This research encompasses two experimental studies aimed at exploring the potential of behavioral nudges to instigate positive change. The first experiment evaluates the use of visual cues, such as posters and footprints, to nudge individuals towards choosing stairs over elevators, promoting physical activity. The second delves into the psychological impact of personalized praise on college students' motivation, efficacy, and confidence, correlating these factors with academic performance. By integrating quantitative and qualitative research methods, the studies intend to assess the effectiveness of these behavioral nudges in directing behavior toward desirable outcomes. Contributing to the expanding discourse on behavioral economics and nudge theory, this research underscores the transformative potential of strategic nudges in not only encouraging healthier physical habits and academic engagement but also in broader applications for behavioral modification. These findings illuminate the versatility and efficacy of nudges as tools for positive behavioral intervention across diverse contexts.
