Importantly, individuals can also differ not only in their current state, but in the magnitude or even direction of response to a given stimulus. [5] Such phenomena, often explained in terms of inverted-U response curves, place differential psychology at an important location in such endeavours as personalized medicine, in which diagnoses are customised for an individual's response profile.
Selective breeding and the domestication of animals is perhaps the earliest evidence that humans considered the idea that individual differences in behaviour could be due to natural causes. [1] Plato and Aristotle each speculated on the basis and mechanisms of inheritance of behavioural characteristics. [2]
The biological basis of personality is a collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an active field of research.
Specifically, comparative researchers encounter problems associated with individual differences, differences in motivation, differences in reinforcement, differences in sensory function, differences in motor capacities, and species-typical preparedness (i.e. some species have evolved to acquire some behaviors quicker than other behaviors).

Personality psychology is a branch of psychology that examines personality and its variation among individuals.It aims to show how people are individually different due to psychological forces. [1]
Estimates of heritability use statistical analyses to help to identify the causes of differences between individuals. Since heritability is concerned with variance, it is necessarily an account of the differences between individuals in a population.
Personality and Individual Differences is a peer-reviewed academic journal published 16 times per year by Elsevier. It was established in 1980 by Pergamon Press and is the official journal of the International Society for the Study of Individual Differences.
The book traces the origins of the idea of individual differences in general mental ability to 19th century researchers Herbert Spencer and Francis Galton. Charles Spearman is credited for inventing factor analysis in the early 20th century, which enabled statistical testing of the hypothesis that general mental ability is required in all mental efforts.
