Introduction to Developmental Psychology

643
Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...

Binet's Contribution to Measures of Intelligence

1.4K
Alfred Binet, along with his student Théophile Simon, was tasked by the French Ministry of Education in 1904 to create a method for identifying students who struggled to learn through conventional classroom instruction. This initiative aimed to address overcrowding by placing such students in specialized schools. Binet and Simon developed an intelligence test comprising 30 tasks, ranging from simple commands, like touching one's nose or ear, to more complex tasks, such as drawing...

Introduction to z Scores

730
A z score (or standardized value) is measured in units of the standard deviation. It indicates how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

Measures of Intelligence01:29

Measures of Intelligence

7.9K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Range Rule of Thumb to Interpret Standard Deviation01:13

Range Rule of Thumb to Interpret Standard Deviation

9.7K
The range rule of thumb in statistics helps us calculate a dataset's minimum and maximum values with known standard deviation. This rule is based on the concept that 95% of all values in a dataset lie within two standard deviations from the mean.
For instance, the range rule of thumb can be used to find the tallest and the shortest student in a class, given the mean student height and standard deviation. If the mean student height is 1.6 m and the standard deviation, s is 0.05 m, the height...

Calculating Standard Deviation01:08

Calculating Standard Deviation

8.3K
The standard deviation is the most common measure of variation. It is a value that tells us how far a data value is from the mean value in a dataset. Further, the standard deviation is always a positive value or zero.
The standard deviation value is small when all the data is concentrated close to the mean. Here the data exhibits low variation. The standard deviation value is larger when the data values are more spread out from the mean. Here, the data displays high...

Summary
This summary is machine-generated.

This study established new developmental norms for children aged 0-6 years using the Tipat Halav Israel Screening (THIS) Developmental Scale, based on the largest population cohort to date. The THIS scale offers updated developmental milestones for early detection of delays.

Related Experiment Videos

Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Public Health

Background:

  • Routine developmental screening is crucial for early detection of delays, but current norms lack robust data and exhibit inconsistencies across tools.
  • Existing developmental screening tools show variability, highlighting the need for updated and reliable normative data.

Purpose of the Study:

  • To establish updated developmental milestone norms for children.
  • To develop a contemporary developmental scale, the Tipat Halav Israel Screening (THIS) Developmental Scale.

Main Methods:

  • A population-based, cross-sectional study conducted in Israel from 2014-2020, involving developmental assessments of children from birth to 6 years.
  • Utilized data from 643,958 children and 3,774,517 assessments, with trained public health nurses documenting milestones in national maternal child health clinics.
  • Established the THIS Developmental Scale by calculating 75%, 90%, and 95% milestone achievement rates and compared it with existing tools like Denver II, AIMS, and CDC Developmental Assessment.

Main Results:

  • The study established new developmental norms for 59 milestones across 4 domains, based on a large cohort of 643,958 children.
  • The THIS Developmental Scale demonstrated high concordance with the Alberta Infant Motor Scale (AIMS) (100%) and moderate agreement with the Denver Developmental Screening Test II (Denver II) (67%) and CDC Developmental Assessment (53%).
  • Unmatched milestones in the THIS scale were generally achieved earlier than in other screening tools, indicating updated normative data.

Conclusions:

  • The THIS Developmental Scale, derived from the largest population cohort to date, provides contemporary developmental norms for a diverse population.
  • The scale's robust normative data and comparison with existing tools suggest its utility for early detection of developmental delays.
  • The THIS scale is recommended for further international evaluation due to its comprehensive dataset and representation of a multicultural population.
