Which relaxation technique involves envisioning positive scenes to alleviate anxiety?

The correct choice is guided imagery because it specifically focuses on using visualization to create a calming mental environment. This technique involves imagining serene and positive scenes, which can help shift a person's focus away from anxiety-inducing thoughts, thereby facilitating relaxation and a sense of peace. When an individual engages in guided imagery, they may picture places such as a tranquil beach or a peaceful forest, allowing their mind to experience a sensory escape that directly counters feelings of stress and anxiety.

While meditation is also a relaxation technique that can contribute to reducing anxiety, it typically involves a broader practice of mindfulness or concentration rather than specific visualizations of positive scenes. Biofeedback, on the other hand, relies on observing physiological signals and learning to control bodily functions to reduce stress, which does not specifically involve visualization. Lastly, progressive muscle relaxation focuses on the physical aspect of tension release by alternating between tensing and relaxing different muscle groups, rather than employing mental imagery. Thus, guided imagery is uniquely suited for the purpose of alleviating anxiety through visualization.
