摘要
许多鱼类通过将新的刺激与受损表皮组织释放的损伤释放的化学线索配对来学习识别捕食风险的相关性。在这里,斑马鱼习惯于将捕食风险与三个音调的听觉刺激C5 (523.25 Hz) + E5 (659.25 Hz) + G5 (783.99 Hz)联系起来,然后测试对一个音调(C)的反应,在警报提示和C + E + G条件下,斑马鱼对完整的C + E + G刺激或原始组合的部分表征(C + G)的反应明显强于对原始C + E + G条件刺激的单一元素(C)的反应。对单一成分缺乏反应可能是未能识别刺激或将部分成分解释为低风险指标。
Ring a bell? Variable recognition of a multicomponent auditory stimulus associated with predation risk by zebrafish responding to full and partial matches
Many fishes learn to recognize correlates of predation risk by pairing novel stimuli with injury-released chemical cues released from damaged epidermal tissues. Here, zebrafish were conditioned to associate predation risk with a three-note auditory stimulus C5 (523.25 Hz) + E5 (659.25 Hz) + G5 (783.99 Hz), then tested for responses to either only one tone (C), two of the components (C + G) or the full three-note chord (C + E + G). Zebrafish conditioned with alarm cues and C + E + G responded significantly more intensely to the full C + E + G stimulus or to partial representation of the original mix (C + G) than they did to the single element (C) of the original C + E + G conditioning stimulus. The lack of a response to the single component alone may be a failure to recognize the stimulus or an interpretation that the partial component is an indicator of low risk.
期刊介绍:
Behaviour is interested in all aspects of animal (including human) behaviour, from ecology and physiology to learning, cognition, and neuroscience. Evolutionary approaches, which concern themselves with the advantages of behaviour or capacities for the organism and its reproduction, receive much attention both at a theoretical level and as it relates to specific behavior.
