Despite their excellent auditory capacities, dogs do not attend to differences between words that differ only in one phoneme (e.g., "dog" vs "dig"), according to a new study by Hungarian researchers of the Eötvös Loránd University, Budapest (ELTE). In the study, they measured brain activity with non-invasive electroencephalography (EEG) on conscious dogs. This might be a reason why the number of words dogs learn to recognize typically remains low throughout their life. The study is published in Royal Society Open Science.
