For many years, acquisition of verbal morphology has been an issue of much debate within linguistic theory, research on first and second language acquisition, mental grammar representation, and cognitive processing. The proponents of the Dual Mechanism account claim that regularly inflected forms are computed by a ruleprocessing system, while morphologically irregular forms are processed in ass...

We review work on the effectiveness of different forms of cognitive enhancement, both pharmacological and non-pharmacological. We consider caffeine, methylphenidate, and modafinil for pharmacological cognitive enhancement (PCE) and computer training, physical exercise, and sleep for non-pharmacological cognitive enhancement (NPCE). We find that all of the techniques described can produce signif...

There is a strong association between late-life depression, cognitive impairment, cerebrovascular disease, and poor cognitive outcomes, including progressive dementia, especially Alzheimer's disease. While neuroimaging evidence suggests that cerebrovascular disease plays a prominent role, it seems that depression alone may also confer substantial risk for developing Alzheimer's disease. The rel...

This study examined the maintenance of retest learning benefits in young old and oldest old adults over an 8-month period in 3 cognitive abilities: reasoning, perceptual-motor speed, and visual attention. Twenty-four young old (aged 70-79 years, M = 74.2) and 23 oldest old adults (aged 80-90 years, M = 83.6) who participated in a previously published study (Yang, L., Krampe, R. T., & Baltes, P....

Individuals regulate their emotions in a wide variety of ways. In the present review it has been addressed the issue of whether some forms of emotion regulation are healthier than others by focusing on two commonly used emotion regulation strategies: cognitive reappraisal (changing the way one thinks about potentially emotion-eliciting events) and expressive suppression (changing the way one be...

In this study, the authors examined whether cognitive therapy alters the association between negative cognition and symptoms of depression. Participants were recruited during psychiatric hospitalization for depression. Following discharge, they were randomly assigned to 6 months of outpatient treatment. Treatment consisted of pharmacotherapy either alone or in combination with cognitive therapy...

In this article, we briefly summarize the incidence and significant consequences of falls among older adults, the insufficient effectiveness of commonly used multifactorial interventions and the evidence linking falls and cognitive function. Recent pharmacologic and nonpharmacologic studies that evaluated the effects of cognitive therapy on fall risk are reviewed. The results of this article il...

Contemporary theories of language production disagree about the cognitive mechanisms involved in the production of past tense forms of regular and irregular verbs. Two models compete to explain this process: Dual-route and Single-route. The present study tests these models using previously reported methods of production and naturalness rating of the past tense forms of novel verbs. Overall, par...

OBJECTIVE The diagnosis of mild cognitive impairment (MCI) and dementia requires detailed neuropsychological examinations. These examinations typically yield a large number of outcome variables, which may complicate the interpretation and communication of results. The purposes of this study were the following: (i) to reduce a large data set of interrelated neuropsychological variables to a smal...
