developmental psychology
a branch of psychology that studies physical, cognitive, and social change throughout the life span
Zygote
the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo.
Embryo
the developing human organism about 2 week after fertilization through the second month
fetus

Fetal Alcohol syndrome
Physical and cognitive abnormalities in children caused by a pregnant woman's heavy drinking. In severe cases, signs include out of proportion head and abnormal facial features.
Habituation
decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulus. Their interest wanes and they look away sooner.
Maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience.
Jean Piaget
believed that children construct their understanding of the world while interacting with it. In his view, psychology consisted of four major stages-sensorinmotor, preoperational, concrete operational, and formal operational.
Schema
a concept or framework that organizes and interprets information.
Assimilation
interpreting our new experiences in turns of our existing schema.
Accommodation
adapting our current understandings (schema) to incorporate new information.
Sensorimotor stage
in Piaget's theory, the stage (from birth to nearly two years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities.
object permanence
the awareness that things continue to exist
stranger anxiety
the fear of strangers that infants commonly display, beginning by about 8 months of age
preoperational stage
in Piagets theory, the stage (from about 2 to 6 or 7) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic.
Theory of Mind
People's ideas about their own and other's mental states-about their feelings, perceptions, and thoughts and the behaviors these might predict.
egocentrism
in Piaget's theory, the preoperational child's difficulty taking another's point of view.
concrete operational stage
in Piaget's theory the stage of cognitive development (from about 7-11) during which children gain the mental operations that enable them to think logically about abstract concepts.
conservation
the principle (which piaget believed to be a part of concrete operational reasoning) that properties such as mass, volume, and number remain the same despite changes in the forms of objects.
Formal operational stage
In Piaget's theory, the stage of cognitive development (normally beginning at age 12) during which people begin to think logically about abstract concepts.
Lev Vygotsky
A Russian psychologist. He emphasized how a child's mind grows through interaction with the social environment.
Autism
A disorder that appears in childhood and is marked by significant deficiencies in communication and social interaction, and by rigidly fixated interests and repetitive behaviors.
cognition
all the mental abilities associated with thinking, knowing, remembering, and communicating
scaffold
In Vygotsky's theory, a framework that offers children temporary support as they develop higher levels of thinking.
attachment
An emotional time with another person; shown in young children by their seeking closeness to their caregiver and showing distress upon separation.
Heritability
involves variation among individuals in a group that we can attribute to genes. Depends on populations and changes in the environment. (how do genes cause a behavior?)
Molecular genetics
a subfield of biology that studies the molecular structure and function of genes.
Epigenetics
is above or in addition to genetics. The study of environmental influences on gene expression that occur without DNA change.
Gender Roles
are experiences behaviors, attitudes, and traits for males or females. Cultures shape our behaviors to behave in a particular social position.
Gender Identity
is one's own perception or sense of being male or female. NOT sexual orientation. (a person's feeling about their gender)

involves displaying both traditional masculine and feminine psychological characteristics.
Transgender
refers to individuals who have chosen to adopt dress and/or lifestyle that is opposite to their birth gender.

Moro reflex
an inborn extremely rapid response to a sudden unexpected stimulus.
Babinski reflex

Visual cliff
involves apparent, but not actual drop from one surface to another. This tool was originally developed to determine if infants had developed depth perception
Depth Perception
the ability to see objects in 3 dimensions although images that strike retina are 2 dimensional; allows us to judge distance
Harlow's monkey studies
Took monkeys away from their birth mothers and placed with two surrogate mothers. It was concluded that the monkeys were more likely to cling to the fluffy mother instead of the wire one even though the wire mother had food. Bonds because of bodily contact NOT nourishment
John Bowlby
discovered that attachment is characterized by specific behavior in children, such as seeking proximity with the attachment figure when upset or threatened.
Mary Ainsworth's Strange Situation experiment
Places a child under stress to test their attachment to their caregiver/mother. A child would begin to play with their mother, then a stranger would enter. After some engagement, the mother would leave and the child would cry. After some time the mother would come back and the reaction of the child (to either calm down, continue to cry, etc.) would determine the type of attachment to their mother.
Zone of proximal development
is the difference between what a learner can do without help and what they can do with help.
Konrad Lorenz
developed the idea of imprinting after experimenting with geese.
Imprinting
The process by which certain animals form attachments during the critical period very early in life.
Self-concept
a sense of one's identity and personal worth emerges gradually around 6 months. Around 15-18 months, children can recognize themselves in the mirror. By 8-10 years, their self image is stable.
facial recognition
an individual's understanding and interpretation of the face, particularly the human face, especially in relation to the associated information processing in the brain.
conscious memory/sense of self
the earliest age of conscious memory is around 3 1/2 years. A 5-year-old has a sense of self and an increased long-term memory, thus organization of memory is different from 3-4 years.
Secure attachment
when a child shows distress when a care giver leaves and is able to quickly compose themselves when the care giver returns.
Insecure avoidant attachment
in which people experience discomfort getting close to others and use avoidant strategies to maintain distance from others.
Insecure ambivalent attachment (anxious)
when people constantly crave acceptance but remane vigilant to signs of possible rejection.
Insecure attachment
marked by anxiety or avoidance. The infants will cling to their mothers and not look through the space. When their mothers leave they will become distressed and the baby will stay mostly the same when when the mother returns(in distress)
