  • There is an inverted U-shape relationship between task load and performance.

    “There is an inverted U-shape relationship between task load and performance as proposed by Yerkes and Dodson (1908).”
  • With task loads increasing from easy to complex, an individual's performance will increase up to a certain point after which performance starts to decrease at the point of overloading.

    “With task loads increasing from easy to complex, an individual's performance will increase up to a certain point after which performance starts to decrease at the point of overloading.”
  • The Yerkes-Dodson law describes an inverted-U relationship between arousal (stress) and task performance, with optimal performance at intermediate levels.

    “The Yerkes-Dodson law [Yerkes and Dodson, 1908, Diamond et al., 2007] describes an inverted-U relationship between arousal (stress) and task performance: too little arousal leads to disengagement, too much leads to anxiety and performance collapse, and optimal performance occurs at intermediate levels.”
  • Differing levels of arousal or stress may result in contrasting effects on memory, with some research suggesting an inverted U relationship as posited by the Yerkes-Dodson law.

    “Importantly, di ff ering levels of arousal or stress may result in contrasting e ff ects on memory, with some research suggesting an inverted U relationship as posited by the Yerkes-Dodson law (Yerkes & Dodson, 1908; e.g., Andreano & Cahill, 2006; Gagnon & Wagner, 2016; McCullough et al., 2015; Metcalfe et al., 2019).”
  • Yerkes and Dodson showed that in a simple visual discrimination task, rate of learning improved linearly with increased shock intensity, and in a more difficult task, an intermediate shock intensity produced more efficient learning than the highest intensity.

    “These investigators showed that when mice were trained in a simple, that is, black/white, visual discrimination task to avoid shock, their rate of learning improved linearly with an increase in the intensity of the shock. When mice were trained in a more difficult, that is, black/gray, visual discrimination task, their rate of learning was more efficient with an intermediate intensity of shock”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
