We tested 6- and 8-month-old White and non-White infants (N = 53 total, 28 girls) from Northern California in a visual search task to determine whether a unique item in an otherwise homogeneous display (a singleton) attracts attention because it is a unique singleton and "pops out" in a categorical manner, or whether attention instead…

Abstract Labeling promotes infants' object categorization even when labels are rare. By 2 years, infants engage in "semi-supervised learning" (SSL), integrating labeled and unlabeled exemplars to learn categories. However, everyday learning contexts pose substantial challenges for infants' SSL. Here, two studies (n = 74, 51% female, 62%…

According to the Ecological Model, positive parenting depends on three factors: psychosocial context, the children's needs and parental competences. This cross-sectional study analyzes parental competences, perception of efficacy and parenting satisfaction, among Spanish fathers and mothers with young children aged 0-3 years, and examines their…

The study aims to clarify the relation between maternal sensitivity and infant attachment security during the first two years of life. A systematic search has been carried out in six databases (Medline, PsycINFO, Web of Science, Science Direct, Scopus and Psychology and Behavioural) between January 2010 and February 2023. The terms used for the…

The ability to predict upcoming events is essential in infancy because it enables babies to process information optimally and have successful goal-directed interactions with their environment. In this article, we examine how infants generate predictions in perception, cognition, and action, and address whether and how their predictions are…

This article considers the related concepts of 'rehearsal' [Harney, Stefano, and Fred Moten. 2013. "The Undercommons: Fugitive Planning & Black Study." Brooklyn: Minor Compositions] and 'catastrophe' [Stengers, Isabelle. 2015. "In Catastrophic Times: Resisting the Coming Barbarism." Translated by Andrew Goffey. London: Open…

While adult studies show that consonants are more important than vowels in lexical processing tasks, the developmental trajectory of this consonant bias varies cross-linguistically. This study tested whether British English-learning 11-month-old infants' recognition of familiar word forms is more reliant on consonants than vowels, as found by…

Children's fuzziness leads to increased variance in the data, data loss, and high dropout rates in developmental studies. This study investigated the importance of 20 factors on the person (child, caregiver, experimenter) and situation (task, method, time, and date) level for the data quality as indicated via the number of valid trials in 11…

Crawling is considered an important motor skill for infants. Although infants show variations in their crawling, the association between crawling variations and subsequent development is unexplored. This study investigates the difference in amount of crawling variation between infants with and without subsequent developmental delays. This…

Growing up with multiple siblings might negatively affect language development. This study examined the associations between birth order, sibling characteristics and parent-reported vocabulary size in 6163 Norwegian 8- to 36-month-old children (51.4% female). Results confirmed that birth order was negatively associated with vocabulary, yet…

Reach-to-grasp behavior is a key developmental milestone in infants, involving coordinated actions such as arm transport, hand pre-shaping, and hand opening and closing. Vision guides the development of these skills, and delays in visual input can impact infants with early visual impairments. However, the effects of a congenital visual impairment…

Purpose: Previous studies of early speech acquisition have established characteristics of phonemes and syllable structures produced by young children. Fewer studies compared patterns in children's within-word phoneme sequences of the target words with their actual productions. Additionally, studies of consonant sequences are more frequently…

The Sensory Integration Infant Routines Questionnaire (SIIRQ) is designed to identify sensory integration difficulties through observation of participation in infant co-occupations. Identifying sensory integration and participation issues at an early age is of utmost importance given that these difficulties can affect many areas in the child's…

The recommendation to introduce shared book reading during the child's first year of life is widely acknowledged. While prior research has focused on the benefits for children, recent studies instead examine the impact on the reader. Studies have found a positive effect on parenting skills and parental well-being. Further, parents express that the…

Visual attention develops rapidly across the first postnatal year, from reflexive eye movements driven by low-level stimulus properties to increasingly voluntary eye movements influenced by higher-order factors. To test the hypothesis that development reflects guidance by increasingly abstract features, we used representational similarity analysis…
