Theoretical interfaces in the acute paediatric context: A psychotherapeutic understanding of the application of infant-directed singing

Psychotherapy literature provides a theoretical understanding of parent-infant attachment. This article will reflect upon the specific need to give thoughtful consideration to those infants admitted to the acute-care setting, such as neonatal and paediatric intensive care units, and the potential for this environment to affect infant development and the parent-infant relationship. Infant-directed singing, as described in this article, is an improvised form of vocal interaction that is specifically informed by an understanding of the musical parameters of pitch, rhythm, phrasing, timbre, register, dynamic, tempo and silence. This article will detail a theoretical understanding of using infant-directed singing to foster parent-infant interaction within the acute care environment. In particular, the potentially sensitive, reciprocal and engaging nature of infant-directed singing, coupled with its ability to promote and support maternal demonstrations of empathy, will be discussed with a view to the psychological and physical development of the hospitalised infant.

Auditory-visual speech integration by prelinguistic infants: Perception of an emergent consonant in the McGurk effect

The McGurk effect, in which auditory [ba] dubbed onto [go] lip movements is perceived as da or tha, was employed in a real-time task to investigate auditory-visual speech perception in prelingual infants. Experiments 1A and 1B established the validity of real-time dubbing for producing the effect. In Experiment 2, 4(1)/(2)-month-olds were tested in a habituation-test paradigm, in which 2 an auditory-visual stimulus was presented contingent upon visual fixation of a live face. The experimental group was habituated to a McGurk stimulus (auditory [ba] visual [ga]), and the control group to matching auditory-visual [ba]. Each group was then presented with three auditory-only test trials, [ba], [da], and [deltaa] (as in then). Visual-fixation durations in test trials showed that the experimental group treated the emergent percept in the McGurk effect, [da] or [deltaa], as familiar (even though they had not heard these sounds previously) and [ba] as novel. For control group infants [da] and [deltaa] were no more familiar than [ba]. These results are consistent with infants'perception of the McGurk effect, and support the conclusion that prelinguistic infants integrate auditory and visual speech information.

Classification of perinatal deaths: Development of the Australian and New Zealand classifications

Classifications of perinatal deaths have been undertaken for surveillance of causes of death, but also for auditing individual deaths to identify suboptimal care at any level, so that preventive strategies may be implemented. This paper describes the history and development of the paired obstetric and neonatal Perinatal Society of Australia and New Zealand (PSANZ) classifications in the context of other classifications. The PSANZ Perinatal Death Classification is based on obstetric antecedent factors that initiated the sequence of events leading to the death, and was developed largely from the Aberdeen and Whitfield classifications. The PSANZ Neonatal Death Classification is based on fetal and neonatal factors associated with the death. The classifications, accessible on the PSANZ website (http://www.psanz.org), have definitions and guidelines for use, a high level of agreement between classifiers, and are now being used in nearly all Australian states and New Zealand.
