Originally developed in 1978 by Vandenberg and Kuse [5] based on the research by Shepard and Metzler (1971), [1] a Mental Rotation Test (MRT) consists of a participant comparing two 3D objects (or letters), often rotated in some axis, and states if they are the same image or if they are mirror images (enantiomorphs).

Arousal represents the vertical axis and valence represents the horizontal axis, while the center of the circle represents a neutral valence and a medium level of arousal. [11] In this model, emotional states can be represented at any level of valence and arousal, or at a neutral level of one or both of these factors.
There are also individual differences in the way the motion quartet is perceived: Some people require a different aspect ratio to perceive both axes of movement than others. A study using diffusion tensor imaging further showed differences in the structure of the corpus callosum, the primary connection between the two hemispheres, might be the ...
As with many areas of cognitive psychology, theories can focus on bottom-up or top-down aspects of the task. Bottom-up theories of representational momentum highlight the role of eye movements and stimulus presentation, [5] [6] while top-down theories highlight the role of the observer's experience and expectations regarding the presented event ...
The inability to perceive motion is called akinetopsia and it may be caused by a lesion to cortical area V5 in the extrastriate cortex. Neuropsychological studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans [1] is homologous to motion processing area V5/MT in primates.
The neuron most closely resembling the posture of the walking stimulus changes over time. The neural activation pattern can be graphed in a 2D plot, called a posture-time plot. Along the x axis, templates are sorted chronologically according to a forward walking pattern. Time progresses along the y axis with the beginning corresponding to the ...
Performing a movement leaves behind a bidirectional association between the motor pattern it has generated and the sensory effects that it produces. Such an association can then be used backward to retrieve a movement by anticipating its effects. These perception/action codes are also accessible during action observation.
Korte's four laws were first proposed in 1915 by Adolf Korte. [3] The third law, particularly, describes how the increase in distance between two stimuli narrows the range of interstimulus intervals (ISI), which produce the apparent motion. [4]
