Some notes and speculations about various topics. ||| Gegenwärtig - vorübergehend -
wohl eher eine Gedankensammlung als ein Naturwissenschaftsblog. Das Konzept eines "Naturwissenschaftsblogs" wird erst im kommenden Jahr (2018/2019) Umsetzung finden.

Storage capacity explains fluid intelligence but executice control does not Adam Chuderski et al., 2012
"The present study has supported the theories of fluid intelligence assuming thatthe crucial cognitive mechanism underlying fluid ability lies in storage capacity, which enables people to actively maintain distinct chunks of information and flexibly construct task-relevant bindings among them. In the two large-scale psychometric studies reported in this paper, storage capacity accounted for on average 70% of variance in fluid intelligence. On the contrary, no support has been found for the theories looking for the mechanisms responsible for intelligence in the domain of effectiveness of executive control. The measures of control were either not significantly related to fluid ability, as in the case of interference resolution and response inhibition, or fully depended on individual storage capacity, as in the case of attention control."
