Non-veridical size perception of expanding and contracting objects

Observers were presented with various types of stimulus expansion and contraction which resulted in marked misperceptions of size. Firstly, the perceived size of an object which is changing in size is shown to be biased in the direction of the size change. Secondly, expansion or contraction of the internal texture of objects is found to influence their perceived size. Finally, an illusory textu...

Visually tracking and localizing expanding and contracting objects.

The maintenance of attention on moving objects is required for cognition to reliably engage with the visual world. Theories of object tracking need to explain on which patterns of visual stimulation one can easily maintain attention and on which patterns one cannot. A previous study has shown that it is easier to track rigid objects than objects that expand and contract along their direction of...

Is artists' perception more veridical?

Figurative artists spend years practicing their skills, analyzing objects, and scenes in order to reproduce them accurately. In their drawings, they must depict distant objects as smaller and shadowed surfaces as darker, just as they are at the level of the retinal image. However, this retinal representation is not what we consciously see. Instead, the visual system corrects for distance, chang...

Non-veridical visual motion perception immediately after saccades

It is widely assumed that combining the eye movement vector with the motion vector of the retinal image is both sufficient and necessary for recovering the direction and speed of visual motion. Here, we report that execution of a saccadic (rapid) eye movement in the dark systematically biased subsequent perceptual judgment of the direction of visual motion in the direction opposite to the sacca...

Expanding knowledge of contracting muscle.

Muscle chapters in physiology textbooks tend to be short and narrowly focused; muscle has been portrayed as both genetically fixed and seemingly singular in function to produce work while shortening. However, the suite of muscle functions is extremely broad, including noise maker, thermogenic organ, isometric ‘lock’ and a power source for projectiles, in addition to driving locomotion. Likewise...
