There are different opinions on who the appropriate decision makers are for extremely premature infants. Some argue the responsibility should fall to the parents, and others argue the neonatal experts should be responsible for decision making. This study explored parental perceptions of their involvement in decision making in the neonatal intensive care (NICU). The NICU operated from the philosophy of Family Centered Care (FCC). FCC situates the parents as central to all aspects of their child’s care and as such, the parents should be well informed and actively involved in decision making. An interpretative descriptive approach was used to examine the experiences of seven parents who had infants born at 24-26 weeks gestation who were admitted to the NICU. Thematic analysis revealed that the culture of the NICU along with the relationships developed in the NICU had an impact on the parents’ perceptions of decision making.

Recent research suggests that by 4 months of age infants are able to individuate objects using form features, such as shape and size, but surface features, such as pattern and color, are not used until later in the first year (Wilcox, 1999). The current study sought to investigate two possible explanations for this developmental hierarchy. The visual maturation hypothesis suggests that the order in which infants use features to individuate objects corresponds to the order in which they are most readily processed by the developing visual system. A second hypothesis, the information processing biases hypothesis, suggests that infants are biased to attend to form features because form features provide information that is relevant to reasoning about object interactions. One way to test these hypotheses is to investigate infants' ability to individuate objects based on luminance. Luminance is detected at birth, so, according to the visual maturation hypothesis, luminance, like shape and size, will be used to individuate objects early in the first year. However, luminance is a surface property, so according to the information processing biases hypothesis, luminance, like pattern and color, will be used to individuate objects late in the first year. In the current study, 7-month-old (Experiment 1) and 11-month-old (Experiment 2) infants' use of luminance information in an object individuation task was investigated. The narrow-screen event-monitoring paradigm developed by Wilcox and Baillargeon (1998a) was used. Infants saw an event in which a ball moved behind a screen and a second ball emerged from behind the opposite edge of the screen. In one condition, the balls were identical, suggesting the presence of one object (same-luminance condition), and in another condition, the balls differed in luminance, suggesting the presence of two objects (different-luminance condition). The screen was either too narrow (narrow-screen event) or sufficiently wide (wide-screen event) to occlude two objects simultaneously. Seven-month-olds looked equally at each event, whereas 11.5-month-old's looked longer at the narrow-screen event in the different-luminance condition. These results suggest that 11.5-month-olds, but not 7.5-month-olds used luminance information to conclude that two distinct objects were involved in the event, thus supporting the information processing biases hypothesis.

The aim of the present study was to elucidate in a study with 4-, 6-, 8-, and 14-month-old German-learning children, when and how they may acquire the regularities which underlie Focus-to-Stress Alignment (FSA) in the target language, that is, how prosody is associated with specific communicative functions. Our findings suggest, that 14-month-olds have already found out that German allows for variable focus positions, after having gone through a development which goes from a predominantly prosodically driven processing of the input to a processing where prosody interacts more and more with the growing lexical and syntactic knowledge of the child.

The aim of these studies was to increase knowledge about hospital feeding routines in high-risk neonates. A retrospective medical chart review procedure was used to study routines at the neonatal units of two Swedish hospitals. In Papers I and II, the sample (Uppsala n=21 and Umeå n=21) comprised of small for gestational age (SGA) infants, in Papers III (Uppsala n=64 and Umeå n=59) and IV (n=127), the samples comprised of appropriate for gestational age (AGA) infants. Paper I indicated large enteral/oral milk volumes rendered i.v. administration of glucose unnecessary, reduced weight loss and helped SGA infants regain birth weight earlier. More rapid postnatal growth did not remain up to 18 months with corrected age in any growth variable (Paper II). In Paper III, effects were compared whether the infants’ volume of breast milk intake in hospital was estimated by “clinical indices” or determined by test-weighing. Infants treated in hospitals where test-weighing was practised attained exclusive breastfeeding at an earlier postmenstrual age (PMA), and they were discharged at an earlier PMA. However, the two study units were similar regarding the proportion of infants attaining exclusive breastfeeding. Paper IV revealed preterm AGA infants with higher standard deviation scores (SDS) at birth had more negative changes from birth to discharge for all growth variables. Conclusions: Papers I and II indicated that early initiation of enteral/oral feeding with proactive increases in milk volume was beneficial short term. No evidence was found for a proactive nutrition regimen with initial large volumes of milk resulting in a different pattern of growth up to the corrected age of 18 months. Test-weighing before and after breastfeeding might help infants to attain exclusive breastfeeding at an earlier PMA (study III). Finally, preterm AGA infants with higher SDS at birth are at higher risk of inadequate growth during their hospital stay (study IV).

The present study examined whether infants aged 3 to 9 months displayed an adult-like left visual field bias when processing dynamic faces. In Experiment 1 infants aged 6 to 9 months viewed videos of dynamic face stimuli. Eye tracking data revealed that these infants showed a left visual field bias by attending significantly more to the right side of the faces. In Experiment 2 a younger group of infants, aged 3 to 6 months, failed to demonstrate a group left visual field bias. Instead, some infants displayed a consistent left visual field bias whereas others displayed a consistent right visual field bias. To our knowledge, these findings provide the first eye-tracking evidence to suggest the existence of a left visual field bias in infancy.
