Introduction Perceived benefits are considered one of the significant factors affecting an individual’s decision-making process. Our study aimed to explore the influence mechanism of perceived benefits in the decision-making process of unsafe behaviors. Methods Our study used the “One Stimulus-Two Key Choice (S-K1/K2)” paradigm to conduct an EEG experiment. Participants ( N = 18) made decisions in risky scenarios under high perceived benefits (HPB), low perceived benefits (LPB), and control conditions (CC). Time domain analysis and time-frequency analysis were applied to the recorded EEG data to extract ERPs (event-related potentials) and EROs (event-related oscillations), which include the P3 component, theta oscillations, alpha oscillations, and beta oscillations. Results Under the HPB condition, the theta power in the central ( p = 0.016*) and occipital regions ( p = 0.006**) was significantly decreased compared to the CC. Similarly, the alpha power in the frontal ( p = 0.022*), central ( p = 0.037*), and occipital regions ( p = 0.014*) was significantly reduced compared to the CC. Under the LPB condition, theta power in the frontal ( p = 0.026*), central ( p = 0.028*), and occipital regions ( p = 0.010*) was significantly reduced compared to the CC. Conversely, alpha power in the frontal ( p = 0.009**), central ( p = 0.012*), and occipital regions ( p = 0.040*) was significantly increased compared to the HPB condition. Discussion The high perceived benefits may reduce ind...
