Materials
The same materials were used as in experiment 7. An additional symbol
was shown to participants before each picture to provide warning of the
emotion contained within that stimulus. A sad / neutral / smiley face symbol
(! " #) was used to indicate that the object in the next picture would be
negative, neutral or positive. These symbols were from the Wingdings font and
were displayed at font size 25 in the centre of the screen instead of the fixation
cross.
Procedure
Study
All aspects of the experiment were identical to those of experiment 7,
apart from the warning that participants were given of the emotion of the object
that would appear in the next scene. The warning took the format of a small
symbol which replaced the fixation cross that appeared before the scene.
Participants were told in the instructions that before each picture they would be
shown a symbol which would indicate whether the next picture would be
pleasant, neither pleasant nor unpleasant or unpleasant. They were shown
which symbol indicated an unpleasant, neither pleasant nor unpleasant or
pleasant picture before they began the experiment. (For results of study phase
ratings see meta-analysis in Section 5.2, Chapter 5).
Test
This was conducted in exactly the same way as for experiment 7.
