The objective of this study was to inquire if tunneling of mind, motivation to novelties, and creative mindies in 4 age groups (13, 14, 15, and 16, years of age) have dynamic relationships. A creative mindy is a new organized mind shape not previously occurring. The subjects were 93 pupils of a secondary comprehensive school. Questionnaires were constructed to measure tunneling and motivation to novelties. A creative mindy test was developed. A coefficient for reliability was developed through the coefficients of determination and nondetermination. Validity was examined calculating scalar products of the items between the age groups divided by the maximum scalar product. The reliability coefficients proved to be rather satisfactory (the mode was 0.80). The validity coefficients were satisfactory (the modes were 0.90). The item scores because of high correlations were added to a sum score and a usual statistical classification procedure was applied to the quantification of the variables. Matrix products were used to break the symmetries between the variables. The hypothesis was not supported. The results indicate that no sole variable exists. The variables acted as a dependent variable in turn and formed eccentric feedback loops in moving from mutual stabilization to oscillation. Age differences in tunneling thinking are discussed, and implications for teaching are reviewed. (Contains five tables and seven references.) (Author/SLD)
