Therefore, we set out to increase the difficulty of the gap detection task by measuring the smallest possible gaps that subjects with and without tinnitus can detect.
These results highlight the difficulty of the gap parsimony approach to recover sufficient phylogenetic information, even when the correct guide-tree is used.
Our analyses on simulated sequences provide some insights into the difficulty of inserting gaps at correct positions, even when the correct guide-tree is used.
This result pattern is inconsistent with the hypothesis that dwell times are predominantly determined by the perceptual difficulty of detecting the gap.
By contrast, dwell times did not appear to be affected by line thickness per se, contrary to the view that dwell times are primarily determined by the perceptual difficulty of detecting the gap.
If dwell times are predominantly modulated by the perceptual difficulty of detecting a gap in stimuli of different line-widths, then we would expect dwell times on distractors with thin line-width to be consistently longer than dwell times on the medium or thick distractors, regardless of their similarity to the target.
We show that major methodological challenges in using routine data arise from the difficulty of understanding the gap between patient and their 'data shadow'.
Beinborn et al. (2014) worked on predicting the gap difficulty of the C-test3 using a combination of factors such as phonetic difficulty and text complexity, while Hoshino and Nakagawa (2010) and Susanti et al. (2016) investigated factors affecting item difficulty on multiple-choice vocabulary questions.
However, no item was unfit for the projected linkage, and there was no difficulty gap of 0.3 logits between the two measurement points.
Facing the difficulties of closing the gap between research and practice, the UCLA/RAND NIMH Center has developed a framework to assess the relevant contextual factors, identify, develop and evaluate new strategies, provide useful formative feedback, develop capacity among stakeholders and to meaningfully generalize findings.
