Although the dynamic field model predicts infants' perseverative behavior in the context of the A-not-B manual search task, it does not account for infant perseveration in other contexts. An alternative cognitive capacity explanation for perseveration is more parsimonious. It accounts for the graded nature of perseverative responses and perseveration in different contexts.

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if (...) and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated. (shrink)
A critical examination of Susan Blackmoreâ€™s psi experiment database was undertaken to assess the claims of consistent â€œno ESPâ€ across these studies. Many inconsistencies in the experimental reports were found, and their serious consequences are discussed. Discrepancies were found between the unpublished experimental reports and their published counterparts. â€œFlawsâ€ were invoked to dismiss significant results while other flaws were ignored when studies produced nonsignificant results. Experiments that were admittedly flawed in the unpublished reports were mixed with supposedly unflawed studies and (...) published without segregation, creating the impression of methodological soundness. Two instances in which study chronology was reordered were found. Overall, it is concluded that Blackmoreâ€™s claims that her database shows no evidence of psi are unfounded, because the vast majority of her studies were carelessly designed, executed, and reported, and, in Blackmoreâ€™s own assessment, individually flawed. As such, no conclusions should be drawn from this database. (shrink)
The problem of the origin of life understandably counts as one of the most exciting questions in the natural sciences, but in spite of almost endless speculation on this subject, it is still far from its final solution. The complexity of the functional correlation between recent nucleic acids and proteins can e.g. give rise to the assumption that the genetic code (and life) could not originate on the Earth. It was Portelli (1975) who published the hypothesis that the genetic code (...) could not originate during the history of the Earth. In his opinion the recent genetic code represents the informational message transmitted by living systems of the previous cycle of the Universe. Here however, we defend the existence of a certain strategy in the syntheses of the genetic code during the history of the Earth. The strategy of correlation between amino acid and nucleotide polymers made an increasing velocity of the chemical evolution possible, that is, it increased the velocity of formation of the genetic code. Thus, life with the recent genetic code could originate on the Earth within the present cycle of the Universe. (shrink)
Open peer commentary on the article “Communication Emerging? On Simulating Structural Coupling in Multiple Contingency” by Manfred Füllsack. Upshot: Our criticism aims at the premises of Füllsack’s simulation model, i.e., we claim that his interpretation of the Luhmannian concept of double contingency contradicts the systems theoretical approach in fundamental ways. Neither the view of communication as an emergent system, nor the theory of double contingency is addressed in an adequate manner. Thus Füllsack in fact does not simulate a systems theoretical (...) approach to double contingency but simulates a mere reduction of the social to the individual psyches. (shrink)
Randomized Controlled Trials (RCTs) are currently the gold standard within evidence-based medicine. Usually, they are conducted as sequential trials allowing for monitoring for early signs of effectiveness or harm. However, evidence from early stopped trials is often charged with being biased towards implausibly large effects (e.g., Bassler et al. 2010). To our mind, this skeptical attitude is unfounded and caused by the failure to perform appropriate conditioning in the statistical analysis of the evidence. We contend that a shift from unconditional (...) hypothesis tests in the style of Neyman and Pearson to conditional hypothesis tests (Berger, Brown and Wolpert 1994) gives a superior appreciation of the obtained evidence and significantly improves the practice of sequential medical trials, while staying firmly rooted in frequentist methodology.
