Psychology Chapter 1 (Slide 7-11)
Slide 7: These were the ‘stage setter’ to psychology.
Some people had doubts though on studying a human- how do you study what’s inside? Depends on
how smartly you design an experiment. Ex: see how fast an action takes to be instructed by the brain by
timing the person doing the task.
Note: Our brain does not transfer information faster than a computer.
Ernst studied psychophysics: attempt of applying the study of physics by studying the ‘inside’- the mind.
Experiment: He got subjects to close their eyes and hold out their hand. He’d place weights of equal
weight on each hand and asked them which one was equal. He then started placing different weights
and noted how much of a difference was needed until they could notice. They ended up using relations
(this is heavier than this side) and fractions (ex. one hand is lighter by 1/10) to perceive differences,
instead of stating actual weight Weber’s fraction
The internal sensation, not the external reality, was studied in this experiment psychophysics. This
one was the first on to use this technique to study the mind and start off psychology
Note: many of the scientists originate from Germany (around late 1800s), because they were
economically powerful. The country invested in science and pushed researchers to move into their field.
Wundt was interested in conscious experience. Used introspection, but the problem was how he was
able to study the inside, like the thoughts and mind. What he did was he trained students on paying
attention and saying what they have in mind (ex. What they see in a colour and describe it). This focus
on their description became structuralism: the structure of an object (ex. What a bulldozer looked like
During that time, introspection was frowned upon because it’s hard to describe everything that is on the
mind. The conscious experience is edited, and you don’t describe everything.
Darwin started changing up biology from just picking up species and naming them to adding more in-
depth thought to biology (why does this animal look like this
