The speed at which we drink alcohol could be influenced by the shape of the glass, and markings on the glass might help us drink more slowly, according to new research from the University of Bristol, presented today at the British Psychological Society Annual Conference in Liverpool.PhD student David Troy and Dr Angela Attwood from Bristol’s Tobacco and Alcohol Research Group presented the study as part of a symposium on ‘Environmental influences on food and alcohol-related behaviour’.David Troy said: “Excessive alcohol use is a major public health concern and there is a lot of interest in alcohol control strategies.  It is important to determine what environmental factors are contributing to excessive use and how they can be altered to nudge drinkers towards more responsible consumption.”
