The transfer can occur across domains, [16] paradigms, [41] and help retention for material not on a final test. [42] Using retrieval practices also produces less forgetting than studying and restudying [43] while helping to identify misconceptions and errors [44] [45] [46] with effects lasting years. [47]
Testing a hypothesis suggested by the data can very easily result in false positives (type I errors). If one looks long enough and in enough different places, eventually data can be found to support any hypothesis. Yet, these positive data do not by themselves constitute evidence that the hypothesis is correct. The negative test data that were ...
The typical steps involved in performing a frequentist hypothesis test in practice are: Define a hypothesis (claim which is testable using data). Select a relevant statistical test with associated test statistic T. Derive the distribution of the test statistic under the null hypothesis from the assumptions.
The hippocampus has been implicated as a key structure for spatial memory in humans, and studying behavior in food caching birds and other animals has been extremely influential on this view. [ 27 ] [ 38 ] Sherry and his colleagues were also able to show that food-caching birds have much larger hippocampus’ than non food-caching birds.
investigations that do or do not provide a potentially falsifying test of the hypothesis. [7] Evidence contrary to a hypothesis is itself philosophically problematic. Such evidence is called a falsification of the hypothesis. However, under the theory of confirmation holism it is always possible to save a given hypothesis from falsification ...
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
Given this, it is best to understand that presently functional traits might not all have been produced by natural selection. [3] The term "function" is preferable to "adaptation", because adaptation is often construed as implying that it was selected for due to past function. This corresponds to Aristotle's final cause.

The process discourages the analyst from choosing one "likely" hypothesis and using evidence to prove its accuracy. Cognitive bias is minimized when all possible hypotheses are considered. [1] Evidence – The analyst then lists evidence and arguments (including assumptions and logical deductions) for and against each hypothesis. [1]
