power for the first time in national history. The students at that time showed their disagreement with the prevailing political and social system and strongly supported the workers' movement. The Student Federation of the University of Chile, which was relatively new, was composed mainly of students of the Pedagogical Institute among which Rudecindo Ortega, José Domingo Gómez Rojas, Pedro León Loyola, Pablo de Rokha, Juan Gómez Millas (who would end disappointed) of the left and socialism, years later would form the Nationalist Union Party of Chile, a fascist movement) and above all, Eugenio González Rojas, philosophy student who came to preside over the FECH between 1922 and 1923 and was Minister of Education of the Republic Socialist of Chile (this former student also founded the Federation of Secondary Students of Santiago during his stay at the National General Institute José Miguel Carrera). Years later, González travels to Venezuela to create the Pedagogical Institute of Caracas. Upon returning he is appointed Director of the Pedagogical and later Rector of the University of Chile Pioneers in Psychological Research With the twentieth century, Experimental Psychology began in Chile. This had a magnificent boom thanks to professors Guillermo Mann and J.E. Schnider who created the Laboratory of Experimental Psychology, which inaugurated the experimental movement in the country. Although, since 1889 both professors were teaching psychology, it was not until 1908 that Mann was appointed to buy modern instruments and bibliographical material in Europe, establishing in a solid manner the laboratory that aimed to have the characteristics that Wilhelm Wundt used in his University of Leipzig. This would be the first psychology laboratory in a Chilean university institution21 and Wundt himself would have oriented the two teachers to the selection of instruments. While most of the instruments came from Leipzig, there was also a considerable amount of material purchased in Berlin, Paris and Milan. Despite the good performance of this initiative, the lack of state funding (it stopped being subsidized in 1917) meant its early closure. Today, part of the laboratory survives in the Department of Psychology of the current Faculty of Social Sciences of the University of Chile. About these Guillermo Mann declared in a report to the Rector Valentín Letelier: The office of the instruments destined for psychological research can not be other than that of fixing of an exact and measurable physical conditions relations with the psychological processes that are being studied
