What are the two broad scores generated by the Wechsler Adult Intelligence Scale 4?

1. Full Scale IQ and General Cognitive Index

2. Full Scale Intelligent Quotient and General Ability Index

3. General Ability Index and Verbal IQ

4. Working Memory Index and Processing Speed Index

The correct answer is: Full Scale Intelligent Quotient and General Ability Index

The Wechsler Adult Intelligence Scale (WAIS) is designed to assess a person's intellectual ability and is comprised of several components leading to two primary scores. The correct answer identifies these scores as the Full Scale Intelligent Quotient (FSIQ) and the General Ability Index (GAI). The Full Scale IQ provides a comprehensive measure of an individual's overall intellectual functioning and reflects their performance across all areas of cognitive ability tested in the WAIS. This score is significant as it summarizes the individual’s general cognitive capacity. On the other hand, the General Ability Index is computed based on a subset of the tests that primarily measure cognitive abilities excluding certain working memory and processing speed factors. The GAI is valuable in cases where performance on tasks may be influenced by specific issues such as learning disabilities, allowing for a clearer picture of an individual's cognitive strengths and weaknesses. Understanding these two scores is crucial for interpreting the WAIS assessment accurately, as they offer insights into different dimensions of intelligence, thus benefiting the comprehensive evaluation process in rehabilitation counseling and psychological evaluation.
