For example, older adults tend to show more deficits on tests of free recall, to a somewhat lesser degree of difficulty in cued recall, and minimal difficulty in recognition memory. The most susceptible to brain damage and the most affected by normal aging is episodic memory. Although many older adults complain of increased memory lapses as they age not all kinds of memory are affected by normal ageing. Considerable evidence, from both behavioral and neurobiological sources, suggests that the basic cognitive domains most affected by age are executive function and memory. Subjective cognitive decline (SCD) is a common complaint of the elderly population and may also be the earliest manifestation of Alzheimer or other forms of dementia. For others, cognitive decline is associated with severe cognitive deficits that impede the ability to live independently (i.e., Dementia). For some, cognitive changes are serious enough to be noticed by other people and confirmed by neuropsychological tests while these changes still do not interfere with daily life or independent function (i.e., Mild Cognitive Impairment). processing speed, attention, working memory, cognitive flexibility, and episodic memory), considered normal within the spectrum of typical cognitive aging. For many people cognitive decline is associated with relatively minor and sporadic cognitive difficulties (e.g. Generally, it is difficult to separate normal cognitive aging from pathological cognitive decline. While a life expectancy beyond 60 years of age has increased by about 25 years, only the first 18 years of this period are likely to be spent in good health, including good cognitive functioning. In Canada, for example, 22.3% of the population is currently over 60 years old, and this is estimated to increase to 32.5% by 2050. North America has a growing aging population that will introduce unique challenges for the health care system in the coming century. Subjective cognitive decline, Perceptual-cognitive training, NeuroTracker, Memory, Processing speed, Cognitive flexibility, Working memory Furthermore, higher scores in memory performance were related to faster processing speeds.Ĭonclusion: These data suggest that PCT may serve as a proactive intervention to enhance memory, working memory and cognitive flexibility in older adults with SCD. Within the treatment group the PCT scores of the last session were also significantly correlated with processing speed and cognitive flexibility. Results: The results indicate a significant difference between groups at T1 and T2, wherein the treatment group has improved scores in memory tasks (e.g., CVLT-II: Immediate Free Recall Short-Term Memory Recall, and Long-Term Memory Recall), working memory task (e.g., Digit Span Backward) and cognitive flexibility task (e.g., D-KEFS Verbal Fluency Category Switching and D-KEFS Verbal Fluency Letter Fluency). Four weeks after the completion of the PCT, a third assessment (T3) was performed to determine the veracity and persistence of any PCT benefits on cognitive performance. The second assessment (T2) was performed immediately after either seven weeks of PCT (treatment group), or after seven weeks of no training (control group). The first assessment was prior to the PCT (T1). All the participants were asked to complete three neuropsychological assessments over a three-month period. Method: Forty-seven subjects aged 60–90 years of age were assigned to control and treatment groups using a randomised controlled trial. The aim of this study was to determine if perceptual-cognitive training (PCT) can serve as a proactive intervention and enhance cognition in older adults with SCD. There are 30 trials in this experiment.Introduction: Subjective cognitive decline (SCD) in older adults are an early risk indicator for Alzheimer’s disease or other forms of dementia, making older adults with SCD a target population for proactive interventions.

If incorrect, the digits spoken per trial will decrease to a minimum of one. If participants enter the correct answer the amount of digits per trial increases. Remember them in order and type them with no spaces on the next screen and press Enter when complete.

In this experiment a voice speaks a series of numbers in each trial. The first trial begins with a string of three digits. It gives sets of 5 trials on a set of digits, starting with a length of 3, moving up or down depending on performance (3+ correct makes the number of digits increase, 2-makes it decrease). It's tunable as far as number of blocks and duration of stimuli are concerned. This script allows determination of an individual's auditory digit span.
