Q

Immunizations

A

A process that stimulates the body’s immune system by causing production of antibodies to defend against attack by a particular contagious disease.
Antibodies can be created either naturally (by catching/having the disease), by injection, or by drops that are swallowed, or by a nasal spray.

Q

Language Acquisition Device (LAD)

Q

Mean Length of Utterance (MLU)

A

The average number of words in a typical sentence (called utterance b/c children may not talk in complete sentences). MLU is often used to measure language development.

16
Q

Prefrontal Cortex

A

The area of the cortex at the very front of the brain that specializes in anticipation, planning, and impulse control.

17
Q

Primary Circular Reactions

A

Sensorimotor Intelligence stage 1 & 2
The first of 3 types of feedback loops in sensorimotor intelligence, this one involving the infant’s own body. The infant senses motion, sucking, noise, and other stimuli and tries to understand them.

18
Q

Secondary Circular Reaction

A

Sensorimotor Intelligence stage 3 & 4
The first of 3 types of feedback loops in sensorimotor intelligence, involving the infant an object or another person, as with shaking a rattle or playing peek-a-boo.

19
Q

Sensorimotor Intelligence

A

Piaget’s term for the way infants think-by using their senses and motor skills-during the first period of cognitive development. (6 Stages)

20
Q

Shaken Baby Syndrome

A

A life-threatening injury that occurs when an infant is forcefully shaken back and forth, a motion that ruptures blood vessels in the brain and breaks neural connections.

21
Q

Sudden Infant Death Syndrome (SIDS)

A

A situation in which a seemingly healthy infant (2-6 months) suddenly stops breathing and dies unexpectedly while asleep.

22
Q

Synapse

A

The intersection between the axon of one neuron and the dendrites of other neurons.

23
Q

Tertiary Circular Reaction

A

Sensorimotor Intelligence stage 5 & 6
Piaget’s description of the cognitive processes of the 1 yr old, who gathers information from experiences with the wider world and then acts on it. The response to those actions leads to further understanding, which makes this circular. “Little Scientist”

24
Q

Transient Exuberance

A

The great but temporary increase in the number of dendrites that develop in an infant’s brain during the first two years of life.

25
Q

Stunting

A

The failure of children to grow to a normal height for their age due to severe and chronic malnutrition

26
Q

Wasting

A

The tendency for children to be severely underweight for their age as a result of malnutrition

27
Q

Protein-Calorie Malnutrition

A

A condition in which a person does not consume sufficient food of any kind. This deprivation can result in several illnesses, severe weight loss, and even death.

28
Q

Implicit Memory

A

Memory that isn’t verbal, often unconscious. Many motor and emotional memories are implicit.

29
Q

Explicit Memory

A

Memory that can be recalled in the conscious mind, usually factual memories that are expressed with words.

30
Q

Object Permanence

A

The realization that objects (and people) still exist when they can no longer be seen, touched, or heard

31
Q

Language Development Milestones

A

Crying - Immediately
Cooing - 2 Months
Babbling- 6 Months
Gestures - 10-12 Months
First Words - 10-15 Months (usually 1st b-day)
Naming Explosion - 18 Months
Patterned Speech - 12-24 Months (1-2yrs)
Two-Word Utterances - 21 Months
Multiword- 24 Months (2yr)

32
Q

Bed-Sharing

A

When two or more people sleep in the same bed.

33
Q

Co-sleeping

A

A custom in which parents and their children (usually infants) sleep together in the same room.

34
Q

Head-sparing

A

A biological mechanism that protects the brain when malnutrition disrupts body growth. The brain is the last part of the body to be damaged by malnutrition.
