Pyschology

is the science of behavior and mental processes.

a research perspective whose major explanatory focus is how the brain, nervous system, and other physiological mechanisms produce behavior and mental processes.

a research perspective whose major explanatory focus is how mental processes, such as perception, memory, and problem solving, work and impact behavior.

a research perspective whose major explanatory focus is how external environmental events condition observable behavior.

a research perspective whose major explantory focus is how other people and the cultrural context impact behavior and mental processes

The tendency, after learning about an outcome, to be overconfident in one's ability to have predicited it.

research methods whose main purpose is to provide objective and detailed descriptions of behavior and mental processes

a descriptive research method in which the behavior of interest is observed in its natural setting, and the researcher does not intervene in the behavior being observed.

a descriptive research method in which the observer becomes part of the group being observed.

a descriptive research method in which the researcher studies an individual in depth over an extended period of time

a descriptive research method in which the researcher uses questionnaires and interviews to collect info about the behavior, beliefs, and attitudes of particular groups of people.

the entire group of people that a researcher is studying

the subset of a population that actually particpates in a research study.

a sampling technique that obtains a represtative sample of a population by ensuring that each individual in a population has an equal opportuntiy to be in the sample

a research study in which two variables are measured to determine if they are related

any factor that can take on more than one value.

a statistic that tells us the type and the strength  of the relationship between two variable.

a direct relationship between two variables

an iverse relationship between two variables.

a visual depiction of correlational data in which each data point represents the scores on the two variables for each participant

an explanation of a correlatation between two variables in terms of another variable that could possibly be responsible for the observed relationship between the two variables.

a control measurue in which participants are randomly assigned to groups in order to equalize participant characteristics across the various groups in an experiment.

in an experiment, the variable that is a hypothesized cause and thus is manipulated by the experimenter.

in an experimentt, a variable that is hypothesized to be affected by the indendent variable and thus is measured by the experimenter

a research method in which the researcher manipulates one or more independent variables and measures their effect on one or more dependent variables while controlling other potentially reievent variables.

in an experiment the group exposed to the independent variable

in a experiment the group not exposed to the independent variable.

a description of the operations or procedures that a reseacher uses to manipulate or measure a variable

improvement due to the expectation of improving because of receiving treatment.

a control group of participants who believe they are receiving trements, but who are only receiving a placebo.

an inactive pill or a treatment that has no known effects.

statistical analyses that allow researches to draw conclusions about the results of a study by determining the probability the results are due to random variations. The results are statistically significant if this probability is .05 or less

a statistical technique that combines the results of a large number of studies on one experimental question into one analysis to arrive at an overall conclusion.
