I'm reading the paper "Visual Space Perception and Visually Directed Action" by Loomis, Da Silva, Fujita and Fukusima (1992; pdf). In this paper, the word 'veridicality' is used in several sentences.
Even with such a narrowed focus, it is apparent that no consensus on the veridicality of visual space perception exists, for the experimental results depend strongly on both the criterion of veridicality and the psychophysical method used.
One criterion for veridicality is linearity of the function relating perceived egocentric distance to physical distance.
I used dictionaries and websites (including Wikipedia) to get a grasp of this concept, however, I found nothing that gave good meaning to this word. I assume this is a psychological term, since the linguistic meaning didn't fit well in my opinion.
What does 'veridicality' mean, and how I should interpret it in this context?
