There are two main theoretical traditions in semantics. One is based on realism, where meanings are described as relations between language and the world, often in terms of truth conditions. The other is cognitivistic, where meanings are identified with mental structures. This article presents some of the main ideas and theories within the cognitivist approach. A central tenet of cognitively oriented theories of meaning is that there are close connections between the meaning structures and other cognitive processes. In particular, parallels between semantics and visual processes have been studied. As a complement, the theory of embodied cognition focuses on the relation between actions and components of meaning. One of the main methods of representing cognitive meaning structures is to use images schemas and idealized cognitive models. Such schemas focus on spatial relations between various semantic elements. Images schemas are often constructed using Gestalt psychological notions, including those of trajector and landmark, corresponding to figure and ground. In this tradition, metaphors and metonymies are considered to be central meaning transforming processes. A related approach is force dynamics. Here, the semantic schemas are construed from forces and their relations rather than from spatial relations. Recent extensions involve cognitive representations of actions and events, which then form the basis for a semantics of verbs. A third approach is the theory of conceptual spaces. In this theory, meanings are represented as regions of semantic domains such as space, time, color, weight, size, and shape. For example, strong evidence exists that color words in a large variety of languages correspond to such regions. This approach has been extended to a general account of the semantics of some of the main word classes, including adjectives, verbs, and prepositions. The theory of conceptual spaces shows similarities to the older frame semantics and feature analysis, but it puts more emphasis on geometric structures. A general criticism against cognitive theories of semantics is that they only consider the meaning structures of individuals, but neglect the social aspects of semantics, that is, that meanings are shared within a community. Recent theoretical proposals counter this by suggesting that semantics should be seen as a meeting of minds, that is, communicative processes that lead to the alignment of meanings between individuals. On this approach, semantics is seen as a product of communication, constrained by the cognitive mechanisms of the individuals.

Neurolinguistics is devoted to the study of the language-brain relationship, using the methodologies of neuropsychology and cognitive neuroscience to investigate how linguistic categories are grounded in the brain. Although the brain infrastructure for language is invariable across cultures, neural networks might operate differently depending on language-specific features. In this respect, neurolinguistic research on the Romance languages, mostly French, Italian, and Spanish, proved key to progress the field, especially with specific reference to how the neural infrastructure for language works in the case of more richly inflected systems than English. Among the most popular domains of investigation are agreement patterns, where studies on Spanish and Italian showed that agreement across features and domains (e.g., number or gender agreement) engages partially different neural substrates. Also, studies measuring the electrophysiological response suggested that agreement processing is a composite mechanism involving different temporal steps. Another domain is the noun-verb distinction, where studies on the Romance languages indicated that the brain is more sensitive to the greater morphosyntactic engagement of verbs compared with nouns rather than to the grammatical class distinction per se. Concerning language disorders, the Romance languages shed new light on inflectional errors in aphasic speakers and contributed to revise the notion of agrammatism, which is not simply omission of morphemes but might involve incorrect substitution from the inflectional paradigm. Also, research in the Romance domain showed variation in degree and pattern of reading impairments due to language-specific segmental and suprasegmental features. Despite these important contributions, the Romance family, with its multitude of languages and dialects and a richly documented diachronic evolution, is a still underutilized ‘treasure house’ for neurolinguistic research, with significant room for investigations exploring the brain signatures of language variation in time and space and refining the linking between linguistic categories and neurobiological primitives.
