What are the four principles of growth?
Cephalocaudal principleProximodistal principle
Principle of Hierarchial integration
Independence of systems
what are the four principles of growth
- cephalocaudal pattern - "head to tail" growth, starts w/ the head & continues down - proximodistal pattern - development starts w/ center of body outward - hierarchical integration - simple skills develop, then more complex ones - independence of systems - diff. body systems grow at different rates
when skills and actions go unused, synaptic connections can become weaker and weaker and eventually die off. The result of Synaptic Pruning is to allow established neurons to build a more elaborate communication network with other neurons. use it or lose it
a fatty substance that helps insulate neurons and speeds the transformation of nerve impulses
What are rhythms and states?
Rhythm-repetivie cyclic patterns of behavior -may go through periods in which they jerk their legs in a regular pattern every minute
State-the degree of awareness an infant displays to both internal and external stimulation -alternes, fussing, and crying, different levels of sleep

Information Processing Model-Encoding, Storage, and Retrieval
Like a computer, memories are made through three processes. In encoding, the memory is processed into the memory system. It is like typing in words into a word document. In storage, the memory is retained over time. Retrieval marks the process of getting the information out of storage.

Implicit: Cerebellum and brain stem Explicit: Hippocampus and increasing amounts of the cortex.
When does explicit and implicit memory emerge?

How are norms used in studying or assessing child development?
Norms represent the average performance of a large sample of children of a given age and are used to make broad generalizations about the timing of various behaviors and skills.
Secure Attachment Pattern
a style of attachment in which children use mother as a home base and are at ease as long as she is present; when she leaves they become upset and go to her as soon as she returns
avoidant attachment pattern
a style of attachment in which children do not seek proximity tot he mother; after the mother has left, they seem to avoid her when she returns as if they are angered by her behavior
ambivalent attachment pattern
a style of attachment in which children display a combination of attachment in which children displa a combination of positive and negative reactions to their mothers; they show great distress when the mother leaves, but upon her return they any be simultaneously seek close contact but also hit and kick her.
disorganized disoriented attachment pattern
a style of attachment in which children show inconsistent often contradictory behavior such as approaching the mother when she returns bu not looking at her, they may be the least securely attached children of all
have a positive disposition; their body functions operate regularly and they are adaptable.
negative moods and are slow to adapt to new situations; when confronted with a new situation, they tend to withdraw.
babies who are inactive, showing relatively calm reactions to their enviroment; their moods are generally negative, and they withdraw from new situations, adapting slowly
rapid eye movement stage of sleep in which the eyes move rapidly under the eyelids and the person is typically experiencing a dream. Infants < 6 months usually experience a Rem-like sleep for 1/2 the time they sleep. 6< the amount is 1/3 the time they sleep is REM-like.
