Infants are born with a predisposition to perceive and categorize basic linguistic sounds. Early in development, they can discriminate sounds from many languages and detect differences in rhythm and pattern. This sensitivity may begin before birth. Newborns exposed to two languages prenatally can recognize both, indicating that fetal language exposure influences later auditory discrimination.Recognition of Familiar SoundsBy five months, infants show preferences for familiar auditory stimuli,...

Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of information more...

Early language development begins with receptive vocabulary, the words children understand before they can speak. By about 18 months, many children understand roughly 150 words and produce about 50. Children with larger vocabularies and faster processing may recognize words from their initial sounds. For example, hearing “daw” may prompt identification of a dog, showing sensitivity to phonological cues.Growth of Expressive VocabularyExpressive vocabulary, or spoken vocabulary, develops...

Language development in infancy progresses from understanding words to producing meaningful speech. Infants use contextual and social cues to connect sounds with meanings and gradually expand their vocabulary.Word Recognition Before SpeechInfants understand words before they can say them. By about six months, they may look toward a familiar object, such as a banana, when hearing its name. This receptive vocabulary provides a foundation for later speech.First Words and Linguistic SpeechMost...

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. “eh”). Phonemes combine to...
