Working memory in children assessed by the Brown-Peterson Task.

Area of Science:

• Cognitive Psychology
• Developmental Neuroscience
• Educational Psychology

Background:

• Working memory is crucial for language, reading, and writing development.
• Evaluating working memory in children aids early identification of learning impairments.

Purpose of the Study:

• To assess working memory development across early school grades.
• To determine the suitability of the Brown-Peterson Task for child assessment.

Main Methods:

• 103 children (1st-6th grade) were assessed.
• Utilized Brown-Peterson Task, Digit Span Forward, and Digit Span Backward.
• Compared results by gender, age, and grade level.

Main Results:

• Working memory scores improved with age and grade level.
• Performance decreased with longer interference intervals on the Brown-Peterson Task.
• The Brown-Peterson Task showed strong correlation with Digit Span and better differentiation across grades.

Conclusions:

• Working memory maturation extends through elementary education.
• The Brown-Peterson Task is a valid tool for assessing children's working memory.
