in psychoanalytic personality theory, the earliest stage in psychosexual development, lasting through the first 18 months of life, during which the oral zone is the center of the infant's needs, expression, gratification, and pleasurable erotic experiences; has a strong influence on the organization and development of the child's psyche.

In this case series, dysphagia appears to have resulted from cortical and extrapyramidal neurologic damage that led to disorganization of voluntary swallowing activity, including oral phase dysfunction with alterations in food capitation and labial closure, loss of food from the mouth, wrong positioning of the bolus, and bolus ejection.
In the infants in this series, the transfer of swallowing from a reflex activity to a complex voluntary sensorimotor process led to abnormal oral phase movements that disrupted normal swallowing after 3 months of age.
Generally, the oral phase of the contour consonant is voiced and appears contiguous to an oral segment in the phonetic sequence.
In Wetzels (1995, 2008) it was shown that syllable structure is an important clue to understanding the distribution of contour segments in this language: a consonant of the/{M,B}/class is realized with an oral phase when it belongs to a syllable with an oral nucleus.
Significantly, only when/{M,B}/consonants can be syllabified as margins of oral syllables they will emerge with an oral phase (4).
This gesture radically prevents pressure build-up in the vocal tract and allows a continuous voicing, which, obviously, leads simultaneously to the production of a plain nasal consonant (8), unless the velum is raised again before the consonant is released, in which case the resultant consonant has a nasal and an oral phase, as in the Mixtec examples in (3) above.
Inversely, when the contour segrnents are in free variation with nasal consonants ([mb] ~ [m]), the nasal consonants are lexical and the oral phase of the contour segments might be explained as the enhancement of an underlying oral/nasal contrast on vowels.
This conclusion is corroborated by the fact that the contour stops may occur in front of (surface) nasal diphthongs, as in the first example of (13), a fact which is not problematical from the point of view of VSE, because, as Wari has no rule of nasal assimilation, the oral phase is not affected by the nasality of a contiguous nasal segment.
The introduction of an oral phase could allow the United Kingdom and Spain to give their support and they are likely to have very many disputes in this realm over the Gibraltar problem.
Law students from 34 law schools from every region of the country competed in the written and oral phases of the Competition, arguing a moot case arising under the Age Discrimination in Employment Act of 1967.
The plan would also involve giving the Court the possibility to adopt practical instructions to the parties to improve upon the written and oral phases of the legal procedure, to update the references to the European Union Treaty, to renumber the Amsterdam Treaty and to adjust the number of Court Members as a result of Austria, Finland and Sweden joining the EU.
