In two experiments, we investigated how learners comprehend the functioning of a three-pulley system from a presentation on a computer screen. In the first experiment (N ¼ 62) we tested the effect of static vs. animated presentations on comprehension. In the second experiment (N ¼ 45), we tested the effect of user-control of an animated presentation on(More)
The effectiveness of animations containing two novel forms of animation cueing that target relations between event units rather than individual entities was compared with that of animations containing conventional entity-based cueing or no cues. These relational event unit cues (progressive path and local coordinated cues) were specifically designed to(More)
This experiment examines how, high and low mechanical and spatial abilities, learners understand an animation. Two variables were manipulated: the controllability of the animations and the task type of the learners to study the device. The comprehension test results indicated a positive effect of a fully controllable animation and also a positive effect of(More)
In two experiments we examined how learners understand an animation about a mechanical complex three pulleys system. In the first experiment were tested the animation user-control and the orientation of the attention of the learners. The second experiment tested the potential effect of adding signaling cues like arrows on the comprehension of the mechanical(More)
In humans as well as other animals, displays of body strength such as power postures or deep masculine voices are associated with prevalence in conflicts of interest and facilitated access to resources. We conduct here an ecological and highly critical test of this hypothesis in a domain that, on first thought, would appear to be shielded from such(More)
