摘要行为学和神经生理学研究支持右耳优势（REA）在鸟类和哺乳动物中存在的观点。然而，很少有研究集中在无尾类物种，通常通过发声沟通。研究了峨眉乐蛙（Babina daunchina）对置于被试身后的扬声器发出的6种听觉刺激的定向行为。刺激包括雄性广告呼叫从洞巢内，这已被证明是高度性吸引力（HSA），呼叫从洞外，这是低性吸引力（LSA），尖叫声时，青蛙被蛇攻击，白色噪音，雷声和沉默。对于除尖叫声之外的所有声音刺激，青蛙优先转向右侧。右耳偏好是最强的HSA呼叫。对于尖叫声和雷声刺激，受试者更倾向于远离说话者，而不是转身。这些结果支持的想法，在无尾类，右耳偏好与感知的积极或中性信号，如同种广告呼叫和白色噪音，而左耳偏好与感知的负面信号，如掠夺性攻击。突出显示的文章：右耳优势在无尾两栖类中通过定向任务表现出来，表明生物学意义的差异会引起不同的反应，表明定向受到交配策略和情绪处理的影响。
ABSTRACT Behavioral and neurophysiological studies support the idea that right ear advantage (REA) exists for perception of conspecific vocal signals in birds and mammals. Nevertheless, few studies have focused on anuran species that typically communicate through vocalization. The present study examined the direction and latencies of orientation behaviors in Emei music frogs (Babina daunchina) produced in response to six auditory stimuli emitted by a speaker placed directly behind the subjects. The stimuli included male advertisement calls produced from within burrow nests, which have been shown to be highly sexually attractive (HSA), calls produced from outside burrows, which are of low sexual attractiveness (LSA), screech calls produced when frogs are attacked by snakes, white noise, thunder and silence. For all sound stimuli except the screech, the frogs preferentially turned to the right. Right ear preference was strongest for HSA calls. For the screech and thunder stimuli, there was an increased tendency for subjects to move further from the speaker rather than turning. These results support the idea that in anurans, right ear preference is associated with perception of positive or neutral signals such as the conspecific advertisement call and white noise, while a left ear preference is associated with perception of negative signals such as predatory attack. Highlighted Article: Right ear advantage is demonstrated behaviorally in an anuran through an orientation task, which shows that differences in bio-significance induce variable responses, suggesting orientations are affected by mating strategy and emotion processing.
