Higher Mental Functions of the Brain: Language

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...

Language Development

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...

Sensorimotor Stage II: Substages 4 to 6

Piaget’s sensorimotor stage describes cognitive development from birth to approximately two years. During this stage, infants progress from reflexive behavior toward intentional action and early symbolic thought. Substages four through six show major advances in problem-solving, experimentation, and mental representation.Substage 4: Coordination of Secondary Circular ReactionsFrom approximately 8 to 12 months, infants begin coordinating previously learned behaviors to achieve specific goals.

First Words During Infancy and Toddlerhood: Part 1

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...

First Words During Infancy and Toddlerhood: Part 2

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...

First Sentences During Toddlerhood

Toddlerhood is a major stage in language development as children progress from single words to combinations that express more complex ideas.Words and GesturesBetween 12 and 18 months, toddlers may combine one spoken word with a gesture to communicate the meaning of a two-word phrase. For example, pointing to a shoe while saying “Mommy” may mean “Mommy’s shoe.” This shows the multimodal nature of early communication, in which speech, gestures, and body language work together.Telegraphic...
