Sensorium

A sensorium (plural: sensoria) is the sum of an organism's perception, the "seat of sensation" where it experiences and interprets the environments within which it lives. The term originally entered English from the Late Latin in the mid-17th century, from the stem sens- ("sense"). In earlier use it referred, in a broader sense, to the brain as the mind's organ (Oxford English Dictionary 1989). In medical, psychological, and physiological discourse it has come to refer to the total character of the unique and changing sensory environments perceived by individuals. These include the sensation, perception, and interpretation of information about the world around us by using faculties of the mind such as senses, phenomenal and psychological perception, cognition, and intelligence.

Ratios of sensation

In the 20th century the sensorium became a key part of the theories of Marshall McLuhan, Edmund Carpenter and Walter J. Ong (Carpenter and McLuhan 1960; Ong 1991).

McLuhan, like his mentor Harold Innis, believed that media were biased according to time and space. He paid particular attention to what he called the sensorium, or the effects of media on our senses, positing that media affect us by manipulating the ratio of our senses. For example, the alphabet stresses the sense of sight, which in turn causes us to think in linear, objective terms. The medium of the alphabet thus has the effect of reshaping the way in which we, collectively and individually, perceive and understand our environment in what has been termed the Alphabet Effect.

Choice

Choice involves mentally making a decision: judging the merits of multiple options and selecting one or more of them. One can make a choice between imagined options ("what would I do if ...?") or between real options followed by the corresponding action. For example, a traveller might choose a route for a journey based on the preference of arriving at a given destination as soon as possible. The preferred (and therefore chosen) route can then follow from information such as the length of each of the possible routes, traffic conditions, etc. If the arrival at a choice includes more complex motivators, cognition, instinct and feeling can become more intertwined.

Simple choices might include what to eat for dinner or what to wear on a Saturday morning - choices that have relatively low-impact on the chooser's life overall. More complex choices might involve (for example) what candidate to vote for in an election, what profession to pursue, a life partner, etc. - choices based on multiple influences and having larger ramifications.
