Effects of day care on cognitive development

Positive effects on cognitive development

• Improved academic performance - Children in high-quality day care often show better language abilities and higher scores in reading and maths compared to those who have never attended day care.
• Benefits for disadvantaged children - For preschool children from less stimulating home environments, day care can provide essential opportunities for cognitive growth.

Negative effects on cognitive development

• Lower skills in early starters - Children placed in day care before the age of three may develop poorer reading and maths skills.
• Insecure attachment impacting exploration - Day care might create 'insecure' children who lack a secure base for confident exploration, which may hinder cognitive development.
• Reduced stimulation leading to passivity - Quiet behaviour is rewarded, which can encourage passive, under-stimulated children, leading to poorer cognitive outcomes.

Effects of day care on social development

Positive effects on social development

• Enhanced sociability and popularity - Children who attend day care often become more sociable and popular when they start school.
• Better coping in social situations - Day care can foster independence and helpfulness, helping children cope better in social situations. They may develop negotiation skills.
• Increased opportunities for interaction - Being in day care exposes children to diverse peers, promoting skills like turn-taking and empathy.

Negative effects on social development

• Increased insecure attachment - Children in day care may show more signs of insecure attachment, such as greater distress during separations, as observed in the Strange Situation. Separation can affect a child's attachment by disrupting their continuous relationship with a caregiver.
• Heightened aggression - The longer children spend in day care, the more aggressive they may become.

Factors influencing the effects of day care

Research indicates that the impact of day care is not straightforward and varies based on several factors. These include the child's home environment, the quality of the day care, the duration and timing of attendance, and whether effects are measured in the short or long term.

Quality of home life and compensatory effects

The child's attachment style at home interacts with day care experiences. For securely attached children, day care may have negative effects by separating them from high-quality home care. In contrast, insecurely attached children often benefit, as day care provides compensatory care, leading to positive outcomes.

Type and quality of day care

The structure and resources in day care settings are crucial. Key elements include staffing and stimulation levels.

Staffing considerations:

• Nursery care - Often features qualified staff and stimulating environments but may have lower staff-to-child ratios and higher staff turnover, limiting opportunities for children to form stable attachments.
• Childminders - Many in the UK are unregistered with Ofsted (in England) or equivalent regulatory bodies, and research shows unregistered childminders frequently provide poor care, which can negatively affect development.

Day care can sometimes offer less stimulation than home, especially if caregivers reward quiet behaviour, leading to passive children. However, high-quality day care may provide more stimulation, particularly for disadvantaged children.

Duration and timing of day care

• Hours per week - Children spending more than 20 hours per week in day care are more likely to develop insecure attachments, as seen in assessments like the Strange Situation. Those exceeding 10 hours per week may show increased aggression at school age, possibly due to attachment issues.
• Age of entry - Negative effects are most common when day care starts in the child's first year. There is little evidence of harm for older children starting day care.
• Short-term vs long-term effects - Initial problems, such as emotional distress at ages three or four, often resolve by age 12, suggesting no permanent harm from day care.

Key research studies examining day care outcomes

The EPPE Study (Effective Provision of Pre-School Education)

The EPPE study is a longitudinal research project that followed over 3,000 children from age 3 to 16, examining the effects of different types of pre-school provision on children's development.

Key findings:

• High-quality pre-school education benefits all children, with particularly strong effects for disadvantaged children
• The quality of pre-school provision is more important than the type of provision
• Children who attended high-quality pre-school settings showed better academic and social outcomes throughout their school years
• The benefits of high-quality early education persist into secondary school

NICHD Study of Early Child Care

This large-scale American study followed over 1,300 children from birth to age 15, examining the effects of various forms of child care on development.

Key findings:

• Quality of care is more important than type of care for children's development
• Children in high-quality care showed better language and cognitive development
• Extensive early child care (more than 30 hours per week before age 1) was associated with increased assertiveness and aggression
• The effects of early child care were still evident at age 15, though they were relatively small compared to family influences
