If it's not left, it's right: Electroencephalograph asymmetry and the development of emotion.

Fox, Nathan A.·1991·American Psychologist

Abstract

Recent studies suggest that an initial component involving stimulus evaluation may precede subsequent steps in the generation of emotion. This article presents a model for the development of emotion that involves an initial decision of approach or withdrawal, which results in motor programs, including facial expression, that facilitate either approach or withdrawal. With development, more complex emotions arise, as products of these basic initial responses and interaction with the environment. Evidence is presented that suggests that there are brain asymmetries (as measured by scalp recorded EEG activity) localized to the frontal region that are associated with the generation of emotion in infants. Variability in the pattern of EEG asymmetry between infants may be an important marker of differences in temperament.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Individuals with greater frontal alpha activity on the left relative to the right hemisphere display more reward-seeking behaviors than do individuals with greater activity on the right side.

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.
