Chpt 3 (Body and Mind) [Infant] Flashcards
Body Changes, The Eager Mind, Language: What develops in the first 2 years, Survivng and Thriving
Axon
A fiber that extends from a neuron and transmits electrochemical impulses transmitted from other neurons via their neurons.
Babbling
An infant’s repetition of certain syllables that begins when babies are between 6-9 months. (Ba-ba-ba for example)
Cortex
The outer layers of the brain in humans and other mammals. Most thinking, feeling, and sensing involves the cortex.
Dendrite
A fiber that extends from a neuron and receives electrochemical impulses transmitted from other neurons via their axons.
Fine Motor Skills
Physical abilities involving small body movements (Fine=Small)
Gross Motor Skill
Physical abilities involving large body movements (Gross= Big)
Holophrase
A single word that is used to express a complete, meaningful thought.
(Dada, Dada?, Dada!)
Immunizations
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.
Language Acquisition Device (LAD)
Chomsky’s term for a hypothesized mental structure that enables humans to learn language, including the basic aspects of grammar, vocab, and intonation.
‘Little Scientist’
Piaget’s term for toddlers insatiable curiosity and active experimentation as they engage in various actions to understand their world.
Mean Length of Utterance (MLU)
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.
Motor Skill
The learned abilities to move some part of the body. (The word motor= Movement of muscles)
Naming explosion
A sudden increase in an infant’s vocabulary, especially in the number of nouns- 18 months
Neuron
One of billions of nerve cells in the central nervous system (CNS), especially in the brain.
Neurotransmitter
A brain chemical that carries information from the axon of a sending neuron to the dendrites of a receiving neuron.
