| 7227176673 | empiricism+ | The philosophical idea that knowledge originates in experience, and that science, therefore, should rely on observation and experimentation; the theory that you can only have knowledge if you have concrete evidence and have experienced it. Often contrasted against rationalism. | | 0 |
| 7227163099 | Gestalt+ | From a German word that means "whole" or "form" or "configuration." This was the name given to a school of psychology founded by Max Wertheimer which believed that much of perception is shaped by innate factors built into the brain. It sought to understand how the brain works by studying perception and perceptual learning, believing that "percepts" consist of meaningful wholes. For example, the theory that we perceive concepts as a whole rather than perceiving the individual parts (e.g. a "group" rather than "five people standing together"). | | 1 |
| 7242704304 | nature-nurture debate+ | The long-standing controversy over the relative contributions that genes and experience make to the development of psychological traits and behaviors. Most theorists today believe that traits an behaviors arise from and interaction of the two. | | 2 |

A theory on why something has occurred; can be proven right or wrong; an educated guess or prediction on what is going to happen in an experiment; an explanation made on the basis of limited evidence that acts as a starting point for further investigation. Generally measurable and preferably written in "If...then" format. | | 5 |
| 7242716547 | correlation coefficient+ | A statistical index (a measurement or mathematical expression) of the relationship between two variables. A range from -1 to +1 is used to show the strength of a relationship (NOT the cause and effect) between two variables; often symbolized as "r."

| 7242758410 | dependent variable (DV)+ | The outcome factor -- the variable that may change in response to manipulations of the independent variable. Often identified by the value "y;" it's value depends on that of another variable. | | 11 |
| 7242758668 | independent variable (IV)+ | The experimental factor or condition in a scientific study that is manipulated so that its effects nay be observed; often identified by "x." This is the experimental factor that is manipulated - the variable whose effect is being studied. | | 12 |
| 7242739983 | placebo effect+ | Any effect that seems to be a consequence of an inert substance or condition, which the recipient assumes is an active agent. Any experimental results are caused by expectations alone. | | 13 |
| 7232838155 | significant difference or statistical significance+ | A statistical statement of how likely it is that an experimental result occurred by chance; this shows that the independent variable (IV) made a real difference in the dependent variable (DV). An experiment's data qualifies as this if (when assuming that the hypothesis is false - a null hypothesis) a probability value (p-value) is less than .05, or 5%. | | 14 |

| 7227081622 | evolution+ | The gradual process of biological change that occurs over time in a species as it adapts to its environment. Driven by natural selection, this affects the physical and mental processes of organisms over time, as well as their behaviors. Organisms with the greatest chance of survival live long enough to breed and pass on their genes. | | 29 |
| 7227070715 | natural selection+ | The driving force behind evolution, by which the environment "selects" the fittest organism. Traits represented in the population are based off of the "survival of the fittest." Individuals well adapted to their environment are more likely to reproduce than individuals who are not well adapted. This means that the genes and traits of well adapted individuals are more likely to be passed down to the next generation, making their genes more prevalent in the population. | | 30 |

| 7232842522 | distance cues+ | Reference points that allow us to judge distance. Our brains use retinal disparity (or the lack of it), relative size, interposition (layering), linear perspective, relative height and motion, and light and shadow all to calculate distance. | | 37 |
| 7279366163 | perceptual constancy+ | Perceiving objects as unchanging (having consistent shapes, size, brightness and color) even as illumination and retinal images change (a door seen from an angle is not actually rectangular - but our brain knows that it is). | | 38 |

| 7279456644 | extinction+ | The diminishing and disappearance of a conditioned response. In classical conditioning, this occurs when an unconditioned stimulus does not follow a conditioned stimulus. In operant conditioning, this occurs when a response is no longer reinforced. | | 47 |
| 7279474145 | operant conditioning+ | A type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher. | | 48 |
| 7297216870 | law of effect+ | Thorndike's principle that (in operant conditioning) behaviors which are followed by favorable consequences are more likely to be repeated; conversely, behaviors which are followed by unfavorable consequences are less likely to be repeated. | | 49 |
