Cognitive Ability, Intelligence Tests

Cognitive ability tests measure problem solving ability using numbers, words and symbols. All good tests of cognitive ability should be underpinned by widely recognised theory. The cognitive ability tests used by the right people are based on the theory of fluid and crystallized intelligence known as Gf/Gc theory (see e.g., Davies et al., 1998; Roberts & Stankov, 1999; Stankov et al., 2001). Gf/Gc theory is the most widely recognized approach to the assessment of cognitive ability. Tests that measure learning potential, working memory, speed of problem solving and general problem solving ability include:

• Attention Switching Test
  Measures working memory and fluid intelligence (Gf). Examines the ability to change or switch between different tasks.
• Matrices Test
  A test of fluid intelligence (Gf) designed to examine strategic thinking and logical reasoning. The matrices test helps examine a person's ability to solve more complex problems.
• Shadowing Task
  This test is a measure of attention switching and examines a person's ability to apply instructions given to them verbally through headphones. This test is designed for call and contact centre environments and is administered using a standard computer with headphones.
• Multi-Tasks
  A test of higher-level problem solving ability. This test is often referred to as a dual task, as it involves solving two problems simultaneously. Competing tasks are good predictors of management ability.
• Working Memory Test
  A test of fluid intelligence (Gf) designed to examine working memory skills. This test is presented in a dynamic (moving format).
• Clerical - Symbolic Comparison Test
  A measure of mental processing speed (Gs). Examines clerical and perceptual speed and checking ability.
• Number Series Test
  A measure of fluid intelligence (Gf) that examines problem solving ability and numerical fluency at an elementary level.
• Digit Sequence Test
  A measure of fluid intelligence (Gf) that examines general reasoning skills and numerical fluency.
• Arrow Sequence Test
  A measure of fluid intelligence (Gf) that examines sequential and spatial type reasoning skills.

Language / Verbal Ability Measures include:

• Word Reasoning Test
  A measure of crystallized intelligence (Gc) that examines knowledge of word meanings and language comprehension.
• OSP General Knowledge and Word Reasoning Test
  A measure of crystallized intelligence (Gc) that examines verbal reasoning skills and general knowledge.
• Reading Comprehension Test
  A measure of crystallized intelligence (Gc) that examines verbal critical reasoning skills.
