These six researchers collected their data by separating the group of pregnant rats into four different groups. These groups included a control group which was normal …show more content…
The six researchers began with a hypothesis, studied multiple conditions in which could cause their hypothesis to be supported or rejected. Their conclusion on the effects are reasonable, since development is the pattern of continuity and change that occurs throughout a lifetime. The rats were exposed to abnormal conditions in which they weren’t conditioned too, causing their development to change. Also, early experience has a greater impact on development, therefore the researchers using rats that were newly born was essential to the experimental process to compare the
