Based on the experiments conducted on the function, I can observe some patterns. The function output is higher for words associated with emotions/feelings, such as love, happiness, or anger. Moreover, the function seems to give higher values for words with more abstract or less physical implications, like freedom or exotic. Still, it doesn't entirely ignore other concepts, like animals, objects or nature. 

[DESCRIPTION]: The function f(x) is primarily selective for emotions/feelings and abstract concepts. However, it also assigns values to various other concepts, including animals, objects, and natural phenomena, typically with low to medium association strengths.
