Identifying Intelligence Tests for Illiterate Adults

The question asks to identify intelligence tests suitable for illiterate adults. This means the tests should rely minimally on verbal comprehension and reading skills.

Analysis of Intelligence Tests

• Wechsler Adult Intelligence Scale (WAIS): This test includes significant verbal subtests (e.g., vocabulary, comprehension) and requires understanding written or spoken instructions, making it unsuitable for illiterate individuals.
• Alexander Pass Along Test: This is a non-verbal, performance-based test. It assesses reasoning and problem-solving through tasks involving moving colored blocks, requiring minimal language comprehension. Therefore, it is applicable to illiterate adults.
• Coloured Progressive Matrices (CPM): While CPM is a non-verbal test designed to be culturally fair, it requires abstract reasoning and pattern completion based on visual matrices. Although less language-dependent than WAIS, understanding the task structure might still pose challenges for completely illiterate adults compared to purely performance-based tests. The provided correct answer implies it's not the best fit.
• Koh’s Block Design Test: This test involves arranging colored blocks to replicate specific designs shown in pictures. It is a purely non-verbal, performance-based assessment, making it highly suitable for individuals with limited or no literacy skills, including illiterate adults.

Conclusion on Applicable Tests

Based on the analysis, the tests most applicable to illiterate adults are those that are non-verbal and performance-based:

• Alexander Pass Along Test ((b))
• Koh’s Block Design Test ((d))

Therefore, the correct option includes tests (b) and (d) only.
