Heredity can influence behavior in many ways, with one such example being how color is processed in the brain; color blind people perceive the world in an alternative way, which can cause changes in how everyday tasks are approached. Color perception is directly linked to genes, which illustrates just one way heredity can affect human behavior.Know More
While heredity is certainly one factor that can dictate behavior, it is thought to be closely associated with the effects of environment as well.
Isolating exact behavior changes or patterns to genes is problematic due to the fact that it is highly unethical and immoral to conduct genetic experiments on humans in order to gain scientific evidence. That said, through the study of genetics and human biology there are alternative ways to observe genetic effects on behavior to some extent.
Genetic mutations in the retina provide the strongest evidence that genes influence behavior, and while it is logical to assume that the same could be said for other mutations, there is no credible evidence to suggest that other mutations have the same effect on human behavior.
Environment can have a profound affect on genes themselves, with genetic expression changing as a result of environmental conditions. As such, it is very difficult to identify whether genes or environment have precedence when analyzing the causes of behavior change.Learn more in Psychology
Normal behavior is behavior that is average and not out of the ordinary, while abnormal behavior is different from the majority of society, according to Psychology Today. There is a wide range of behaviors that are normal and behaviors that are abnormal.Full Answer >
According to Arianne Cohen and Lindsy Van Gelder of Real Simple, people who are lying exhibit certain characteristic changes in their behavior, such as altered voice inflections, disassociation with their self-narrative and excessive fidgeting.

In biology, a stimulus is a change in an organism's surroundings that causes the organism to change its behavior in order to make the environment more satisfactory. For instance, hunger motivates animals to seek food, predators stimulate prey to run away or hide, and falling temperatures encourage creatures to seek shelter or find warmth in other ways.Full Answer >
