The author tested the hypothesis that attachment to comfort objects is based on the sensory processing characteristics of the individual. Fifty-two undergraduate students with and without a childhood comfort object reported sensory responses and performed a tactile threshold task. Those with a comfort object described their object and rated their attachment to it. Participants with a strong attachment liked the texture of their comfort object and sleeping with it. Smell sensitivity in childhood, seeking out tactile stimulation as children, and tactile threshold predicted the intensity of object attachment. Participants with comfort objects showed a higher tactile threshold and reported seeking out more tactile stimulation as children than participants without a comfort object did. These findings suggest that children with an object attachment seek out more sensory stimulation through touch, which in turn is soothing. Results support growing research linking sensory processing to psychological functioning. (Contains 5 tables and 1 note.)
