The rationale behind Galton's theory or idea regarding heredity
were:
1. According to Galton, intelligence is inherited and that people
should be able to see patterns of higher intelligence which have
been passed down throughout families. The differences between each
person should be measured and classified.
2. Galton figured that in order to produce smarter offspring, the
reproduction must happen between more intelligent people and this
will discourage less intelligent people to mate, stating selective
breading was the best method, Galton’s pairing of intelligible
couples deemed a fit for society, in his mind.
Major issues regarding Galton's work are:
Galton was keenly interested in knowing whether human ability
was hereditary, and proposed to count the number of the relatives
of various degrees of eminent men. If the qualities were
hereditary, he reasoned, there should be more eminent men among the
relatives than among the general population.
Galton recognized the limitations of his methods, and hence studied
the comparisons of twins. His method envisaged testing to see if
twins who were similar at birth diverged in dissimilar
environments, and whether twins dissimilar at birth converged when
reared in similar environments.
Darwin believed in individual differences and had an influence on
psychology by proving that behavior, was just as important to study
as the mind was. By changing how we view human nature, there became
large influences on other areas such as developmental psychology
and animal psychology. Functionalism and behaviorism schools
started developing and making a stance in psychology. A
strength of Darwin’s theory is the survival of the
fittest. If one is equipped enough to thrive in its surroundings,
it will eventually become extinct. Animals must adapt to its
habitat and natural selection will occur over time through
mutation. A weakness in Darwin’s theory is that genetics
was never involved with evolution or natural selection. We cannot
just simply eliminate part of our genes which are hereditary in
order to adapt. Physically, natural selection is not part of a
human.
Structuralism and Act psychology are different in that Brentano
believed it was more important to understand what the mind actually
did instead of what it was made of. The mental process such as
judging, loving and hatred, are acts outside of itself.
Structuralism focuses on what the product of a humans mental
actions are. Psychology is more of an experience than an
experiment. A similarity between the two is that mental elements
must contain sensations, images, and affections.
Structuralism did not last for very long because Wundt and
Titchener’s philosophies were not including many new developments
such as abnormal behavior and basic elements of human
consciousness. After Titchener died, structuralism fell apart. In
order to have a positive effect on development, you needed to
incorporate a person’s personality and the differences in the human
mind. Structuralism’s failure also came from introspection, it was
very unreliable and was quickly thought of as retrospection.
