Research about the psychological processes underlying behavior
Science
Activity that includes the systematic ways in which we go about gathering data, noting relationships, and offering explanations
Scientia
Latin word of science, which means Knowledge
Formal laboratory experiments
Designed to provide the most precise information
Observations
Under different conditions such as laboratory or real-world settings
We collect and use psychological data to understand the behavior of others and to guide our own behavior
Commonsense psychology
The kind of everyday, nonscientific data gathering that shapes our expectations and beliefs and directs our behavior toward others
Commonsense beliefs
Data we collect from our own experience and what we have learned from others
Very often, the data we gather as commonsense psychologist come from sources that seem credible and trustworthy
Psychological information, particularly when it is offered by people we like, respect, or admire, is typically accepted without question
Confirmation bias
Once we believe we know something, we tend to overlook instances that might disconfirm our beliefs and we seek, instead, confirmatory instances of behavior
If we were to rely only on commonsense psychology, we would frequently be wrong
All commonsense psychologists are trait theorists-at least when it comes to explaining the behavior of others
Our ability to make accurate predictions about someone's traits increases with the length of acquaintanceship. We are generally more accurate when we know someone well than when we judge a stranger
For decades, psychologists have debated whether traits or situations are better are better predictors of behavior
The process of stereotyping is a related problem of nonscientific inference
Overconfidence bias
The more data we have available (accurate or not), the more confidence we have in our judgments about behavior
Scientific Mentality
Research psychologists share the belief that there are specifiable (although not necessarily simple or obvious) causes for the way people behave and that these causes can be discovered through research
Empirical Data
Data that are observable or experienced
Aristotle advocated systematic observation of experience. Empirical data must be verified or disproved through investigation (Falsifiability)
Laws
When principles have generality to apply in all situations
Theory
We advance understanding and testing an interim explanation commonly
Parsimony
When two explanations are equally defensible, the simplest explanation is preferred until it is ruled out by conflicting data. "Occam's Razor"
Self-correction
Modern scientists accept the uncertainty of their own conclusions
Scientists meet frequently through professional and special interest groups and attend professional conferences to exchange information about their current work
Replication
To repeat our procedures and get the same results again if we have gathered data objectively and if we have followed good thinking
Goals of Psychological Science
Description
Prediction
Explanation
Control
Description
The initial step toward understanding any phenomenon, whether it is the path of the stars in heavens or complexities of human and animal behavior
Prediction
The capacity for knowing in advance when certain behaviors would be expected to occur – to be able to predict them ahead of time – because we have identified other conditions with which the behaviors are linked or associated
Explanation
When we explain behavior, we also understand what causes it to occur. It includes knowledge of the conditions that reliably reproduce the occurrence of a behavior
Control
The application of what has been learned about behavior. Once a behavior has been explained through experimentation, it may be possible to use that knowledge to effect change or improve behavior
Exposure Therapy
Exposure to the anxiety-provoking situation or stimuli
Systematic Desensitization
Exposure to the anxiety-provoking situation or stimuli with engagement in relaxation behaviors
Basic Research
Research designed to test theories or to explain psychological phenomena in humans and animals
Applied Research
Research that is designed to solve real-world problems (like improving employee performance)
Tools of Psychological Science
Observation
Measurement
Experimentation
Observation
The systematic noting and recording of events
Measurement
The assignment of numerical values to objects or events in their characteristics according to conventional rules
Experimentation
A process undertaken to test a hypothesis that particular behavioral events will occur reliably in certain, specifiable situations
