Joint Attention in Human and Chimpanzee Infants in Varied Socio-Ecological Contexts

Joint attention (JA) is an early manifestation of social cognition, commonly described as interactions in which an infant looks or gestures to an adult female to share attention about an object, within a positive emotional atmosphere. We label this description the JA phenotype. We argue that characterizing JA in this way reflects unexamined assumptions which are, in part, due to past developmental researchers' primary focus on western, middle-class infants and families. We describe a range of cultural variations in caregiving practices, socialization goals, and parenting ethnotheories as an essential initial step in viewing joint attention within inclusive and contextualized perspectives. We begin the process of conducting a decolonized study of JA by considering the core construct of joint attention (i.e., triadic connectedness) and adopting culturally inclusive definitions (labeled joint engagement [JE]). Our JE definitions allow for attention and engagement to be expressed in visual and tactile modalities (e.g., for infants experiencing distal or proximal caregiving), with various social partners (e.g., peers, older siblings, mothers), with a range of shared topics (e.g., representing diverse socialization goals, and socio-ecologies with and without toys), and with a range of emotional tone (e.g., for infants living in cultures valuing calmness and low arousal, and those valuing exuberance). Our definition of JE includes initiations from either partner (to include priorities for adult-led or child-led interactions). Our next foundational step is making an ecological commitment to naturalistic observations (Dahl, 2017, Child Dev Perspect, 11(2), 79-84): We measure JE while infants interact within their own physical and social ecologies. This commitment allows us to describe JE as it occurs in everyday contexts, without constraints imposed by researchers. Next, we sample multiple groups of infants drawn from diverse socio-ecological settings. Moreover, we include diverse samples of chimpanzee infants to compare with diverse samples of human infants, to investigate the extent to which JE is unique to humans, and to document diversity both within and between species. We sampled human infants living in three diverse settings. U.K. infants (n = 8) were from western, middle-class families living near universities in the south of England. Nso infants (n = 12) were from communities of subsistence farmers in Cameroon, Africa. Aka infants (n = 10) were from foraging communities in the tropical rain forests of Central African Republic, Africa. We coded behavioral details of JE from videotaped observations (taken between 2004 and 2010). JE occurred in the majority of coded intervals (Mdn = 68%), supporting a conclusion that JE is normative for human infants. The JA phenotype, in contrast, was infrequent, and significantly more common in the U.K. (Mdn = 10%) than the other groups (Mdn < 3%). We found significant within-species diversity in JE phenotypes (i.e., configurations of predominant forms of JE characteristics). We conclude that triadic connectedness is very common in human infants, but there is significant contextualization of behavioral forms of JE. We also studied chimpanzee infants living in diverse socio-ecologies. The PRI/Zoo chimpanzee infants (n = 7) were from captive, stable groups of mixed ages and sexes, and included 4 infants from the Chester Zoo, U.K. and 3 from the Primate Research Institute, Kyoto University, Japan. The Gombe chimpanzee infants (n = 12) were living in a dynamically changing, wild community in the Gombe National Park, Tanzania, Africa. Additionally, we include two Home chimpanzee infants who were reared from birth by a female scientist, in the combined U.S., middle-class contexts of home and university cognition laboratory. JE was coded from videotaped observations (taken between 1993 and 2006). JE occurred during the majority of coded intervals (Mdn = 64%), consistent with the position that JE is normative for chimpanzee infants. The JA phenotype, in contrast, was rare, but more commonly observed in the two Home chimpanzee infants (in 8% and 2% of intervals) than in other chimpanzee groups (Mdns = 0%). We found within-species diversity in the configurations comprising the JE phenotypes. We conclude that triadic connectedness is very common in chimpanzee infants, but behavioral forms of joint engagement are contextualized. We compared JE across species, and found no species-uniqueness in behavioral forms, JE characteristics, or JE phenotypes. Both human and chimpanzee infants develop contextualized social cognition. Within-species diversity is embraced when triadic connectedness is described with culturally inclusive definitions. In contrast, restricting definitions to the JA phenotype privileges a behavioral form most valued in western, middle-class socio-ecologies, irrespective of whether the interactions involve human or chimpanzee infants. Our study presents a model for how to decolonize an important topic in developmental psychology. Decolonization is accomplished by defining the phenomenon inclusively, embracing diversity in sampling, challenging claims of human-uniqueness, and having an ecological commitment to observe infant social cognition as it occurs within everyday socio-ecological contexts. It is essential that evolutionary and developmental theories of social cognition are re-built on more inclusive and decolonized empirical foundations.

