Cross-sequential Research Design
question
the union of the ovum and sperm.
answer
Fertilization
question
1. identical twins formed when one zygote splits into two seperate masses of cells, each of which develops into a seperate embryo. 2. often called fraternal twins, occuring when two eggs each get fertilized by two different sperm, resulting in two zygotes in the uterus at the same time.
answer
Difference between 1. Monozygotic twins & 2. Dizygotic Twins
question
* Germinal Period - first two weeks after fertilization, during which the zygote moves down to the uterus. * Embryonic Period - (2-8 weeks) essential features are established. Most sensitive to environmental influences. * Fetal Period - (9 wks-birth) changes in size and functioning of organs. 7 months (28 weeks) Viability - fetus could live independently outside the womb.

Schemes
question
assimilation - when you first try to understand new things in terms of schemes. ex. a child might see an orange and say "apple" because both objects are round. accommodation - is the process of altering or adjusting old schemes to fit new information and experiences. ex. when corrected, the child might alter the scheme for apple to include "round" and "red".

Stage 1 of Piaget's Cognitive Development
question
Preoperational - (2 to 7 yrs old) - young children can mentally represent and refer to objects and events with words or pictures and they can pretend. However, they can't conserve, logically reason, or simultaneously consider many characteristics of an object.

Stage 2 of Piaget's Cognitive Developement
question
Concrete Operations - (7 to 12 yrs) - children at this stage are able to conserve, reverse their thinking, and classify objects in terms of their many characteristics. They can also think logically and understand analogies but only about concrete events.
answer
Stage 3 of Piaget's Cognitive Developement
question
Formal Operations - (12 yrs to adulthood) - People at this stage can use abstract reasoning about hypothetical events or situations, think about logical possibilites, use abstract analogies, and systematically examine and test hypotheses. Not everyone can eventually reason in all these ways.

answer
Ainsworth's study & types of attachment
question
believed that development occurred in a series of eight stages, with the first four of these stages occurring in infancy and childhood. Each stage is an emotional crisis, or a kind of turning point, in personality, and the crisis in each stage must be successfully met for normal, healthy psychological development.
answer
Focus of Erikson's Theory

question
babies are almost the opposite of easy babies. these babies tend to be irregular in their schedules and are very unhappy about change of any kind. they are loud, active, and tend to be crabby rather than happy.
