In popular usage, aphenomenon often refers to an extraordinary, unusual or notable event. According to theDictionary of Visual Discourse:[2]
In ordinary language 'phenomenon/phenomena' refer to any occurrence worthy of note and investigation, typically an untoward or unusual event, person or fact that is of special significance or otherwise notable.
In modern philosophical use, the termphenomena means things as they are experienced through the senses and processed by the mind as distinct from things in and of themselves (noumena). In hisinaugural dissertation, titledOn theForm and Principles of the Sensible and Intelligible World,Immanuel Kant (1770) theorizes that the human mind is restricted to the logical world and thus can only interpret and understand occurrences according to their physical appearances. He wrote that humans could infer only as much as their senses allowed, but not experience the actual object itself.[3] Thus, the termphenomenon refers to any incident deserving of inquiry and investigation, especially processes and events which are particularly unusual or of distinctive importance.[2]

Innatural sciences, a phenomenon is an observable happening or event. Often, this term is used without considering the causes of a particular event. Example of a physical phenomenon is an observable phenomenon of the lunar orbit or the phenomenon of oscillations of a pendulum.[4]
Group phenomena concern the behavior of a particular group of individual entities, usually organisms and most especially people. The behavior of individuals often changes in a group setting in various ways, and a group may have its own behaviors not possible for an individual because of theherd mentality.
Social phenomena apply especially to organisms and people in that subjective states are implicit in the term. Attitudes and events particular to a group may have effects beyond the group, and either be adapted by the larger society, or seen as aberrant, being punished or shunned.
