Abstract text:	Effective photojournalism provokes an emotional reaction and leaves a lasting impression upon the viewer. Striking and memorable images are often said to possess “impact”. Within cognitive neuroscience memorable emotional images evoke a greater amygdala response. Research to date has focused on arousal as a causative factor, while the contribution of appraisal dimensions relating to an item’s salience, goal relevance, or impact are yet to be addressed. We explored how differences in ratings of impact influenced amygdala activity to negative emotional images matched for valence, arousal and other factors. Increased amygdala activation was found to high impact compared to neutral images, or high impact compared to low impact images (matched for arousal). Our findings demonstrate that the amygdala response to emotional stimuli is not a function of arousal (or valence) alone and accord more with the proposal that the amygdala responds to the significance or relevance of an event.

The Reprint Request service is currently unavailable. The webform interface is not passing on your requests despite saying it has. PDF's of articles are also not available unless specifically linked from the record under the link field. Open Access papers are accessible this way when available. We are not able to fulfill pdf requests due to copyright and contractual restrictions. Inclusion in the Bibliography does not mean that a copy is available, this is foremost a record of the unit's work. Papers marked 'In Press' have not been published so are not available. Books and tests are also not available for copying. These are commerical products and you will need to buy them, or indeed contact your local library service to get a copy. If a record is from a conference and does not show more than one page number then the record/abstract on the page is the complete record. These are mainly a record of participation in a conference, such as a poster or a talk. Some of these records represent literally nothing more than a line.
