Section 4.1.2 Analysis for Experiment 7
The influence of emotion and scene component on the responses given
to same, similar and new items was analysed by conducting separate ANOVAs
on each of the different types of items for each experiment. The results from
the three 3 (emotion) x 2 (scene component) x 3 (response type) repeated
measures ANOVAs are reported below in Tables 4.1.3 and 4.1.4.
In summary, the emotional influence on recognition of specific visual
details was shown by a greater number of ‘same’ responses to same items for
emotional than neutral objects. The central-peripheral trade-off was indicated
by less ‘same’ responses to backgrounds that had initially been presented with
negative than positive objects, although this finding was only approaching
statistical significance. There was no overall emotional influence on responses
to new items, although planned contrasts revealed that participants were more
likely to give a correct ‘new’ response to new positive than negative items, and
correspondingly more likely to give a ‘similar’ response to new negative than
positive items. This was the only experiment in which any influence of
emotion was found on the responses given to new items and therefore it seems
likely that this is an anomaly in the data as we have no explanation for why
there would be a difference in responding to new items in this experiment only.
