DESCRIPTION:Cluster-Based Permutation Tests are an attractive tool for sta
 tistical analysis of results from neuroimaging experiments. However\, desp
 ite their upsides\, they are routinely employed to justify claims which th
 ey - by design - cannot answer\; in particular\, claims about the temporal
  or spatial extent of effects. I will discuss what claims are and are not 
 justified by the outcomes of such tests\, how to think about them\, and pr
 ovide an outline of how to report these tests in a scientific paper or pre
 sentation. I will also briefly discuss some recent developments and altern
 atives. \n\nWhile basic knowledge of how Cluster-Based Permutation Tests a
 re employed in cognitive neuroscience will be helpful for following this p
 resentation\, I will develop the core issues in a very basic manner\, and 
 little understanding of mathematical statistics is expected.
