◐Partially Supported

Training the brain to recognize the long-term benefits of activities like taking a walk is crucial for productivity.

◐Partially SupportedTo make better decisions, establish a heuristic to automate less important decisions and avoid making significant decisions when fatigued or in a 'hot state'.

◐Partially SupportedDecisions are harder to make in a hot state, such as when hungry, compared to a cold state after eating.

◐Partially SupportedFraming an activity as a reward can increase its salience and encourage beneficial behaviors.
