Processing Accuracy

Processing accuracy refers to the ability to not make errors during information processing and testing. Attempts to increase processing speed and reaction time should make note of processing accuracy to maximize efficiency.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect processing accuracy
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
grade-c Minor - See study
The increased processing accuracy appears to be secondary to reducing exercise-related fatigue, and occurs when testing is after exercise.
grade-c Minor - See study
An improvement in processing accuracy (assessed by amount of errors in a cognitive test) has been noted with fish oil in otherwise healthy adults that do not frequently consume fish products
grade-c Minor Very High See 2 studies
The number of errors seen in serial threes and serial sevens tasks appears to be reduced with acute supplementation of EGb-761
grade-c Minor - See study
There is a possible improvement in processing accuracy with supplementation of modafinil.
grade-c Minor - See study
Increased processing accuracy has been noted in otherwise healthy persons at 400mg PS daily when testing was conducted in a fatigued state (post exercise)
grade-c Minor - See study
Increases in processing accuracy are likely secondary to reductions in fatigue
grade-c - - See study
No significant influence on processing accuracy is seen with centella asiatica supplementation
grade-c - - See study
No significant improvements in the accuracy of cognitive processing appears to occur with supplementation of nigella sativa seeds.
grade-c - - See study
grade-d - Very High See 2 studies
One study in people with bipolar disorder failed to find an effect and so did one study in healthy people, despite an increase in processing speed.
grade-d - - See study
Processing accuracy does not appear to be significantly influenced with acute inhalation of peppermint extract during cognitive testing
