Speech acts are communicative actions that perform a function, such as making a request, giving an order, or making a promise, through the use of language. They highlight the pragmatic aspect of language, where meaning is not only derived from words and grammar but also from the context and intention behind the utterance.
Conversational implicature refers to the phenomenon where the speaker implies something beyond the literal meaning of their words, relying on shared knowledge and context to convey additional meaning. This concept is central to understanding how communication often relies on unspoken assumptions and the ability of listeners to infer intentions and meanings not explicitly stated.
Theory of Mind is the cognitive ability to attribute mental states such as beliefs, intents, and desires to oneself and others, allowing for the prediction and understanding of others' behaviors. This capacity is crucial for social interactions and is typically developed in early childhood, with deficits often seen in conditions like autism spectrum disorder.
