erikson's stages are gender specific to males. Identity development for females should result in intimacy and relationships rather than autonomy and independence.
2) Erikson used thought rather than the scientific method to create his theory.
3) Erikson's stages become vaguer and more difficult to define later in life (i.e. integrity vs. despair).
4) Are the identity crises ever fully resolved?
5) Erikson's stages are very culture dependent.

If you had limited resources to feed a population and could only ensure that a group of children received adequate nutrients during one time period in development which would you choose and why?
Stages of Social Play
Solitary Play:
A child plays alone
Onlooker Play:
A child watches others play
Parallel Play:
Children play with similar objects in similar ways but not together
Associative Play:
Children interact, sharing materials but their play is not reciprocal
Cooperative Play:
Children play together, create dramas or take turns

Rough-And-Tumble Play:
Children chase, wrestle and grab each other
May help the prefrontal cortex develop as children learn to regulate emotions, practice social skills and strength bodies

Children act out various role and plots
Explore and rehearse social roles
Learn how to persuade playmates
Practice emotional regulation
Develop self-concept
-Play is a sign of healthy development and can provide cues about how the child will develop later in life
-Adults involvement in play depends on the security of the community
-Children's play typically starts out as an individual activity then becomes a social one
Active Play
Functional play
Plays with toys in the way that they were designed to be played with

Creates something while playing (i.e. building a tower out of blocks)
Dramatic or symbolic play
Games with rules
Types of Play
Moral Development
Preconventional Moral Reasoning:
Avoid punishments and gain rewards
Stage 1:
Punishment and Obedience
Avoid punishment
Do what is in your own self-interest
Stage 2:
Look out for yourself
Take care of yourself and only yourself
Moral Development
Conventional Moral Reasoning:
Social Rules
Stage 3:
Social approval is the most important; strive for proper behavior to please others
Stage 4:
It is important to obey the laws set by society even when nobody is looking
Moral Development
Postconventional Moral Reasoning:
focus on ideals
Stage 5:
We obey societal rules because they are established by everyone they are based on mutual agreement; parties can leave at anytime; disobedience is not always immoral
Stage 6:
Universal principles determine right and wrong; establish these through individual reflection

Review: Moral Development
1. Kohlberg's first stage of moral development is _______________________. It has two stages. In stage one children are concerned with ________ ___________. In stage two children are concerned with getting ___________.
2. Kohlberg's second stage of moral development is ________________. It also has two stages. In stage three children are concerned with _________ ________. In stage four children are concerned with _______________.
3) Kohlber's third stage of moral development is ________________. It also has two stages. In stage five people are concerned with ___________ _______________. In stage six people are concerned with _______________ _________________ of right and wrong.
Quiz: Moral Development
Write what someone in each stage of Kohlberg's 6 stages would do and why.
Criticisms of Kohlberg
Is it good for society for people to strive to have their own principles of right and wrong rather than obeying the laws that society has created? Is that more ethical than obedience? What if the person is wrong?
Cultural bias: Eastern societies tend to stop in stage 3 of Kohlberg's theory; but they also show moral growth unaccounted for by Kohlberg's theory.
Gender bias: Men are more concerned with abstract hypothetical ideals while women are more concerned with interpersonal relationships.
Difficult to operationally define the stages
Is a stage still valid if the majority of the population doesn't reach it?
