Game
Piaget’s 3 Stages of Moral Development are
Premoral Stage
Heteronomous Stage
Autonomous Stage
The following criticisms are attached to which theory:
1. Underestimates the cognitive abilities and moral understanding of young children
2. Erroneously contends that moral development stops in late childhood or early adolescence
Piaget’s Theory of Moral Development
This stage lasts from Birth to age 5 or 6. During this stage children have very limited understanding of rules and moral behavior
Piaget’s Premoral Stage (1st)
This stage begins at about 5 or 6. During this stage children believe rules are made by authorities and cannot be changed. When judging behaviors that have negative consequences, they based their judgments primarily on the consequences of the behavior
Piaget’s Heteronomous Stage (2nd)
During this stage, when judging behaviors that have negative consequences, they based their judgments primarily on the consequences of the behavior
Piaget’s Heteronomous Stage (2nd)
This stage begins when children are about 10 or 11. Children in this stage believe rules are determined by agreement between people and can be changed.
Piaget’s Autonomous Stage (3rd)
During this stage when judging behaviors that have negative consequences, they based their judgments primarily on the actor’s intentions
Piaget’s Autonomous Stage (3rd)
Who studied moral reasoning by presenting subjects with moral dilemmas and asking them to judge each dilemma and explain their reasoning
Kohlberg
__________ is one of the best known dilemma’s which asked subjects to decide if it’s better for a husband to steal a drug to save his wife or obey the law and risk his wife’s life
Heinz Dilemma (Kohlberg)
Who believed that stages of moral reasoning are universal, always occur in the same order and are related to the person’s level of cognitive development and social perspective taking
Kohlberg
Kohlberg proposed that the ability to predict a person’s behavior from their stage of moral development is strongest when?
At higher stages of development
What are the 3 Levels of Kohlberg’s Morality
Level 1: Preconventional Morality
Level 2: Conventional Morality
Level 3: Postconventional Morality
Punishment and Obedience (acceptability of a bx depends on whether or not the bx leads to punishment) and Instrumental Hedonism (the acceptability of a bx depends on whether or not it leads to rewards or satisfies the person’s needs) are the 2 stages of which of Kohlberg’s Levels of Morality
Level 1: Preconventional Morality
Good boy/good girl ( acceptability of a bx depends on whether or not it’s liked by others) and Law and Order orientation (acceptability of a bx depends on whether it violates laws and rules established by legitimate authorities) are the two stages of which of Kohlberg’s Levels of Morality
Level 2: Conventional Morality
The morality of contract, individual rights, and democratically accepted laws (acceptability of bx is whether or not it’s consistent with democratically chosen laws) and The morality of individual principles of conscience (acceptability of bx is whether or not it’s consistent with broad, universally applicable general principles; justice and fairness) are the two stages of which of Kohlberg’s Levels of Morality
Level 3: Postconventional Morality
The following criticisms are attached to what theory:
Underestimates the moral reasoning of young children
Theory is too rigid and linear and doesn’t take into account that children’s moral judgments vary as a result of context and motivation
Only had male subjects in research (androcentric) and culturally biased, more characteristic of Western culture
Kohlberg’s Theory of Moral Reasoning
What are the 5 environmental systems in Bronfenbrenner’s Ecological Model
- Microsystem
- Mesosystem
3.Exosystem - Macrosystem
- Chronosystem
This is the child’s immediate environment and includes the child’s relationships with parents, siblings, others at home, friends, school, church
Microsystem
Interactions between elements of the child’s microsystem- influences of family relationships on child’s relationships with peers, teachers, and vice versa
Mesosystem
Consists of elements in the environment that affect the child’s immediate environment and include parent’s places of work, extended family, community health services
Exosystem
Comprised of social and cultural environments such as cultural practices, economic conditions, and political ideologies
Macrosystem
Consists of environmental events that occur over a person’s lifespan and impact the person’s development and circumstances. Includes parental divorce, job loss, birth of sibling, natural disasters.
Chronosystem
This type of inheritance occurs when a characteristic is influenced by a single pair of genes (two recessive genes or one recessive and one dominant gene).
Single gene pair inheritance
This type of inheritance occurs when a characteristic is influenced by a gene on one of the sex chromosomes, most often the X chromosome
Sex linked inheritance
This inheritance occurs when a characteristic is influenced by multiple genes. Most characteristics (height, weight, hair color, intelligence, susceptibility to cancer) fall in this category
Polygenic inheritance
New born baby’s brain is about ___% of it’s adult weight at birth & grows to about ___% by 2 years old
25% ; 80%
What is synaptogenesis?
Creation of new synapses (peaks around 2-3 years old)
What is synaptic pruning?
The loss of synapses (continues through adolescence)
What is the least developed part of the brain a birth?
Cerebral Cortex
When does the prefrontal cortex reach maturity?
early to mid 20s
At what age does brain weight and volume begin to gradually decrease? At what age does this process accelerate?
around 30 years old ; around age 60
The decrease in size of the brain is greatest for what two areas?
frontal lobe (especially prefrontal cortex) and parietal lobe
What is the least developed sense at birth?
Vision
By what age is an infant’s visual acuity similar to normal adults?
7-8 months
By what age do infants prefer to look at the face of their mother or other caregivers rather than strangers
1-2 months
What is the order that infants develop depth perception
- Kinetic (motion) cues
- Binocular (stereoscopic) cues- integration of images from both eyes
3.Pictorial (static-monocular cues)- can be perceived by only one eye which shows depth, size, texture, shadows
What 2 senses are the first to show age related decline
Vision and hearing;
What starts to happen to vision around age 40
Around 40 many adults begin to experience presbyopia- hardening of the lens of the eye- hard to focus on nearby objects. Later in life, slower dark adaptation, increased sensitivity to glare, reduced ability to discriminate between colors, decreased depth perception
What starts to happen to hearing around age 40
hearing starts to decline, decreased sensitivity to high frequency sounds (presbycusis) which makes it hard to understand women & young children’s voices, non human sounds (like microwave, dryer). Evidence that severity of age related hearing loss is related to risk of Alzheimer’s and other neurocognitive disorders
What is the first sense to develop in utero?
Touch
Early exposure to pain heightens later responsivity to pain for full term or pre-term infants?
Full term
Sudden Infant Death Syndrome (SIDS) is increased by what demographic factors

