Studies conducted to test individual differences in stress reactivity, such as the one conducted by S. Cohen and colleagues in 2002, suggested that is an important factor that influ­ences the stress-illness relationship.

Psychobiological reactivity to stress.

Explanation:

As the exercise details, what . Cohen and colleagues suggested was that psychobiological reactivity to stress is an important factor that influences the stress-illness relationship. We, as individuals, respond differently when exposed to the same stressor. Such differences can be observed in all four major stress response domains, namely, physiology, behavior, subjective experience, and cognitive function. So, to try this, S. Cohen must have tested different individuals with the same stressor to see how they responded, hence proving that the psychobiological reactivity to stress is an important factor.

yes, since there is a positive and a negetive if the positive and negitive wasn't there wouldn't a flow electricity in it.
