PAL: Pacifier Activated Lullaby is a pacifier fitted with an adapter, which houses a computer chip that activates a CD player outside the incubator. Developed in 2000 by Dr. Jayne M. Standley along with the Center for Music Research at Florida State University, the PAL is used during music therapy interventions in the neonatal intensive-care unit to promote and reinforce non-nutritive sucking (NNS) opportunities on premature infants. Dr. Standley found that infants could differentiate between silence and musical stimuli, which meant infants could be positively reinforced with music when they sucked with enough endurance and strength.〔(music and feeding )〕 The sensors in the PAL detect correct non-nutritive sucking characteristics and activate a CD player which reproduces lullabies through small speakers placed binaurally in the incubator above the infant's head.〔Jayne M. Standley "The effect of music reinforcement for non-nutritive sucking on nipple feeding of premature infants". Pediatric Nursing. 12 Aug, 2010. pg. 141〕 ==Music protocol== Lullabies are selected for this intervention by credentialed music therapists following these basic criteria: *no changes in tempo *no changes in volume level (65db scale C) *no key changes *higher vocal ranges (mainly female vocals) *the native language of the infant to promote language input opportunities〔Standley, J. (2000). The effect of contingent music to increase non-nutritive sucking of premature infants. Pediatric Nursing, 26(5), 493-499.〕 The music is sustained for 10 seconds after receiving the first suck, and fades out if it is not reactivated by another one, therefore making the presentation of musical stimuli contingent on the sucking behavior of the infant. Provisions are made in the protocol to discontinue the intervention if signs of infant distress are observed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pacifier-activated lullaby」の詳細全文を読む スポンサード リンク
