Arousal is an elusive energy which is produced by the interaction of internal and external stimuli. This energy is a byproduct of the drive to satisfy both inner and outer motivations. The relationship between arousal and behavior impacts the human body in many ways.
This can be noticed as muscle tension, sweaty palms, and in some people these experiences are accompanied with increased heart rate and heavy breathing. Arousal can be experienced as a good feeling and can induce heighted feeling of the desire to be intimate.
Arousal also includes anxiety and fearful behaviors which allow for a diminished performance this idea also depends on the complexity of the task. Arousal can affect performance in a few ways. Arousal enhances performance up point and then as arousal becomes greater the person’s performance begins to suffer.
This is noted as an inverted-U relationship. High arousal has been proven to produce the greatest performance on easy tasks and the lower the arousal the better the person performs on any given task. Hull drive theory agrees with this response. The necessary performance required is dependent on the difficulty of the task.
