In the broadest sense, a code is a (learnt, or arbitrary, or conventional) correspondence or rule between patterns. It can be an arrangement of physical matter, including the electromagnetic spectrum, that stores the potential (when activated) to convey meaning (or a pre-specified result). [1]
Encoding, in semiotics, is the process of creating a message for transmission by an addresser to an addressee. The complementary process – interpreting a message received from an addresser – is called decoding .
The encoding specificity principle is the general principle that matching the encoding contexts of information at recall assists in the retrieval of episodic memories. It provides a framework for understanding how the conditions present while encoding information relate to memory and recall of that information.
In the field of cognitive psychology, mental representations refer to patterns of neural activity that encode abstract concepts or representational “copies” of sensory information from the outside world. [11] For example, our iconic memory can store a brief sensory copy of visual information, lasting a fraction of a second. This allows the ...
If the word is recalled, the image of the dog is not lost and can still be retrieved at a later point in time. The ability to code a stimulus two different ways increases the chance of remembering that item compared to if the stimulus was only coded one way. There has been controversy to the limitations of the dual-coding theory.
Temporal coding allows the sequence 000111000111 to mean something different from 001100110011, even though the mean firing rate is the same for both sequences, at 6 spikes/10 ms. [24] Until recently, scientists had put the most emphasis on rate encoding as an explanation for post-synaptic potential patterns.
A modern-day example of the dominant-hegemonic code is described by communication scholar Garrett Castleberry in his article "Understanding Stuart Hall's 'Encoding/Decoding' Through AMC's Breaking Bad". Castleberry argues that there is a dominant-hegemonic "position held by the entertainment industry that illegal drug side-effects cause less ...
The earliest examples of color codes in use are for long-distance communication by use of flags, as in semaphore communication. [1] The United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety, with other colors having similar assignments of meaning.
