There was a significant main effect of response type (F(1.41,32.38) = 30.30, MSE
= 2.28, p < .001, partial eta 2 = .57) and a significant interaction between
emotion and response type (F(2,46) = 8.06, MSE = 0.10, p < .001, partial eta 2 =
.26). This interaction was analysed further with post-hoc t-tests to compare the
responses given to negative and neutral items. Significantly more remember
responses were given to negative than neutral items (t (23) = 3.87, p < .001).
There was no significant difference in the know responses given to negative
and neutral items [t (23) = -1.68, p < .11]. Significantly less new responses
were given to negative than neutral items (t (23) = -2.50, p < .02). Orthogonal
contrasts revealed significantly more ‘remember’ than ‘know’ or ‘new’
responses were given (F(1,23)=36.04, p < .001), although there was no
significant difference between the number of ‘know’ or ‘new’ responses given
[F(1,23)=3.42, p = .08].
Next, a repeated measures ANOVA with the factors emotion (negative,
neutral) and response type (remember, know, new) was conducted with the
distractors, that is the items that were similar or new at test. There was a
significant main effect of response type (F(1.40,32.18) = 72.61, MSE = 4.23, p <
.001, partial eta 2 = .76) and a significant interaction between emotion and
response type (F(1.61,36.99) = 21.37, MSE = 0.11, p < .001, partial eta 2 = .48).
This interaction was analysed further with post-hoc t-tests to compare the
responses given to negative and neutral items. Significantly more remember
responses were given to negative than neutral items (t (23) = 7.15, p < .001)
and significantly less new responses were given to negative than neutral items
(t (23) = -5.52, p < .001). There was no significant difference in the know
responses given to negative and neutral items [t (23) = 0.89, p = .38].
