| The branch of genetics that examines the genetic an d environmental contributions to a persons character and behavior. | ||
| In an experiment, any variable other than the independent variable that creates differences between the experimental and control groups. | ||
| A movement in psychology led by William James in which consciousness was studied according to the functions it serves, rather than its structures. | ||
| A statistic that measures the variability, or degree of spread, of a distribution. It is calculated by taking the square root of the variance, or the average squared deviation of scores from the mean. | ||
| The ability of a test to measure what it is purported to measure. | ||
| Research that is conducted to solve a specific or practical problem. | ||
| The branch of psychology that deals with the diagnosis and treatment of psychological disorders. | ||
| A movement in psychology that was characterized by a deep concern for human beings, their dignity, and their universal struggles. Abraham Maslow and Carl Rogers were two key figures in this movement. | ||
| A concrete definition of a variable for the purposes of a particular experiment. | ||
| A theoretical perspective that focuses on unconscious mental processes, as well as the impact of early childhood experiences on later personality and behavior. | ||
| In an experiment, every participant has an equal opportunity to be assigned to a particular group. Random assignment to groups is the hallmark of a "true experiment." | ||
| A plan for how to conduct the scientific investigation, how the variables will be manipulated and/or measured, as well as how the data will be collected and analyzed. | ||
| The pursuit of knowledge and understanding, using systematic methods of inquiry. | ||
| A condition in which the difference between the experimental and control groups is so large that it is unlikely to have occurred by chance alone. | ||
| Research that is conducted for the sake of knowledge itself, rather than to solve a specific or practical problem. | ||
| Statistics that provide information about the features of a particular sample. | ||
| In an experiment, the group that is exposed to the independent variable. | ||
| The scientific study of behavior and mental processes. | ||
| A method of sampling in which every member of a population has an equal chance of being selected for the sample. | ||
| A philosophical approach that says that nothing can be known with absolute certainty. In general, it refers to a doubting or questioning attitude. | ||
| A movement in psychology, led by Wilhelm Wundt, that focused on analyzing conscious experience in terms of its fundamental structures. | ||
| A situation in which two variables are correlated, but neither one of them caused the other. They were both caused by another, different variable. If A and B are correlated, then C caused A and B. | ||
| A statistic that measures the variability, or degree of spread, in the distribution. It is calculated by taking the average squared deviation of scores from the mean |
