When babies identify meaningful cultural differences

AdobeStock_83877423.jpeg
Note: This piece first appeared in the New York Times on August 19, 2016 as “Babies Watching People Eat”.

You may not be surprised to learn that food preference is a social matter. What we choose to eat depends on more than just what tastes good or is healthful. People in different cultures eat different things, and within a culture, what you eat can signal something about who you are.

More surprising is that the sociality of food selection, it turns out, runs deep in human nature. In research published this month in the Proceedings of the National Academy of Sciences, my colleagues and I showed that even 1-year-old babies understand that people’s food preferences depend on their social or cultural group.

Interestingly, we found that babies’ thinking about food preferences isn’t really about food per se. It’s more about the people eating foods, and the relationship between food choice and social groups.

While it’s hard to know what babies think before they can talk, developmental psychologists have long capitalized on the fact that babies’ visual gaze is guided by their interest. Babies tend to look longer at something that is novel or surprising. Do something bizarre the next time you meet a baby, and you’ll notice her looking intently.

Using this method, the psychologists Zoe Liberman, Amanda Woodward, Kathleen Sullivan and I conducted a series of studies. Led by Professor Liberman, we brought more than 200 1-year-olds (and their parents) into a developmental psychology lab, and showed them videos of people visibly expressing like or dislike of foods.

For instance, one group of babies saw a video of a person who ate a food and expressed that she loved it. Next they saw a video of a second person who tried the same food and also loved it. This second event was not terribly surprising to the babies: The two people agreed, after all. Accordingly, the babies did not look for very long at this second video; it was what they expected.

But when the babies saw the second person do something less expected — when this second person instead hated this same food that the first person loved — the babies looked much longer.

In this way, we were able to gauge infants’ patterns of generalization from one person to another. If babies see someone like a food, do they think that other people will like that food, too? And if so, do they think that all people will like the same foods, or just some people?

 

We found some surprising patterns. If the two people featured acted as if they were friends, or if they spoke the same language, babies expected that the people would prefer the same foods. But if the two people acted as if they were enemies, or if they spoke two different languages, babies expected that they would prefer two different foods.

It was as if cultural lines were being drawn right in the laboratory. And in the babies’ minds there seemed to be something special about the link between culture and food: When the babies saw people liking and disliking inedible objects, we didn’t observe the same patterns of results.

One thing you may be wondering — and we were, too — is whether this is all about the foods people like. Whether you like grits or kale may depend on cultural identity. But there are some things that are disgusting to all humans, regardless of culture. Do babies intuitively know this?

Indeed, they seem to. When the babies in our studies saw a person act disgusted from eating a food, they expected that a second person would also be disgusted by the same food — regardless of whether or not the two people were in the same social group.

We also discovered something interesting about what babies identify as meaningful cultural differences. Babies from monolingual English-speaking homes saw language as a marker of different cultures; as noted above, if two people spoke two different languages, babies expected that they would prefer two different foods.

In contrast, babies from bilingual homes assumed that even two people who spoke different languages would like to eat the same things. Thus babies have the potential to learn different things about the foods and people around them, depending on their social environments.

Parents of young children may want to take note of our findings. Infants are not just learning to eat the foods they are given; they are also learning by watching adults eat, and figuring out who eats what foods with whom. By introducing babies to social contexts in which adults make healthful food choices, parents may help children learn the cultural norms of healthful eating themselves.

How to raise kids well in the age of Trump

This post is an excerpt from “A Cornell psychologist explains how to raise kids well in the age of Trump” by our scholar Katherine Kinzler, originally published on Quartz. Click here to read the full piece.

children diversity

Like many, I hope to seek goodness amidst chaos. Regardless of who leads our nation, what can we do—individually and collectively—to inspire virtue in the next generation of children?

Encourage children to think independently. Psychology researchers used to reduce young children’s morality to their ability to follow authority. Fortunately, there is now good evidence that children can engage in their own moral reasoning. They can understand that just because an authority figure says that a negative action is permissible, it may nonetheless be morally wrong. Now is the time for us to encourage children to discover and evaluate evidence for themselves. We can remind them that just because a person is in power, their ideas are not always right.

Discuss the value of a democratic system. Legal scholar Tom Tyler and developmental psychologists Alex Shaw and Kristina Olson have shown that young and old people alike care about a fair decision-making process. People like it when they get their way, sure. But they also value a fair system.

