    What makes us human? How minds develop through social interactions

    Just how social we are as a species is made even more evident by the COVID-19 lockdowns that have restricted our everyday social interactions and affected our physical and mental health. Social engagement influences us at an even more fundamental level because it is crucial to the formation of human thinking and minds. We address this issue in What Makes Us Human? How Minds Develop Through Social Interactions. In the words of a 9-year-old, the question is, “How do you go from a bunch of cells to something that thinks?” How are we as humans able to explore such questions about our own origins and the workings of our minds? Humans are intrigued by the possibility of intelligent life elsewhere in the universe, but a puzzle unfolding right before our eyes is how intelligence develops in our homes as babies start to communicate and then understand the world in ways that adults simply take for granted. In our book, we develop and justify the idea that the essential aspects of being human arise through our relations with other people. To understand these processes and the way human intellect develops, it is essential to look closely at the nature of communication in infancy and childhood, with which much of our thinking is intricately entwined. To explore the complexities of human language, we begin by describing the rich social and emotional niches in which human babies develop and the forms of interaction on which communication is based emerge. We develop and justify the idea that the essential aspects of being human arise through our relations with other people. Have you ever considered why human infants are born so helpless that they must be cared for over many years, yet they develop such powerful ways of thinking? Our answer to this question follows a historical tradition that suggests that this helplessness is an important factor in the development of human thinking. This is because the need for constant care in the early years necessarily produces a social context in which complex human skills develop. Although the infant is unable to fend for herself, she is born with a host of evolved biological characteristics that draw her into engagement with others. For example, typically developing babies are interested in looking at human eyes, which are particularly striking compared to the eyes of other primates because the dark center is surrounded by contrasting white sclera. Such attentiveness to eyes may be interpreted as indicating babies’ apparent interest in other people, and this interest is typically reciprocated by parents, who love to engage with their infants. This bidirectional process of attentiveness promotes the infant’s development. Initially, this consists of staring into the eyes of a caregiver, or cuddling into the caregiver for comfort, but these early and simple skills soon develop into more complex abilities like smiling or cooing. These new forms of interaction elicit even more positive experiences because they are so rewarding for parents. This repeated daily social interaction between infants and their parents becomes increasingly coordinated, which reflects early forms of communication. For instance, when a baby reaches her arms toward her parent, the meaning of this action — a desire to be held — is clear to the parent, who typically picks up the baby. Through experiencing this response to her reaching, the baby learns to anticipate this outcome of her reaching action. That is, she comes to grasp the meaning that her action has for others and then she gradually learns to communicate this desire intentionally. This is a crucial change in ways of interacting, not seen to such an extent in other species that lack an extended period of helplessness: The baby becomes aware of the meaning in the interaction and can then anticipate the response and communicate intentionally. Later, she can learn to add words such as up or uppy to these sorts of shared social routines. Other acts, such as mutually sharing a toy with a caregiver or gesturing in a specific way, develop in a similar fashion as their meaning emerges within shared patterns of interaction. Beginning at about 10 to 12 months, babies typically start to point, but not in a sophisticated way. It takes a lot of experience to realize that successful pointing involves the pointer gesturing to the object and checking that the receiver is following the line of the point. It also requires the receiver to identify what is being pointed to and why their attention is being drawn to it. The hard-won reading of these sorts of gestures reveals the origins and nature of children’s understanding of other people. It shows how a grasp of simple experiences like reaching to be picked up facilitates further interaction in which children develop yet more complex communicative and social skills. These are concrete examples of how increasingly sophisticated human thinking and minds emerge as communication develops in everyday interaction, a fact that makes their significance easy to overlook. They are instances of the sort of mundane interactions on which human ways of being and thinking are based. The use of words is an extension of earlier communication with gestures. Language gradually becomes part of the way thinking can take place. Initially, the baby’s words refer to objects and actions in the here and now, but gradually they can be applied to experiences not directly perceptible – for example, toddlers can relate what happened at preschool or make up a story about an imaginary character. More sophisticated forms of social understanding emerge when children gradually master the language skills needed to talk about human activity in psychological terms. Most toddlers articulate what they want with words by age two, and soon afterwards use words like think and know to show that they are aware that they and the people around them are influenced by their own thoughts and motivations. By acquiring the ability to talk about the psychological world, children can begin to reflect on themselves and others in these ways. From the perspective we have developed here, morality emerges at the level of interaction as children learn to coordinate their daily activities with others in relationships of mutual affection and respect. These interactions based on equality are well suited for reaching mutual understanding because they require children to listen to others and explain themselves. This allows them to coordinate conflicts and develop a practical morality in their interaction with equals. A further step is to begin to articulate what was first implicit in their activity, which then makes reflection possible. In this way, children become able to articulate and reflect on their initially practical ways of interacting with others. Moral notions such as fairness and justice do not have their source in biology alone, nor are they pre-existing and passed on from a previous generation to be imposed on children. Instead, they arise through particular forms of cooperative interaction among equals based on mutual affection and respect. To understand the way human intellect develops it is essential to look closely at the nature of communication in infancy and childhood, with which much of our thinking is intricately entwined. Of course, explaining the origins of human thinking is controversial and not everyone will agree with our account. In our book, we compare our developmental account, which is grounded in the processes of social interaction, with two competing explanations for human thinking: that it is either simply determined by biology or that the computer makes a good metaphor for the human mind. First, we show that although biological factors are crucial in structuring the developmental system in which human skills emerge, the claim that thinking is determined by genes is incompatible with work in biology over the last 50 years. Research in genetics and developmental neurobiology highlights that we must consider the complex developmental system in which multiple levels of biology and environment interact with each other to drive the individual’s development. Key aspects of human thinking, although based on neural activity, emerge only at the level of the person interacting with others. Second, the claim that thinking can be likened to computation is based on a flawed assumption that meaning is fixed, as it is in a computer. Instead, as we illustrate, human communication is rooted in shared ways of interacting. This is also why current approaches to artificial intelligence that attempt to model human intelligence are based on the wrong foundation. Revealing the flaws in these two general approaches to human psychological development supports our argument that human communication and thinking emerges within interaction with others in a developmental system in which biological and social levels are thoroughly interwoven. We trace this development by beginning as gestures emerge in early interaction, leading to language and then to human forms of thinking. Header photo: Gigin Krishnan. Creative Commons.  More

