The aims of this research were to evince the cognitive reconstruction of the causal nexus of an atmospheric pollution case. The research was carried out with the contribution of eight participants whose age varied from 14 to 17 years old. The task given to the participants consisted in the solving of a symbolic problem which was simulated in the computer, and which was supposed to be solved within sessions. Data were obtained through systematic observation, clinical inquiry and log files. For the aim of this paper, two subjects considered prototypes were examined, one of them due to his ease and quickness in problem solving and the other one because of his difficulty and lateness. The development of the environmental analysis progress is discussed.
