We hypothesized that infants whose parents provide more bids for joint attention will display a more complex neural response when viewing social scenes. Sixty‐one 8‐month‐old infants underwent electroencephalography (EEG) while viewing videos of joint‐ and parallel‐play and participated in a free play interaction. EEG data was analyzed using multiscale entropy, which quantifies neural variability. Free play interactions assessed parent alternating gaze, a behavioral mechanism for directing attention to environmental cues. We found a significant positive association between parent alternating gaze and neural entropy in frontal and central regions.

This study addressed these gaps by: (1) examining the differential effectiveness of maternal regulatory attempts (MRAs; behavioral strategies initiated by mothers to assist infants with regulating emotional states) in reducing 12- to 24-month-old infants' frustration during a toy removal task; and (2) assessing whether maternal mind-mindedness (mothers' attunement to their infant's mental state) predicted mothers' selection of MRAs. Multilevel modeling revealed that distraction and control were the most effective MRAs in reducing infant negative affect across 5-s intervals (<i>N</i> = 82 dyads; <i>M</i> infant age = 18 months; 45 females). Greater use of non-attuned mind-related speech predicted less engagement in effective MRAs, supporting a link between caregivers' socio-cognitive skills and provision of in-the-moment regulation support. These findings highlight the value of considering caregiver regulatory behaviors as a target for elucidating how maternal socialization of emotion regulation occurs in real-time.

Specifically, we consider how prenatal experiences characterized in the DOHaD model impact two key neurobiological mechanisms of sensitive/critical periods for adapting to and learning from the postnatal environment. We draw from both animal and human research to summarize the current state of knowledge on how particular prenatal substance exposures (psychoactive substances and heavy metals) and nutritional profiles (protein-energy malnutrition and iron deficiency) each differentially impact brain circuits' excitation/GABAergic inhibition balance and myelination. Finally, we highlight new research directions that emerge from this integrated framework, including testing how prenatal environments alter sensitive/critical period timing and learning and identifying potential promotional/buffering prenatal exposures to impact postnatal sensitive/critical periods.

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 tested diverse lexical contrasts and have not tested beyond 30 months. To specify the developmental trajectory over a broader age range, we extended a prior study (Quam & Swingley, 2010), in which 30-month-olds and adults disregarded pitch changes, but attended to vowel changes, in newly learned words. Using the same phonological contrasts, we tested 3- to 5-year-olds, 24-month-olds, and 18-month-olds. The older two groups were tested using the language-guided-looking method. The oldest group attended to vowels but not pitch. Surprisingly, 24-month-olds ignored not just pitch but sometimes vowels as well—conflicting with prior findings of phonological constraint at 24 months. The youngest group was tested using the Switch habituation method, half with additional phonetic variability in training. Eighteen-month-olds learned both pitch-contrasted and vowel-contrasted words, whether or not additional variability was present.
