  1. Delaying interference enhances memory consolidation in amnesic patients.

    Neuropsychology 23(5):627 (2009) PMID 19702416 PMCID PMC2808210

    Some patients with amnesia are able to retain new information for much longer than expected when the time that follows new learning is devoid of further stimuli. Animal work shows that the absence or delaying of interference improves long-term memory consolidation. Our study suggests that this i...
  2. A meta-analytic investigation of neurocognitive deficits in bipolar illness: profile and effects of clinical state.

    Neuropsychology 23(5):551 (2009) PMID 19702409 PMCID PMC2804472

    A meta-analysis of neuropsychological studies of patients with bipolar disorder comprised of 42 studies of 1,197 patients in euthymia, 13 studies consisting of 314 patients in a manic/mixed phase of illness, and 5 studies of 96 patients in a depressed state. Cohen d values were calculated for ea...
  3. Selectivity of executive function deficits in mild cognitive impairment.

    Neuropsychology 23(5):607 (2009) PMID 19702414 PMCID PMC2769993

    Impairment in executive cognition (EC) is now recognized as relatively common among older persons with mild cognitive impairment (MCI) and may be predictive of the development of dementia. However, both MCI and executive functioning are broad and heterogeneous constructs. The present study sough...
  4. Semantic inhibition impairment in mild cognitive impairment: a distinctive feature of upcoming cognitive decline?

    Neuropsychology 23(5):592 (2009) PMID 19702413

    This study aimed to measure semantic inhibitory capacities in persons with a diagnosis of Alzheimer's disease (AD) or mild cognitive impairment (MCI), in healthy older and younger adults. This was done by relying on a computerized adaptation of the Hayling task, designed to diminish the likeliho...
  5. Implicit false memory in the DRM paradigm: effects of amnesia, encoding instructions, and encoding duration.

    Neuropsychology 23(5):635 (2009) PMID 19702417

    Recent studies with the Deese/Roediger-McDermott (Deese 1959; Roediger & McDermott, 1995) paradigm have revealed that amnesic patients do not only show impaired veridical memory, but also diminished false memory for semantically related lure words. Due to the typically used explicit retrieval in...
  6. A longitudinal analysis of cognitive dysfunction, coping, and depression in multiple sclerosis.

    Neuropsychology 23(5):581 (2009) PMID 19702412

    Using a longitudinal design, the authors examined coping and cognitive functioning in the development of depression in individuals with multiple sclerosis (MS). Coping style was evaluated in 2 conceptually distinct roles: as moderator and mediator of the impact of cognitive dysfunction on depres...
  7. The prevalence of cortical gray matter atrophy may be overestimated in the healthy aging brain.

    Neuropsychology 23(5):541 (2009) PMID 19702408

    Prevailing opinion holds that normal brain aging is characterized by substantial atrophy of cortical gray matter. However, this conclusion is based on earlier studies whose findings may be influenced by the inclusion of subjects with subclinical cognitive disorders like preclinical dementia. The...
  8. Testing possible mechanisms of deficient supra-second time estimation in adults with attention-deficit/hyperactivity disorder.

    Neuropsychology 23(5):679 (2009) PMID 19702421

    Numerous studies indicate deficient time estimation in individuals with attention-deficit/hyperactivity disorder (ADHD). Several hypotheses have been raised to explain this deficit including delay aversion, vulnerability to nontemporal distractions, deficient working memory, as well as pure defi...
  9. Frontotemporal dementia selectively impairs transitive reasoning about familiar spatial environments.

    Neuropsychology 23(5):619 (2009) PMID 19702415 PMCID PMC2981035

    Although patients with frontotemporal dementia (FTD) are known to exhibit a wide range of cognitive and personality difficulties, some evidence suggests that there may be a degree of selectivity in their reasoning impairments. Based on a recent review of the neuroimaging literature on reasoning,...
  10. ERPs in anterior and posterior regions associated with duration and size discriminations.

    Neuropsychology 23(5):668 (2009) PMID 19702420

    The main objective of the present study was to determine whether event-related potentials (ERPs) predominant in prefrontal cortex (PFC) respond in a similar fashion to ERPs predominant in posterior parietal cortex (PPC) in duration and size discrimination tasks. The results indicate that conting...
