| Research Abstract |
In the present studies, we carried out the following four investigations.
1. Holistic and hierarchical information processing of structure. Geometrical-optical illusion is perceived, when people holistically perceive a figure which has a particular structure, that is, when structural information is holistically processed. Cognition of a gymmetrical-optical illusion is a cognition of a figure or pattern. Based on the transformational structure theory, we proposed how to define and make taxonomic classification of geometrical-optical illusion. In addition, we proposed that information processing of structure of a figure is processed holistically and hierarchically by cognitive system such as human being.
2. Cognition of structure and processing limit of structural information. In this study we used Fraser figure and quasi-Fraser figure. These figures are physically co-circles but perceptually spiral. When a spiral is rotated, we see the spiral expanding or contracting, depending on the direction of rotation. We measured the processing limit of the structural information by investigating this dynamic geometrical-optical illusion.
3. Analytical and synthetic processing of structural information. We investigated the microcognitive process in memorization and immediate recall of random series of digits. The results showed that subjects processed analytically as well as synthetically the structure of series of digits in the their performances.
4. Theoretical derivation of latent structure. We proposed a model to analyze asymmetric matrix of proximity. This model may be applicable to the study of synthetic and analytic processing of structure in cognitive process, since a latent structure is derived from data matrix of stimuli and responses.