Many Hillary Clinton supporters feel disappointed that Clinton won the popular vote but lost the election because of the electoral college. But while there may be good reasons to consider amending our system for the future, the fact is that Trump won under the system we have in place now. Children are smart enough to understand this. They can respect the process of a fair election, and they can also brainstorm how they might improve the procedural system used in the future.

Watch our own language. The psychologist Marjorie Rhodes has shown how quickly language can inadvertently transmit bias. When we talk about whole groups of people as being a certain way, it is very easy for children to learn biased feelings toward that group—and to think that members of that group are all the same. We should try our best to refer to people as individuals, not as members of racial, ethnic, or religious groups. It is also important to combat cultural notions that “boys play with trucks” or “girls like pink.” The more children hear about boys and girls as being two distinctly different kinds of groups, the more easily they pick up gender stereotypes.

Lead with actions, as well as with words. Children pick up on the nonverbal cues that we send them. This is true about learning racial prejudice and about learning adults’ views of who is high and low status. We can engage in simple acts of kindness and humanity, displayed toward people of all different groups. Invite friends who are different from you to your home. Smile at people who are different from you and sit next to them at the playground. Children are watching.

Expose children to diversity. In my own research, my colleagues and I have found that being exposed to multiple languages increases children’s abilities to take the perspective of others. Likewise, studies of children in racially heterogeneous schools suggest they are more egalitarian than children in racially homogeneous schools. Often, it is difficult to disentangle the effects of parents’ interest in diversity from the impact of the exposure itself. So cover your bases. Be the kind of parent who values diversity, and let your children enjoy the potential benefits of intergroup exposure.

Remind children that most people aren’t all good or all bad. Social psychologists Adam Waytz, Liane Young, and Jeremy Ginges have shown that different groups—including American Democrats versus Republicans and Israelis versus Palestinians—think their own groups’ aggressions are motivated by love for one another, whereas the other group’s aggressions are motivated by hate. In other words, an Israeli is likely to write off a Israeli’s hostility toward a Palestinian as being motivated by love of Israelis, whereas the same Israeli would think that a Palestinian’s hostility is owed to hatred.

It is easy to lapse into this kind of polarized thinking, which misattributes people’s motivations. Adults and children alike can be reminded that often what we perceive as negative or hurtful acts do not stem from equivalently negative or hurtful intentions. It is never a bad idea to consider how you or a loved one might feel if the tables were turned.

If you’re a woman, consider getting into politics—and encourage girls to do the same. In a university setting, we often worry about the dearth of women in math and science fields. But in multiple levels of American politics, there is also an underrepresentation of women. Building a pipeline for female governance will be difficult without sufficient role models for girls to follow. Women who want to help can consider getting involved in politics themselves and by making themselves visible and accessible to a generation of girls who will be inspired to join them.

Together, people of all backgrounds can encourage their children to help build a nation that prides itself on embracing difference.

Food Preferences, Temperance, and Virtue

The concept of habit plays a central role in Thomas Aquinas’ moral theory, and in his analytic psychology more generally. He identifies habits as one of the fundamental principles of human action, together with the capacities of intellect, passions, and will – appropriately so, because habits are nothing other than stable dispositions of these capacities, which enable them to operate in coherent, appropriate ways. Habits are subject to moral evaluation, just as actions are, and the habits of the passions and the will are always either virtues or vices, just as human actions are always morally good or evil. Even more fundamentally, habits of some kind are necessary to the functioning of both the appetites and the intellect. Without some kind of internal development and formation, the appetites and the rational powers of the human creature cannot function at all, or can only operate in rudimentary and ineffective ways. By implication, human action as we know it, whether from our experience as agents or by observation of others, is almost always shaped by habits of some kind, formed out of natural (or supernatural) principles of operation through processes of training and development. Human existence and action is ultimately grounded in natural principles, but the innate principles of human action do not enter directly into our ordinary experiences – rather, we act and interact with one another through the structures set up by the stable dispositions of our virtues, vices, and other habits.
These are claims about the origins and structuring principles of human action, and as such, they invite comparison with other kinds of claims about human psychology, including those set forth by contemporary experimental psychology. A comparison of this kind might seem to be ruled out by the radical differences in assumptions and methodology that divide Aquinas from contemporary scientists of any kind. Yet when we compare what Aquinas says about the habits, we find unexpected resonances with recent work on the formation of stable dispositions, especially those relating to such fundamental matters as food preferences. We need to be careful not to overstate the extent and significance of these resonances. However, it would seem that at the very least, Aquinas and contemporary psychologists share points of reference that enable us to compare them in fruitful ways. To put it crudely, we can assume that they are talking about the same things, more or less, namely, human activities and experiences, together with whatever principles or structures account for these.
I want to defend and develop this way of approaching Aquinas’ psychology by comparing what he says about the formation and necessity of habit with recent work on the formation of food preferences in infants. This research lends support to Aquinas’ view that even the most fundamental human capacities for desire and aversion need some kind of rational formation and structuring in order to function properly. Indeed, Aquinas’ analytical psychology and contemporary experimental psychology seem to converge, and for a Thomist, this convergence suggests that research in this area might tend to confirm—or at least shed light on—Aquinas’ account of a virtue such as temperance, as it pertains to the pleasures of food and drink. When we turn back to relevant studies, however, it would seem that they challenge Aquinas’ account of temperance, insofar as he defines this virtue by reference to the individual’s bodily needs. On further reflection, contemporary work on food preferences is not inconsistent with Aquinas’ account of temperance, but it does suggest that a Thomistic account of the virtue of temperance needs to be expanded and developed in certain ways, if we are to do full justice to the complexities of developmental formation.

