Alcohol dependency has been connected to altered brain activity and
cognitive decline. However, data regarding the influence of acute and low-to-moderate
alcohol use on cognition are inconsistent. The aim of the study was to assess
the influence of 0.1-0.25 mg/dm³ of breath alcohol concentration (BrAC) on cognitive
functions such as attention, perception, psychomotor speed and visual-spatial
functions, in 50 young alcohol nondependent adults. We observed a worsening
in focus attention measured with Cross Apparatus following the consumption
of a given dose of alcohol. We also revealed the occurrence of learning effect in
measures of attention and psychomotor speed. However this effect was significantly
weakened in participants who were intoxicated in the first testing. We concluded
that the studied concentration of alcohol may have a negative effect on focused
attention and ability to benefit from previous experience which are crucial for complex
behaviours, such as driving.
Key words: alcohol, attention, reaction time, general perceptual ability, spatial
perception
