Unit 2 (Chapter 3 & 4) Flashcards
Experience-expectant process
Brain development that occurs based on environmental experiences that all members of the species typically encounter. (Ex: Learning how to walk. Need stimulation and social cues)
Experience-dependent processes:
Brain development that occurs based on unique environmental stimuli shared only by individuals in particular environmental circumstances. (Ex: If an individual was not exposed and trained to weave a cultural basket at a young age, they would not have the same dexterity or ability as one has learned to at an early age.)
Gross-motor skill
A motor skill that relies on large muscles, such as those in the legs and arms.
Posture provides foundation
Fine motor skill
A motor skill that relies on small muscles, such as those in the fingers.
What has the cross-cultural study of early motor development revealed regarding gross motor and fine motor skills?
•Some scholar have questioned whether the timing of motor skills development is the same around the world
•Cross-cultural studies conducted in the 1950s through the 1970s found that African children sat independently, stood up, and walked earlier than U.S. infants.
oContemporary researchers tend to de-emphasize the earlier findings.
Poor research methodologies
Recent studies have failed to fully replicate the original findings.
The timing of motor development may not be as important an issue as was once thought. Children in all culture eventually learn how to walk, run, and play with the same level of enthusiasm and skill.
Posture
The way a person holds his or her body as a whole.
Sensorimotor stage
Piaget’s first stage of cognitive development, in which infants develop from reflex-driven organisms to more complex and symbolic thinkers.
• The key processes that drive the change from one substage to the next are assimilation and accommodation.
o These processes underlie the ongoing development of mental structures called schemes
Schemes
Mental structures that help us organize and process information.
What is object permanence and why is it significant?
Object permanence
The understanding that an object continues to exist even when it is not immediately present or visible.
o In order to have object permanence, the infant must be able to mentally represent the object for which they search. Once they have representational ability, they can search for an object that is outside her visual awareness.
What is the A-not-B error, and how is it related to object permanence?
A-not-B error
A mistake made by children in Piaget’s sensorimotor stage as they search for a hidden object in a location where it has been repeatedly placed but is no longer hidden.
Describe language development in terms of expressive and receptive abilities
Receptive language (comprehension)
Language that an infant understands but may not be able to produce.
• Requires only the ability to hear and process information
Expressive language (production)
Language that an infant can produce.
• Requires the ability to control and produce sounds, and cognitive awareness of the meaning of those sounds.
Sequence of expressive language
Crying
Cooing (1-2 months)
Babbling (6-8 months)
First words (10-12 months)
Holophrase
One-word utterances that express a complete thought or phrase.
Telegraphic speech
The creation of short phrases that convey meaning but lack some of the parts of speech that are necessary for a full and complete sentence.
Joint attention
The ability to direct the attention of a social partner to objects or events and, in turn, follow their attention-directing gestures, such as head-turning and pointing.
