My interests are in the information processing underling a wide range of cognitive phenomena. I am particularly interested in high-level cognition; my research encompasses visual-spatial abilities and mental imagery, decision making, ageing, and knowledge acquisition & expertise. My work includes (in addition to basic academic research) applied real world applications in a variety of domains, including biometrics, decision making, training, and cognitive technologies. In addition to cognitive experiments with a variety of different populations, my work relies on computer simulations and neuroscience research. I use computer simulations to construct models of cognition, constrained by current neuroscientific knowledge. I am also interested in the foundations of cognitive neuroscience, philosophy of the mind, and how cognitive research and philosophical questions interrelate. Email: i.dror@ucl.ac.uk

Dror, Itiel E. and Harnad, Stevan (2008): Offloading cognition onto cognitive technology. In: (ed.). "Cognition Distributed: How Cognitive Technology Extends Our Minds". Amsterdam: John Benjamins Publishingpp. 1-23

“"Cognizing" (e.g., thinking, understanding, and knowing) is a mental state. Systems without mental states, such as cognitive technology, can sometimes contribute to human cognition, but that does not make them cognizers. Cognizers can offload some of their cognitive functions onto cognitive technology, thereby extending their performance capacity beyond the limits of their own brain power. Language itself is a form of cognitive technology that allows cognizers to offload some of their cognitive functions onto the brains of other cognizers. Language also extends cognizers' individual and joint performance powers, distributing the load through interactive and collaborative cognition. Reading, writing, print, telecommunications and computing further extend cognizers' capacities. And now the web, with its network of cognizers, digital databases and software agents, all accessible anytime, anywhere, has become our 'Cognitive Commons,' in which distributed cognizers and cognitive technology can interoperate globally with a speed, scope and degree of interactivity inconceivable through local individual cognition alone. And as with language, the cognitive tool par excellence, such technological changes are not merely instrumental and quantitative: they can have profound effects on how we think and encode information, on how we communicate with one another, on our mental states, and on our very nature. ”

Dror, Itiel E. (1992): Visual Mental Rotation: Different Processes Used by Pilots. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 1368-1372.

“Air Force pilots and control subjects were tested on a visual "mental rotation" task. Nine of the 16 pilots, as well as all of the 16 control subjects, required more time to rotate greater angular distances. The performance of the other 7 pilots was unique: their response time did not increase with greater angular rotations. The results suggest that visual mental rotation can be accomplished by at least two different processes. One process involves incremental object rotations in a multi-step mapping -- like an actual physical rotation of an object -- going through intermediate stages. This process requires more time to rotate greater angular distances. The other process involves direct translation in a single-step mapping. In this process, the starting position transforms into the final position in one mapping without any intermediate steps, and thus does not require more time to rotate greater angular rotation. The lack of intermediate stages, which may allow small perturbations in location to be corrected, affects the accuracy of this process; this is particularly apparent when more complex stimuli are rotated. The pilots who did not show incremental rotation effects had different and distinct error patterns, their errors increased when rotating the more complex stimuli.”
