Earlier attempts to classically condition sea anemones have yielded inconclusive results. Using light as CS and shock as US, conditioning as distinguished from sensitization and pseudoconditioning was demonstrated in anemones. Procedural controls included substitution of light alone, shock alone, and random light and shock in place of paired light-shock trials. Responses measured were electrical output and folding of the oral disc. The conditioned response was distinguished from the unconditioned response to light and the unconditioned response to shock in terms of response latency of both electrical and behavioral measures.
早期对海葵进行经典条件作用的尝试得出了不确定的结果。以光作为条件刺激（CS），电击作为非条件刺激（US），在海葵中证明了条件作用与敏感化和假性条件作用的区别。程序控制包括单独使用光、单独使用电击以及用随机的光和电击代替配对的光-电击试验。测量的反应是电输出和口盘的折叠。在电和行为测量的反应潜伏期方面，条件反应与对光的非条件反应以及对电击的非条件反应有所不同。
