Table 1 Definitions of subphases of trials

From: Gaze behavior and cognitive states during fingerprint target group localization

Subphase Definition Example
A A period at the start of Comparison prior to the examiner first looking at the target area, in which all fixations in the right image are outside the target area. Because Subphase A was often very brief, we use “AL” and “AS” to indicate whether the subphase was longer or shorter than 1 s In Fig. 9, for trials in which the first right fixation is red (out of the target area), Subphase A is the period prior to the first continuous 0.5 s of blue (in)
B Any period of time not in Subphase A or C In Fig. 9, Subphase B is a period alternating between blue and red (after initial red and final blue periods)
C A period at the end of Comparison when the examiner is only looking at the target area, in which all fixations in the right image are in the target area in the right image In Fig. 9, for trials in which the last right fixation is blue (in the target area), Subphase C is the period after the last 0.5 s of red (out), until the end of the trial; for trials that have no red, the entire Comparison phase is considered Subphase C
