Research Methods (Ch 1, 5) Flashcards
Biopsychology
the study of the biology of behavior
1 million BC (view of Biopsych)
there has been damage to skulls found (people knew that the brain is an important part of keeping you alive)
7000 BC (View of Biopsych)
there are specifically drilled holes found in skulls (trepanation). They were meant to be a survivable surgery to treat conditions (we assume).
3000 BC Ancient Egypt (View on Biopsych)
Ancient Egyptians understood that the brain was connected to behavior, however, they believed that the heart was where the soul and intelligence was from.
400 BC: Hippocrates (View on Psych)
The person to first theorize that the brain is the center of intelligence (very controversial)
200 AD: Galen (View on Psych)
- theorized that the brain is the center of intelligence
- different part of the brain = different behaviors
ex: (squishy part=feelings, hard part= movement, NOT ACCURATE)
1600 AD: Renaissance (View on Biopsych)
when they figured out that there are four lobes to the brain (Frontal, Parietal, Temporal, Occipital)
1859 AD: Darwin (View on BCS)
book: Origin of Species (Evolution)
1949 AD: Hebb (View on Biopsych)
book: The Organization of Behavior (behaviors are evolutionary, certain parts of the brain=certain behavior)
Jimmie G
Case Study: The Man Frozen in Time
- he had very short term memories after his time in the navy.
- he thought he was 19
- they figured out the cause with many approaches*
- it was/could be alcohol and not eating-
The Man who Made Faces Disappear
Case Study: Lashley
- when he looked a little away from the person and the head disappeared and he could see what was behind it.
- probably brain damage to the vision part of the brain
Neuroanatomy
study of the structure of the brain
Neurophysiology
study of the function of the parts of the brain
Neurochemistry
study of how chemical bases in the brain effect behavior
Neuroendocrinology
The study of how hormones effect behavior
Neuropathology
The study of disorders regarding behaviors and the brain
Neuropharmacology
The study of how drugs effect behavior/the brain
Pros of using Human subjects
- have human brains
- follow instructions
- can report experiences
- humans are cheap (no cages, food, etc)
Cons of using Human Subjects
humans are random (genetics, personality, etc)
only macro-level (people don’t let you cut open their brains)
Pros of non-human subjects
controllable
micro-level (you can open up their brains)
simpler structure (easier to understand and to cut open)
Cons of non-human subjects
non-human brains (we want to learn about human brains)
can we apply knowledge from this to humans?
expensive (cages, food, etc)
Experiment
requires the controlled manipulation of variables
independent variable
the variable that you control (change) for the experiment
dependent variable
the variable that changes bc of the change in the independent variable (the one you measure in the experiment)
