%X One of the more debated issues regarding training simulators is their validity for transfer of skills to sensory environments that differ from the simulator. In two experiments, the advantages of three-dimensional (3D) and collocated (Col) visual displays were evaluated in a realistic and complex visuomotor task. The two factors were evaluated independently, comparing Col-2D with dislocated-2D (experiment 1) and with Col-3D (experiment 2). As expected, in both cases the more immersive presentation condition facilitated better performance. Furthermore, improvement following training in the more immersive condition carried over to the following less immersive condition but there was no carry over in the opposing order of presentation. This is taken as an indication for the differential development of skills conditioned by the level of immersiveness of the training environment. This further suggests that learning of complex realistic tasks is not carried over from less immersive simulator to the complex sensory environment of reality, due to the large gap in sensory patterns. 1. Introduction Virtual environments of various levels of immersiveness are widely used for training. One of the more debated issues regarding training simulators is their validity for transfer of skills to sensory environments that differ from the simulator. The question of validity is composed of two underlying questions: what is the quality of learning using training simulators, and what is the quality of transfer of manual skills from a training simulator to real life tasks. The first relates to the characteristics of the simulator¡ªwhether it provides the sensory cues needed for optimal learning. The second is especially crucial: it is the newly acquired skills exported to new, less or more immersive sensory environments? For instance does training on surgical incisions in ¡°Flatandia¡± type of world [1], a two-dimensional screen without touch, carry over to space-land (ibid), a 3-dimensional virtual world with haptics? The first being evolutionary alien, while the second is friendly and well experienced. The skills for successful performance in each do not overlap. An additional level of learning and transfer difficulty is added when haptics is dislocated from the visual cues. For instance, if playing virtual tennis, you feel the ball hitting your arm, but see the hit on your iphone. Dislocation and flatness change drastically the sensory input in the active exploration cycle [2]. The active exploration cycle refers to the continuous cyclic process that involves sensory scanning,
