Neural correlates of power-related postures and their behavioural consequences: a preliminary electrophysiological investigation
Bibliographic record
Abstract
Social dominance is conveyed by expansive and contractive body postures, which also have feedback effects on individuals' own mood and behaviour. These feedback effects are the subject of the 'power posing' paradigm, which has grown in popularity in psychology; however, the neural mechanisms of feedback from expansive and contractive postures have never been investigated. We report here for the first time an exploratory neuroimaging study using electroencephalography during a 'power posing' design to investigate the neural correlates of this effect. We find that right-lateralized frontal asymmetry in neural activity was increased as a result of taking an expansive posture and that this asymmetry was correlated with the effects the posture exerted on participants' mood. We interpret this finding in the context of recent theories of frontal alpha asymmetry and motivational conflict.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
