The lexical route is the process whereby skilled readers can recognize known words by sight alone, through a "dictionary" lookup procedure. [ 1 ] [ 4 ] According to this model, every word a reader has learned is represented in a mental database of words and their pronunciations that resembles a dictionary, or internal lexicon.
An experiment was performed to assess fast mapping in adults with typical language abilities, disorders of spoken/written language (hDSWL), and adults with hDSWL and ADHD. The conclusion draws from the experiment revealed that adults with ADHD were the least accurate at "mapping semantic features and slower to respond to lexical labels."
The latter, semantic network theory, proposes the idea of spreading activation, which is a hypothetical mental process that takes place when one of the nodes in the semantic network is activated, and proposes three ways this is done: priming effects, neighborhood effects, and frequency effects, which have all been studied in depth over the years.
The primary evidence for this role of the MTG-TP is that patients with damage to this region (e.g., patients with semantic dementia or herpes simplex virus encephalitis) are reported [90] [91] with an impaired ability to describe visual and auditory objects and a tendency to commit semantic errors when naming objects (i.e., semantic paraphasia).
Lexical semantics (also known as lexicosemantics), as a subfield of linguistic semantics, is the study of word meanings. [ 1 ] [ 2 ] It includes the study of how words structure their meaning, how they act in grammar and compositionality , [ 1 ] and the relationships between the distinct senses and uses of a word.
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 ...
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.
This can be explained by models that do not assume a distinct level between the semantic and the phonological stages (and so lack a lemma representation). [3] During the process of language activation, lemma retrieval is the first step in lexical access. In this step, meaning and the syntactic elements of a lexical item are realized as the lemma.
