Summary
The Computer-Assisted Bilingual Vocabulary Instruction (CABVI) program effectively boosts Spanish vocabulary for dual language learners (DLLs). Bilingual CABVI also supports English vocabulary growth, with gains maintained over time.
Area of Science:
- Speech and Language Pathology
- Educational Technology
- Bilingual Education
Background:
- Dual language learners (DLLs) require effective vocabulary interventions.
- Technology-assisted learning offers potential for language acquisition.
- Understanding the impact of instructional language is crucial for DLLs.
Purpose of the Study:
- To evaluate the preliminary efficacy of the Computer-Assisted Bilingual Vocabulary Instruction (CABVI) program.
- To assess CABVI's impact on Spanish and English vocabulary acquisition in DLLs.
- To investigate how the language of instruction influences vocabulary outcomes.
Main Methods:
- Twenty-one preschoolers were randomized into bilingual CABVI, English-only CABVI, or business-as-usual groups.
- CABVI utilized explicit instruction, audio prompting, interactive reading, and word-focused activities.
- Vocabulary was assessed using receptive, naming, and definition tasks at pretest, posttest, and follow-up.
Main Results:
- Bilingual CABVI significantly improved Spanish vocabulary compared to other groups.
- Both intervention groups showed comparable English vocabulary gains.
- Vocabulary improvements in both languages were maintained at the 6-week follow-up.
Conclusions:
- Bilingual CABVI offers a structured approach to enhance DLL vocabulary development.
- Technology-based bilingual programs show promise for improving language learning.
- Findings can inform clinical practices for supporting DLLs' linguistic needs.

01:27Language and Cognition
704
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.

01:25Learning Disabilities
567
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

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...

01:24Components of Language
746
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.

01:28Lateralization
960
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

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...
