Summary
Individuals with closed head injury (CHI) struggle with understanding indirect language and show poorer executive function. Pragmatic judgment deficits in CHI are linked to executive skill impairments, particularly inhibition.
Area of Science:
- Neuroscience
- Psychology
- Linguistics
Background:
- Closed head injury (CHI) often leads to executive skill deficits.
- Difficulties in social interactions are common after CHI.
- Pragmatic language comprehension is crucial for successful social interaction.
Purpose of the Study:
- To investigate pragmatic judgment in individuals with CHI.
- To explore the relationship between pragmatic skills and executive functions after CHI.
Main Methods:
- A pragmatic inference task was administered to CHI patients and a healthy control group.
- Participants judged the social appropriateness of vignette responses.
- Non-social executive tasks were performed to assess executive functions.
Main Results:
- The CHI group demonstrated poorer performance on the pragmatic task compared to controls.
- CHI patients showed reduced ability to distinguish literal from indirect interpretations.
- Impairments in non-social executive tasks were observed in the CHI group.
- A significant association was found between pragmatic performance and inhibition.
Conclusions:
- Individuals with CHI exhibit deficits in pragmatic judgment.
- Executive skills, particularly inhibition, are associated with pragmatic abilities after CHI.
- Further research is needed to elucidate the precise relationship between executive functions and pragmatic skills in CHI.

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

01:24Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
