Naturalistic Observations

18.2K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Environmental Influences on Intelligence

1.2K
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...

Group Design

11.1K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Cognitive Dissonance01:38

Cognitive Dissonance

38.0K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Social Facilitation

36.9K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Summary
This summary is machine-generated.

Delayed school entry (DSE) did not impact teacher-rated performance but was linked to lower standardized test scores in children. Missing a year of learning opportunities negatively affected academic achievement and attention.

Area of Science:

  • Developmental Psychology
  • Educational Psychology
  • Child Development

Background:

  • Emerging evidence suggests potential benefits of delayed school entry (DSE) for children with developmental delays.
  • However, existing research on the effects of DSE remains inconclusive.
  • This study addresses the need for clearer understanding of DSE's impact on academic and attentional development.

Purpose of the Study:

  • To investigate the effects of delayed school entry (DSE) compared to age-appropriate school entry (ASE).
  • To assess the impact of DSE versus ASE on academic achievement (mathematics, reading, writing) in middle childhood.
  • To evaluate the influence of DSE versus ASE on children's attention development.

Main Methods:

  • A prospective, population-based longitudinal study in Germany included 999 children (472 born preterm).
  • A natural experimental design with propensity score matching created comparable DSE and ASE groups.
  • Teacher ratings of academic performance and attention were collected in Year 1; standardized tests were administered at age 8.

Main Results:

  • No significant difference was found in teacher-rated above-average academic performance between DSE and ASE groups in Year 1.
  • Standardized test scores at age 8 were significantly lower for DSE children across all domains: mathematics, reading, writing, and attention.
  • Specific standardized mean score differences were observed: Mathematics (B=-0.28), Reading (B=-0.39), Writing (B=-0.90), and Attention (B=-0.58).

Conclusions:

  • Delayed school entry (DSE) did not influence teacher-assessed academic performance.
  • However, the loss of one year of learning opportunities was associated with poorer performance on standardized tests at age 8.
  • Further research is warranted to explore the long-term academic consequences of delayed school entry.
