They start from the (still controversial) hypothesis that the symptoms of autism are linked to an increased ratio of neural excitation to inhibition, which would result in a reduced impact of the inhibitory or suppressive pool in the DN equation. As is clear from Eq. 1, decreased DN can ...
The null hypothesis (H₀) is a fundamental concept in statistics and A/B testing, representing the assumption that no significant difference or effect exists between two compared groups or variables. It serves as the default position in an experiment, indicating that any observed variation is due...
hypothesis, participants in a control condition completed the experiment without the possibility of selecting or watching any video or clips. I found that the information did affect subsequent choices. Raising the incentive caused participation to increase by 33 percentage points (from 38% to 71%;t...

Both types of project require different data to be successful: drug discovery is based on solidly established relationships (be they of a statistical or mechanistic nature), whereas exploratory projects are often hypothesis-free and do not require actionable consequences, at least in the first ...

Typing has become a pervasive mode of language production worldwide, with keyboards fully integrated in a large part of many daily activities. The bulk of the literature on typing expertise concerns highly trained professional touch-typists, but contempo
When testing this hypothesis, results indicate that the sheer availability of TCOC information has no significant effect on the choice of whether to buy a BEV (model 1: p = 0.707 and model 2: p = 0.060). However, the TCOC information weighted with the TCOC value difference shows a ...
