[Attentions, sensumotoric coordination, and angular acceleration threshold under the influence of small doses of alcohol in relation to aspects of personality (author's transl)].

In a parallel cross-over design 22 male students were examined with 0,6 g alcohol per kg of body weight (0,5 o/oo). The dependent variables were attention, sensumotoric coordination angular acceleration threshold, and mood. A number of personality trait factors (FPI, MPI, habit of alcohol and tobacco consumption, body measures) and state factors (subjective state, psychophysiological state) were also measured, others were helf constant (age, sec, intelligence, standardisized breakfest, duration of drinking time, day time, week time). The accelerated concentration of blood alcohol was connected with neuroticism and subjective bad state on day of examination. The accelerated elimination of blood alcohol varried with bad subjective state. Attention, and sensumotoric coordination were significantly (by a BAC of 0,42 o/oo) diminished and the sensitivity of angular acceleration threshold was strongly (by a BAC of 0,30, 0,44, 0,38 and 0,21 o/oo) diminished, connected with a general brightening of mood. Certain personality traits and states may diminish performances with those slight doses of alcohol.
