Some of the strengths of the various biological and evolutionary
perspectives of personality are:
- Bridges biology and psychology
- Explains individual differences which are not easily accounted for by
environmental explanations
- Twin and adoption study research
- Laboratory brain study research
- Animal study research
- Supported by evolutionary theory
- Recognize biological limitations on therapeutic efforts
- Pharmacological intervention
- Much potential for the future
Some of the weaknesses of the Biological Perspectives are
- Still limited methods for testing theories
- That the evolutionary perspective has political and social undertones
and may allow justifications for unfair social conditions and prejudices
(sexism)
- Limited strategies for change from evolutionary perspective and
genetic perspective.
- The study
of the biological perspective of personality IS fragmented. It is a
relatively new area in which knowledge is growing and changing all the
time.
- Evolutionary & biological often address particular aspects of
personality, but not the study of all aspects of personality as a
whole
The mapping of the human genome (i.e. the complete set of genes found in
mankind’s 23 pairs of chromosomes) is in many ways going to give us an
autobiography of our species. It remains to be seen whether people will
start to demand designer babies when we uncover more and more of the
biological secrets of our personalities!
