    • Age-Related Differences in Attention to Novelty Among Cognitively High Performing Adults 

      Daffner, Kirk R.; Ryan, Katherine K.; Williams, Danielle M.; Budson, Andrew E.; Rentz, Dorene May; Wolk, David A.; Holcomb, Phillip J.; Ryan, Katherine (Elsevier BV, 2006)
      Age-related differences in attention to novel events were studied in well-matched, cognitively high performing old, middle-aged and young subjects. Event-related potentials were recorded during a visual novelty oddball ...

    • The central role of the prefrontal cortex in directing attention to novel events 

      Daffner, Kirk R. (Oxford University Press (OUP), 2000)
      The physiological basis for the striking decrease of attention to novel events following frontal lobe injury is poorly understood. In this study, event-related potentials (ERPs) were recorded from patients with frontal ...

    • Changes in Neural Activity Underlying Working Memory after Computerized Cognitive Training in Older Adults 

      Tusch, Erich S.; Alperin, Brittany R.; Ryan, Eliza; Holcomb, Phillip J.; Mohammed, Abdul H.; Daffner, Kirk R. (Frontiers Media S.A., 2016)
      Computerized cognitive training (CCT) may counter the impact of aging on cognition, but both the efficacy and neurocognitive mechanisms underlying CCT remain controversial. In this study, 35 older individuals were randomly ...

    • Does compensatory neural activity survive old-old age? 

      Daffner, Kirk R.; Sun, Xue; Tarbi, Elise C.; Rentz, Dorene May; Holcomb, Phillip J.; Riis, Jenna L. (Elsevier BV, 2011)
      One mechanism that may allow older adults to continue to successfully perform certain cognitive tasks is to allocate more resources than their younger counterparts. Most prior studies have not included individuals beyond ...
