行为人在过失心理结构支配下所实施的犯罪，是过失犯罪。在疏忽大意过失中，行为人对危害结果既无认识也无意识，但其行为仍是其意志支配下的行为，司法实践对此要解决的核心问题是如何认定行为人的疏忽大意和如何确定应当预见的内容。过于自信的过失是有认识的过失，即行为人对结果的可能发生有认识，但这种认识不具备确定性，从而与间接故意区别开来。 The crime committed by the perpetrator at the merits of the psychological structure of negligence is a crime of negligence. In the negligent negligence, the perpetrator has neither cognition nor consciousness about the result of the harm, but its behavior is still the action under its will. The core problem to be solved by the judicial practice is how to identify the negligence of the perpetrator and how to determine Predicted content. Too self-confident negligence is the fault of cognition, that is, the perpetrator has cognition of the possible occurrence of the result, but this kind of understanding has no certainty and thus is deliberately separated from the indirect.
