Computerised within-meal VAS
VAS ratings made during the meal, were used to calculate mean
hunger, fullness and pleasantness ratings. These were analysed with
independent t-tests by condition (unaware vs. aware). For pasta, rated
fullness was significantly lower in the aware condition compared
to the unaware condition (55 mm vs. 63 mm; t (37) = 2.12, p < 0.05;
see Fig. 1), and there was a trend for greater hunger in the aware
versus unaware condition (42 mm vs. 35 mm; t (37) = −1.78, p = 0.08).
Rated pleasantness did not significantly differ between conditions
(aware = 70 mm vs. unaware = 68 mm; t (37) = −0.50, p > 0.05). For
cookies, hunger was significantly higher in the aware group versus
unaware (18 mm vs. 9 mm; t (37) = −2.48, p < 0.05; Fig. 1). However,
neither rated fullness nor pleasantness of the cookies, differed by
condition (both p > 0.05).
