Requires intensive time and resource investment
Since researchers have limited control over independent variables, the cause of a behavior can't be fully determined
The data gathered is specific to one individual
The ability to study major medical events and other personal information to a depth that would otherwise be impossible
Data can be collected quickly, and from a large number of people
By altering conditions precisely, researchers can determine causality rather than causation
Allows researchers to investigate the brain, itself
Data gathered reflects people's typical behavior in a normal environment without researcher interference
Gathering data requires specialized equipment
Results can only reflect participants' perceptions rather than objective truths
