Causal Inference for Spatial Constancy across Saccades

Our ability to interact with the environment hinges on creating a stable visual world despite the continuous changes in retinal input. To achieve visual stability, the brain must distinguish the retinal image shifts caused by eye movements and shifts due to movements of the visual scene. This process appears not to be flawless: during saccades, we often fail to detect whether visual objects rem...

Color constancy: phenomenal or projective?

Naive observers viewed a sequence of colored Mondrian patterns, simulated on a color monitor. Each pattern was presented twice in succession, first under one daylight illuminant with a correlated color temperature of either 16,000 or 4000 K and then under the other, to test for color constancy. The observers compared the central square of the pattern across illuminants, either rating it for sam...

Visual Constancy during Movement. 2. Size Constancy Using One or Both Eyes or Proprioceptive Information.

A method for estimating constancy during motion, described in a previous paper, is used to find the effect of proprioceptive information of O's movement on visual size constancy. Os were carried in darkness backward and forward on a swing, while their constancy was estimated. It was found that constancy was improved when Os received proprioceptive information of their movement. Constancy was gr...

Into the winter whiteness.

A father recounts a transformative journey of love, loss, and learning as his son developed and eventually died of a fungal infection that occurred during a period of immunocompromise after a bone marrow transplantation to treat hypodiploid leukemia. He then thanks the many physicians, researchers, family members, and friends who came together to memorialize his son and create knowledge, hope, ...
