Psychology is the science of behavior and mind, embracing all aspects of conscious and unconscious experience as well as thought behaviors. Poor workstation designs can lead to increased cycle times, low quality of work, as well as exposure to high forces and awkward postures, thereby increasing the amount of psychological stress placed on an individual at work. Stress can also arise from the poor design of controls and displays that make it difficult for the operator to interpret information. Increased stress can directly influence a worker’s behavior. Studies have shown that prolonged stress can lead to a decrease in cognitive function and human performance.
