Dear Editor

Journal of Vision



I am enclosing a herewith a manuscript entitled: " Pupillary response as physiological marker in the decision making". The authors of this study are Rocío Mayol and Pedro Maldonado. We believe that the research is of interest because shows that pupil dilation has relation with cognitive processes as decision making, this finding show that when a cognitive task is more difficult, the pupill diameter is smaller than when the task is easier, these results are interesting, because suggested that autonomic arousal, specifically the pupill response, may be necessary to resolve a conflict and take a decision. Moreover this is the first study that measure pupillary response in a task of decision making.

The results of this study are original and have not been submitted to other media for publication.

If the study is published in the Journal of Vision, we give you all the rights of reproduction and publication.



Sincerely yours
