Sentence examples for visibility testing from inspiring English sources
We propose a five-point typology on the levels of theoretical visibility, testing this against a range of published research from five key international health, medicine and social science journals.
According to the image-source principle, all the obstacles that lie in the same half space of the image-source, are discarded during the visibility test.
Then the simple visibility test is performed to determine whether the cyber-information appears in current image or not: V ( x, y ) = 1, 0 ≤ x ≤ W, 0 ≤ y ≤ H 0, otherwise (2).
Specifically, on each trial of this visibility test, participants first saw a fixation cross (1,000 ms).
These 9 subjects were at chance when discriminating the direction of motion in the uncued diagonal during the visibility test (mean d' = −0.04, p =.81).
We obtained similar results when we excluded all subjects with positive d's or all subjects with performance better than 55% on the visibility test (both ps <.05).
This is consistent with the prime visibility tests and suggests that our masking procedures were effective for both pictures and words.
Similarly, we analyzed the data from the visibility test (i.e., the 100-trial procedure performed after the main task in which we explicitly tested for the visibility of the uncued motion patches).
In the main part of the experiment, the motion in the uncued diagonal was completely irrelevant to the task and subjects were instructed to ignore it, while in the visibility test, subjects were encouraged to pay attention to both diagonals.
For two of the subjects, 25% coherence was used, and a visibility test was performed at the end of the experiment to confirm that they could clearly see the motion in the cued diagonal.
