QUANTUM REALITY AND ETHOS: A THOUGHT EXPERIMENT REGARDING THE FOUNDATION OF ETHICS IN COSMIC ORDER

The authors undertake a thought experiment the purpose of which is to explore possibilities for understanding moral principles in analogy with cosmic order. The experiment is based on three proposals, which are described in detail: an ontological, a neurological, and a moral proposal. The ontological proposal accepts from the phenomena of quantum physics that there is a nonempirical domain of physical reality that consists not of material things but of what is philosophically conceptualized as a realm of nonmaterial forms. This realm of forms is the realm of potentiality in physical reality that quantum physics posits as an indivisible Wholeness—the One. It is the ultimate reality because everything empirical is the actualization of its forms. The neurological proposal is the hypothesis that the brain is sensitive to the potentiality waves in the cosmic field, as ordinary measuring instruments in physics are sensitive to potentiality waves at the quantum level, so that the cosmic field can communicate with the human brain. The third proposal assumes that the communication with the cosmic field can translate into moral ideas and actions. Even though the three proposals underlying the thought experiment are highly speculative, they lead to definite implications that make sense in their own right and can be applied in a useful way. From the order of reality some simple rules of conduct follow that are identical with traditional moral rules but have the character of rules of well‐ness, leading to new aspects of Aristotle's concept of eudaimonia and Kant's concept of the highest good. In analogy with the structure of physical reality, where all empirical phenomena are actualizations of nonempirical forms, it is suggested that the structure of morality, too, is that of a tacit, nonempirical form that actualizes in explicit principles and moral acts through our consciousness. The tacit form is thought to exist in the realm of cosmic potentiality, together with all the other forms that the empirical world actualizes. It can appear spontaneously in our consciousness when needed, offering its guidance to our judgment and free will. Because it does not appear in the form of commandments accompanied by threats, the actions of the tacit moral form define a higher level of morality, similar to that offered by some aspects of the Christian teaching, where one acts not out of fear but on the desire to do things right.     

Storage and non-storage components of working memory predicting reasoning: A simultaneous examination of a wide range of ability factors

The current study examined basic cognitive abilities that are related to or included in the concept of working memory (WM): different WM components, three executive functions, simple short-term storage (STM), and sustained attention. Tasks were selected from well-established models and balanced in terms of content. The predictive power of storage and non-storage components of WM was examined. The same analyses were conducted with mental speed as an additional predictor of reasoning. Finally, we investigated whether the identified predictors of reasoning remain relevant when a general factor is considered in the analysis. The analyses revealed that short-term memory accounted for the relationship between complex span measures of WM and reasoning but not for the relationship between coordination and reasoning. These findings remained stable in the context of a mental speed and a general factor. The mental speed factor did not add an incremental contribution to the prediction of reasoning above and beyond short-term memory and coordination. The general factor was mainly built by mental speed tasks and acted as an additional predictor of reasoning besides STM and coordination. Thus, we concluded that reasoning ability can be explained by coordination, STM, and mental speed.     

An analysis of ideomotor action.

This article presents a framework based on the work of R. H. Lotze (1852), W. James (1890), and A. G. Greenwald (1970) for understanding ideomotor actions that tend to arise when individuals watch others perform certain actions. Two principles of ideomotor action induction are distinguished: perceptual induction, in which people tend to perform the movements they see, and intentional induction, in which people tend to perform movements suited to achieve what they would like to see. In 3 experiments, ideomotor hand, head, and foot movements were studied while participants watched a ball traveling toward a target. Results showed strong support for intentional induction, weaker support for perceptual induction, and a strong impact of the effector studied. The representational basis of action induction (stimulus vs. goal representations) and the automaticity of the underlying processing (task-dependent vs. task-independent induction) were considered.     

An ER-fMRI investigation of morphological inflection in German reveals that the brain makes a distinction between regular and irregular forms

The hypothesis that morphological processing is supported by a mental dictionary of stored entries plus a set of mental computations based on rules is examined using event-related fMRI. If a rules-plus-memory model () reflects the actual organization of the language faculty, two distinct patterns of brain activation should be observed for production of German irregular and regular noun and verb inflections. If a connectionist alternative to the rules-and-memory model (, and many others since), which seeks to explain the production of both irregular and regular forms within a single associative memory mechanism, is correct, there should be no neural differentiation between German regular and irregular inflection. The results we report support the existence of substantially differing patterns of activation for regulars vs. irregulars, an outcome that is consistent with the two-component rules-plus-memory account.     

The rise and fall of Hugo Münsterberg

This article addresses the turbulent life of the German-American philosopher and psychologist Hugo Miinsterberg in Germany and his role in founding the psychological laboratories at Freiburg and Harvard. He is best known for his contributions to forensic, industrial, and the “new” experimental psychology. Over a span of twenty years (1897–1916), Miinsterberg rose to become the leading psychologist in the US. When he turned his attention to cultural and political issues, particulary his efforts on behalf of a mutual understanding between Germany and America, he had a serious break with the Harvard administration and later, his colleagues. An advocate for world peace, his final years were marred by World War I which left him embittered and socially isolated. Judged harshly at the time, he is now receiving the recognition that posterity did not tender him.     

Perceptual filling-in of negative coloured afterimages

Filling-in of brightness, colour, and texture refers to the perceptual spreading of surround features onto the target area. This phenomenon has been extensively investigated in real images. Here, we study colour spreading in afterimages of disk-ring patterns, using a variety of colour combinations. We show that colour filling-in and filling-out in afterimages follow rules different from those found for real images, suggesting that the brain treats afterimages as genuine 'stimuli'.     

Dynamic properties of an ultrafine-grained Mg–Zn–Zr alloy

The effect of ultrafine-grained structure formation in Mg–Zn–Zr alloy ZK60 on its mechanical response was investigated at strain rates ranging from quasi-static to dynamic regimes. The study demonstrated that the strength characteristics of the material rise significantly with increasing strain rate, while its ductility is reduced. These effects are particularly pronounced in the dynamic loading regime, at strain rates in the (1?5)?×?10²?s^?1 range. In the ultrafine-grained alloy ZK60, the energy absorption per unit volume, W, is enhanced by grain refinement by a factor as high as eight for the highest strain rate of 5?×?10²?s^?1 investigated. The analysis is focused on the microstructure features that bring about the observed improvement of the tensile characteristics, as well as the deformation and fracture modes prevalent at different strain rates. The results obtained contribute to the exploration and understanding of dynamic behaviour of magnesium alloys.
