a) A study design (e.g., correlation, experiment, quasi-experiment).
The study chosen depends on what you want to find out. Correlation is when you want to find out if there is a relationship between two things (chewing gum increases tests scores); not one causes the other. Experiment is when you manipulate the situation, when you want to cause something to happen (prove your hypothesis). Randomly give treatment to some in the group and does not get the treatment to the others; a dependent (what changes or has an effect) and independent (what is controlled) variable. A quasi-experiment is similar to experiment except the groups are not randomly assigned.
Divide group into two teams and assign one as control and one as experiment.

b) Methods for conducting the experiment (i.e., how would you propose to study their ...

Hi, I need help with the 2 questions below. Thanks for any help you could provide.

1- Many states, in recent years have changed their laws so that children who commit violent crimes, such as murder can be charged as adults. Thinking about Piaget's findings on how children develop reasoning skills, discuss the following: How old do you think a person needs to be to know the difference between right and wrong and to know that murder is wrong? What should be the youngest cutoff age to hold a person who kills another person legally responsible for the crime of murder?

2- Observe young children playing, either in your own family, or in public settings. Based on the games they play and George Herbert Meadâ??s theory of the development of the self, can you tell if they are in the play or game stage? Post your observations here.
