q2 i? Using the attention network task, adults with DD without comorbid attention disorders showed deficient alerting and executive attention while orienting attention was preserved. → Liane Kaufmann 2020

q2 · i? · causal · r?

Review reports Ashkenazi and Henik (2010) ANT-I study in adults with DD: "deficient alerting and executive attention" with preserved orienting. The authors attributed alerting difficulties to abnormal IPS functioning and executive deficits to possible prefrontal dysfunction.

"using the attention network task (ANT-I, Callejas, Lupianez, & Tudela, 2004) the authors reported deficient alerting and executive attention in adults with DD (in the presence of preserved orienting attention)."
