Infants' Preference for ID Speech in Face and Voice Extends to a Non‐Native Language
Infants prefer infant‐directed (ID) speech. Concerning talking faces, previous research showed that 3‐ and 5‐month‐olds prefer faces that produce native ID than native adult‐directed (AD) speech, regardless of background speech being ID, AD or silent. Here, we explored whether infants also show a preference for non‐native ID speech. We presented 3‐ and 6‐month‐old infants with pairs of talking faces, one producing non‐native ID speech and the oth…

When forgetting fosters learning
Orientation Effects in the Development of Linear Object Tracking in Early Infancy
Infants' oculomotor tracking develops rapidly but is poorer when there are horizontal and vertical movement components. Additionally, persistence of objects moving through occlusion emerges at 4 months but initially is absent for objects moving obliquely. In two experiments, we recorded eye movements of thirty-two 4-month-old and thirty-two 6-month-old infants (mainly Caucasian-White) tracking horizontal, vertical, and oblique trajectories. Infan…
Infants’ learning of non‐adjacent regularities from visual sequences
Tracking adjacent (AD) and non‐adjacent (NAD) dependencies in a sequence of elements is critical for the development of many complex abilities, such as language acquisition and social interaction. While learning of AD in infancy is a domain‐general ability that is functioning across different domains, infants’ processing of NAD has been reported only for speech sequences. Here, we tested 9‐ to 12‐ and 13‐ to 15‐month‐olds’ ability to extract AxB …
Infants' identification of gender in biological motion displays
Infants' knowledge of social categories, including gender‐typed characteristics, is a vital aspect of social cognitive development. In the current study, we examined 9‐ to 12‐month‐old infants' understanding of the categories “male” and “female” by testing for gender matching in voices or faces with biological motion depicted in point light displays (PLDs). Infants did not show voice–PLD gender matching spontaneously (Experiment 1) or after “trai…
Rule learning transfer across linguistic and visual modalities in 7‐month‐old infants
Rule learning (RL) refers to infants’ ability to extract high‐order, repetition‐based rules from a sequence of elements and to generalize them to new items. RL has been demonstrated in both the auditory and the visual modality, but no studies have investigated infants’ transfer of learning across these two modalities, a process that is fundamental for the development of many complex cognitive skills. Using a visual habituation procedure within a …
Intermodal emotion matching at 15 months, but not 9 or 21 months, predicts early childhood emotion understanding
Emotion understanding is a crucial skill for early social development, yet little is known regarding longitudinal development of this skill from infancy to early childhood. To address this issue, the present longitudinal study followed 40 participants from 9 to 30 months. Intermodal emotion matching was assessed using eye tracking at 9, 15, and 21 months, and emotion understanding was measured using the Affective Knowledge Test at 30 months of ag…

Factors Facilitating Early Emotion Understanding Development
Children’s emotion understanding is crucial for healthy social and academic development. The behaviors influenced by emotion understanding in childhood have received much attention, but less focus has been placed on factors that may predict individual differences in emotion understanding, the principal issue addressed in the current review. A more thorough understanding of the developmental underpinnings of this skill may allow for better predict…
Quantifying Sources of Variability in Infancy Research Using the Infant-Directed-Speech Preference
Psychological scientists have become increasingly concerned with issues related to methodology and replicability, and infancy researchers in particular face specific challenges related to replicability: For example, high-powered studies are difficult to conduct, testing conditions vary across labs, and different labs have access to different infant populations. Addressing these concerns, we report on a large-scale, multisite study aimed at (a) as…
Real‐world scene perception in infants
The foci of visual attention were modeled as a function of perceptual salience, adult fixation locations, and attentional control mechanisms (measured in separate tasks) in infants ( N = 45, 3‐ to 15‐month‐olds) as they viewed static real‐world scenes. After controlling for the center bias, the results showed that low‐level perceptual salience predicts where infants look. In addition, high‐level factors also played a role: Infants fixated parts o…
Revisiting the Jezebel Stereotype
The overt objectification and dehumanization of Black people has a long history throughout the Western world. However, few researchers have explored whether such perceptions still persist implicitly and whether Black women are sexually objectified at an interpersonal level. We sought to address this gap by exploring whether Black women are sexually objectified to a greater extent than White women and whether target sexualization exacerbates this …
Limits of Object Persistence
Previous research indicated that 4‐month‐old infants perceive continuity of objects moving on horizontal trajectories but appear to have difficulty processing occlusion events involving oblique trajectories. However, because perception of continuity of vertical trajectories has not been tested, it is uncertain whether this indicates a specific deficit for oblique trajectories or a specific advantage for horizontal trajectories. We evaluated the c…
Relations of emotion-related temperamental characteristics to attentional biases and social functioning
The current study examined whether an important temperamental characteristic, effortful control (EC), moderates the associations between dispositional anger and sadness, attention biases, and social functioning in a group of preschool-aged children (N = 77). Preschoolers' attentional biases toward angry and sad facial expressions were assessed using eye-tracking, and we obtained teachers' reports of children's temperament and social functioning. …
Learning Stimulus‐Location Associations in 8‐ and 11‐Month‐Old Infants
Research on the influence of multimodal information on infants' learning is inconclusive. While one line of research finds that multimodal input has a negative effect on learning, another finds positive effects. The present study aims to shed some new light on this discussion by studying the influence of multimodal information and accompanying stimulus complexity on the learning process. We assessed the influence of multimodal input on the trial‐…
Development of Three‐Dimensional Completion of Complex Objects
Three‐dimensional (3D) object completion, the ability to perceive the backs of objects seen from a single viewpoint, emerges at around 6 months of age. Yet, only relatively simple 3D objects have been used in assessing its development. This study examined infants’ 3D object completion when presented with more complex stimuli. Infants ( N = 48) were habituated to an “L”‐shaped object shown from a limited viewpoint; then they were tested with volum…
Oculomotor Exploration of Impossible Figures in Early Infancy
Previous studies have revealed that young infants can distinguish between displays of possible or impossible figures, which may require detection of inconsistent depth relations among local line junctions that disrupt global object configurations. Here, we used an eye‐tracking paradigm to record eye movements in young infants during an object discrimination task with matched pairs of possible and impossible figures. Our goal was to identify diffe…
Trajectory perception and object continuity
Previous work has demonstrated that infants use object trajectory continuity as a cue to the constant identity of an object, but results are equivocal regarding the role of object features, with some work suggesting that a change in the appearance of an object does not cue a change in identity. In an experiment involving 72 participants, we investigated the effects of changing object shape and color, singly and in combination, on 4-month-olds' pe…
Eye‐Tracking as a Measure of Responsiveness to Joint Attention in Infants at Risk for Autism
Reduced responsiveness to joint attention (RJA), as assessed by the Early Social Communication Scales (ESCS), is predictive of both subsequent language difficulties and autism diagnosis. Eye‐tracking measurement of RJA is a promising prognostic tool because it is highly precise and standardized. However, the construct validity of eye‐tracking assessments of RJA has not been established. By comparing RJA an eye‐tracking paradigm to responsiveness …
Infants’ Response to Pictures of Impossible Objects
Previous work has shown that 4‐month‐olds can discriminate between two‐dimensional (2D) depictions of structurally possible and impossible objects [S. M. Shuwairi (2009), Journal of Experimental Child Psychology , 104, 115; S. M. Shuwairi, M. K. Albert, & S. P. Johnson (2007), Psychological Science , 18, 303]. Here, we asked whether evidence of discrimination of possible and impossible pictures would also be revealed in infants’ patterns of reach…
Systems in development
How do infants learn to perceive the backs of objects that they see only from a limited viewpoint? Infants' 3-dimensional object completion abilities emerge in conjunction with developing motor skills--independent sitting and visual-manual exploration. Infants at 4.5 to 7.5 months of age (n = 28) were habituated to a limited-view object and tested with volumetrically complete and incomplete (hollow) versions of the same object. Parents reported i…

