Abstract
In recent twenty years dogs have become model subjects of comparing studies.These experiments show us that specific cognitive skills have developed during their domestication as an adaptation to anthropomorphic environment. For example dogs can follow human gaze and understand gestures.
An important topic of today researches is perception of verbal communication. Knowledge from this area would help to discover more from evolution processes which formed human language.
Last studies have proven dogs can distinguish a new object by a fast mapping. But when distinguishing more objects, dogs had problems.
The present study is focused on the experimental verification of dogs' ability to distinguish two object names through rapid mapping and the importance of human communication channels in word perception.
