A new study from researchers at the Hebrew University of Jerusalem shows that people with depressive symptoms tend to interpret neutral situations more negatively when surrounded by unrelated negative visuals. This “emotional spillover” effect has important implications for understanding and treating depression in Thailand, where mental health remains a sensitive topic, and points to new ways to strengthen emotional resilience in a rapidly changing society.
In Thai life, atmosphere shapes mood—from the bustle of street markets to the confusion of traffic in Bangkok. Now science confirms that surrounding context can strongly influence emotional responses, particularly for those with depressive tendencies. The study explored how peripheral visual information—background images not directly connected to the core task—affects emotional experience. More than 270 university students were shown images with varying emotional content, while surrounded by neutral, negative, or positive visuals.
Results were clear. Individuals with higher levels of depressive symptoms judged neutral images as more negative when they appeared beside negative surroundings. Positive or neutral periphery did not produce the same effect. Even more surprising: positive surroundings had limited ability to counteract negative reactions. This challenges the popular notion, especially in Thai wellness circles, that positive thinking or a positive environment can easily offset negativity.
A lead professor explained that emotional experiences are rarely driven by a single stimulus. This research suggests that people—especially those with depressive tendencies—are vulnerable to the spillover of surrounding negativity, even when it is not directly relevant to the situation at hand. Many Thais recognize how crowded, noisy environments can intensify stress, underscoring how everyday settings—from crowded commutes to doom-scrolling on social media—can overwhelm someone coping with depression.
The study also points to an emotional asymmetry: negative cues from the surrounding environment exert a stronger influence on interpretation than positive ones. A doctoral researcher noted that negative context may shape perception more than affirmative cues, particularly for those with depressive symptoms. This may help explain why some individuals with depression view the world through a darker lens, even in ordinary settings.
Data from Thailand’s public health landscape show rising mental health concerns since the COVID-19 pandemic, with urban residents reporting high stress, burnout, and depressive symptoms. Economic pressures, social isolation, and digital overload contribute to this trend. Stigma around mental illness remains a barrier in many communities, where depression is still sometimes viewed as a personal shortcoming rather than a medical condition. Research like this helps clarify the cognitive and perceptual dimensions of depression, moving beyond simplistic explanations of willpower.
The findings have direct implications for Thailand’s urban design, advertising, and digital environments. Social media feeds filled with negative content can disproportionately affect Thais facing depressive symptoms, even when users merely scroll past distressing imagery. Negative advertising, sensational headlines, or crowded public spaces may contribute more to emotional strain than previously understood. For Buddhist communities, the idea of equanimity is challenged by the limits of positive surroundings as a remedy for inner turmoil.
Therapists and families may use these insights to help individuals recognize and regulate the impact of peripheral negativity—whether from social media, advertising, or the physical environment. Building awareness of contextual triggers can inform strategies to strengthen emotional resilience. In practice, Thai schools, workplaces, and digital platforms could be designed to prioritize calm, safe spaces and positive cues. Therapeutic approaches might incorporate guidance on managing environmental stressors alongside mindset work.
Mental health professionals across Thailand, including clinicians in major urban hospitals and university counseling centers, can integrate these insights into cognitive-behavioral and mindfulness-based therapies. Educational materials from national health authorities may emphasize the importance of environmental design in mental well-being, suggesting steps to reduce exposure to pervasive negative cues. Even community meditation initiatives could incorporate considerations of visual surroundings to support mindful practice.
This research calls for a broader policy perspective in Thailand—one that considers living environments, the design of digital information ecosystems, and the tone of public communications. Thailand’s blend of tradition and modernity offers both challenges and opportunities for applying these insights to everyday life, from neighborhood parks to social media platforms.
Looking ahead, experts anticipate that as urbanization and digital connectivity continue to rise, the impact of peripheral negativity will grow. Further studies will be needed to tailor interventions for Thai youth, older adults, and diverse communities—building resilience in a world of constant stimulation.
Practical takeaways for Thai readers are clear. Be mindful of your surroundings, both offline and online. If you or a loved one experiences persistent low mood, remember that the environment can influence emotions. Consider reducing exposure to negative media, structuring living and workspaces to emphasize calm and positive cues, and seeking professional support when needed. Evidence indicates that sometimes the most effective step toward emotional health involves shaping the world around you, not only changing your mindset.
