RESUMO
The progression from crawling to walking in infancy is associated with changes in infant language development. One possible explanation for such change is the infant's language environment. Prior research indicates that caregivers use more action directives with walking infants compared to crawling infants, but the relations of such parental speech with infant vocabulary is unknown. Here, we present findings from day-long home audio recordings (Study 1) and laboratory observations (Study 2) of same-aged crawling and walking infants to explore how caregiver language, specifically action directives, were associated with parent reported infant vocabulary size. Findings in both studies indicated that caregiver action directives were associated with crawling, but not walking infants' receptive vocabulary sizes. Specifically, action directives about objects occurring when the infant and caregiver were not jointly engaged were associated with higher receptive vocabulary scores for crawling infants, but no such pattern was found for walking infants. The replication of results in distinct samples with different research methodologies strengthens the findings. Taken together, these studies demonstrate that caregiver social engagement specific to infant motoric development is related with infant language learning.

The valid assessment of vocabulary development in dual-language-learning infants is critical to developmental science. We developed the Dual Language Learners English-Spanish (DLL-ES) Inventories to measure vocabularies of U.S. English-Spanish DLLs. The inventories provide translation equivalents for all Spanish and English items on Communicative Development Inventory (CDI) short forms; extended inventories based on CDI long forms; and Spanish language-variety options. Item-Response Theory analyses applied to Wordbank and Web-CDI data (n = 2603, 12-18 months; n = 6722, 16-36 months; half female; 1% Asian, 3% Black, 2% Hispanic, 30% White, 64% unknown) showed near-perfect associations between DLL-ES and CDI long-form scores. Interviews with 10 Hispanic mothers of 18- to 24-month-olds (2 White, 1 Black, 7 multi-racial; 6 female) provide a proof of concept for the value of the DLL-ES for assessing the vocabularies of DLLs.

OBJECTIVES: Communication difficulties are inevitable when individuals interact with members of a different culture. The experience of such communication barriers may be particularly salient for those from immigrant families who need to navigate multiple cultures. Youth from immigrant families are known to serve as cultural brokers to help their families navigate communication with those in the host culture. Most brokering research has examined language brokering (i.e., interpreting language for others). An unstudied brokering process and the focus of the present research is emotion brokering: the interpretation of emotion norms for others. In this investigation, we examined the occurrence of emotion brokering for close family members in a sample of Latinx college students. METHOD: We conducted an exploratory survey to identify situations where participants perceived intercultural emotion-based misunderstandings and reported emotion brokering (Study 1). We then employed a more focused survey to further understand the contexts in which individuals brokered emotions (Study 2). RESULTS: Results revealed that many participants encountered intercultural emotion-based misunderstandings and experienced brokering emotions (Studies 1 and 2). Furthermore, the findings illustrated the typical contexts and emotions involved in the emotion brokering experience. CONCLUSIONS: The findings provide insight into a distinct form of cultural brokering. In addition, findings illustrate how cultural variation in emotion impacts daily social interactions.

RESUMO
Infants use statistical information in their environment, as well as others' emotional communication, to understand the intentions of social partners. However, rarely do researchers consider these two sources of social information in tandem. This study assessed 2-year-olds' attributions of intentionality from non-random sampling events and subsequent discrete emotion reactions. Infants observed an experimenter remove five objects from either the non-random minority (18%) or random majority (82%) of a sample and express either joy, disgust, or sadness after each selection. Two-year-olds inferred the experimenter's intentionality by giving her the object that she had previously selected when she expressed joy or disgust after non-random sampling events, but not when she expressed sadness or sampled at random. These findings demonstrate that infants use both statistical regularities and discrete emotion communication to infer an agent's intentions. In particular, the present findings show that 2-year-olds infer that an agent can intentionally select a preferred or an undesired object from a sample as a function of the discrete emotion. Implications for the development of inferring intentionality from statistical sampling events and discrete emotion communication are discussed.

