3 ITAB IT Aptitude Battery The ITAB is the worlds first battery of fully interactive tests of human intelligence. A product of: CogniMetrics, Inc. San Antonio, TX What is the ITAB? © CogniMetrics, Inc., 2006

4 ITAB IT Aptitude Battery The Navy Mission requires its personnel to be able to operate a great variety of technical systems. The cognitive skill required for using such systems is called procedural knowledge, or procedural skill. Traditional tests of intelligence, such as the ASVAB, were not designed to measure aptitude for procedural skill learning. ITAB and the U.S. Navy © CogniMetrics, Inc., 2006

5 ITAB procedural skills Procedural skill is knowledge that a person uses to interact with a physical, or conceptual, system to achieve a particular goal. What is procedural skill? © CogniMetrics, Inc., 2006

6 Procedural skills vary in complexity from performing operator maintenance on a M16A1 rifle, to preparing board weapon systems for operation, to operating board weapon systems, and to remotely controlling UAVs. Cognition research in the nineties has deepened our insight into how procedural skills are learned. Examples of procedural skill ITAB procedural skills © CogniMetrics, Inc., 2006

7 ITAB tests The ITAB tests measure the aptitude to learn procedural skills (procedural knowledge). We will refer to this aptitude as PKL aptitude (procedural knowledge learning aptitude). Measurement purpose © CogniMetrics, Inc., 2006

8 ITAB tests ITAB 1: Hidden Target Test Task: The Interface of the Hidden Target test generates a two-dimensional search space consisting of a rectangular grid of equally spaced horizontal and vertical lines. The subject is required to determine where a target is located in as few steps as possible. The subject can move a cursor across the two-dimensional space from junction to junction using a set of arrow keys. To indicate his or her first guess the subject clicks at the key. The feedback of the task-environment indicates the distance between the tested location and the location of the hidden target in City Block metric.. bar keys HELP menu © CogniMetrics, Inc., 2006

9 ITAB tests ITAB 2: Battery Test Task: the test requires the individual to test whether the presented batteries work. Each new trial starts with a set of nine batteries to be tested. The battery tester is designed such that batteries have to be tested in pairs. The goal of the task is to identify the defective batteries in as few steps as possible. Each set of nine batteries contains two defective batteries. HELP MENU button Feedback window © CogniMetrics, Inc., 2006

10 The feel of a computer game Combining a game-like character and an intuitive interface gives ITAB tests an advantage in testing populations that have developed an aversion against school math and the static logic of traditional intelligence tests. ITAB tests © CogniMetrics, Inc., 2006

11 How do ITAB tests measure PKL aptitude? The tests provide an interactive task environment in which the individual has to achieve a goal. The tests measure: how feedback is incorporated into follow-up actions how quickly this leads to a more or less efficient procedure ITAB tests © CogniMetrics, Inc., 2006

12 Innovative features 1.ITAB tests provide an (interactive) task environment.task environment 2.Actions of individuals are not scored as singleton answers to distinct problems, but analyzed as sequence patterns. sequence patterns ====== 3.The test report is organized according to an empirically tested structural equations model.test report ITAB tests © CogniMetrics, Inc., 2006 CONTINUE

13 ITAB: TEST DATA Each ITAB test provides an interactive task- environment. An examinee action (user action) changes the environment (system action) and the examinee receives feedback about the new state of the task-environment (system output). The diagnostic components of the ITAB tests measure these changes per user step and analyses: sequential aspects of the user actions The informational content of each new system state ITAB tests © CogniMetrics, Inc., 2006

14 ITAB: TEST REPORT The diagnostic components of the ITAB tests organize the many measurements into three scores that are intuitively accessible. The individual test reports provide these scores for prediction purposes as well as detailed analysis of test performance that may help understanding and improving it.

24 Interactive Task Environment: Complete interactivity is achieved by creating an internal representation of the task-environment. Artificial Intelligence technology is used to compute the intelligence of each step. RETURN © CogniMetrics, Inc., 2006 ITAB tests

25 Analysis of behavior sequences Unlike traditional tests, ITAB tests do not consists of items with a standard set of responses. The individual is free to act within the task-environment. The individual must produce a sequence of actions to achieve a goal, while using the feedback provided by the task-environment. Performance assessment is based on analysis of these action sequences.
