Adults are sensitive to the physical differences that define ethnic groups. However, the age at which we become sensitive to ethnic differences is currently unclear. Our study aimed to clarify this by testing newborns and young infants for sensitivity to ethnicity using a visual preference (VP) paradigm. While newborn infants demonstrated no spontaneous preference for faces from either their ow...

the aim of the present investigation was to determine the effect of two karate techniques on the reduction in stereotypic behaviours in three 5-year-old boys with autistic disorders. the study included three boys with autistic disorders. a singlesubject method with a-b-a design was used. participants of the present study were required to exercise two karate techniques (zuki and mae-geri) for 12...

Human infants show a preference for listening to speech, but little is known about how infants listen to other naturally occurring sounds. Here, we test infants’ listening bias for speech against a range of naturally occurring sounds that share properties of speech to varying extents and we aim to better characterize the speech properties that attract infant attention. We compared 3-month-olds’...

The present study used an operant conditioning procedure and contour integration stimuli to test three-month-olds' sensitivity to both contour continuity and contour closure. The data demonstrate an immaturity of continuity detection and a lack of closure detection at that age, relative to a previous finding of a heightened sensitivity to closed contours in adult observers. This finding modifie...

OBJECTIVE Mild traumatic brain injury (mTBI) and postconcussion syndrome (PCS) are common among military combatants. Hyperbaric oxygen (HBO2 ) is a proposed treatment for these conditions, but it has not been rigorously studied. The objective of this study was to determine the effects of HBO2 by 3 months post compression at 2 commonly employed dosing levels to treat PCS; whether specific subgro...

To investigate the nature of the young infant's social competence, the effect of depressed maternal expression during face-to-face interaction was examined using an experimental analogue of maternal depression. Subjects were 12 female and 12 male infants, ages 96-110 days, and their mothers. 2 counter-balanced experimental treatments consisted of 3 min of normal maternal interaction and 3 min o...
