Insights

Children with developmental coordination disorder (DCD) show significant cognitive deficits, particularly in executive function. Motor abilities in these children predict cognitive skills, with executive function being the primary area of concern.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Pediatrics

Background:

  • Children with developmental coordination disorder (DCD) frequently exhibit cognitive impairments, affecting memory, attention, and executive functions.
  • Understanding specific cognitive deficits in diverse populations, such as Chinese children, is crucial for targeted interventions.

Purpose of the Study:

  • To investigate the specific cognitive deficits in Chinese children diagnosed with DCD.
  • To explore the relationship between motor abilities and cognitive functions in children with and without DCD.

Main Methods:

  • Utilized the Movement Assessment Battery for Children (Movement ABC-2) to categorize 401 children (aged 7-10) in Guangdong Province, China, into DCD, at-risk, and control groups.
  • Administered various tests to assess cognitive abilities, including reaction time, memory, attention, and executive function.
  • Employed regression analysis to identify the primary cognitive deficits in children with DCD.

Main Results:

  • Overall motor abilities correlated with cognitive ability, reaction time, memory, and attention.
  • Children with DCD demonstrated slower reaction times compared to control groups.
  • The DCD group scored lower on executive function tasks than the normal control group.

Conclusions:

  • Cognitive deficits in Chinese children with DCD are predominantly linked to impaired executive function, rather than attention or memory.
  • Motor skills play a predictive role in cognitive development for children.
  • Findings offer preliminary insights for diagnosing and treating DCD in Chinese children.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Coordination Number and Geometry02:57

Coordination Number and Geometry

For transition metal complexes, the coordination number determines the geometry around the central metal ion. Table 1 compares coordination numbers to molecular geometry. The most common structures of the complexes in coordination compounds are octahedral, tetrahedral, and square planar.

Coordination Compounds and Nomenclature02:54

Coordination Compounds and Nomenclature

In most main group element compounds, the valence electrons of the isolated atoms combine to form chemical bonds that satisfy the octet rule. For instance, the four valence electrons of carbon overlap with electrons from four hydrogen atoms to form CH4. The one valence electron leaves sodium and adds to the seven valence electrons of chlorine to form the ionic formula unit NaCl (Figure 1a). Transition metals do not normally bond in this fashion. They primarily form coordinate covalent bonds, a...

Lattice Centering and Coordination Number02:33

Lattice Centering and Coordination Number

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Correlations02:20

Correlations

Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation01:27

Correlation and Causation

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...
