This experimental study was conducted to determine if a treatment that stimulated the frontal lobe of the brain would have beneficial effects on patients with speech deficiencies. It was experimental rather than correlational because a change was introduced and its effects were monitored. Whereas in a correlational study a researcher would look for systematic relationships between variables that are already occurring. This experimental study also aims to prove that the reason the patients’ speech improved was because the pill caused it to. A correlational study would be unable to prove this because correlational studies cannot determine correlation, they can only measure the relationship between two variables.
Psychological studies are able to study many different things, but they all share a similar basic layout. Every study needs to

Broca’s area is located on the dominant side of the frontal lobe of the brain, and is most likely to have been influenced because it is linked to speech production. The frontal lobe is the largest of the four lobes of the brain and as such houses much more than Broca’s area. If the entire frontal lobe was to be stimulated changes would also occur in the primary motor cortex. This would result in changes in the patient’s coordination, and change how the brain plans and executes movements. The frontal lobe also determines our behavior so there is a chance that disrupting the normal state of the frontal lobe would change a patient’s personality. If the patient is experiencing symptoms that don’t involve speech function then the treatment has spread outside Broca’s area. The treatment must be negatively affecting the right side of the motor cortex because one hemisphere of the brain controls the opposite side of the body. It’s possible that patients are even experiencing minor strokes from the brain being overstimulated by the drug which is resulting in
