Effects of Prenatal DHA Dose on Infant Visual Attention
Prenatal supplementation with docosahexaenoic acid (DHA) has been reported to improve cognitive outcomes in infancy and early childhood in some studies. Existent studies have examined the effects of some dose of DHA against a true placebo; this report is the first to describe the effects of different doses of prenatal DHA on infant visual attention at 4 and 6 months of age. In a follow‐up to a Phase III registered clinical trial (NCT02709239) des…
Commentary on the scientific rigor of Sen and Gredebäck's simulation
The operant mobile paradigm has been used to systematically characterize infant memory.In their review of the mobile literature, Sen and Gredebäck (2022) confirmed the scientific rigor of the existing procedure and found no evidence of biases in terms of p-hacking, reporting errors, or the "stopping" rule.However, based on simulation analyses they claimed that research using this paradigm "has been contaminated by methodological artifacts due to …
Introduction to Special Section
Conceptualizing Social Attention in Developmental Research
The term social attention has become widely used during the last decade, appearing within behavioral neuroscience and developmental neurocognitive literatures to characterize a variety of activities and cognitive processes that emerge in the presence of conspecifics. We provide here an overview of the current status of social attention as a construct, as reflected in its appearance in research studies, and we offer a framework for characterizing …
Separable Attentional Predictors of Language Outcome
The aim of this study was to examine the combined influences of infants' attention and use of social cues in the prediction of their language outcomes. This longitudinal study measured infants' visual attention on a distractibility task (11 months), joint attention (14 months), and language outcomes (word–object association, 14 months; MBCDI vocabulary size and multi‐word productions at 18 months of age). Path analyses were conducted for two diff…
Infant Perception and Cognition
This chapter summarizes research in the last decade on the development of perception and cognition in preverbal infants. The chapter begins by placing the current state of the field in its historical context, and covers the basic and predominant methodological techniques and paradigms used in the field. The major part of the chapter is spent summarizing progress in eight specific subtopics within the area: attention, learning, intersensory/interm…
Your Eyes Say “No,” But Your Heart Says “Yes”
Behavioral indices (e.g., infant looking) are predominantly used in studies of infant cognition, but psychophysiological measures have been increasingly integrated into common infant paradigms.The current study reports a result in which behavioral measures and physiological measures were both incorporated in a task designed to study infant number discrimination.Seven-month-old infants were habituated to several sets of stimuli varying in object t…
What Habituates in Infant Visual Habituation? A Psychophysiological Analysis
Despite the use of visual habituation over the past half century, relatively little is known about its underlying processes. We analyzed heart rate (HR) taken simultaneous with looking during infant‐controlled habituation sessions collected longitudinally at 4, 6, and 8 months of age with the goal of examining how HR and HR‐defined phases of attention change across habituation. There were four major findings. First, the depth and topography of de…
Habituation revisited
Visual processing and infant ocular latencies in the overlap paradigm
Young infants have repeatedly been shown to be slower than older infants to shift fixation from a midline stimulus to a peripheral stimulus. This is generally thought to reflect maturation of the neural substrates that mediate the disengagement of attention, but this developmental difference may also be attributable to young infants' slower processing of the midline stimulus. This possibility was tested with 3- and 7-month-old infants in 2 experi…
The Developmental Course of Habituation in Infancy and Preschool Outcome
A longitudinal sample of 226 infants were tested monthly on habituation and novelty preference tasks, augmented with simultaneous heart rate recording from 3 to 9 months of age. Infants were then administered the Bayley Scales of Infant Development II (BSID) and MacArthur Communicative Development Inventory (MCDI) at 12, 18, and 24 months. Prior findings regarding the decline in look duration with age were replicated. Age‐based factors were extra…
Developmental Changes in Infant Attention to Dynamic and Static Stimuli
This study examined 4‐ and 6‐month‐olds' responses to static or dynamic stimuli using behavioral and heart‐rate‐defmed measures of attention. Infants looked longest to dynamic stimuli with an audio track and least to a static stimulus that was mute. Overall, look duration declined with age to the different stimuli. The amount of time spent in sustained attention at 4 months, but not at 6 months, was related to stimulus discrimination. These resul…
The Development of Visual Attention in Infancy
Over the past decade, the study of attention in infancy has seen dramatic progress. This review delineates four attentional functions (alertness, spatial orienting, attention to object features, and endogenous attention) that are relevant to infancy and uses these functions as a framework for summarizing the developmental course of attention in infancy. Rudimentary forms of various attentional functions are present at birth, but each of the funct…
Temporal Sequence of Global‐Local Processing in 3‐Month‐Old Infants
In 3 experiments, the temporal processing sequence of local and global visual properties was investigated with 3‐month‐old infants. Across the experiments, a global pattern was discriminated under conditions of less familiarization than was necessary for local elements to be discriminated, thus indicating a global precedence in the sequence of visual processing at 3 months of age. Patterns of discrimination were also observed to vary as a functio…

Pitch perception in young infants
The critical period concept
The concept of periods in postnatal behavioral development is reviewed. Evidence on the criteria and characteristics of critical period phenomena is considered with respect to endogenous and exogenous influences; methodology of critical period research is described and evaluated; and conceptual issues and problems are discussed in light of past attempts at subclassification of the field and recovery of function as a refutation of the critical per…
