Effect of experience of occlusion events on the domestic chick's strategy for locating a concealed imprinting object

Domestic chicks were tested with a task involving an imprinting object. It was proposed that the chicks would search behind whichever hiding site the object was moving towards before occlusion.A sensitive period of learning about occlusion events leading to qualitative changes in the strategy for locating concealed objects, was also predicted.It is concluded that orientation towards the concealed object is based on previous spatial location alone.