Infants readily re-enact others' intended actions during the second year of life. However, the role of emotion in appreciating others' intentions and how this understanding develops in infancy remains unstudied. In the present study, 15- and 18-month-old infants observed an experimenter repeatedly attempt but fail to produce a target action on an object and express either frustration or neutral affect after each attempt. Analyses of infants' responses revealed that 18-month-old infants, but not 15-month-olds, produced more target actions in the frustration condition than the neutral condition. These results suggest that infants use emotional communication to disambiguate and re-enact others' intended actions and that this ability develops in the second year of life.

Identifying momentary influences on ambulatory blood pressure (ABP) will help explain ABP variability; however, most research only examines aggregate ABP at the between-person level. This study used within-person methods to examine whether affective dimensions-valence and arousal-differentially predicted momentary ABP levels. A community sample (n = 39) wore an ABP cuff that took BP measurements every 20 min for 24 h. At each measurement, participants reported levels of valence and arousal on electronic diaries. Multilevel modeling was used to examine the effects of momentary and person-averaged levels of valence and arousal on ABP. Greater momentary negative valence and arousal predicted higher systolic BP compared to more positive or lower arousal assessments; higher averaged levels of arousal predicted higher DBP. The results suggest the independence of the effects of valence and arousal on BP. These findings have important implications for designing interventions to lower ABP.

Emotion understanding involves appreciating the significance of the relational context; the "aboutness" of the emotion. This study examined how children labeled emotions and described relational elements of discrete emotion contexts. Preschool children (3.5-year-olds, n = 22; 4.5-year-olds, n = 23) described images of 5 emotion contexts (anger, sadness, disgust, fear, and joy). Researchers assessed children's (1) correct labeling of discrete emotions, and (2) differential mentioning of the emoter (person displaying the emotion) and the referent (the elicitor of the emotion) across discrete emotions. Children's pattern of accurately labeling discrete emotions was similar to prior research, with both age groups correctly labeled anger, sadness, and joy more often than disgust or fear. Novel to the present study, we found that older children differentially highlighted emotional elements (i.e., the emoter, the referent) when describing discrete emotion contexts. Specifically, 4.5-year-olds emphasized the emoter more when describing anger, sadness, and joy than fear and disgust contexts, and mentioned the referent more in disgust, fear, and joy than anger and sadness contexts. Differential emphasis of relational elements was not observed for 3.5-year-olds. These findings highlight the importance of examining children's appreciation of relational contexts and indicate important differences in how children differentially emphasize relational elements when viewing discrete emotion contexts. Potential developmental mechanisms, opportunities for further empirical research, and implications for emotion theory are discussed.

RESUMO
Valence is central to the experience of emotion. However, to the detriment of affective science, it is often ill-defined and poorly operationalized. Being more precise about what is meant by valence would make for more readily comparable emotion stimuli, methodologies, and results, and would promote consideration of the diversity, complexity, and function of discrete emotions. This brief review uses prior literature and an informal survey of affective scientists to illustrate disagreements in conceptualizing valence. Next, we describe issues of valence in affective science, particularly as they pertain to the emotion process, the functions of emotion, and precision in empirical research. We conclude by providing recommendations for the future of valence in affective science.
RESUMO
Parents play an important role in socializing children's emotion understanding. Previous research shows that parents emphasize different aspects of emotion contexts depending on the discrete emotion. However, there is limited research on how parents and children discuss self-conscious emotions, such as embarrassment, guilt, and shame, and what socialization practices parents employ to elicit children's talk about these emotions. In this study, children (N = 166, 78 females, 88 males) ages 2-3 years (M = 2.46, SD = 0.26) and their parents (65.5% White, 10.2% Black, 17.5% Hispanic, 2.4% Asian American, and 5.4% other) from a large city in the Western United States discussed a wordless storybook depicting different female and male characters experiencing self-conscious emotions (embarrassment, guilt, shame, awe, and pride). Parents' and children's emotion talk and parents' questions were coded from their conversations about each emotion scenario and subsequently analyzed by discrete emotion, child gender, and the depicted character's gender. Parents and children differentially focused on different aspects of each self-conscious emotion as a function of discrete emotion and picture gender, and elements of children's talk about self-conscious emotions were related to children's expressive language and age. Additionally, parents' emotion talk and questions about emotions were directly related to children's emotion talk, even after controlling for children's age, expressive language, and parental education. Taken together, these findings suggest that parent-child emotion conversations may be one context that facilitates the development of children's understanding of self-conscious emotions.

