Development Flashcards
Conception
Merger of DNA from a single male sperm (1 out of 200 million) and the female egg in the ovary
Zygote
the egg then shuts out the rest of the sperm and the nuclei combine for a unique DNA sequence
Gestation Period
the period of development and growth
of the fetus/child from conception to birth.
Teratogen
an agent such as a chemical or virus that can harm the embryo during embryotic development. Some examples include drugs, alcohol, chicken pox, arsenic, lead, toxic chemicals, etc. Such teratogens can result in physical handicaps, deformation, behavioral issues, and diminished cognitive abilities.
Fetal Alcohol Syndrome
can result in an epigenetic effect on the genes of the fetus, resulting in both physical and cognitive abnormalities that follow the child for the rest of their life. A teratogen from too much alcohol exposure
Maturation
he biological growth processes that enables orderly changes in behavior.
Schemas
mental representations
Stranger Anxiety
when around strangers, and absent their parents or another
familiar face, babies become anxious, less comfortable playing, and prone to crying. Happens around 8 months old when a schema for mom and dad has formed
Attachment Bond
dependent emotional connection to a parent that can be seen in a child’s behavior around age 1. Discovered by Mary Ainsworth
Basic Trust
a sensitive, loving, caring attitude of trust rather than fear of other people, as well as a positive sense of self & others. Discovered by Erik Erikson
Self-Concept
a concrete idea of who they are and how they feel about who they are. From 12-18, most continue to develop their identities and assimilate them into society. Studied by Erik Erikson
Critical Period
the optimal period early in life of an organism when exposure to certain stimuli or experiences produces normal development.
Imprinting
the process by which certain animals form strong attachments during an early-life critical period. Imprinting is often developed at a young age in animals. Not in humans? Research done by Konrad Lorenz— ducks can imprint to anything
Temperament
one’s characteristic emotional reactivity and intensity—is also largely hereditary.
Difficult Babies
Irritable, intense, and unpredictable babies
Easy Babies
cheerful, relaxed, and predictable in feeding and sleeping
Jean Piaget’s Sensorimotor Stage
0-2. during which infants know the world mostly in terms of their sensory impressions and motor activities. Lacked object permanence at the start. Object permanence and separation anxiety develop during this stage.
Jean Piaget’s Preoperational Stage
2-6/7. During which a child learns to use language but does not yet comprehend the mental operations of concrete logic. Uses symbols (words and images) to represent objects. Child is egocentric. 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.
Jean Piaget’s Concrete Operational Stage
7-11/12. During which children gain the mental operations that enable them to think logically about concrete events. Child understands conservation.
Jean Piaget’s Formal Operational Stage
12- adult. During which people begin to reason abstractly and think in hypothetical terms.
Autism Spectrum Disorder (ASD)
A disorder that appears in childhood and is marked by significant deficiencies in communication and social interactions, and by rigidly fixated interests and repetitive behaviors
Harry and Margaret Harlow’s Research
Gave monkeys a wire feeding mother and a soft nonfeeding mother. The monkeys gained attachment to the soft mother.
