I need help with my research. I need it by 10/3/02. 
One page or a page and half is good.


Listed below are several statements related to research outcomes from
the field of Child Development.  For each statement answer the
questions below it.

Statements

a.      Fathers and mothers interact differently with their children,
with fathers generally displaying more physical interaction in their
play styles than mothers do.

1)     Would an experimental or a naturalistic observation research
design be better for obtaining this research outcome?  Explain why.

2)     Could this be explored with a cross sectional design or would
you need to do a longitudinal study?  Explain why you think either a
cross sectional design would be sufficient or why you think a
longitudinal design would be necessary.



b.     Preschool aged children generally have a memory span of 3 to 4
items while middle childhood aged children generally have a memory
span of 7 items.



1)     Would an experimental or survey research design be better for
obtaining this research outcome?  Explain why.

2)     Could this be explored with a cross sectional design or would
you need to do a longitudinal study?  Explain why you think either a
cross sectional design would be sufficient or why you think a
longitudinal design would be necessary.



c.      Young children from lower socioeconomic statuses have
benefited in their intelligence scores from exposure to early
educational programs such as Head Start.



1)     Would an experimental or a natural experimental research design
be better for obtaining this research outcome?  Explain why.

2)     Could this be explored with a cross sectional design or would
you need to use an accelerated longitudinal design?  Explain why you
think either a cross sectional design would be sufficient or why you
think an accelerated longitudinal design would be necessary.
