Does the visual field move as you move your eyeballs, or does it only move when you move your head?
1dJust a bit confused about how visual field is defined. Based on its definition, does one's visual field move as they look around (but keep their head still)? Or does it only move when they move their head? Seems very important in, for example, split brain studies where we present different things to each visual field. submitted by /u/optimal_honeybee [link] [comments]
Would it be too easy to validate visual stimuli like this?
1dHello, For my research, I have to validate some visual stimuli. I am asking about the methodology part. So, I collected some pictures. I will ask as many participants as to vote their valence, arousal and so on like in other studies. Then, I will keep the most negative-positive voted images. I will use a threshold or something like if 95% of the sample voted negative, then it is negative. Is it e
