Middle children are “better people” than their siblings

A study led by psychologists Michael Ashtona and Kibeom Lee from the Canadian universities of Brock and Calgary sheds light on a family debate that has intrigued for years: Does birth order really influence our personality? The answer, according to their findings published in Proceedings of the National Academy of Sciences (PNAS), It especially favors middle children. Specifically, the research analyzed data from more than 710,000 people who had filled out profiles on a personality website, the HEXACO Personality Inventory, a tool that evaluates 6 key dimensions: honesty-humility, emotionality, extraversion, agreeableness, conscientiousness and openness to the experience. Middle children: more honest and cooperative according to data The results showed that the middle children, those with older and younger siblings, They obtained the highest scores in honesty-humility and agreeableness, followed by younger siblings, older siblings and, finally, only children. On the practical scale, This means that they tend to avoid manipulation, show little interest in wealth and luxuries, and are more likely to forgive and cooperate with others. But there is more: The study found that the number of siblings also matters. The larger the family, the higher the scores on these positive traits. Researchers suggest a quite logical explanation: in large families, cooperation is not optional, it is necessary for daily coexistence. “When you have more siblings, you should cooperate more frequently instead of acting according to selfish preferences,” Ashtona and Lee explain in their study, according to Live Science, suggesting that this constant need for cooperation could shape personality in the long term. The researchers considered additional factors that could influence the results. For example, since religious families tend to be larger, they analyzed the religious factor, which explained approximately 25% of the observed differences. However, birth order and family size remained determining factors. Birth order research: contradictory results Despite the striking results, science invites us to be cautious. As pointed out Live Science, the field of birth order study is filled with contradictory conclusions and popular stereotypes ranging from the brilliant firstborn to the spoiled child to the mediating middle child. For example, an analysis published in 2015 in PNAS already warned of this complexity: after 2 decades of research, the results ranged between strong correlations and the total absence of patterns, with the aggravating factor that many studies were based on limited samples. The strongest evidence to date also does not support a clear influence of birth order. An investigation with 20,000 participants from three countries (United States, United Kingdom and Germany) found no significant correlations. For its part, the Talent Project, which followed 272,000 Americans, only detected a modest intellectual advantage in older siblings. The most recent related studies also maintain this skeptical line. In 2020, research on narcissism found no differences between only children and those with siblings. In this context of disparate results, Ashtona and Lee’s new analysis provides a fresh perspective with its large sample of more than 710,000 participants, although the researchers themselves acknowledge that more studies will be needed to confirm whether middle children really have these distinctive characteristics. .

Why what we understand as “normal” development in children could be wrong

Image source, Getty Images photo caption, Due to the immense variety of components that affect the growth of a human being, it is very difficult to define something as “normal.” Item information Author, Samuel Forbes and Prerna Aneja Author’s title, The Conversation* January 14, 2025 For parents, caregivers and teachers, it is often tempting to base our understanding of a child’s development on what we believe is “normal.” We often do it without thinking, when we describe a child as “doing well” in one subject and “falling behind” in another. Whenever we make this kind of comparison, we have some kind of mental reference point in our heads: for example, a toddler should be able to climb furniture at age 2. Increasingly, child development researchers argue that the same is true in their field, the study of how behaviors and skills such as language develop. Many of the studies that claim to investigate child development, whether implicitly or explicitly, claim that their findings are universal. There may be many reasons for this. Sometimes there is a temptation to exaggerate conclusions, sometimes it can be the way readers or the media interpret the findings. The result is that what has been found in a group of children is then taken as the standard, the criterion against which future research is compared. Academic biases Image source, Getty Images photo caption, Most of the existing academic research on child development comes from Western countries. Most research on child development comes from wealthier Western countries, particularly the United States, the United Kingdom, the Netherlands, Germany, and France. Chances are, if you’ve heard of childhood development milestones, they occurred in one of these countries. This is because it can be difficult to conduct basic research on child development in developing countries, as colleagues and reviewers will ask or demand comparisons with Western populations to put findings from these regions in context. Of course, without realizing it, these colleagues and reviewers have established Western children as the norm. Complex environments Image source, Getty Images photo caption, Most academic studies on child development have been carried out in developed countries, and do not take into account development in other cultures. But is it fair to make these comparisons? One of the complicated aspects of child development research is that it occurs in a cultural and social context from which it cannot be separated. But this context is often confusing. Differences in physical environment, parenting styles, location, climate, etc. interact to shape children’s growth. In addition to these differences, there are also individual variations. These can be, for example, curiosity, shyness and neurodiversity, which can frame the way a child shapes their own learning environment. Take the field of childhood motor development: the study of how children learn to move. Many parents in particular may be familiar with charts showing when they can expect their child to sit, crawl, stand and run. The existence of these graphs makes it seem quite universal, and a child’s motor development is often judged in this way. This makes sense. Early research was concerned with finding out what was normal, and it makes sense to try to support children who might be at risk of falling behind. The time and order investigated then gave rise to the norms and scales that we still use today. Image source, Getty Images photo caption, Studies have standardized the stages of development, without taking into account that the environment affects each individual differently. Is something like the timing of motor development universal? It’s easy to imagine it could be. When there are no physical or cognitive barriers, we all learn to sit and stand, so at first glance it seems fair to say that it could be. But it turns out that the context in which children develop plays a very important role even in something as seemingly universal as this. In countries and cultures where babies routinely receive firm massages from their caregivers, such as in Jamaica, motor development accelerates. It is clear that a norm developed in one culture may not translate well to another. Beyond the rules Image source, Getty Images photo caption, Many times, research has no way to incorporate key information such as the social and cultural context of the children it studies. Clearly, the problems highlighted above are not unique to motor development. In areas such as language development or social development, the cultural component is even more pressing. There is simply no way to understand these elements of child development without also understanding the context in which they take place. Each child develops within a context and, no matter how normal our own culture may seem to us, There is no objective, context-independent standard with which we can compare other children.. That is, we should accept the disorder. If we think of normal child development as something that just happens, researchers miss understanding the dynamics of development itself. But worse, educators and caregivers may not realize that development is something we can act on, and they miss the opportunity to create change. Image source, Getty Images photo caption, Each child develops uniquely, and it is through that understanding that better results are achieved. An important part of viewing child development as intertwined with culture is that it not only means collecting data from other cultures, but involving local communities and research perspectives. Understanding communities means listening to them, empowering them and giving them space to have a voice. Moving beyond a Western-centric understanding of child development will not only benefit researchers and lead to more accurate science, but will hopefully benefit everyone who works with children around the world. *This article was published on The Conversation and reproduced here under the creative commons license.

