The extant literature on the use of autonomy support during caregiver–child conversations has focused primarily on conversations about fun, shared experiences, with limited consideration of unshared experiences or attention toward the role of conversation context. The present study examined how autonomy support, conversation context, and child age interact to predict 3-to-5-year-old children's disclosure of accurate information when discussing an unshared past event with their caregiver and an experimenter. Dyads (N = 111) were recruited from two locations (Miami, Florida and Orange County, California) by research recruitment firms. Children completed a standardized activity alone and then discussed the activity with their caregiver. The context of the discussion was manipulated so that dyads focused on either accumulating facts (Fact condition) or having fun (Fun condition). Afterward, children discussed the activity with a neutral interviewer. Caregivers in the fact condition were less autonomy supportive when discussing the activity than those in the fun condition. During the caregiver–child interview, caregiver autonomy support was negatively associated with children's disclosure of correct event details for those in the fun condition only. Caregiver autonomy support was negatively associated with children's correct details during the experiment–child interview across both context conditions. While older children provided more correct details during both interviews, there were no other age-related effects. These results demonstrate that conversation context moderates the link between autonomy support and children's autobiographical memory performance. Past contradictory findings in the field are discussed in light of these results. Public Significance Statement: The present study provides unique insight into the role caregiver autonomy support plays in eliciting accurate descriptions of the past from preschool-aged children across multiple contexts. The results of this experiment emphasize the importance of considering contextual factors when researching caregiver–child conversations and children's autobiographical memory.

While the behavioral and physiological impacts of nursery rearing in laboratory-housed infant monkeys have been well characterized, to date no studies have examined the impact on nonhuman primate dams of their infants being removed for rearing in the nursery. Despite the lack of evidence on the topic, anti-animal research groups often cite mother-infant separation and infant nursery rearing (NR) as a welfare concern for laboratory monkey mothers. As such, important policy decisions regarding research activities may result without adequate evidence. Therefore, we designed this study to examine behavioral and hormonal responses in laboratory monkey dams, who were part of independent long-term longitudinal studies, in response to their infants being NR or mother-peer-reared (MPR). We assessed social, self-care, environmental exploration, and abnormal behaviors for 30 days before and 30 days after parturition in rhesus monkey dams (Macaca mulatta , N=49). Infants were randomly assigned to be either NR (N = 27) or MPR (N = 22). We also analyzed hair samples for cortisol concentrations three times across the study period (Pregnancy, Neonatal Period, Peak Lactation). Dams of NR infants showed no gross behavioral differences relative to dams of MPR infants (all p's>0.05). Dams of MPR infants showed expected increases in social grooming and social contact, and concomitant decreases in foraging and locomotion, in the 30 days post-partum compared to the 30 days pre-partum (p<0.01). Dams whose infants were NR or MPR showed no differences in hair cortisol concentrations across the study period (p>0.05). We conclude that, with respect to the behavioral and endocrine measures we assessed, nursery rearing of their infants is not detrimental to the welfare of laboratory-housed macaque dams. • The behavior and cortisol of laboratory-housed rhesus monkey dams was studied. • Dams' infants were mother-peer-reared (MPR) or nursery-reared (NR). • Dams were studied for 30 days prior to and 30 days after parturition. • Dams did not differ in global behavioral or hair cortisol profiles. • Infant nursery-rearing does not pose a welfare threat to rhesus monkey dams.

Alpha status may lead to physiological changes that enhance secondary sexual characteristics, which may serve as competitive signals to conspecific males, sexual signals to females, or possibly a combination of both. Here, we report measurements of secondary sexual characteristics in captive dominant and subordinate male tufted capuchin monkeys (Sapajus apella) with varying access to females. An adult male (who had previously been subordinate while housed with other males) was paired with an adult female. This male–female pair was introduced into a room that housed three other male–male pairs with stable hierarchy arrangements. We analyzed weight, body measurements, facial photographs, and hair cortisol before, during, and after introducing a female into the room. While there were no differences in weight or measurements between alphas and subordinates without physical access to the female prior to or during the female's presence, we found that direct access to the female resulted in dramatic changes in facial appearance, body size, and testicular volume in the male who was paired with her. Overall, we found little evidence to suggest that alpha males advertise their status within all‐male groups via sexual secondary characteristics. However, direct physical access to females appears to trigger the development of such characteristics in alpha males. It remains of continued interest to identify the endocrine mechanisms responsible for the development, and possible loss, of secondary sexual characteristics. [ABSTRACT FROM AUTHOR] more...

