Rehearsal versus map study as preparation for a flight navigation exercise.

A flight simulator and a computer-generated depiction of an environment with both natural and cultural features were used to teach and test navigation knowledge. Conditions of guided rehearsal, unguided rehearsal, and map study were used to familiarize participants with the navigation environment. A subsequent route-following test of navigation knowledge in the simulated environment showed that unguided rehearsal was better than map study or guided rehearsal for the development of route knowledge. In addition, a pointing task revealed that unguided mission rehearsal was as good as map study for the development of survey knowledge. Actual or potential applications of this research include the use of simulator-based mission rehearsal for military flight operations.

Quasi-transfer as a predictor of transfer from simulator to airplane.

Simulators have emerged as important components of flight-training programs. Nevertheless, the development of design principles that can maximize training transfer and cost-benefit trade-offs are not well established. The most significant challenge to research that would bear on simulator design principles is the difficulty and expense of flight transfer experiments. This difficulty and expense can be reduced by the use of an insimulator transfer design, designated here as a quasi-transfer study, in which transfer is to a high-fidelity configuration of a simulator. Of primary concern for such studies is whether the implied assumption of correspondence between quasi-transfer and transfer effects is well founded. In this article, we review evidence that bears on this issue. The evidence is not entirely supportive but does indicate some correspondence between quasi-transfer and transfer.

An informational perspective on skill transfer in human-machine systems.

Differentiation of perceptual invariants is proposed as a theoretical approach to explain skill transfer for control at the human-machine interface. I propose that sensitivity to perceptual invariants is enhanced during learning and that this sensitivity forms the basis for transfer of skill from one task to another. The hypothesis implies that detection and discrimination of critical features, patterns, and dimension of difference are important for learning and for transfer. This account goes beyond other similarity conceptions of transfer. To the extent that those conceptions are specific, they cannot account for effects in which performance is better following training on tasks that are less rather than more similar to the criterion task. In essence, this is a theory about the central role of low-dimensional informational patterns for control of behavior within a high-dimensional environment, and about the adjustment of an actor's sensitivity to changes in those low-dimensional patterns.

Explicit and implicit horizons for simulated landing approaches.

In a flight simulator experienced pilots flew landing approaches to a representation of an airport scene in which various sources of information had been distorted or removed. Reasonably accurate approaches could be made to a scene that contained only an aimpoint and a horizon. The addition of a runway outline did not enhance accuracy or stability, which lent credence to the hypothesis that the invariant angle between horizon and aimpoint can support glide slope control. Explicit distortion of this angle by simulation of up-sloping or down-sloping terrain beyond the runway had predictable effects on glide slope control. Implicit specification of a veridical horizon with texture lines parallel to the runway centerline weakened the effect of distortions in the explicit horizon. Thus both explicit and implicit specifications of the horizon contribute to perception of the glide slope angle. Implications of these results for the design of visual scenes for flight simulation are discussed.
