While there are several competing theories in cognitive ability research, there is also growing consensus that abilities are best organized hierarchically. In other words, each of the many different components of cognitive ability involve different sets of skills and these components are typically organized according to similarities among the tasks/skills involved. On the most narrow level, it is often difficult to distinguish between the skills used to accomplish a given task, but on the broadest level (at the top of the hierarchy), general skill sets are more plainly evident. For example, the skills required for different types of verbal tasks are more similar than those required for verbal and spatial tasks.

The items given here include several different types and we are actively working to develop more. In order to keep the test short, each participant is only administered a subset of the question types. Current question types include Letter and Number Series, Matrix Reasoning, Three-Dimensional Rotations, Verbal Reasoning (which includes general knowledge, logic and arithmetic questions), Figural Analogies, Two-Dimensional Rotations, Compound Remote Associates, Additions and Subtractions, Propositional Reasoning, and Emotion Recognition.

At this time, we are only giving feedback based on your responses to the Letter and Number Series items, the Three-Dimensional Rotation items, the Matrix Reasoning items, and the Verbal Reasoning items. This is because we don't yet have a big enough sample to generate representative norms for the other item types. Your responses have contributed to the development of these norms for future test-takers.
