Global biogeochemical cycles are critical to life, most notably those of water, oxygen, carbon, nitrogen and phosphorus. 1  The nitrogen cycle is the transformation of nitrogen and nitrogen-containing compounds in nature. 2  The water cycle, is the continuous movement of water on, above, and below the surface of the Earth.
Blunted affect refers to a reduction in the intensity of an individual's emotional response. The emotional response of an individual with blunted affect is a lot weaker than one would expect in similar circumstances.
The intensity of the affect may be described as normal, blunted affect, exaggerated, flat, heightened or overly dramatic. A flat or blunted affect is associated with schizophrenia, depression or post-traumatic stress disorder; heightened affect might suggest mania, and an overly dramatic or exaggerated affect might suggest certain personality disorders.
