1. A method comprising: detecting an inaudible physiological reaction by a person to an instance of at least two instances of a displayed first content, the at least two instances of the first content having a common contextual attribute, the detecting being performed while the person is viewing at least one of the at least two instances of the displayed first content; determining a content attribute of the instance of the at least two instances of the displayed first content that is at least substantially absent from other instances of the at least two instances of the displayed first content; initiating a search for a second content using a search parameter corresponding to the detected inaudible physiological reaction and to the determined content attribute of the instance; selecting the second content from a result of the initiated search, the selecting being automated and performed at least in part with a processing device; and facilitating a display of the selected second content in a manner perceivable by the person.

The method of claim 1 , wherein the determining a content attribute of the instance of the at least two instances of the displayed first content that is at least substantially absent from other instances of the at least two instances of the displayed first content further includes: determining a content attribute of the instance of the at least two instances of the displayed first content that is at least substantially absent from other instances of the at least two instances of the displayed first content that is a sub-category of the common contextual attribute of the at least two instances of the displayed first content.
