Old/New Effect of Digital Memory Retrieval in Chinese Dyscalculia: Evidence from ERP
Peer reviewed Peer reviewed
Direct linkDirect link
Wang, Enguo; Du, Chenguang; Ma, Yujun – Journal of Learning Disabilities, 2017
This study reports the neurophysiological and behavioral correlates of digital memory retrieval features in Chinese individuals with and without dyscalculia. A total of 18 children with dyscalculia (ages 11.5-13.5) and 18 controls were tested, and their event-related potentials were digitally recorded simultaneously with behavior measurement.…

Failing to Forget: Prospective Memory Commission Errors Can Result from Spontaneous Retrieval and Impaired Executive Control
Peer reviewed Peer reviewed
Direct linkDirect link
Scullin, Michael K.; Bugg, Julie M. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2013
Prospective memory (PM) research typically examines the ability to remember to execute delayed intentions but often ignores the ability to forget finished intentions. We had participants perform (or not perform; control group) a PM task and then instructed them that the PM task was finished. We later (re)presented the PM cue. Approximately 25% of…

Sleep Restores Daytime Deficits in Procedural Memory in Children with Attention-Deficit/Hyperactivity Disorder
Peer reviewed Peer reviewed
Direct linkDirect link
Prehn-Kristensen, Alexander; Molzow, Ina; Munz, Manuel; Wilhelm, Ines; Muller, Kathrin; Freytag, Damaris; Wiesner, Christian D.; Baving, Lioba – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Sleep supports the consolidation of declarative and procedural memory. While prefrontal cortex (PFC) activity supports the consolidation of declarative memory during sleep, opposite effects of PFC activity are reported with respect to the consolidation of procedural memory during sleep. Patients with attention-deficit/hyperactivity disorder (ADHD)…

Inhibitory Control of Memory Retrieval and Motor Processing Associated with the Right Lateral Prefrontal Cortex: Evidence from Deficits in Individuals with ADHD
Peer reviewed Peer reviewed
Direct linkDirect link
Depue, B. E.; Burgess, G. C.; Willcutt, E. G.; Ruzic, L.; Banich, M. T. – Neuropsychologia, 2010
Studies of inhibitory control have focused on inhibition of motor responses. Individuals with ADHD consistently show reductions in inhibitory control and exhibit reduced activity of rLPFC activity compared to controls when performing such tasks. Recently these same brain regions have been implicated in the inhibition of memory retrieval. The…

Neurocognitive Functioning in AD/HD, Predominantly Inattentive and Combined Subtypes
Peer reviewed Peer reviewed
Direct linkDirect link
Solanto, Mary V.; Gilbert, Sharone N.; Raj, Anu; Zhu, John; Pope-Boyd, Sa'brina; Stepak, Brenda; Vail, Lucia; Newcorn, Jeffrey H. – Journal of Abnormal Child Psychology, 2007
The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal…
