Age and task parameters in continuous performance tests for preschoolers

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Cognitive Psychology

Background:

• Continuous Performance Tests (CPTs) are vital for assessing attention in children.
• Understanding age-related differences in CPT performance is crucial for accurate assessment.
• Preschoolers' attentional abilities are still developing, making test design critical.

Purpose of the Study:

• To compare the performance of preschoolers on visual and auditory Continuous Performance Tests (CPTs).
• To investigate the impact of interstimulus interval (ISI) on CPT performance in young children.
• To examine age-related changes in reaction time, errors, and response variability.

Main Methods:

• Sixty-six preschoolers (ages 3-6) completed visual and auditory CPTs with single targets.
• Interstimulus intervals (ISIs) were fixed at 1350 ms (visual) and 5000 ms (auditory).
• Omission errors, commission errors, reaction time, and response variability were analyzed.

Main Results:

• Visual CPTs yielded higher omission and commission errors compared to auditory CPTs.
• Age correlated with reaction time and variability, but visual CPTs showed unexpected increasing response times with age.
• Omission errors decreased with age; commission errors remained stable across ages 3-6.

Conclusions:

• Visual CPTs may be more challenging for preschoolers than auditory CPTs due to higher error rates.
• Preschoolers, particularly 3-year-olds, may require longer ISIs (around 4000 ms) for optimal performance.
• Short ISIs (<1400 ms) might lead to responses based on previous stimuli, impacting accuracy.
