The objective of this study was to investigate the emergence of a "mindy" (a unit of mind). The mindy is characterized as an open, organized, discrete, and kinematic mental shape. The study was the sequel to research on the emergence of mental shape (R. Laassonen, 1993). The subjects were 84 students, aged 13 to 16 years and differentiated into age groups, from a comprehensive secondary school. A test battery that involved filling in deleted parts of figures was constructed for variables of former experience, ambiguous information, the croupier process, contour formation, and filling-in. The croupier process is one that separates, sorts, and collects information. The reliability and validity were evaluated, and proved to be reasonable. The velocities of the variables were calculated and the relationships of the variables (cosines) were elaborated with partial correlation coefficients. The results indicated the existence of preparatory and making processes in mindy construction, with the making process being an autonomous one. The study has implications for educational theory construction and practical teaching behavior because the environmental information organization process was the most influential and the making process cannot be affected with interruptions. In addition, there are implications for planning curricula in subject matters, especially the information arrangement aspects emphasized. (Contains five tables and three references.) (Author/SLD)