Researchers have identified cultural differences in caregiver beliefs about the functions of parent–child reminiscing. However, this work has largely been limited to comparisons between Asian or Asian American and European American caregivers discussing autobiographical events, broadly. In the present study, 365 caregivers of 3- to 12-year-old children from four U.S. subcultures (African, Asian, European, and Hispanic/LatinX) reported about the functions of discussing positive and negative past events with their child, and about their collectivist values. Overall, positive events were discussed more often than negative events and all reminiscing functions were endorsed more strongly for positive events. European Americans endorsed directive functions for positive events least of the three primary functions, and endorsed them less than the other three subcultural groups. All four subculture groups endorsed directive functions equally and more strongly than other functions when discussing negative events. More collectivist attitudes predicted stronger endorsement of all conversation functions except directive functions for negative events. This research is poised to expand our understanding of how caregivers from different subcultural groups, and with different culture-based values, may attempt to shape their children's worldview through reminiscing and how the functions caregivers emphasise shift depending on the valence of the event under discussion.

Participation in social skills therapy (SST) facilitates cognitive functioning in children with developmental disabilities. The present pilot study examined whether participation in SST was associated with enhanced encoding and 1-month delayed recall in children with Down syndrome (DS). Children were presented with novel three-step event sequences in an elicited imitation procedure. Immediate imitation was permitted as an index of encoding; long-term memory was assessed 1 month later. Parents completed questionnaires inquiring about children's participation in SST. Participation in SST was associated with enhanced encoding of temporal order information and 1-month delayed recall of individual target actions. In addition, encoding mediated the relation between group and 1-month delayed recall. The conducted research indicates that involvement in SST may be beneficial for children with DS despite their noted strengths in imitation and social learning. As such, additional experimental work is warranted to determine causality. [ABSTRACT FROM AUTHOR] more...

Emotion regulation (ER) is a multifaceted construct, involving behavioral, cognitive, and physiological processes. Although autonomic coordination is theorized to play a crucial role in adaptive functioning, few studies have examined how different individual and contextual factors together may contribute to such coordination. This study examined the joint influences of narrative processing and emotional negativity/lability (N/L) traits on the coordination of the sympathetic and parasympathetic nervous systems in a sample of 112 children, ages 8–12 years (Mage = 10.15 years, SD = 1.33). Children completed a stress‐induction task followed by an interview about the task. Children's trait‐level N/L was assessed via parent‐report on the Emotion Regulation Checklist. Narrative processing was assessed and coded based on children's narrative accounts of the event (i.e., causal coherence, overall emotional tone). Indexes of sympathetic (skin conductance response, SCR) and parasympathetic (respiratory sinus arrhythmia, RSA) functioning were derived from physiological data obtained during the interview. Results revealed that children's trait‐level N/L and narrative processing of the stressful event interacted to predict the RSA–SCR correlation. Specifically, children who were high on either N/L or narrative causal coherence, but not both, demonstrated significant RSA–SCR correlation. Similarly, children with high N/L and negative‐to‐neutral narratives, as well as those with low N/L and neutral‐to‐positive narratives, exhibited significant RSA–SCR correlation. This work provides empirical evidence that narrative processing and trait N/L, together with RSA–SCR correlation, work in tandem to regulate emotional arousal. This study examined the interactive roles of individual and contextual factors in association with autonomic coordination in ER. Children's trait‐level negativity/lability and narrative processing (i.e., causal coherence, the overall emotional tone) interacted to predict sympathetic and parasympathetic coordination. Findings empirically support that narrative processing and trait N/L, together with RSA–SCR correlation, work in tandem to regulate emotional arousals. [ABSTRACT FROM AUTHOR] more...

