国际最新研究：笑声或引发倭黑猩猩情感共鸣并影响行为

Core Insights - A study published in the journal "Scientific Reports" indicates that bonobos (Pan paniscus) are more likely to approach objects that may or may not contain rewards when they hear laughter, suggesting that laughter may evoke emotional resonance in bonobos and influence their behavior [1][3][7] Group 1: Research Findings - The study monitored four trained bonobos, revealing that they interact with or ignore boxes based on whether they might contain food, indicating that positive sounds can affect their foraging and searching behavior [3][5] - The research involved four bonobos of varying ages and genders, assessing their cognitive abilities through interactions with a black box (with food reward) and a white box (empty), where they were trained to reject the white box [5][7] - During the tests, bonobos approached the black box 93% of the time and only 1% of the time approached the white box, with a higher likelihood of checking gray boxes when laughter was played, showing a 3.4 times increase in approaching gray boxes compared to control sound conditions [5][7] Group 2: Implications and Future Research - The authors suggest that laughter may trigger emotional resonance in bonobos, making them more inclined to approach ambiguous stimuli [7] - The researchers recommend that future studies should focus on the role of laughter in the evolution of social connections among primates, given the small sample size of this study [7]
