The effect of early experience on the growth and ontogeny of memory in cuttlefish (Sepia officinalis) was studied using an associative learning protocol. Five groups of cuttlefish were reared in different conditions (standard conditions, SC; impoverished conditions, IC; enriched conditions, EC; impoverished then enriched conditions, I/EC; enriched then impoverished conditions, E/IC) from birth to the 3rd month of postembryonic life. Acquisition and retention of the learning task were assessed at 1 and 3 months. Growth was slower and maturation of memory abilities occurred later in cuttlefish from Group IC than in cuttlefish from Group EC, with the maturation rate of memory in cuttlefish from Group SC intermediate between these two groups. Retention performances of cuttlefish from Groups I/EC and E/IC indicated that the environment of rearing during the 2nd and/or 3rd months of life was crucial for the development of memory.
利用一种联想学习方案，研究了早期经历对乌贼（Sepia officinalis）记忆生长和个体发育的影响。五组乌贼从出生到胚后生活的第3个月在不同条件下饲养（标准条件，SC；贫乏条件，IC；丰富条件，EC；先贫乏后丰富条件，I/EC；先丰富后贫乏条件，E/IC）。在1个月和3个月时评估学习任务的习得和保持情况。与EC组乌贼相比，IC组乌贼的生长较慢，记忆能力成熟较晚，SC组乌贼的记忆成熟率介于这两组之间。I/EC组和E/IC组乌贼的保持表现表明，生命第2个月和/或第3个月的饲养环境对记忆发展至关重要。
