Infant crying signals distress to potential caretakers who can alleviate the aversive conditions that gave rise to the cry. The cry signal results from coordination among several brain regions that control respiration and vocal cord vibration from which the cry sounds are produced. Previous work has shown a relationship between acoustic characteristics of the cry and diagnoses related to neurological damage, SIDS, prematurity, medical conditions, and substance exposure during pregnancy. Thus, assessment of infant cry provides a window into the neurological and medical status of the infant. Assessment of infant cry is brief and noninvasive and requires recording equipment and a standardized stimulus to elicit a pain cry. The typical protocol involves 30 seconds of crying from a single application of the stimulus. The recorded cry is submitted to an automated computer analysis system that digitizes the cry and either presents a digital spectrogram of the cry or calculates measures of cry characteristics. The most common interpretation of cry measures is based on deviations from typical cry characteristics. Another approach evaluates the pattern across cry characteristics suggesting arousal or under-arousal or difficult temperament. Infants with abnormal cries should be referred for a full neurological evaluation. The second function of crying--to elicit caretaking--involves parent perception of the infant's needs. Typically, parents are sensitive to deviations in cry characteristics, but their perception can be altered by factors in themselves (e.g., depression) or in the context (e.g., culture). The potential for cry assessment is largely untapped. Infant crying and parental response is the first language of the new dyadic relationship. Deviations in the signal and/or misunderstanding the message can compromise infant care, parental effectiveness, and undermine the budding relationship. (c) 2005 Wiley-Liss, Inc.

“…The onset of both is regulated by physical maturation -even crying, since the cry of the prematurely born infant is quite feeble and differ ent in acoustic quality from that of the full term baby (Karelitz and Fisichelli, 1963). Both are deeply rooted in emotional reactivity.…”

“…Since the normal cry is not restored after nutritional therapy (Donzelli et al, 1994), the altered cry characteristics have been interpreted as an enduring consequence of CNS damage. This idea is compelling since various forms of brain damage, including asphyxia (Michelsson, 1971;Michelsson, Sirviö, & Wasz-Hockert, 1977a), bacterial meningitis (Michelsson, Sirviö, & Wasz-Hockert, 1977b), Down syndrome (Fisichelli & Karelitz, 1963;Karelitz & Fisichelli, 1962), and congenital hypothyroidism (Michelsson & Sirviö, 1976) have been found to produce differences in the cries of the infant.…”

The male offspring of rats provided with a protein deficient diet (6% casein) for 5 weeks prior to mating and throughout pregnancy were subjected to a brief period of isolation and cooling at postnatal Days (P)7, 9, and 11, and their ultrasonic vocalizations were compared with those of well-nourished pups. Calls were categorized into 12 different types based upon their sonographic patterns. Although call rates were equal, the call characteristics of the prenatally malnourished pups differed significantly from those of well-nourished controls. At P7, their mean peak sound frequency (irrespective of call type) was significantly higher, and constant frequency calls were of both higher frequency and longer duration. Over the age range studied, prenatally malnourished pups emitted a smaller variety of calls, with significantly fewer ascending frequency vocalizations while producing either significantly fewer (P9) or greater (P11) descending frequency calls. Altered crying patterns have been related to brain damage in human babies, with more abnormal cries being associated with more severe neurological impairment. Therefore, the present results most likely reflect altered central nervous system development and function. Ultrasonic vocalization characteristics in rat pups may provide a useful early marker of the severity of disturbance to the development of the central nervous system following an insult, and offer the potential for predicting the degree of functional and behavioral deficits later in life.
