Investigation of Students' Knowledge and Iris Interrelationship

摘要

The interdependence between the psychoemotional state, ideational activity, different emotional stimulus and pupil size variation are known since the ancient times: so, a pupil diameter increase in case of concentration or anxiety is a commonly-known fact. In latter days investigators have been conducting research using computerized measuring devices to observe and explain the interdependence between the psycho-emotional state and pupil size variation. Thus [1] have conducted the research on pupil size variation during the mental arithmetic tasks performed by human subjects: We first replicated an experiment performed by [1, 2] for mental arithmetic. In each trial, subjects listened to two spoken numbers between 5 and 19. Five seconds after the second number was spoken, subjects were prompted to type the numbers' product into an onscreen keypad using the mouse. The use of an on-screen keypad kept users' eyes on the screen, in order to maintain pupil visibility and to avoid pupillary light reflexes caused by looking away from the screen. We observed a similarly-shaped pupil response to that reported by [1, 2].
