Historical records indicate that the Binet-Simon scale was first published in 1905. The provided option C (1990) is historically inaccurate. This entry is flagged due to a conflict between the provided answer key and established historical facts regarding the development of intelligence testing.

Lewis Terman, a psychologist at Stanford University, adapted the original Binet-Simon intelligence scale for use in the United States. His revision, known as the Stanford-Binet Intelligence Scale, became one of the most widely used and influential tests for measuring cognitive ability and intelligence, introducing the concept of the Intelligence Quotient (IQ) to the American public.

Modern IQ tests are standardized with a mean score of 100 and a standard deviation of 15. Therefore, a score of 115 is exactly one standard deviation above the mean. This indicates that the individual performed better than approximately 84% of the population, placing them in the above-average range, but not at the level typically classified as genius.

The Wechsler Adult Intelligence Scale (WAIS) and its counterparts for children (WISC and WPPSI) are currently the most frequently administered individual intelligence tests in clinical and educational settings. They are preferred for their comprehensive structure, which provides both a full-scale IQ score and specific index scores for different cognitive domains, offering a detailed profile of an individual's intellectual strengths and weaknesses.

The Wechsler Adult Intelligence Scale (WAIS) is specifically designed for adults and includes subtests such as Digit Span (working memory), Vocabulary (verbal comprehension), and Object Assembly (perceptual reasoning). These specific subtests are hallmark components of the WAIS battery used to evaluate adult cognitive functioning.

Vocational aptitude tests are designed to measure an individual's latent potential or capacity to learn specific skills required for certain occupations. Unlike achievement tests that measure current knowledge or skills, aptitude tests focus on predicting future performance and identifying the career paths where an individual is most likely to succeed based on their inherent strengths.

Factor analysis is a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors. In the context of intelligence, it is used to identify the underlying components or 'factors' that contribute to overall cognitive performance, helping researchers understand the structure of human intelligence.

The term 'biased' in psychometrics often refers to how test items may favor individuals from specific cultural backgrounds. Because intelligence tests are constructed using language, symbols, and concepts familiar to the dominant culture, individuals from different cultural backgrounds may perform differently, not necessarily due to a lack of intelligence, but due to a lack of familiarity with the specific cultural content presented in the test items.

The WAIS is specifically designed to measure cognitive ability and intelligence in adolescents and adults, typically ranging from ages 16 to 90. It provides a comprehensive assessment of various cognitive domains, including verbal comprehension, perceptual reasoning, working memory, and processing speed, which are distinct from the scales used for younger children.

An achievement test is designed to measure what a person has learned or mastered through instruction or experience. Unlike aptitude tests, which predict future potential or ability to learn, achievement tests evaluate current knowledge. Examples include standardized tests in school subjects, which confirm that a student has acquired the necessary information from a specific curriculum.
