The ganzfeld effect was originally introduced into experimental psychology due to the experiments of the German psychologist Wolfgang Metzger (1899–1979) who demonstrated that subjects who were presented with a homogeneous visual field would experience perceptual distortions that could rise to the level of hallucinations.

Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially weapon munitions such as bullets, unguided bombs, rockets and the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
Throwing mechanisms, along with projectiles themselves, rank amongst the oldest technological artefacts in the archaeological records. They vary greatly in size and complexity, from the hand-held and extremely simple sling, to the very heavy and complex catapults. These two types of devices have in common with hand-throwing the fact that the ...
The oddball paradigm is an experimental design used within psychology research. The oddball paradigm relies on the brain's sensitivity to rare deviant stimuli presented pseudo-randomly in a series of repeated standard stimuli.
Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments.
[52] [53] Human cannonball circus acts use a catapult launch mechanism, rather than gunpowder, and are risky ventures for the human cannonballs. [54] Early launched roller coasters used a catapult system powered by a diesel engine or a dropped weight to acquire their momentum, [55] such as Shuttle Loop installations between 1977 and 1978.
Fixed action patterns are said to be produced by the innate releasing mechanism, a "hard-wired" neural network, in response to a sign/key stimulus or releaser. [1] [2] Once released, a fixed action pattern runs to completion. [1] This term is often associated with Konrad Lorenz, who is the founder of the concept. [1]
A defence mechanism can become pathological when its persistent use leads to maladaptive behaviour such that the physical or mental health of the individual is adversely affected. Among the purposes of ego defence mechanisms is to protect the mind/self/ego from anxiety or to provide a refuge from a situation with which one cannot currently cope ...
