Developmental change in English‐learning children's interpretations of salient pitch contours in word learning Infancy (IF 2.459) Pub Date : 2024-02-29 Carolyn Quam, Daniel Swingley
To efficiently recognize words, children learning an intonational language like English should avoid interpreting pitch‐contour variation as signaling lexical contrast, despite the relevance of pitch at other levels of structure. Thus far, the developmental time‐course with which English‐learning children rule out pitch as a contrastive feature has been incompletely characterized. Prior studies have

Early gesture use predicts children’s language development in South Korea: New evidence supporting the cross‐cultural importance of pointing Infancy (IF 2.459) Pub Date : 2024-02-26 So Yeon Shin, Meredith L. Rowe, Hyun Suk Lee
Research in the U.S. and other Western countries shows that children’s early gesture use, which starts prior to verbal communication, is an important predictor of children’s later language development. Despite increasing efforts to study gesture use in diverse contexts, most of our knowledge on the role of gesture is largely based on populations of Western countries. In this study, we add to the growing

Touch and look: The role of affective touch in promoting infants' attention towards complex visual scenes Infancy (IF 2.459) Pub Date : 2024-01-05 Laura Carnevali, Letizia Della Longa, Danica Dragovic, Teresa Farroni
In a complex social environment, stimuli from different sensory modalities need to be integrated to decode communicative meanings. From very early in life, infants have to combine a multitude of sensory features with social and affective attributes. Of all senses, touch constitutes a privileged channel to carry affective-motivational meanings and foster social connection. In the present study, we investigate

The role of local meaning in infants' fixations of natural scenes Infancy (IF 2.459) Pub Date : 2024-01-06 Lisa M. Oakes, Taylor R. Hayes, Shannon M. Klotz, Katherine I. Pomaranski, John M. Henderson
As infants view visual scenes every day, they must shift their eye gaze and visual attention from location to location, sampling information to process and learn. Like adults, infants' gaze when viewing natural scenes (i.e., photographs of everyday scenes) is influenced by the physical features of the scene image and a general bias to look more centrally in a scene. However, it is unknown how infants'

Longitudinal associations between parents' prosocial behavior and media use and young children's prosocial development: The mediating role of children's media use Infancy (IF 2.459) Pub Date : 2023-12-30 Laura M. Padilla-Walker, Katey Workman, Anna Calley, Sarah Ashby, Hailey G. Holmgren, Corinne Archibald, Ashley M. Fraser, Sarah M. Coyne
Research has found that media is associated with children's prosocial behavior (PB) from an early age, and that parents play a key role in children's media use and behavior. However, few studies explore these relations as early as infancy while also controlling for well-established predictors of PB (e.g., empathic concern). Thus, the present study examined longitudinal associations between parents'

What are the roots of this early preference? We assess the extent to which it is due to it being a vocal sound, a natural sound, and a familiar sound through a meta-analytic approach, classifying experiments as a function of whether they

The context of infants' giving gestures in mother-infant dyads: Typical giving gestures and those contingent on exploration and play Infancy (IF 2.459) Pub Date : 2023-02-03 Edna Orr, Gabriela Kashy Rosenbaum
This study aimed to focus on a niche that has not yet been investigated in infants' gesture studies that is the effect of the prior context of one specific gestural behavior (gives) on maternal behavior. For this purpose, we recruited 23 infants at 11 and 13 months of age yielded 246 giving gesture bouts that were performed in three contexts: typical when the object was offered immediately, contingent

Infants use contextual memory to attend and learn in naturalistic scenes Infancy (IF 2.459) Pub Date : 2023-02-01 Kristen Tummeltshammer, Dima Amso
Infants encounter new objects and learn about object features in relation to a rich and detailed visuospatial context. Using a contextual cueing task, recent work showed that 6- and 10-month-old infants search more efficiently for target objects in repeated rather than novel visuospatial contexts (i.e., arrays of shapes on a blank background). Here, we investigate whether infants' sensitivity to visuospatial
