Hubbard TL (2019) Momentum-like effects and the dynamics of perception, cognition, and action. In future experiments, it is necessary to personalize the intensity and duration of subliminal stimulation according to the definition of sensory threshold, so as to enhance its effect. The research direction of this experiment is worth further exploration. Subliminal stimulation designed in this paper has no obvious effect on perceptual judgment, but from the mean of the absolute value of perceptual error, it can be seen that judgment bias in the comprehensive intervention group of “audiovisual subliminal stimulation” has a downward trend, which shows that subliminal stimulation can improve the accuracy of attention cognition to a very small extent. Conclusions: With the increase of task difficulty, the error of perceptual judgment increases, that is, the accuracy decreases. Results: The main effect of task difficulty on perception was significant ( p 0.05) the interaction between task difficulty and subliminal stimulation was not significant ( p > 0.05). In order to avoid the effect of experimental sequence, the order of subjects participating in the experiment was balanced in advance according to the independent variable of the type of subliminal stimulation. The three levels of subliminal stimulation are as follows: “no subliminal stimulus”, which can be regarded as a control group, “auditory subliminal stimulus” and “audiovisual subliminal stimulus”. When the number of pentagram stars to be judged was 5–9, it was of low difficulty correspondingly, 10–14 was of medium task difficulty, and 15–19 was of high task difficulty. Task difficulty and subliminal stimulation are the two independent variables, each of which contains three levels. Two factors mixed design was used in this experiment. The experimental task was to determine the number of red pentagram stars presented on the computer screen quickly and accurately. The experimental program was compiled by E-Prime software on the basis of the paradigm of attention span. Methods: 24 college students were recruited to participate in the experiment. Objective: To investigate the effect of task difficulty and dual channel subliminal stimulation on people’s attention perception.
