The phrase "average fixation durations" is correct and usable in written English.
It can be used in contexts related to psychology, eye-tracking studies, or any research involving visual attention and reading behavior.
Example: "The study revealed that the average fixation durations varied significantly between different age groups."
Alternatives: "mean fixation times" or "typical fixation lengths".
A similar pattern is found for average fixation durations.
The average fixation durations are 321 ms (SD = 241) and 456 (SD = 406), respectively, for the top and bottom panel.
In general, the average fixation durations identified through our algorithm are similar to those in previous accounts summarized above.
Rayner et al. found average fixation durations of 254 ms during (English) reading, 210 ms during visual search, and 280 ms during scene viewing, amongst others.
The average fixation durations during reading varied from 150 220 ms, during visual search from 190 230 ms, and during scene viewing from 200 400 ms.
At the individual level, the MAD is 56.98 ms overall, and for reading even 71.15 ms. Similarly, the correlations between the computed average fixation durations based on our algorithm and the alternative are low, ranging from.28 for reading to only.20 for ad exploration.
In addition to the above effects, pedestrians distracted by phone conversation cross the street more slowly, direct fewer fixation points to the right traffic area, and spend less fixation time and lower average fixation duration on the left traffic area.
In the Context condition, the average fixation duration was slightly descriptively longer than the No-context condition (Table 1), but not significantly different (t (82) = 0.438, p = 0.662; intersaccadic interval 1° cleaning, t (82) = 0.888, p = 0.377).
In the Comprehension group the average fixation duration was descriptively longer (Table 1) than the Map task group, but not statistically significant (t (100) = 0.695, p = 0.489; intersaccadic cleaning, t (100) = 0.672, p = 0.503).
To describe the relationship, Tukey HSD post hoc comparisons for the analysis without intersaccadic interval cleaning indicated that the Context + Inference group had the shortest average fixation duration, which was significantly shorter (p = 0.026) than the No-context group (Table 1).
It also yields average fixation duration (ms), average 'smooth pursuit' duration (ms) and average saccade amplitude (size in degrees).
