Psilocybin impairs high-level but not low-level motion perception.
The hallucinogenic serotonin(1A&2A) agonist psilocybin is known for its ability to induce illusions of motion in otherwise stationary objects or textured surfaces. This study investigated the effect of psilocybin on local and global motion processing in nine human volunteers. Using a forced choice direction of motion discrimination task we show that psilocybin selectively impairs coherence sens...
متن کاملEditorial: High-Level Adaptation and Aftereffects
Adaptation, in sensory and perceptual science, refers to the action of a prolonged exposure of a receiver (at the cellular level a sensory receptor, at the organismic level an animal endowed with sensory organs) to an environmental stimulus. While adaptation of sensory receptors is strictly equivalent to the physiological phenomenon of a reduced electrical response by a receptor following its s...
متن کاملLow-level mediation of directionally specific motion aftereffects: Motion perception is not necessary
Previous psychophysical experiments with normal human observers have shown that adaptation to a moving dot stream causes directionally specific repulsion in the perceived angle of a subsequently viewed moving probe. In this study, we used a two-alternative forced choice task with roving pedestals to determine the conditions that are necessary and sufficient for producing directionally specific ...
متن کاملAre high-level aftereffects perceptual?
A HIGH-LEVEL AFTEREFFECT, AND TWO WAYS TO EXPLAIN IT Imagine an experiment in which you show someone pictures of a computer-generated face displaying random expressions, ranging from happy, through neutral, to sad. You tell the participant that she must classify each picture as being either “happy” or “sad,” and you note the point on the expression continuum at which she switches from mostly-“h...
متن کاملUsing low-level motion for high-level vision
The work presented within this Thesis describes a method to extract the 3D pose of a human performing a gaited action using only the motion of a sparse set of tracked features. The features used are not extracted using specific limb detectors, but are selected and tracked automatically using a standard feature tracker. These features contain noise that is not Gaussian in nature, but systematic,...
