Structuralism
The first school of psychology and focused on breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection
Functionalism
The doctrine that what makes something a thought, desire, pain (or any other type of mental state) depends not on its internal constitution, but solely on its function, or the role it plays, in the cognitive system of which it is a part.
Humanism
Focuses on each individual's potential and stresses the importance of growth and self-actualization.
Biological
Psychological specialty focused on the physical and chemical changes that cause, and occur in response to, behavior and mental processes.
Evolutionary
Study of the evolution of behavior and the mind, using principles of natural selection.
Cognitive
A branch of psychology concerned with the scientific study of the mind - that includes such mental processes as perception, attention, memory, language, problem solving, etc.
Informed Consent
Participants must be told and give their consent to the: purpose of research, procedures that will be used, risks or potential discomforts, and length of time involved
Limit Deception
If the participants are deceived in any way about the nature of the study, the deception must not be so extreme as to invalidate the informed consent
No Coercion
Participants must know that they are involved in research and give their consent
Protect from Harm
All psychologists have the ethical obligation to ensure that their participants are safe from psychological and physiological harm.
Case Study
In-depth investigations of a single person, group, event or community.
Advantage: Emphasize in-depth content. The researcher is able to delve deep and use a variety of data sources to get a complete picture.
Disadvantage: The uniqueness of the data usually means that it is not able to be replicated.
Survey
Data collection instruments designed to assess a population's attitudes, belief, and or opinions about particular topics.
Advantage: Having a large population and therefore a greater statistical power, the ability to gather large amounts of information and having the availability of validated models.
Disadvantage: They rely on self-reported data, which can be affected by various sources of bias, such as social desirability, recall, or response styles.
Naturalistic Observation
A research method in which the researcher studies behavior in its natural setting without intervention or manipulation
Advantage: Allows the investigators to directly observe the subject in a natural setting
Disadvantage: Lack of scientific control, ethical considerations, and potential for bias from observers and subjects.
Hindsight Bias
When you think you knew something all along after the outcome has occurred.
Overconfidence
The tendency to be more confident than correct and to overestimate the accuracy of our beliefs and judgements.
Confirmation Bias
The tendency of individuals to support or search for information that aligns with their opinions and ignore information that doesn't
Confidentiality
The obligation of psychologists to protect clients from unauthorized disclosure of information revealed in the context of the professional relationship.
Experimental Group
The group receiving or reacting to the independent variable in an experiment
Control Group
The group that does not receive the independent variable in an experiment.
Independent Variable
The variable manipulated by the experimenter
Dependent Variable
The variable that is affected by the dependant variable
Random Assignment
Every participant having an equal chance of being in either the experimental group or the control group.
Random Selection
A method of selecting a sample from a population
Single-Blind Study
The subjects do not know, but the researcher is aware as to which group everyone is in
Double Blind Study
The subject nor the researcher is aware as to which group anyone is in
Confounding Variables
A variable, other than the independent variable, that could influence the dependent variable
Mean
Average of all the scores in the distribution
Median
The middle value in a data set
Mode
The most often occurring number in a data set
Range
The gap between the lowest and highest scores.
Standard Deviation
A statistical measure of the amount of dispersion in a set of scores
Inferential Statistics (Do my results matter?)
The analysis of a random sample of data taken from a population to describe and make inferences about the population
P<.05-
The probability of the null hypothesis being true is 1 in 20, or 5%
Correlations cannot show…
Causation!
Illusory Correlation
Perception of a relationship where none actually exists
Correlation Coefficient
A measure of the linear correlation between two variables X and Y, giving a value between +1 and −1 inclusive, where 1 is total positive correlation, 0 is no correlation, and −1 is total negative correlation.
Scatterplot
A graphed cluster of dots, each representing the values of two variables.
Experiments are the only research method that can show…
Cause and Effect!
r=
The strength of the correlation of a scatter plot
Margaret Floy Washburn
First woman to earn a Ph.D. in psychology
William Wundt
Set up first psychological laboratory in Leipzig, Germany in 1879; known for training subjects in introspection and for his theory of structuralism
William James
Published The Principles of Psychology, the science's first textbook; responsible for theory of functionalism
Mary Whiton Calkins
Studied with William James and went on to become president of the American Psychological Association
G. Stanley Hall
Student of William James who pioneered he study of child development and was the first president of the APA
Gestalt Psychology
Theory that states that the whole experience is often more than just the sum of the parts, because the way we experience the world is more than just an accumulation of various perceptual experiences; relatively little influence on current psychology
Max Wertheimer
Gestalt psychologist who argued against dividing human thought and behavior into discrete structures
Wolfgang Kohler
Gestalt psychologist who studied insight learning, an overlooked form of learning marked by sudden "Aha!" experiences
René Descartes
17th century French philosopher who asserted that human sensations and behaviors are based on activity in the nervous system
Aristotle
Ancient Greek philosopher who developed theories of sensation, perception, cognition, memory, problem solving, and ethics
Plato
Ancient Greek philosopher who studied areas like cognition; was first philosopher credited with the study of gaining knowledge
Jean Piaget
Came up with a cognitive developmental theory, which focuses on how our cognitions develop in stages as we mature
B.F. Skinner
Behaviorist who expanded the basic ideas of behaviorism to include the idea of reinforcement- environmental stimuli that either encourage or discourage certain responses
John Watson
Psychologist who believed the science must limit itself to observable phenomena; wanted to establish behaviorism as the dominant paradigm of psychology
Behaviorism
Theory that states psychologists should look at only behavior and causes of behavior, and not concern themselves with describing elements of consciousness; dominant school of thought in psychology from the 1920s through the 1960s
Sigmund Freud
Revolutionized psychology with his psychoanalytic theory; believed the unconscious mind must be examined through dream analysis, word association, and other psychoanalytic therapy techniques; criticized for being unscientific and creating unverifiable theories
Psychoanalysis
Theory that states a part of our mind over which we do not have conscious control determines, in part, how we think and behave
Introspection
First began in laboratory set up by Wilhelm Wundt; process of reporting on one's own conscious mental experiences
Charles Darwin
English scientist whose theory of evolution through natural selection was first published in 'On The Origin of the Species" in 1859.
Dorothea Dix
Tireless reformer, who worked mightily to improve the treatment of the mentally ill. Appointed superintendent of women nurses for the Union forces.
Ivan Pavlov
Discovered classical conditioning; trained dogs to salivate at the ringing of a bell. he pioneered the study of learning.
Carl Rogers
Leader of humanistic psychology rejected Freud's pessimistic view of human nature. Instead, offered the optimistic view that people are innately good, and, thus, "positivie, forwar-moving, constructive, realistic, and trustworthy". Argued that self-concept is the cornerstone of a person's peronality. People whose self-concept matches their life experiences usually have high self-esteem and better mental health. Influenced by Abraham Maslow, believed that people are motivated to achieve their full potential or self-actualize.
Experiment
Deliberately designed procedures used to test research hypotheses
Advantage: Experiments can be replicated and their reliability can be tested
Disadvantage: Extraneous variables cannot always be controlled, human responses can be difficult to measure, and participants may also cause bias.
Correlation
The statistical relationship between two variables
Advantage: Provide evidence for a potential causal relationship between two variables
Disadvantage: They cannot establish causal relationships nor direction of causal influence, there is no control of the variables, they don't explain behavior, and they could result in illusory correlations.
