The inhibition of predatory behavior observed during the "prawn-in-the-tube" procedure has been extensively used in studies of cuttlefish learning. The present study examines the effect of age on the conditioning of this response in the cuttlefish, Sepia officinalis. Data show that a significant increase in acquisition performance occurs between 15 and 21 days of age. The retention curves in 8- and 15-day-old cuttlefish show a monotonic memory process, presumably reflecting the presence of only short-term memory. In 21-day-old cuttlefish, there are two distinct processes which could be a labile short-term memory, and a subsequent intermediate memory. These mnesic systems seem to become more effective over the course of post-embryonic development. Moreover, the retention curves obtained in the oldest cuttlefish (30- and 90-day-old) bear a close resemblance to that observed in adults. These behavioral findings will allow further work on the cellular and molecular mechanisms of learning and memory in the cuttlefish.
在“管中虾”实验过程中观察到的捕食行为抑制现象，已被广泛应用于乌贼学习研究。本研究考察了年龄对乌贼（Sepia officinalis）这种反应条件反射的影响。数据表明，在15至21日龄之间，习得表现显著提高。8日龄和15日龄乌贼的保持曲线显示出单调的记忆过程，推测这仅反映了短期记忆的存在。在21日龄的乌贼中，有两个不同的过程，可能是不稳定的短期记忆和随后的中期记忆。这些记忆系统似乎在胚胎后期发育过程中变得更加有效。此外，在最年长的乌贼（30日龄和90日龄）中获得的保持曲线与在成年乌贼中观察到的曲线非常相似。这些行为学发现将有助于进一步研究乌贼学习和记忆的细胞及分子机制。
