Exam 2 Flashcards
From the upper head to the lower body
Cephalocaudal development
From the trunk out from the central axis to periphery
Proximodistal
The tendency for behavior to become less loose and diffuse and more specific and distant
Differentiation
Infants usually double their birth weight in about 5 months and triple it in
1 year
Height increases by around
50% in first year
Growth occurs in
Spurts
Infants grow in second year
4-6 inch , gain 4-7 lbs
Girls mature
Earlier
Children’s heads are proportionately
Larger
Impairs growth in infancy, includes low birth weight, bmi
Failure to thrive
Organic based FTT
Underlying health problem
Non organic , non biological FTT
Psychological roots
Children less likely securely attached to the mothers, large family, unstable environment,
Reactive attachment disorder
A form of FFT involving malnutrition , life threatening,
Marasmus

41%
Solid foods often introduced at
4-6 months
Breast milk ughout
1st year
First solid food is usually iron- enriched
Cereal, then strained fruits, vegetables
Breastfeeding is the
Natural way
Early form of breast milk
Colostrum
Colostrum
High in proteins, Carrie’s antibodies, reduces maternal risk of breast cancer , builds maternal bone strength
Newborns prefer breast milk rather
Formula
Disadvantages of breastfeeding
Breast milk can transmit hiv, alcohol, drugs, no environmental hazards , mothers must be adequately nourished
Breast milk remains ideal even if mother
Smokes
Basic units of nervous system
Neurons
Each neuron has
Cell body, dendrites, and axon
Axon terminals release messages in the form of chemicals called
Neurotransmitters
Many neurons are tightly wrapped with white fatty
Myelin sheaths
Process of myelin coating axons
Myelintion
Developing organisms command center
Brain
Brain of neonate weighs less than
1 pound
Vital in control of heartbeat , part of brain stem
Medulla
Above medulla, helps maintain balance, coordination
Cerebellum
Enables human learning, thought , memory
Cerebrum
First major growth spurt
Prenatally, fourth and fifth months of gestation
Second growth spurt
Between 25th week of gestation and end of second year , dendrites and axon terminals proliferate, connections between neurons
Begins around 6 moth

Perception of object as the same despite sensations it produces varying under different conditions
Perceptual constancy
Perception of object as the same size despite different retinal image sizes due to distance
Size constancy
Perception of object as the same shape despite different retinal image shapes due to viewing from different positions
Shape constancy
Neonates can orient their heads. In the direction of
Sound
Absorbing new events into existing schemes (mental constructs)
Assimilation
Modifying existing schemes if assimilation cannot make sense of novel events
Accommodation
recognition that an object/person continues to exist when out of sight
Object permanence
Absorbing new events into existing schemes (mental constructs)
Assimilation
Modifying existing schemes if assimilation cannot make sense of novel events
Accommodation

Four stages
Cognitive processes develop in an orderly sequence of four stages:
–Sensorimotor, preoperational, concrete operational, and formal operations
