Chapter 1 Flashcards
what is psychology
the study of the behaviour, mental processes and brain functions
how is psychology a hub science
psychology teaches you about people, it is needed everywhere
- the most influential sciences = hub sciences
what does behaviour mean
refers to any action that we can observe
- human behaviour, animal behaviour
what does introspection mean
a personal observation of your thoughts, feelings and behaviours
- does not follow well with the scientific method because it is difficult for others to confirm your thoughts, behaviours and feelings (introspects)
- we have now used innovations in mathematics to investigate brain activity and behaviour
give examples of introspections being misleading
- if you say you are hungry but nobody else can tell if your observations are accurate because it is based on your own internal and independent feelings
- Would listening in a lecture hall and seeing someone in front of you actively multitasking on a laptop distract you? people would think it wouldn’t but the results of a quiz showed those who noticed the laptop scored lower
what is the top 3 most common dreams
being chased
arriving too late
trying again and again
what is philosophy
the discipline that systematically examines basic concepts including the source of knowledge
what is natural sciences
sciences that study the physical and biological events that occur in nature
what are the 2 major roots of psychology
philosophy
natural sciences
explain how philosophy is one of psychology’s roots
they share an interest in answering similar questions about the nature of self, the origin of knowledge, etc
- considering biological and environmental factors
- they both want to determine the relationships between self-interest and community welfare
philosophers investigated issues about unconscious mind and abnormal behaviour before psychologists
how do natural sciences have a root in psychology
when philosophers ask questions about whether the mind is inborn or formed throughout life, it starts with Aristotle and ten “black slate” birth and characteristics that are influenced by both genetics and experience like intelligence
- they thought the mind was supernatural but once mind and physical aspects came together they realized they could study the brain
they slowly incorporated physiological and psychological concepts into their work by running experiments like what is the softest sound a human ear can hear
what did the ancient greek philosophers think that relates to psychology
observations can be accounted for by natural explanations, not supernatural ones
what did the British empiricists think that relates to psychology
knowledge is the result of experience
what did the ancient physicians think that relates to psychology
the brain is a source of the mind
what did the natural scientists of the 17th and 18th century think that relates to psychology
discoveries about sensation and movement showed that the mind was physical
what did Hermann von Helmholtz think that relates to psychology
studies of reaction time reinforced the idea that the mind is physical
- he asked his participants to push a button when they felt a touch, the thigh gave a faster response to touch rather than the toes because it is further away from the brain
who was the first experimental psychologist
Wilhelm wundt
what was Wilhelm Wundt’s first experiment
he was training to be a doctor and wanted to use methods used in physiology to test psychological processes such as attention and decision-making
- “Is it possible to time mental processes?”
- stimuli = ball dropping + reaction time
- little risk to their patients
he said that the reaction time is a measure of the amount of mental processing required to carry out a task - as more complex tasks, the reaction time increased correspondingly
What makes von Helmholtz’s demonstration a physiological experiment and Wundt’s a psychological experiment?
depends on the interpretation that each scientist made of his results
- Helmholtz = differences in rxn time in these two instances represent the effects of the speed of conduction of neural signalling (bc the toe is further from the brain than the thigh)
- Wundts = more psychological because as decisions become more complex, reaction time increased
what was Wundt the first to believe
believe that conscious experience could be studied scientifically + conducted the first documented psychological experiment
- believed that humans were capable of deciding what to attend to and this is what is perceived clearly
= voluntarism
what is voluntarism
an approach that emphasizes the role of will and choice in determining thoughts, perceptions and behaviours
- refers to the idea that the mind actively organizes information and experiences
- mental processes are not just reactions to stimuli but are driven by will
what is the theory of structuralism
the mind is broken down into the smallest basic components to understand the structure of the mind
- Edward Tichnener - student of Wundt
- can be broken down into 3 types of mental elements (sensations, images, feelings) and each of these can be broken down further into their fundamental properties
what are the 3 mental elements that Titchener
sensations
images
feelings
Who is John Wallace Bird
Canadian psychologist who studied under Titchener for the structuralist approach
- he was president of the American Psychological Association but he has been forgotten due to the part of devaluation of the structuralist approach
