These results on the similarity effect [45] serve as corroboration of several previous studies including [31] who found that monkeys make fixations to items that are similar in color but not orientation.
As a result, larger values of εxy represent a larger tendency to make fixations that are far away from their corresponding stimulus.
Once a fixation is made, fixation durations indicate how long higher-level focus is maintained on the same region, allowing for the extraction of greater visual details.
In contrast, the corresponding stochastic models have absorbing states, making fixation possible.
This shift did not correlate with prediction accuracy, making fixation differences an unlikely explanation of our findings.
The elimination of recombination across a genomic region will, in essence, lower the effective population size of that region, making fixation more likely for slightly deleterious mutations and less likely for slightly beneficial ones.
Increases in the fitness variance of asexual populations makes fixation of a beneficial mutant increasingly dependent on genetic background; only beneficial mutants that exceed a characteristic large size will have a high probability of fixing in populations with substantial fitness variance (Peck, 1994; Barton, 1995; Schiffels et al., 2011; Good et al., 2012).
In the worst-case scenario, participants might conduct the whole task by making fixations to random locations on the screen.
The metaphyseal location of the non-union after high tibial osteotomy can make stable fixation problematic because the proximal fragment is small and difficult to control with most conventional methods of internal fixation.
