Stage fright and enthusiasm, the same surge

Walter Cannon objected as early as 1927 to William James's theory that visceral reactions were too undifferentiated to distinguish one emotion from another. A century of measurement has partly proved him right: differences between states exist, but they are weak and inconstant.

It is precisely this limit that makes sensor-based detection devices fail. Skin conductance and heart rate inform well about the intensity of activation, badly about its nature.

Stanley Schachter and Jerome Singer proposed that an emotion results from the combination of a physiological activation and a label supplied by the context. Their protocol, based on an adrenaline injection and the presence of a euphoric or irritated confederate, is taught everywhere.

It should be known that its replications have been disappointing, and that several comparisons in the original study were not significant. The general principle, for its part, has been supported by other routes, notably by the suspension bridge experiment of 1974, where arousal due to fear is attributed to attraction.

The label is not simply a word placed after the fact. It orients what follows: depending on whether one reads one's surge as stage fright or as impatience, one prepares a defence or an action, one withdraws or engages, and the body then receives feedback consistent with that conduct.

This loop is not magical and authorises no promise. Work has explored the avenue of beliefs about stress, with interesting and fragile results, obtained on limited samples. They require confirmation before being taken as settled.

The label available depends mainly on what the situation offers. On a stage, the activation is called stage fright because the word circulates and those around supply it. At the start of a race, the same surge is called something else, and nobody worries about it.

The ambient vocabulary is therefore not neutral: it orients interpretation even before the person has time to examine what is happening. The same is true of questionnaires, whose items offer labels the respondent would not necessarily have chosen.

It does not follow that renaming one's fear would be enough to transform it. That kind of advice circulates a great deal, and it rests on a considerable extrapolation from small effects, measured in a laboratory, on brief situations.

What the literature establishes is more modest and already useful: one and the same activation does not by itself determine what will be experienced, and the interpretation adopted is not the only possible one. Noting this is not a method, it is a fact.
