The role of visual arts in facilitating the expression of repressed emotions and unspoken experiences is based on the fact that not all human emotional experiences can necessarily be transmitted through verbal language, and some internal feelings, memories, and conflicts may be experienced and stored non-verbally. Visual arts such as painting, drawing, collage, illustration, and working with color and form, make it possible to transform a part of these internal experiences into an external and visible representation. In this process, a person can express emotions such as fear, anger, sadness, shame, loneliness, and helplessness in the form of visual elements without the need to directly explain their experience. From a psychological perspective, externalizing emotion can create a safe distance between the individual and the experience, allowing them to observe, identify, and reflect on their feelings. This distancing does not mean eliminating or forgetting the experience, but it can provide conditions for gradual processing and increased feelings of control. In art therapy, the value of a work of art is not merely in its beauty or technical skill, but also in the process of creation and the meaning that the person attributes to the work. Color, line, shape, image space, and subject choice can become tools for non-verbal communication, but their interpretation must be based on the individual's personal narrative and it is not possible to consider a fixed and universal meaning for each symbol. Research in the field of art therapy has shown that artistic activities in some clinical populations can be associated with increased emotional expression, self-awareness, and a decrease in psychological distress, however, the extent and persistence of these effects vary in different studies and depend on the type of intervention, the individual's condition, and the quality of treatment delivery. One of the important applications of visual arts in the face of traumatic experiences is to create the possibility of gradually expressing content that is difficult for the person to express directly or exceeding their emotional capacity. The person can first represent his experience symbolically or metaphorically, and then, if ready, discuss the meaning of the work with the therapist. This process, if implemented correctly, can help organize scattered memories, identify emotions associated with the experience, and reconstruct its personal meaning. In patients with physical illnesses and cancer, visual arts can also provide a platform for expressing fear of illness, worry about the future, grief caused by physical changes, anger, and feelings of loss. In children and adolescents, painting and visual activities can be complementary communication tools, especially when the ability to verbally express emotion has not yet been fully formed. However, not every painting or image should be interpreted as a definitive sign of a psychological problem; the meaning of the work should be determined through dialogue, behavior observation, and a comprehensive psychological evaluation. In terms of emotion regulation, artistic activity can shift a person's attention from being immersed in an emotional experience to a purposeful activity, enhancing a sense of agency through focus, choice, organization, and mood. Also, the experience of transforming a vague emotion into an image may help to name and separate emotions, leading a person from a mere emotional reaction to observing and processing the experience. Visual arts can be used in individual and group psychotherapy, trauma-based interventions, psychosocial rehabilitation, and psycho-oncology. In a group setting, viewing works and discussing shared experiences can enhance a sense of belonging and emotional validation, although it is essential to respect the privacy and psychological boundaries of members. One of the main challenges of this intervention is the possibility of activating intense emotions when dealing with difficult experiences, so it is important to create a sense of security, regulate the intensity of the activity, and pay attention to the person's emotional tolerance capacity. Also, some people may not connect with artistic activity or have limited participation due to physical, cultural, or personal limitations. Research limitations include differences in art therapy methods, art tools, research samples, and measurement methods, which make it difficult to compare the results directly. It is suggested that future research use controlled designs, larger samples, and long-term follow-ups, and investigate the role of variables such as emotion regulation, self-awareness, resilience, and quality of life separately. Also, specialized training of therapists in the field of trauma, psychological evaluation, and professional ethics is necessary to prevent hasty and traumatic interpretations. In general, visual arts, as a complementary psychological language, can provide the possibility of externalizing difficult emotions, facilitating therapeutic communication, increasing self-awareness, and gradually reconstructing unspoken experiences, and if used purposefully and professionally, they can have an effective place in complementary psychological interventions.