Cultural Orientation, Parental Emotion Socialization, and Adolescents’ Socio-Emotional Functioning Across Three Asian Cultures: India, China, and Singapore

Limited research has examined parental emotion socialization across Asian cultural contexts. Guided by the theoretical frameworks of family change and self-construal, this study examined cultural orientation toward independence-interdependence, parental emotion socialization processes, and their relations with adolescents’ psychological adjustment across three Asian cultural contexts—rural families in South India, suburban families in China, and families in Singapore. Participants included 300 Indian adolescents ( Mage = 15.58 years; 57.3% male) and their parents, 310 Chinese adolescents ( Mage = 13.04 years; 46.3% female) and their parents, and 241 Singaporean adolescents ( Mage = 14.44 years; 48.3% female) and their parents. Both adolescents and parents completed self-report measures of cultural orientation and emotion socialization, and adolescents completed a measure of their psychological adjustment. We first established construct validation for two emotion socialization processes and found that the factor structure for parental reactions varied across Asian contexts and parent versus adolescent reports, while the factor structure for parental emotion expressivity varied only across informants. Second, we tested whether the two parental emotion socialization processes mediated the association between cultural orientation toward independence-interdependence and adolescent behavior problems, and found differential relations across the three Asian contexts. Our data supported the model of family change and showed that across the Asian societies, the variations in independence-interdependence orientation provide different models of parental emotion socialization with nuances in meaning and function, as revealed by the construct validation of parental reactions and emotional expressivity and their implications for adolescents’ socio-emotional functioning.

Are Parents Less Responsive to Young Children When They Are on Their Phones? A Systematic Naturalistic Observation Study

This study examined whether parents are less responsive to their young children (0-5) when they use a phone. We systematically observed 53 parent-child dyads in consultation bureau waiting rooms and playgrounds. Twenty-three parents used their phone at least once during the observation. Across the dyads, we observed parent and child behavior during a total of 1,038 ten-second intervals. Of these intervals, 641 contained a bid for attention from the child. Accounting for the nested nature of the data, we found that the odds of parents responding to their child's bid for attention were five times lower when using a phone than when not using one. Moreover, parents' responses were less timely, weaker, showed less affect, and were less likely to prioritize the child over other activities. While being fully absorbed in one's phone significantly decreased the odds of responding compared to when not using a phone, occasionally glancing at the phone did not, suggesting that parents may have developed a "mode" of phone use for managing dual attention over the phone and the child. In addition, while a higher intensity of phone use does seem to matter, it did not differ from intense engagement in other nonchild directed activities. The incidence of fully absorbed phone use, however, is greater. Finally, the results show that asking for consent for the observation beforehand leads to a decrease in the odds of phone use, suggesting a social desirability bias. Overall, the findings support concerns over the impact of parental phone use on child development.

How Usual Is “Play As You Usually Would”? A Comparison of Naturalistic Mother-Infant Interactions with Videorecorded Play Sessions in Three Cultural Communities

In developmental research, mothers are frequently asked to “play as you usually would.” In this study, maternal behavior towards their three-month-olds in three cultural communities (Nso, Cameroon; Gujarati, India; Athens, Greece) was compared between videorecorded “play” situations and naturalistic observations. If there is consistency, videorecorded “play” episodes can be used as a proxy for daily behavior. Body contact, body stimulation, face-to-face situations, and object stimulation were coded. While individual mothers showed consistent levels of body contact and face-to-face and object stimulation in both situations, there were also high correlations across the different types of behaviors. Only body contact and object stimulation correlate significantly across behavioral frames but not with each other across or within either observational frame. They can therefore be understood as behaviors with some discriminatory power. Mothers generally show a higher frequency of behaviors in the videorecorded play situations than during the everyday observations across all three communities. However, the samples differ in the extent to which three of the four behaviors are seen more in the videorecorded play sessions. A broader and general understanding of mothers’ ethnotheories and daily activities in each community is required in order to interpret videographed “play as you usually would” situations.

