Encoding is the process by which information gets input into the memory system.
It involves the brain labeling sensory information received from the environment through automatic or effortful processing.
Automatic processing unconsciously encodes details like time and the meaning of words.
Effortful processing requires significant work and attention to encode information, like learning a new language or understanding a new subject.
There are three types of encoding — semantic, visual, and acoustic.
Semantic encoding involves the encoding of words and their meanings. For example, associating the word tree with its characteristics—having a single tall trunk, branches, and leaves—enhances its retention.
Visual encoding is the encoding of images. For instance, reading the words car and book generates mental images of these objects.
Acoustic encoding involves storing and recalling sounds, particularly words. For example, the lyrics of an old song can be remembered due to the stored sounds of the words.
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the…
