Transitional objects

Image: Wikipedia

Today, I finally found what I have been looking for - a scientific term for the concept of emotionally "charged" objects and toys. Wikipedia says:

Donald Woods Winnicott (1896-1971) introduced the concepts of transitional objects and transitional experience in reference to a particular developmental sequence. With ‘transition’ Winnicott means an intermediate developmental phase between the psychic and external reality. In this ‘transitional space’ we can find the ‘transitional object’.

I have found a number of interesting books and papers on the topic:
