Final answer:
Positive psychologist Mihaly Csikszentmihalyi describes 'flow' as a state of intense focus on an activity that is both effortless and fulfilling. Flow occurs when there is a balance between the challenge of the task and one's skill level, leading to a sense of joy and accomplishment.
Step-by-step explanation:
Positive psychologist, Mihaly Csikszentmihalyi, refers to experiences of timeless, effortless focus on an activity as flow. The concept of flow is a state in which individuals become completely immersed in an activity to the point where it becomes effortless, yet remains engaging and fulfilling. This psychological state is characterized by intense concentration, a high degree of focus, and a sense of achievement and joy.
Flow states require a balance between challenges and skills, and they are more likely to occur in individuals who have achieved a level of proficiency in the task at hand. Unlike automatic pilot, where an activity is done without conscious thought, flow is pleasant and purposeful. Csikszentmihalyi's research suggests that entering a state of flow can greatly contribute to personal happiness and productivity.
