This paper focuses on the optimum use of representational space by words in speech and in the mental lexicon. In order to do this we draw the concept of entropy from information theory and use it to plot the information contour of words. We compare different representations of Spanish speech: a citation vs. a fastspeech transcription of a speech corpus and a dictionary lexicon vs. a speech lexi...

Mental lexicon plays a central role in human language competence and inspires the creation of new lexical resources. The traditional linguistic experiment methodwhich is used to exploremental lexicon has some disadvantages. Crowdsourcing has become a promising method to conduct linguistic experiments which enables us to explore mental lexicon in an efficient and economic way. We focus on the fe...

Lexical decision task in an event-related potential experiment was used in order to determine the organization of mental lexicon regarding the polimorphemic words: are they stored as unanalyzable items or as separate morphemes? The results indicate the later: while monomorphemic words elicit N400 component, usually related to lexical-semantic processing, prefixed words and prefixed pseudo-words...

This paper presents a network model of the mental lexicon and its formation. Models of word meaning typically postulate a network of nodes wi th connection strengths, or distances, that reflect semantic similarity, but seldom explain how the network is formed or how it could be represented in the brain. The model presented here is an attempt to address these questions. The network organizes sem...

A familiarity database was developed for about 80,000 Japanese words of which familiarity scores were rated by 32 Japanese adults using a 7-point scale in auditory, visual, and audio-visual modalities. Auditory, visual, and audio-visual stimulus words were selected from the database according to their word familiarity for size estimation of the mental lexicon. Sixty Japanese adults participated...