Habits are commonly associated with stereotyped, repetitive behaviors that often fall outside the range of one’s conscious awareness and may even be experienced as somehow contrary to one’s desires. A habit in the Thomistic sense more nearly resembles a skill, such as touch typing, than a habit like pulling one’s beard – indeed, the skill of touch typing is a habit in Aquinas’ sense, whereas beard-pulling is not. Habits understood in this way are clearly more interesting and important than the kind of habits that we only notice when we want to break them. But we have not yet taken full account of just how important habits are, on Aquinas’ view. He claims that habits of some kind are necessary for the proper functioning of the rational creature. Human capacities for perception, understanding, and desire are naturally indeterminate, and stand in need of some level of development in order to function at all.
Contemporary developmental psychology offers at least one example of a kind of system that would appear at first glance to function in much the same way as do the habits, as Aquinas understands them: “[E]ach of a multitude of core knowledge systems emerges early in development, serves to identify the entities in its domain by analysing their distinctive characteristics, and supports the acquisition of further knowledge about those entities by focusing on the critical features that distinguish different members of the domain (Shutts et al).” A system of core knowledge would thus seem to provide the same kinds of rational structures, and thus to facilitate appropriate functioning, in the same way that habits do. Systems of core knowledge would not be equivalent to habits as Aquinas understands them, but on the contrary, they would provide evidence that habits in this sense would be superfluous.

We can tentatively identify at least one such system that appears to be comprised of highly general concepts, which can only function properly after some level of formation, namely, the system of core knowledge with respect to food. For more than thirty years, psychologists have been studying the emergence and development of the infant’s ability to distinguish between edible and inedible objects, and between appropriate and healthy, or inappropriate, spoiled, or otherwise unsuitable food. In contrast to adults, older children, and at least some kinds of non-human primates, human infants are remarkably indiscriminate with respect to what they will ingest; one study summarizes that “items regarded by adults as dangerous, disgusting, or inappropriate, and combinations of individually liked foods that are unacceptable to adults were readily accepted by many of the younger children in our sample…. [However,] within the 16 month to five year age range studied, there is a clear developmental trend towards rejection of items that adults consider disgusting or dangerous.” (Rozin)

Indeed, recent research indicates that the food preferences of young children are not only formed through social interactions, but strongly tied to perceptions of, and feelings about, group identity. This research supports what experience would seem to confirm, that our habituated desires for specific foods may reflect our sense of social identity and a socially mediated sense of what is desirable, seemly, or appropriate for those of our kind. If this is so, then it would appear that at an early stage, the developing child begins to develop normatively laden food preferences, reflecting basic judgments about what one ought to eat.

This way of construing the development of food preferences is highly suggestive from the standpoint of a Thomist virtue ethicist. The virtue of temperance, for example, is a habitual disposition towards desires and aversions that reflect normative judgments of some kind. Any suggestion that early childhood food preferences develop in accordance with normative judgments will be grist to the mill for a contemporary Thomist. At the same time, we need to be careful not to move too quickly between contemporary psychology and Aquinas’ account of temperance. It is not immediately evident that the normative ideal informing temperance is the same as the normative standards informing the food preferences of young children. This does not mean that recent research disconfirms Aquinas’ analysis of temperance, but it does point to a more interesting way of thinking about the relation between these two very different ways of thinking about our most basic desires.
