The main objective of this work is to investigate the etiology of errors in Trigonometric Functions tasks, following the hierarchy of Aline Robert's Knowledge Levels, drawing correlations of this etiology with the Levels of Selective Attention (NAS) required in each one of NFC, thus creating typologies about these errors. Exploratory and experimental research was permeated by the theoretical assumptions of Michèle Artigue's Classical Teaching Engineering (EDC), resulting in a Didactic Sequence (SD) based on theoretical constructs of Neuroscience and Cognitive Psychology. In this regard, some lenses of theorists of these segments were studied, studying some of the characteristics of the attention, their classifications and the cerebral areas involved, emphasizing Bottom up and Top down processes for the creation of the Lapse Matrix (ML) that was made to from the typology of errors found in the literature. It also discusses the anthropological theory of the Didactic (TAD), advocated by Yves Chevallard, to understand the functioning of the relations between subject and object within an institution, where the praxeological organization and the notions of ostensible and not ostensible object, which are fundamental to understand how the students use techniques to solve the Tasks, also discussed by other perspectives, found in other researches related to the same theme. A second year class from Professor José Quintela Cavalcanti State School, located in the municipality of Arapiraca, Alagoas, participated in the research. SD was divided into three moments, applying the diagnostic protocols (PD), analyzing the students' responses and studying possible persistence of the lapses, already properly categorized and in each moment there will be a debate about them. Tasks of Trigonometric Functions were elaborated within the hierarchy proposed in the NFC. The data collection instruments consist of field diary and analysis of the tests performed during SD. The results showed that the lapses sifted appear depending on the ostensible manipulated objects and the non-ostensive objects evoked and some may be antagonistic to each other, in addition to providing other paths of research.
