Document Summary
Correlational studies measure the strength and direction of relationships between two variables. Time that passes between stimulus presentation and response. Intended to measure the complexity of mental processes. The duration of a task relates to the number of and difficulty of steps of a mental process. Measured through speech onset time, button press time, eye movement time, other methods. Number/percentage and kinds of correct and incorrect answers. There is a relationship between accuracy and the difficulty of tasks/number of tasks. Considered as a confounding variable in experiments. Publication bias: a preference for significant effects - exists. Researchers will look at an experiment and didn"t get good results so they hide it and do not publish it. Nonsignificant effects that do not support hypotheses end up in the. No one knows about the study; failures are actually informative. Better to talk about the successes and failures so others know that it has already been tried.
