Behaviour through the Imperative to Survive

While other theories on human behavior can explain some types of behaviours better than evolutionary psychology, this branch of study has credibility through understanding that the adaptive traits that are exhibited in human beings are part of a process that can explain all aspects of behavior from a historic, and prehistoric perspective of viewing the natural adaptive development of the human species.
In order to examine the effectiveness of evolutionary psychology in explaining human behavior, universal conditions can be examined for the common responses that are seen within the species. Using evolutionary psychology as a way of understanding attraction behaviors, for instance, reveals that men and women find each other attractive based on attributes that promote the survival of the species. Women will find men with resources more attractive, while men will find a physical attraction, which is associated with good health and childbearing potential, a more important attribute in potential mates (Keil &amp. Wilson, 2001, p. 751). Part of understanding evolutionary psychology requires an understanding that the behaviors that are present within the human species are directed towards specific adaptive purposes. Vuchinich and Heather (2003) argue that addictive behaviors are the result of an evolved psychological mechanism that has been shifted in the process of drug dependence (p. 251). This type of exaptation allows the researcher to examine the underlying cause of the responses that an addict will have to addiction to seeking stimuli.
Finally, looking at the example of aggression allows for the exploration of a set of behaviors that are typically tied to responses that are more blatantly tied to evoked responses. The frustration-aggression hypothesis postulated by Dollard suggests that when faced with a frustrating stimulus that would instigate the behavior of aggression, a shift will occur in the target of that frustration if that target is socially out of reach in regard to an aggressive response, thus creating a scapegoat that will feel the response that was delayed and/or shifted (Hogg &amp. Vaughan, 2005, p. 380).&nbsp.