Why are children more affected by norovirus?

Norovirus, also known as “stomach flu,” is registering a significant rebound in the United States, with children under 5 years old as the most vulnerable population. This virus is responsible for up to one million pediatric emergency room visits each year, according to the Centers for Disease Control and Prevention (CDC). Its high contagiousness and the conditions in which it proliferates make it a recurring threat, especially in environments such as schools and daycares. Below, we break down how to recognize this disease, why it affects children the most, and what steps to take to prevent its spread. What is norovirus? norovirus is a highly contagious virus that causes acute gastroenteritis, an inflammation of the stomach and intestines. The most common symptoms include: * Vomiting* Diarrhea* Abdominal pain* Mild fever Although it is called the “stomach flu,” this condition is not related to the flu caused by the influenza virus. Most people recover in one to 3 days, but the virus can continue to spread through feces and vomit for several days after symptoms appear. Norovirus is particularly concerning because It can survive on contaminated surfaces for long periods of time and resist many common disinfectants. This makes it especially problematic in closed, crowded spaces. Many children get sick from norovirus at this time of year because it is easy to spread. (Photo: Shutterstock) Why does norovirus affect children more? Children under 5 years old are especially vulnerable to norovirus for several reasons: 1) Immature immune system: It is still developing, which makes them more susceptible to severe infections.2) Hygiene habits: Young children tend to touch contaminated surfaces and frequently put their hands in their mouths, increasing the risk of infection.3) Environments conducive to the virus: Spaces such as daycares and schools facilitate transmission due to close contact between minors. Lisa Cooper, a microbologist at the University of California, explains: “Children touch everything and put their hands in their mouths more frequently than adults, which increases the risk of infection.” According to the CDC, norovirus is responsible for 2,270,000 outpatient visits annually, the majority in young children. In this age group: * 1 in 160 will require hospitalization*1 in 110,000 dies due to complications such as severe dehydration One of the main risks of norovirus is dehydration, which can be particularly dangerous in children. Signs of dehydration include: * Extreme fatigue* Dry mouth and throat*Reduced urine production* Dizziness*Drowsiness or irritability According to the Mayo Clinic, “dehydrated children may cry with few or no tears and become unusually sleepy.” If you experience any of these symptoms, you should seek medical attention immediately. The impact of the current norovirus outbreak In December 2024, 22.28% of the 1,940 people tested for norovirus tested positive, reflecting a worrying increase in cases. The CDC anticipates the outbreak will continue through the first weeks of 2025. Every year, norovirus illnesses in the US. generate losses of approximately $2,000 million dollars due to healthcare costs and loss of work productivity. Measures to prevent the spread of norovirus Preventing norovirus is key to reducing the burden on health systems and protecting children. The main measures include: Correct hand washing: * Use soap and water. * Wash your hands for at least 20 seconds, especially after using the bathroom, changing a baby’s diaper, or before eating. * Avoid relying exclusively on hand sanitizers, as they are less effective against norovirus. Surface disinfection: * Regularly clean toys, tables, doorknobs and other frequently touched surfaces with disinfectant solutions effective against viruses. Avoid sharing utensils and food: * Teach children not to share glasses, bottles or cutlery. * Keep sick children at home: * Do not send children to school if they have norovirus symptoms. This principle not only protects other children, but also teachers and school staff, who may also be affected. Libby Richards, a nursing professor at Purdue University, points out: “When sick children attend school, they not only infect their classmates, but also affect the quality of education due to faculty attrition.” With these measures, it is possible to protect children and minimize the impact of this highly contagious disease.
