negative feedback (M = 11.72, SD = 33.01). When writing for a non-specified reviewer,
participants decreased the time viewing the prompt after positive feedback (M = -4.27,
SD = 19.81) and after negative feedback (M = -2.65, SD = 16.55); the amount decreased,
however, was not significantly different, F(1, 64) = .122, p = .72, ηp2 = .002.
There was also a significant interaction between audience and feedback on the
total number of typed keystrokes, F(2, 187) = 3.631, p = .028, ηp2= .37; see Figure 3.In
absolute terms, participants decreased their number of keystrokes in the professor and
peer conditions after receiving either positive or negative feedback, as well as in the non-
specified reviewer condition if positive feedback had been given. Simple main effect tests
showed that the change in number of keystrokes was marginally significantly different
after positive feedback (M = -41.1, SD = 761.15) compared to negative feedback (M = -
483.18, SD = 1021.5) only in thepeer condition, F(1, 64) = 3.815, p = .055, ηp2= .058.
The number of keystrokes also decreased in the professor condition following positive
feedback (M = -403.64, SD = 854.72) and negative feedback (M = -192.12, SD = 728.53),
although the differences was not significant,F(1, 65) = 1.15, p = .28, ηp2= .079.When
writing for a non-specified reviewer, there was no significant difference in the change in
number of keystrokes following positive feedback (M = -299.32, SD = 775.71) compared
to negative feedback (M = 20.03, SD = 698.71), F(1, 64) = 1.806, p = .184, ηp2= .028.
There was a significant interaction between audience and feedback on the total
number of submitted characters, F(2, 187) = 6.362, p = .002, ηp2 = .64; see Figure 4
