The recently evolved mammalian species preservative behavior as opposed to the ancient self preservative behavior involves parental care, nursing, social interaction, pair bonding and mutual defense. Gonadal steroids together with oxytocin are critical for this affiliative, attachment behavior. When there is stressful loss of control, gonadotrophins are diminished, and the self preservative, fight-flight catecholamine coping response takes priority. It is suggested that self preservation is associated with left hemispheric brain function and that species preservation is associated with right hemispheric function. Stress during infancy that is severe enough to create insecure attachment has a dissociative effect, disrupting right hemispheric emotional functioning and species preservative behavior, and a permanent bias towards self preservation can become an adult trait. In such a person with impaired affiliation, corticoid responses may be deficient. The coronary type A behavior pattern common in our society exhibits some of this deficiency in species preservative activity.
与古老的自我保护行为相反，最近进化出的哺乳动物物种的保护行为包括亲代照料、哺乳、社交互动、配偶关系和共同防御。性腺类固醇与催产素共同作用，对这种亲和、依恋行为至关重要。当出现压力导致失控时，促性腺激素会减少，自我保护的“战斗或逃跑”儿茶酚胺应对反应会占据主导。有人认为，自我保护与左脑半球功能相关，而物种保护与右脑半球功能相关。婴儿期严重到足以造成不安全依恋的压力会产生解离效应，破坏右脑半球的情感功能和物种保护行为，而对自我保护的永久性偏向可能会成为一种成年特征。在这种亲和能力受损的人身上，皮质激素反应可能不足。我们社会中常见的A型冠心病行为模式在物种保护活动方面表现出一些这种不足。
