Research example 4:
The title of this peer reviewed article is “Aesthetics” by Ethel Puffer Howes. This article talks about aesthetics, and what people find to be aesthetically pleasing. It continues to discuss the psychological analysis of aesthetics specifically how the brain reacts to different aesthetic experiences. There are many types of aesthetics, be it in art or economy. The author explains that you cannot compress all the aspects of aesthetics into a single formula, it consists of a many elements.
The topic of this article is aesthetics and the research question would be: what elements make up aesthetics?
In order to gather this data, you would need to either survey people and ask them, “what elements make up aesthetics?” Or you would need to discuss aesthetics with an expert- asking what makes something aesthetically pleasing.
This research is much more conceptual than any other readings I have come across. It takes a unique stance on the various elements and tools that make something aesthetically pleasing.
It is a secondary source because it takes the information from other peoples research and studies.