‘Why I Sent My Child Away’

Although long-distance parenting is often depicted as a response to crisis (e.g., economic) or other stressful life events, it is sometimes undertaken in various culturally normative situations. This current study explores the motivations of South Asian Indian immigrant parents for sending their young children to India to live temporarily with their grandparents. This qualitative study involves in-depth interviews with first generation immigrant parents about their experiences and motivations for sending their children to India. Analysis of the data revealed five themes, namely, (a) contextual and daily challenges in caring for their children in the United States, (b) parents’ concern around paid group childcare, (c) grandparents as ideal caregivers but unable to stay in the United States, (d) presence of other extended network of relationships and support in India and (e) parents wanting their children to maintain their language and customs. Findings suggest culturally grounded beliefs around optimal childrearing (e.g., grandparents as ideal caregivers, presence of extended network of support in India and maintaining Indian traditions and values) and parents’ contextual needs (e.g., parents’ busy schedule around job and education) when traditional caregiving context changes due to migration to a new country. Implications for researchers are discussed.

Socialization environments of Chinese and Euro-American middle-class babies: Parenting behaviors, verbal discourses and ethnotheories

Children's socialization environments reflect cultural models of parenting. In particular, Euro-American and Chinese families have been described as following different socialization scripts. The present study assesses parenting behaviors as well as parenting ethnotheories with respect to three-month-old babies in middle-class families in Los Angeles and Beijing. Euro-American parents' behaviors towards their children, as well as their parental ethnotheories are assumed to express the cultural model of autonomy; whereas Chinese parents' socialization strategies are assumed to be shaped by the cultural model of relatedness. The results reveal that Euro-American and Chinese mothers embody different cultural models in their verbal parenting behaviors and verbalized parenting strategies. However, the differences are not consistent and there are no differences with respect to non-verbal parenting behaviors. The results are discussed as illustrating the complexity of cultural models of parenting, where cultural messages are expressed differently in different domains.

Infant engagement and early vocabulary development: a naturalistic observation study of Mozambican infants from 1;1 to 2;1

This study analyzes how others engage rural and urban Mozambican infants during naturalistic observations, and how the proportion of time spent in different engagements relates to infants' language development over the second year of life. Using an extended version of Bakeman and Adamson's (1984) categorization of infant engagement, we investigated to what extent a detailed analysis of infant engagement can contribute to our understanding of vocabulary development in natural settings. In addition, we explored how the different infant engagements relate to vocabulary size, and how these differ between the two communities. Results show that rural infants spend significantly more time in forms of solitary engagement, whereas urban infants spend more time in forms of triadic joint engagement. In regard to correlations with reported productive vocabulary, we find that dyadic persons engagement (i.e. interactions not about concrete objects) has positive correlations with vocabulary measures in both rural and urban communities. In addition, we find that triadic coordinated joint attention has a positive relationship with vocabulary in the urban community, but a contrasting negative correlation with vocabulary in the rural community. These similarities and differences are explained, based upon the parenting beliefs and socialization practices of different prototypical learning environments. Overall, this study concludes that the extended categorization provides a valuable contribution to the analysis of infant engagement and their relation to language acquisition, especially for analyzing naturalistic observations as compared to semi-structured studies. Moreover, with respect to vocabulary development, Mozambican infants appear to benefit strongest from dyadic Persons engagement, while they do not necessarily benefit from joint attention, as tends to be the case for children from industrial, developed communities.

Infants' behavioral styles in joint attention situations and parents' socio-economic status

In this study the eco-cultural model of parenting (Keller, H. (2007). Cultures of infancy. Mahwah, NJ: Erlbaum) was applied to the study of joint attention behavior of children from families with different socio-economic status (SES). It was hypothesized that infants' early communication styles would differ with SES reflecting more independent or interdependent interactions with their caregivers. It was also hypothesized that infants would use the same types of behaviors whether they have declarative or imperative communication goals. The Early Social Communication Scales (ESCS, Mundy et al., 2003) was administered to 103 typically developing infants of 12 months (approximately half of them siblings of children with autism). A factor analysis, yielding four behavioral factors, namely pointing, eye contact, actions and following points, confirmed the hypothesis that infants use behaviors consistently across situations independent of their communicative intent. MANOVAs (comprising parental education and income) revealed that higher SES infants showed actions more frequently in the ESCS whereas lower SES infants followed experimenter's points more frequently. The results are discussed in the context of presumably differing socialization goals for infants and the divergent contribution of parental education and income that seem to have additive contribution to some factors (actions, following points) but divergent contributions to others (pointing, eye contact).

