Is accommodation a confounder in pupillometry research?

چکیده

Much psychological research uses pupil diameter measurements to investigate the cognitive and emotional effects of visual stimuli. A potential problem is that accommodating at a nearby point causes constrict. This study examined what extent accommodation confounder in pupillometry research. Participants solved multiplication problems different distances (Experiment 1) looked line drawings with monocular depth cues 2) while their diameter, refraction, vergence angle were recorded using photorefractor. Experiment 1 showed pupils dilated performing multiplications, for all presentation distances. Pupillary constriction due was not strong enough override dilation load. 2 caused small shift refraction expected direction. We conclude that, young student sample we used, are substantially affected by accommodation.

Binary Confounders as Mathematical Objects: Confounder Influence and Confounder Intervals

Confounding is present in most observational studies. Yet by its nature, confounding is not generally present in the data. In order to use statistical associations as evidence for causal connections, one must try to take into account the influence of confounding. This paper reviews the role of confounding in the epic debate between Cornfield and Fisher on the statistical association between smo...

What Is the Best Research Globally?

Dr. Afshari’s editorial gives insight on human nature (1). Collaborative willingness usually occurs when different sides perceive personal benefit, or when institutions mandate collaboration. This is not unique between higher and lower income countries; many working in global emergency medicine (EM) observe this within wealthier countries. It exists among collaborators in low resource settings....
