The aim of the paper was to study the intellectual profile of 94 gifted elders aged 60-90 years old with an IQ equal to or higher than 130 on at least one of the four primary indexes of the Wechsler Adult Intelligence Scale -- Fourth Edition. Their performances in the 15 subtests, in the Full Scale Intelligence Quotient, in the primary,…

Two experiments are presented that use tasks common in research in numerical cognition with young adults and older adults as subjects. In these tasks, one or two arrays of dots are displayed, and subjects decide whether there are more or fewer dots of one kind than another. Results show that older adults, relative to young adults, tend to rely…

This study aimed to compare cognitive and memory abilities between older adults with and without autism over the age of 50. Twenty-eight individuals with autism and 29 typically developing (TD) older adults took part in the current study. Participants' cognitive and memory abilities were assessed by WAIS-IV and WMS-IV. Older autistic adults were…

Enhancing the cognitive functionality of digital technology can be critical in learning complex topics like caregiving for older adults. This study examines the deployment of cognitive prompts in video-based training to optimize older adults' cognitive information process in both deep and surface learning. The path analysis revealed the…

Although hearing often declines with age, prior research has shown that older adults may benefit from multisensory input to a greater extent when compared to younger adults, a concept known as inverse effectiveness. While there is behavioral evidence in support of this phenomenon, less is known about its neural basis. The present functional MRI…

Purpose: As pulse rate increases beyond a few hundred Hertz, younger normal-hearing (NH) participants' ability to encode temporal information in band-limited acoustic pulse trains decreases, demonstrating a rate limitation in processing rapid temporal information. Rate discrimination abilities, however, have yet to be investigated in older NH…

In a Yes/No object recognition memory test with similar lures, older adults typically exhibit elevated rates of false recognition. However, the contributions of impaired retrieval, relative to reduced availability of target details, are difficult to disentangle using such a test. The present investigation sought to decouple these factors by…

The purpose of the study was to test a model of causal relationships among cognitive reserve (CR), personality variables such as Neuroticism and Openness to experience, and divergent thinking (DT), independently evaluating performance in different domains (verbal and graphic). It was hypothesized that CR, Openness, and Neuroticism would each…

Having a sense of purpose is recognized as an important resource for maintaining health and well-being over the life span. We examined associations of individual differences in sense of purpose with levels and rates of change in indices of aging well (health, cognition, and depressive symptoms) in a sample of 1,475 older adults (M[subscript age] =…

The rate at which people process information appears to influence many aspects of cognition across the lifespan. However, many commonly accepted measures of "processing speed" may require goal maintenance, manipulation of information in working memory, and decision-making, blurring the distinction between processing speed and executive…

This study applied volumetric analysis and voxel-based morphometry (VBM) of brain magnetic resonance (MR) images to assess whether correlations exist between global and regional gray/white matter volume and the cognitive functions of semantic memory and short-term memory, which are relatively well preserved with aging, using MR image data from 109…

Two experiments on divided attention and adult aging are reported that take into account age differences in single-task performance and that measure divided attention independently of resource allocation strategies. No significant age difference in divided attention ability independent of single-task performance level was found in either…

With 101 healthy aging adult participants, the authors investigated whether executive functions are a unitary concept. The authors established the factor structure of the Wisconsin Card Sorting Test (WCST; E. A. Berg, 1948), the Stroop color and word test (C. J. Golden, 1978), verbal fluency using the Controlled Oral Word Association Test (COWAT;…
