The epigenetic clock leads to a chronological age prediction that has a Pearson correlation coefficient of r = 0.96 with chronological age (Figure 2 in [10]). Thus the age correlation is close to its maximum possible correlation value of 1.
The solid black line corresponds to y=x. Note that the Hannum predictor systematically under-estimates the ages of subjects who are younger than 20 (negative values of DNAm age on the y-axis). The Pearson correlation of the Weidener predictor (r=0.81, panel C) is lower than that of the other two predictors (e.g. r=0.98 panel A).
Mental age is a concept related to intelligence. It looks at how a specific individual, at a specific age, performs intellectually, compared to average intellectual performance for that individual's actual chronological age (i.e. time elapsed since birth). The intellectual performance is based on performance in tests and live assessments by a ...
The highest score obtainable by direct look-up from the standard scoring tables (based on norms from the 1930s) was IQ 171 at various chronological ages from three years six months (with a test raw score "mental age" of six years and two months) up to age six years and three months (with a test raw score "mental age" of ten years and three ...
An intelligence quotient ( IQ) is a total score derived from a set of standardised tests or subtests designed to assess human intelligence. [ 1] The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in ...
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy. [ 1][ 2] Absolute dating provides a numerical age or range, in contrast with relative dating ...
Biomarkers of aging are biomarkers that could predict functional capacity at some later age better than chronological age. [ 1] Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age. Validated biomarkers of aging would allow for testing interventions to extend lifespan ...
MeSH. D014888. The Wechsler Adult Intelligence Scale ( WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. [ 1] For children between the ages of 6 and 16, Wechsler Intelligence Scale for Children (WISC) is commonly used. The original WAIS (Form I) was published in February 1955 by David ...