    Children’s play in the COVID-19 pandemic

    Why do children need play now more than ever, and how can parents engage their children in high-quality play activities?
    “While I am preparing dinner, I see my oldest daughter (Sefae, age 7) playing outside. She is wearing one of our face masks and pretends to be a shop owner. All the supplies are neatly placed on a picnic table. One of her friends, also wearing a face mask, joins her and helps with pricing the items. After a while, some other kids from the neighborhood join them in the role of guard or customer.”
    “During dinner, I ask my daughter what they were playing. Sefae: ‘We opened a new shop and we had a lot of customers. Yasmine and Max were the guards and made sure nobody was stealing and that all the customers kept some distance from one another. We had to wear face masks because of corona.’”

    “Join your child and play along!”

    So speaks one of the authors of this piece. For young children, play provides an important context to explore the world, gain new knowledge, and develop language and social abilities. In the example above, we can see how Sefae and her friends are playing as if they work in a shop. In this imitation of a real-world activity, they learn about different roles and the discourse associated with these roles. They also negotiate rules, communicate with one another, and practice their social skills. We also see how they incorporate elements of their new reality — wearing face masks and practicing physical distancing — as a way to deal with or understand the changes in their environment.
    In the current COVID-19 pandemic, play has become more important than ever before. First, children are increasingly confronted with insecurity and changes. For example, they see people wearing face masks, find that new rules apply in school, and might notice how their parents or caregivers struggle with issues like health or financial instability. Play can be an important activity for children to cope with, process, and understand these changes. Second, as schools close or teachers have to quarantine, there is less time for children to engage in high-quality play activities. Such play activities can provide a unique learning context for the development of different cognitive domains.
    What are high-quality play activities? One important aspect that contributes to high-quality play is the role of adults. Research shows that guided play activities in which adults play along, ask questions, follow-up on what their children say, and broaden the activity support children’s learning. This is not easy! Most parents are great as parents, but they might not be fully equipped to design meaningful play activities, connect these activities to learning, and participate in a responsive and sensitive manner.

