Contrast modulated maskers: test of a late nonlinearity hypothesis.
Vision Research, 1989 The contrast threshold for detecting a low frequency test grating in the presence of a contrast-modulated high frequency masker is heavily dependent upon the phase relations between the gratings: test stimuli in + or - cosine phase are much more detectable than those in + or -sine phase.

A test of the “;ceiling effect”; hypothesis of positive contrast [PDF]
Psychonomic Science, 1970 Seventy-two rats were given 0, 5, 10, or 15 small rewarded trials prior to being shifted to large reward for the remainder of 45 trials. Each of the groups which experienced an upward shift in reward magnitude rapidly approximated the performance of a consistently large rewarded control group, and in no case was a positive contrast effect observed. The

Divide and Contrast: Self-supervised Learning from Uncurated Data [PDF]
IEEE International Conference on Computer Vision, 2021 Self-supervised learning holds promise in leveraging large amounts of unlabeled data, however much of its progress has thus far been limited to highly curated pre-training data such as ImageNet. We explore the effects of contrastive learning from larger,

Frontiers in Psychology, 2021 Interleaved practice (i.e., exemplars from different categories are intermixed within blocks) has been shown to enhance induction performance compared to blocked practice (i.e., exemplars from the same category are presented sequentially).

Lightness contrast & assimilation: testing the hypotheses
Primenjena Psihologija, 2021 Lightness contrast alters lightness of a target decreasing its similarity with neighbouring surfaces (inducers), while lightness assimilation has an opposite effect, similarity is increased.

Numerically probing the universal operator growth hypothesis. [PDF]
Physical Review E, 2022 Recently, a hypothesis on the complexity growth of unitarily evolving operators was presented. This hypothesis states that in generic, nonintegrable many-body systems, the so-called Lanczos coefficients associated with an autocorrelation function grow ...

Natural variation in female reproductive hormones does not affect contrast sensitivity [PDF]
Royal Society Open Science, 2018 Evidence suggests that females experience adaptive shifts in facial preferences across the menstrual cycle. However, recent discussions and meta-analyses suggest that these findings are equivocal.
