Lexical access and literacy in children with word-finding difficulties
1Childhood Development & Learning, Open University, Milton Keynes, UK. d.j.messer@open.ac.uk
Summary
Children with word-finding difficulties exhibit slow serial naming speeds, impacting literacy. Serial naming tasks involving letters and digits correlate strongly with reading and decoding abilities, suggesting structural task similarities.
Area of Science:
- Child psychology
- Neuroscience
- Speech-language pathology
Background:
- Investigating lexical access in children with word-finding difficulties.
- Examining serial naming speed and its relation to literacy.
Purpose of the Study:
- Assess serial naming speed in children with word-finding difficulties.
- Determine the relationship between serial and discrete naming tasks.
- Test predictions from the double-deficit hypothesis.
Main Methods:
- Eighteen children with word-finding difficulties participated.
- Naming and literacy tasks were administered at 8;6 years.
- Literacy tasks were re-administered at 9;8 years.
Main Results:
- Children demonstrated significantly slow serial naming speeds.
- Serial and discrete naming speeds were not strongly correlated.
- Serial naming of alphanumeric items showed the strongest literacy correlations.
Conclusions:
- Serial and discrete naming tasks measure different aspects of lexical access.
- Partial support for the double-deficit hypothesis was found.
- Task structure similarity may explain the link between serial naming and literacy.

01:25Learning Disabilities
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.

01:27Language 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.
01:21Health Literacy
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative programs,...
01:22Language 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...

01:10Higher 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...

01:10Tip-of-the-Tongue Phenomenon
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...
