This book is divided into four main sections. The first section describes noninvasive measures of cerebral aging, including structural (e.g., volumetric MRI), chemical (e.g., dopamine PET), electrophysiological (e.g., ERPs), and hemodynamic (e.g., fMRI), and discusses how they can be linked to behavioral measures of cognitive aging. The second section reviews evidence for the effects of aging o...

Objective This review contemplates the recent consideration of social and affective factors within the study of cognitive aging and examines the multiple ways in which these factors intersect. Methods The article briefly reviews the models applied to cognitive aging and considers how they can inform the understanding of socioaffective aging. It then discusses the ways in which socioaffectiv...

OBJECTIVES Drawing on past studies of age identity, this article examined whether feeling older was associated with more pessimistic views about cognitive aging. METHODS Using respondents aged 55 years and older in the Midlife Development in the United States study, we estimated a series of linear regression models to predict people's dispositions toward their cognitive aging. The main compar...

Cognitive aging research and theory has, until recently, been based upon behavioral measures of cognitive performance such as response time and accuracy. Results from behavioral methodologies have indicated a general age-related decline in cognitive functions such as speed of processing, attention, perception, working memory, and cued and free recall—and age invariance when assessing cognitive ...

This commentary explores the relationships between the construct of successful aging and the experimental psychology of human aging-cognitive gerontology. What can or should cognitive gerontology contribute to understanding, defining, and assessing successful aging? Standards for successful aging reflect value judgments that are culturally and historically situated. Fundamentally, they address ...

Genes encoding mitochondrial ribosomal proteins (MRPs) have been linked to aging and longevity in model organisms (i.e., mice, Caenorhabditis elegans). Here we evaluated if the MRPs have conserved effects on aging traits in humans. We utilized data from 4,504 participants of the Women's Health Initiative Memory Study (WHIMS) who had both longitudinal cognitive data and genetic data. Two aging p...

neuropsychological studies have demonstrated that preclinical dementia accompanies a decreasing trend in cognitive state a few years prior to clinical diagnosis. sudden decline in episodic memory and semantic knowledge have been found to have the capability to differentiate patients in preclinical state of dementia from those experiencing normal aging. in addition, decline in episodic memory is...

Given the rapid rate of population aging and the increased incidence of cognitive decline and neurodegenerative diseases with advanced age, it is important to ascertain the determinants that result in cognitive impairment. It is also important to note that much of the aged population exhibit 'successful' cognitive aging, in which cognitive impairment is minimal. One main goal of normal aging st...

OBJECTIVE "Mild cognitive impairment" refers to cognitive deficits in older age that exceed age-related cognitive decline but do not fulfill criteria for dementia. Affected subjects are assumed to be at higher risk for the development of dementia, such as Alzheimer's disease. However, little is known about the group of young-old subjects with respect to the prevalence and natural course of cogn...