There is ongoing debate as to whether emotion perception is determined by facial expressions or context (i.e., non-facial cues). The present investigation examined the independent and interactive effects of six emotions (anger, disgust, fear, joy, sadness, neutral) conveyed by combinations of facial expressions, bodily postures, and background scenes in a fully crossed design. Participants viewed each face-posture-scene (FPS) combination for 5 s and were then asked to categorize the emotion depicted in the image. Four key findings emerged from the analyses: (1) For fully incongruent FPS combinations, participants categorized images using the face in 61% of instances and the posture and scene in 18% and 11% of instances, respectively; (2) postures (with neutral scenes) and scenes (with neutral postures) exerted differential influences on emotion categorizations when combined with incongruent facial expressions; (3) contextual asymmetries were observed for some incongruent face-posture pairings and their inverse (e.g., anger-fear vs. fear-anger), but not for face-scene pairings; (4) finally, scenes exhibited a boosting effect of posture when combined with a congruent posture and attenuated the effect of posture when combined with a congruent face. Overall, these findings highlight independent and interactional roles of posture and scene in emotion face perception. Theoretical implications for the study of emotions in context are discussed.

RESUMO
Adolescent mothers experience poorer sleep than adult mothers, and Latina adolescent mothers are at greater risk of postpartum depression compared with other racial/ethnic groups. However, social support may be protective against the negative effects of poor sleep in this population. The current study examined (1) associations between the quality and quantity of Latina adolescent mothers' sleep and mental health (depressive symptoms and anxiety), and (2) whether social support buffered the effects of poor sleep on mental health. A sample of Latina adolescent mothers (N = 84) from an agricultural region in the United States reported on their sleep duration/quality, social support from family, friends, and significant others, and their depressive and anxiety symptoms. Results showed that adolescent mothers reported poorer sleep than pediatric recommendations, and poorer sleep quality was associated with greater depressive and anxiety symptoms. Interestingly, when adolescent mothers reported better sleep, they had fewer depressive symptoms in the context of high support from friends compared with low support from friends. Sleep is important for mental health in Latina adolescent mothers, and better sleep combined with strong social support has positive associations with mental health in this population. Findings hold implications for improving mental health in adolescent mothers.
RESUMO
The collection of articles presented by Pollak, Camras, and Cole (2019) provides a stimulating survey of the current state of research on emotional development. However, the special issue also makes apparent the need for defining the construct of interest. Definitions of emotions guide how researchers deal with fundamental theoretical and methodological issues in emotion research. In this commentary, we contrast 2 views of emotion: the structuralist and functionalist perspectives. We illustrate the consequences of each view for the design and interpretation of empirical research and highlight benefits of adopting a functionalist perspective on emotional development.

This study used LENA recording devices to capture infants' home language environments and examine how qualitative differences in adult responding to infant vocalizations related to infant vocabulary. Infant-directed speech and infant vocalizations were coded in samples taken from daylong home audio recordings of 13-month-old infants. Infant speech-related vocalizations were identified and coded as either canonical or non-canonical. Infant-directed adult speech was identified and classified into different pragmatic types. Multiple regressions examined the relation between adult responsiveness, imitating, recasting, and expanding and infant canonical and non-canonical vocalizations with caregiver-reported infant receptive and productive vocabulary. An interaction between adult like-sound responding (i.e., the total number of imitations, recasts, and expansions) and infant canonical vocalizations indicated that infants who produced more canonical vocalizations and received more adult like-sound responses had higher productive vocabularies. When sequences were analyzed, infant canonical vocalizations that preceded and followed adult recasts and expansions were positively associated with infant productive vocabulary. These findings provide insights into how infant-adult vocal exchanges are related to early vocabulary development.

