Abstract:
Leibovich et al. propose that continuous magnitudes and a number sense are used holistically to judge numerosity. We point out that their proposal is incomplete and implausible: incomplete, as it does not explain how continuous magnitudes are calculated; implausible, as it cannot explain performance in estimation tasks. We propose that we do not possess a number sense. Instead, we assume that numerosity judgments are accomplished by weighing the different continuous magnitudes constituting numerosity.

Sympathetic Division of the ANS
Originating in the thoracic and lumbar spinal cord segments, the preganglionic fibers of the sympathetic division exit the spinal cord through the white ramus communicans. They then enter the...

Null and Alternative Hypotheses
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...
