Establishing the Reliability and Developmental Validity of a Neurobehavioral Assessment for Preterm Infants: A Methodological Process

The Neurobehavioral Assessment of the Preterm Infant was developed in 3 phases: a pilot study, an exploratory study, and a validation study. In the exploratory study, clusters characterized by conceptual cohesion and face validity were systematically subjected to statistical analyses to determine whether they also had high test-retest reliability and developmental validity. In the validation study, a shortened version of the test was used with an independent cohort of 290 preterm infants. A step-by-step methodological process was used to test whether the results from the exploratory study would generalize over cohorts, different versions of the test, different hospitals, and changes in examiners. This process yielded 7 highly stable, developmentally valid, and representative preterm neurobehavioral functions that generalized over the exploratory and the validation studies. These were: motor development and vigor, scarf sign, popliteal angle, alertness and orientation, percent asleep ratings, irritability, and vigor of crying.     

How Symbolic Experience Shapes Children's Symbolic Flexibility

The current experiments asked whether children with dual‐symbolic experience (e.g., unimodal bilingual and bimodal) develop a preference for words like monolingual children (Namy & Waxman, 1998). In Experiment 1, ninety‐five 18‐ and 24‐month‐olds, with monolingual, unimodal bilingual, or bimodal symbolic experience, were tested in their willingness to treat digitized sounds as referents. In Experiment 2, forty‐seven 24‐month‐olds, with the same types of symbolic experience, were tested in their willingness to treat novel words as referents. Monolingual children performed in ways indicative of a growing preference for words, whereas children with dual‐symbolic experience performed in ways indicative of consistency in symbolic flexibility over time. Results suggest that the developmental trajectory of children's symbolic flexibility might depend on their symbolic experience.     

Exploring The Issues of Incorporating Cultural Differences in Education: A Curriculum Journey in Playwriting

In response to a mandate to develop a more welcoming university for students, especially those of Aboriginal inheritance, we set out on a journey for ways of accommodating cultural differences in our university classrooms. Over the course of a year, we met regularly and audiotaped our conversations. By talking, transcribing, writing, and rewriting, we carried our understandings forth in a recursive manner. In our efforts to represent the ideas that arose in our conversations, the conceptual movements in our thinking, and the insights that evolved, a play took shape. In the play, three characters evolve their understandings over the course of four acts. In this article, we reflect on the conditions that produced the play; we comment on the process of writing the play; and we share the understandings, insights, and transformations that occurred in our desire to live well amidst differences.     

Stable individual differences in developmentally changing preterm infants: a replicated study

In a longitudinal study with the Neurobehavioral Maturity Assessment (NB-MAP), developmental changes and stability of individual differences were assessed in 2 independent samples of preterm infants ranging from 32 weeks conceptional age to term. Individual stability of response was assessed using regression analysis with repeated measures on subjects. The large majority of the functions tested showed highly significant developmental gains with age and highly significant individual stability of performance across age. These findings replicated well across the 2 cohorts. The results are discussed in the light of the neurobiological stage of development of preterm infants during the last 8 weeks prior to term.
