Which characteristic is associated with high doses of minor tranquilizers?

High doses of minor tranquilizers, which are often prescribed for anxiety and related conditions, are associated with sedation and impairment of motor functions. The pharmacological action of these medications leads to central nervous system depression, resulting in symptoms such as stupor and loss of coordination. This effect can manifest as drowsiness, lethargy, and an inability to perform tasks that require physical coordination or mental alertness.

In contrast, the other characteristics listed do not align with the effects of high doses of minor tranquilizers. Increased coordination, high energy levels, and enhanced social interaction are not typically observed at such doses, as the primary action of these medications is to calm the nervous system rather than stimulate it. Thus, the correct association with high doses of minor tranquilizers is indeed stupor and loss of coordination.