Abstract Rule Learning for Visual Sequences in 8‐ and 11‐Month‐Olds
The experiments reported here investigated the development of a fundamental component of cognition: to recognize and generalize abstract relations. Infants were presented with simple rule‐governed patterned sequences of visual shapes (ABB, AAB, and ABA) that could be discriminated from differences in the position of the repeated element (late, early, or nonadjacent, respectively). Eight‐month‐olds were found to distinguish patterns on the basis o…
Development of Visual Selection in 3‐ to 9‐Month‐Olds
We examined changes in the efficiency of visual selection over the first postnatal year with an adapted version of a spatial negative priming paradigm. In this task, when a previously ignored location becomes the target to be selected, responses to it are impaired, providing a measure of visual selection. Oculomotor latencies to target selection were the dependent measure. Each trial consisted of a prime and a probe presentation, separated by a 6…

Perception of object unity in 2-month-old infants
The perception of object unity in partial occlusion displays was examined in 722-month-old infants. The infants were habituated to 1 of 3 displays depicting a rod undergoing lateral motion behind a box. In each display, more of the rod was visible behind the box than was previously available in prior studies of young infants' perception of occlusion. Posthabituation test displays consisted of 2 rod pieces (broken rod) and a complete rod, presente…
Learning by selection
The authors examined how visual selection mechanisms may relate to developing cognitive functions in infancy. Twenty-two 3-month-old infants were tested in 2 tasks on the same day: perceptual completion and visual search. In the perceptual completion task, infants were habituated to a partly occluded moving rod and subsequently presented with unoccluded broken and complete rod test stimuli. In the visual search task, infants viewed displays in wh…

Development of perceptual completion originates in information acquisition
Adults have little difficulty perceiving objects as complete despite occlusion, but newborn infants perceive moving partly occluded objects solely in terms of visible surfaces. The developmental mechanisms leading to perceptual completion have never been adequately explained. Here, the authors examine the potential contributions of oculomotor behavior and motion sensitivity to perceptual completion performance in individual infants. Young infants…
Infants' perception of transparency
Four- and 7-month-old infants' perception of transparency was investigated with computer-generated achromatic or color displays depicting a semitransparent box occluding the center of a rod. Following habituation, infants viewed test displays consisting of either a two-color rod (corresponding to the habituation display's proximal characteristics) or a solid rod (corresponding to the distal characteristics of the event depicted by the habituation…

Newborn Infants' Preference for Attractive Faces
Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described with the aim of finding whether the “attractiveness effect” results from attention to internal or external facial features, or both. Pairs of attractive and less attractive faces (as judged by adults) were shown …

Young Infants' Perception of Object Unity in Rotation Displays
Much research has been devoted to questions regarding how infants begin to perceive the unity of partly occluded objects, and it is clear that object motion plays a central role. Little is known, however, about how infants' motion processing skills are used in such tasks. One important kinetic cue for object shape is structure from motion, but its role in unity perception remains unknown. To address this issue, we presented 2‐ and 4‐month‐old inf…
Where Infants Look Determines How They See
A fundamental question of perceptual development concerns how infants come to perceive partly hidden objects as unified across a spatial gap imposed by an occluder. Much is known about the time course of development of perceptual completion during the first several months after birth, as well as some of the visual information that supports unity perception in infants. The goal of this investigation was to examine the inputs to this process. We re…
