Education has numerous contributions to society; however, the occurrence of aggressive behaviors can be a challenge for it to be successful in its goals. Therefore, this study proposes to carry out a conceptual analysis of the aggressive behaviors of students in the classroom, from their forms of use in studies of the behavioral-analytic literature. This research was methodologically divided into specification and selection of sources, investigation, and treatment of information. From these steps, four articles were selected, and four categories of analysis were constructed. The main findings were variables of the school environment as antecedent events to the aggressive behavior of students, such as the production of aversive demands for students and the teacher's behavior. Regarding the class of responses, more topographies of physical aggression were found, directed both at the person and at others or even other places and/or objects. As for the consequences and the functions, it is mentioned the escape of demands and interruption of activities (negative reinforcement) and the teachers' obtaining attention from the students (positive reinforcement). Finally, it is concluded that revisiting the scientific literature in the field of behavior analysis can be relevant to generate new questions about the theme of aggressive behavior of students in the school context, helping their understanding.

Efeitos de choques incontroláveis sobre comportamento agressivo do peixe de briga do Sião (Betta splendens)

The previous exposure to uncontrollable aversive events may produce not only difficulty in learning new responses, widely reported in studies of learned helplessness, but may also affect unlearned behavior such as aggressive behavior. The aim of this study was to verify the effects of uncontrollable shocks on the aggressive behavior of Siamese fighting fish (Betta splendens). It was utilized 18 domesticated Betta splendens divided into three groups with 6 animals each, a group that did not receive shocks (Control – CTRL), one that received Controllable Shocks (CHC group) and one that received uncontrollable shocks (CHI group). The apparatus used were an aquarium proper to the observation of aggressive behavior and a shuttlebox for the shock treatment. The procedure was performed in three phases: in the first phase, the aggressive behavior of the animal was registered (baseline) for 5 minutes after 10 minutes of habituation. In the second phase, the animals of the CHC group received 3 controllable shocks of approximately 0.6V with maximum duration of 30s each if the animal did not issue an escape response that consisted in crossing to the opposite side of apparatus, which ceased the shocks; all the animals escaped in three attempts. The animals of the CHI group, in the second phase, received the same amount and duration of shocks that received its equivalent in the CHC group. In the third phase, the test was carried out and the aggressive behavior was registered again, similarly to the baseline. The interval between phases was of 24h approximately. The components of aggressive behavior registered were: display; attack; emerging; resting. These behaviors were measured regarding the latency of the first response, response frequency and duration. Statistical analysis were performed between groups and intragroup; the analysis between groups did not show statistically significant differences, and the intragroup analysis showed significant difference only regarding the latency of the first display response in the test [H(1) = 4.078, p = 0.041] in the CHI group, thought this response decreased in all group. Therefore, this reduction cannot be attributable to the treatment with uncontrollable shocks. Thus, since there were no statistically significant differences between groups nor intragroup for the responses measured, neither before nor after the exposure to uncontrollable shocks, it can be said that, taking into account the experimental conditions of this study, the uncontrollable shocks do not attenuate the aggressive behavior of Betta splendens similarly to what happens with rats and mice when they are exposed to situation of uncontrollability with electric shocks.
