A new eye-tracking study uncovers how depression shapes what people notice in everyday environments. Researchers found that individuals with major depressive disorder spend more time looking at threatening and neutral images while showing fewer rapid eye movements. This pattern suggests a focused attention on negative or ambiguous content that could reinforce pessimistic thinking. The study appears in the Journal of Affective Disorders, with insights that are relevant for clinical practice and daily life in Thailand and beyond. According to recent coverage by PsyPost, the study highlights the subtle ways depression influences information processing.
In the research, 100 adults diagnosed with major depressive disorder were matched with 100 healthy participants by age, gender, and education. Using eye-tracking technology, scientists measured viewing time for threatening, positive, and neutral images. Depressed participants lingered longer on threatening and neutral images and exhibited reduced saccades, indicating limited visual exploration compared with their healthier peers.
Depression remains a growing concern in Thailand. Thailand’s Department of Mental Health reports that depression is among the leading causes of disability, affecting about 1.5 million people and contributing to social and economic burdens. Stigma continues to hinder diagnosis and treatment, with many Thais associating mental health symptoms with weakness or spiritual imbalance rather than seeking help.
Traditionally, depression signs include persistent sadness, fatigue, appetite or weight changes, diminished interest, and trouble concentrating. The new findings point to a less visible feature: attentional bias. People with depression may subconsciously focus more on negative or threatening information and ignore positive cues. This could entrench negative thinking patterns and feelings of hopelessness. The concept resonates in Asian cultures where reading subtle cues and indirect communication are common, and where concerns about “face” can discourage open discussion of distress. The World Health Organization notes that understanding cognitive processes in depression can inform more effective interventions.
Participants completed tasks involving a range of images—from aggressive animals and accidents (threatening) to smiling faces and tranquil landscapes (positive) and neutral objects or people (neutral). The depressed group showed prolonged gaze on threatening and neutral content, with little sustained focus on positive imagery. In contrast, healthy participants did not show similar attentional patterns.
Experts in Bangkok describe how these findings align with Thai therapeutic approaches that emphasize mindfulness and cognitive reappraisal. A consultant psychiatrist from a major Bangkok hospital noted that Thai care now increasingly considers attention and information processing as part of depression treatment. Clinicians view eye-tracking as a valuable objective measure to gauge progress alongside traditional self-reports.
In Thailand’s mental health landscape, Cognitive Behavioral Therapy (CBT) is gaining traction for addressing maladaptive attentional patterns by helping patients identify and redirect negative automatic thoughts. The Royal College of Psychiatrists of Thailand has integrated digital eye-tracking and attention-training programs into leading hospital services, using international research as a model for early intervention. A senior clinical psychologist at a public hospital in Chiang Mai highlighted the potential of eye-tracking to monitor recovery beyond self-report alone.
Thai culture blends Western medicine with Buddhist philosophy, emphasizing balance and mindful awareness. Local proverbs—such as “the mind is the master, the body is the servant”—mirror a cultural understanding that attention shapes reality. In Buddhist psychology, wise attention is taught as a skill to guard the mind from unhealthy preoccupations, a concept that parallels attentional-bias modification in Western research.
Looking ahead, integrating eye-tracking into routine mental health assessments could offer objective markers for depression. In schools, where anxiety and depression have surged post-pandemic, educators can use related insights to craft classroom strategies. Interventions might help students redirect attention toward positive social interactions and achievements.
As Thailand modernizes its healthcare system and works to reduce stigma, these findings can spark important conversations about depression’s inner workings. Understanding that depression involves involuntary attention patterns—not merely negative thinking—may foster empathy and encourage timely professional support.
Practical guidance for Thai readers includes cultivating mindful awareness of one’s thought and attention patterns. Simple daily practices—noting when worries dominate and consciously shifting focus to positive experiences—can begin to counteract these biases. For persistent symptoms, seeking assessment by a mental health professional familiar with attentional training or cognitive therapy is advised.
Depression is common, but this research shows its impact on everyday perception runs deeper than expected. By understanding how the mind pays attention, individuals and communities can take steps toward more resilient mental health.

The study’s approach aligns with current Thai clinical practices that emphasize mindfulness and cognitive strategies in treatment. Data from Thailand’s Department of Mental Health underscores the national relevance of these findings.
