0-2 years
Learns about the world largely through motor abilities
How long does the preoperational stage last and how is it characterized?
2–7 years of life
Can mentally represent the past, but experiences issues with animism and egocentrism; routinely fails at conservation tasks
How long does the concrete operational stage last and how is it characterized?
7–11 years of life
Reasons well about concrete events and routinely passes conservation tasks; still experiences difficulty thinking and reasoning abstractly
When does the formal operational stage occur?
12+ years
Able to think and reason about hypothetical situations and/or abstract problems
What are attachment styles?
How children understand their relationships with important others such as parents
Name the 4 attachment styles.
Secure, insecure-avoidant, insecure-resistant, and disorganized
Who investigated the development of morality?
Kohlberg
What are the 3 stages of development related to moral reasoning?
Pre-conventional, conventional, and post-conventional
Which dilemma can help differentiate the 3 stages of development related to moral reasoning?
The Heinz dilemma
Which capabilities of the brain are shaped during adolescence?
Executive functioning capabilities
Why does risk taking often occurs in adolescence?
The prefrontal cortex not being fully mature yet
What is affected by the ability of disengaging from egocentric tendencies during adolescence?
Identity development
What is identity formation related to?
The amount of exploration a person has done and the amount of commitment given to an individual identity
How is adulthood characterized?
Fully developed frontal lobes and mental faculties
What is an extreme of declining cognitive faculties as we age?
Dementia
What is an important factor in the likelihood of dementia?
Neuroplasticity
What are ways to guard against dementia and protect one’s cognitive reserve?
Keeping active and experiencing lots of different things throughout life
What are social clocks?
Cultural understandings of what is “supposed to happen” at various points in our lives
What are the 4 adult attachment styles?
Secure, anxious-preoccupied, dismissive-avoidant, and fearful-avoidant attachments
What do adult attachment styles affect?
Intimate relationships and marriages
What is a major decision people make as they become adults and can significantly affect how a person sees him or herself as well as their psychological health?
Parenthood
What are considerable stressors that can force us to re-evaluate our lives as we approach the end of life?
Retirement and the death of loved ones
Who took a lifespan-oriented approach to development?
Erik Erikson
How many crises that people must face as they develop and mature did Erik Erikson describe?
8
Research in developmental psychology looking at the time course of development is either ____ or _____.
Longitudinal or cross-sectional
What does research on pre-verbal infants tend to focus on?
How reflexive and involuntary behaviors are shown in different situations
Name 3 examples of reflexive and involuntary behaviors.
Measuring the rate an infant sucks on a pacifier
Responses to novelty
Measuring looking time
What can be used to examine development as children get older?
Voluntary behaviors
What is a way of measuring memory?
Eliciting imitation
Explain the ethical problem for developmental researchers related to when a child should participate in research?
Children can give assent but not consent.
Name 2 challenges associated with developmental research.
Parents must be convinced to participate with their children.
Representative samples can be difficult to find.
What is development?
Growth and change over time, including changes that are progressive (e.g., learning to walk or talk) and regressive (e.g., declines in cognitive functioning with age)
True or False? Whether sleep habits are associated with academic achievement in university students would be studied by a developmental psychologist.
True
True or False? Whether changes in cognitive functioning are observed from adulthood into old age would be studied by a developmental psychologist.
False
True or False? How language develops over the first two years of life is social development.
False, how language develops over the first two years of life is COGNITIVE development.
As the ball of cells divides during the period of the zygote, it hollows out in the center. What is this hollow ball of cells called?
Blastocyst
What is an ectopic pregnancy?
A pregnancy that is the result of the fertilized egg implanting into the fallopian tube instead of the uterine wall
What is an ectopic pregnancy?
A pregnancy that results from the implantation of the blastocyst/fertilized egg into one of the fallopian tubes instead of the uterine wall
How is an ectopic pregnancy problematic?
The fallopian tube cannot expand to support a growing zygote or contract during childbirth.
When does the period of the zygote end?
2 weeks after conception, when the blastocyst implants in the uterine wall
True or False? Monozygotic twins are identical.
True
How are monozygotic/identical twins conceived?
The fertilized egg divides into two, resulting in two zygotes that have identical genetic information.
Therefore, identical twins are always of the same sex.
How are dizygotic/fraternal twins conceived?
Two eggs are released during the process of ovulation and are fertilized by different sperm, resulting in two zygotes with unique genetic makeups. As a result, fraternal twins may be of different sexes—they share no more genetic similarity to one another than do full siblings born years apart.
True or False? It is possible for a woman to be pregnant with dizygotic or fraternal twins that were conceived by sperm from two different men.
True
True or False? Dizygotic or fraternal twins are more alike genetically than two siblings who were born years apart.
False
How is development directed within the body?
Cephalocaudal (from the head to the tail)
Proximodistal (from the internal organs outward towards the extremities)
True or False? Environment toxins are teratogens.
True
True or False? Maternal mental illness is a teratogen.
False
Why is it unethical to study the effects of teratogens directly on pregnant women?
It might negatively impact their developing infant.
During which period do teratogens exert their most negative effects and why?
During the period of the embryo because it is during then that most major bodily structures are being formed
True or False? Teratogens cannot cause any negative developmental effects before a woman knows she is pregnant.
False
True or False? The dose and timing of alcohol use have been definitively linked to infant and child outcomes.
False, the dose and timing of alcohol use have not yet been definitively linked to infant and child outcomes.
Name 3 effects that alcohol can have on the developing infant.
Damage to internal organs
Altered physical characteristics
Cognitive impairments
What is another term for alcohol effects on infant development?
Sleeper effect