Growth spurt usually reaches it’s peak after about how long
2 years
Early onset puberty is associated with positive consequences for who?
Boys ; increased self esteem, social maturity, greater popularity, and better athletic skills
But also linked to higher alcohol use, precocious sexual bx, and antisocial bx
Lower levels of self esteem and popularity, poorer academic achievement, higher risk of precocious sexual bx, higher substance use, depression, anxiety and disruptive bx disorders is related to early onset puberty for who?
Girls

Alcohol
What are some of the potential risk factors that lead to adolescent substance use?
stressful life events, parental substance abuse, weak parent-child relationship, affiliation with deviant/substance involved peers, mental health problems (Depression and untreated ADHD), favorable attitudes towards drug use, poor social skills, and academic failuresW
What are some of the protective factors for adolescent substance use?
Parental disapproval of substance use, supportive parenting, age-appropriate parental monitoring of social bx, academic success, involvement in extracurriculars, positive peer influences, good self-control, and religiosity.
Religiosity, self-control, and parental support are buffers which means they reduce the adverse effects of stressful life events on substance use

What are the 3 stages of Prenatal development?
Germinal (conception to the end of the 2nd week when the fertilized egg implants in the uterine wall)

At what stage are teratogens, chemicals, or drugs most impactful
During embryonic period, most likely that teratogens during this period will cause major defects.
During germinal period, exposure to teratogens is likely to have either all of none effect- if exposed, implantation will not occur. During fetal period exposure to teratogens is most likely to cause minor defects and abnormalities, however, the central nervous system is highly susceptible to major damage from teratogens during embryonic and fetal periods.
