Variability in infant helping and sharing behaviors across the second and third years of life: Differential roles of target and socialization.

Infants can help and share in the second year of life. However, there is limited knowledge as to variability in these behaviors as a function of target (e.g., caregiver vs. unfamiliar adult) and the influence of caregiver support on infant prosocial behavior. Infants (N = 268, 124 female) at 1-2 years of age (M = 1.47, SD = .27) and again at 2-3 years of age (M = 2.48, SD = .26) participated in a helping task (with the caregiver or unfamiliar experimenter), a sharing task (with either target), and a free-play observation with their primary caregiver from which caregiver support was coded. The racial and ethnic composition of the sample consisted of 3% Asian, 10% Black, 20% Hispanic, 59% White, 1% mixed race, and 6% "other." Median family annual income was $50,000 to $59,000, and median caregiver education level was "some college." Infant helping favored caregivers at both time points. However, infant sharing did not differ by target for 1-2-year-olds, but 2-3-year-olds shared more with their caregivers than an unfamiliar experimenter. Additionally, infants' behaviors antecedent to the act of helping or sharing (e.g., latency to respond, checking behaviors, and looking duration toward the target) differed by target. Concurrent relations between caregiver support and helping and sharing were moderated by age and differed by time point. Caregiver support for 1-2-year-olds also longitudinally predicted an age-moderated relation with 2-3-year-olds' helping toward an unfamiliar experimenter. Theoretical implications for the role of socialization in the emergence of helping and sharing behaviors are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Infants' response to a mobile phone modified still-face paradigm: Links to maternal behaviors and beliefs regarding technoference.

Interruptions to parent-child interactions due to technology, or "technoference," have been correlated with a host of negative child developmental outcomes. Yet, the influence of technoference on parent-infant interactions and infant behaviors has received less attention and more experimental work is warranted. For this study, parent-infant dyads (n = 227) completed a modified still-face paradigm (SFP) using a mobile phone during the still-face phase. Infant responses were coded for positive and negative affect, object and parent orientation, self-comforting, and escape behaviors during the task. Results showed a robust still-face effect, with infants displaying increased negative affect, decreased positive affect, increased self-comforting, object orientation, and escape behaviors during the "still-face" or phone distracted phase of the paradigm and frequently failing to return to baseline during the reunion phase. Older infants (older than 9 months) likewise demonstrated higher levels of negative affect across all three phases of the paradigm relative to younger infants (less than 9 months). Parent reports of technoference behavior were related to increased object orientation for younger infants. Parental technoference behaviors were also linked to more escape behaviors for younger infants and decreased object orientation in older infants during the still-face portion of the SFP. Higher levels of technoference also appear to attenuate the negative emotional response of infants during still face. Results are discussed in relation to infants' increasing exposure to digital technology in the context of early relationships.
