The tendency to believe, after learning an outcome, that one would have foreseen it. (Also known as the I-knew-it all-along-phenomenon) *Example: September 11th Thinking that does not blindly accept arguments and conclusion. Rather, it examines assumptions, discerns hidden values, evaluates evidence, and assesses conclusion. *Example: An explanation using an integrated set of principles that organizes observations and predicts behaviors or events. *Example: A testable prediction, often implied by a theory. *Example: A statement of the procedures (operations) used to define research variables. *Example: Human Intelligence may be operationally defined as what ban intelligence test measures.

Independent and Dependent Variables An independent variable is a factor that is manipulated in an experiment.? The experimenter controls whether or not subjects are exposed to the independent variable.?? The dependent variable is measured to determine if the manipulation of the independent variable had any effect.? For example,?? to test a hypothesis that eating carrots improves vision, the experimenter would manipulate whether or not subjects ate carrots.? Thus, eating carrots is the independent variable.? Each subject?s vision would be tested to see if carrot eating had any effect.? Thus, vision is the dependent variable.? The subjects assigned to eat carrots are in the experimental group, whereas subjects not eating carrots are in the control group. ?

Psychology is empirical. Psychologists are committed to addressing questions about behavior through formal, systematic observation The scientific approach assumes that events are governed by some lawful order Psychologists and other scientists share three sets of interrelated goals: Measurement and description Understanding and prediction A hypothesis is a tentative statement about the relationship between two or more variables. Variables are any measurable conditions, events, characteristics, or behaviors that are controlled or observed in a study Application and control A theory is a system of interrelated ideas used to explain a set of observations. Allows to leap from description of behavior to understanding Must be testable Gradual construction

Chapter Two What is science? Science: ? is a methodical, logical process for producing knowledge about natural phenomena ? a cumulative body of knowledge ----- Table 2.1 : Basic Principles of Science (7) Science depends on skepticism and accuracy ? Ideally scientists are skeptical and un biased. ? Scientist strive for ? Accuracy- correctness of measurement ? Reproducibility- Repeatability of result : Repeating studies or tests is called replication Deductive and inductive reasoning ? Deductive reasoning- logical reasoning from general to specific ? Inductive reasoning- reasoning from many observations to produce a general rule ? It is also important to recognize the role of insight, creativity, aesthetics, and luck in research