Both human and nonhuman primate adults use infant-directed facial and vocal expressions across many contexts when interacting with infants (e.g., feeding, playing). This infant-oriented style of communication, known as infant-directed speech (IDS), seems to benefit human infants in numerous ways, including facilitating language acquisition. Given the variety of contexts in which adults use IDS, we hypothesized that IDS supports learning beyond the linguistic domain and that these benefits may extend to nonhuman primates. We exposed 2.5-month- old rhesus macaque infants (N = 15) to IDS, adult-directed speech (ADS), and a non-social control (CTR) during a video presentation of unrelated stimuli. After a 5-or 60-minute delay, infants were shown the familiar video side-by- side with a novel video. Infants exhibited a novelty preference after the 5-minute delay, but not after the 60-minute delay, in the ADS and CTR conditions, and a novelty preference in the IDS condition only after the 60-minute delay. These results are the first to suggest that exposure to IDS affects infants’ long-term memory, even in non-linguistic animals. [ABSTRACT FROM AUTHOR] more...

• Caregivers use a unique approach to talk about unshared events relative to shared events. • Caregivers say less when discussing an unshared event with children. • Caregivers modify past talk somewhat based on whether they are focused on gather facts or having fun. • Individual characteristics and caregivers' conversation styles predict children's recall. Caregiver-child dyads discuss unshared experiences on a daily basis. Yet, most research explores how dyads discuss shared experiences, with limited examination of how caregivers elicit information when discussing unshared experiences. The present study examined how caregivers modify their narrative style across the two conversation types, while also considering conversation goal and child recall. Eighty-six dyads discussed a shared past experience and unshared play activity experienced by the child. Caregivers were randomly assigned to discuss the play activity with the goal of gathering facts or having fun. Caregivers varied their conversation style when discussing the unshared event relative to the shared event and modified their conversation style somewhat depending on the assigned conversation goal. Caregivers' conversation styles and child individual characteristics predicted children's provision of correct information about the activity. Results preliminarily suggest caregivers use a unique approach to talk about unshared relative to shared events. [ABSTRACT FROM AUTHOR] more...

Background: Research conducted with typically developing (TD) infants and children generally indicates that better habitual sleep and sleep after learning are related to enhanced memory. Less is known, however, about associations between sleep and recall memory in children with Down syndrome (DS).Aims: The present study was conducted to determine whether parent-reported sleep problems were differentially associated with encoding, 1-month delayed recall memory, and forgetting over time in children with DS and those who were TD.Methods and Procedures: Ten children with DS (mean age = 33 months, 5 days) and 10 TD children (mean age = 21 months, 6 days) participated in a two-session study. At each session, recall memory was assessed using an elicited imitation paradigm. Immediate imitation was permitted at the first session as an index of encoding, and delayed recall was assessed 1 month later. In addition, parents provided demographic information and reported on child sleep problems.Outcomes and Results: Although parents did not report more frequent sleep problems for children with DS relative to TD children, regression-based moderation analyses revealed that more frequent sleep problems were associated with increased forgetting of individual target actions and their order by children with DS. Evidence of moderation was not found when examining encoding or delayed recall.Conclusions and Implications: Although group differences were not found when considering parent-reported sleep problems, more frequent sleep problems were positively associated with increased forgetting by children with DS relative to those who were TD. Although future experimental work is needed to determine causality, these results suggest that improved sleep in children with DS might reduce forgetting, ultimately improving long-term recall memory.

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother-infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex-differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the "lactational programming" hypothesis on the impact of maternal-origin hormones ingested via milk. [ABSTRACT FROM AUTHOR] more...

The primary goal of the present research was to examine associations between sleep quality and the subjective experience of autobiographical events. In an online study, 141 university students reported on past events that varied by valence (positive or negative) and temporality (most significant or from the previous 2 weeks); they also completed measures of sleep quality and depression. Relative to participants with good sleep quality, participants with poor sleep quality thought more about their negative experiences, reported negative events that occurred more frequently, and used more negative emotion words when describing recent negative events. In some instances, depressive symptoms mediated the relation between sleep quality and elements of autobiographical reports. Future experimental work should examine the directionality of these effects, with the ultimate goal of improving sleep quality, mental health, and the manner in which individuals discuss and make meaning of their negative life events.
