Differences Between Humans and Other Animals
There are several aspects of human helplessness that have no counterpart among animals. One of the most intriguing aspects is "vicarious learning (or modelling)": that people can learn to be helpless through observing another person encountering uncontrollable events.
Apart from the shared depression symptoms between human and other animals such as passivity, introjected hostility, weight loss, appetite loss, social and sexual deficits, some of the diagnostic symptoms of learned helplessness—including depressed mood, feelings of worthlessness, and suicidal ideation—can be found and observed in human beings but not necessarily in other animals. In non-human animal models, control over stress conveys resilience to future uncontrolled stressors and induces changes in the function of specific neurons within the prefrontal cortex.

Famous quotes containing the words humans and/or animals:
“Because humans are not alone in exhibiting such behavior—bees stockpile royal jelly, birds feather their nests, mice shred paper—it’s possible that a pregnant woman who scrubs her house from floor to ceiling [just before her baby is born] is responding to a biological imperative . . . . Of course there are those who believe that . . . the burst of energy that propels a pregnant woman to clean her house is a perfectly natural response to their mother’s impending visit.”
—Mary Arrigo (20th century)
“The moles nested in my cellar, nibbling every third potato, and making a snug bed even there of some hair left after plastering and of brown paper; for even the wildest animals love comfort and warmth as well as man, and they survive the winter only because they are so careful to secure them.”
—Henry David Thoreau (1817–1862)
