“Fishy Business: Study Reveals Link Between Seafood Intake and Kindness in Children”

Children who consumed the least amounts of seafood at 7-years-old were likely to be less ‘prosocial’ at ages 7 and 9 years than those who regularly consumed seafood, according to a new study. ‘Prosocial’ behavior includes friendly interactions, altruism, and sharing.

A new study from the University of Bristol has shed light on the importance of seafood intake for children’s social development. Researchers analyzed data from over 5,900 participants in the Children of the 90s study and found that kids who consumed the least amounts of seafood at age 7 were likely to be less “prosocial” at ages 7 and 9.

Prosocial behavior includes friendly interactions, altruism, and sharing – essential traits for building strong relationships and a well-functioning society. The researchers adjusted their findings for social and demographic factors, ensuring that the results are reliable.

While previous studies have focused on the impact of seafood consumption during pregnancy on child development, this research highlights the significance of fish intake in children themselves. According to Dr. Caroline Taylor, Associate Professor in Nutrition at the University of Bristol, “Our evidence to link fish consumption in children with the best behavioral development is clear.”

The National Health Service (NHS) recommends that children consume at least two portions of fish per week, with one being an oily fish like salmon or mackerel. However, nearly all the children in this study were not meeting these guidelines.

Dr. Taylor emphasizes that while some experts have warned about the potential risks of overconsumption of fish due to pollutants like mercury, “encouraging fish consumption is likely to have a positive effect on child development.” She recommends parents provide at least two portions of fish per week for their children.

This study is part of the Children of the 90s research, which has been ongoing since the early 1990s. The latest funding will allow this pioneering longitudinal study to continue its work, focusing on the third generation of participants.

The findings of this study have significant implications for parents and policymakers, highlighting the importance of good nutrition in childhood development and social behavior. By providing children with a balanced diet that includes seafood, we can give them the best start in life – one that is likely to lead to better social skills, kindness, and empathy towards others.

Unlocking Mental Well-being: Everyday Behaviors That Boost Happiness

Research from Curtin University has revealed that everyday actions like chatting with friends, spending time in nature, and engaging in mentally stimulating activities can significantly improve mental well-being. The study surveyed over 600 Western Australian adults and found that those who practiced these behaviors on a daily basis scored higher on a standard mental well-being scale than those who did so less frequently.

The research highlighted the importance of social connections, physical activity, spirituality, and helping others in maintaining good mental health. Participants who chatted with friends every day scored 10 points higher on average, while spending time in nature daily was associated with a five-point increase. Other behaviors linked to improved mental well-being included frequent catch-ups with friends, physical activity, practicing spirituality, and engaging in mentally stimulating activities like crosswords or learning a new language.

Lead author Professor Christina Pollard emphasized that these findings offer clear evidence of the power of simple, low-cost actions in promoting good mental health and well-being. “These aren’t expensive programs or clinical interventions,” she said. “They’re behaviors that are already part of many people’s lives and can be easily encouraged through public health messaging.”

The study also evaluated 15 behaviors promoted by the Act Belong Commit campaign and found that mental well-being increased consistently with the frequency of participation in these behaviors. Awareness of the campaign was high, with 86 per cent of participants recognizing it, and nearly all agreed that mental health should be prioritized alongside physical health.

Despite being conducted during the COVID-19 pandemic, when social interactions were limited, 93 per cent of respondents reported no psychological distress, and average mental well-being scores were comparable to international pre-pandemic norms. Professor Pollard noted that this research provides a strong case for long-term investment in population-wide mental health promotion campaigns that go beyond awareness and empower people to take meaningful action.

“This research confirms that when people are supported and encouraged to engage in mentally healthy behaviors, the benefits can be felt across the community,” she said. “It’s about prevention, not just treatment – helping people stay mentally well before they reach crisis point.”

The Importance of Handwriting in Children’s Reading and Writing Development

Researchers explored how manual and keyboard practice influenced children’s abilities in their reading and writing learning process. 5-year-olds were taught an artificial alphabet using different techniques, and the conclusion was that children who are trained with pencil and paper assimilate new letters and words better.

The article discusses the findings of a study conducted at the University of the Basque Country (UPV/EHU) that compared the effects of manual and keyboard training on children’s reading and writing skills. The researchers concluded that children who used their hands to practice handwriting obtained better results than those who typed on keyboards.

The study involved 50 children aged 5-6 years, who were taught new letters and words using either manual or keyboard-based methods. The researchers found that the group that practiced handwriting had a greater ability to identify, write, and pronounce both the letters and the pseudowords compared to the group that used keyboards.

One of the key findings was that the graphomotor function – the ability to make precise hand movements while writing – played an essential role in memorizing letter and word structures. The researchers also discovered that variability in handwriting practice had a positive effect on learning, with children who practiced freely obtaining better results than those who followed guides or used standard fonts.

The study’s lead researcher, Joana Acha, emphasized the importance of prioritizing manual practice in learning processes, stating that “children learn best from hand movements and so technological devices should only be used in a complementary way.” This suggests that while digital tools can be useful for certain aspects of learning, traditional handwriting practices are essential for developing reading and writing skills.

Overall, the study’s findings have significant implications for educators and parents who want to support children’s learning and development. By prioritizing manual practice and providing opportunities for children to engage in free-writing activities, we can help them develop the skills they need to succeed in school and beyond.

Little Minds Big Learning: 15-Month-Old Infants Learn New Words for Objects from Conversations Alone

A new study by developmental scientists offers the first evidence that infants as young as 15 months can identify an object they have learned about from listening to language — even if the object remains hidden.

Researchers at Northwestern University and Harvard University have made a groundbreaking discovery about the way infants learn new words for objects. A study led by Sandra Waxman, senior author and Louis W. Menk Professor of Psychology, found that 15-month-old babies can identify an object they’ve learned about from listening to language, even if it’s not present in front of them.

Imagine a baby playing with blocks on the floor while listening to parents talk about kumquats, a novel fruit. Can the baby form an initial representation or “gist” about what kumquat means? The researchers sought to answer this question and more.

The study involved 134 infants, divided into two age groups: 12 months and 15 months. In a three-part task, babies were presented with words paired with images of familiar objects (e.g., apple, banana). Then, they heard a new word while an image of a novel object (e.g., kumquat) was hidden from their view.

The results showed that 15-month-olds looked longer at the novel fruit than the novel artifact, indicating that they had used context clues to identify which object was most likely the one referred to by the new word. This is significant because it suggests that even babies who are just beginning to say their first words can learn from language and form mental representations of objects and events never witnessed directly.

Waxman explained, “We’re asking whether infants, too, can use the conversational contexts in which a word occurs to begin to learn their meaning.” The study provides new insight into the developmental origins of the human capacity to learn about things that are not perceptually present.

The researchers’ findings highlight the power of language in infants’ daily lives. Babies often hear words that they don’t yet understand, and that they cannot “map” immediately to an object or event. However, this study shows that by 15 months, infants can spontaneously use linguistic context to build a gist of a new word’s meaning that will support subsequent learning.

As Waxman noted, “When we hear new words, like ‘kumquat’ in conversation when there are no kumquats around, we don’t waste the opportunity to home in its meaning. We now know this is also true about tiny babies.”
