The cohort model relies on several concepts in the theory of lexical retrieval. The lexicon is the store of words in a person's mind; [3] it contains a person's vocabulary and is similar to a mental dictionary. A lexical entry is all the information about a word and the lexical storage is the way the items are stored for peak retrieval.
Bilingual lexical access is an area of psycholinguistics that studies the activation or retrieval process of the mental lexicon for bilingual people.. Bilingual lexical access can be understood as all aspects of the word processing, including all of the mental activity from the time when a word from one language is perceived to the time when all its lexical knowledge from the target language ...
Lemma retrieval is aided by the activation level of the concept that has yet to be verbalized. When activation takes place on the lemma level, the highest activated lemma element is selected. [5] Lexical selection experiments have provided evidence that lemma retrieval is affected by the frequency of the word. [6]
A model of the mental lexicon adapted from Stille et al. (2020) In the sample model of the mental lexicon pictured to the right, the mental lexicon is split into three parts under a hierarchical structure: the concept network (semantics), which is ranked above the lemma network (morphosyntax), which in turn is ranked above the phonological network.
According to the lexical access model (see section below), in terms of lexical access, two different stages of cognition are employed; thus, this concept is known as the two-stage theory of lexical access. The first stage, lexical selection provides information about lexical items required to construct the functional level representation.
A major area of study, psycholinguistics and neurolinguistics, involves the question of how words are retrieved from the mental lexical corpus in online language processing and production. For example, the cohort model seeks to describe lexical retrieval in terms of segment-by-segment activation of competing lexical entries. [3] [4]
The blocking hypothesis states that retrieval cues elicit the retrieval of a word related to the target that then blocks the retrieval of the correct word and causes the tip of the tongue phenomenon to occur. [2] In other words, TOTs occur when plausible but incorrect responses to a query come to mind quickly.
A lexical database is a lexical resource which has an associated software environment database which permits access to its contents. The database may be custom-designed for the lexical information or a general-purpose database into which lexical information has been entered.