    “For young children, play provides an important context to explore the world, gain new knowledge, and develop their language and social abilities.”

    How can we make sure children keep playing during this pandemic? Here are four evidence-informed suggestions:
    First, during role play, children reenact the world around them (as shown in the example of Sefae and her friends). The social roles of customer, shop owner, or guard were played out using different props. In research on play, props are one of the most critical elements of children’s play (Leong & Bodrova, 2012). But before you rush online to buy new toys and props, bear in mind that straightforward, realistic toys are not necessary for successful role play. Most realistic toys are suitable for only one type of play scenario, thus resulting in limited use. In contrast, using common household objects — combined with a young child’s imagination — opens a world of endless possibilities. The imagination of a child can transform a piece of cardboard, a broom, or a wooden stick into meaningful props. Parents should encourage children to use materials that offer open-ended opportunities for transformation and provide them with a variety of props.
    Second, besides role play, parents have numerous opportunities to engage their children in object-oriented play. Playing with objects is an accessible activity that benefits young children’s cognitive development. For example, research has shown that playing with blocks provides a unique context in which children learn spatial language (words like in, out, on top, and behind). To guide object-oriented play, parents can provide objects and materials (e.g., blocks, cars), play along, talk, give suggestions, and ask questions (e.g., “How can we make our building higher?” “Can you pass me that big block?” “What do we need to build a (…)?”). Furthermore, schools can support parents in increasing the quality of play activities at home, for example, by providing ideas for play scenarios. Some pictures that depict different stages of a building under construction can help parents guide their children and increase the level of quality of play activities.
    Third, parents are allowed to participate in their child’s play. In fact, young children often need some guidance from adults. Before starting a play activity, parents can discuss what cultural activity the children want to imitate or what materials they would like to play with. You can ask which roles are involved in this activity, who will play what role, and what kind of behaviors are suitable for these roles, as well as which props or materials are needed. Parents can also discuss different scenarios, for example, “What will happen?” or “What would you like to build?” During a play activity, parents can broaden or deepen the activity by introducing new props, materials, roles, language, and behaviors, thereby enriching children’s experience. However, before parents join children in play, they should observe what the children are doing, what is happening, and what the conversation is about. Then, they can decide how to raise the play activity to a higher level without disturbing the child’s play. In other words, look carefully, but don’t just stand on the side and watch: Join your child and play along! Occasionally, parents can take a picture during a play activity and send it to their child’s teacher. Teachers can use these pictures as a starting point for classroom talk or to connect play at home with play in school.
    Finally, as in the example of Sefae, during mealtimes, parents can have interesting and stimulating conversations with their children about their play activities. For example, they can ask: “What were you playing?” or say: “I noticed that you were talking about (…); is that correct?” or invite: “During your role play you were (…); can you say more about that?” These small conversations can give parents more insight in their children’s world, thoughts, knowledge, and concerns, and can support children’s language development (Snow & Beals, 2006). And children’s answers might provide parents with interesting leads for planning the next day’s play activity.

    Positive parent-child reminiscing about past experience helps early childhood emotional development, but maltreated children experience less of it

    Is maltreatment by parents associated with less quantity and quality of parent-child reminiscing on the child’ past, and, if so, is this a mechanism by which maltreatment leads to poorer early childhood emotional development? Researchers who asked this question in a recent study found a pathway between maltreatment and emotional development. Specifically: Maltreatment predicts less […] More
