Emotional priming with IAPS pictures

Differences in processing pleasant, unpleasant and neutral emotional stimuli were detectd with different methods, but with no consistent results due to usage of different methodology, type of stimuli and participants. In this research we conducted a reaction time study with emotional pictures from IAPS. Pictures are divided in three categories ; valence, arousal and dominance. In order to detect differences in RT for pictures with different valence, an experiment with 180 emotional pictures divided into three categories by valence was conducted. We used emotional priming in presenting pictures, randomized within every valence category. Prime pictures were presented for 100 ms and target pictures for 1000 ms with 500 ms breaks in between. Participants needed to answer whether they found target pictures pleasant or not. Differences in RT between emotional pictures with different valence values in regard to priming pictures were analyzed.
