Cluttered environments refer to physical spaces that are disorganized, messy, and filled with numerous objects or items. Research in this area typically focuses on understanding the impact of clutter on individuals' mental and emotional well-being, as well as cognitive processes such as attention, memory, and decision-making. Studies have shown that cluttered environments can lead to increased stress, reduced productivity, and poorer mental health outcomes. Researchers also examine strategies for decluttering and organizing spaces to improve overall well-being and cognitive functioning.
