06 May Impulse Waves in Layers
Layered Model Just as the brain has areas with three to six distinct layers, a typical artificial neural systems (ANS) also has several layers. The example at right shows a network with three layers that illustrate a neural network‘s distributed architecture. The uniform circles connected by lines are symbolic of the state of an ANS at […]
03 May Up from Words to Sentences
Words and Sentences The game of Scrabble is completely about words. Crossword puzzles go from sentence or phrase to word. Our analytical approach begins with the word, but doesn’t stop there. From both the cognitive and computational perspectives, the sentence exhibits far more complexity and changeability than the word. At any given moment, the structure of […]
26 Apr Continuity of Learning
Production and Comprehension We know that comprehension and language production occur in different areas of the brain and occupy opposite ends of the continuum in the communicative model. The relative independence of the production and comprehension centers suggests one of three possibilities: Syntactic and lexical data are replicated in both the production and comprehension centers of […]
22 Apr Breaking Down Language Structure and Function
Grammar Acquisition Some experts suggest that a correctly formulated adult grammar is acquired by children on the basis of sentences they hear in their first few years (Pinker, 1984, p. 5). The proponents of this theory assume that a young child perceives sentence structure or is able to detect elements of grammatical structure – a […]
21 Apr Language Inherited
Language Acquisition How do children acquire language? How do they learn about grammar and productively apply its general rules to creating new utterances? Some attempts to explain this phenomenon have suggested that a set of grammar rules is innate. Advocates of this theory (Chomsky 1968) point to grammatical similarities, or universals, across languages and aver that a […]
19 Apr Learning by Doing or Active Osmosis
Intuition When people use their native language, they don’t usually think about how verbs are supposed to be conjugated. They don’t stop to figure out number agreement, transitivity, or aspect. They just talk. Intuitions about language are probably not based on the grammar rules that govern how parts of speech go together. Instead, these intuitions […]
18 Apr Irrational Language Rules
Language and Utterances Now let’s narrow the focus from communication to language. To avoid confusion, let it be clear from the outset that this discussion is not concerned with computer-programming languages, but “natural languages.” Computer languages have built-in or “prescriptive” regularity called a formal syntax. They are easy to describe, and they are obedient to […]
17 Apr Learning by Repetition
Frequency and Exposure For the very young, language learning requires mental gymnastics. Most theories of language learning refer to the fact that the frequency of repetition of a word or structure pattern determines the strength of its acquisition. In this context, there may be some threshold of frequency which, once reached, will result in the […]
16 Apr From Concept to Communication
Yorrick’s First Concepts A conceptually structured model of learning might suggest that Yorrick, or any other human, first acquires concepts, and later, a vehicle for communicating concepts: language. During Yorrick’s early development, his concepts are linked entirely to physical sensations and perceptions: hunger, soreness, the sucking instinct, and the like. One of the first discoveries […]
14 Apr Translation: Inverted Communication
Lately I’ve been concentrating on modeling communicative skills. Whether speaking, signing, gesturing or writing, we begin with intent and wrap symbols around the intent or message to encode it. Translating and encrypting start with a fully encoded message, and unwrap it, before rewrapping it in a different form that is intended to preserve the original intent. Translation is an application […]
