This is probably a variant of The Hawthorne Effect, e.g.:

    In an early (1927-1933) productivity study in Western Electric's
    Hawthorne plant near Chicago researchers discovered that their own
    presence affected to outcome of the study. In this case, so long as
    the study was in progress productivity increased. The term "Hawthorne
    Effect" was thus coined to define the influence of the researcher's
    presence on the outcome of the study. Or, put another way, attention
    increases productivity. ...

In particular, it didn't matter whether the experimenters increased the
lighting or lowered the lighting (or later: humidity, temperature, frequency
and length of breaks) -- if they *changed* something, productivity increased.

Or more to the point, when the presentation ceases to be "experimental".
