Analyse A Portrait of the Artist as a Young Man according to the narrative techniques?
As pointed out already, the key term for reading Portrait of the Artist is stream of consciousness. In stream of consciousness, a narrator follows directly the psychological experience of a character. This can make the reading rather difficult sometimes, and so in Portrait, we may have to slog through some of the more intense rambling. If you take a look at Joyce's later books, Ulysses and Finnegan's Wake, you'll see the technique taken to its extreme, and most readers would call both of those novels unreadable (although a lot of readers love them).
In Portrait, he uses the stream of consciousness in a very clever way, and you will notice it if you look closely at the grammar, the syntax, and the vocabulary as it develops. You'll see that the style of the narration shifts as the character grows from a toddler to a moody college student. Our first experience with the novel gives us a very childish, nursery-rhyme styled description of a little boy watching cows, made mostly of short, simplistic sentences and infantile wording, such as "tuckoo" and "moocow." By the time we get to the end, we're looking up words in the dictionary as we read the protagonist's long, brooding sentences, packed full of literary and cultural references, sexual implications, philosophical speculations, and questions of guilt and sin and family obligations.
One of the reasons Joyce is considered such a master is the skill with which he manipulated his writing style in this novel to fit the age and the state of mind of his protagonist. The over-arching characteristic of the style in this novel is how it changes throughout.
