chapter 1 Flashcards
what is the definition of psychology?
the scientific study of scientific behaviour, thought, and experience and how they can be affected by physical, mental, social and environmental factors
what are 6 overarching goals of psychology?
to understand how different brain structures work together to produce our behaviour
to understand how nature (genetics) and nurture (our upbringing and environment) interact to make us who we are
to understand how previous experiences influence how we think and act
to understand how groups- family, culture and crowds affect the individual
to understand how feelings of control can influence happiness and health
to understand how each of these factors can influence our well-being and could contribute to psychological disorders
what are the 3 things psychology can help you understand?
why other people act the way they do
the factors that influence you and others
how to gain a better understanding and acceptance of the people around you
a person who carefully follows a system of observing, conducting, predicting and testing. is conducting what?
they are conducting science
what determines wither a specific type if research is scientific?
the scientific method
what is the scientific method?
a way of learning about the world through collecting observations, developing theories to explain them, and using the theories to make predictions
what involves a dynamic interaction between hypothesis testing and the construction of theories?
the scientific method
explain the scientific method?
you start with a theory, then it turns in to a hypothesis, then you test the hypothesis and you either confirm hypothesis or reject hypothesis
if you confirm the hypothesis through testing it in the scientific method what would you do next?
either generate another new hypothesis or confirm and strengthen original theory
if you reject the hypothesis through testing it in the scientific method what would you do next?
either discard or modify original hypothesis or revise original theory
what does scientific thinking and procedures revolve around?
a hypothesis and a theory
what guides the process and progress of the sciences?
a hypothesis and a theory
what is a hypothesis?
a testable prediction about processes that can be observed and measured
can you prove a hypothesis?
no, it can only be supported or rejected because a future experiment could show that it is wrong or limited in some way
when does the support or rejection of a hypothesis occur?
after scientists have tested the hypothesis
what is required for a hypothesis to be testable?
it has to be falsifiable
what is the definition of falsifiable?
the hypothesis is precise enough that it could be proven false
why does a hypothesis need to be falsifiable?
to it can be testable but also because it will help future researchers if they try to replicate the study to determine if the results were due to chance
what are 3 examples of good scientific hypothesis?
people become less likely to help a stranger if others are around
alcohol reduces the quality of sleep
exercise improves memory
(these are good because they can be confirmed or rejected through testing)
what is pseudoscience?
an idea that is presented as science but does not actually utilize basic principles of scientific thinking or procedure
what is a theory?
an explanation for a broad range of observations that also generate new hypotheses and integrates numerous findings into a coherent whole
(general principles or explanations of some aspect of the world)
what is an essential quality of scientific theories?
they can be supported or proved false with new evidence
if a hypothesis is supported or rejected how does that impact the theory?
supported: if the hypothesis is supported it provides more support to the theory, good theories eventually become accepted explanations of behaviour
rejected: if the hypothesis is not supported then researchers may have to rethink elements of the theory
why is hypothesis testing important?
because testing a hypothesis helps ensure science is self correcting so bad ideas do not last long
what are 3 common misperceptions about theories?
theories are the same as opinions or beliefs
(this is not true because a theory can help scientists develop a testable theory, options cannot and don’t need to testable or logical)
all theories are equally plausible
(not true because scientists come up with theories as to why depression exists, Joel cannot say his theory and claim equal status)
the quality of a theory is related to the number of people who believe it
(not true just because people believe something doesn’t mean its true)
because our thoughts and behaviours have multiple influences, what have psychologist adopted?
multiple perspectives to understand them
what is the biopsychosocial model?
a means of explaining behaviour as a product of biological, psychological and sociocultural factors
what are 4 biological factors that influence our behaviour?
brain structures
chemicals
hormones
external substances (drugs)
what are 3 psychological influences that shape the way we think and respond to people and situations?
memories
emotions
personalities
what are 4 sociocultural factors that effect our behaviour?
family
peers
ethnicity
culture
what is one of the most challenging aspects of psychology?
dealing with biological, psychological and sociocultural factors affecting your brain all at once
what are the 3 main factors impacting your brain on a daily basis?
biological
psychological
sociocultural
what is scientific literacy?
