PSYCHOLOGY 101: Understanding Biological Psychology
There are three theoretical perspectives in psychology that attempt to explain human behavior.
The three perspectives are: Evolutionary Psychology, Behavioral Genetics, and Behavioral Neuroscience.
These perspectives have been researched extensively in an effort to explain the complex sum of behavior
and the mind drives human beings act the way they do. The three perspectives of psychology
all have valid theories based on research, I believe all three directly influence human behavior in a
Evolutionary psychology is a perspective that processes human nature as a grouping of evolved
psychological adaptations to consistently resurfacing problems in the environments of our ancestors. The
bottom line is we are shaped by the our ancestors who in turn were shaped by the environment they lived
in. Our ancestors passed on a mind that evolved with adaptive behavior that was geared to solve
problems in order to survive. Human beings possess natural selection which is defined as something that
will improve an organism’s chance of survival. Natural selection is behavioral and physical adaptations
we used to live in a specific environment. Human beings have had several options when presented with problems with the current
living conditions: first, move to a different location; second, change the environment some way and third,
go extinct. Since we are still in existence and thriving today is a testament to our ability to use our minds
and behavior to overcome problems. Adaptations are not conscious decisions that we deliberately make,
it is something that is built physically and behaviorally without knowledge to survive. If we were to live
in a village near a river and we need water; we would go to the river and retrieve it. If the river were to
run out of water, our natural instinct would be to go find another water source or move to another area.
Throughout mankind’s existence, there are several areas that have evolved from evolution; where we do
not required any training on: assisting others, sexual relationships, bearing children and attraction.
The second theoretical perspective Behavioral Neuroscience, looks at how neural activity of the
brain influences and produces behavior. Furthermore, it attempts to explain how nerves, sensory
and neurological impulses can produce normal and abnormal behavior. Behavioral Neuroscience has
two areas of focus: Sensation and Perception. Sensation deals with: vision, hearing, smell, taste and
touch. Sensations are reflexes that stimulate and drive behavior. The sensation areas differ between each
person and are influenced by personal experiences and cultural backgrounds. Our brains use vision to
identify the shape, size and distance of objects. Smell has been used to mark territories, signal for
danger, attract mates and set dominance in relationships. ...
