Cognitive complexity is a psychological characteristic or psychological variable that indicates how complex or simple is the frame and perceptual skill of a person.t is used as part of one of the several variations of the viable non-empirical evaluation model GOMS (goals, operators, methods, and selection rules); in particular the GOMS/CCT methodology. Cognitive complexity can have various meanings:
Essential tremor is a nerve disorder in which tremors occur without an identifiable cause. The tremor resembles an exaggerated shaking and occurs when a person is using his or her hands but does not occur while the hands are at rest. Parkinsonâs tremors are just the opposite â noticeable shaking when at rest but no shaking when the hands are engaged.
There are a couple different reasons for tremor in the hands. First, if your are fatigued, sometimes this comes out in the muscles as a tremor. It can be worsened by caffeine, such as coffee or soda. Fatigue alone as a cause of muscle shaking would be unusual just in the mornings, however, as one would think that that is when you would be at your least fatigued. A second cause would be essential tremor. This is a relatively benign neurological condition of unknown cause in which a part of the body (usually the hands) shakes, primarily when trying to perform an action as opposed to when at rest. Essential tremor is also worsened by caffeine, like a fatigue tremor. There are several medications which can be used effectively to decrease the severity of essential tremor. Other causes of tremor would be unlikely in a young man, but still need to be ruled out by your doctor.
