Strokes are a way to measure attention and recognition between people, as defined by Eric Berne. Strokes can be positive or negative, verbal or nonverbal, and range from a casual nod to an intimate relationship. Individuals need strokes for physical, mental, and emotional development and survival; deprivation of strokes can lead to retardation, anxiety, depression, and even death. Both giving and receiving strokes have advantages like being free, motivating, improving personality, and increasing emotional well-being.
