Abstract

Cognitive models of habituation and dishabituation postulate that the latter is attributable to the perturbation of the model of the repeated stimulation stored in short-term memory (STM) by the occurrence of a new stimulus, called dishabituator. However, although both behavioral phenomena depend on STM, previous studies in Aplysia have found that dishabituation seems to require further steps of development of the STM system to emerge. Here, we addressed whether this is a universal condition for the appearance of the 2 forms of learning, namely whether dishabituation must necessarily follow habituation. To this aim, we studied habituation and dishabituation of the freezing response to a sudden acoustic stimulation in newly hatched chicks (1 day old vs. 3 days old). The results showed that in chicks, dishabituation was fully present a few hours after hatching, a pattern of results indicating that, in this precocial avian species, habituation and dishabituation share the same developmental trajectory and the underlying STM mechanisms are simultaneously operative soon after birth.

新生雏鸡冻结反应适应与不适应的短期记忆。
习惯化和不习惯化的认知模型假设后者是由于存储在短期记忆(STM)中的重复刺激模型受到新刺激(称为不习惯者)的扰动。然而,尽管这两种行为现象都依赖于STM,但先前在澳大利亚的研究发现,不适应似乎需要STM系统的进一步发展才能出现。在这里,我们讨论了这是否是两种学习形式出现的普遍条件,也就是说,不习惯化是否一定要遵循习惯化。为此,我们研究了新孵化的小鸡(1日龄和3日龄)对突然声刺激的冻结反应的习惯化和不习惯化。结果表明,雏鸟在孵化后数小时内就完全脱臼了,这一结果表明,在这个早熟鸟类物种中,适应和脱臼具有相同的发育轨迹,潜在的STM机制在出生后不久就同时起作用。(PsycINFO数据库记录(c) 2018 APA,版权所有)。