the ability to understand, analyze and apply scientific information
what are the 4 key components of the scientific literacy model?
knowledge gathering (how do we know about this)
scientific explanation (how can science explain it)
critical thinking (can we critically evaluate the evidence)
application (why is this relevant)
why is the scientific literacy method important?
it allows us to separate information that we should find convincing from the bad information
allows us to better analyze the information presented by politicians, corporations and the media, making it more difficult for these groups to influence you
allows us to apply the results of scientific studies to different situations
what is an example of the first stage “knowledge gathering” in the scientific literacy model?
gathering information on students study methods for exams
what is an example of the second stage “scientific explanation” in the scientific literacy model?
after gathering the information on students study methods, examine wether the information that is available about a topic has been tested in scientific studies
what is an example of the third stage “critical thinking” in the scientific literacy model?
after we examine the information that has been scientifically tested, we examine the limitations of the studies and look for alternative explanations
what is an example of the fourth stage “application” in the scientific literacy process?
you attempt to apply the results to situations outside the laboratory and to the real world
what are 3 examples of misinformation?
“fish oil supplements can fight off memory problems in old age”
“how can they say corporal punishment is bad? I was spanked as a kid and I turned out fine”
“covid-19 is just like the common flu. I don’t wear a mask to prevent the flu, why should I wear one to fight covid?”
what is critical thinking?
involves exercising curiosity and skepticism when evaluating the claims of others, and with our own assumptions and beliefs
does critical thinking mean being negative or critical?
it does not mean being negative or critical, rather it means that you intentionally examine knowledge, beliefs and the means by which conclusions were obtained
what are the 6 steps in critical thinking?
be curious
examine the nature and source of the evidence
examine assumptions and biases
avoid overly emotional thinking
tolerate ambiguity
consider alternative view points and alternative interpretations of the evidence
explain and give an example the “be curious” step in critical thinking?
simple answers are sometimes to simple and common sense is not always correct, you need to be curious and seek out multiple answers
EG. giving your brain some time to rest after having a stroke hinders rather than helps recovery
explain and give an example the step “examine the nature and sources of the evidence” in critical thinking?
not all research is of equal quality, it may be coming from a bad source
EG. some studies use flawed methods or in the case of infamous study linking vaccines and autism, were performed by someone who would benefit financially if the results told a particular story
explain and give an example the step “examine assumptions and biases” in critical thinking?
this includes your own assumptions and biases as well as the assumptions of those making the claims
EG. research examining the impact of human behaviour on climate change may be biased if it I sounded by oil companies
explain and give an example of the step “avoid overly emotional thinking” in critical thinking?
emotions can tell us what we value, but thy are not always helpful when making critical decisions
EG. you may have strong responses when hearing about differences in the cognitive abilities between genders, however it is important to put those aside to examine the studies themselves
explain and give an example of the step “tolerate ambiguity” in critical thinking?
most complex issue do not have clear-cut answers and may need to find multiple answers to form your own opinion
EG. psychologists have identified a number of factors leading to depression, but no single factor guarantees that a person will suffer from this condition
give an example of the step “consider alternative view points and interpretations of the evidence”?
it is clear that we require sleep in order to function properly, however there are several theories that can explain the function that sleep serves
what is the principle of parsimony?
an idea that the simplest of all competing explanations (the most parsimonious) of a phenomenon should be the one we accept
what are the 2 fundamental beliefs psychological science stems from?
empiricism
determinism
what is empiricism?
a philosophical tenet that knowledge comes through experience
explain empiricism?
empiricism means that knowledge about the world is based on careful observation, not on common sense or speculation. whatever we see or measure should be observable by anyone else who follows the same method
what is determinism?
the belief that all events are governed by lawful, cause and effect relationships
what is an example of determinism?
if you smell cookies (cause) you might show signs of hunger (effect)
that do psychologists recognize human behaviour to be influenced by?
internal and external influences
who made the first observation of brain damage leading to vastly different impairments?
ancient Egyptian doctors
when and who created the worlds first personality classification scheme?
the physician hippocrities ( 460-370 BCE)
what where the 4 humours or fluids that the greeks believed to influenced both health and personality (temperaments)?
blood
yellow bile
black bile
phlegm
