Verbal-performance discrepancies: relationship to birth risk and specific reading retardation
Summary
Verbal-performance discrepancies in children are not strongly linked to early risks but impact reading ability differently based on how reading difficulties are defined. This study examines the complex relationship between cognitive skills and reading outcomes.
Area of Science:
- Child Psychology
- Neurodevelopmental Disorders
- Educational Psychology
Background:
- Assessing cognitive development in children is crucial for understanding learning abilities.
- Verbal-performance discrepancies on intelligence tests may indicate underlying developmental differences.
- Specific reading retardation is a complex condition with varied definitions and potential etiological factors.
Purpose of the Study:
- To investigate the relationship between verbal-performance discrepancies in children and early risk factors.
- To examine the predictive value of these discrepancies for reading ability.
- To explore the impact of different definitions of specific reading retardation on observed relationships.
Main Methods:
- Longitudinal assessment of 169 children using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) at 4.5 years and the Wechsler Intelligence Scale for Children-Revised (WISC-R) at 8.5 years.
- Collection of retrospective data on perinatal risk factors and childhood neurological disease.
- Analysis of correlations between cognitive scores, risk factors, and reading ability.
Main Results:
- Verbal-performance discrepancies at 4.5 years showed no significant association with perinatal risks, neurological disease, or later reading ability.
- A weak correlation was found between WISC-R verbal-performance discrepancies and perinatal history.
- Verbal IQ (VIQ) at 8.5 years correlated more strongly with reading ability than Performance IQ (PIQ).
Conclusions:
- Early cognitive discrepancies do not strongly predict later reading ability or risk factors.
- The relationship between cognitive discrepancies and specific reading retardation is contingent upon the precise definition of reading retardation used.
- Further clarification is needed regarding the definition and assessment of specific reading retardation.

01:52Regression Toward the Mean
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
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...

01:27Language 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.
01:30Oppositional Defiant Disorder
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
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.