Inferring the motivations of others is a fundamental aspect of social interaction. However, making such inferences about infants can be challenging. This investigation examined adults' ability to infer the eliciting event of an infant's behavior and what information adults utilize to make such inferences. In Study 1, adult participants viewed recordings of 24-month-old infants responding to an actor's emotional display (joy, sadness, fear, anger, or disgust) toward a broken toy and were asked to infer which emotion the actor expressed using only the infant's behavioral responses. Importantly, videos were blurred and muted to ensure that the only information available regarding the actor's emotion was the infant's reaction. Overall, adults were poor judges of the elicitors of infants' behaviors with accuracy levels below 50%. However, adults' categorizations appeared systematic, suggesting that they may have used consistently miscategorized emotions. To explore this possibility, a second study was conducted in which a separate sample of adults viewed the original recordings and were asked to identify infants' goal-directed behaviors (i.e., security seeking, social avoidance, information seeking, prosocial behavior, exploration, relaxed play). Overall, adults perceived a variety of infant differentiated responses to discrete emotions. Furthermore, infants' goal-directed behaviors were significantly associated with adults' earlier "miscategorizations." Infants who responded with specific behaviors were consistently categorized as having responded to specific emotions, such as prosocial behavior in response to sadnesss. Taken together, these results suggest that when explicit emotion information is unavailable, adults may use heuristics of emotional responsiveness to guide their categorizations of emotion elicitors.
RESUMO
Face perception is susceptible to contextual influence and perceived physical similarities between emotion cues. However, studies often use structurally homogeneous facial expressions, making it difficult to explore how within-emotion variability in facial configuration affects emotion perception. This study examined the influence of context on the emotional perception of categorically identical, yet physically distinct, facial expressions of disgust. Participants categorized two perceptually distinct disgust facial expressions, "closed" (i.e., scrunched nose, closed mouth) and "open" (i.e., scrunched nose, open mouth, protruding tongue), that were embedded in contexts comprising emotion postures and scenes. Results demonstrated that the effect of nonfacial elements was significantly stronger for "open" disgust facial expressions than "closed" disgust facial expressions. These findings provide support that physical similarity within discrete categories of facial expressions is mutable and plays an important role in affective face perception.

This study explored the temporal contingencies between infant and adult vocalizations as a function of the type of infant vocalization, whether adult caregivers' vocalizations were infant-directed or other-directed, and the timescale of analysis. We analyzed excerpts taken from day-long home audio recordings that were collected from nineteen 12- to 13-month-old American infants and their caregivers using the LENA system. Three 5-minute sections having high child vocalization rates were identified within each recording and coded by trained researchers. Infant and adult vocalizations were sequenced and defined as contingent if they occurred within 1â¯s, 2â¯s, or 5â¯s of each other. When using 1â¯s or 2â¯s definitions of temporal adjacency, infant vocalizations generally predicted subsequent infant-directed adult vocalizations. A reflexive vocalization (i.e. a cry or a laugh) was the strongest predictor. Likewise, within 1-2â¯s timeframes, infant-directed adult speech generally predicted infant vocalizations with reflexive vocalizations being particularly predictive. Infant vocalizations predicted fewer subsequent other-directed adult vocalizations and were less likely following other-directed adult vocalizations when considering up to 5â¯s lags. This suggests an understudied communicative role for infants of non-infant-directed adult speech. These results demonstrate the importance of timescale in studying infant-adult interactions, support the communicative significance of reflexive infant vocalizations and other-directed adult speech in addition to more commonly studied vocalization types, and highlight the challenges of determining direction(s) of influence when using only two-event sequences.

