Verbal and spatial immediate memory span: normative data from 1355 adults and 1112 children

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Short-term memory assessment is crucial for diagnosing neurological disorders.
• Verbal and visuo-spatial memory spans are key indicators of cognitive function.
• Establishing normative data is essential for accurate clinical interpretation.

Purpose of the Study:

• To establish normative data for verbal and visuo-spatial immediate memory span.
• To investigate the effects of age, education, and sex on memory span in adults and children.

Main Methods:

• Collected data from 1355 adult subjects (20-99 years) and 1112 children (4-10 years).
• Administered verbal and visuo-spatial immediate memory span tasks.
• Analyzed data considering age, educational background, and sex.

Main Results:

• Adult memory span significantly decreases after age 60 and is affected by education.
• Adult males demonstrated superior performance on visuo-spatial tasks.
• In children, memory span increased with age, and boys outperformed girls in spatial tasks.

Conclusions:

• Age and education are critical factors influencing immediate memory span in adults.
• Sex differences in visuo-spatial memory emerge in both childhood and adulthood.
• These norms aid in the clinical evaluation of short-term memory and related neurological conditions.
