Semantic structure in the mental lexicon is often assumed to follow a taxonomic structure grouping similar items. This study uses a network clustering analysis of a massive word association dataset that does not primarily focus on concrete noun categories, but includes the majority of the words used in daily life. At this scale, we found widespread overlap between thematically organized cluster...

Although for many years a sharp distinction has been made in language research between rules and words-with primary interest on rules-this distinction is now blurred in many theories. If anything, the focus of attention has shifted in recent years in favor of words. Results from many different areas of language research suggest that the lexicon is representationally rich, that it is the source ...

Abstract The mental lexicon stores words and information about words. is seen by many researchers as a network, where lexical units are nodes the different links between connections. Based on analysis of word association in this article we show that kinds associative connections exist lexicon. Our based database from agglutinative language Hungarian. We use communities – closely knit groups to ...

Cognitive neuroscience has gained significant insight into the mechanisms underlying mental lexicon and their impact on second language vocabulary learning. However, relatively little effort been put understanding how these may instructional practices. We attempt to bridge this gap. Towards that end, we first describe three main properties of lexicon: words have distinct form meaning representa...

For certain disable persons unable to communicate, we present a palliative aid which consist of a virtual pictographic keyboard associated to a text processing from a pictographic scripture. Words and the grammar are given as pictograms. The pictographic lexicon must be organized following the mental lexicon of the user to propose the pictograms of grammar in order to facilitate his task of wri...

The present study examined how the network science measure known as closeness centrality (which measures the average distance between a node and all other nodes in the network) influences lexical processing. In the mental lexicon, a word such as CAN has high closeness centrality, because it is close to many other words in the lexicon. Whereas, a word such as CURE has low closeness centrality be...

Recent work has proposed using network science to analyse the structure of the mental lexicon by viewing words as nodes in a phonological network, with edges connecting words that differ by a single phoneme. Comparing the structure of phonological networks across different languages could provide insights into linguistic typology and the cognitive pressures that shape language acquisition, evol...

Are the linguistic forms that are memorized in the mental lexicon and those that are specified by the rules of grammar subserved by distinct neurocognitive systems or by a single computational system with relatively broad anatomic distribution? On a dual-system view, the productive -ed-suffixation of English regular past tense forms (e.g., look-looked) depends upon the mental grammar, whereas i...

This thesis investigated the fundamental representations within the mental-lexicon and whether such representations are fixed or differ according to the characteristics of various languages. It looked at whether syllable structure is represented at distinct levels of linguistic representation at phonological and phonetic levels, with phonology governed by the demands of a combinatorial system (...
