Fourteen-month-olds selectively imitated a sub-efficient means (illuminating a lightbox by a head-touch) when this was modeled by linguistic ingroup members in video-demonstrations. A follow-up study with slightly older infants, however, could replicate this effect only in a video-demonstration context. Hence it still remains unclear whether…

An ability to detect the common location of multisensory stimulation is essential for us to perceive a coherent environment, to represent the interface between the body and the external world, and to act on sensory information. Regarding the tactile environment "at hand", we need to represent somatosensory stimuli impinging on the skin…

This study aims to examine the effect of kangaroo care on Vulnerable Infant Syndrome (VIS) in the mother. The sample group consisted of 58 preterm infants, 27 of whom were control and 31 were experimental groups. Data were collected using the question form, the Vulnerable Baby Scale (VBS), the Edinburgh Post Partum Depression Scale (EPDS), the…

Diminished response to name, a potential early marker of autism spectrum disorder (ASD), may also indicate risk for other disorders characterized by attention problems, including attention-deficit/hyperactivity disorder (ADHD). Using a familial risk design, we examined whether response to name ability at 6, 12, 18, 24, and 36 months of age…

Visual attention in complex, dynamic scenes is attracted to locations that contain socially relevant features, such as faces, and to areas that are visually salient. Previous work suggests that there is a "global shift" over development such that observers increasingly attend to faces with age. However, no prior work has tested whether…

Fragmented sleep is common in infancy. Although night awakening is known to decrease with age, in some infants night awakening is more persistent and continues into older ages. However, the influence of fragmented sleep on development is poorly known. In the present study, the longitudinal relationship between fragmented sleep and psychomotor…

The present study investigates the relation between language environment and language delay in 63 British-English speaking children (19 typical talkers (TT), 22 late talkers (LT), and 22 late bloomers (LB) aged 13 to 18 months. Families audio recorded daily routines and marked the new words their child produced over a period of 6 months. To…

This experiment tests the age at which left-to-right spatial associations found in infancy shift to culture-specific spatial biases in later childhood, for both numerical and non-numerical information. Children ages 1-5 years (N = 320) were tested within an eye-tracking paradigm which required passive viewing of a video portraying a spatial…

Saccade latency is widely used across infant psychology to investigate infants' understanding of events. Interpreting particular latency values requires knowledge of standard saccadic RTs, but there is no consensus as to typical values. This study provides standard estimates of infants' (n = 194, ages 9 to 15 months) saccadic RTs under a range of…

The development of theory of mind (ToM) in infancy has been mainly documented through studies conducted on a single age group with a single task. Very few studies have examined ToM abilities other than false belief, and very few studies have used a within-subjects design. During 2 testing sessions, infants aged 14 and 18 months old were…

Vulnerability of morphosyntactic production, including grammatical aspect, has been identified in at least some children with autism spectrum disorder (ASD) exposed to typologically different languages. However, Tovar et al. (2015) found strengths in comprehending grammatical aspect in English-exposed children with ASD, suggesting that the…

There is renewed interest in person-centered approaches to understanding the structure of temperament. However, questions concerning temperament types are not frequently framed in a developmental context, especially during infancy. In addition, the most common person-centered techniques, cluster analysis (CA) and latent profile analysis (LPA),…

Personal narrative is decontextualized talk where individuals recount stories of personal experience about past or future events. As an everyday discursive speech type, narrative potentially invites parents and children to explicitly link together, generalize from, and make inferences about representations--that is, to engage in higher-order…

Purpose: This study assesses the impact of patient clinical history on audiologists' performance when interpreting auditory brainstem response (ABR) results. Method: Fourteen audiologists' accuracy in estimating hearing threshold for 16 infants through interpretation of ABR traces was compared on 2 occasions at least 5 months apart. On the 1st…
