Estimations of object frequency are frequently overestimated

Estimations of object frequency are frequently overestimated.

Real-world scenes are complex but lawful: blenders are more likely to be found in kitchens than beaches, and elephants are not generally found inside homes. Research over the past 40years has demonstrated that contextual associations influence object recognition, change eye movement distributions, and modulate brain activity. However, the majority of these studies choose object-scene pairs from...

The Size of Thought: Estimations of Object Size Are Relative to the Body

Studies have shown that visual perception is pliable and that perceptual estimations can be affected by factors such as an individual’s current eye height. It has been shown that perception of slope, distance, and height are subject to the influence of physiological and social variables. The studies conducted and outlined here investigated the impact of an individual’s height on estimations of ...

Surface Groups are Frequently Faithful

We show the set of faithful representations of a closed orientable hyperbolic surface group is dense in both irreducible components of the PSL2(K) representation variety, where K = C or R, answering a question of W. Goldman. We also prove the existence of faithful representations into PU(2, 1) with certain nonintegral Toledo invariants.

Negative Frequency-Dependent Selection Is Frequently Confounding

Persistent genetic variation within populations presents an evolutionary problem, as natural selection and genetic drift tend to erode genetic diversity. Models of balancing selection were developed to account for the maintenance of genetic variation observed in natural populations. Negative frequency-dependent selection is a powerful type of balancing selection that maintains many natural poly...
