Unit 1: Reading and Notes Flashcards
Empiricism
What we know comes from experience, and that observation and experimentation enable scientific knowledge
Structuralism
Early school of though promoted by Wundt and Titchener; used introspection to reveal the structure of the human mind
Functionalism
Early school of though promoted by James and influenced by Darwin; explored how mental and behavioral processes function - how they enable the organism to adapt, survive, and flourish
Experimental Psychologists
The study of behavior and thinking using the experimental method
Behaviorism
The view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes . Most research psychologists today agree with (1) but not with (2)
Humanistic Psychology
A historically significant perspective that emphasized the growth potential of healthy people
Cognitive Neuroscience
The interdisciplinary study of the brain activity linked with cognition
Psychology
The science of behavior and mental processes
Nature-nurture issue
The debate over whether the human personality is based off the way you were raised and the experiences you had as a young child or if it’s based off your genes
Nature-Nurture example
While some psychologists believe it is nature that shapes a human’s personality, others believe it is nurture that shapes personality. Some believe it is both.
Biopsychosocial approach
An integrated approach that incorporates biological, psychological, and social-cultural levels of analysis
Biosychosocial approach
Someone can be the way they are because of biological, psychological, and social-cultural influences
Hindsight Bias
The tendency to believe, after learning an outcome, that one would have foreseen it.
Hindsight Bias Example
After the stock market drops, people say it was “due for correction”
Critical Thinking
Thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, assesses the source, discerns hidden values, evaluates evidence, and assesses conclusions
Critical Thinking Example
Looking up the facts behind information before taking it as true
Are humans overconfident when it comes to their intelligence
Yes, humans are overconfident when it comes to their intelligence. For example, only 40% of predictions made by experts with 80% confidence were true.
Why are humans prone to perceive patterns in the world?
Humans are prone to perceive patterns in the world because of our natural need to make sense of it all
How does the scientific attitude contribute to critical thinking
The scientific attitude tells you to believe with skepticism, which is one of the main points of critical thinking
Case Study: Strengths vs. Weakness
Strength: shows us what can happen
Weakness: individual cases may mislead us if the individual is atypical
Naturalistic Observation: Strengths vs. Weakness
Strength: Describes behavior without any interference
Weakness: Does not explain behavior
Surveys: Strengths vs. Weakness
Strength: looks at many cases
Weakness: the way a question is framed can have major effects
What is the purpose of a hypothesis in an experiment?
To create a prediction which can be tested. The prediction is often created based on a theory
What is an operational definition and how can this affect the results in an experiment?
An operational definition is a carefully wondered statement of the exact procedures used in a research study. This can affect the results in an experiment because it allows anyone to replicate it, therefore allowing the experiment to be further proved or disproved
What are the different sampling methods and which one is generally the most effective?
Different sampling methods are the methods in which the people who take the survey are selected. The most effective sampling method is the random sample because it fairly represents the population.
Scatterplot
A graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggest the direction of the relationship between two variables. The amount of scatter suggest the strength of the correlation
Correlation
A measure of the extent to which two variables change together, and thus of how well either variable predicts the other
What is the difference between correlation and causation
Correlation is when one variable is present at the same time another variable is present. Causation is when one variable causes another variable
What is illusory correlation and provide an example
Illusory correlation is the perception of a relationship where none exists. For example, when people believe bad weather causes arthritis, they are only remembering the times that arthritis was present at the same time as bad weather, not when it wasn’t
Explain the difference between the experimental ground and the control group
The experimental group is the group where the independent variable is changed. The control group is the group where the independent variable is not changed
Double-Blind procedure
An experimental procedure in which both the research participants and the research staff are ignorant about whether the research participates have received the treatment or a placebo
Placebo Effect
Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active
Validity
The extent to which a test or experiment measures or predicts what it is supposed to
What can be the dangers of statistical illiteracy?
Because it can lead people to misanalyze data and believe something that is not true as fact
What is descriptive statistics and what are some ways to organize data?
Descriptive statistics is numerical data used to measure and describe characteristics of groups. Some ways to organize data are with a bar graph or the mean, median, and mode
How can data be skewed?
Data can be skewed if there are a low number of inputs in a large standard deviation
Range
The difference between the highest and lowest scores in a distribution
Standard Deviation
A computed measure of how much scores vary around the mean score
Inferential statistics
Numerical data that allows one to generalize - to infer from a sample of data the probability of something being true of a population
Statistical significance
A statistical statement of how likely it is that an obtained result occurred by chance
Explain the difference between descriptive and inferential statistics in research
Descriptive statistics is numerical data that describes characteristics in groups and inferential statistics is data that allows you to see the probability of the descriptive statistics being true
Informed Consent
An ethical principle that research participants be told enough to enable them to choose whether they wish to participate
Debrief
The post experimental explanation of a study, including its purpose and any deceptions, to its participants
