Area of Science:

Psychometrics
Developmental Psychology
Cognitive Assessment

Background:

Standardized intelligence tests are crucial for cross-cultural comparisons.
The Colored Progressive Matrices (CPM) is a widely used non-verbal intelligence test.
Understanding cognitive abilities in diverse populations requires normative data.

Purpose of the Study:

To establish normative data for the Colored Progressive Matrices in a Lithuanian child sample.
To compare the cognitive performance of Lithuanian children to British norms.
To investigate potential differences in intelligence scores across geographical regions.

Main Methods:

Data collection involved 259 children aged 8-12 years in Lithuania during 1999.
The Colored Progressive Matrices (CPM) test was administered to all participants.
Statistical analysis compared the Lithuanian sample's mean IQ to the British 1979 standardization sample, with adjustments for secular trends.

Main Results:

The mean IQ of the Lithuanian children, relative to the British 1979 standardization sample, was 92.2.
After adjusting for estimated secular increases in intelligence in Britain, the Lithuanian mean IQ was estimated at 90.
This suggests a slight but measurable difference in performance when compared to British norms.

Conclusions:

The study provides valuable psychometric data for the Colored Progressive Matrices in Lithuania.
The findings indicate that Lithuanian children's performance on the CPM is comparable to, but slightly lower than, British norms when adjusted for historical changes.
Further research could explore factors influencing these observed differences in cognitive assessment.
