Time for actions in lucid dreams: effects of task modality, length, and complexity

The relationship between time in dreams and real time has intrigued scientists for centuries. The question if actions in dreams take the same time as in wakefulness can be tested by using lucid dreams where the dreamer is able to mark time intervals with prearranged eye movements that can be objectively identified in EOG recordings. Previous research showed an equivalence of time for counting in lucid dreams and in wakefulness (LaBerge, 1985; Erlacher and Schredl, 2004), but Erlacher and Schredl (2004) found that performing squats required about 40% more time in lucid dreams than in the waking state. To find out if the task modality, the task length, or the task complexity results in prolonged times in lucid dreams, an experiment with three different conditions was conducted. In the first condition, five proficient lucid dreamers spent one to three non-consecutive nights in the sleep laboratory. Participants counted to 10, 20, and 30 in wakefulness and in their lucid dreams. Lucidity and task intervals were time stamped with left-right-left-right eye movements. The same procedure was used for these condition where eight lucid dreamers had to walk 10, 20, or 30 steps. In the third condition, eight lucid dreamers performed a gymnastics routine, which in the waking state lasted the same time as walking 10 steps. Again, we found that performing a motor task in a lucid dream requires more time than in wakefulness. Longer durations in the dream state were present for all three tasks, but significant differences were found only for the tasks with motor activity (walking and gymnastics). However, no difference was found for relative times (no disproportional time effects) and a more complex motor task did not result in more prolonged times. Longer durations in lucid dreams might be related to the lack of muscular feedback or slower neural processing during REM sleep. Future studies should explore factors that might be associated with prolonged durations.

Efficient Team actions

Team is a widely represented phenomenon in sport. Despite this fact, sport psychology has yet to answers the question why some teams deliver more successful Performance and produce higher interpersonal satisfaction among athletes than others. While group cohesion, defined as "a dynamic process which is reflected in the tendency for a group to stick together and remain united in the pursuit of its instrumental objectives and/or for the satisfaction of member affective needs" (Carron, Brawley, & Widmeyer, 1997, p.°213) is considered to be one important factor contributing to performance, cognitive aspects of team performance depict a complementary view. More specifically, attitudes, efficacy beliefs, role understanding, common goals, and communication are present in any group of two or more people playing Sport together. The interactions between these cognitions and motivation, cohesion, performance, and satisfaction in teams sport is yet an under researched area in sport psychology.

O(N) Models with Topological Lattice Actions

A variety of lattice discretisations of continuum actions has been considered, usually requiring the correct classical continuum limit. Here we discuss “weird” lattice formulations without that property, namely lattice actions that are invariant under most continuous deformations of the field configuration, in one version even without any coupling constants. It turns out that universality is powerful enough to still provide the correct quantum continuum limit, despite the absence of a classical limit, or a perturbative expansion. We demonstrate this for a set of O(N) models (or non-linear σ-models). Amazingly, such “weird” lattice actions are not only in the right universality class, but some of them even have practical benefits, in particular an excellent scaling behaviour.

Data-driven healthcare: from patterns to actions

The era of big data opens up new opportunities in personalised medicine, preventive care, chronic disease management and in telemonitoring and managing of patients with implanted devices. The rich data accumulating within online services and internet companies provide a microscope to study human behaviour at scale, and to ask completely new questions about the interplay between behavioural patterns and health. In this paper, we shed light on a particular aspect of data-driven healthcare: autonomous decision-making. We first look at three examples where we can expect data-driven decisions to be taken autonomously by technology, with no or limited human intervention. We then discuss some of the technical and practical challenges that can be expected, and sketch the research agenda to address them.

Intentionality in Reference and Action

This essay asks whether there is a relation between action-serving and meaning-serving intentions. The idea that the intentions involved in meaning and action are nominally designated alike as intentionalities does not guarantee any special logical or conceptual connections between the intentionality of referential thoughts and thought-expressive speech acts with the intentionality of doing. The latter category is typified by overt physical actions in order to communicate by engaging in speech acts, but also includes at the origin of all artistic and symbolic expression such cerebral and linguistic doings as thinking propositional thoughts. There are exactly four possibilities by which meaning and action intentionalities might be related to be systematically investigated. Meaning-serving and action-serving intentionalities, topologically speaking, might exclude one another, partially overlap with one another, or subsume one in the other or the other in the one. The theoretical separation of the two ostensible categories of intendings is criticized, as is their partial overlap, in light of the proposal that thinking and artistic and symbolic expression are activities that favor the inclusion of paradigm meaning-serving intentions as among a larger domain of action-serving intentions. The only remaining alternative is then developed, of including action-serving intentions reductively in meaning-serving intentions, and is defended as offering in an unexpected way the most cogent universal reductive ontology in which the intentionality of doing generally relates to the specific intentionality of referring in thought to the objects of predications, and of its artistic and symbolic expression.
