NurtureShock

1. Praise effort, not intelligence, to foster resilience and growth

"When we praise children for their intelligence," Dweck wrote in her study summary, "we tell them that this is the name of the game: look smart, don't risk making mistakes."

Fixed vs. growth mindset. Praising children for being smart can inadvertently create a fixed mindset, where they believe intelligence is innate and unchangeable. This leads to fear of failure and avoidance of challenges. In contrast, praising effort and perseverance cultivates a growth mindset, encouraging children to embrace challenges and view failures as learning opportunities.

Impact on performance. Studies show that children praised for intelligence perform worse on subsequent tasks compared to those praised for effort. When faced with difficulty, "smart" kids often give up, while "hard-working" kids persist and improve. This difference in attitude can have long-lasting effects on academic achievement and personal development.

Key behaviors to encourage:

• Embracing challenges
• Persisting in the face of setbacks
• Seeing effort as the path to mastery
• Learning from criticism
• Finding lessons and inspiration in others' success

2. Sleep deprivation significantly impairs children's cognitive development

"A loss of one hour of sleep is equivalent to [the loss of] two years of cognitive maturation and development," Sadeh explained.

Academic performance. Sleep deprivation has a profound impact on children's cognitive abilities. Studies show that even a small reduction in sleep can lead to significant drops in academic performance, equivalent to a child performing two grade levels below their actual grade.

Long-term consequences. Chronic sleep deprivation in children is linked to:

• Decreased attention span and focus
• Impaired memory consolidation
• Increased risk of obesity and diabetes
• Higher rates of anxiety and depression
• Behavioral problems and ADHD-like symptoms

To combat this, parents and schools should prioritize healthy sleep habits, including consistent bedtimes, screen-free wind-down routines, and later school start times for adolescents.

3. Discussing race openly with children promotes healthy attitudes

"I think it is fair to say that at no point in the study did the children exhibit the Rousseau-type of color-blindness that many adults expect."

Early awareness. Children notice racial differences from a very young age, typically around 6 months old. By age 3-5, they have already begun to form racial attitudes and biases. Ignoring these observations or adopting a "colorblind" approach does not prevent the development of prejudice.

Open dialogue. Instead of avoiding the topic, parents and educators should:

• Acknowledge and discuss racial differences openly
• Provide positive examples of diversity and inclusion
• Address stereotypes and prejudices directly
• Encourage cross-racial friendships and experiences

By fostering open conversations about race, adults can help children develop healthy, inclusive attitudes and combat the formation of unconscious biases.

4. Children's lying is a sign of cognitive development, not moral failure

"It's a developmental milestone," Talwar has concluded.

Cognitive complexity. Lying requires advanced cognitive skills, including:

• Understanding another person's perspective
• Creating and maintaining an alternative reality
• Verbal and non-verbal control to sell the lie

As such, the ability to lie effectively often correlates with higher intelligence and social skills in children.

Parental response. Rather than focusing solely on punishment, parents should:

• Recognize lying as a normal part of development
• Create an environment where truth-telling feels safe
• Praise honesty and reinforce its importance
• Model truthful behavior themselves

By understanding the developmental aspects of lying, parents can guide children towards honesty while fostering their cognitive and social growth.

5. Early IQ tests poorly predict long-term academic potential

"Going to integrated schools gives you just as many chances to learn stereotypes as to unlearn them."

Limited predictive value. IQ tests administered to young children (preschool to early elementary) have surprisingly low correlations with later academic achievement. This is due to the rapid and uneven development of children's brains during these years.

Brain plasticity. Key factors affecting cognitive development include:

• Myelination of neural pathways
• Pruning of unused synapses
• Shifts in brain regions used for different tasks

These processes continue well into adolescence, making early assessments unreliable for long-term predictions.

Instead of relying heavily on early IQ tests, educators and parents should focus on providing rich, stimulating environments and diverse learning opportunities throughout childhood and adolescence.

