q3 i? Children found a mean of 30.1 bells (SD = 3.0) and ADHD score showed no relation to visual search performance. → Van den Driessche 2019

q3 · i? · associational · r2

Performance analysis in the same Bells Test study of 87 children: mean 30.1 bells (SD = 3.0) with "No difference were found depending on ADHD score (p > 0.7)"; equivalence was not tested and no effect size was printed.

"Children found a mean of 30.1 (SD = 3.0) bells within two minutes. No difference were found depending on ADHD score (p > 0.7)."

Discussion¶

Related Claims¶

• Children with higher ADHD rating-scale scores make longer transitions between consecutively retrieved items in a visual search task
• Exploratory search behaviour in visual and semantic tasks is not correlated across children once ADHD score is controlled
• The exploration advantage in semantic search is interpreted as context-dependent, potentially beneficial in sparsely distributed target environments
• Higher ADHD scores increase the variability of semantic search paths via more long-distance jumps, but not mean semantic distance
• Higher ADHD rating-scale scores predict better semantic fluency performance and more immediate repetitions in children — related
• Under normal conditions children with ADHD show deficits in vigilance, visual search and divided attention relative to TD children — reports the opposite
