This study examines decision-making behaviors in humans playing the game of rock-paper-scissors, and establishes a negative phototaxis model in pill bugs using a T-maze to explore behavioral preferences and decision dependence. Our results indicate a higher probability of choosing "rock," and that as the time interval decreases, the probability of choosing "scissors" increases while the probability of choosing "rock" decreases. Furthermore, a negative correlation of decision experience dependence was observed, particularly in the "slow-choice" group, suggesting that a shorter inter-response time reduces conscious deliberation and weakens the negative correlation of decision experience dependence. On the other hand, pill bugs exhibited a persistent negative phototactic choice direction even after the aversive stimulus had ceased, indicating a habitual response. After multiple choices of walking direction, pill bugs showed a positive correlation with their previous choice. Following a negative phototactic stimulus, this phenomenon initially disappeared and then reappeared. When the direction of the negative phototactic stimulus was reversed, the original phototactic behavior disappeared, presumably due to the interference of habitual direction choice with the negative phototactic choice.
