Data were extracted and analysed in exactly the same way as for
experiment 7 (see table 5.2). Repeated measures ANOVAs were used to
examine whether the emotion of the object in the scene (negative, neutral,
positive) and scene component (object, background) interacted with the
different eye movement measures. The following ANOVAs were also
conducted with the additional factor of object location (central or not central).
Object location always interacted with scene component but as this factor did
not interact with emotion these results are not discussed further. Additionally
for average fixation duration there was a main effect of object location.
Repeated measures ANOVA analysing the number of fixations for the
factors emotion and scene component found no significant main effect for
emotion [F(2,34) = 0.49 , MSe = 0.02, p = .62, partial eta 2 = .03], but did find a
significant main effect for scene component (F(1,17) = 533.33, MSe = 480.28, p
< .001, partial eta 2 = .97), with a significantly greater number of fixations on
the object than the background. There was a significant interaction between
emotion and scene component (F(2,34) = 7.16, MSe = 3.02, p < .01, partial eta 2
= .30). Planned contrasts revealed a significantly greater number of fixations
were made on emotional than neutral objects (F(1,17) = 10.19, p < .01), there
was a greater number of fixations on negative than positive objects which
approached statistical significance [F(1,17) = 4.26, p = .06]. There was a
significantly greater number of fixations on backgrounds with neutral than
emotional objects (F(1,17) = 7.67, p < .05), and a significantly greater number of
fixations on backgrounds with a positive than negative object (F(1,17) = 4.77, p
< .05).
