研究问题
However, these paradigms offer a procedural advantage over classical or operant conditioning paradigms; they do not rely on external reinforcers (e.g., shocks or food), which may influence regional circuit recruitment and obscure age-dependent learning-related neurobiological changes (; ; ; ; ).
方法
The intrinsic novelty preference that underlies object recognition assays likely has overlap with reinforcement mechanisms engaged when external rewards are presented by the experimenter.；Because testing age was a within-subject factor, we used two distinct object sets in the pre-weanling and adult tests.
核心结论
Novel object recognition (NOR) and location (NOL) tasks capitalize on rodents’ innate novelty preference and have revealed significant corticolimbic contributions to memory that are dependent on both the psychological (e.g., identity versus spatial) and temporal (e.g., short-term versus long-term memory) demands of the task (; ; ; ; ; ; ; ; ; ; ; ).；For example, access to novel objects has the capacity to condition a place preference, suggesting novelty serves as its own internally generated reinforcement signal ().；However, these paradigms offer a procedural advantage over classical or operant conditioning paradigms; they do not rely on external reinforcers (e.g., shocks or food), which may influence regional circuit recruitment and obscure age-dependent learning-related neurobiological changes (; ; ; ; ). ‖ 结论：Recognition tasks already provide a powerful window into cognitive development; realizing their full potential will require treating behavior not as a single outcome measure, but as a rich source of information about the developing brain.

A 级证据分级：A 级（同行评议人体研究）
本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