The Importance of Development for Comparative Primatology

It is a truism to say that primates develop, but it is also important to acknowledge that development occurs across many domains, including motor behavior, socioemotional behavior, communication, and cognition. In this review, we focus on those aspects of development that impact social cognition outcomes in infancy. Triadic engagements, such as those of joint attention, cooperation, and intentional communication, develop in the first year of life in chimpanzees and humans. Joint attention, for example, occurs when infants coordinate their attention to a social partner while also attending to an object or event. Hominoids are strongly influenced by experiences during early development, especially experiences that are foundational for these coordinated triadic engagements. Purported species differences in triadic engagements are highlighted in current evolutionary theories of primate social cognition, but conclusions about species differences are unfounded when development is ignored. Developmental experiences must be matched, controlled, or systematically varied in experimental designs that make cross-species comparisons. Considerations of development, across species and across rearing experiences, would contribute to more accurate evolutionary theories of primate social cognition.

Putting the "Joy" in joint attention: affective-gestural synchrony by parents who point for their babies

Despite a growing body of work examining the expression of infants' positive emotion in joint attention contexts, few studies have examined the moment-by-moment dynamics of emotional signaling by adults interacting with babies in these contexts. We invited 73 parents of infants (three fathers) to our laboratory, comprising parent-infant dyads with babies at 6 (n = 15), 9 (n = 15), 12 (n = 15), 15 (n = 14), and 18 (n = 14) months of age. Parents were asked to sit in a chair centered on the long axis of a room and to point to distant dolls (2.5 m) when the dolls were animated, while holding their children in their laps. We found that parents displayed the highest levels of smiling at the same time that they pointed, thus demonstrating affective/referential synchrony in their infant-directed communication. There were no discernable differences in this pattern among parents with children of different ages. Thus, parents spontaneously encapsulated episodes of joint attention with positive emotion.

Profiles of Maternal Care Observed in a Group of Brazilian Mothers: an Exploratory Study

The aim of this study is to characterize profiles of maternal care in a sample of Brazilian mothers, using a culturalbiological perspective. Participants were 315 women who had at least one child younger than six years-old. They were selected from six Brazilian states. In each state, two groups of mothers were studied, one from the capital and one from a small city. They were interviewed and answered scales on allocentrism, social support, adult attachment, and practices of childcare. Mothers' characteristics, the type of context (capital vs. small city), and reported childcare practices were used in a Tree analysis. A Correspondence analysis was performed using the four clusters obtained and mothers' answers regarding their youngest child. Univariate GLM analyses were performed to compare mothers in the four clusters in terms of their scores on the different scales. Four maternal profiles presenting distinctive patterns of association between mothers' characteristics and care practices displayed to the youngest child were identified. We conclude that maternal care is a multi-determined phenomenon and that the method employed in this study can give insights into how the combination of diverse social-biological factors can result in a set of childcare practices.

Developing patterns of parenting in two cultural communities

This paper is aimed at analyzing verbal and nonverbal strategies in terms of body contact, face-to-face contact, and discourse style during the first three months of life in two cultural communities that have been characterized as embodying different cultural models of parenting: German middle-class, and Nso farmer families. It can be demonstrated that the Nso mothers have significantly higher rates of body contact during the assessments of free-play interactions during the first 12 weeks than the German women. The German women on the other hand demonstrate the expected increase of face-to-face contact, whereas the Nso women demonstrate a significantly lower and stable pattern of face-to-face contact over the assessments. The German mothers use an agentic discourse style, whereas the Nso mothers use a relational discourse style. Moreover, body contact and a relational discourse style form one parenting strategy, whereas face-to-face contact and the agentic discourse style form another parenting strategy. The results demonstrate culture-specific parenting strategies that not only differ with respect to the amount of behaviors expressed, but also the developmental course of particular behaviors. It is also evident that socialization strategies are expressed in different behavioral channels. The role of sociodemographic variables is particularly discussed with respect to their impact for defining sociocultural environments.

