to the child. This could be a real object like a blanket or a teddy bear, but other "objects", such as a melody or a word, can fulfill this role as well. This object represents all components of "mothering", and it means that the child itself is able to create what it needs as well. It enables the child to have a fantasized bond with the mother when she gradually separates for increasingly longer periods of time. The transitional object is important at the time of going to sleep and as a defense against anxiety. In a study conducted in Brazil, children who used transitional objects were able to calm down and go to sleep more easily than children who did not use transitional objects. In a later stage of the development, the child no longer needs the transitional object. It is able to make a distinction between "me" and "not-me", keeping inside and outside apart and yet interrelated. This development leads to the use of illusion, symbols and objects later on in life. Winnicott related the concept of transitional object to a more general one, transitional phenomena, which he considered to be the basis of science, religion and all of culture. Transitional objects and phenomena, he said, are neither subjective nor objective but partake of both. In Mental Space, Robert Young has provided an exposition of these concepts and has generalized their role into psychic phenomena in adult life. Research with children on this subject was performed at the University of Wisconsin–Milwaukee by Richard H. Passman and his associates. Among other findings, they showed that security blankets are appropriately named – they actually do give security to those children attached to them. Along with other positive benefits, having a security blanket available can help children adapt to new situations, aid in their learning, and adjust to physicians' and clinical psychologists' evaluations. Passman's research also points out that there is nothing abnormal about being attached to them. In the United States, about 60% of children have at least some attachment to a security object. A bedtime toy is often used by children while going to sleep. It is typically a plush toy or something of that nature that children can cuddle up with while going to sleep. It is sometimes combined with a nightlight. Bedtime toys are typically of an animal, such as the common teddy bear, or any other
