Visual exploration paradigms involving object arrays have been used to examine salience of social stimuli such as faces in ASD. Recent work suggests performance on these paradigms may associate with clinical features of ASD. We evaluate metrics from a visual exploration paradigm in 4-to-11-year-old children with ASD (n = 23; 18 males) and typical…

Early facial emotion recognition is hypothesized to be critical to later social functioning. However, relatively little is known about the typical intensity thresholds for recognizing facial emotions in preschoolers, between 2 and 4 years of age. This study employed a behavioral sorting task to examine the recognition of happy, fearful, and angry…

Faces convey important information about the social environment, and even very young infants are preferentially attentive to face-like over non-face stimuli. Eye-tracking studies have allowed researchers to examine which features of faces infants find most salient across development, and the present study examined scanning of familiar (i.e.,…

The current study examines the processing of upright and inverted faces in 3-year-old children (n = 35). Event-related potentials (ERPs) were recorded during a passive looking paradigm including adult and newborn face stimuli. We observed three face-sensitive components, the P1, the N170 and the P400. Inverted faces elicited shorter P1 latency and…

Here we report evidence from a new eye-tracking measure of relational memory that suggests that 9-month-old infants can encode memories in terms of the relations among items, a function putatively subserved by the hippocampus. Infants learned about the association between faces that were superimposed on unique scenic backgrounds. During test…

To examine the ontogeny of emotional face processing, event-related potentials (ERPs) were recorded from adults and 7-month-old infants while viewing pictures of fearful, happy, and neutral faces. Face-sensitive ERPs at occipital-temporal scalp regions differentiated between fearful and neutral/happy faces in both adults (N170 was larger for fear)…

In first of 2 experiments, an early negative component of 400 4 to 6 year olds distinguished between happy and angry expressions. A later positive component distinguished between target and nontarget events. Both components were observed in a second experiment. Results are discussed in the context of children's allocation of attentional and memory…

The goal of the current study was to assess general maturational changes in the ERP in the same sample of infants from 4 to 12 months of age. All participants were tested in two experimental manipulations at each age: a test of facial recognition and one of object recognition. Two sets of analyses were undertaken. First, growth curve modeling with…

Event-related potentials (ERPs) were recorded from infants shown sets of familiar faces presented frequently and infrequently, and a set of novel faces presented infrequently, and correlated with infant emotional behavior and cortisol levels. Found that infants scoring higher on the normative ERP factor were more distressed during parent…

Highlighting current literature concerning infants' ability to perceive motion, this paper discusses the sensory apparatus that makes motion perception possible. Reviews of the physiology, anatomy, and sensory capabilities of the infant's visual system, as well as a discussion of the neural physiological mechanisms that govern the visual system,…

Event-related potentials (ERPs) of children and adults were measured while subjects observed pictures of facial expressions. Adults had greater ERP responses to happy than to angry faces, whereas children had greater ERP responses to angry than to happy faces. (BC)

A series of studies has investigated the possibility that human infants performing tasks exhibit something like the P300, a positive-going brain wave associated with task performance and the updating of working memory among adults. Findings indicate that, when infants have the opportunity to form a template against which to compare a previously…
