PSY1012 FINAL EXAM QUESTIONS
AND CORRECT REVIEWED ANSWERS
causes of intellectual disability
~30-40% of cases, no known biological problem can be
identified.
1.) Familial Intellectual Disability: Occurs mostly in very
poor households where nutrition, intellectual stimulation,
medical care & emotional support may be inadequate
2.) Metabolic Disorders: affect energy production & use in
the body.
3.) Genetic Abnormalities: Missing genes, Extra genes, &
Defective genes
4.) Malnutrition & Exposure to Lead, Polychlorinated
biphenyls (PCBs), & other toxins early in childhood can
also cause organic intellectual disability.
5. ) Down Syndrome: Causes moderate to severe
intellectual disability & a shortened life expectancy of
around 49 years.
6.) Fragile X Syndrome: hereditary; the problem is related
to a thin fragile looking area on the x chromosome. Boys
are more often affected ( 1 out of 5000).
, 7.) Phenylketonuria (PKU): plagues children who lack an
important enzyme. This causes phenylpyruvic acid ( a
destructive chemical) to collect within their bodies.
8.) Microcephaly: "small headedness" The microcephalic
person suffers a rare abnormality in which the skull is
extremely small or fails to grow.
9.) Hydrocephaly: "Water on the brain" caused by a
buildup of cerebrospinal fluid within brain cavities
10.) Cretinism: Appears in infancy. Results from an
insufficient supply of thyroid hormone. Iodized salt has
made this source of intellectual disability rare in developed
nations. (pg. 298-300)
Common barriers to problem solving.
1. Emotional Barriers: Inhibition and fear of making a fool
out of oneself
2. Cultural Barriers: values that hold that fantasy is a
waste of time; playfulness is for children only; reason,
logic, & numbers are good.
3. Learned Barriers: Conventions about uses, meanings,
possibilities, and taboos
4. Personal Barriers: Habits leading to failure to identify
important elements of a problem (Pg. 276)
Alfred Binet
Wanted to find a way to distinguish slower students
from the more capable. (pg. 290)
Who invented the first intelligence test and for what
reason?
