Term
Nature vs. Nurture
Definition
Nature- inborn, biological givens, based on genetic inheritance

Differentiation Theory 

Definition

Infants:

      • search for invariant features of the environment

        • visual patterns, intermodal relationships
      • gradually detect finer and finer features 
        • differentiation
Term
Social Learning Theory
Definition
an approach that emphasizes the role of modeling, or observational learning, in the development of behavior

Definition
a type of genetic-envrionmental correlation in which individuals actively choose environments that complement their heredity.
Term

 

Meiosis

Definition
The process of cell division through which gametes are formed and in which the number of chromosomes in each cell is halved.
Term
Prenatal Testing
Definition
Medical procedures that permit detection of developmental problems before birth.
Term

Sudden infant death syndrome

(SIDS)

Definition
The unexpected death, usually during the night, or an infant under 1 year of age that remains unexplained after thorough investigation
Term

 

Fetal monitor

Definition
Electronic instruments that track the baby's heart rate during labor
Term

 

Umbilical Cord

Definition
The long cord connecting the prenatal organism to the placenta that delivers nutrients and removes waste products
Term

 

Fetal alcohol syndrome

Definition
A set of defects that results when women consume large amounts of alcohol during most or all of pregnancy. Includes mental retardation; impaired motor coordination, attention, memory, and language; overactivity; slow physical growth; and facial abnormalities.

Term
Attachment theory- Bowlby
Definition
Attachment theory describes the dynamics of long-term relationships between humans. Its most important tenet is that an infant needs to develop a relationship with at least one primary caregiver for social and emotional development to occur normally. Attachment theory explains how much the parents' relationship with the child influences development. 
Term
Conception
Definition
  • Formation of a viable zygote by the union of the male sperm and female ovum; fertilization.
  • The entity formed by the union of the male sperm and female ovum; an embryo or zygote.
Term

 

Weight gain during pregnancy

Definition

There's no one-size-fits-all approach to pregnancy weight gain. How much weight you need to gain depends on various factors, including your pre-pregnancy weight and body mass index (BMI). Your health and your baby's health also play a role. Work with your health care provider to determine what's right for you.

 
Term
Kangaroo Care
Definition
 is a technique practiced on newborn, usually preterm, infants wherein the infant is held, skin-to-skin, with an adult. Kangaroo care for pre-term infants may be restricted to a few hours per day, but if they are medically stable that time may be extended. 
Term
Range of Reaction
Definition
this concept identifies that each person has a genetically determined response to his/her environment unique to that person. Reaction Range exemplifies the fact that each person will react differently to an external stimulus and sometimes, although each person's genetic makeup is unique, different genetic and environmental combinations can make two people look alike in their reaction ranges
Term
Perceptual Development
Definition
Infants’ perceptual skills are at work during every waking moment. For example, those skills can be observed when an infant gazes into a caregiver’s eyes or distinguishes between familiar and unfamiliar people. Infants use perception to distinguish features of the environment, such as height, depth, and color.
Term

 

Body growth during infancy and toddlerhood

Definition

Physical growth occurs rapidly during the first 2 years of life. The transition from infancy to toddlerhood - the period that spans the second year of life-is marked by the infant's switch from crawling to walking.

 1. During the first 2 years, the body grows more rapidly than at any time after birth.
   2. By the end of the first year the infant's length is 50 percent greater than it was at birth, 
        and by 2 years of age it is 75 percent greater.
   3. Birth weight has doubled by 5 months of age, tripled by I year, and quadrupled at 2 years.
   4. Research indicates that these height and weight gains occur in little growth spurts.
   5. In infancy, girls are slightly shorter and lighter than boys.

Term

 

Brain development during infancy and toddlerhood

Definition
  • The available evidence suggests that both genetic processes and early experiences with the environment influence the timing of brain development
  • Some suggest that the entire infancy period is a crucial and sensitive time for brain development, given the quantity and speed at which the neurons develop and connect. 
  • Positive physical experiences (feeding, safety, etc.) and positive psychological experiences (touching,cooing, and playing) activate and simulate brain activity 
Term
Sensory capacities
Definition
  • Full-term infants are born with a functioning sensory system—the senses of hearing, sight, taste, smell, touch, and sensitivity to pain—and these abilities continue to develop rapidly in the first few months
