<strong>Semiotics</strong> <strong>for</strong> <strong>Beginners</strong> <strong>by</strong> <strong>Daniel</strong> <strong>Chandler</strong><br />

dimensions into two. For those who do not, this little experiment may be quite surprising. We are<br />

routinely anaesthetized to a psychological mechanism called 'perceptual constancy' which stabilizes<br />

the relative shifts in the apparent shapes and sizes of people and objects in the world around us as<br />

we change our visual viewpoints in relation to them. Without mechanisms such as categorization and<br />

perceptual constancy the world would be no more than what William James called a 'great blooming<br />

and buzzing confusion' (James 1890, 488). Perceptual constancy ensures that 'the variability of the<br />

everyday world becomes translated <strong>by</strong> reference to less variable codes. The environment becomes a<br />

text to be read like any other text' (Nichols 1981, 26):<br />

Key differences between 'bracketed' perception and everyday perception may be summarized as<br />

follows (Nichols 1981, 13, 20):<br />

Bracketed Perception Normal Perception<br />

A bounded visual space, oval, approximately<br />

180° laterally, 150° vertically<br />

Clarity of focus at only one point with a<br />

gradient of increasing vagueness toward the<br />

margin (clarity of focus corresponds to the<br />

space whose light falls upon the fovea)<br />

Parallel lines appear to converge: the lateral<br />

sides of a rectangular surface extending away<br />

from the viewer appear to converge<br />

If the head is moved, the shapes of objects<br />

appear to be de<strong>for</strong>med<br />

The visual space appears to lack depth<br />

A world of patterns and sensation, of<br />

surfaces, edges and gradients<br />

Unbounded visual space<br />

Clarity of focus throughout<br />

Parallel lines extend without<br />

converging: the sides of a<br />

rectangular surface extending<br />

away from the viewer remain<br />

parallel<br />

If the head is moved, shapes<br />

remain constant<br />

Visual space is never wholly<br />

depthless<br />

A world of familiar objects and<br />

meaning<br />

The conventions of codes represent a social dimension in semiotics: a code is a set of practices<br />

familiar to users of the medium operating within a broad cultural framework. Indeed, as Stuart Hall<br />

puts it, 'there is no intelligible discourse without the operation of a code' (Hall 1980, 131). Society<br />

itself depends on the existence of such signifying systems.<br />

Codes are not simply 'conventions' of communication but rather procedural systems of related<br />

conventions which operate in certain domains. Codes organize signs into meaningful systems which<br />

correlate signifiers and signifieds. Codes transcend single texts, linking them together in an<br />

interpretative framework. Stephen Heath notes that 'while every code is a system, not every system is<br />

a code' (Heath 1981, 130). He adds that 'a code is distinguished <strong>by</strong> its coherence, its homogeneity,
