Lifespan Development Exam 2(100%
Verified!)
How do different parts of the brain vary in their development? - ANSWERSleft brain grows in spurts while
the right brain grows more gradually. Frontal cortex is growing rapidly
How do these changes get reflected in verbal and nonverbal behaviors? - ANSWERSlanguage skills
(typically housed in the left hemisphere) increase rapidly in early childhood and they support children's
increasing control over behavior. [in contrast, spatial skills develop gradually over childhood and
adolescence]
What are some influences on handedness? - ANSWERSLow inheritance
Prenatal influences
Practice effects
What hormones influence physical growth? - ANSWERSGrowth hormone (HGH) and TSH (Thyroid
Stimulating Hormone)
What is psychosocial dwarfism and how does it develop? - ANSWERSa growth disorder; usually appears
between 2 and 15 years old; caused by extreme emotional deprivation
it is characterized by decreased growth hormone secretion, very short stature, immature skeletal age,
and serious adjustment problems, which help distinguish it from normal shortness
Why is immunization important? - ANSWERSImmunizations greatly reduce the chance of acquiring
certain preventable diseases (which can spread fast in children who are not immunized)
How is fine motor development reflected in drawing skills? - ANSWERSScribbles
First representational forms (age 3)
"tadpole" image
More realistic drawings (5-6)
, How might social development be reflected in the development of drawing ability? - ANSWERSwhat and
how children draw is a direct reflection of their life experiences
In which Piagetian stage are early childhood folks usually in? - ANSWERSpreoperational
What types of thought processes typify this stage? (2-6 years) What cognitive processes are they still
lacking? - ANSWERSMental representations, increase in symbolic activity, and dual representation.
Deficient in egocentrism, lack of Hierarchical classification, animistic thinking, inability to conserve, and
irreversibility.
Is there evidence that Piaget was mistaken again? What is this evidence? - ANSWERSYes, he was still
underestimating kids' mental process and he also underestimated what age kids can achieve things
What is fast mapping? - ANSWERSchild's ability to connect new words with their underlying concepts
after only a brief encounter
What are some of the constraints on fast mapping? - ANSWERSJoint attention
Constraints on word names
Sentence Cues
Cognitive Factors
Hippocampus - ANSWERSan inner brain structure that plays a vital role in memory and in images of
space that help us find our way
Corpus Callosum - ANSWERSa large bundle of fibers connecting the two cerebral hemispheres
Reticular Formation - ANSWERSa structure in the brain stem that maintains alertness/attention and
consciousness
Cerebellum - ANSWERSbrain structure at the rear and base of the brain that aids in balance and control
of body movement. Also plays a roles in memory, planning, language
