Samenvatting

Many argue that there is a reproducibility crisis in
psychology. We investigated nine well-known effects from the
cognitive psychology literature—three each from the domains
of perception/action,memory, and language, respectively—and
found that they are highly reproducible. Not only can they be
reproduced in online environments, but they also can be
reproduced with nonnaïve participants with no reduction of
effect size. Apparently, some cognitive tasks are so constraining
that they encapsulate behavior from external influences, such as
testing situation and prior recent experience with the experiment
to yield highly robust effects.
