Language Development

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...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Components of Language

Components 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.

Higher Mental Functions of the Brain: Language

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...

Subliminal Perception

Subliminal Perception

Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Area of Science:

Child Development
Educational Psychology
Linguistics

Background:

Decoding skills are foundational for literacy acquisition.
Transparent languages, like Brazilian Portuguese, facilitate early decoding.
Understanding factors influencing decoding is crucial for educational interventions.

Purpose of the Study:

To investigate decoding processes in relation to age in Brazilian Portuguese-speaking children.
To examine the impact of grade level, stimulus type, and stimulus length on decoding accuracy.
To explore the multifactorial nature of decoding acquisition in young learners.

Main Methods:

A study involving 250 children aged 6-10 years, from 1st to 5th grade.
Utilized a computer-based assessment (E-prime®) to present words and pseudowords of varying lengths.
Data collected on decoding accuracy for stimuli based on Brazilian Portuguese structure.

Main Results:

Identified distinct phases of decoding: acquisition and mastery.
Found significant effects of stimulus extent and type, interacting with school progress.
Confirmed the multifactorial nature of decoding acquisition and variable interactions.

Conclusions:

Decoding acquisition is a complex process influenced by multiple factors.
Educational progress and stimulus characteristics significantly impact decoding skills.
Findings inform strategies for improving decoding abilities in children.
