A lexigram is a symbol or character that represents a word or concept. Depending on the context or field of study, there are alternative terms that can be used to refer to a lexigram. For example, in language studies, a lexigram may be called a grapheme or character. In computational linguistics and artificial intelligence, a lexigram may be referred to as an atomic symbol or symbol token. In psychology and animal behavior research, a lexigram is often called a visual symbol or stimulus object. Regardless of the terminology used, the basic principle behind a lexigram remains the same - it is a visual representation of language that can be used to communicate and convey meaning.
