These magdalenian sites show clear variations in spatial, quantitative and qualitative aspects of the find material.
To test the role of purely spatial global properties, the luminance distribution in each image was subjected to a spatial-frequency analysis.
Limited almost exclusively to problems of spatial perception, that analysis gives short shrift to even the most fundamental issues of psychological or physiological import.
A slow falling time of compressed pulse was observed due to the reduced intensity at the wings of the spatial profile.
However, co-occurrence patterns on burned sites were random, indicating absence of competition at fine spatial scales due to differential habitat use within the burned landscape.