Affective face perception is influenced by nonfacial contextual elements. However, investigations often conflate body posture and emotion scene, making it unclear whether posture or the combination of posture and scene produces perception-altering effects. This study examined adults' categorizations of disgust facial expressions superimposed onto isolated emotion postures or postures embedded in emotion scenes. Results indicated that emotional postures exerted a significant contextual effect on adults' emotion categorizations of disgust faces. Of note, postures in emotion scenes exerted a stronger contextual effect than isolated postures for sadness and fear contexts. These findings suggest that contextual elements exert varying degrees of influence on emotion perception and produce combinatorial effects. (PsycINFO Database Record

Emotional communication regulates the behaviors of social partners. Research on individuals' responding to others' emotions typically compares responses to a single negative emotion compared with responses to a neutral or positive emotion. Furthermore, coding of such responses routinely measure surface level features of the behavior (e.g., approach vs. avoidance) rather than its underlying function (e.g., the goal of the approach or avoidant behavior). This investigation examined infants' responding to others' emotional displays across 5 discrete emotions: joy, sadness, fear, anger, and disgust. Specifically, 16-, 19-, and 24-month-old infants observed an adult communicate a discrete emotion toward a stimulus during a naturalistic interaction. Infants' responses were coded to capture the function of their behaviors (e.g., exploration, prosocial behavior, and security seeking). The results revealed a number of instances indicating that infants use different functional behaviors in response to discrete emotions. Differences in behaviors across emotions were clearest in the 24-month-old infants, though younger infants also demonstrated some differential use of behaviors in response to discrete emotions. This is the first comprehensive study to identify differences in how infants respond with goal-directed behaviors to discrete emotions. Additionally, the inclusion of a function-based coding scheme and interpersonal paradigms may be informative for future emotion research with children and adults. Possible developmental accounts for the observed behaviors and the benefits of coding techniques emphasizing the function of social behavior over their form are discussed. (PsycINFO Database Record

Emotion can be communicated through multiple distinct modalities. However, an often-ignored channel of communication is posture. Recent research indicates that bodily posture plays an important role in the perception of emotion. However, research examining postural communication of emotion is limited by the variety of validated emotion poses and unknown cohesion of categorical and dimensional ratings. The present study addressed these limitations. Specifically, we examined individuals' (1) categorization of emotion postures depicting 5 discrete emotions (joy, sadness, fear, anger, and disgust), (2) categorization of different poses depicting the same discrete emotion, and (3) ratings of valence and arousal for each emotion pose. Findings revealed that participants successfully categorized each posture as the target emotion, including disgust. Moreover, participants accurately identified multiple distinct poses within each emotion category. In addition to the categorical responses, dimensional ratings of valence and arousal revealed interesting overlap and distinctions between and within emotion categories. These findings provide the first evidence of an identifiable posture for disgust and instantiate the principle of equifinality of emotional communication through the inclusion of distinct poses within emotion categories. Additionally, the dimensional ratings corroborated the categorical data and provide further granularity for future researchers to consider in examining how distinct emotion poses are perceived.
RESUMO
The onset of walking is a developmental transition that sets in motion a cascade of change across a range of domains, including social interactions and language learning. However, research on the unfolding of such change in the infant across this transition is limited. This investigation utilized a longitudinal design to examine the effect of walking acquisition on infant social development and parent perceptions of the infant to explore how changes in these factors relate with infant language development. Parents reported on infant social behaviors and their perception of the infant, as well as motor and language development, in 2-week intervals from 10.5 to 13 months of age. Mixed linear models revealed infant initiation of joint engagement (e.g., pointing, bringing objects to the parent) and following of the parent's joint engagement cues (e.g., point following, gaze following) increased as a function of infant walking experience, particularly between 2- and 4-weeks after the onset of walking, independent of age. Additionally, the parent's perception of the infant as an individual increased between 2- and 4-weeks after the infant began to walk. Finally, the unique relations of infant walking experience, following of social cues, and the parents' perception of the infant as an individual with infant language development were examined. Infant following of joint engagement behaviors and parent perception of the infant as an individual were related to receptive, but not productive, vocabulary size. Additionally, infant walking experience remained a significant predictor of infant receptive and productive language. These findings provide insight on important factors that change as the infant begins to walk. Future research utilizing more direct assessment of these factors is described, as well as general patterning of developmental change across the transition from crawling to walking.
