Insights

Infants with Down syndrome showed that attention shifting ability is linked to cognitive development. Premature birth may negatively impact attention skills in these children.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Pediatrics

Background:

  • Cognitive development delays are apparent in early childhood for individuals with Down syndrome.
  • The underlying neuropsychological and biomedical factors influencing cognitive skill acquisition in Down syndrome are not well understood.

Purpose of the Study:

  • To investigate the relationship between specific cognitive skills and overall cognitive development in infants with Down syndrome.
  • To identify potential early indicators and risk factors for cognitive skill acquisition challenges in this population.

Main Methods:

  • 38 infants with Down syndrome (mean age 9.65 months) were assessed using the Bayley Scales of Infant Development-III.
  • Laboratory tasks evaluated sustained attention, attention shifting, and visual short-term memory.

Main Results:

  • A negative association was found between attention shifting latency and Bayley Cognitive Scale scores (r = -.41, P = .02), even after controlling for chronological age.
  • Prematurity status was significantly associated with longer latency in attention shifting.

Conclusions:

  • Early attention shifting skills appear crucial for facilitating cognitive skill acquisition in infants with Down syndrome.
  • Premature birth may represent a risk factor for deficits in attention shifting abilities within this group.

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...

Cognitive Dissonance01:38

Cognitive Dissonance

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...

Correlation01:09

Correlation

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Correlation and Regression00:53

Correlation and Regression

In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a...
