It seems that the increase of the number of oversea study tour participants is not caused by the enrollment from the ex-8th-school district. It may be worthwhile to investigate the possible reason to make the marketing or recruiting process more effective and time-saving.
As Keane put it: "the standard production system has a limited working memory that parallels the limitations of human working memory. Thus, by limiting the number of items working memory can hold, the effects of information loss in a cognitive task can be simulated."(p.290, Mark T. Keane, 'production systems', "The Blackwell Dictionary of Cognitive Psychology", 1990, Blackwell Publishers, Oxford, UK) So students' working memory is limited. "(B)y limiting the number of items working memory" hold, they can simulate "the effects of information loss in a cognitive task," or how many points they would lose in a test. In other words, they can examine the limitation of their working memory by doing "cognitive" tasks, each of them with the different number of items.
I have been studying "nonlinear system" for a couple of days with a journal I borrowed from a math teacher. Fractale and complex number seem to be key words. "i" is an imaginary number. If "a" and "b" are real numbers, "a+bi" makes a complex number. An equation with a complex number draws a fractale.
We have a transcendental framework of cognition, or a biological framework of cognition, which is a priori, and an acquired framework of cognition, or a cultural framework of cognition, which is a posteriori.
