A file extension is the set of three or four characters at the end of a filename; in this case, .obj. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically.
A threshold (or limen) is the point of intensity at which the participant can just detect the presence of a stimulus (absolute threshold) or the presence of a difference between two stimuli (difference threshold). Stimuli with intensities below the threshold are considered not detectable (hence: sub-liminal). threshold (or limen) is the point of intensity at which the participant can just detect the presence of a stimulus (absolute threshold) or the presence of a difference between two stimuli (difference threshold). Stimuli with intensities below the threshold are considered not detectable (hence: sub-liminal).
Absolute threshold - The minimum amount of stimulation needed for a person to detect the stimulus 50 percent of the time. Accommodation - The process by which the shape of an eyeâs lens adjusts to focus light from objects nearby or far away. Also: the modification of a schema as new information is incorporated. Acetylcholine - A neurotransmitter involved in muscle movement, attention, arousal, memory, and emotion.
