The Basics
Nutting spoke about the psychological / physiological lab in the basement of the Al Neuharth Media Center, also known as the COMPARE Lab. This stands for communication, media psychology and related effects.
Nutting is one of two professors involved with the lab. A handful of graduate and undergraduate students assist in the process of collecting physiological and psychological responses to different forms of media. The room where all of this happens is located in a basement, however, Nutting says the space is "perfect" for their current needs.
First, the administrators of the tests hook the subject up to sensors, which can monitor heart rate, skin conductors, and other involuntary responses.
“When it comes to physiological responses, your body cannot lie,” Nutting said.
The subject is then placed in a large, brown chair, and is exposed to various forms of media, and the results are compiled, and eventually published in academic journals.
The Difference
Even though Nutting's passion lies with research, there's one particular kind he isn't particularly fond of: qualitative. Qualitative research tends to involve data collection that's more anecdotal, without a hard set of numbers and facts. This type of research also involves typically smaller sample sizes. With qualitative research, subjects are able to alter their decisions based on what other people think, and other outside sources, which has the potential to skew results.
On the other hand, quantitative research puts numbers to everything, meaning a concrete calculation is never far from reach. This type of research tends to deal with larger sample sizes. With this type of data collection, everything is measurable, and there is no denying the numbers that manifest from the research. These numbers are counting things like heart rate and visual perception.
“I like to count things. I don’t see the value
in five people telling me they were traumatized,” Nutting said.
For example, if Nutting conducted research by asking 20 people if they were scared of a horror movie, this would be qualitative research. Conversely, if Nutting were to individually test 100 people by making them watch a horror movie while hooked up to the COMPARE Lab's sensors, he could physically see the subjects' change in heart rate and other factors to determine if they were affected at all. This would be an example of quantitative research.
Although his interests reside with strictly quantitative data collection, Nutting does believe that qualitative data has its place. For instance, Nutting says creating focus groups and using that information to conduct quantitative research is beneficial.
