【3】Biopsychology - Important Figures

Phineas Gage (1823-1860)

  • Had an accident as a railroad foreman when has was 25 on September 13, 1848 that caused a iron rod to lodge into his head while blasting it down a hole to clear out rocks.
  • Despite this, he was still able to stand, walk, and speak after this incident.
  • In the proceeding months, his behavior changed drastically, changing from a mild soft-spoken man to a violent and odd one that would behave inappropriately.
    • Lost impulse control, a frontal lobe function.
    • It is possible that more than just that part of the brain was impacted.

 Henry Molaison (1927-2008)


  • Had a brain surgery in 1953 to treat his case of severe seizures when he was 27.

  • However, he could still learn new skills, even though he had no conscious memories of learning them.

Those with 2 of the SCA aren't immune to malaria. Carrier -  has one copy of a gene instead of 2; doesn't necessarily show symptoms of diseases resulting from the gene Genetic Variation  - genetic differences between individuals that contribute to a species' adaptation to its environment Phenotype  - physical characteristics with genetic & environmental factors Genotype -...

☆ Psychology is the scientific study of the mind and is based on measurable data. Scientific Method hypothesis - explanation that might explain a phenomenon. Hypotheses should always be broad explanations for some aspect of the natural world that can be consistently supported with evidence over time.      Ex) a bird sings when it's happy -> a bird sings to attract mates Results from the experiment of the hypothesis must be reproduceable  to be valid . -> published / presented to research conferences so others can replicate and build on the results. Theory - hypothesis that has been reproduced successfully multiple times; the best explanation available currently Science can't give knowledge about values and morals. It's limited because thoughts are neither matter nor energy which are quantifiable things. Structuralism         ---> Key Figures: Wilhelm Wundt, Edward Titchener Psychology became an academic discipline in the 1800s. Before i...