6. Sibling relationships shape social skills more than parental influence

"Fantasy play represents one of the highest levels of social involvement for young children."

Peer-like interactions. Sibling relationships provide a unique context for developing social skills, as they involve more peer-like interactions than parent-child relationships. These interactions foster skills such as:

• Conflict resolution
• Negotiation
• Empathy
• Emotional regulation

Long-term impact. The quality of sibling relationships in childhood is a strong predictor of social competence in adulthood. Positive sibling interactions teach children how to navigate complex social situations and maintain long-term relationships.

Parents can support healthy sibling relationships by:

• Encouraging cooperative play
• Teaching conflict resolution skills
• Avoiding comparisons between siblings
• Providing opportunities for shared experiences

7. Teenage rebellion is often a sign of respect, not disrespect

"The popular image of the individual sulking in the wake of a family argument may be a more accurate portrayal of the emotional state of the parent, than the teenager."

Negotiating autonomy. Teenage rebellion is often a way for adolescents to assert their growing independence and negotiate new boundaries. Arguing with parents can be seen as a sign of engagement and a desire for mutual understanding, rather than pure defiance.

Productive conflict. Research shows that moderate levels of parent-teen conflict are associated with better adjustment than either no conflict or frequent conflict. Productive arguments can:

• Improve communication skills
• Develop critical thinking
• Foster emotional intelligence
• Lead to more balanced family dynamics

Parents can support this process by:

• Listening actively to teens' perspectives
• Being willing to negotiate and compromise
• Setting clear, reasonable boundaries
• Modeling respectful disagreement

8. Self-control in early childhood predicts later success

"Self-control can be as powerful, and at times more powerful, than IQ."

Marshmallow test. The famous "marshmallow test" and subsequent longitudinal studies have shown that children who can delay gratification at a young age tend to have better life outcomes, including:

• Higher academic achievement
• Better social skills
• Lower rates of substance abuse
• Higher income in adulthood

Teachable skill. Self-control is not fixed; it can be taught and improved. Effective strategies include:

• Breaking large tasks into smaller, manageable steps
• Using visual aids to track progress
• Practicing mindfulness and meditation
• Creating environments that support good habits

By fostering self-control in early childhood, parents and educators can set children up for long-term success across various life domains.

9. Aggression in children can be a tool for social dominance

"Aggression comes as 'early adolescents are discovering themselves. They're learning about coolness—how to be attractive to other people.'"

Social strategy. Contrary to popular belief, aggression in children is often not a sign of poor social skills, but a strategic tool for gaining social status. "Popular" children frequently use a mix of prosocial and aggressive behaviors to maintain their position.

Types of aggression:

• Physical (hitting, pushing)
• Verbal (insults, threats)
• Relational (exclusion, gossip)

Addressing aggression. Instead of focusing solely on eliminating aggressive behaviors, adults should:

• Teach children alternative ways to assert themselves
• Foster empathy and perspective-taking
• Promote inclusive social environments
• Recognize and reward prosocial leadership behaviors

By understanding the social functions of aggression, parents and educators can more effectively guide children towards positive social interactions.

10. Language development depends on responsive parent-child interactions

"When parents see development in their kids, they are only seeing the output—not the mechanisms underneath."

Responsive interactions. The key to early language development is not the sheer volume of words a child hears, but the quality of back-and-forth interactions with caregivers. Responsive parenting involves:

• Noticing and responding to a child's vocalizations
• Engaging in "serve and return" conversations
• Using gestures and facial expressions to enhance communication
• Following the child's lead in topics of interest

Critical periods. Language development is most rapid in the first few years of life. During this time, children's brains are particularly receptive to linguistic input. Key milestones include:

• Babbling (6-8 months)
• First words (12-18 months)
• Two-word combinations (18-24 months)
• Complex sentences (3-5 years)

Parents can support language development by creating a rich, interactive linguistic environment, focusing on quality interactions rather than rote repetition or passive exposure to language.
