Final answer:
Seligman's third element of explanatory style is personalization, which is linked to the likelihood of depression; individuals making internal, stable, and global attributions for negative events tend to be more susceptible to depression.
Step-by-step explanation:
Seligman identified three primary elements of an individual's explanatory style: stability, globality, and personalization. This concept is often related to one's likelihood of experiencing depression according to the reformulated theory of learned helplessness. Personalization refers to whether a person believes they have control or influence over the events, which aligns with the concept of the locus of control being internal or external. The reformulated version suggests that individuals who make internal (personal attributes), stable (permanent), and global attributions for negative events are more prone to depression.
