Optical illusion from the wrong choice of glass can significantly increase the consumption of alcohol. The results of their experiments with the form of glass published in the journal PLoS ONE British scientists.
Because binge drinking is becoming an increasingly urgent problem of the young generation, and the data of the world health organization suggests that the abuse of alcoholic drinks kills 2.5 million people annually, experimental psychologist Angela, Attwood from the University of Bristol (UK), together with colleagues decided to conduct my research.
Colleagues, Attwood was able to establish that people often do not even suspect how much they drink. Indeed, in normal portions, which use the staff of Queen Margaret University, the percentage of alcohol in 2 times above the standard measures used by the British authorities for the assessment of alcohol consumption in the country. Dividing randomly 160 people in 8 groups, the researchers suggested that the examinee to see the documentary film about the beauty of nature, "squeezed" view 177 or 354 ml dark beer from glasses with straight or curved walls. Volunteers then had to solve several problems in care.
The group that received the glass with curved walls, drank beer for 8 minutes. The group also inherited glasses with straight sides, was required for the absorption of the same amount of beer in 13 minutes. Another experiment has proved that getting a glass, tapering towards the bottom, the subjects were able to correctly estimate the amount of liquid in the vessel. And according to Angela, Attwood, most beer lovers mentally divide the glass in half to measure the rate of drinking in company with this indicator. One of the co-authors of the study Jen Gill believes that the findings of colleagues incorrect, as among the participants of the experiment were not just moderate drinkers, and people who use up to 50 standard drinks of alcohol per day (about 12 liters of beer with an alcohol content of 3.5-4%). While such participants are unlikely to care about the shape of the glass.
