Yes, no, maybe so: Caregiver autonomy support, conversation context, and children's memory performance.

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. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Effects of dominance and female presence on secondary sexual characteristics in male tufted capuchin monkeys (Sapajus apella).

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.

Subcultural, ideological, and valence-based differences in caregiver reminiscing functions.

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 is Associated With Enhanced Recall Memory by Children With Down Syndrome: An Exploratory Study.

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.

Sleep problems and recall memory in children with Down syndrome and typically developing controls.

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.

Who's my little monkey? Effects of infant-directed speech on visual retention in infant rhesus macaques.

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.

Sex and rank affect how infant rhesus macaques look at faces.

We investigated how differences in infant sex and mothers' dominance status affect infant rhesus macaques' (Macaca mulatta) interest in visually exploring emotional facial expressions. Thirty-eight infants were presented with animated avatars of macaque facial expressions during the first month of life. Sons of high-ranking mothers looked more at faces, especially the eye region, than sons of low-ranking mothers, but no difference in looking duration was found for daughters. Males looked significantly more at eyes than females, but this effect was reversed in infants who were reared without mothers in a primate nursery facility. In addition, in mother-infant interactions, mothers of sons were more likely to gaze at their infant's face compared to mothers of daughters. Combined with previous research indicating that rhesus macaque mothers interact differently with infants based on their own rank and infant's sex, these results support the view that social experiences shape early face preferences in rhesus macaques.
