Sentimental object attachment is a phenomenon that begins early in childhood. It is widely theorised that children develop emotional attachment to specific objects as a maternal substitute which varies across cultures and socioeconomic conditions. While the need for these objects should diminish as the child becomes more independent, there is a growing body of work showing that object attachment may persist into adulthood. The reasons for this sustainment are not known but childhood object attachment is associated with a bias for unique individuals which subsequently influences preferences for authentic objects in adulthood.

依恋对象行为的起源与发展

多愁善感的客体依恋是一种始于儿童时期的现象。广泛的理论认为，儿童会对特定物体产生情感依恋，作为母亲的替代品，这种依恋因文化和社会经济条件而异。虽然随着孩子变得更加独立，对这些物体的需求应该会减少，但越来越多的工作表明，物体依恋可能会持续到成年。这种维持的原因尚不清楚，但童年的客体依恋与对独特个体的偏见有关，这随后会影响成年后对真实客体的偏好。
