新奇寻求被认为是适应性的，婴儿期的新奇偏好可以预测成年后的认知表现。然而，7个月大的奥尔兹在寻找隐藏的物体时更喜欢熟悉的刺激，而不是新颖的刺激，与他们对可见物体的强烈新奇偏好形成对比（Shinskey & Munakata，2005）。根据对物体知识的分级表征观点，婴儿通过经验逐渐发展出更强的物体表征，从而可以更好地保持对熟悉物体的表征，支持比对新物体更大的搜索。随着年龄的进一步发展，物体表征应该得到加强，以便让年龄较大的婴儿从熟悉转向对隐藏物体的新奇偏好。目前的研究通过向24名11个月奥尔兹展示新颖和熟悉的物体来验证这一预测，这些物体有时可见，有时隐藏。与7个月奥尔兹不同，11个月奥尔兹对可见和隐藏的物体都表现出新奇的偏好。这种对隐藏物体从熟悉到新奇偏好的发展转变与婴儿在几个月前对可感知刺激表现出的转变相似，但这两种转变可能反映了不同的潜在机制。目前的研究结果表明，在适应性发展的对象表征和相关的认知过程的变化和连续性。
Novelty seeking is viewed as adaptive, and novelty preferences in infancy predict cognitive performance into adulthood. Yet 7‐month‐olds prefer familiar stimuli to novel ones when searching for hidden objects, in contrast to their strong novelty preferences with visible objects (Shinskey & Munakata, 2005). According to a graded representations perspective on object knowledge, infants gradually develop stronger object representations through experience, such that representations of familiar objects can be better maintained, supporting greater search than with novel objects. Object representations should strengthen with further development to allow older infants to shift from familiarity to novelty preferences with hidden objects. The current study tested this prediction by presenting 24 11‐month‐olds with novel and familiar objects that were sometimes visible and sometimes hidden. Unlike 7‐month‐olds, 11‐month‐olds showed novelty preferences with both visible and hidden objects. This developmental shift from familiarity to novelty preference with hidden objects parallels one that infants show months earlier with perceptible stimuli, but the two transitions may reflect different underlying mechanisms. The current findings suggest both change and continuity in the adaptive development of object representations and associated cognitive processes.
