| The figure recognition was an active cognition process, while sampling was the first actual stage in the cognition process. The processing stratage had great effects both on the quality and on the speed of information processing. This research was focused on the sampling strategies was investigated in 3 dimensions, which were: (a) the features which were sampled in the cognition process; (b) the order in which the features are sampled; (c) the mental resources distribution when the features were sampled.6 experiments were conducted as follows:(1) Feature-sampling of 3-dimension gemetric figures.(2) Parameter-measuring of 3-dimension geometric figures.(3) Sampling order and mental resource distribution during the sampling processing of the 3-dimension figures.(4) Feature-sampling of facial figures.(5) Parameter-measuring of facial figures.(6) Sampling order and mental resource distribution during the sampling processing of the facial figures.The results showed:(l)The features sampled from both the 3-dimension geometric figures and the facial figures both could be classified into 3 catalogues: (a) basic sampling features; (b) supplement sampling features; (c) unique sampling features.respectively.(2)For the 3-dimension geometric figures sampling, the first sampling-position was most likely located at the outline parts of the figures, and rarely at the center of gravity of the figures. For the facial figures sampling, the first sampling-position was most likely located at the hair part and the outline parts of the figures, rarely at the corners of the mouth and face cheek.The tendency of first sampling-position was affected by the degree of the task-difficultibility. The lower degree of the task-difficultibility was, the more stable and more concentrate the first smpling-position would located at. But , in most cases, the first sampling-position had no significant effects on the figures recognition performance.(3)The sampling order of both 3-dimension geometric figures and facial figures were arranged by the degree of the difference among the sampled-features.the sampling-features with higher degree of the such difference would be prior to those with lower degree in sampling order.(4)The distribution of mental resource in the sampling processing was affected by the degree of the difference of the sampled-features. The sampled-features with higher degree of such difference would be assigned more mental resource than those with lower degree.(5)By optimally assigning the mentals resource, the figures recognition performance could be improved in some degree. |
