Decreasing Anxiety in Stutterers through the Association between “Purpose in Life/Ikigai” and Emotions

Riichiro Ishida


The human prefrontal lobe is more evolved than those of other mammals. As such, every person has an innate need to establish a meaningful life, often referred to as “Purpose in life (PIL)/ikigai”, using the functioning of their prefrontal lobes. PIL/ikigai psychologically, and the prefrontal lobe physiologically, have common functions such as ambition, regulating emotion, and integrating psychological events. PIL/ikigai contributes to a decrease in anxiety influenced by a need for approval from others and stimulates pleasure and comfort, which may be related to the well-balanced secretion of neurotransmitters such as serotonin, dopamine, and ?-endorphin. Thus, a stutterer feels stress, i.e., anxiety, caused by perceived failure when engaging in conversations with others, which may be related to an imbalanced secretion of serotonin and dopamine. Therefore, previous work has suggested that PIL/ikigai may decrease anxiety in stutterers by decreasing the symptoms associated with stuttering.