Socialization Goals and Parental Directives in Infancy: The Theory and the Practice

This study investigates the relation between parents’ explicit valuing of socialization goals and their behavior in naturalistic interaction with their infants. Parents of 26 infants from two different urban cultures (Portsmouth, United Kingdom, and Hyderabad, India) participated in this study. Using a multimethod approach, parents were observed in naturalistic interactions with their infants from 9.5 to 12.5 months, were given a socialization goals questionnaire, and were interviewed about their expectations and practices in relation to obtaining compliance to directives when the infants were 12.5 months. Parents in Hyderabad ranked relational goals and, in particular, the goal for compliance, significantly higher than parents in Portsmouth, and significantly higher than autonomous goals, whereas parents in Portsmouth ranked autonomous and relational goals equally. The group difference in the ranking of compliance was reflected in higher frequencies of parental directives in Hyderabad, but not in repetitions of directives or in lower acceptance of noncompliance. There were some significant correlations between ranking for compliance and the frequency of directive episodes or the likelihood of repeating a directive, but no relations at all with the likelihood of accepting noncompliance. Birth order significantly affected parent behavior, with parents of firstborns showing lower percentages of accepting noncompliance. The discrepancy between the expressed value for compliance and actual behavior in relation to obtaining it was partly explained through different parental discourse in the interviews, with more parents in Portsmouth adopting a “training” approach to compliance, and more parents in Hyderabad approaching compliance as something that would “develop with age.” Local contextual factors such as birth order as well as beliefs in the natural development of compliance with age might influence what parents do about noncompliance, independent of what they say about it.

Continuity in Parenting Strategies: A Cross-Cultural Comparison

This prospective longitudinal study is aimed at contributing to the understanding of cultural diversity concerning maternal parenting behaviors and conversational styles on one hand and continuity in parenting strategies on the other hand. It could be demonstrated that German middle-class families from Berlin and Indian Hindu middle-class families from Delhi represent two different cultural environments embodying different parenting strategies. The Berlin mothers focus on the cultural model of independence, whereas the Delhi mothers focus on the cultural model of autonomous relatedness. These different orientations are expressed in nonverbal and conversational behaviors with 3-month-old babies as well as in the play styles with 19-month-old toddlers. It could also be demonstrated that the parenting styles form continuous socialization environments. Especially the conversation styles that mothers use while talking to their 3-month-old babies were good predictors for the play styles with their 19-month-old toddlers. The results are discussed with an emphasis on parenting strategies as continuous and consistent cultural projects.

Sociocultural Influences on German and Turkish Immigrant Mothers’ Long-Term Socialization Goals

The major aims of this study were (a) to investigate the differences and similarities in long-term socialization goals of German mothers and Turkish immigrant mothers living in Germany and (b) to examine socialization goals of Turkish immigrant mothers in relation to their acculturation attitudes. Participants were composed of 79 Turkish mothers who were either raised in Germany or migrated to Germany and 91 German mothers of preschoolers living in Germany. Turkish immigrant mothers were more likely to expect their children to have close relations with the family and to be well-mannered and they were less likely to value autonomy than were German mothers. Turkish mothers who were more integrated into German culture were found to value individualistic goals such as self-control more than Turkish mothers who were more separated from the German culture, yet both groups valued mutual support within the family very highly. The findings reveal that socialization goal patterns of Turkish immigrant mothers represent the pattern depicted in the psychological interdependence model proposed by Kagitcibasi (2007).

Distal and proximal parenting as alternative parenting strategies during infants’ early months of life: A cross-cultural study

Cultures differ with respect to parenting strategies already during infancy. Distal parenting, i.e., face-to-face context and object stimulation, is prevalent in urban educated middle-class families of Western cultures; proximal parenting, i.e., body contact and body stimulation, is prevalent in rural, low-educated farmer families. Parents from urban educated families in cultures with a more interdependent history use both strategies. Besides these cultural preferences, little is known about the relations between these styles as well as the behavioural systems constituting them. In this study therefore, the relations between the styles and the constituting behaviours were analysed in samples that differ with respect to their preferences of distal and proximal parenting. The hypothesized differences between the samples and the negative relationship between distal and proximal parenting, as well as between the respective behavioural systems can clearly be demonstrated. Furthermore, the impact of the sociodemographic variables with respect to the parenting strategies can be shown. Results were discussed as supporting two alternative parenting strategies that serve different socialization goals.
