Thayer (1986, 1989), for example, has shown that self-report measures of how peppy, active or vigorous a person feels correlate well with a broad range of physiological measures of arousal, usually better than the intercorrelation of such measures with one another.

To establish construct validity of a test or measure, the researcher must determine the extent to which the measure correlates with other measures designed to measure the same thing and whether the measure behaves as expected.

Dr. White, of Boston University, suggested that measures of mercury in umbilical cord blood correlated better with neurological effects than measures in hair.

The measures [of distraction] did not correlate significantly with each other or with performance; they often did not produce significant differences between conditions; they occasionally failed to parallel and even reversed the trends from relevant performance data.

These attempts have failed because measures of authoritarianism always correlate at least slightly with the right.

Clearly the individual-level measure is tapping into different concepts as the two pairs are not even positively correlated.

There is evidence that, in normal adults, commonly used behavioral measures of inhibitory control correlate with standard self-report measures of impulsivity.

In addition, these aforementioned studies found that female participants scored higher on empathy self-report dispositional measures and that these measures positively correlated with the physiological response.

Research has found that specific physiological measures correlate with the experience of transcendental consciousness, including lower respiratory rates, greater heart rate variability, higher amplitude alpha brain waves, and greater alpha coherence.

Correlation between fMRI and VVIQ scores showed that, in both object-selective and early visual cortex, Lee et al.'s (2012) measure of discrimination across imagery and perception correlated with the vividness of imagery.
