Children’s Block Design broken configurations are common but usually self-corrected. Frequent errors indicate weaker visuospatial skills and less influence from global spatial properties.

Area of Science:

Neuroscience
Developmental Psychology
Cognitive Psychology

Background:

The Block Design (BD) task is a key component of intelligence assessments.
Understanding errors in BD, like broken configurations, offers insight into visuospatial processing.
Children's cognitive development influences their performance on spatial tasks.

Purpose of the Study:

To investigate the clinical significance of broken configurations in children's Block Design performance.
To explore the cognitive underpinnings of these specific errors.
To determine the relationship between broken configurations and visuospatial skills.

Main Methods:

Two experiments were conducted with 336 children aged 6–14 years.
Participants completed the WISC-III Block Design (BD) test.

Experiment 2 included a global-local similarity judgment task to assess perceptual bias.

Main Results:

Broken configurations were common but typically self-corrected.
A higher frequency of broken configurations correlated with lower overall BD scores and lower maternal education.
Broken configurations were more prevalent in designs with high perceptual cohesiveness and in children with less global perceptual bias.

Conclusions:

While occasional broken configurations are normal, a high frequency suggests weaker visuospatial abilities.
Perceptual processing, specifically global bias, plays a role in the occurrence of broken configurations.
These findings enhance the understanding of visuospatial development and assessment in children.
