UNL PSYCH 289 Exam 2 Questions With
Correct Answers
What does it mean that cortical organization is lateralized and plastic? - CORRECT
| | | | | | | | | | | | |
ANSWER✔✔-Lateralized means certain functions are on one side of the brain | | | | | | | | | |
Plasticity means that the brain can still learn new things, and that neurons can
| | | | | | | | | | | | | |
take on new functions
| | |
Neuron - CORRECT ANSWER✔✔-a specialized cell transmitting nerve impulses; a
| | | | | | | | | |
nerve cell. |
Axon - CORRECT ANSWER✔✔-the neuron extension that passes messages
| | | | | | | | |
through its branches to other neurons or to muscles or glands
| | | | | | | | | |
Cell body - CORRECT ANSWER✔✔-Largest part of a typical neuron; contains the
| | | | | | | | | | | |
nucleus and much of the cytoplasm
| | | | |
Dendrite - CORRECT ANSWER✔✔-Branchlike parts of a neuron that are
| | | | | | | | | |
specialized to receive information. | | |
Myelinization - CORRECT ANSWER✔✔-Insulation of axons, speeds transmission of
| | | | | | | |
neural impulses
| |
What is migration? - CORRECT ANSWER✔✔-Cells move from one part of the
| | | | | | | | | | | |
brain to another.
| |
, What are sensitive periods? - CORRECT ANSWER✔✔-Periods where stimulation is
| | | | | | | | |
vital when the brain is growing rapidly
| | | | | | |
What is experience-expectant brain growth and experience-dependent brain
| | | | | | | |
growth? - CORRECT ANSWER✔✔-Experience - EXPECTANT growth: ordinary
| | | | | | | |
experiences expected by the brain to grow normally (vision)
| | | | | | | |
Experience - DEPENDENT growth: additional growth as a result of specific
| | | | | | | | | | |
learning experiences (violin lessons)
| | |
What are two principles of motor development? - CORRECT ANSWER✔✔-
| | | | | | | | |
Cephalocaudal- head to toe (head develops first) | | | | | | |
Proximodistal- general motor skills tend to develop before fine motor skills
| | | | | | | | | | |
(moving your arm before grabbing a pencil)
| | | | | |
Describe gross motor development and fine motor development. How do they
| | | | | | | | | | |
differ? - CORRECT ANSWER✔✔-Gross motor- involves large muscle groups such
| | | | | | | | | |
as walking
|
Fine motor- uses small muscle groups like to grab a pencil
| | | | | | | | | |
Describe the dynamic systems theory of motor development. - CORRECT
| | | | | | | | | |
ANSWER✔✔-Movement is a result as the complex interactions between many | | | | | | | | | |
complex subsystems in the body and the environment.
| | | | | | |
Describe the general progression of locomotion, including average ages. -
| | | | | | | | | |
CORRECT ANSWER✔✔-Crawls- 5-11 months| | |
Stands alone- 9-16 months
| | |
