Abstract

Although cognitive efforts were reported to elicit global autonomic arousal, which cognitive processes associate with autonomic arousal has not been clear. We investigated autonomic arousal across measuring pupil changes during the Stroop task. We compared cognitive conflict conditions (incongruent vs. congruent stimuli) and between erroneous and correct responses.Pupil changes were significantly greater at the beginning of each trial block. The variation of the pupil diameter were significantly greater with incongruent than congruent stimuli. Furthemore the pupil changes were greater when responses were incorrect. The results suggested that autonomic arousal occurs during cognitive conflict resolution. This findings are important because permitted to do a correlation between autonomic responses and cognitive processes.

Presentation

Hi

My name is Rocío, I´m Psychologist and I´m studing a Master in Neuroscience. My aim is understand how the nervous system, specifically the visual system, created a continuos experience, this line of research is called the binding problem and consists in two big questions 1) how brains segregate elements in complex patterns of data and 2) how the unity of conscious perception is brought about by the distributed activities of the central nervous system.

About this course, I hope to improve my english skills because I want to speak english fluent in any circunstance and with different people.

Thanks by read

See you
