What is the greatest limitation of experimental studies in studying development?

options:

Subjects are not randomly assigned to conditions.

They are too complex to carry out correctly.

Most of the causal variables of interest to developmentalists cannot be manipulated.

They cannot detect cause-effect relationships.

Solution

The greatest limitation of experimental studies in studying development is that \"most of the casual variables of interest to developmentalists cannot be manipulated\". As the researchers focusing on most specific independent variables to find out the changes in dependent variables for the final conclusion, they must be permitted to do it in any ways. But the fact is that in most of the studies the researchers cannot do the work at expecting time because they cannot manipulate independent varuables due to many reasons like ethical reasons, practical reasons etc. This is one of the best disadvantage or limitation.
