What is included in the Perceptual Reasoning Index?

1. Digit Span and Arithmetic

2. Block Design and Picture Completion

3. Symbol Search and Coding

4. Matrix Reasoning and Cancellation

The correct answer is: Block Design and Picture Completion

The Perceptual Reasoning Index (PRI) is a component of the Wechsler intelligence scales that measures non-verbal and fluid reasoning abilities. It assesses a person's capacity to perceive, analyze, and solve problems related to visual information. Block Design involves arranging blocks to match a given pattern, which tests spatial visualization skills and the ability to see relationships between parts and wholes. Picture Completion assesses the ability to identify missing elements in pictures, which reflects visual perception and detail orientation. Both of these tasks require the participant to interpret visual information and use reasoning skills effectively. The other options consist of tasks that assess different cognitive abilities. For instance, Digit Span and Arithmetic relate more closely to working memory and verbal processing rather than perceptual reasoning. Similarly, Symbol Search and Coding focus on processing speed and associative memory, and Matrix Reasoning and Cancellation involve different perceptual and cognitive skills not exclusive to visual reasoning. Therefore, Block Design and Picture Completion are the correct components reflecting the skills measured by the Perceptual Reasoning Index.
