Assessments of cognitive and verbal functions are widely used as screening tests to detect early dementia. This study developed an early dementia prediction model for Korean elderly based on random forest algorithm and compared its results and precision with those of logistic regression model and decision tree model. Subjects of the study were 418 elderly (135 males and 283 females) over the ag...

OBJECTIVE To assess patients' preferences with respect to different methods of receiving test results while they were hospitalized and to determine whether the different modes of communication of the test results were associated with better recall. METHODS Five discrete test results were shared with adult inpatients on general medicine service (blood pressure, white blood cell count, hematocr...

Initial retrieval of an event can reduce people's susceptibility to misinformation. We explored whether protective effects of initial testing could be obtained on final free recall and source-monitoring tests. After studying six household scenes (e.g., a bathroom), participants attempted to recall items from the scenes zero, one, or two times. Immediately or after a 48-hour delay, non-presented...

It was hypothesized that subjective memory complaints represent the earliest sign of dementia in carriers of the presenilin-1 (PS1) mutation. A total of 122 subjects (44 males, 78 females) were included in this study. Forty of them were positive for the mutation in the PS1 gene (mutation positive, MP) whereas 82 showed negative results (mutation negative, MN). Subjects were active, functionally...

background and objective: identifying the details of the injurious effects of alcohol seems to be decisive in nowadays with growing abuse of the substance. this study mainly aimed to assess the adverse effects of ethanol on the recalling of information in the wistar rats. materials and methods: male wistar rats (pasteur institute of iran) were evaluated using the novelty seeking behavior based ...

A one-, two-, and three-pair dichotic digit test was administered to 180 subjects (20-79 years) with varying degrees of hearing sensitivity. The test was carried out under free- and directed-recall response conditions. The results indicated that recognition performance decreased as a function of increasing age. Statistical analysis using analysis of covariance indicated that differences in perf...

250 words) Although a group of people working together remembers more than any one individual, they recall less than their predicted potential. This finding is known as collaborative inhibition, and is generally thought to arise due to retrieval disruption. However, there is growing evidence that is inconsistent with the retrieval disruption account, suggesting that additional mechanisms also c...

OBJECTIVE To investigate the influence of memory training on initial recall and learning. METHOD The Advanced Cognitive Training for Independent and Vital Elderly study of community-dwelling adults older than age 65 (n = 1,401). We decomposed trial-level recall in the Auditory Verbal Learning Test (AVLT) and Hopkins Verbal Learning Test (HVLT) into initial recall and learning across trials us...

Three experiments, using a 2 (study context) x 2 (test context) between-subjects design, were conducted to examine the effects of environmental context manipulated by the combination of two contextual elements, place and task, on free recall. Undergraduates individually studied nouns and received a free-recall test, with a 10-minute filled retention interval. The contexts were manipulated by th...

Unconscious plagiarism (UP) occurs when an individual claims a previously experienced idea as their own. Previous studies have explored the cognitive precursors of such errors by manipulating the ways that ideas are thought about between initial idea exposure and later test. While imagining other's ideas does not increase rates of UP relative to control on either a recall-own or generate-new ta...
