Cognitive gerontology research requires consideration of performance as well as perceptions of performance. While subjective memory is positively associated with memory performance, these correlations typically are modest in magnitude, leading to the need to consider whether certain people may show weaker or stronger linkages between performance and perceptions. The current study leveraged personality (NEO Big Five), memory performance (i.e., word recall), and perceptions of memory ability (i.e., metamemory in adulthood and memory decline) data from the St. Louis Personality and Aging Network (SPAN) study ( = 774, mean age: 71.52 years). Extraversion and conscientiousness held the most consistent associations with the cognitive variables of interest, as both traits were positively associated with metamemory and word recall, but negatively associated with subjective decline. Moreover, extraversion moderated associations between word recall and both memory capacity and complaints, insofar that objective-subjective associations were weaker for those adults higher in extraversion. These findings highlight the need to understand how personality influences the sources of information employed for subjective cognitive beliefs.

Over the past few decades, Swahili-English and Lithuanian-English word pair databases have been extensively utilized in research on learning and memory. However, these normative databases are specifically designed for generating study stimuli in learning and memory research involving native (or fluent) English speakers. Consequently, they are not suitable for investigations that encompass populations whose first language is not English, such as Chinese individuals.

Background: Subjective Cognitive Complaints (SCCs) can often precede mild cognitive impairment and dementia longitudinally. While increasingly considered an early prodromal stage of dementia, SCCs can also be a symptom of depression. Previous research found that SCCs in the absence of cognitive impairment, controlling for symptoms of depression, were moderately heritable and genetically associated with memory.

Background: Optimal cerebral blood flow is crucial to maintaining cognitive function. Cerebrovascular reactivity (CVR) is a dynamic measure of cerebrovascular function which represents the ability of cerebral blood vessels to regulate blood flow in response to vasoactive stimuli. Prior studies have demonstrated an association between impaired CVR and cognitive function in cerebrovascular and neurodegenerative conditions, including cerebral amyloid angiopathy and Alzheimer disease.

Background: Mild cognitive function (MCI) is associated with a declined short-term memory (STM). This study compared STM between adults with MCI and normal cognition assessed by verbal memory vs visuospatial memory.
Methods: Sixteen subjects with MCI and 11 subjects with normal cognition gave their written consent to participate in the study which was approved by the North Texas Regional IRB.

Background: Neuropsychiatric symptoms (NPS) are common in early stages of Alzheimer's disease (AD) and may be early markers of cognitive decline and dementia in older individuals. The Mild Behavioral Impairment Checklist (MBI-C) was developed to capture new-onset transdiagnostic NPS in individuals at risk of dementia. We sought to determine whether mild behavioral impairment symptoms are elevated in non-demented Presenilin-1 (PSEN1) E280A carriers, who are genetically determined to develop dementia by their 50s.
