The audio presented to the subjects was degraded in order to avoid ceiling effects, using a 3-channel noise excited vocoder shannon et al. [40].
Spatial analyses based on average distances, weighted overlay analysis and involving the digital terrain model of the general area have been performed in order to compare ceiling distributions based on decoration similarities and the historical road network.
The signal-to-noise ratios (0.33 in Experiment 1, 0.25 in Experiments 2 and 3) used in the reported Experiments were selected in order to avoid ceiling and floor effects for sensitivity judgments.
We purposefully made the task relatively difficult in order to avoid ceiling performance.
We expanded the original list in order to avoid ceiling effects (italic printed nouns).
In order to avoid ceiling effects, the original version of 15 semantically unrelated nouns was expanded to 25, controlling for word frequency (on the basis of a comprehensive search using the "google" search system) [ 27] and categories.
