Social skills
Social skills were used to communicate with others daily in a variety of ways including verbal, non-verbal, written and visual.
While celebrating the christening of the new quantum slipstream drive aboard USS Voyager in 2375, Seven decided to partake in some champagne in effort to perfect her social skills. Upon drinking a single glass of champagne, she became drunk, and experienced what she described as the "malfunctioning" of her "visual processors and motor cortex." Upon the discovery of Seven having a blood synthehol level of 0.5, The Doctor escorted her to Sickbay to give her an injection of inaprovaline to counteract the effects. (VOY: "Timeless")
