Concurrent Schedule Performance with Young Infants
… Procedure. During daily sessions, three young infants were exposed to several concurrent variable-interval schedules. A mobile rotation, contingent on a foot kick, was occasionally available on each schedule component. Head turns served as the changeover response. Relative time allocation …

Young Infants' Knowledge About Self -Propelled Objects
… are in line with evidence suggesting that young children distinguish animate from inanimate objects and reason about animate objects in terms of their psychological and biological properties. Future research can further examine how infants' concept of self-propelled objects relates to young …

The control of reaching movements by young infants
… Samples of reaches were obtained from groups of infants aged 4.5, 6 and 7.5 months as split-screen video recordings, which were then transcribed as sequences of (X,Y,Z) hand coordinates. There was an improvement in overall efficiency in reaching across the three age groups. Movement paths were …

Effects of Delayed Auditory Feedback on Young Infants’ Crying
… this, the present study manipulated newborn infants’ perceptual experience during a cry bout through use of delayed auditory feedback (DAF). Atypical cry productions during DAF would suggest that newborn crying is under higher levels of cortical control than previously assumed. Infants’ …

Who's got guts? Young infants expect animals to have insides
… and psychological reasoning, or whether from a young age children endow animals with biological properties. Here we demonstrate that 8- month-old infants already expect novel objects they identify as animals to have insides. Infants detected a violation when an object that was self-propelled and …

An exploration of psychological flexibility and self-compassion among parents of young infants
… Distress and Adjustment in Parents of Preterm Infants<br/>Description: A quantitative analysis of 215 participants using multiple hierarchical regressions revealed psychological flexibility and self-compassion as unique predictors of psychological distress in parents of preterm infants. …

Young infants' attention and emotional responses to dynamic and static bimodal displays of affect
… infant perception and expression of affect. Nine infants were studied longitudinally at 2 months and at 3 1/2 months using a dynamic visual display that consisted of a videotape of a woman moving her face while expressing happiness or sadness. A second group of 10 infants were studied similarly …

Taking the 'Mother' out of 'Motherese': young infants' preference for mothers' use of infant-directed speech
… on infant perception of speech has shown that infants prefer their mother's voice over the voice of an unfamiliar female. Additionally, infants show a preference for the type of speech that is normally directed towards infants, known as infant-directed (10) speech. The linguistic and prosodic …

The Role of Antibodies to <i>Plasmodium falciparum</i> Merozoite Antigens in the Resistance of Young Infants to Febrile Malaria and Their Place as a Biomarker in the Detection of Malaria Transmission Hotspots
… relation to the incidence of febrile malaria in young children, with the specific objective of investigating their contribution to the apparent resistance of young infants to febrile malaria. We have also analysed the dynamics of antibodies in relation to previously established protective …

The development of spatially-accurate reaching behaviour in early infancy
This study was concerned with young infants capacity to coordinate their perception of the spatial characteristics of objects with their reaching and prehensile behaviours. The reaching behaviour of infants ranging in age from two to seven months was videotaped to determine whether they tended to …

Fairness expectations in the first year of life
… year have been mixed, leaving it unclear whether young infants possess an expectation of fairness. The present research examined the possibility that young infants might expect windfall resources to be divided equally between similar recipients but might demonstrate this expectation only under …

Interrogating the infant mind with fMRI
… perceptual and cognitive processes in infants’ brains. For two decades scientists have attempted to use functional magnetic resonance imaging (fMRI) to study infant perceptual and cognitive function. However, it remains unclear whether the basic structure of adult cortical organization …

Infants' reasoning about collision events
The present research investigated young infants' understanding of events in which a moving object collides with a stationary object. In the first set of experiments, 2.5-month-old infants were presented with collision and no-collision events. In the collision events, a cylinder rolled down a ramp …

The STRATA Study: Structural Antecedents of Tdap Administration in Obstetrical Practices in the Midwestern United States
Every year in the United States, young infants die from pertussis. The incidence of pertussis among infants exceeds that of all other age groups. Protection is only available if the mother receives the tetanus, diphtheria, and acellular pertussis (Tdap) vaccine during pregnancy, providing passive …

The impact of myeloid derived suppressor cells on vaccine immunogenicity in South African HIV-infected and uninfected mothers and their infants
BACKGROUND: Each year over 4 million infants die from infections, of which many are vaccinepreventable. Young infants respond poorly to vaccines, but the basis of reduced immunity is controversial. We hypothesized that myeloid-derived suppressor cells (MDSC) that might be induced during gestation, …

Infants reason about functional information embedded in means-end sequences
For young infants, knowledge of physical objects and animate agents seems highly rigid, with no information combined across domains. Adult cognition, however, is more flexible. In this thesis, I use a special category of object—a tool—that can only be reasoned about appropriately if information is …

Using music to facilitate infant word learning
… on infant word-object learning suggest that infants as young as 6-months of age are capable of learning word-object relationships when labeled by their mother (Matayaho & Gogate, 2008). Yet, the unexplored topic that music could influence infants' learning led to the conduction of this …

Effects of maternal sleep deprivation on maternal sensitivity and contingent responsiveness
… and the accompanying consequences are parents of young infants. The present study explored how sleep deprivation, resulting from infant night awakening, affects the face-to-face interaction between mothers and their 3- to 4-month-old infants. Contrary to the proposed hypotheses the groups did not …
